The present invention relates to a power transmission for vehicle in which the rotational torque of a crankshaft of an internal combustion engine is transmitted to a load-side transmission mechanism through a clutch and a fluid transmission means. [Background Art]
A power transmission system for vehicle of the "above-mentioned type in which a one way clutch composed of a plurality of sprags for making lock engagement with an opposite circumferential surface when the rotating speed of an input shaft reaches or exceeds a predetermined value is used as a clutch and in which a torque converter is used as a fluid transmission means has been known (see, for example, Patent Document 1).
[Patent Document 1]
Japanese Patent Laid-Open No. 2001-295867 (paragraphs [0015] and [0016])
In the power transmission system for vehicle disclosed in Patent Document 1, a kick starter gear train is provided between a transmission input shaft and a transmission output shaft of a transmission which is a load-side transmission mechanism, and the drive force of a kick starter is inputted to the load-side transmission mechanism.
[Disclosure of the Invention] [Problems to Be Solved by the Invention] Therefore, to prevent transmission of the starting drive force of the kick starter to the drive wheel side, the gear must be shifted to neutral at the time of starting, and, thus, there is a room for improvement in operationality.

In addition, the starting drive force of the kick starter is transmitted from the kick starter gear train through the torque converter of the crankshaft and the one-way clutch so as to turn the crankshaft, so that load is high.
The present invention has been made in
consideration of the above-mentioned points. Accordingly, it is an object of the present invention to provide a power transmission system for vehicle with which it is possible to simplify a starting means, to reduce the number of component parts, and to contrive a reduction in cost and which is excellent in operationality at the time of starting. [Means for Solving the Problems]
To attain the above object, the invention as set forth in claim 1 resides in a power transmission system for vehicle, including a clutch and a fluid transmission means through both of which a rotational torque of a crankshaft of an internal combustion engine is transmitted to a load-side transmission mechanism, wherein the clutch and the fluid transmission means are both provided on one side of the crankshaft, and a drive force of a starting means is inputted directly to the other side of the crankshaft.
Since the drive force of the starting means is inputted directly to the crankshaft, it is unnecessary to provide the load-side transmission mechanism with a shift gear for selectively establishing a neutral condition or
the like means, the starting mechanism is simplified, the number of component parts is reduced, a reduction in cost can be contrived, a shifting operation is not needed at the time of starting, and operationally is enhanced.
In addition, the load at the time of starting is small, and the starting operation can be facilitated.
Since the drive force of the starting means is inputted directly to the side, opposite to the side where the clutch and the fluid transmission means are provided, of the crankshaft, a good weight balance can be easily attained.
The invention as set forth in claim 2 is characterized in that, in the power transmission system for vehicle as set forth in claim 1, the fluid transmission means is a torque converter, and the load-side transmission mechanism is a gear mechanism having a fixed speed change ratio.
With automatic speed change attained by the torque converter and with the load-side transmission mechanism being a gear mechanism having a fixed speed change ratio, it is possible to configure the load-side transmission
mechanism as a gear mechanism having a reduced number of component parts, and to thereby contrive reductions in size and weight and a reduction in cost.
The invention as set forth in claim 3 is characterized in that, in the power transmission system for vehicle as set forth in claim 1 or 2, an AC generator is provided on the side, on which the drive force of the starting means is inputted, of the crankshaft.
Since the clutch and the fluid transmission means are disposed on one side of the crankshaft and the AC generator is disposed together with the starting means on the other side, a good weight balance is attained, the operational stability of the vehicle body can be enhanced when the crankshaft is mounted on the vehicle body while being directed in the left-right direction, and a higher compactness in the vehicle width direction can be contrived.
The invention as set forth in claim 4 is characterized in that, in the power transmission system for vehicle as set forth in claim 3, the drive force of the starting means is inputted to a shaft end, located on
the outer side relative to the AC generator, of the crankshaft.
Since the drive force of the starting means is inputted to the shaft end, located on the outer side relative to the AC generator, of the crankshaft, the starting means main body can be disposed in the exterior of the internal combustion engine, an optimum starting means among a cell motor, a kick starter, and a recoil starter can be selectively used and changed according to the machine model, and versatility is enhanced.
The invention as set forth in claim 5 is characterized in that, in the power transmission system for vehicle as set forth in claim 1, the starting means is a kick-type starting means, and an exhaust pipe and a muffler are disposed on the opposite side, with respect to the vehicle body, of the kick-type starting means.
Since the kick-type starting means and the muffler (and the exhaust pipe) are provided on the opposite sides with respect to the vehicle body, the muffler and the exhaust pipe can be laid out without taking into account the movable range of a kick pedal. This enhances the
degree of freedom in layout, and appearance can be enhanced by disposing a rear end portion of the muffler at a forwardly deviated position.

Now, one embodiment of the present invention will be described below, based on Figs. 1 to 3.
A side view of a motorcycle to which the power transmission system according to the present embodiment has been applied is shown in Fig. 1, and a plan view of the same is shown in Fig. 2.
The motorcycle 1 has a structure in which a power unit 10 is suspended at the center of a vehicle body frame 2, a front wheel 4 is shaft-supported by a front fork 3 rotatably borne on a front portion of the vehicle body frame 2, and a rear wheel 6 is shaft-supported on the rear end of a rear fork 5 which has its front end movably supported by a central frame of the vehicle body and extends rearwards.
The upper side of the rear wheel 6 is covered with a seat 7.
The power unit 10 has a structure in which an
internal combustion engine 11 and a load-side gear mechanism 12 are integrated with each other, and a vertical sectional view thereof is shown in Fig. 3.
A left unit case 13L and a right unit case 13R constituting left and right halves of a unity of a crankcase of the internal combustion engine 11 and a gear case of the gear mechanism 12 are coupled to each other, thereby forming a crank chamber and a gear chamber therein.
A crankshaft 15 disposed in the state of being directed in the left-right direction of the vehicle is borne on the left and right unit cases 13L and 13R through bearings 16L and 16R.
In the internal combustion engine 11, a piston 18 slidably fitted in a cylinder bore in a cylinder block 17 and the crankshaft 15 are connected to each other through a connecting rod 19.
A cylinder head 20 joined to the cylinder block 17 defines a combustion chamber 21 between itself and the top surface of the piston 18, and is provided therein with intake and exhaust valves (not shown) for opening and closing intake and exhaust ports communicated with
the combustion chamber 21.
A camshaft 22 for driving the intake and exhaust valves is set parallel to the crankshaft 15 and is rotatably borne on the cylinder head 20.
The gear structure 12 has a structure in which an input shaft 25 and an output shaft 26 disposed in parallel to the crankshaft 15 are rotatably borne on the left and right unit cases 13L and 13R, a primary speed reduction driven gear 25a is mounted to an end portion projecting rightwards from the right unit case 13R of the input shaft 25, a driven gear 2 5b is formed on the left inner side, a drive sprocket 2 6a is mounted to an end portion projecting toward the left outer side from the left unit case 13L of the output shaft 26, a driven gear 26b is fitted on the right inner side, and the driven gear 26b and the drive gear 25b are meshed with each other.
A chain 27 is set between the drive sprocket 26a projecting to the outside from the output shaft 26 and a driven sprocket 6a (see Fig. 1) formed as one body with the rear wheel 6, for constituting a final speed reduction mechanism.
A centrifugal clutch 30, a torque converter 40, and a primary speed reduction drive gear 48a are sequentially disposed on a right-side portion, projecting rightwards from the right unit case 13R, of the crankshaft 15 in this order from the right end toward the inner side, and the primary speed reduction drive gear 4 8a is meshed with the primary speed reduction driven gear 25a of the gear mechanism 12.
A right side cover 2 8 is joined to the right end surface of the right unit case 13R. The cover 28 covers the primary speed reduction mechanism composed by meshing of the primary speed reduction drive gear 48a and the primary speed reduction driven gear 2 5a, the centrifugal clutch 30, and the torque converter 4 0 from the right side.
The centrifugal clutch 3 0 has a structure in which an inner boss portion 32 for holding the base end of an inner plate 31 of a clutch inner is spline-fitted over a right end portion of the crankshaft 15, and clutch weights 34 are inclinably supported respectively on a plurality of support shafts 33 projected on the outer
circumferential end side of the inner plate 31 in parallel to the crankshaft 15
An outer plate 35 of a clutch outer has a cylindrical portion covering the clutch weights 34 with its inner circumferential surface opposed to the clutch weights 34, and an outer boss portion 36 for holding the base end of the outer plate 35 is turnably supported on the crankshaft 15 through a bearing 3 7 and is supported on the inner boss portion 32 through a one-way clutch 38.
As the crankshaft 15 is rotated, the clutch inner is rotated as one body with the crankshaft 15, but the rotational torque is not transmitted to the clutch outer due to the presence of the one-way clutch 38.
When the rotating speed of the crankshaft 15 exceeds a predetermined speed, the inclination of the clutch weights 34 is increased, which acts on the clutch outer 3 5 to engage the clutch, whereby the clutch outer is rotated.
Incidentally, the one-way clutch 38 can transmit the rotational torque from the clutch outer side to the clutch inner side.
The torque converter 4 0 disposed adjacently to the side of the right unit case 13R relative to the centrifugal clutch 30 includes a pump impeller 41 integrally coupled to the outer boss portion 36 for holding the base end of the outer plate 35, a turbine impeller 42 opposed to the pump impeller 41, and a stator impeller 43 disposed between these impellers 41 and 42.
A stator boss portion 44 for holding the base end of the stator impeller 43 is spline-fitted over a cylindrical stator shaft 45, the stator shaft 45 is shaft-supported on the crankshaft 15 through a bearing 46 and supported on the right unit case 13R through a free wheel 47, and the stator impeller 43 can be rotated in one direction as one body with the stator shaft 45.
A cylindrical turbine shaft 4 8 for holding the base end of the turbine impeller 42 is rotatably supported on the stator shaft 45 through a bearing 49, and the primary speed reduction drive gear 48a is formed at a left end portion of the turbine shaft 48.
A side cover 50 for covering the back surface of
the turbine impeller 42 is integrally coupled to the pump impeller 41, and a free wheel 51 for transmitting a back load is interposed between the side cover 50 and the turbine shaft 48.
When the rotating speed of the crankshaft 15 exceeds a predetermined speed and the centrifugal clutch 3 0 is engaged to cause the pump impeller 41 to rotate together with the clutch outer 35, a working oil in the torque converter 40 flows from the side of the outer circumference of the pump impeller 41 by way of the turbine impeller 42 and the stator impeller 43 restricted in rotation by the free wheel 47 back to the side of the inner circumference of the pump impeller 41 so as to transmit the rotational torque of the pump impeller 41 to the turbine impeller 42, thereby driving the turbine shaft 48 integral with the turbine impeller 42 to rotate, i.e., driving the primary speed reduction drive gear 48a to rotate.
When the rotating speed of the turbine impeller 42 is increased to approach the speed of the pump impeller 41, the stator impeller 43 is rotated idly by the free wheel 47, and the impellers 41, 42 and 43 are rotated as
one body at a high efficiency as a fluid coupling.
Thus, the torque converter 40 displays an automatic speed reduction function.
When a back load at the time of speed reduction is inputted from the side of the gear mechanism 12 to the turbine shaft 4 8 through the primary speed reduction mechanism, the rotational torque is directly transmitted to the pump impeller 41 through the side cover 50 due to the engagement of the free wheel 51, and the rotation of the outer plate 36 integral with the pump impeller 41 is transmitted through the one-way clutch 38 to the crankshaft 15, resulting in engine brake.
On the other hand, an AC generator 60 is attached to a left side portion projecting leftwards from the left unit case 13L of the crankshaft 15, with a chain sprocket 56 (around which a power transmission chain 55 is wrapped) being interposed between the left unit case 13L and the AC generator 60.
An outer rotor 61 of the AC generator 60 is fitted over a left end portion of the crankshaft 15, and the outer rotor 61 is fastened to the crankshaft 15 by a bolt
64 screwed into the left end of the crankshaft 15, with a boss member 65 therebetween.
A left side cover 63 for covering the AC generator 60 from the left side is joined to a left end surface of the left unit case 13L.
The left side cover 63 is provided with an opening 63a at its portion opposed to the shaft end of the crankshaft 15, and an inner stator 62 of the AC generator 60 is supported on a peripheral edge portion of the opening 63a.
The boss member 65 for fixing the outer rotor 61 to the left end of the crankshaft 15 is provided with ratchet teeth 65a projected leftwards in an annular form at an end portion penetrating through the opening 63a in the left side cover 63 and projecting to the outside.
Therefore, in the AC generator 60, the inner stator 62 is fixedly supported on the left unit case 13L through the left side cover 63, and the outer rotor 61 is rotated as one body with the crankshaft 15.
A kick starter 70, which is a starting means, is
provided on the left side relative to the AC generator 60 and on the outer side relative to the left side cover 63.
A starter cover 71 joined to a left end surface of the left side cover 63 so as to cover a drive transmission mechanism of the kick starter 70 is provided, on the right-side inner surface of a front portion thereof, with a cylindrical support portion 71a projecting coaxially with the crankshaft 15, and a ratchet shaft 72 is fitted in the cylindrical support portion 71a in a turnable and axially slidable state.
The ratchet shaft 72 is provided with a driven helical gear 73 at an exposed portion ranging to the right end thereof, a ratchet wheel 74 is attached to the right end, and ratchet teeth 74a formed at an end portion projecting in an annular form to the right side of the ratchet wheel 74 are opposed to the ratchet teeth 65a of the boss member 65 fixed to the left end of the crankshaft 15.
A friction spring 75 interposed between the starter cover 71 and the ratchet wheel 74 biases the ratchet shaft 72 together with the ratchet wheel 74 leftwards.
When the ratchet wheel 74 is moved rightwards against the friction spring 75, the ratchet teeth 74a of the ratchet wheel 74 are meshed with the ratchet teeth 65a of the boss member 65.
A bearing boss portion 71b is bulged inwards at a side wall of a rear portion of the starter cover 71, a kick shaft 76 penetrates through and is turnably borne on the bearing boss portion 71b, the left end of the kick shaft 76 projects to the left outer side, and the right end of the kick shaft 76 is turnably fitted in the left side cover 63.
A drive helical gear 77 is integrally fitted over the kick shaft 76 and is biased in one rotating direction by a return spring 78, and the drive helical gear 77 is meshed with the helical gear 73 of the ratchet shaft 72.
A kick pedal 79 is vertically oscillatably mounted to the left end of the kick shaft 76, with its base end portion attached to the left end.
Therefore, when the kick pedal 79 is stepped in and the kick shaft 76 is rotated against the return spring 78, the drive helical gear 77 is rotated as one body with the
kick shaft 76, the driven helical gear 73 meshed with the drive helical gear 77 is slid rightwards against the friction spring 75 while rotating together with the ratchet shaft 72, and the ratchet teeth 74a of the ratchet wheel 74 are meshed with the ratchet teeth 65a of the boss member 65, whereby the crankshaft 15 is forcibly rotated, and the internal combustion engine 11 can be started.
The rotational torque of the crankshaft 15 generated upon stepping-in of the kick pedal 79 at the time of starting rotates only the clutch inner of the centrifugal clutch 30 because the rotating speed is low. The rotational torque is not transmitted to the clutch outer and the subsequent drive transmission system, so that the starting operation can be achieved lightly and easily.
Thus, in the present power transmission system, the drive force of the kick starter 70 is inputted directly to the crankshaft 15. Therefore, it is unnecessary to provide the gear mechanism 12 on the load side with a shifting device for selectively establishing a neutral condition or the like means, the starting mechanism is
simplified, the number of component parts is reduced, and a reduction in cost can be contrived. In addition, a shifting operation is not needed at the time of starting, and operationallty is enhanced.
Since the kick starter 70 is located at the left end of the crankshaft 15 and is engaged with and turned as one body with the crankshaft 15 through the sliding of the ratchet wheel 74 at the time of starting, the kick starter 70 is separate from the crankshaft 15 at other times than the time of starting, so that higher output characteristics can be contrived without increasing the inertial mass of the crank system.
Since the centrifugal clutch 3 0 and the torque converter 40 are disposed on one side of the crankshaft 15 and the AC generator 60 is disposed together with the kick starter 70 on the other side of the crankshaft 15, a good weight balance on the left and right sides can be attained, the operational stability of the vehicle is enhanced, and a higher compactness in the vehicle width direction can be contrived.
The power transmission system according to the
present embodiment is a system in which automatic speed change is achieved by the torque converter 40, and the gear mechanism 12 has a fixed speed change ratio by the meshing of a set of gears 25b and 26b, so that the gear mechanism 12 does not need a shifting device, has a small number of component parts, is simple in structure, and it is possible to contrive reductions m size and weight and a reduction in cost.
Incidentally, referring to Figs. 1 to 3, the exhaust pipe 23 extended downwards from the cylinder head 20 inclined forwards nearly to be substantially horizontal of the internal combustion engine 11 extends rearwards along the lower surface of the right side cover 28 while being skewly deviated to the right side, then constitute the muffler 24, and extends rearwards on the right side of the rear wheel 6 while directing slightly upwards.

Since the muffler 24 is provided on the right side of the vehicle body and disposed on the opposite side of the kick starter 70, the muffler 24 and the exhaust pipe 23 can be laid out without taking into account the movable range of the kick pedal 79, so that the degree of
freedom in layout is enhanced. In addition, with a rear end portion of the muffler 24 disposed in the state of being deviated forwards, the overall length of the muffler 24 can be reduced, and appearance can be enhanced.
While the kick starter 70 has been used as a starting means in the above-described embodiment, an example in which a recoil starter 90 is used in place of the kick starter 70 is shown in Fig. 4.
The structure of other members of the power unit than the recoil starter 90 is the same as in the above embodiment, so that the members are denoted by the same symbols as used above.
The outer rotor 61 of the AC generator 60 is screwed and fastened to the left end of the crankshaft 15 through a boss member 8 0 by a bolt 81, and the inner stator 62 is fixedly supported on a left side cover 82 for covering the AC generator 60.
The boss member 80 penetrates through the center of the left side cover 82, the base end of a bowl-shaped ratchet wheel 91 is attached to a projecting left end portion of the boss member 80, and a ratchet pawl 91a of
the ratchet wheel 91 is projected leftwards from the ratchet wheel 91.
A boss 92a is projected on the inside surface of the starter cover 92 covering the ratchet wheel 91 from the left side, coaxially with the crankshaft 15, and a starter pulley 93 is turnably shaft-supported on the boss 92a.
The starter pulley 93 is biased in one rotating direction by a coil form return spring 96, and an end portion of a rope 97 wound around the outer circumference of the starter pulley 93 is bound to a starter grip 98 disposed in the exterior of the starter cover 92.
An oscillating ratchet pawl 94 is shaft-supported on the right side surface of the starter pulley 93 by a pin 95, and a friction plate 99 is fixed to the boss 92a so as to make sliding contact with the right side surface of the oscillating ratchet pawl 94. When the oscillating ratchet pawl 94 is rotated together with the starter pulley 93, a tip end portion thereof is oscillated in the direction of the outer circumference due to the sliding contact with the friction plate 99, to become capable of
engagement with the ratchet pawl 91a of the ratchet member 91 integral with the crankshaft 15.
Therefore, when the starter grip 98 is pulled to thereby rotate the starter pulley 93 through the rope 97, the oscillating ratchet pawl 94 rotated together with the starter pulley 93 makes sliding contact with the friction plate 99, whereby the tip end portion thereof is oscillated to be engaged with the ratchet pawl 91a of the ratchet member 91, and the crankshaft 15 is thereby rotated, to start the internal combustion engine 11.
The drive force of the starting means is inputted to the shaft end, located on the outer side relative to the AC generator 60, of the crankshaft 15, and the starting means main body can be disposed in the exterior of the internal combustion engine. Therefore, as in this example, the recoil starter 90 can be easily mounted in place of the kick starter 70.
Furthermore, a cell motor can also be mounted, so that an optimum starting means among a cell motor, a kick starter, and a recoil starter can be selectively used and easily changed according to the machine model, which
promises high versatility. [Explanation of Characters]
