[Industrial Field of the Invention]
The present invention relates generally to body structure of a motorcycle and more particularly to body structure which can be made thinner, and reduced in size and weight.
[Description of the Related Art] As one of body frame structure of motorcycles, diamond-type frame structure utilizing an engine as part of

a body frame is known. Among such frame structure, one of backbone types having one main frame disposed in a longitudinal direction of a body frame above an engine comprises: the main frame; a pair of right and left pivot plates welded to the rear end of the main frame and disposed so as to extend generally vertically; a pair of right and left seat rails extending backward from a rear part of the main frame; and lower frames disposed under the seat rails and obliquely connecting the seat rails to the pivot plates. Further, a rear arm is connected to a middle part of each cff the pivot plates, and lower ends thereof serve as an engine-hanging part and a stand supporting part (see Japanese Unexamined Patent Publication No. 10-29582, for example).

[Problems to be Solved by the Invention] When adopting pivot plate structure such as the one described above, a pair of pivot plates serves as a pivot unit for the rear arm, a connection with the lower frames, and an engine hanger as well as the stand supporting part. Therefore, the pivot plates have to be highly rigid and are sometimes formed by casting or forging. However, when manufactured in such a way, the pivot plates get larger and heavier, and their costs are to be raised in the end. Further, the connection between each of the pivot plates and the main frame, etc. requires a long effective length for weld, and it has to be reinforced with a plurality of patches. These are the factors that made the body frame larger, heavier and more expensive. Thus, it
3

is desired to make the body frame more compact, lighter and less expensive by altering the frame structure including the pivot plates. The object of the present invention is to meet such demands.
[0004]
[Means for Solving the Problems]
For the purpose of solving the above problems, the

The middle part of each support 43 is generally turned square U-shaped in section to cover the lower part of the corresponding extension 12 from inside the body frame 4. The lower part of the downward extension 12 is fitted into the U-shaped middle part of said support 43 and welded completely. The supports 43 can easily be made by, for example, pressing a plate of an appropriate metal such as iron plate.
[0029]
As shown in Figs. 8 and 9, a side stand-supporting part 47 is mounted on the outside of the lower part of the left downward extension 12 so as to overlap the lower part as seen from the left side of the body frame 4. An upper part of the side stand-supporting part 47 is welded to the cross pipe 42. The side stand-supporting part 47 can be made of appropriate metals such as iron by appropriate methods such as press molding.
[0030]
The side stand-supporting part 47 has a slope 47a extending downward, off to the left. The slope 47a has a hole 47b in it and is provided with a pin 47c. In this embodiment, the side stand-supporting part 47 is made separately from the
14

support 43 and is attached to either the right or the left side of the body.
[0031]
As shown in Figs. 2 and 6, a rotating shaft 48 of the main stand 29 is inserted into the collar's 46 of the right and left main stand-supporting parts 45 and fastened with a bolt; accordingly the main stand 29 is rotatably supported from the lower frames 7. The reference numeral 49 is a return spring, which is, in a tensioned state, set between a stay 50 on the downward extension 12 and a stay 51 on the main stand 29.
[0032]
On the other hand, the upper end of the side stand 28 forks into to branches 52. The side stand 28 is fitted to the side stand- supporting part 47 so as to catch the slope 47a between the two branches 52 and is journaled rotatably by a bolt and a nut. A return spring 53 for the side stand 28 is , in a tensioned state, set between the pin 47c and a stay 54 on the side stand 28.
[0033]
On each side of the body frame 4, the rear end of the lower frame 7 is welded to the bottom of a rear part of the seat rail 6. On the left side of the body frame 4, provided in the vicinity of the weld is a turned square U-shaped grip 56 with its one end fixed to part of the seat rail 6 behind the weld and another end fixed to the rear end of the lower frame 7 in front of.the weld.
[0034]

On each side of the body frame 4, a reinforcing plate 57 is disposed between a middle part of the seat rail 6 and a middle part of the lower frame 7 to link the both members together. Cushion brackets 58 to support the upper end of the rear cushion 15 are positioned slightly in front of the reinforcing plate 57 as seen from either side of the body frame 4.
[0035]
On each side of the body frame 4, the lower end of the reinforcing plate 57 is welded to the lower frame 7 , and a bracket 59 is provided to part of the lower frame 7 near the weld so as to project downward. A pillion footrest 59a is mounted on the lower end of each bracket 59.
[0036]
As shown in Figs. 4 and 5, on each side of the body frame 4, the reinforcing plate 57 and a reinforcing plate 60, which is in contact with and extending along the inner side surface of the seat rail 6, are formed as a single piece. Each reinforcing plate 60 is shaped so as to be in contact with the inner side surface, the top surface, and the bottom surface of the seat rail 6 and welded to the top and the bottom of the seat rail 6. A cross pipe 61 is supported at its one end in a hole made in the right reinforcing plate 60 and at the other end in a hole made in the left reinforcing plate 60 so as to make a gap "d" between the cross pipe 61 and the seat rail 6 on either side of the body frame 4. The cross pipe 61 is welded to the edges of the holes of the right and left reinforcing
16

plate 60. Two cushion brackets 58 are welded to the middle part of the cross pipe 61. [0037]
Two cross members 62 and 64 are provided behind the cross pipe 61, between the right and left seat rails 6. A seat-supporting stay 64 is provided on each seat rail 6 (Fig. 5) . The reference numeral 65 in Fig. 4 is a stay which projects outside at the rear end of each main member 10.
[0038]
Now the arrangement of the engine 3 and some other components relative to the body frame 4 will be described. As shown in Figs. 1 and 3, on each side of the body frame 4, an upper middle part of a crankcase 71 of the engine 3 is supported by a hanger 34 to the bottom of the main member 10, an upper rear part of the crankcase 71 is supported by a mounting part 72, above the pivot 13, of the pivot unit 12, and a lower rear part of the crankcase 71 is supported by the engine-hanging part 44.
[0039]
A footrest holder 74 is disposed by a rear part of the crankcase 71 on each side of the body frame 4. The upper and lower ends of each footrest holder 74 are supported by the pivot 13 and the cross pipe 42, respectively (Fig. 2) . Each footrest holder 74 is generally L-shaped, having a forward protrusion 73 at a lower part.
[0040]
The footrest holders 74 can easily be made of appropriate
17

metals such as iron plate by appropriate methods such as press molding. A front footrest 75 is mounted on an upper part of the forward protrusion 73 of each footrest holder 74 . A support shaft 76 is mounted on a lower part of the forward protrusion 73 of the left footrest holder 74. A gearshift lever 77 is mounted on the support shaft 76 so as to be freely swingable. The movement of the gearshift lever 77 is transmitted through a linkage mechanism 78 to a gearshift shaft 79.
[0041]
An air cleaner 80 is disposed in the generally triangular space, as seen from either side of the body frame 4, among the pivot unit 11, the seat rails 6, and the lower frames 7. A rear left part of the air cleaner 80 is dented to the right to make a dent 81, and the rear cushion 15 is disposed generally vertically in the dent 81, at generally the center of the body frame 4.
[0042]
The air cleaner 80 is disposed in front of the rear wheel 2 and traverses the width of the body frame 4. The air cleaner 80 has a lid (not shown) on the right side of the body frame 4 and can be opened and closed from the right side. On each side of the body frame 4, a top stay 80b of the air cleaner 80 engages with the seat rail 6 and a bottom stay 80a of the air cleaner 80 is joined to a stay 11a of the pivot unit 11 so as to support the air cleaner 80 in the body frame 4.
[0043]
A carburetor 8 3 is disposed separately from the air cleaner
18

80 in a longitudinal direction of the body with the pivot unit 11 disposed therebetween, and a connecting tube 82 extending forward from the air cleaner 80 is connected to the carburetor 83. On the other hand, the four-cycle engine 3 is disposed in a relatively high position so that its air intake route to its cylinder head 70 can be arranged straight; accordingly the cylinder head 70 is partially hidden by the main member 10 as seen from either side of the body frame 4.
[0044]
The connecting tube 82 extending from the top of the air cleaner 80 is disposed so as to raise part of the tube beyond the top of the seat rail 6 as seen from either side of the body frame 4, and leads to the carburetor 83 through the space among a rear part of the right main member 10, a rear part of the left main member 10, and the top of the pivot unit 11.
[0045]
One end of a resonator 84 is connected to a front part of the connecting tube 82 near the connection between the tube and the carburetor 83. The resonator 84 is formed into long pipe shape generally horizontally disposed in a longitudinal direction, and the rear end of the resonator 84 extends to a space between a front part of a fuel tank 85 and a front part of the air cleaner 80. The fuel tank 85 is supported on the right and left seat rails 6, and the seat 27 is disposed on the fuel tank 85 so as to be openable and closable.
[0046]
A secondary-air control valve 86 for controlling
19

secondary air supplied to an exhaust system is disposed in front of the carburetor 83, between the right and left main members 10, and connected to the cylinder head 7 0 through a tube 87 and to the clean side of the air cleaner 80 through a tube 88. The tube 87 is supported by a stay 33.
[0047]
Further, a sub-air cleaner 90 is disposed in the middle space between the front ends of the right and left main members, and is connected to the carburetor 83 through piping 91. Also, a blowby gas hose 92 extends from the central portion of the upper surface of the rear of the crankcase 71 to the right side of the body. The hose is further disposed so that it passes by the side of the main member 10 to be connected to the front of the clean side of the air cleaner 80, avoiding the the-rmal effect from the engine 3.
[0048]
Also, as shown in Figs. 1 and 2, a portion lower than a rear cowl 24 of the air cleaner 80 and the side of the pivot unit 11 are covered with a pivot cover 19. The pivot cover 19 is a generally Y-shaped member, as viewed from either side of the body, and is made of an appropriate material such as a resin. Further, the pivot cover 19 overlaps the outside of a footrest holder 74, and its central portion is fastened together with the engine 3 against the footrest holder 74 and the pivot unit 11. Also, an upper portion of the pivot cover 19 extends along a lower end of the rear cowl 24, and its front portion is mounted on a stay 65 provided at the rear end of
20

the main member 10.
[0049]
The reference numeral 93 in Fig. 3 designates a radiator reserve tank, which is provided using space formed between the seat rail 6 on the left side of the body and the lower frame 7, and a portion of the reserve tank overlaps a fuel tank 85 as seen from either side of the body. The reference numeral 8 designates an exhaust pipe, which extends from the front of a cylinder head 70 and proceeds backward, passing under the crankcase 71 to be connected to a muffler 9. The muffler 9 extends, as shown in Fig. 2, outwardly of the right side of the body, overlaps the right side of a rear wheel 2 and further extends downwardly of the pillion footrest 60.
[0050]
An operation of the present embodiment will now be described. As shown in Figs. 4, 8 and 9, etc., the front end of a handlebar 17 is extended further below the lower end of the pivot unit 11 to form the downward extension 12, on which the support 43 comprising the engine-hanging part 44 and the main stand-supporting part 45, and the side stand-supporting part 47 are provided. Therefore, unlike the one in the prior art, the pivot unit 11 doesn't directly receive heavy loads placed on the support 43 and the side stand-supporting part 47. Accordingly, the required rigidity can be reduced as much, thereby enabling the pivot unit 11 to be compact, lighter, and smaller in size in the direction of the vehicle width. In
particular, if the pivot unit 11 is formed by press molding,

21-

its cost can be considerably reduced.
[0051]
Further, the support 43 and the side stand-supporting part 47 receiving heavy loads from the engine 3, the side stand 28 and the main stand 29, etc. utilize rigidity of the downward extension 12, which is a rectangular pipe. Therefore, each of them becomes compact and lighter, and can be molded easily by press molding, etc., which reduces respective cost as well. Further, the engine-hanging part 44 and the main stand-supporting part 45 are integrally formed as the support 43. Since they are formed as a single piece, the number of parts can be reduced, facilitating the production. Thus, the whole body frame 4 can be compact and lighter, enabling the body to be thinner and reducing the cost thereof.
[0052]
The carburetor 83 and the air cleaner 80 are separately positioned in front and behind of the pivot unit 11, which is formed as a single piece and the back side is covered with the back wall 38. Nevertheless, the piping is arranged smoothly such that the connecting tube 82 is extended above the air cleaner 80 to the front thereof and the space produced between the upper end of the pivot unit 11 and the rear ends of right and left main members 10 is utilized.
[0053]
The engine 3 is of four-cycle type. Therefore, when the carburetor 83 is located in a relatively high position between the right and left main members 10, the piping of the previously
22

described connecting tube 82 extending from above the air cleaner 80 is more advantageous for such arrangement. Thus, location of each of those parts becomes suitable for the four-cycle engine. [0054]
Further, the present invention is not limited to the above embodiment, and various changes and modifications may be made without departing from the spirit and scope of the invention. For example, the pivot unit 11 can be formed integrally with the main members 10. Also, the pivot 13 in the pivot unit 11 can be omitted, and a pivot unit of the rear arm 14 can be provided at the back of the crankcase 71.
[0055]
Further, the pivot unit 11, the support 43 and the side stand- supporting part 47 can be molded not only by press molding but also by appropriate methods such as casting and forging using aluminum alloy, etc. Also, in the above embodiment, the engine-hanging part 44 and the main stand-supporting part 45 are formed as the support 43 integrating two of them. However, the combination of the engine-hanging part 44 and the stand supporting part to be integrated is not limited, and it is possible either to integrate the engine-hanging part 44 and the side stand-supporting part 47 or to integrate both the side stand-supporting part 47 and the main stand-supporting part 45 with the engine-hanging part 44. In the latter case, the support 43 alone has three functions of the engine-hanging unit, the side stand-supporting part and the main stand-supporting
