BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a straddle-type vehicle.
2. Description of the Related Art
A straddle-type vehicle has been known in which a seat is disposed behind a fuel tank, such as a motorcycle (for example, refer to JP-A-5-8780) . This type of straddle-type vehicle is constructed such that a cross member is disposed between right and left seat rails, and the rear of the fuel tank is supported by the cross member.
However, the above-mentioned straddle-type vehicle has great limitations to the layout of other components in the vicinity of the rear of the fuel tank. That is, since the cross ¦ member that supports the rear of the fuel tank has been disposed between the seat rails, the cross member has become obstructive to dispose the components in the vicinity of the rear of the fuel tank. Therefore, it was difficult to improve the flexibility of the layout. Moreover, it was liable to produce a useless space around the cross member.
Particularly, for motorcycles, there is a strong demand for increasing the capacity of the air cleaner to increase the output. However, when the air cleaner is disposed in the
1
vicinity of the rear of the fuel tank, the cross member has become obstructive, making it difficult to increase the capacity of the air cleaner.
SUMMARY OF THE INVENTION
The present invention has been made in light of such circumstances, and an object of the invention is, in a straddle-type vehicle in which the seat is disposed behind the fuel tank, to improve the flexibility of the layout of the components in the vicinity of the fuel tank and to achieve efficient disposition (without useless space) of the vehicle components.
A straddle-type vehicle according to the invention includes: a body frame including a pair of right and left frames; a fuel tank supported at the front by the body frame; a seat disposed behind the fuel tank. The pair of right and left frames each have a mounting portion separated to the right and left. The fuel tank has, at the rear, right and left mounted portions mounted to the mounting portions, respectively, and an upwardly dent recess located between the mounted portions.
According to the straddle-type vehicle, the right and left mounted portions at the rear of the fuel tank are fixed to the mounting portions of the right and left frames, respectively, so that the rear of the fuel tank is supported by the body frame. The fuel tank has a recess that is dent
2
upwardly at the rear between the mounted portions. Therefore, a sufficiently large space can be formed under the rear of the fuel tank. The effective use of the space increases the flexibility of the layout of other components (for example, an air cleaner, a suspension, and a battery) . Disposing the components under the rear of the fuel tank allows efficient disposition of vehicle components.
According to the invention, in the straddle-type vehicle in which the seat is disposed behind the fuel tank, the flexibility of the layout at the rear of the fuel tank can be increased, and efficient disposition of vehicle components can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereafter, an embodiment of the invention will be described in detail based on the drawings.
As shown in Fig. 1, the straddle-type vehicle according to this embodiment is a motorcycle 10. The motorcycle 10 includes a body frame 11, a water-cooled single-cylinder engine
12 suspended and supported by the body frame 11, a fuel tank
13 supported by the body frame 11, and a seat 14. The seat
14 is disposed behind the fuel tank 13.
As shown in Figs. 2 to 4, the body frame 11 includes a steering head pipe 15, a pair of right and left main frames 16R and 16L extending from the steering head pipe 15 toward the lower rear, rear-arm brackets 23R and 23R joined to the rear of the main frames 16R and 16L, a pair of right and left backstays 17R and 17L extending from the rear arm brackets 23R and 23L to the upper rear, and a pair of right and left seat rails 18R and 18L extending from the middle of the main frames 16R and 16L toward the upper rear, respectively. The rear ends of the backstays 17R and 17L are connected to the rear of the sheet rails 18R and 18L, respectively.
4
As shown in Fig. 1, a front fork 19 is rotatably supported by the steering head pipe 15. The front fork 19 has a steering handle 20 at the upper end, and rotatably supports a front wheel 21 by the lower end.
As shown in Figs. 2 and 3, the main frames 16R and 16L have a vertical thickness larger than the lateral thickness (in the vehicle width direction), and are formed in the shape of a flat rectangular pipe having a vertically long cross section. As shown in Fig. 3, the main frames 16R and 16L are separated from the front parts 16a to the central parts 16b, and substantially in parallel from the central parts 16b to the rear. As shown in Fig. 2, the vertical thickness of the front parts 16a of the main frames 16R and 16L are almost equal to the vertical length of the steering head pipe 15. The vertical thickness of the main frames 16R and 16L becomes small as they go to the central parts 16b from the front parts 16a.
As shown in Fig. 3, a cross member 24 extending in the lateral direction (in the vehicle width direction) is disposed between the central part 16b of the left main frame 16L and the central part 16b of the right main frame 16R. The front ends 18a of the seat railsl8R and 18L are connected to the vicinity of the joint portion of the main frames 16R and 16L and the cross member 24 (refer to Fig. 2).
As shown in Fig. 5, the fuel tank 13 has a front upper surface 13a which inclines to the lower front and a rear upper
5
surface 13c which inclines to the lower rear. The boundary between the front upper surface 13a and the rear upper surface 13c is an upper end 13b located at the uppermost of the upper surface of the fuel tank 13. The fuel tank 13 has, on both sides, front sides 13d that protrude laterally as they go to the rear and rear sides 13e that protrude laterally as they go to the front. The rear sides 13e face the occupant's knees during driving. Therefore, the rider can take a posture along the fuel tank 13 by opening the knees appropriately, and thus can ride with a comfortable posture.
As shown in Fig. 7, the rear of the fuel tank 13 has a recess 32 that dents upward as seen from the rear. Specifically, the recess 32 on the back of the fuel tank 13 has curved pieces 32a extending downward from the center toward the right and left sides as seen from the back and a projecting piece 32b (refer to Fig. 5) which is located between the curved pieces 32a and which projects backward. At the lower ends of the curved pieces 32a, ring-shaped brackets 32c are provided.
The projecting piece 32b may smoothly continue to the curved pieces 32a. However, in this embodiment, the projecting piece 32b protrudes upward relative to the curved pieces 32a, and there is a step between the projecting piece 32b and the curved pieces 32a. Thus, the projecting piece 32b is located one step higher than the curved pieces 32a to form a large space under the projecting piece 32b.
6
Then, the mounting structure for the fuel tank 13 will be described. As shown in Fig. 3, a bracket 25 that is substantially triangular, as viewed from the top, is joined to the top of the front parts 16a of the main frames 16R and 16L. The bracket 25 has mounting holes 25a. On the other hand, as shown in Fig. 6, the bottom plate 13k of the fuel tank 13 has mounting holes 33 corresponding to the mounting holes 25a of the bracket 25. The front part of the fuel tank 13 is fixed to the main frames 16R and 16L via the bracket 25 by tightening fastening devices such as bolts (not shown) into the mounting holes 25a and the mounting holes 33.
As shown in Fig. 8, brackets 34R and 34L extending upward are joined to the middle of the seat rails 18R and 18L, respectively. As shown in Fig. 7, the brackets 34R and 34L each have a pair of projections 34a and 34b arranged laterally side by side at a specified interval. The projections 34a and 34b project upward from the seat rails 18R and 18L. The projections 34a and 34b may either be formed in one piece or be formed separately. The projections 34a and 34b have mounting holes 34c (refer to Fig. 8) for a fastening device such as a bolt to pass through. As shown in Fig. 7, the right and left brackets 32c of the fuel tank 13 are placed between the projections 34a and 34b of each of the brackets 34R and 34L of the seat rails 18R and 18L. The rear part of the fuel tank 13 is mounted to the brackets 34R and 34L with a fastening
7
device 35 such as a bolt that passes through the mounting holes 34c of the projections 34a and 34b and the brackets 32c.
The fuel tank 13 is rotatably mounted to the brackets 34R and 34L. Therefore, in a state in which the front part of the fuel tank 13 is not fixed to main frames 16R and 16L, the fuel tank 13 can be rotated with the brackets 32c as a fulcrum. This facilitates works on the vehicle components disposed under the fuel tank 13 by rotating the fuel tank 13 backward into a state in which it erects from the seat rail 18R and 18L.
As shown in Fig. 5, a fuel pump 30 is disposed inside the fuel tank 13. The fuel pump 30 is located about the center of the fuel tank 13 in the front-back direction (in the lateral direction of Fig. 5) . A fill opening 26 is provided in the front upper surface 13a of the fuel tank 13. A cylindrical part 27 with substantially the same diameter as that of the fill opening 26 is formed inside the fill opening 26. A stopper 28 extending in the lateral direction is provided at the lower end of the cylindrical part 27 so that an oil gun 27a may not contact the fuel pump 30 at the time of oil supply. Thus, when inserting the oil gun 27a through the fill opening 26, the tip of the oil gun 27a comes into contact with the stopper 28 to prevent the excessive insertion of the oil gun 27a. The fill opening 26 is closed by a lid 29 (refer to Fig. 1) except the time of oil supply.
As shown in Fig. 9, the upper end 13b of the fuel tank
8
13 and the fuel pump 30 overlap as viewed from the top. That is, the fuel pump 30 is arranged in the vicinity of the upper end 13b of fuel tank 13, and the position having the maximum space in the upper part of the interior of the fuel tank 13 (also see Fig. 5).
As shown in Fig. 5, the bottom plate 13k of the fuel tank 13 has a front bottom 13g inclined toward the upper front, a substantially horizontal center bottom 13h, and a rear bottom 13i inclined toward the lower front. The above-mentioned mounting holes 33 {refer to Fig. 6) are formed at the front - bottom 13g. The center bottom 13h is located lower than the front bottom 13g and the rear bottom 13i.
As shown in Fig. 6, the center bottom 13h has a mounting washer 31 for mounting the fuel pump 30. The mounting washer 31 is shaped like a ring. The mounting washer 31 has a plurality of mounting holes 31a (six pieces in this embodiment) circumferentially at specified intervals. As shown in Fig. 5, the fuel pump 30 is mounted to the mounting washer 31 in such a manner that it is inserted into the fuel tank 13 through the central opening of the mounting washer 31, and then fastening devices such as screws to the mounting holes 31a are tightened. The fuel pump 30 is therefore disposed at the lower part in the fuel tank 13.
As shown in Fig. 6, the bottom plate 13k of the fuel tank 13 has grooves (beads) 36 depressed upward to the right and
9
left of the mounting washer 31 (also see Fig. 10) . The grooves 36 extend substantially along the length of the fuel tank 13 (in the front-back direction).
As shown in Fig. 1, a pivot shaft 37 is provided to the rear-arm brackets 23R and 23L. The pivot shaft 37 pivotally supports the front end of the rear arm 38. The rear end of the rear arm 38 rotatably supports a rear wheel 39 serving as a driving wheel.
The engine 12 is supported by the main frames 16R and 16L and the rear-arm brackets 23R and 23L. The engine 12 has a cylinder 65 extending toward the upper front. The cylinder here indicates the whole body including the cylinder body and the cylinder head. The cylinder 65 may not necessarily extend obliquely upward but may extend upward. The cylinder 65 is connected to an air cleaner 41 via an intake pipe 40 and to a muffler 43 via an exhaust pipe 42.
One end of the intake pipe 40 is connected to the cylinder 65, and the other end of the intake pipe 40 is connected to the air cleaner 41. The intake pipe 40 is disposed lower than both the upper end 65t of the cylinder 65 and the upper end 41t of the air cleaner 41.
A joint portion 30a connected to a fuel supply pipe 61 is provided at the lower end of the fuel pump 30. The fuel ejected from the fuel pump 30 is conveyed to the fuel supply pipe 61 through the joint portion 30a and supplied through the
10
fuel supply pipe 61 into the intake pipe 40. As shown in Fig.
1, the joint portion 30a is disposed higher than the main frames
16R and 16L as seen from the side (higher than the main frames
16R and 16L with reference to the same front-back direction) .
A side cover 62 is mounted to the side of the body frame
11. The side cover 62 covers the side of at least part of the
joint portion 30a. Therefore, the joint portion 30a cannot
be viewed from the exterior.
The air cleaner 41 is formed in a longwise approximately rectangular parallelepiped shape. The vertical length of the air cleaner 41 is longer than any of the front-back length and the lateral length. Here, the vertical length, front-back length, and lateral length indicate the maximum of the vertical length, front-back length, and lateral length, respectively. The intake pipe 40 is connected to the bottom of the front of the air cleaner 41. An intake section 44 to take in air is formed at the upper rear of the air cleaner 41 (refer to Fig. 8). The intake section 44 has intake ports 44a open to the rear so that the air cleaner 41 can take air from the rear.
The air cleaner 41 is disposed at the lower rear of the fuel tank 13. Specifically, as shown in Fig. 1, the air cleaner 41 is disposed under the rear bottom 13i of the fuel tank 13. In this embodiment, the rear of the fuel tank 13 is supported by the seat rails 18R and 18L via the brackets 34R and 34L, respectively, and there is no cross member for supporting the
11
rear of the fuel tank 13 between the right and left seat rails 18R and 18L. The air cleaner 41 can therefore be disposed in a higher position than that of the conventional one or increased in length in the vertical and horizontal directions (refer to Fig. 8) . As shown in Fig. 8, in this embodiment, the upper end 41t of the air cleaner 41 (not shown in Fig. 8, refer to Fig. 1) projects higher than the seat rails 18R and 18L. The upper end 41t of the air cleaner 41 is located higher than the upper ends of the brackets 34R and 34L. As a result, the fuel tank 13 and the air cleaner 41 overlap, as viewed from the side.
As shown in Fig. 8, a downward-extending bracket 55 is connected to each of the seat rails 18R and 18L. On the right and left sides of the air cleaner 41, externally extending mounting portions 41a are provided. The brackets 55 and the mounting portions 41a have a mounting hole 55a for a fastening device such as a screw to pass through. The air cleaner 41 is fixed to the bracket 55 with the fastening device. In this embodiment, the air cleaner 41 is supported only by the seat rails 18R and 18L via the brackets 55.
As shown in Fig. 7, the intake section 44 of the air cleaner 41 is disposed under the recess 32 on the back of the fuel tank 13, particularly, directly below the projecting piece 32b of the fuel tank 13. The projecting piece 32b extends toward the back of the intake section 44 to cover the upper part of the intake section 44.
12
As shown in Fig. 1, the seat 14 is supported by the seat rails 18R and 18L (refer to Figs. 2 and 3) via a bracket (not shown) . The seat 14 is in the shape of a saddle, and has a forwardly projecting piece 45 on its back side that covers the upper part of the intake section 44 of the air cleaner 41 and that enters below the projecting piece 32b of the fuel tank 13.
As shown in Fig. 12, a laterally extending cross member 46 is built between the lower ends of the right and left rear-arm brackets 23R and 23L. A pair of right and left brackets 47 for suspending the engine 12 is connected to the cross member 46. The brackets 47 rotatably support the rotation shaft 48a of a main stand 48. That is, the brackets 47 of the motorcycle 10 serve as both the bracket for the engine 12 and the bracket for the main stand 48. In other words, the bracket for the engine 12 and the bracket for the main stand 48 are used in common.
As shown in Fig. 12, link brackets 49 are joined to the brackets 47. The link brackets 49 function also as a stopper of the main stand 48. When the main stand 48 is turned from the housed state to a standing state {when turned to the direction A in the drawing) , the stopper 48b of the main stand 48 comes into contact with the link brackets 49, preventing an excessive turn of the main stand 48 to held it in a position.
Fig. 11 is a side view showing the right rear-arm bracket
13
23R of the motorcycle 10. The rear-arm bracket 23R is fitted at the lower front with a kick pedal 50, and at the lower end with a stopper 51 for preventing the excessive rotation of the kick pedal 50. At kicking, the rider depresses the kick pedal 50 from the housed state (indicated by numeral 50A). As a result, the kick pedal 50 rotates counterclockwise, as viewed from the right side. When the kick pedal 50 rotates through more than a predetermined angle, the stopper 50a of the kick pedal 50 comes into contact with the stopper 51 to prevent the excessive rotation of the kick pedal 50 . Numeral 50B indicates a state in which the kick pedal 50 is brought out of the housed state, and numeral 50C indicates the state of the kick pedal 50 during rotation.
When the stopper 51 for the kick pedal 50 is disposed at the crankcase of the engine 12, the stopper 51 is liable to cause limitation to the position of the pivot shaft 37 because the stopper 51 is obstructive. In contrast, the stopper 51 is mounted to the body frame 11 (strictly speaking, to the rear-arm bracket 23R) not to the engine 12. This arrangement decreases the limitation to the position of the pivot shaft 37 and so on, increasing the flexibility of layout.
As described above, according to the motorcycle 10, the rear of the fuel tank 13 is supported by the seat rails 18R and 18L via the brackets 34R and 34L, and the cross member for supporting the rear of the fuel tank 13 is not provided. The
14
fuel tank 13 has, at the rear, the right and left ring-shaped brackets 32c mounted to the brackets 34R and 34L of the seat rails 18R and 18L and the upwardly dented recess 32 (the curved pieces 32a and the projecting piece 32b) that is located between the ring-shaped brackets 32c. Thus, there is a sufficient space under the rear of the fuel tank 13. Therefore, the arrangement of the embodiment can increase the flexibility of the layout of the vehicle components by using the space as an installation space for another component (the air cleaner 41 in this embodiment, or alternatively, a suspension or a battery) . Moreover, in this embodiment, since the air cleaner 41 is disposed in the space, the air cleaner 41 can be disposed compact.
In this embodiment, the brackets 34R and 34L extending upward from the seat rails 18R and 18L are used as mounting portions for mounting the rear of the fuel tank 13 to the seat rails 18R and 18L. This arrangement can prevent the mounting portions from protruding inward in the lateral direction (in the vehicle width direction), providing a large space under the rear of the fuel tank 13.
In this embodiment, the mounted portions of the fuel tank 13 are the downwardly extending brackets 32c. This arrangement can prevent the mounted portions of the fuel tank 13 from protruding laterally inward, thereby increasing the space under the rear of the fuel tank 13.
15
As described above, the embodiment ensures a large space under the rear of the fuel tank 13, in which the air cleaner 41 is disposed. This arrangement can increase the capacity of the air cleaner 41, thus increasing the output of the engine 12.
In this embodiment, the upper end 41t of the air cleaner 41 projects higher than the seat rails 18R and 18L, and is located higher than the upper ends of the brackets 34R and 34L. Accordingly, the air cleaner 41 and the brackets 34R and 34L overlap as viewed from the side. Further, the fuel tank 13 and the air cleaner 41 overlap as viewed from the side. That is, part of the air cleaner 41 enters below the fuel tank 13, as viewed from the side. Since the upper part of the air cleaner 41 thus extends to a higher position, the capacity of the air cleaner 41 can be further increased, so that the engine output can be further in-creased.
The air cleaner 41 is longer in the vertical direction than in the front-back direction and the lateral direction, that is, in a vertically long shape. This arrangement allows the space under the rear of the fuel tank 13 to be used effectively. The elimination of wasted space enables efficient arrangement of the air cleaner 41.
In order to increase the capacity of the air cleaner 41, it is also possible to increase the length of the air cleaner 41 in the front-back direction or the lateral direction.
16
However, since other components (in this embodiment, the joint portion 30a of the fuel pump 30 and the battery 60) are often disposed in front and rear of the air cleaner 41, it is difficult to increase the front-back length of the air cleaner 41 because of limitation to the layout of the components. Moreover, increasing the lateral length of the air cleaner 41 results in an increase in the vehicle width, which is not desirable because it causes a bad riding posture of the rider.
The intake port 44a of the air cleaner 41 is disposed between the brackets 34R and 34L. Thus, the space between the brackets 34R and 34L can be used effectively as the installation space for the intake port 44a. Moreover, the intake port 44a of the air cleaner 41 can be disposed in a high position. This arrangement can surely prevent mud and dust fling up from the road from entering the air cleaner 41.
The projecting piece 32b at the rear of the fuel tank 13 covers the upper part of the intake port 44a of the air cleaner 41 and extends to behind the intake port 44a. This arrangement allows water flowing down along the fuel tank 13 to be received by the projecting piece 32b in the event of rain, thus preventing entry of water from above into the intake port 44a of the air cleaner 41.
The seat 14 has the forward projecting piece 45 which covers the upper part of the intake port 44a of the air cleaner 41 and which enters below the projecting piece 32b of the fuel
17
tank 13. Accordingly, the forward projecting piece 45 also prevents the entry of water into the intake port 44a, thus preventing the entry of water into the air cleaner 41 more reliably.
The body frame 11 has the pair of right and left main frames 16R and 16L and the cross member 24 disposed between the main frames 16R and 16L. The front ends 18a of the seat rails 18R and 18L are connected to the vicinity of the joined portion of the main frames 16R and 16L and the cross member 24. This arrangement provides the body frame 11 with sufficient rigidity although no cross member is disposed between the seat rails 18R and 18L.
The air cleaner 41 is supported only by the seat rails 18R and 18L. This simplifies the support structure for the air cleaner 41.
The straddle-type vehicle of the invention is not limited to the motorcycle but may be another straddle-type vehicle such as a four-wheel buggy.
As has been described above, the invention is useful for a straddle-type vehicle such as a motorcycle.-18-
