[0057] The swing arm 16 is supported by a pivot 22 supported by the vehicle frame 11. The pivot 22 is a shaft extending horizontally in the vehicle width direction. The pivot 22 is inserted through the front end of the swing arm 16. The swing arm 16 swings up and down around the pivot 22.

[0058] The rear wheel 15 is supported by an axle 15 a provided at a rear end portion of a swing arm 16 .

[0059] The power unit 12 is disposed between the front wheel 13 and the rear wheel 15 , and is supported by the vehicle frame 11 .

[0060] The power unit 12 is an internal combustion engine and includes a crankcase 23 and a cylinder 24 that accommodates a reciprocating piston. An exhaust port of the cylinder 24 is connected to an exhaust device 25 .

[0061] The output of the power unit 12 is transmitted to the rear wheels 15 via a driving force transmission member that connects the power unit 12 and the rear wheels 15 .

[0062] The saddle-ride type vehicle 10 also includes a front fender 26 that covers the front wheel 13 from above, a rear fender 27 that covers the rear wheel 15 from above, a step 28 for a passenger to put their feet on, and a fuel tank 29 that stores fuel used by the power unit 12 .

[0063] The front fender 26 is attached to the front fork 14. The rear fender 27 and the footrest 28 are provided below the seat 17. The fuel tank 29 is supported by the vehicle frame 11.

[0064] The front frame 19 includes a main frame 31 extending rearward and downward from the front stand pipe 18 , a pair of left and right pivot frames 32 provided at rear lower portions of the main frame 31 , and a down frame 33 extending downward from the front stand pipe 18 .

[0065] The left and right pair of pivot frames 32 support the pivot 22 and support the left and right pair of pedals 28 below the pivot 22. The pedals 28 are driver pedals for the driver to put his feet on. The left and right pair of pivot frames 32 support the left and right pair of rear seat pedals 30s for the passengers to put their feet on via the pedal support bracket 30 extending upward and backward from the pivot frames 32.

[0066] An inner fender 16f is mounted on the swing arm 16 to cover the front portion of the rear wheel 15 from above. A rear suspension 16s is inserted between the swing arm 16 and the rear portion of the vehicle frame 11. The rear suspension 16s is located in the center of the vehicle width and is arranged between the rear wheel 15 and the power unit 12 in a posture tilted rearward and downward.

[0067] The rear frame 20 includes a pair of left and right seat frames 41 extending from rear portions of the main frame 31 toward the rear of the vehicle body, and a pair of left and right sub-frames 42 extending from the left and right pivot frames 32 to the seat frames 41 .

[0068] The front portion of the crankcase 23 of the power unit 12 is fixed to the lower end of the lower frame 33 via the unit bracket 34, and the rear portion of the crankcase 23 of the power unit 12 is fixed to the lower end of the pivot frame 32 via the unit bracket 36. Thus, the power unit 12 is arranged behind the lower frame 33, in front of the pivot frame 32, and below the main frame 31.

[0069] The power unit 12 is a single-cylinder engine (internal combustion engine) in which the cylinder portion 24 is vertically arranged at the front upper portion of the crankcase 23. In addition, the power unit 12 is not limited to an internal combustion engine, but may also be an electric motor. In the case where the power unit 12 is composed of an internal combustion engine, it is not limited to a single-cylinder engine, but may also be a multi-cylinder engine.

[0070] An exhaust device 25 is connected to the front surface of the cylinder 24. The exhaust device 25 includes a first exhaust pipe 25a extending from the front surface of the cylinder 24 to below the power unit 12, a catalyst unit 25b located downstream of the first exhaust pipe 25a, and a muffler 25c located downstream of the catalyst unit 25b.

[0071] An intake passage 60 is connected to the back of the cylinder 24. An air filter 61 is connected to the end of the intake passage 60 on the opposite side from the cylinder 24 (corresponding to the upstream end). The air filter 61 is arranged in a space surrounded by the rear frame 20 below the seat 17. In addition, the air filter 61 is in a hollow box shape, and therefore is also referred to as a housing of the air filter 61 or a box of the air filter 61.

[0072] The saddle-riding type vehicle 10 includes a vehicle body cover 50 that covers various parts of the vehicle frame 11. The vehicle body cover 50 includes a tank cover 51 that covers the fuel tank 29, a pair of left and right side covers 52 that cover the sides of the vehicle body, and a rear cover 53 that covers the lower part of the seat 17 from the left and right outer sides behind the side covers 52. The side covers 52 are located in the front and rear center of the vehicle body when the vehicle body is viewed from the side, and therefore can also be called a center cover.

[0073] exist Figure 1 In FIG. 5 , the pedal supporting bracket 30 , the inner fender 16 f , and the side cover 52 are indicated by two-dot chain lines.

[0074] The saddle-riding type vehicle 10 includes a front wheel brake device 71 for applying braking force to the front wheel 13 and a rear wheel brake device 72 for applying braking force to the rear wheel 15. Each brake device 71, 72 is a hydraulic disc brake composed of a brake disc and a brake caliper. In addition, each brake device 71, 72 can widely apply a known brake device.

[0075] In the saddle-ride type vehicle 10, the ABS regulator 73 is relative to the vehicle width center LC (refer to Figure 4 ) is arranged biased to one side or the other in the outer side in the vehicle width direction (the right side in this structure).

[0076] The ABS modulator 73 controls the braking force of the two brake systems composed of the front wheel brake device 71 and the rear wheel brake device 72. The structure of the ABS modulator 73 is not particularly limited, but the ABS modulator 73 of this structure includes a pump driven by a motor to adjust the hydraulic pressure, a hydraulic circuit connected to the pump, a valve switching the hydraulic circuit, and an electronic control unit controlling the motor, and the ABS modulator 73 functions as a braking force adjustment device to prevent the front wheel 13 and the rear wheel 15 from locking.

[0077] Figure 2 This is a diagram showing the ABS modulator 73 and the surrounding structure from the right side of the vehicle body.

[0078] Figure 2 In FIG. 5 , the side cover 52 is removed, and the pedal support bracket 30, the inner fender 16f, and the muffler 25c are indicated by two-dot chain lines.

[0079] like Figure 2 As shown, the ABS modulator 73 is supported by the main frame 31 at a position above the swing arm 16 and below the air cleaner 61 behind the power unit 12 and in front of the rear suspension 16s.

[0080] A brake pipe 81 and a brake pipe 82 are connected to the upper surface of the ABS modulator 73. The brake pipe 81 is connected to the master cylinder 76 that generates hydraulic pressure by operation of the brake pedal 75, and the brake pipe 82 is connected to the rear wheel brake device 72. The brake pipes 81 and 82 constitute a brake pipe group for rear wheel braking.

[0081] A brake pipe group 85 for front wheel braking is also connected to the upper surface of the ABS modulator 73. The brake pipe group 85 for front wheel braking is composed of a brake pipe 85a connected to a master cylinder for front wheel braking provided on the handle 21 and a brake pipe 85b connected to the front wheel brake device 71. The brake pipe group 85 for front wheel braking is wired along the right side surface of the front frame 19. In addition, the position and structure of the brake pipe group 85 for front wheel braking can widely apply a known structure.

[0082] Next, the brake pipe group (pipes 81 to 83) for rear wheel braking and its related structure will be described. In this description, when the brake pipes 81 and 82 are distinguished, they are described as the first brake pipe 81 and the second brake pipe 82, respectively.

[0083] A brake pedal 75 that functions as an operating element for rear wheel braking is provided around the right pedal 28. The brake pedal 75 is located below the ABS modulator 73 and outside the swing arm 16 in the vehicle width direction, and is operated by the driver's right foot.

[0084] The master cylinder 76 is located behind the brake pedal 75 and below the ABS modulator 73 , and is located outside (on the right side) of the swing arm 16 in the vehicle width direction. The master cylinder 76 generates hydraulic pressure in the first brake pipe 81 in response to operation of the brake pedal 75 .

[0085] A fluid reservoir 77 for rear wheel brakes is disposed above the ABS modulator 73. The fluid reservoir 77 is connected to the master cylinder 76 via a brake pipe 83 (hereinafter appropriately referred to as a third brake pipe 83) to store brake fluid. The third brake pipe 83 extends downward from the master cylinder 76 behind the ABS modulator 73 and is connected to the upper portion of the master cylinder 76.

[0086] Figure 3 It is a magnified representation Figure 2FIG. 8 is a diagram of a brake pipe group 81 to 83 for rear wheel braking and surrounding structures. Figure 4 This is a diagram showing the brake pipe group 81 to 83 and the surrounding structure for rear wheel braking from the rear. Figure 4 In order to facilitate the understanding of the description, the range of the ABS regulator 73 is indicated by a single-dot chain line. Figure 4 The symbol LC in the figure represents the vehicle width center.

[0087] like Figure 3 As shown in FIG. 8 , the first brake pipe 81 extends from the upper portion of the master cylinder 76 through the rear of the ABS modulator 73 and toward the inner side in the vehicle width direction. Figure 4 As shown, the first brake pipe 81 extends obliquely inward and upward in the vehicle width direction so as to connect the connection points of the master cylinder 76 and the ABS modulator 73 at the shortest distance, and passes above the subframe 42. In addition, the first brake pipe 81 passes through the area overlapping with the ABS modulator 73 or the periphery of the area when the vehicle body is viewed from the rear.

[0088] Furthermore, the first brake pipe 81 passes ahead of the third brake pipe 83 and the second brake pipe 82 , that is, passes on the ABS modulator 73 side, which contributes to shortening the first brake pipe 81 .

[0089] By arranging the first brake pipe 81 in this way, the first brake pipe 81 does not protrude beyond the ABS modulator 73 in the vehicle width direction, and the space required for wiring of the first brake pipe 81 can be reduced.

[0090] like Figure 3 As shown, the second brake pipe 82 extends from the ABS modulator 73 toward the rear of the vehicle body and is connected to the rear wheel brake device 72.

[0091] The second brake pipe 82 of this structure is arranged to include: a rear curved portion 82a that extends rearward and upward from the ABS modulator 73 and then bends convexly toward the rear of the vehicle body, a front curved portion 82b that bends convexly toward the front of the vehicle body downstream of the rear curved portion 82a, and a rear extending portion 82c that extends rearward along the upper surface of the swing arm 16 downstream of the front curved portion 82b.

[0092] The rear extension portion 82c is held by a plurality of downstream pipe holding portions 91 provided on the swing arm 16 so as to extend linearly along the upper surface of the swing arm 16. Therefore, when the swing arm 16 swings up and down, the rear extension portion 82c of the second brake pipe 82 moves integrally with the swing arm 16.

[0093] In this structure, a portion of the second brake pipe 82 between the rear curved portion 82 a and the front curved portion 82 b is held by a single upstream pipe holding portion 92 fixed to the subframe 42 .

[0094] The upstream side pipe holding portion 92 is provided at a height overlapping with the ABS modulator 73 in the horizontal direction, and the portion between the rear curved portion 82a and the front curved portion 82b is maintained in a posture with the front lower and the rear higher relative to the vehicle frame 11. The rear curved portion 82a is maintained by the upstream side pipe holding portion 92, and the uppermost portion of the rear curved portion 82a is located above the ABS modulator 73. As a result, the pipe portion of the rear curved portion 82a is located at a position separated from the ABS modulator 73 to the rear, and a sufficient space for arranging the first brake pipe 81 can be ensured between the ABS modulator 73 and the second brake pipe 82.

[0095] Furthermore, the upstream tube holding portion 92 holds the tube portion between the tube holding portion and the rear extension portion 82c as a front curved portion 82b curved convexly toward the front of the vehicle body.

[0096] When the swing arm 16 swings up and down, the downstream portion moves up and down integrally with the swing arm 16 based on the inflection point of the front curved portion 82b. Therefore, it is possible to suppress the bending and movement of the second brake pipe 82 fixed to the frame 11 and the swing arm 16. That is, the front curved portion 82b functions as a bending absorption portion that suppresses the bending and movement of the second brake pipe 82.

[0097] In addition, the rear curved portion 82a and the front curved portion 82b form an S-shape when the vehicle body is viewed from the side. Therefore, it is easy to suppress the second brake pipe 82 from protruding or moving in the vehicle width direction. In addition, the S-shape portion of the second brake pipe 82 overlaps with the rear suspension 16s when the vehicle body is viewed from the side, so it is not conspicuous even if it is exposed in appearance.

[0098] like Figure 4 As shown in the figure, when the vehicle body is viewed from behind, the rear curved portion 82a and the front curved portion 82b are located below the air cleaner 61 and closer to the vehicle width direction inner side than the vehicle width direction outer side of the ABS modulator 73. When the vehicle body is viewed from behind, the rear curved portion 82a and the front curved portion 82b extend in the vehicle body up-down direction in at least one of the area overlapping with the ABS modulator 73 and the surrounding area of ​​the area. Therefore, the space required for the arrangement of the rear curved portion 82a and the front curved portion 82b can be a narrow space in the vehicle width direction, and it is easy to route the rear curved portion 82a and the front curved portion 82b so as not to protrude in the vehicle width direction of the ABS modulator 73.

[0099] Furthermore, the first brake pipe 81 extends in the vehicle width direction intersecting with the second brake pipe 82 in front of the rear curved portion 82a and the front curved portion 82b of the second brake pipe 82 and behind the ABS modulator 73. Thus, the overlapping area of ​​the first brake pipe 81 and the second brake pipe 82 can be minimized. Thus, compared with the case where the first brake pipe 81 and the second brake pipe 82 are arranged in parallel, it is easy to suppress the excessive protrusion of the two pipes 82, 82 in the vehicle width direction. In addition, since a part of the two pipes 82, 82 overlaps in the vehicle body front-rear direction, it is also easy to suppress the excessive protrusion of the two pipes 82, 82 in the vehicle width direction.

[0100] As described above, the saddle-riding type vehicle 10 of the present embodiment is equipped with a brake system in which the ABS modulator 73 is arranged to one side with respect to the vehicle width center LC, and the saddle-riding type vehicle 10 includes: a first brake pipe 81 connected from the master cylinder 76 to the ABS modulator 73; and a second brake pipe 82 connected from the ABS modulator 73 to the rear wheel brake device 72 at the rear of the vehicle body. Figure 4 As shown, when viewing the vehicle body from the rear, the first brake pipe 81 and the second brake pipe 82 intersect.

[0101] According to this structure, the overlapping area of ​​the first brake pipe 81 and the second brake pipe 82 can be minimized, and it is easy to suppress the protrusion of each pipe 81, 82 in the vehicle width direction, etc. Therefore, even if the ABS modulator 73 is arranged offset to the left or right side with respect to the vehicle width center LC, it is easy to suppress the excessive protrusion of each pipe 81, 82 in the vehicle width direction.

[0102] In addition, in the present embodiment, the case where the ABS modulator 73 does not overlap with the vehicle width center LC is exemplified, but even when a part of the ABS modulator 73 overlaps with the vehicle width center LC, it is easy to suppress the excessive protrusion of each tube 81, 82 in the vehicle width direction. That is, the "brake system in which the ABS modulator 73 is arranged offset to the left or right side with respect to the vehicle width center LC" of the present invention is not limited to the case where the ABS modulator 73 does not overlap with the vehicle width center LC, and also includes the case where a part of the ABS modulator 73 overlaps with the vehicle width center LC.

[0103] like Figure 3 As shown, a portion of the second brake pipe 82 extends rearward at a position higher than the upper surface of the ABS modulator 73, and the first brake pipe 81 extends below a portion of the second brake pipe 82 in a direction intersecting the second brake pipe 82. According to this structure, a sufficient space for the first brake pipe 81 to pass can be ensured below the second brake pipe 82, and the second brake pipe 82 and the first brake pipe 81 can be separated and intersected appropriately.

[0104] like Figure 4As shown, the first brake pipe 81 and the second brake pipe 82 intersect at a position further inward in the vehicle width direction than the outer position of the ABS modulator 73 in the vehicle width direction. Therefore, each pipe 81 and 82 can be arranged so as not to protrude outward from the ABS modulator 73 in the vehicle width direction.

[0105] Furthermore, since the first brake pipe 81 and the second brake pipe 82 intersect at least one of the region overlapping with the ABS modulator 73 and the periphery of the region when viewing the vehicle from the rear, the pipes 81 and 82 can be arranged using the vacant space behind the ABS modulator 73 .

[0106] In addition, the second brake pipe 82 is fixed to the frame 11 via the upstream side pipe retaining portion 92 at a height that overlaps with the ABS modulator 73 in the horizontal direction. Therefore, when the portion of the second brake pipe 82 downstream of the frame fixing position is fixed to the swing arm 16, it is easy to make the portion between the frame fixing position and the downstream portion (equivalent to the front bent portion 82b) function as a deflection absorbing portion that suppresses deflection and movement of the portion of the second brake pipe 82 between the frame 11 and the swing arm 16.

[0107] The second brake pipe 82 has a rear curved portion 82 a curved convexly toward the vehicle rear and a front curved portion 82 b curved convexly toward the vehicle front downstream of the rear curved portion 82 a . The portion between the rear curved portion 82 a and the front curved portion 82 b is fixed to the vehicle frame 11 .

[0108] According to this structure, the second brake pipe 82 forms an S-shape when the vehicle body is viewed from the side due to the rear curved portion 82a and the front curved portion 82b, and it is easy to suppress the second brake pipe 82 from protruding in the vehicle width direction. In addition, it is easy to ensure a space for the first brake pipe 81 to pass between the second brake pipe 82 and the ABS modulator 73 due to the rear curved portion 82a, and it is easy to suppress the bending and movement of the second brake pipe 82 portion between the vehicle frame 11 and the swing arm 16 due to the front curved portion 82b.

[0109] In addition, if Figure 4 As shown, the air cleaner 61 is provided above the second brake pipe 82. According to this structure, the second brake pipe 82 does not bend or move upward, so the capacity of the air cleaner 61 can be increased and the shape can be changed without being affected by the second brake pipe 82.

[0110] In addition, the vehicle frame 11 includes a seat frame 41 for supporting the seat 17 for the passenger, left and right pivot frames 32 located below the seat 17, and a sub-frame 42 extending from the pivot frame 32 to the seat frame 41. Figure 4 As shown, the first brake pipe 81 passes above the sub-frame 42. According to this structure, the space above the sub-frame 42 can be effectively used as a space for the first brake pipe 81.

[0111] The above-mentioned embodiment is one form of the present invention. The present invention is not limited to the above-mentioned embodiment, and the structure of the details and the like may be appropriately changed.

[0112] For example, the ABS modulator 73 is described as being disposed on the right side of the vehicle body, but it may be disposed on the left side of the vehicle body. The ABS modulator 73 may be changed to an appropriate position within the range of being disposed on the outer side in the vehicle width direction.

[0113] In addition, the utility model is applied to Figure 1 The present invention is not limited to the brake pipe wiring structure of a motorcycle shown in the figure, but it can also be applied to the brake pipe wiring structure of any saddle-type vehicle or the like. In addition, the vehicle to which the present invention can be applied is not limited to a two-wheeled vehicle, but can also be a three-wheeled vehicle or a four-wheeled vehicle. In addition, the power unit 12 is not limited to an internal combustion engine, and any driving source such as an electric motor can also be applied.

[0114] [Structure supported by the above-mentioned embodiment]

[0115] The above-mentioned embodiment supports the following structure.

[0116] (Structure 1) A vehicle equipped with a braking system in which an ABS modulator is arranged to one side or the other with respect to the center of the vehicle width, wherein the vehicle has: a master cylinder; a first brake pipe connected from the master cylinder to the ABS modulator; and a second brake pipe connected from the ABS modulator to a braking device at the rear of the vehicle body, and when the vehicle body is observed from the rear view, the first brake pipe and the second brake pipe intersect.

[0117] According to this configuration, the overlapping region of the first brake pipe and the second brake pipe is minimized, and even when the ABS modulator is arranged on the side of the vehicle body, it is easy to suppress excessive protrusion of each pipe in the vehicle width direction.

[0118] (Structure 2) In the vehicle of Structure 1, a portion of the second brake pipe extends rearward at a position higher than the ABS modulator, and the first brake pipe passes under the portion in a direction intersecting the second brake pipe.

[0119] According to this configuration, a sufficient space for the first brake pipe to pass can be ensured below the second brake pipe, and the second brake pipe and the first brake pipe can be appropriately separated and intersected.

[0120] (Configuration 3) In the vehicle of Configuration 1 or 2, the first brake pipe and the second brake pipe intersect at a position on the inside in the vehicle width direction relative to a position on the outside in the vehicle width direction of the ABS modulator.

[0121] According to this configuration, each pipe can be arranged so as not to protrude outward in the vehicle width direction from the ABS modulator.

[0122] (Structure 4) In the vehicle of any one of Structures 1 to 3, when the vehicle body is viewed from the rear, the first brake pipe and the second brake pipe intersect at least one of a region overlapping the ABS modulator and a periphery of the region.

[0123] According to this structure, the two pipes can be arranged by utilizing the space left behind the ABS modulator.

[0124] (Structure 5) In the vehicle of any one of Structures 1 to 4, the second brake pipe is fixed to a frame of the vehicle at a height overlapping with the ABS modulator in the horizontal direction.

[0125] According to this configuration, when the downstream portion of the second brake pipe from the frame fixing position is fixed to the swing arm, the portion between the frame fixing position and the downstream portion can easily function as a deflection absorbing portion for suppressing deflection and movement of the second brake pipe portion between the frame and the swing arm.

[0126] (Structure 6) In the vehicle of Structure 5, the second brake pipe has a rear curved portion that curves convexly toward the rear of the vehicle body and a front curved portion that curves convexly toward the front of the vehicle body downstream of the rear curved portion, and a portion between the rear curved portion and the front curved portion is fixed to the vehicle frame.

[0127] According to this structure, the rear curved portion and the front curved portion make the second brake pipe S-shaped when the vehicle body is viewed from the side, which can easily suppress the second brake pipe from protruding in the vehicle width direction. In addition, the rear curved portion can easily ensure a space for the first brake pipe to pass between the second brake pipe and the ABS modulator.

[0128] (Configuration 7) In the vehicle of Configuration 5 or 6, an air cleaner is provided above the second brake pipe.

[0129] According to this configuration, the second brake pipe does not bend or move upward, and therefore the capacity of the air cleaner can be increased or the shape can be changed without being affected by the second brake pipe.

[0130] (Structure 8) In a vehicle of any one of Structures 1 to 7, the vehicle frame comprises: a seat frame for supporting a seat for an occupant; left and right pivot frames located below the seat; and a sub-frame extending from the pivot frame to the seat frame, and the first brake pipe passes over the top of the sub-frame.

[0131] According to this configuration, the space above the subframe can be effectively utilized as the space for the first brake pipe.
