[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6585858 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional interlocking brake devices, the interlocking brake lines are routed so that they bulge forward around the handlebars, which requires space in the front-to-rear direction to arrange the connecting cables, limiting how compact the vehicle can be.

[0005] SUMMARY OF THE INVENTION The present invention aims to reduce the size of a saddle-ride type vehicle equipped with a linked brake device that links the front and rear brakes by reducing the space required in the front-to-rear direction for arranging connecting cables. [Means for solving the problem]

[0006] A saddle-ride type vehicle according to a first aspect of the present invention includes a steering handlebar (34) having a length in the vehicle width direction and both ends in the vehicle width direction bent rearward in a plan view, a pair of left and right brake levers (60, 80) held by the handlebar (34), electrical components (15) arranged in front of the handlebar (34), a master cylinder (65) supported at a location near one of the left and right ends of the handlebar (34) and having a cylinder body (66) arranged parallel to the handlebar (34), the master cylinder (65) generating hydraulic pressure in response to an operating force of a first brake lever (60) of the pair of brake levers (60, 80), and a second brake lever (80) of the other of the pair of brake levers (60, 80) and the master cylinder ( a connecting cable (90) connected to the master cylinder (65) and disposed between the handlebar (34) and the electrical component (15), for transmitting the operating force of the second brake lever (80) to the master cylinder (65); and a holder (95) for holding the end of the connecting cable (90) on the master cylinder (65) side, wherein the connecting cable (90) has a coupling part (93) fixed to the holder (95), and a central axis (C1) of the coupling part (93) is inclined with respect to the axis (C2) of the cylinder body (66), and as it moves away from the cylinder body (66) toward the second brake lever (80) in the vehicle width direction, it moves away rearward from the axis (C2) of the cylinder body (66) in a plan view of the vehicle.

[0007] According to the first aspect, compared to when the central axis of the connecting cable's joint is arranged parallel to the handlebar and the cylinder body, the connecting cable is arranged closer to the handlebar, which extends rearward as it moves outward in the vehicle width direction. This prevents the connecting cable from bulging forward, thereby reducing interference of the connecting cable with electrical components arranged in front of the handlebar and reducing the space required for arranging the connecting cable in the fore-and-aft direction, making it possible to make the vehicle more compact.

[0008] A saddle-ride type vehicle according to a second aspect of the present invention is the saddle-ride type vehicle according to the first aspect, further comprising: a brake line (54) extending from the master cylinder (65) toward the front wheel brake (53) and having a connecting member (75) fastened to the master cylinder (65); and a fastening portion (68) fastening the connecting member (75) to the master cylinder (65), wherein the connecting cable (90) has an extension portion (90a) extending from the holder (95) toward the second brake lever (80), and the extension portion (90a) may be disposed between a front end of the fastening portion (68) and a rear end of the end of the extension portion (90a) on the holder (95) side in the fore-and-aft direction when the vehicle is viewed from above.

[0009] According to the second aspect, the connecting cable can be routed substantially parallel to the vehicle width direction so as not to bulge forward, thereby making it possible to reduce the size of the vehicle.

[0010] A saddle-ride type vehicle according to a third aspect of the present invention is the saddle-ride type vehicle according to the first or second aspect, wherein the joint portion (93) overlaps the connecting member (75) in a plan view of the vehicle, and the brake line (54) extends rearward from the master cylinder (65) and passes behind the connecting cable (90).

[0011] According to the third aspect, the connecting member and the connecting portion are arranged so as to overlap each other in a plan view of the vehicle, thereby making it possible to compact the space required for routing the connecting cable and brake line in the fore-and-aft direction of the vehicle. Furthermore, by arranging the connecting member above the connecting portion and extending the brake line rearward from the master cylinder, it is possible to ensure tool access to the connecting portion of the connecting cable.

[0012] A saddle-ride type vehicle according to a fourth aspect of the present invention is a saddle-ride type vehicle according to any one of the first to third aspects, wherein the brake line (54) is arranged so as to follow the front end edge (34a) of the handlebar (34) in at least one of a plan view of the vehicle or a side view of the vehicle, and at least a portion of the connecting member (75) overlaps the front end edge (34a) of the handlebar (34) in a plan view of the vehicle.

[0013] According to the fourth aspect, the brake line is prevented from bulging rearward and being routed further rearward than the handlebar, and the handlebar and connecting member are arranged so that they overlap each other when viewed from above the vehicle, allowing the handlebar and connecting member to be arranged compactly in the fore-and-aft direction of the vehicle.

[0014] A saddle-ride type vehicle according to a fifth aspect of the present invention is a saddle-ride type vehicle according to any one of the first to fourth aspects, further comprising a steering shaft (33) that is connected to the handlebar (34) so ​​as not to be displaceable relative to the handlebar (34) and that is rotatably supported on a head pipe (21) of a body frame (4), and the connecting cable (90) may intersect with the brake line (54) within a width (W) of the steering shaft (33) when viewed from the front of the vehicle.

[0015] According to the fifth aspect, it is possible to prevent the brake line and the connecting cable from interfering with the electrical components arranged in front of the handlebars when steering.

[0016] A saddle-ride type vehicle according to a sixth aspect of the present invention is a saddle-ride type vehicle according to any one of the first to fifth aspects, further comprising a fastening portion (68) that fastens the connecting member (75) to the master cylinder (65), and the handlebar (34) has a held portion (34b) that is held by the master cylinder (65), and the centers of the fastening portion (68), the connecting portion (93), and the held portion (34b) may be located at the vertices of an acute triangle (T) when viewed from the side of the vehicle.

[0017] According to the sixth aspect, by arranging the coupling portion rearward of the fastening portion, it is possible to prevent the connecting cable from bulging forward, thereby reducing the longitudinal space required for arranging the connecting cable and enabling a more compact vehicle. Furthermore, by arranging the fastening portion, coupling portion, and the retained portion of the handlebar at the apexes of an acute-angled triangle in side view, it is possible to prevent the distance between each portion from increasing, allowing the connecting cable, brake line, and handlebar to be arranged compactly in the longitudinal direction of the vehicle. If the fastening portion, coupling portion, and the retained portion of the handlebar were arranged so that the apex where the coupling portion is located forms an obtuse angle in side view, at least one of the distance between the coupling portion and the fastening portion and the distance between the coupling portion and the retained portion of the handlebar would increase, making it difficult to achieve the above-mentioned effects. Therefore, it is preferable to arrange the fastening portion, coupling portion, and the retained portion of the handlebar at the apexes of an acute-angled triangle in side view. [Effects of the Invention]

[0018] According to the present invention, in a saddle-ride type vehicle equipped with a linked brake device that links front and rear brakes, the space in the front-to-rear direction required for arranging a connecting cable can be reduced, thereby making the vehicle more compact.

The inner cable 92 is pulled to the left when it receives the operating force of the left brake lever 80. When the inner cable 92 is pulled to the left, it presses against the piston of the master cylinder 65, generating brake fluid pressure inside the master cylinder 65 and actuating the front wheel brake 53.

[0046] As shown in FIG. 6 , the connecting cable 90 is disposed between the handlebar 34 and the headlight 15. Here, the portion of the connecting cable 90 extending from the holder 95 toward the left brake lever 80 is referred to as the bridging portion 90a. As shown in FIG. 5 , the bridging portion 90a is disposed between the front end of the banjo bolt 68 and the rear end of the holder 95-side end of the bridging portion 90a in the front-to-rear direction in a plan view. In this embodiment, the front end of the banjo bolt 68 coincides with the front end of the head of the banjo bolt 68. In this embodiment, the rear end of the holder 95-side end of the bridging portion 90a coincides with the rear end of the head of the connecting bolt 93. As in this embodiment, it is desirable for the bridging portion 90a to be disposed between the rear end of the head of the banjo bolt 68 and the rear end of the connecting bolt 93, but this is not limitative as long as it is disposed within the above-mentioned range. The position of the front end of the banjo bolt 68 in the front-to-rear direction is indicated by an imaginary line L1 in FIG. 5 . The position of the rear end of the connecting bolt 93 in the front-to-rear direction is indicated by an imaginary line L2 in FIG. 5 . Furthermore, the connecting cable 90 extends along an imaginary straight line L3 that is parallel to the vehicle width direction in a plan view, and is routed approximately parallel to the vehicle width direction. In a plan view, the imaginary straight line L3 passes through the center of the end of the installation portion 90a on the holder 95 side. For example, a portion of the connecting cable 90 located between both ends of the outer cable 91 extends along the imaginary straight line L3. Furthermore, the connecting cable 90 overlaps the entire imaginary line segment S that extends in the vehicle width direction in a plan view. In a plan view, the imaginary line segment S overlaps the middle portion 35 of the handlebar 34 in the front-to-rear direction. In a plan view, the imaginary line segment S is located in front of the middle portion 35 of the handlebar 34. In the vehicle width direction, both ends of the imaginary line segment S coincide with both ends 35a of the middle portion 35 of the handlebar 34.

[0047] It is desirable that the imaginary line segment S be located between the front end of the connecting portion 97 of the holder 95 and the rear end of the banjo joint 75 in a plan view. More desirably, the imaginary line segment S is located between the front end and rear end of the banjo joint 75 in the front-to-rear direction in a plan view, but is not limited to this configuration.

[0048] 4 and 8, the front brake line 54 passes behind the connecting cable 90. Specifically, in a front view, the brake hose 70 passes behind the connecting cable 90. The connecting cable 90 intersects with the front brake line 54 within the width W of the steering stem 33 in a front view.

[0049] 7, in a side view, the centers of the banjo bolt 68, the connecting bolt 93 of the outer cable 91, and the held portion 34b of the handlebar 34 held by the right lever holder 63 are located at the vertices of an acute triangle T. The centers are defined by the ends of the central axes of the respective members on the inner side in the vehicle width direction.

[0050] As described above, motorcycle 1 of this embodiment includes master cylinder 65 having cylinder body 66 arranged parallel to handlebar 34, connecting cable 90 connected to left brake lever 80 and master cylinder 65 and arranged between handlebar 34 and headlight 15 to transmit the operating force of left brake lever 80 to master cylinder 65, and holder 95 for holding the end of connecting cable 90 on the master cylinder 65 side. Connecting cable 90 has connecting bolt 93 fixed to holder 95. Central axis C1 of connecting bolt 93 is inclined with respect to axis C2 of cylinder body 66, and moves further rearward from axis C2 of cylinder body 66 in plan view as it moves away from cylinder body 66 toward left brake lever 80 in the vehicle width direction. With this configuration, connecting cable 90 is arranged closer to handlebar 34, which extends rearward as it moves outward in the vehicle width direction, compared to when the central axis of the connecting bolt is arranged parallel to handlebar 34 and cylinder body 66. This prevents the connecting cable 90 from bulging forward, thereby reducing the space required in the front-to-rear direction for arranging the connecting cable 90 and suppressing interference of the connecting cable 90 with electrical components, including the headlight 15, arranged in front of the handlebar 34. Therefore, it is possible to arrange the connecting cable 90 and the electrical components in front of it in a compact manner in the front-to-rear direction while ensuring clearance between the connecting cable 90 and the electrical components in front of it, thereby enabling the vehicle to be made more compact.

[0051] In particular, it is necessary to ensure sufficient space around the headlight 15 to allow for heat dissipation. Furthermore, in headlights that use LEDs as their light source, there is a limit to how small the headlight itself can be, which means that interference between the connecting cable and the headlight is likely to occur. Therefore, in this embodiment, since the headlight 15 with an LED light source is located in front of the handlebar 34, it is effective to position the connecting cable 90 so that it does not bulge forward.

[0052] The motorcycle 1 includes a front brake line 54 extending from a master cylinder 65 toward the front wheel brake 53, and a banjo bolt 68 that fastens a banjo joint 75 of the front brake line 54 to the master cylinder 65. The connecting cable 90 has a bridging portion 90a that extends from a holder 95 toward the left brake lever 80. The bridging portion 90a is disposed between the rear end of the banjo bolt 68 and the rear end of the holder 95-side end of the bridging portion 90a in the front-to-rear direction in a plan view. This configuration allows the connecting cable 90 to be routed approximately parallel to the vehicle width direction without bulging forward. Therefore, the above-described effects can be achieved.

[0053] The connection bolt 93 of the connecting cable 90 overlaps the banjo joint 75 in a plan view. The front brake line 54 extends rearward from the master cylinder 65 and passes behind the connecting cable 90. With this configuration, the banjo joint 75 and the connection bolt 93 are arranged so as to overlap each other in a plan view, thereby making it possible to compact the space in the front-to-rear direction required for routing the connecting cable 90 and the front brake line 54. Furthermore, by arranging the banjo joint 75 above the connection bolt 93 and then extending the front brake line 54 rearward from the master cylinder 65, a space facing the connection bolt 93 can be provided in a range R extending from forward to downward of the connection bolt 93 in a side view as shown in FIG. 6, and this makes it possible to ensure access to the connection bolt 93 of the connecting cable 90 with a tool such as a wrench.

[0054] The front brake line 54 is arranged so as to follow the front end edge 34a of the handlebar 34 in plan and side views. At least a portion of the banjo joint 75 overlaps the front end edge 34a of the handlebar 34 in plan view. This configuration prevents the front brake line 54 from bulging rearward and being routed rearward of the handlebar 34, while the handlebar 34 and the banjo joint 75 are arranged so as to overlap each other in plan view, allowing the handlebar and the banjo joint 75 to be arranged compactly in the front-to-rear direction.

[0055] Motorcycle 1 includes a steering stem 33 that is connected to handlebar 34 so as not to be displaceable relative to the handlebar, and that is rotatably supported on head pipe 21 of body frame 4. Connecting cable 90 intersects with front brake line 54 within width W of steering stem 33 in a front view. This configuration prevents front brake line 54 and connecting cable 90 from interfering with electrical components arranged in front of handlebar 34 when steering.

[0056] The handlebar 34 has a retained portion 34b that is retained by the master cylinder 65. In a side view, the centers of the banjo bolt 68, the connecting bolt 93, and the retained portion 34b are located at the vertices of an acute triangle T. With this configuration, by locating the connecting bolt 93 rearward of the banjo bolt 68, it is possible to prevent the connecting cable 90 from being routed so that it bulges forward, and it is possible to downsize the vehicle by reducing the space required in the fore-and-aft direction for locating the connecting cable 90. Furthermore, by locating the banjo bolt 68, the connecting bolt 93, and the retained portion 34b of the handlebar 34 at the vertices of the acute triangle T in a side view, it is possible to prevent the distance between each part from increasing, and it is possible to locate the connecting cable 90, front brake line 54, and handlebar 34 in a compact manner in the fore-and-aft direction. If the banjo bolt 68, connection bolt 93, and held portion 34b of the handlebar 34 were arranged so that the apex at which the connection bolt 93 is located forms an obtuse angle in side view, at least one of the distance between the connection bolt 93 and the banjo bolt 68 and the distance between the connection bolt 93 and the held portion 34b of the handlebar 34 would increase, making it difficult to achieve the above-mentioned effects, so it is desirable to arrange the banjo bolt 68, connection bolt 93, and held portion 34b of the handlebar 34 at the apex of an acute-angled triangle in side view.

[0057] The present invention is not limited to the above-described embodiment explained with reference to the drawings, and various modifications are possible within the technical scope of the present invention. For example, in the above embodiment, as shown in FIG. 9, the central axis C1 of the connecting bolt 93 of the connecting cable 90 is inclined with respect to the vehicle width direction, but this configuration is not limited to this, and for example, the central axis of the connecting bolt may extend parallel to the vehicle width direction.

[0058] In the above embodiment, the arm portion 77 of the banjo joint 75 extends rearward and upward from the annular portion 76, but the arm portion of the banjo joint may extend rearward or rearward and downward from the annular portion. Even in this case, the above-described effects can be achieved as long as the front brake line passes behind the connecting cable 90. However, the arrangement of the front brake line relative to the connecting cable 90 can be changed as appropriate.

[0059] In the above embodiment, the upper portion 71 of the brake hose 70 is arranged so as to follow the front edge 34a of the handlebar 34 in both a plan view and a side view, but is not limited to this configuration. The above-described effects can be achieved as long as the brake hose is arranged so as to follow the front edge 34a of the handlebar 34 and overlap the front edge 34a of the handlebar 34 in at least one of a plan view and a side view.

[0060] In the above embodiment, the connecting cable 90 intersects with the front brake line 54 within the width W of the steering stem 33 in a front view, but this configuration is not limiting. In other words, the connecting cable and the front brake line may intersect with each other outside the width of the steering stem 33 in a front view.

[0061] In the above embodiment, the electrical component arranged in front of the middle part 35 of the handlebar 34 is the headlight 15, but the electrical component arranged in front of the middle part of the handlebar may also be a lighting device including a headlight, a meter device, etc.

[0062] In addition, the components in the above-described embodiments can be replaced with well-known components as appropriate, without departing from the spirit of the present invention. [Explanation of symbols]
