The longitudinal middle portion of the steering handle bar 45 is covered with a handle cover 53 made of synthetic resin. The grip portion 46 at the left end of the steering handle bar 45 and the interlock brake lever 32 protrude outward from an opening provided at the left side of the handle cover 53.

A housing 56 that houses the balancer 33 so as to be operable is fixedly disposed at a position adjacent to the inside of the interlock brake lever 32 in the longitudinal direction of the steering handle lever 45 and at a position forward of the steering handle lever 45. Referring also to fig. 5, 7A and 7B, the housing 56 includes: a box-shaped case 57 integrally provided on the bracket 47 and opened to the front side, the left side, and the bottom side; a bottom cover 58 coupled to the case 57 so as to cover the bottom opening 57ab of the case 57; and a front cover 59 rotatably coupled to the housing 57 so as to cover the front opening 57af of the housing 57. The braking force holding arm 71, which will be described later, is integrally formed with the front cover 59.

As shown in fig. 3, one end of the connecting rod 55 is connected to the base end of the interlocking brake lever 32 by a screw 60, and the connecting rod 55 is inserted into the housing 56 from the left side opening 57as of the housing 56.

As shown in fig. 6A to 6D, the balancer 33 has a substantially rectangular shape, and one side in the short side direction of a pair of

flat plate portions

33a, 33b extending parallel to each other and horizontally is connected at two locations by a connecting portion 33C, and the connecting portion 33C extends in a direction orthogonal to the

flat plate portions

33a, 33b and has a C-shaped cross section. Further, a flange portion 33d that is folded back in a direction away from the other flat plate portion 33a and is substantially orthogonal to the flat plate portion 33a is provided on the other side in the short-side direction of one flat plate portion 33b of the pair of

flat plate portions

33a, 33 b. The flange portion 33d is provided so as to be able to abut on an initial abutment surface 67 described later.

The pair of

flat plate portions

33a and 33b are provided with a first connecting portion 33r for connecting the front wheel brake cable 34, an intermediate connecting portion 33m for connecting the connecting link 55, and a second connecting portion 33f for connecting the rear wheel brake cable 35 in this order from one end in the longitudinal direction.

As shown in fig. 3, the balancer 33 configured as described above is disposed in the housing 56 such that the short-side direction is substantially oriented in the left-right direction and the long-side direction is substantially oriented in the front-rear direction, the flat plate portion 33a is located above and the flat plate portion 33b is located below. More specifically, one longitudinal end side of the first connection portion 33r, which is provided with the front wheel brake cable 34 connected thereto, is directed rearward; the other end side in the longitudinal direction of the second connection portion 33f to which the rear wheel brake cable 35 is connected is oriented forward; one end side in the short side direction where the connection portion 33c is provided faces leftward; and the other end side in the short side direction, at which the flange portion 33d is provided, is directed rightward, and the flange portion 33d extends further downward from the flat plate portion 33b located below.

The other end of the link 55 is inserted between the pair of

flat plate portions

33a and 33b from between the coupling portions 33c and is coupled to the balancer 33 via a coupling screw 62 passing through the intermediate coupling portion 33 m.

Therefore, in order to accommodate the balancer 33, which is long in the horizontal direction, so that the balancer 33 can operate, the housing 56 is formed in a laterally long shape in which the length in the front-rear left-right direction is longer than the length in the up-down direction of the motorcycle.

Further, the

outer cables

34a, 35a of the front wheel brake cable 34 and the rear wheel brake cable 35 are fixed in parallel to each other at positions spaced apart in the front-rear direction of the right side wall 57b in the case 57 of the outer case 56. That is, the outer cable 34a is fixed to the rear side of the right side wall 57b of the housing 57 at one end portion of the front wheel brake cable 34 through which the inner cable 34b is inserted so as to be movable within the outer cable 34 a. The inner cable 34b protruding from the outer cable 34a is inserted into the housing 56 through the cable insertion portion 57d, and the locking piece 64 provided at the end of the inner cable 34b is coupled to the first coupling portion 33r of the balancer 33.

Further, the outer cable 35a is fixed to the front of the right side wall 57b of the housing 57 at one end portion of the rear wheel brake cable 35 through which the inner cable 35b is inserted so as to be movable in the outer cable 35 a. The inner cable 35b protruding from the outer cable 35a is inserted into the housing 56 through the cable insertion portion 57d, and the locking piece 65 provided at the end of the inner cable 35b is coupled to the second coupling portion 33f of the balancer 33.

Further, the brake operating force generated by the interlock brake lever 32 acts on the equalizer 33 via the coupling lever 55, and the force that pulls the two

brake cables

34, 35 is distributed from the equalizer 33. However, in order to make the forces distributed from the balancer 33 to the two

brake cables

34, 35 different from each other, the two

brake cables

34, 35 are coupled to the balancer 33 at positions where the distances from the coupling position where the coupling rod 55 is coupled to the balancer 33 are different from each other. That is, in this embodiment, the distance between the coupling position at which the coupling lever 55 is coupled to the balancer 33 and the coupling position at which the front wheel brake cable 34 is coupled to the balancer 33 is L_FL is a distance between a coupling position where the coupling rod 55 is coupled to the balancer 33 and a coupling position where the rear wheel brake cable 35 is coupled to the balancer 33_RIs set to L_F＞L_R。

An initial abutment surface 67 opposed to the balancer 33 is provided on the right side wall 57b in the housing 56, and the flange portion 33d of the balancer 33 can abut against the initial abutment surface 67.

The balancer 33 operates as follows: when the interlock brake lever 32 is not operated, the flange portion 33d abuts against the initial abutment surface 67 of the housing 56, and the flange portion 33d is separated from the initial abutment surface 67 in accordance with the operation of the interlock brake lever 32.

In addition, a stop switch 68 is mounted on the housing 56 such that the detector 68a faces the initial abutment surface 67. The stop switch 68 detects a non-operation state and an operation state of the interlock brake lever 32 by a state in which the flange portion 33d of the balancer 33 is pressed against the detector 68a in a state in which the flange portion 33d abuts against the initial abutment surface 67 when the interlock brake lever 32 is not operated; and a state in which the flange portion 33d is separated from the initial contact surface 67 by operation of the balancer 33 in accordance with operation of the interlock brake lever 32, thereby releasing the pressing force to the detector 68 a.

The housing 56 is provided with a braking force holding mechanism 70, and the braking force holding mechanism 70 can hold the rear wheel brake cable 35 in a traction operation state and can put the front wheel brake cable 34 in a non-traction operation state in a non-operation state of the interlock brake lever 32. The braking force holding mechanism 70 includes: a braking force holding arm 71 that is capable of operating between an engagement position where the balancer 33 is engaged and a non-engagement position where the balancer 33 is disengaged when the balancer 33 is in the operating position by a brake operation of the interlock brake lever 32, and covers the front end portion of the housing 56 from the outside; an operation lever 72 integrally formed at a distal end portion of the braking force retaining arm 71; and a return spring 73 that elastically biases the braking force holding arm 71 toward the side where the engagement with the balancer 33 is released.

As shown in fig. 8A and 8B, the braking force holding arm 71 includes

arm plate portions

74, 74 extending horizontally in parallel to each other with the right side wall 57B interposed therebetween, the front cover 59 connecting front surface portions of the two arm plate portions 74, and an engaging member 77 that is a pin provided between the two

arm plate portions

74, 74 at a substantially middle portion in the longitudinal direction of the two

arm plate portions

74, 74. Further, a support hole 78 is provided in the

arm plate portions

74, 74 at a position overlapping the right side wall 57 b.

In the case 57 of the housing 56, a through hole 57c is provided at the front end of the right side wall 57 b. The shaft portion 79 as a pin is inserted through the support hole 78 and the through hole 57c of the braking force holding arm 71, and the braking force holding arm 71 is rotatably supported by the shaft portion 79. As shown in fig. 4, the return spring 73 is provided around the shaft portion 79 between the front cover 59 of the braking force holding arm 71 and the right side wall 57b of the housing 57.

On the other hand, in the balancer 33, the extension 33e having a C-shaped cross section is provided on the rear wheel brake cable 35 side, which is the side of the two

brake cables

34 and 35 where the distance from the intermediate connection portion 33m of the connecting rod 55 is small, and extends from the second connection portion 33f toward the other end side (front) in the longitudinal direction. The extending portion 33e is formed by extending the pair of

flat plate portions

33a and 33b connected by the connecting portion 33c further toward the other end side (front) in the longitudinal direction than the second connecting portion 33 f.

Engaged portions

80, 80 are provided in a recessed manner in the extending portion 33e, and the engaged

portions

80, 80 are engaged with the engaging member 77 of the braking force holding arm 71 in a state where the balancer 33 is operated away from the initial contact surface 67 by the operation of the linking brake lever 32 as shown in fig. 10. The deepest portions of the engaged

portions

80 and 80 provided in the recessed manner are provided on the side of the coupling portion 33c with respect to a line connecting the center P1 of the first coupling portion 33r and the center P2 of the second coupling portion 33 f.

Further, in the balancer 33, a second extending portion 33g extending from the first connecting portion 33r further toward one end side in the longitudinal direction (rearward) is provided on the front wheel brake cable 34 side, which is the side of the two

brake cables

34 and 35 where the distance from the intermediate connecting portion 33m of the connecting rod 55 is large. The second extending portion 33g is formed by extending the upper flat plate portion 33a of the pair of

flat plate portions

33a, 33b further toward one end side (rear) in the longitudinal direction than the first connecting portion 33 r. The second extending portion 33g is provided with a curved portion 33h having a large radius of curvature on the surface on the other end side (right side) in the short side direction. By forming the curved portion 33h having a large radius of curvature, it is possible to prevent the equalizer 33 from easily biting into the cable insertion portion 57d when the equalizer 33 is downsized.

The operating lever 72 is formed to extend in substantially the same direction as the interlock brake lever 32 integrally with the braking force retaining arm 71. The operating lever 72 also extends outward from an opening portion provided in the handle cover 53 so as to project the grip portion 46 of the left end portion of the steering handle lever 45 and the interlock brake lever 32.

That is, the front opening 57af of the case 57 located on the other end side (front side) in the longitudinal direction of the extending portion 33e is covered with the front cover 59, and the engaging member 77 is provided on the front cover 59. Further, the operation lever 72 for operating the engaging member 77 is integrally provided on the front cover 59.

When the braking force holding mechanism 70 is operated, the operating lever 72 is pivotally operated in a state where the interlocking brake lever 32 is operated. As a result, as shown in fig. 10, the braking force holding arm 71 moves from the non-engagement position to the engagement position against the spring force of the return spring 73, and the engagement member 77 of the braking force holding arm 71 engages with the engaged

portions

80, 80 of the balancer 33 that has moved to the operating position. Therefore, when the operating force of the linking brake lever 32 is released, the equalizer 33 operates to a braking force holding position where the rear wheel brake cable 35 is in a traction operation state and the front wheel brake cable 34 is in a non-traction state. In this state, only the rear wheel brake B_ROperating, front wheel brake B_FThe brake force holding state is detected by the stop switch 68 when the vehicle is in the non-operating state. That is, when the braking force is maintained, the hydraulic pressure is not applied to the front wheel brake B as the hydraulic pressure type_FThe rubber member(s) such as the hose and the seal can be increased in life.

The engaged

portions

80, 80 are provided on the balancer 33 on the side of the rear wheel brake cable 35, which is the brake cable having a small distance from the coupling portion of the interlock brake lever 32, of the front wheel brake cable 34 and the rear wheel brake cable 35. Therefore, the engagement member 77 of the braking force holding mechanism 70 can be engaged with the balancer 33 on the side that is relatively largely operated by the operation of the interlock brake lever 32. This makes it possible to relatively reduce the amount of operation of the interlock brake lever 32 when the braking force holding mechanism 70 is actuated.

At this time, the extension portion 33e is formed as follows: one side (one side in the short-side direction) of the 2

flat plate portions

33a and 33b arranged in parallel is connected by a connecting portion 33c, and is parallel to the rear wheel brake cable 35 in a state where the engaging member 77 is engaged with the engaged

portions

80 and 80, and intersects with the connecting portion 33c through an imaginary line L1 of the engaged

portions

80 and 80. Therefore, the reaction force of the rear wheel brake cable 35 acting on the engaged

portions

80, 80 can be supported by the coupling portion 33 c.

To release the braking force holding state, the interlock brake lever 32 may be slightly rotated. In this way, the braking force holding arm 71 is moved from the engagement position to the non-engagement position by the spring force of the return spring 73, and the engagement between the braking force holding arm 71 and the balancer 33 is released. In this way, by returning the interlock brake lever 32 to the original state, the balancer 33 is returned to the non-operating position, and the rear wheel brake B is operated_RThe system is brought into a stopped state.

As described above, in the present embodiment, the balancer 33 includes the extended portion 33e having a C-shaped cross section that extends further toward the other end side in the longitudinal direction from the second connection portion 33f that connects the rear wheel brake cable 35, and the engaged portion 80 that the engaging member 77 of the braking force holding arm 71 engages is formed in the extended portion 33 e. Therefore, even if the balancer 33 is compact, it can exhibit high rigidity and can be reduced in weight while maintaining the function as the balancer 33.

Further, since the housing 57 accommodating the balancer 33 is formed integrally with the bracket 47 supporting the interlock brake lever 32 to the steering handle lever 45, the number of components can be reduced.

Further, the front-rear interlocking brake device 10 for a motorcycle further includes the front cover 59 covering the other end side in the longitudinal direction of the extending portion 33e of the balancer 33, and the engaging member 77 of the braking force retaining arm 71 is provided on the front cover 59, so that the number of components can be further reduced.

Further, since the operation lever 72 for operating the engaging member 77 is integrally provided on the front cover 59, the number of components can be further reduced.

In the balancer 33, one side of the 2

flat plate portions

33a and 33b arranged in parallel is connected by the connecting portion 33c, and the flange portion 33d is formed on the other side of at least one of the 2

flat plate portions

33a and 33b where the connecting portion 33c is not provided.

One side of the 2

flat plate portions

33a and 33b arranged in parallel in the extending portion 33e of the balancer 33 is connected by the connecting portion 33c, and the rear wheel brake cable 35 in a state where the engaging member 77 is engaged with the engaged portion 80 is parallel to and intersects with the connecting portion 33c through an imaginary line L1 passing through the engaged portion 80. Therefore, the reaction force of the rear wheel brake cable 35 acting on the engaged portion 80 can be supported by the coupling portion 33 c.

While one embodiment of the present invention has been described above, the present invention is not limited to this, and can be modified as appropriate.

For example, the linkage brake lever 32 and the balancer 33 may be indirectly connected via the link 55, or may be directly connected without via the link 55.

In addition, the shape of the balancer 33 can be changed as appropriate.
