By the way, the brake operation force by the interlocking brake lever 32 acts on the equalizer 33 via the connecting rod 55, and is distributed from the equalizer 33 to the force for pulling the both

brake cables

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

brake cables

34, 35 different from each other, the two

brake cables

34, 34 are separated at different positions from the connecting position of the connecting rod 55 to the

equalizer

33, 35 are connected to the equalizer 33. That is, in this embodiment, the distance between the connecting position of the connecting rod 55 to the equalizer 33 and the connecting position of the front wheel brake cable 34 to the equalizer 33 is L _F, and the connecting position of the connecting rod 55 to the equalizer 33 and the rear When the distance between the connection positions of the wheel brake cable 35 to the equalizer 33 is L _R , L _F > L _R is set.

The right side wall 57 b of the casing 56 is provided with an initial abutment surface 67 facing the equalizer 33, and the flange portion 33 d of the equalizer 33 can abut on the initial abutment surface 67.

In the equalizer 33, when the interlocking brake lever 32 is not operated, the flange portion 33d abuts on the initial abutment surface 67 of the casing 56, and in accordance with the operation of the interlocking brake lever 32, the flange portion 33d opens from the initial abutment surface 67 Acts to break apart.

The stop switch 68 is in a state where the detector 68a is pushed by the flange portion 33d in a state where the flange portion 33d of the equalizer 33 is in contact with the initial contact surface 67 when the interlocking brake lever 32 is not operated. The interlocking brake lever 32 is released in a state where the pressing force on the detector 68a is released by the flange portion 33d moving away from the initial abutment surface 67 by the operation of the equalizer 33 according to the operation of the interlocking brake lever 32. Detect the non-operation status and operation status of

The casing 56 holds the rear wheel brake cable 35 in a towed state in a non-operating state of the interlocking brake lever 32, but holds the braking force capable of bringing the front wheel brake cable 34 into a non-towed state. Means 70 are provided. The braking force holding means 70 releases the engagement position to engage with the equalizer 33 when the equalizer 33 is in the operating position according to the brake operation of the interlocking brake lever 32, and the non-engagement to the equalizer 33. A braking force holding arm 71 covering the tip of the casing 56 from the outside enabling operation between the engagement positions; an operation lever 72 integrally formed at the tip of the braking force holding arm 71; and an equalizer 33 A return spring 73 resiliently urging the brake force holding arm 71 is provided on the side for releasing the engagement.

As shown in FIGS. 8A and 8B, the braking force holding arm 71 connects the front plate portions of both

arm plate portions

74 and 74 with

arm plate portions

74 and 74 extending in parallel and horizontally so as to sandwich the right side wall 57b. The above-described front cover 59 and an engaging member 77 which is a pin provided over the both

arm plate portions

74, 74 at substantially the middle in the longitudinal direction of the both

arm plate portions

74, 74. Further, support holes 78 are provided in the

arm plate portions

74, 74 at positions overlapping with the right side wall 57b.

In the case 57 of the casing 56, a through hole 57c is provided at the front end of the right side wall 57b. The shaft 79 as a pin is inserted into the support hole 78 and the through hole 57 c of the braking force holding arm 71, whereby the braking force holding arm 71 is rotatably supported by the shaft 79. Further, as shown in FIG. 4, the return spring 73 is provided between the front cover 59 of the braking force holding arm 71 and the right side wall 57 b of the case 57 so as to surround the shaft 79.

On the other hand, in the equalizer 33, of the two

brake cables

34 and 35, the distance from the intermediate connection portion 33m of the connecting rod 55 is smaller, that is, longer on the rear wheel brake cable 35 side from the second connection portion 33f. An extension 33e having a C-shaped cross section extending toward the other end side (forward) of the direction is provided. The extending portion 33e is a pair of

flat plate portions

33a and 33b connected by the connecting portion 33c, which are further extended toward the other end side (forward) of the second connecting portion 33f in the longitudinal direction. As shown in FIG. 10, the engaging member 77 of the braking force holding arm 71 is operated on the extension portion 33e in a state where the equalizer 33 is operated apart from the initial contact surface 67 by the operation of the interlocking brake lever 32. The engaged

portions

80, 80 with which the connector engages are recessed. The deepest portions of the engaged

portions

80, 80 provided recessed are provided closer to the connecting portion 33c than a line connecting the center P1 of the first connecting portion 33r and the center P2 of the second connecting portion 33f.

In the equalizer 33, of the two

brake cables

34 and 35, the distance from the intermediate connection portion 33m of the connecting rod 55 is longer, ie, longer on the front wheel brake cable 34 side from the first connection portion 33r. A second extension 33g is provided extending toward one end side (rear) of the direction. The second extending portion 33g is formed by extending the upper flat plate portion 33a of the pair of

flat plate portions

33a and 33b further toward the one end side (rearward) in the longitudinal direction than the first connection portion 33r. 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 direction. By forming the curved portion 33h having a large radius of curvature, it is possible to prevent the equalizer 33 from being easily caught in the cable insertion portion 57d when the equalizer 33 is miniaturized.

The operating lever 72 is formed integrally with the braking force holding arm 71 so as to extend in substantially the same direction as the interlocking brake lever 32. The control lever 72 is also extended outward from an opening provided in the handle cover 53 so that the grip 46 at the left end of the steering handlebar 45 and the interlocking brake lever 32 project.

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

When operating the braking force holding means 70, the operating lever 72 is turned in a state where the interlocking brake lever 32 is operated. Then, as shown in FIG. 10, the brake force holding arm 71 moves from the non-engagement position to the engagement position against the spring force of the return spring 73, and moves to the actuated position. The engaging member 77 of the braking force holding arm 71 engages with the engaging

portions

80, 80. Therefore, when the operating force of the interlocking brake lever 32 is released, the equalizer 33 operates the rear wheel brake cable 35 to the traction operating state, but operates the braking force holding position to the front wheel brake cable 34 not to the traction state. become. Only the rear wheel brake B _R is activated in this state, the front wheel brake B _F becomes inoperative state, such braking force retaining state is detected by the stop switch 68. That is, at the time of holding the braking force, the hydraulic pressure does not act on rubber components such as hoses and seals which are components of the hydraulic type front wheel brake _BF , and the life of the rubber components can be increased.

Moreover, the engaged

portions

80, 80 are brake cables for which the distance from the connecting portion of the interlocking brake lever 32 is smaller among the front wheel brake cable 34 and the rear wheel brake cable 35, that is, the rear wheel brake cable 35. The equalizer 33 is provided on the side. Therefore, the engaging member 77 of the braking force holding means 70 can be engaged with the equalizer 33 on the side which operates relatively largely according to the operation of the interlocking brake lever 32. As a result, the amount of operation of the interlocking brake lever 32 when operating the braking force holding means 70 can be made relatively small.

At this time, in the extension portion 33e, one side (one side in the width direction) of two

flat plate portions

33a and 33b arranged in parallel is connected by the connecting portion 33c, and the engagement member 77 is engaged with the engaged portion 80, An imaginary line L1 parallel to the rear wheel brake cable 35 in a state of being engaged with the wheel 80 and passing through the engaged

portions

80, 80 is formed to intersect the connecting portion 33c. Therefore, the reaction force of the rear wheel brake cable 35 acting on the engaged

portions

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

In order to release such a braking force holding state, the interlocking brake lever 32 may be slightly rotated. Then, the brake force holding arm 71 is moved from the engaged position to the non-engaged position by the spring force of the return spring 73, and the engagement of the brake force holding arm 71 with the equalizer 33 is released. Thus, by returning the interlocking brake lever 32 to the original position, the equalizer 33 returns to the inoperative position, and the rear wheel brake _BR is put into a rest state.

As described above, in the present embodiment, the equalizer 33 extends from the second connection portion 33f to which the rear wheel brake cable 35 is connected to the C-shaped extending portion 33e extending further toward the other end in the longitudinal direction. In the extension 33e, an engaged portion 80 is formed, with which the engaging member 77 of the brake force holding arm 71 is engaged. Therefore, even if it is compact, high rigidity can be exhibited and weight reduction can be achieved while maintaining the function as the equalizer 33.

Further, since the case 57 accommodating the equalizer 33 is integrally formed with the holder 47 supporting the interlocking brake lever 32 with respect to the steering handlebar 45, the number of parts can be reduced.

In addition, the front and rear interlocking brake device 10 for a motorcycle further includes a front cover 59 that covers the other end side of the extension 33e of the equalizer 33 in the longitudinal direction, and the front cover 59 is provided with an engaging member 77 of the braking force holding arm 71. The number of parts can be further reduced.

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

In the equalizer 33, one side of two

flat plate portions

33a and 33b arranged in parallel is connected by the connecting portion 33c, and at least one of the two

flat plate portions

33a and 33b in which the connecting portion 33c is not provided. Since the flange portion 33d is formed on the other side, the rigidity of the open portion can be enhanced while achieving weight reduction.

Further, in the extension portion 33e of the equalizer 33, one side of two

flat plate portions

33a and 33b arranged in parallel is connected by the connecting portion 33c, and the engaging member 77 is engaged with the engaged portion 80. A virtual line L1 passing through the engaged portion 80 is parallel to the rear wheel brake cable 35 in the on state, and intersects the connecting portion 33c. Accordingly, the reaction force of the rear wheel brake cable 35 acting on the engaged portion 80 can be supported by the connecting portion 33 c.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, It can change suitably.
For example, the connection between the interlocking brake lever 32 and the equalizer 33 may be connected indirectly via the connecting rod 55, or may be connected directly without using the connecting rod 55.
Also, the shape of the equalizer 33 can be changed as appropriate.
