Problems solved by technology

As a solution, it is conceivable to change the ratio of the brake pedal operation amount to the rear wheel brake workload, but if the brake pedal operation amount is not changed and the ratio is lowered, the stroke of the rear wheel brake will sometimes be increased, which will cause the rear wheel brake to malfunction. The clearance becomes larger
[0007] In this way, in a linked brake using a drum brake on the rear brake, the play of the rear brake may sometimes become large

Embodiment

[0028] Embodiments of the present invention will be described based on the drawings.

[0029] like figure 1 As shown, in the front portion of a two-wheeled motorcycle 10 as a form of saddle-riding vehicles, a front fork 11 extends obliquely forward and downward, and a front wheel 13 is mounted on the lower end of the front fork 11 so that it can rotate freely. , a front wheel brake 15 is provided on the front wheel 13 . The front wheel brake 15 applies a braking force (braking force) to the front wheel 13 .

[0030] In addition, at the rear of the motorcycle 10, starting from the vehicle body frame 20, a rocker arm 12 extends toward the rear of the vehicle and can swing freely. The rear end of the rocker arm 12 pivotally supports the rear wheel 14 in a rotatable manner. Rear wheel brakes 16 are provided on the rear wheels 14 . The rear wheel brake 16 applies a braking force (braking force) to the rear wheel 14 .

[0031] The front wheel brake 15 has: a front wheel brake di...

Abstract

The invention provides a front and rear linkage braking device for a vehicle, comprising: a pedal (41) for occupants to step on; an equalizer connected with the pedal (41) to distribute the braking operation force of the pedal (41) to the rear wheels a brake (16) and a front wheel brake (15), the rear wheel brake (16) having: brake shoes (45, 46) which apply a braking force to a brake drum (43) which rotates with the wheel (16); A support pin (47), which supports one end of the brake shoes (45, 46) in a freely rotatable manner; a camshaft (65), which has a cam (60) for opening the other end of the brake shoes (45, 46) , the cam (60) has chamfered parts (73, 74) on the side surface on the opposite side of the cam (60), so that even if the camshaft (34) is rotated to the other side, the brake shoes (45, 46) can be reduced. open volume.

Description

technical field [0001] The invention relates to an improvement of a vehicle front and rear linkage braking device. Background technique [0002] In a front-rear interlocking brake device for a vehicle, it is known that a drum brake is used as a rear wheel brake (for example, refer to Patent Document 1). [0003] As shown in Patent Document 1, the front and rear linkage braking device for vehicles has: a front wheel brake operating part, which makes the front wheel brake work; a rear wheel brake operating part, which makes the rear wheel brake and the front wheel brake work in linkage; A switch, which is at the end of the rear wheel brake operating member, distributes the operating force to the rear wheel brakes and the front wheel brakes. A linkage cable and a rear wheel brake cable are connected on the equalizer. The end of the interlocking cable is connected with the auxiliary operation part capable of engaging with the front wheel brake operation part. In addition, the...
