[0009] In recent years, from the viewpoint of product attractiveness, there is also a desire to adopt the disc brake disclosed in Patent Document 2 compared with the drum brake disclosed in Patent Document 1 in motorcycles, but there is a 3-piston caliper The cost of disc brakes is relatively high, and it is desired to develop an interlocking brake system, which is an inexpensive structure that does not use expensive 3-piston calipers, and uses two components, the front wheel brake operating part and the interlocking brake operating part. A system capable of independently braking the front wheels

Abstract

In a two-wheeled motor vehicle equipped with a front wheel brake operating member for braking the front wheel and an interlocking brake operating member for interlocking braking of the front wheel and the rear wheel, according to the front wheel braking The disc brake (30) is operated by the operation of the operating member and the drum brake (31) is operated by the operation of the interlocking brake operating member. The disc brake (30) is arranged on one side in the vehicle width direction and is placed on one side. The drum brake (31) is mounted on the front wheel (WF) so as to be disposed on the other side in the vehicle width direction, and the brake drum (60) of the drum brake (31) is disposed so as to be open to the other side in the vehicle width direction. . This allows the disc brake to be used to brake the front wheel and at the same time, it is possible to configure the interlocking braking system at low cost.

Description

technical field [0001] The present invention relates to a motorcycle comprising a front wheel brake operating element for braking a front wheel and an interlocking brake operating element for interlocking braking of a front wheel and a rear wheel. Background technique [0002] In Patent Document 1 and Patent Document 2, there is known a two-wheeled motor vehicle which brakes the front wheels according to the operation of the front wheel brake operating member, and brakes the front wheels according to the operation of the interlocking brake operating member. and rear wheels for linkage braking. In the technique disclosed in Patent Document 1, a pair of cables respectively connected to the front wheel brake operating member and the interlocking brake operating member are connected in parallel to the brake arm of a single drum brake mounted on the front wheel. , in the technology disclosed in Patent Document 2, a disc brake equipped with a 3-piston caliper (pot caliper) having...
