Title: Interlocking braking device
Inventor: TSUCHIDA TETSUO
IPC: B62L3/08
Filed: 1996-03-18
Abstract: PURPOSE: To provide an interlocking braking device which keeps good brakes operation feeling. CONSTITUTION: Fluid pressure produced in a front master cylinder 2 by brakes operation is transmitted to a braking device of one system (a front primary braking device 11) and, by such braking force, the braking device of the other two systems (a front secondary braking device 21 and a rear brake 31) are actuated. Therefore suitable feeling rigidity with respect to the brakes operation is secured by shortening an oil passage 3 for transmitting brakes operation force. Because oil pressure is directly transmitted from a secondary master cylinder to the front secondary braking device 21, the oil pressure is not transmitted to the front master cylinder 2. As a result, it is unnecessary for oil pressure fluctuation to be transmitted to a brake lever 1.
