Title: Aiding master cylinder and braking control device
Inventor: ISONO HIROSHI
IPC: B60T8/48
Filed: 2000-02-17
Abstract: PROBLEM TO BE SOLVED: To provide an aiding master cylinder superior in operation feeling and a braking control device. SOLUTION: A push rod 40 for a booster 20 is passed through an end wall 64 partitioning an aiding chamber 102 from a low pressure chamber 34 in a liquid-tight and slidable manner, protruded to the aiding chamber 102 and put in contact with the bottom face of a recessed portion 120 of a first pressure piston 90 in a separatable manner. A master cylinder pressure is generated by the supply of a liquid pressure to the aiding chamber 102 for traction control without footing a brake pedal 18. During the control, an aiding pressure is operated on the push rod 40 to allow the brake pedal 18 to be footed with a less feeling of blank operation. When the liquid pressure is supplied to the aiding chamber 102 in emergent braking, the liquid pressure is supplied at a time, whereby the first pressure piston 90 is suddenly moved to produce a decrease in footing force. However, an emergent braking aiding pressure is greater than an aiding pressure given from the first pressure piston 90 for the push rod 40 during separation and reaction is increased after separation to change the footing force decreased to be increased, which gives a driver a less unusual feeling.
