Brake booster |
摘要 |
Reaction transmitting means of a brake booster includes a parallel combination of a first and a second reaction transmitting path each transmitting a brake reaction from a reaction disc to a valve plunger. The first reaction transmitting path includes a spring charged to a preset load, and the second reaction transmitting path includes a viscoelastic member as may be formed of rubber. With this construction, a hysteresis is obtained in both a low range of servo ratio during an initial phase of operation of a brake booster and a higher range of servo ratio during a later phase of operation, which occur before and after the spring in the reaction transmitting mechanism is compressed, thus allowing a good brake feeling to be maintained.
