The invention relates to the technical field of automobile brake devices, and discloses a vacuum booster of an automobile brake system which comprises a driving push rod, one end of the driving push rod is movably connected with a booster pump in a sleeved mode, first limiting grooves are formed in the left side and the right side of an inner cavity of the booster pump, and limiting plates are movably connected into the first limiting grooves in a clamped mode. According to the vacuum booster of the automobile brake system, the driving push rod can be driven to move when a brake pedal is stepped down, the acting force applied to the brake pedal can drive the limiting plates to continuously move along with continuous movement of the driving push rod, and at the moment, the limiting plates can continuously move relative to the limiting grooves and compress a limiting spring and a first reset spring; when the brake pedal does not apply pressure any more, the first reset spring and the limiting spring can provide reverse acting force to drive the limiting plates to automatically reset and prevent the limiting plates from inclining in the displacement process, and thus the advantage that the limiting plates can be prevented from inclining in the reset process is achieved.

    本发明涉及汽车制动装置技术领域,且公开了一种汽车制动系统真空助力器,包括主动推杆,所述主动推杆的一端活动套接有助力泵,所述助力泵内腔的左右两侧均开设有第一限位槽,所述第一限位槽的内部活动卡接有限位板。该汽车制动系统真空助力器,通过踩下制动踏板时会带动主动推杆的移动,随着主动推杆的继续移动,施加在制动踏板的作用力会带动限位板的继续移动,此时限位板即可相对限位槽继续移动,并压缩限位弹簧以及第一复位弹簧,当制动踏板不再施加压力时,第一复位弹簧以及限位弹簧会提供反向作用力带动限位板自动复位,并防止其位移中出现倾斜,从而实现了可防止限位板复位时出现倾斜的优点。
