The invention relates to the technical field of automobile braking, in particular to an automobile brake pedal assembly which comprises a control valve cylinder, an external air bag is arranged on the outer side of the control valve cylinder, the external air bag is filled with clean air, and a vent hole is formed between the control valve cylinder and the external air bag; two symmetrical impact rings are arranged in the control valve cylinder, the vent hole is located between the two impact rings, and a valve ring and a positioning ring are arranged in the control valve cylinder. According to the vacuum booster, through the externally-connected external air bag, when air needs to be input into the vacuum booster, clean air in the external air bag can supply enough air, the boosting action of the vacuum booster is completed, meanwhile, through the design of the sealing rubber sleeve on the push rod, the push rod can move in the moving process, and therefore the vacuum booster is not prone to falling off. And a sealing element with high sealing performance is not required to be added with the control valve cylinder, so that the resistance borne by the push rod during movement is reduced, dust is prevented from entering, the reaction speed of movement of the push rod is increased, and the force of a driver for stepping on the pedal is reduced.

    本申请涉及汽车制动技术领域,一种汽车制动踏板组件,包括控制阀筒,所述控制阀筒的外侧设有外置气囊,所述外置气囊内填充有洁净的空气,所述控制阀筒与外置气囊之间设有通气孔;所述控制阀筒内设有两个对称的撞击环,所述通气孔位于两个撞击环之间,所述控制阀筒内设有阀门环和定位环。本发明通过外接的外置气囊,使真空助力器中需要输入空气时,外置气囊中的洁净空气能供给足够的空气,完成真空助力器的助力动作,同时通过推杆上密封胶套的设计,使推杆在移动的过程中,不需要与控制阀筒进行高密封性的密封件的添加,从而减小了推杆移动时受到的阻力,避免了灰尘的进入,增大推杆移动的反应速度,减小驾驶员踩动踏板的力。
