The invention relates to the technical field of automobile brake pumps, and provides an automobile plunger brake pump which comprises a cylinder body, a first piston and a second piston which are arranged in a cavity in a sliding mode, leather rings are arranged on the first piston and the second piston and provided with sealing lip bodies, and the first piston and the second piston are provided with first guide channels. The first sliding part slides and then acts on the transmission part, so that the transmission part acts on the sealing lip body to support the sealing lip body towards the inner wall of the cavity, one end of the first spring acts on the first sliding part, the other end of the first spring acts on the inner wall of the first guide channel, and force for the pressure adjusting end to enter the first guide channel is provided. By means of the technical scheme, the technical problems that in the prior art, after a rubber sealing leather ring (4) of an automobile plunger brake pump is used for a long time, friction loss exists, the foot feels weak during braking for a long time, and certain potential safety hazards are caused are solved.
本发明涉及汽车刹车泵技术领域,提出了汽车柱塞刹车泵,包括缸体,第一活塞和第二活塞均滑动设置在腔体内,第一活塞和第二活塞上均设置有皮圈,皮圈具有密封唇体,第一活塞和第二活塞均具有第一导向通道,第一滑动件滑动后作用于传动件,使得传动件作用于密封唇体将密封唇体撑向腔体的内壁,第一弹簧一端作用于第一滑动件,另一端作用于第一导向通道的内壁,提供压力调节端进入第一导向通道的力。通过上述技术方案,解决了相关技术中汽车柱塞刹车泵的橡胶密封皮圈(4)在长时间使用后,会存在摩擦损耗的问题,长此以往使得刹车时脚感乏力,造成了一定的安全隐患的技术问题。
