The invention relates to a brake master cylinder assembly of a novel fluid infusion structure, and belongs to brake master cylinders in the technical field of automobile brake systems. Comprising a main cylinder body, a liquid inlet hole, a first piston component, a second piston component, a main leather cup and an auxiliary leather cup, a liquid supplementing channel is additionally arranged in the liquid inlet hole of the main cylinder body, and the auxiliary leather cup has the functions of pressure building and liquid supplementing. The auxiliary packing cup has the advantages that the structure is novel, the liquid supplementing channel is additionally arranged in the liquid inlet hole of the existing brake master cylinder, the function of the auxiliary packing cup is adjusted from the pressure building and isolating function to the pressure building and liquid supplementing function, the liquid supplementing mode of the existing plunger type master cylinder is changed, the liquid supplementing performance of the brake master cylinder is greatly improved, the liquid supplementing channel uses the liquid inlet hole of the existing brake master cylinder, the structure is simple, and the cost is low. And no new parts are input, so that the problem of liquid supplementation in the brake cavity when the brake liquid in the brake pipeline cannot flow back into the brake cavity in time is solved, and the generation of abnormal sound caused by water attack is also avoided.
本发明涉及一种新型补液结构的制动主缸总成,属于汽车制动系统技术领域的制动主缸。包括主缸体、进液孔、第一活塞部件、第二活塞部件、主皮碗、副皮碗,在主缸体的进液孔内新增补液通道,副皮碗的功能为建压和补液。优点是结构新颖,在现有制动主缸进液孔内增加补液通道,将副皮碗的功能由建压和隔离功能调整为建压和补液功能,改变现有柱塞式主缸的补液方式,大大提升制动主缸的补液性能,补液通道借助现有制动主缸的进液孔,结构简单,无新零部件投入,解决了制动管路内的制动液不能及时回流到制动腔内时,制动腔内的补液问题,还避免水击异响的产生。
