The invention relates to a second piston part of a brake master cylinder assembly, and belongs to parts of plunger type brake master cylinders in the technical field of automobile brake systems. The second piston member is composed of a second piston and a second piston spring, one end of the second piston spring is in interference fit with a boss of the second piston for axial limiting, and the other end of the second piston spring is used for being in clearance fit with a boss in the bottom of a master cylinder body. The second piston member has the advantages that the structure is novel, compared with a conventional second piston member, the second piston member disclosed by the invention has the advantages that a spring limiting base and a small gasket in the second piston member are omitted, the processes of point riveting and size inspection are reduced, and higher low-cost property and higher efficiency are achieved; and the modular standard design can be applied to various types of plunger type brake master cylinders, the brake performance is not affected, the assembly links are reduced, the assembly efficiency is improved, the cost is reduced, and the cost performance is good.

    本发明涉及一种制动主缸总成的第二活塞部件,属于汽车制动系统技术领域中柱塞式制动主缸的部件。由第二活塞和第二活塞簧组成,其中第二活塞簧一端与第二活塞的凸台过盈配合、进行轴向限位,第二活塞簧的另一端用于与主缸体底内凸台进行间隙配合。优点是结构新颖,与常规的第二活塞部件相比,减少了第二活塞部件中的弹簧限位座和小垫圈,减少了点铆及尺寸检验的流程,具有更高的低成本性和更快的效率性;模块化标准设计,可应用于各种类型柱塞式制动主缸,不影响制动性能,减少了装配环节,提高了装配效率,从而降低了成本,具有良好的性价比。
