The invention provides a piston assembly and a master cylinder for a brake system, the piston assembly comprises a cylindrical piston body and a magnet assembly, the magnet assembly is fixedly installed on the circumferential side portion of the piston body in a detachable mode, a concave portion extending in the longitudinal direction (X) is formed on the circumferential side portion of the piston body, and the concave portion is provided with a magnet. A through hole which extends in the radial direction of the piston body, penetrates through the piston body and is communicated with the concave part is formed in the piston body, the magnet assembly comprises a magnet, a shell wrapping the outer side of the magnet and a buckle device formed on one main surface, in the thickness direction (Z), of the magnet assembly, and the buckle device extends away from the magnet and is integrated with the shell. The magnet assembly is received in the recess such that the snap means extends through the through bore in the piston body and forms a snap connection with the piston body at a distal end of the snap means remote from the housing.
本发明提供了一种活塞组件以及用于制动系统的主缸,该活塞组件包括柱状的活塞本体和磁体组件,磁体组件以可拆卸的方式固定地安装在活塞本体的周向侧部上,活塞本体的周向侧部上形成有沿纵向方向(X)延伸的凹部,活塞本体内形成有沿活塞本体的径向方向延伸贯穿活塞本体且与凹部连通的通孔,磁体组件包括磁体、包覆在磁体外侧的壳体、以及在磁体组件的沿厚度方向(Z)的一个主表面上形成的卡扣装置,卡扣装置背离磁体延伸且与壳体成一体,磁体组件容置在凹部中,使得卡扣装置延伸穿过活塞本体内的通孔并且在卡扣装置的远离壳体的远端端部处与活塞本体形成卡扣连接。
