Master cylinder device for hydraulic system of motor vehicle, has piston movable to and fro in master cylinder, and joint socket provided at piston rod that is hinged at piston using socket, where joint head is provided at piston

摘要

The device has a piston (5) movable to and fro in a master cylinder. A piston rod (8) is hinged at the piston using a joint socket (12), which is divided into disks (15) in a circumferential direction, where the disks encompass a spherical joint head (10). The joint socket is provided at the piston rod, and the joint head is provided at the piston. The disks are encompassed by a circular element (20), which radially limits outward movement of the disks. The disks are radially and outwardly deformed with reduced force when the circular element is present in a mounting position.
