摘要: A master cylinder for use in a hydraulically actuated clutch or brake system of a motor vehicle, includes a casing formed with a bore, and a piston unit axially displaceable within the bore. The piston unit includes a piston-shaft sleeve received in the bore and having one end formed with a bottom to define an interior, at least two retainer shells received in the interior of the sleeve free of play, and a piston rod having a spherical head swingably mounted to the retainer shells and provided to respond to a manual actuation of a pedal. The retainer shells are each formed at a pedal-proximate end of the piston-shaft sleeve with a spherical recess to define a ball socket in which the spherical head snaps in and is received in form-fitting manner.

摘要: A master cylinder for a hydraulic friction clutch, said master cylinder being connected to a physically actuatable pedal by a piston rod (17) which is articulated in semi-shells (14) enclosed in a piston skirt bushing (10), an end of said piston skirt bushing (10) remote from the piston rod (17) being connected to a piston (7) which is longitudinally displaceable in a guide sleeve (96) of the master cylinder (1), an end face of said piston (7) delimiting a pressure chamber (8) wherein the semi-shells (14) fill an inner space of the piston skirt bushing (10) without play and comprise a cup-shaped recess (15) in which a ball head (16) of the piston rod (17) is retained by positive locking, the piston skirt bushing (10) forming a structural unit with the radially stepped piston (7).
