    摘要: A master cylinder for the clutch or brake of a motor vehicle has a housing for a reciprocable piston one end of which receives the spherical head of a reciprocable piston rod. The head is held in a desired position relative to the piston by a one-piece or composite coupling device having a first section exerting a pull or bearing upon the head of the piston rod and a second section which is confined in or surrounds the end of the piston and urges the first section in a direction to hold the piston rod against axial movements relative to the piston. The coupling device and/or the piston are or can be made of a plastic material, and the connection between such parts is or can be established by snap action.

    摘要: The cylinder of a cylinder and piston unit in the friction clutch engaging/disengaging apparatus of a power train for use in a motor vehicle is assembled of two separately produced coaxial tubular walls. The outer wall is made of a plastic material and is of one piece with an extension serving to supply pressurized hydraulic fluid from a pump or another source to the plenum chamber for the reciprocable annular piston between the two walls. The inner wall is made of sheet metal and one of its end portions is separably coupled to one end portion of the outer wall by snap action. Such one end portion of the outer wall is separably secured to a support, usually the transmission case in the power train of the motor vehicle.

    摘要: A roller bearing unit, in particular, a needle bearing unit, which has an outer ring, a roller body cage, roller bodies and several sealing rings. The roller bodies are housed in the roller body cage and are supported externally in the radial direction against the inner surface of the outer ring and are arranged to internally support a shaft aligned in the axial direction. The sealing rings are housed in the outer ring and designed to seal against a fluid flowing the axial direction. The sealing rings are arranged and/or designed such that the resultant sealing effect generated by the rings is direction dependent with relation to the fluids flowing in the axial direction.

    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).
