Abstract

A hydraulically operated double clutch for a motor vehicle is used for the alternating coupling of a central shaft and a hollow shaft, which is concentric to this central shaft, of a speed change gear with the clutch housing driven by the engine output shaft. Thus a gear shifting becomes possible without an interruption of the traction force. The clutch housing is composed of a left cover plate and a lateral plate, of a right cover plate and a lateral plate as well as of a casing part connecting them. At the junction planes between the left cover plate and the lateral plate as well as the right cover plate and the lateral plate, annular pistons are fitted in, which can be acted upon by hydraulic pressure and, by means of cylindrical pins, resting against them on the end face, operate the two disk bundles.
