Abstract

A gearshift mechanism for a motor vehicle with hydraulically actuated multiple clutch, particularly a twin clutch, has a first gear input shaft to drive a first group of gears and a second gear input shaft to drive a second group of gears. The two gear input shafts are each assigned a clutch unit being coaxial to one another. A stationary housing accommodates the two clutch units. At its end face, the housing can be closed off by a housing cover that has a central opening through which a drive hub of a clutch cage is guided. The housing cover is provided with a bearing flange around the central opening, on the outside of which the clutch cage is supported. This advantageously supports the clutch on the housing and makes it possible to achieve a support effect for a dual mass flywheel or the crankshaft end of the internal combustion engine.
