Abstract

A clutch assembly may have an axially slidable first plate, an axially fixed second plate disposed opposite the first plate, and a clutch pack arranged between the first plate and the second plate. The clutch pack may have a number of axially slidable consecutively arranged friction plates and separator plates. The assembly may also have an actuator axially movable between a first position and a second position, where, in the first position, the clutch pack is opened and, in the second position, the clutch pack is closed and the friction plates are frictionally engaged. The assembly may also have a return spring configured to bias the actuator in a direction away from the clutch pack towards the first position. The assembly may also have an engagement spring element configured to exert an elastic force on the clutch pack.
