A torsional damper arrangement for a motor vehicle with a housing. The housing encloses a wet space. A momentum start clutch arrangement is arranged in the housing.

A clutch that has a synchronizer for matching a rotational velocity of a drive input with a rotational velocity of a driven output prior to engagement of a locking mechanism.

A shifting device for a motor vehicle is described, comprising a first coupling component which is adapted to be selectively rotationally coupled to a second coupling component with a form-fit. In an open state, the first coupling component is rotationally decoupled from the second coupling component. In a frictional fit state, the coupling components are rotationally coupled with a frictional fit via a first frictional fit ring and a second frictional fit ring. In a form-fit state, an actuating ring is rotationally coupled to the first coupling component and the second coupling component with a form-fit such that the latter are connected with a form-fit. A motor vehicle transmission, in particular a fully automatic stepped transmission having such a shifting device is additionally presented.

An engine assembly may include an internal combustion engine and an expander couplable to the internal combustion engine in a force transmitting manner. The engine assembly may also include a pulley mounted rotatably on a shaft of the expander. The pulley may be coupled to the internal combustion engine in a force-transmitting manner via a belt drive. The engine assembly may further include a first driver plate connected non-rotatably to the pulley and a second driver plate arranged adjacent thereto and connected non-rotatably to the shaft. The engine assembly may additionally include a clutch device including at least one actuating device and a coupling wheel. The coupling wheel may contact the first driver plate and the second driver plate when the clutch device is closed such that the pulley is connected with the shaft of the expander in a driving manner.

A clutch device for a clutch system has an input member that rotates at a first speed. A friction drive system is disposed between the input member and an output member. The clutch device is selectively movable by a fluid actuator assembly, between an engaged position in which the friction drive system drives the output member to rotate at the first speed, and a disengaged position in which a viscous drive system rotates the output member at a second speed slower than the first speed. A variable viscous fluid supply assembly includes a viscous fluid storage chamber, a valve, and a valve actuator that selectively drives the valve to move between an open position and a closed position to control an amount of viscous fluid available to the viscous drive system, thereby varying the second speed.
