A starting element with a friction clutch and a piston configured to actuate the friction clutch. The starting element includes a piston space separated from a residual space of the starting element at least partially by the piston, a first connection constructed such that the piston is acted upon by a hydraulic medium proceeding from one side of the residual space, and a second connection fluidically connected to the piston space. A maximum pressure present at the second connection is equal to and/or less than a pressure present at the first connection.

Starting element, gearbox and drive train with the start element

A torsional vibration damper for damping a vibration component of a rotational movement around an axial direction has a damper mass to carry out an oscillation to damp the vibration component, a damper mass carrier to movably guide the damper mass, and a supporting body in contact with or can enter into contact with the damper mass in at least one operating situation of the torsional vibration damper. The supporting body is connected to the damper mass carrier to drive the supporting body relative to the damper mass carrier during rotation of the torsional vibration damper, and a support structure formed together with the supporting body to radially support the supporting body under a first operating condition and to radially release the supporting body under a second operating condition which differs from the first operating condition.

Torsional vibration damper

A tuned mass damper for damping a vibration component of a rotational movement around an axial direction includes a damper mass configured to perform an oscillation to damp the vibration component, a damper mass carrier to movably guide the damper mass, and a supporting body in contact with or to enter into contact with the damper mass in at least one operating state of the tuned mass damper. The supporting body has a catch structure d the damper mass carrier has a catch aperture via which the supporting body is connected to the damper mass carrier to secure the supporting body relative to the damper mass carrier in axial direction.

Tuned mass damper

A coupling arrangement is provided with a vibration reduction device and with a clutch device. The vibration reduction device has at least one torsional vibration damper, an input connected to a drive, and an output connected to the clutch device by which a connection between the vibration reduction device and a driven end is at least substantially produced in a first operating state, and this connection is at least substantially cancelled in a second operating state. The vibration reduction device has a mass damper system that cooperates with the torsional vibration damper and is connected to the output of the vibration reduction device.

Coupling arrangement having a vibration reduction device and having a coupler device

A wet clutch arrangement, particularly starting clutch for a vehicle, including a housing arrangement which is filled or fillable with fluid, a friction coupling region having a first friction surface formation rotating with the housing arrangement around an axis of rotation and a second friction surface formation that rotates with a driven element around the axis of rotation and which can be brought into frictional engagement with the first friction surface formation, a fluid coupling region with an impeller rotating with the housing arrangement around the axis of rotation and with a turbine that rotates with the driven element around the axis of rotation and which, along with the impeller, defines a toroidal fluid circulation space. The fluid coupling region is arranged radially outside the friction coupling region.
