A starting element () for use, for example, in a drivetrain of a motor vehicle, includes a piston () which divides a first volume () that can be filled with a fluid from a second volume () that can be filled with a fluid, wherein the piston () comprises at least one fluid passage () which allows the fluid at least occasionally to pass through the piston () from the first volume () into the second volume () and/or from the second volume () into the first volume (). The at least one fluid passage () comprises a passage component part () and a receiving opening () in the piston (). The passage component part () is inserted into the receiving opening so that at least one passage opening () is formed which allows the fluid to pass through at least occasionally.

Starting element

A hydrodynamic coupling arrangement, particularly hydrodynamic torque converter, wherein at least one torsional vibration damper arrangement comprises at least two torsional vibration dampers which are arranged so as to be radially staggered and substantially aligned axially with respect to one another, wherein the first torsional vibration damper is arranged on the radially outer side of the second torsional vibration damper, and wherein the at least one torsional vibration damper arrangement is coupled with the other torsional vibration damper arrangement in an area radially between the first damper element unit and the second damper element unit.

Hydrodynamic coupling arrangement, particularly hydrodynamic torque converter

A torque transmission includes a housing arrangement drivable around an axis of rotation and filled with fluid and a clutch arrangement between the housing arrangement and a driven member. The clutch arrangement has a first friction surface formation rotatable with the housing arrangement and a second friction surface formation rotatable with the driven member. A clutch piston is movable axially for producing and canceling frictional engagement of the first and the second friction surface formation. A piston carrying element is connected to the clutch piston on the radially inner side for axial movement of the clutch piston. The piston carrying element has in its radially inner end region a first axial supporting area for axially supporting the driven member at the piston carrying element and a second axial supporting area for supporting the piston carrying element at the housing arrangement.
