摘要:
A hydrodynamic coupling device, especially a hydrodynamic torque converter, includes a housing which is rotatable about an axis of rotation, a turbine wheel mounted for rotation with respect to said housing, and a bridging clutch for transmitting torque between the housing and the turbine. The bridging clutch includes a first friction element which is essentially fixed against rotation with respect to the housing, and at least one second friction element which is essentially fixed against rotation with respect to the turbine, the friction elements having respective friction surfaces which can be brought into contact with each other. A first channel, provided in one of the friction surfaces, has first channel sections with radially closed inner ends and second channel sections with radially closed outer ends. A circumferentially extending second channel, provided in the other friction surface, establishes a fluid conducting connection between the first channel sections and the second channel sections when the first friction surface contacts the second friction surface. For every part of the friction surface which is opposite the second channel in a first relative rotational position, a second relative rotational position is provided in which this same part is in contact with the friction surface having the second channel.

A hydrodynamic clutch arrangement, particularly a torque converter or fluid coupling, includes a housing arrangement, a turbine wheel provided in the housing arrangement, and a lockup clutch arrangement by which a torque transmitting connection can be produced selectively between the turbine wheel and the housing arrangement. The lockup clutch arrangement includes at least two friction members which are rotatable with one of the housing arrangement and turbine wheel, and at least one counter-friction member which is interposed between the two friction members and is rotatable with the other of the housing arrangement and turbine wheel. A first friction facing on at least one of the friction members at its first side faces the at least one counter-friction member. This at least one of the friction members can be brought into frictional interaction, via a second friction facing, with another counter-friction member on its second side located opposite to the first side. The first friction facing has a larger friction surface area than the second friction facing.

A torsional vibration damper arrangement has a damper element arrangement which, at least in some areas, is arranged radially inside the fluid circulation zone and overlaps axially with the fluid circulation zone. The blade carrier is shaped in such a way that it conforms at least partially to an outer contour of the damper element arrangement.

A fluid clutch includes a housing having an interior that can be filled with fluid, an output element that can be rotated relative to the housing, a first friction surface arrangement coupled to the housing, a second friction surface arrangement coupled to the output element, and means for bringing the first and second friction surface arrangements into frictional engagement.

A rotational vibration damper includes a primary side (32) and a secondary side (46) which is rotatable with respect to the primary side (32) around an axis of rotation (A) against the action of a damper element arrangement (28). At least one damper element unit (42) of the first group (70) and at least one damper element unit (42′) of the second group (70′) are pre-loaded, and the primary side (32) and the secondary side (46) are pre-loaded in a basic relative rotation position with respect to one another. Proceeding from the basic relative rotation position of the primary side (32) with respect to the secondary side (46), a pre-loading path (V, V′) of at least one pre-loaded damper element unit (42) is shorter than a maximum relative rotation path of the primary side (32) with respect to the secondary side (46).
