摘要:
A hydrodynamic clutch arrangement includes a clutch housing in which at least one hydrodynamic circuit formed by at least one pump wheel and one turbine wheel is provided. A bridging clutch can be actuated to produce an engaging movement to establish a working connection between a drive and a takeoff and to produce a disengaging movement to release this working connection. The hydrodynamic circuit and at least one pressure space are each connected by a flow route to pressure medium reservoir for actuating the clutch. At least one flow route serving to the fill the clutch housing is provided with a device for reducing the flow volume, which opens during the operating state to unblock the flow route but closes during the non-operating state to delay, at least, the drop in the internal pressure inside the clutch housing and thus in its filling volume.

A hydrodynamic clutch arrangement includes a clutch housing which can rotate about an axis of rotation; a hydrodynamic circuit formed by a pump wheel and a turbine wheel in the clutch housing; and a bridging clutch which can be actuated to establish and release a working connection between a drive and a takeoff. First flow routes connect the hydrodynamic circuit and a pressure space to at least one pressure medium reservoir, wherein said first flow routes serve to fill the clutch housing with pressure medium for actuating the bridging clutch. A second flow route carries pressure medium out of the clutch housing during an operating state, and a flow reducer in the second flow route closes to at least impede flow out of clutch housing in a non-operating state.

A hydrodynamic torque converter includes a housing with an interior space and a pump wheel; a turbine wheel installed in the interior space and rotatable about an axis with respect to the housing; and a bridging clutch including a first friction surface formation connected essentially nonrotatably to the converter housing, and a second friction surface formation connected essentially nonrotatably to the turbine wheel. A piston element divides the interior space into a first space containing the turbine wheel and a second space facing away from the first space, wherein a pressure increase in the second space brings the first and second friction formations into frictional engagement to connect the housing to the turbine wheel for rotation in common. Fluid flow openings in the piston element connect the second space to the first space in the radial area of the friction surface formations.

摘要:
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 fluid circulation arrangement in the housing causes fluid to circulate around the friction surfaces without requiring a simultaneous exchange of fluid to and from the interior.
摘要:
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 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).
