Abstract

A hydraulic clutch has an impeller wheel, a turbine wheel with a turbine wheel shell, and a torsional vibration damper. The turbine wheel is drivable by the impeller wheel. The turbine wheel shell is mounted in an axial and radial sliding bearing so as to be rotatable with respect to a turbine wheel hub. The torsional vibration damper is arranged on the turbine wheel hub so as to be fixed with respect to rotation relative to it. The turbine wheel hub is drivable by the turbine wheel via the turbine wheel shell and the torsional vibration damper. The turbine wheel shell acts on the torsional vibration damper via a connection element. The axial sliding bearing is spatially offset with respect to the radial sliding bearing.

Dependent claims

A hydraulic clutch comprising

an impeller wheel which can be driven to rotate about an axis of rotation,
a turbine wheel hub on said axis,
a turbine wheel which can be driven to rotate with respect to said hub by said impeller wheel, said turbine wheel comprising a turbine wheel shell,
a sliding bearing support between said turbine wheel and said turbine wheel hub, said sliding bearing support comprising an axial sliding bearing and a radial sliding bearing, wherein said axial sliding bearing is spatially offset with respect to said radial sliding bearing,
a torsional vibration damper arranged on said turbine wheel hub and fixed against rotation with respect to said turbine wheel hub, and
a connection element by which said turbine shell acts on said torsional vibration damper to drive said turbine wheel hub.
