摘要:
A hydrodynamic torque converter with a pump wheel, a turbine wheel, and a stator, which combine to form a hydrodynamic circuit, where the flow conditions in the hydrodynamic circuit can displace the turbine wheel axially toward the pump wheel when the converter is operating in pull mode and in the opposite direction when operating in push mode, where at least one axial bearing on the drive side of the freewheel and at least one drive-side thrust washer establish a working axial connection between the turbine wheel and a component of the freewheel. The drive-side thrust washer has a stationary element, by which the washer is in axial contact with a first freewheel component, and a pressure-exerting device, which is in working connection with this stationary element, is free to shift position in the axial direction relative to the stationary element, and, as a result of the action of a compensating element, remains in contact with both the drive-side axial bearing and a second freewheel component regardless of the axial position of the turbine wheel with respect to the pump wheel, whereas the stationary element arrives in axial contact with the drive-side axial bearing only after the turbine wheel has come to within a very short axial distance of the pump wheel.
