Abstract
A hydrodynamic torque converter comprises a pump wheel, a turbine wheel, and a stator, which combine to form a hydrodynamic circuit. The stator is centered with respect to an axis of rotation and has a freewheel hub so that it can be mounted on a freewheel, which hub is carried by a radially outer freewheel component and is connected by means of a transmission element part to a radially inner freewheel component with freedom of relative rotation. At least one first freewheel component has a damping device, which serves to reduce the ability of this freewheel component to rotate relative to the other, second freewheel component and which for this purpose can be brought into working connection with the second freewheel component.
Claims23
A hydrodynamic torque converter comprising:
- a hydrodynamic circuit comprising a pump wheel, a turbine wheel, and a stator, the stator being centered around an axis of rotation and having a hub;
- a freewheel comprising:
- a first, radially outer freewheel component which carries the hub;
- a second, radially inner freewheel component;
- and
- a transmission element part, which connects the first freewheel component to the second freewheel component so that the first freewheel component can rotate with respect to the second freewheel component;
- and
- a damping device which damps rotation of the first freewheel component with respect to the second freewheel component when the damping device is in a working connection with the second freewheel component.
