Abstract
A torque converter which has a pump wheel, a turbine wheel, and a stator, which form a hydrodynamic circuit, and also a torsional vibration damper with a primary and a secondary damper element. The primary and the secondary damper element are connected to each other in a rotationally elastic manner by at least one set of springs. The turbine wheel has a turbine wheel shell and is supported rotatably with respect to a turbine wheel hub in a first bearing, which provides axial and radial support. The secondary damper element is mounted nonrotatably on the turbine wheel hub. The turbine wheel acts by way of an intermediate element on the primary damper element. The stator is mounted on a stator hub, which is supported by an axially operative second bearing on a turbine wheel base, which is connected to the turbine wheel shell. The first bearing is located radially outside the second bearing.
