Abstract
The hydrodynamic torque converter (,) comprises a pump wheel (,) in a casing (,), a turbine wheel (,) and a turbine distributor (,). There is also a bypass coupling (,) including an axially moving piston, a torsional oscillations absorber (,) with input and output parts rotating relative to each other in opposition to force accumulators. Its turbine wheel comprises a hub (,) housed axially on the torque converter output hub (,). A connection with the rotational clearance, the splines (,), is provided between the two hubs. A fixed connection, by splines (,) is between the input part of the absorber and the turbine wheel hub. The two sets of splines are in the same axial position radially one in the other.
