ABSTRACT:
A lockout clutch on a torque converter includes an axially deflectable piston through which torque can be transmitted from the drive side of the torque converter to its output side. The lockout clutch also has a torsional vibration damper having an input part connected to the piston and an output part connected to the turbine wheel of the torque converter. One of the input part and the output part includes a cover element with control elements for energy storage devices acting on the torsional vibration damper on at least one radial support of the cover element. The control elements are designed to project into the cover element with a depth at which the associated energy storage devices rests on a control element along substantially the extension width in the contact area of the control element. The control elements are also designed to avoid penetration to the axial support at least at the point where the other of the input and output elements engages the energy storage elements. This engagement occurs with substantially axial projections, on which axial securing devices to retain the energy storage devices are provided. The axial projection are designed so that pressurization of the energy storage devices is ensured over their entire width in the axial extension direction of the axial projections.
