Abstract
The invention relates to improvements in dampers which can be utilized in the power trains of motor vehicles to absorb torsional vibrations of the rotary output shaft of the engine and/or torsional vibrations of the rotary input element of a change-speed transmission normally receiving torque by way of a torque converter. One of the dampers is installed externally of the housing of the torque converter and, if used, another damper can be installed in the power flow between the piston of a lockup clutch in the housing of the torque converter and a turbine of the torque converter. The external damper can include an energy storing component and a friction generating component which latter is or can be sealed from the energy storing component.
