More Information
Summary:A torsional vibration damper comprising an input member for connection with a vehicle engine and an output member for connection with a vehicle transmission, the members being mounted for limited relative rotation about a common axis against a damping means comprising one or more circumferentially acting compression springs. Each spring acts between a first abutment formed as an integral part of the input member and a second abutment formed as an integral part of the output member. The damper may also include one or more elastomeric springs or blocks which are subjected to compression in end zones of the relative rotation of the input and output members. Other inventive features of the damper include support members for avoiding fouling of the elastomeric springs or blocks by the compression springs and the use of cantilevered pivot pins for the connection of bob-weight connecting linkages connected between the input and output members. Various friction damping arrangements are also disclosed which can be speed and/or displacement dependent. A method of assembling the damper is also disclosed.
