Apparatus for transmission of torque in the power train of a motor vehicle has coaxial rotary first and second torque transmitting devices, each of which can constitute a simple or a composite flywheel, and a torsional vibration damper operating between the two devices. The damper is installed in an annular chamber which is sealed at its periphery and is flanked by two sidewalls of the first torque transmitting device. The damper includes a washer-like partition which is affixed to the second torque transmitting device and has arms extending radially outwardly into the chamber. The radially inner part of the annular chamber is sealed by annular seals having annular carriers borne by the sidewalls at opposite sides of the partition, and deformable annular lips secured to the carriers and bearing upon the respective sides of the partition. The carriers and the lips consist of different materials and the seals serve to prevent penetration of impurities into and/or the escape of lubricant from the chamber. Such lubricant is in contact with coil springs which form part of the damper and oppose rotation of the torque transmitting devices relative to each other.

Apparatus for damping torsional vibrations

A torsional vibration damper for use in a motor vehicle power train has an input disc part connected to the vehicle engine and an output disc part to the downstream side of the power train. The disc parts are rotatable relative to each other against the action of an energy accumulator such as a coiled compression spring. The energy accumulator is seated in a suspension device that is divided into two socket parts. The socket parts are rotatable in relation to each other as well as in relation to the input and output disc parts. The input and output disc parts have biasing means engaging the socket parts so that, for a first sense of relative rotation between the input and output disc parts, the biasing means of the input disc part engage the first socket part and the biasing means of the output disc part engage the second socket part while, for a second, opposite sense of relative rotation, the biasing means of the input disc part engage the second socket part and the biasing means of the output disc part engage the first socket part, with the result that for either sense of relative rotation between the input and output disc parts, the energy accumulator is always force-biased in a compressive sense between the socket parts.
