Apparatus for damping torsional vibrations

摘要

Apparatus for damping torsional vibrations in the power train of a motor vehicle has two coaxial flywheels one of which is driven by the engine and the other of which can transmit torque to the input shaft of a transmission by way of a friction clutch. The flywheels are rotatable relative to each other against the resistance of a damper. Certain features of the apparatus reside in the dimensioning and distribution of its parts in the radial and axial directions of the flywheels to reduce the dimensions of the apparatus. The torque transmitting connection between at least one pair of neighboring rotary parts of the apparatus employs a slip clutch which yields when the applied torque exceeds a certain value. An intermittently or continuously active hysteresis device is utilized to operate in parallel with the energy storing springs of the damper.
