Torque transmission device for drive train of e.g. bus, has mass element connected with primary or secondary part by flexible unit such that position of mass element is changeable during occurrence of torsional vibrations

摘要

The device has a coupling and a hydraulic damping part arranged between a primary part (8) and a secondary part (9), where the coupling is designed as a hydrodynamic coupling. A mass element is connected with the primary or secondary part by a flexible unit i.e. spring, such that position of the mass element is changeable during occurrence of torsional vibrations. The damping part is designed such that torsional vibrations are damped over a viscous medium flowing via a throttle gap, where position of the mass element is changeable in radial or circumferential direction of the device.
