Damping torsion vibrations in drive train - using lightweight sheet metal plates and axially compact setting of flywheel and screw spring

摘要

The damping device has two flywheel elements of which one is fixed on the engine crankshaft and the second has a friction face for a clutch disc of a separable friction clutch. The second flywheel element (7) lies in the direction of the axis of rotation (11) underneath the torsion damping spring (13) and has radially outwardly aligned support arms (18), for biasing the damping spring. This second flywheel element is pref. a ring disc wherein the supporting arms are spread out round the outer circumferential face (7b). These supporting arms (18) can be shaped from a sheet metal casing (14) placed round the ring disc. USE/ADVANTAGE - Compact lightweight design, with low mfr. costs.
