Torsion damper with dynamic vibration damper - includes mass connected by elastic block to support connected to hub

摘要

The torsion damper contains two coaxial parts (A,B) movable relative to each other against resilient means (1,13) and damping means (2,40) within the limits of a certain angular range. A dynamic vibration damper (30) coupled to the hub has a mass (33) which is connected by at least one elastic element (32) to a support (31) which, possibly after compensation of play, is connected rotationally movable to the hub. The inherent frequency of the said dynamic vibration damper conforms with the resonance frequency of the torsion damper fitted on the output shaft. ADVANTAGE - The mass of the dynamic vibration damper can be adapted so that no retaining means are required.
