Torque transmission device for car, has elastic elements arranged in series through phasing body, where pendular masses of pendular damping unit are movably mounted on torque output element or on phasing body

摘要

The device has a torque input element including a flywheel (1) coupled to a crankshaft of a thermal engine, and a torque output element coupled to an input shaft of a gearbox, where groups of elastic elements (22, 23) act against rotation of one of the torque input and output elements relative to each other. The elastic elements are arranged in series through a phasing body (33) so that elastic elements of each group are deformed in phase with each other, where pendular masses (64) of a pendular damping unit (63) are movably mounted on the torque output element or on the phasing body.
