DAMPING DEVICE FOR ABSORBING ROTATIONAL IMPULSES

摘要

A torsion damping assembly which is installed in a motor vehicle between the crankshaft of the internal combustion engine and the input shaft of the change-speed transmission has two coaxial flywheels one of which receives torque from the crankshaft and is rotatable, within limits, relative to the other flywheel which transmits torque to the input shaft of the transmission by way of a friction clutch. The flywheels are rotatable within limits relative to each other against the opposition of a damper and about the axis of a self-aligning or self-adjusting antifriction bearing one race of which is biased axially by a diaphragm spring reacting against the one or the other flywheel. The antifriction bearing surrounds a centrally located protuberance of the one flywheel and extends into a centrally located recess of the other flywheel. Such bearing can stand long periods of use because it holds the flywheels against wobbling and/or other stray movements relative to each other.
