Vibration damping apparatus

摘要

Apparatus for damping vibrations between the engine and the variable-speed transmission of a motor vehicle has two coaxial flywheels and a damper in a ring-shaped compartment of one of the flywheels. The damper has an annulus of coil springs in the compartment and a flange which is coupled to the other flywheel and has radial arms alternating with the coil springs. The coil springs store energy when the flywheels turn relative to each other because the one flywheel has axially extending recesses in the form of blind bores or holes for loosely inserted disc-shaped stops which engage the end convolutions of the coil springs in the neutral positions of the flywheels.
