Abstract
A vibration damping apparatus which is installed in the power train between the crankshaft of an internal combustion engine and the input shaft of a change-speed transmission in a motor vehicle has two coaxial flywheels which are rotatable relative to each other against the opposition of one or more dampers. The damper or dampers are installed in a fluid-containing chamber which is provided in part in one of the flywheels.
Claims39
A torsional vibration damping apparatus, particularly for use in motor vehicles, comprising a first flywheel connectable to the output element of the engine in a motor vehicle and a second flywheel coaxial with and rotatable relative to the first flywheel and connectable to the input element of the change-speed transmission of a motor vehicle, particularly by way of a friction clutch;
- antifriction bearing means interposed between said flywheels;
- a chamber containing a supply of viscous fluid medium;
- and at least one damper operating between said flywheels, disposed in said chamber and comprising at least one energy storing element, a first component rotatable with said first flywheel and having a first window for said at least one energy storing element, and a second component rotatable with said second flywheel and having a second window for said at least one energy storing element.
