TORSIONAL OSCILLATION DAMPER Russian patent published in 2004 - IPC

FIELD: torsional oscillation dampers; automobile clutches.

SUBSTANCE: proposed torsional oscillation damper includes at least one pre-damper acting in preset range of angles which is provided with lesser rigidity energy accumulator and at least one main damper acting in preset range of angles which is provided with larger rigidity accumulator. Energy accumulators work between respective inlet and outlet parts of pre-damper and main damper. Outlet part of torsional oscillation damper is made in form of bush provided with inner profile for fitting on gearbox shaft and flange with inner profile which forms outlet part of main damper. Inner profile is thrown into engagement with outer profile of bush; this profile is used for allowing the flange of main damper to perform limited turns relative to bush. Oscillation damper includes also at least one disk part which forms inlet part of main damper on which friction linings are located, at least one friction unit and spring acting on part of friction unit; this spring is coupled with outer profile of bush.

EFFECT: extended amplitude of oscillations being damped; minimum amount of parts; facilitated assembly.
