Abstract
Apparatus for damping vibrations between the output element of the engine and the power train in a motor vehicle has flywheels which are rotatable relative to each other. One flywheel is mounted on the output element of the engine and another flywheel is connectable to the power train by a friction clutch. vibration dampers are installed between the flywheels, and such dampers are confined in a housing which is provided on the one flywheel and contains a supply of viscous fluid medium for the parts of the dampers. The housing is the input member of the dampers and the output member of the dampers is a flange which extends into the housing and is axially movably coupled to the other flywheel.
Claims15
An apparatus for counteracting fluctuations of torque, comprising at least two flywheel elements which are rotatable relative to each other about a common axis, said elements including a first flywheel element connectable with a prime mover and a second flywheel element connectable with a transmission by way of a clutch;
- and damper means interposed between said flywheel elements, said damper means including at least two resilient dampers operating in parallel, one of said at least two dampers being arranged to oppose, alone, a first stage of rotation of said first and second flywheel elements from a starting position and the other of said at least two dampers being arranged to oppose, with said one damper, a next-following second stage of rotation of said first and second flywheel elements relative to each other, said damper means including wear resistant means between said first flywheel elements and said at least one resilient damper element.
