Abstract
Apparatus for damping vibrations between the crankshaft of the engine and the clutch plate of the friction clutch of a motor vehicle has a first flywheel which is driven by the crankshaft, a second flywheel which is rotatable relative to the first flywheel and can rotate the clutch plate, and a torque transmitting unit between the flywheels. The unit employs one or more dampers in an annular chamber of the first flywheel and a slip clutch on the other flywheel. The output element of the damper or dampers is a flange-like device which constitutes a diaphragm spring and transmits torque to an axially stressed resilent disc which forms part of the slip clutch. The disc is riveted to the second flywheel and is adjacent an axially stressed resilient diaphragm seal which engages the first flywheel to seal the chamber from the atmosphere.
Claims25
Apparatus for damping vibrations in a power train between an engine and a transmission in a vehicle, comprising at least two components which are rotatable relative to each other about on axis and include a first component connectable with the engine and a second component connectable with the transmission;
- and means for transmitting torque between said components, including at least one torsionally elastic damper and a slip clutch in series with said at least one damper, said slip clutch comprising a diaphragm spring device for transmission of torque between said damper and said slip clutch, means for stressing said device in the axial direction of said components including two radially offset abutments flanking said device and rotatable with one of said components, the other of said components having an annular chamber which is at least partially filled with a viscous fluid and includes a sealed radially outermost portion and a radially inner portion, said device having a radially outer portion and said torque transmitting means further comprising a diaphragm seal for the radially inner portion of said chamber and a torque transmitting disc, said disc and said seal being interposed between said one component and the radially outer portion of said device.
