Abstract
A composite flywheel wherein a primary mass is rotatable by the engine of a motor vehicle and can transmit torque to a secondary mass--which serves to rotate the clutch plate of a friction clutch--by way of several sets of coil springs and a planetary transmission. A friction clutch serves to oppose certain angular movements of the primary and secondary masses relative to each other, and a slip clutch is provided to limit the magnitude of the torque which can be transmitted by the planetary transmission.
Claims78
A torsional vibration damping apparatus comprising first and second masses rotatable with and relative to each other about a common axis;
- means for transmitting torque between said masses, including energy storing means acting in a circumferential direction of said masses, and a planetary;
- and means for limiting the magnitude of the torque which is transmittable between said masses by said torque transmitting means.
A torsional vibration damping apparatus comprising a rotary torque transmitting first component;
- a torque receiving second component rotatable with and relative to said first component about a common axis;
- means for transmitting torque between said components comprising (a) energy storing means and (b) a planetary including at least one carrier rotatable about said axis relative to said first component, at least one pinion rotatably mounted on said at least one carrier, an internal gear coaxial with said at least one carrier and meshing with said at least one pinion, and a sun gear meshing with said at least one pinion, one of said components being provided with means for stressing said energy storing means in response to rotation of said components relative to each other and said first and second components respectively having first and second masses rotatable at a plurality of speeds and relative to each other in clockwise and counterclockwise directions, said energy storing means being installed in at least one of said components to react against at least one of said masses and to bear against at least one intermediate mass forming part of said planetary and being rotatable about said axis at a velocity dependent upon said speed and upon the direction of rotation of at least one of said first and second masses relative to the other of said first and second masses;
- and means for limiting the magnitude of torque which is transmittable by said torque transmitting means from one of said first and second masses to the other of said first and second masses.
