Abstract
The action of a primary damping device between two coaxial parts of a flywheel which is driven by the crankshaft of the engine in a motor vehicle and transmits torque to the input shaft of the change-speed transmission is influenced by a blocking device, by a friction generating device or by an auxiliary damping device in such a way that the resistance which the primary damping device offers to rotation of the two parts relative to each other decreases with increasing RPM of the engine. The blocking device, the friction generating device and the auxiliary damping device can be operated by centrifugal force in such a way that the two parts of the flywheel are positively or frictionally coupled to each other when the RPM of the engine is at or below the idling RPM.
Claims26
An assembly for taking up and compensating for torque-induced shocks, especially for taking up and compensating for fluctuations of torque which is transmitted by an internal combustion engine to a change-speed transmission in a motor vehicle, comprising a flywheel including coaxial first and second parts mounted for rotation at a variable speed and for limited angular movement relative to each other, one of said parts being arranged to receive torque from the engine and the other of said parts being arranged to transmit torque to the input element of the transmission;
- damping means operative to resist said relative angular movement;
- and means for regulating the resistance to rotation of said parts relative to each other so that such resistance decreases with increasing rotational speed of said parts.
