Abstract
A variable damper includes a first plate connected to a first rotating shaft and a second plate connected to a second rotating shaft. A damper spring transmits power between the first and second plates, and a variable friction apparatus regulates a frictional force between the first and second plates. The variable friction apparatus includes a solenoid coil, a solenoid pawl, a pressure plate with a slanted surface, a friction plate between the pressure plate and the second plate, a wedge contacting the pressure plate and movable along the slanted surface in response to the state of the solenoid pawl, and a wedge spring supporting the wedge.
Claims6
A variable damper transmitting power between a first rotating shaft and a second rotating shaft, comprising,
- a first plate connected to the first rotating shaft to rotate together with the first rotating shaft;
- a second plate connected to the second rotating shaft to rotate together with the second rotating shaft as an integral body;
- a damper spring transmitting power between the first and second plates by being pressed by relative rotation between the first and second plates;
- and
- a friction regulating means for variably regulating a frictional force between the first plate and the second plate.
