Problems solved by technology

However, if the alternating torque generated during operation is smaller than estimated, the spring-mass system tends to stick to the mass to be damped and thus loses its necessary effect
On the other hand, when higher alternating torques are generated during operation than estimated, the initial critical frequency is damped better, but the amplitudes before and after the initial critical frequency are thus increased, so that the same May increase the risk of disturbing vibrations

Embodiment Construction

[0027] figure 1 A clutch plate 1 is shown which is accommodated in a non-illustrated friction clutch, which is arranged around an axis of rotation 2 and is connected with a hub 3 in a rotationally locking manner to the input shaft of the transmission. The disk part 4 is fixedly connected to the hub 3 , for example caulked as shown here, and accommodates a friction layer (not shown) for forming a friction engagement with the friction clutch.

[0028] Also arranged on the hub 3 is a rotational vibration damper 5 comprising a spring cage 6 formed by a cage part 7, a first energy accumulator 8 in the form of a coil spring 9 housed in the spring cage, a damping mass 10 and friction device 11. The torsional vibration damper 5 is rotatably accommodated on the hub 3 and is clamped axially on the disc part 4 with a cover plate 13 connected to the hub 3 , for example caulked as shown here, forming a slip clutch 12 between. To build up the prestressing force one cage part 7 bears aga...

Abstract

The invention relates to a friction clutch having a clutch disk (1, 1a) for transmitting torques by means of a friction apparatus (11, 11a). The friction apparatus is provided with a friction torque that depends on the relative angle of twist between a damping mass (10, 10a) and a mass to be damped so that damping of the rotational vibrations superposed on the torque to be transmitted can be designed at least substantially independently of the vibration amplitude of said rotational vibrations.

Description

technical field [0001] The invention relates to a friction clutch with a clutch disk for transmitting torque, with a friction device. Background technique [0002] Friction clutches with such a clutch disk have long been known and are used, for example, as isolating or starting clutches in motor vehicles between an internal combustion engine and a transmission. Here, the power transmission between an internal combustion engine, such as a diesel engine or a fast combustion engine, and a transmission, such as a manual transmission, an automatic manual transmission, a dual clutch transmission, is provided with a force-locking friction clutch from complete isolation through sliding isolation to complete isolation. Mode of action The force transmission is effected continuously by means of an actuation system in a controlled manner. In particular, in slipping states, an alternating torque can be superimposed on the average friction torque, which can lead to disturbing vibrations ...
