Abstract: A shoe mounts an outer spring defining a longitudinal direction and an inner spring arranged within the outer spring. The outer and inner springs define corresponding end sides of the outer and inner springs, and the shoe defines an end side of the shoe. A spring-position limitation limits the outer spring in its longitudinal direction and enables the inner spring to emerge at the end side of the shoe out of the outer spring. A driver primary element exerts a pressure on the inner spring as the driver approaches the outer and inner springs in a direction of the corresponding end sides of the outer and inner springs.

Abstract: A damper mechanism having preferable torsion characteristics that exhibit different characteristics on positive and negative sides by way of a simplified structure is provided. In the damper mechanism, a hub 6 is rotatable with respect to plates 12 and 13. Coil springs 33 are compressed on positive and negative sides of torsion characteristics. Elastic members 36 are arranged to operate in a rotating direction in parallel with the coil springs 33. The elastic members 36 are compressed on the positive side of the torsion characteristics, but are not compressed on the negative side of the torsion characteristics until a torsion angle exceeds a predetermined value. The elastic members 36 generate a frictional resistance when being compressed in the rotating direction, but no other friction generating mechanism is employed.

Abstract: A clutch disk has a hub area with a rotational axis, the hub area carrying a friction lining assembly radially outside of the hub area. A damper mass assembly can move circumferentially around the rotational axis relative to the hub area and the friction lining assembly against the action of an elastic support assembly.

Abstract: A torsional vibration damper comprising an input member for connection with a vehicle engine and an output member for connection with a vehicle transmission, the members being mounted for limited relative rotation about a common axis against a damping means comprising one or more circumferentially acting compression springs. Each spring acts between a first abutment formed as an integral part of the input member and a second abutment formed as an integral part of the output member. The damper may also include one or more elastomeric springs or blocks which are subjected to compression in end zones of the relative rotation of the input and output members. Other inventive features of the damper include support members for avoiding fouling of the elastomeric springs or blocks by the compression springs and the use of cantilevered pivot pins for the connection of bob-weight connecting linkages connected between the input and output members.

Abstract: A torsional vibration damper, which may be in the form of a twin mass flywheel, and which has an input member (11) designed to rotate generally in a first plane (A1), an output member (12) designed to rotate generally in a second plane (A2), relative rotation of the input and output members being possible against the action of a link-type damper (40). The damper is arranged to allow the first and second planes in which the input and output members rotate to tilt relative to each other during use of the damper to relieve internal stresses. This ability to tilt may be provided by self-aligning main bearings (50) or by the use of self-aligning pivot bearings (65) in the link-type damper.

Abstract: A damper disk assembly is provided for use in a clutch device. The damper disk assembly has a pair of plates 5 and 6 (rotary member) elastically coupled to the hub flange 8 (rotary member) by a damper mechanism 4. The damper mechanism 4 is designed to reduce disadvantages due to nonparallel compression of an elastic member in the damper disk assembly. The damper mechanism 4 includes a plurality of coil spring assemblies 13. The coil spring assemblies 13 have a large coil spring 30, a small coil spring 31 and a pair of spring seats 34. The paired spring seats 34 are arranged on the circumferentially opposite ends of the small coil spring 31. The spring seats 34 support the circumferentially opposite ends of the small coil spring 31, and are engaged with the inner side of the small coil spring 31. The spring seats 34 are supported for rotation with respect to two kinds of rotary members around a shaft parallel to a rotation axis of the rotary members.

In one embodiment, the rubber element 12 is positioned between both the seat elements 11 and is capable of expanding and contracting. The rubber element includes a projection 20 and a through-hole 16 is provided in each of the seat elements 11.

Abstract: A clutch friction element having elongate elastic elements (24) interposed circumferentially between two guide washers (18) and a shell (20). Recesses (27), which the shell (20) has for the elongate elements (24), are open radially. The guide washers (18) are connected to each other by an arch (45) and, on the internal surface of this arch, a lining (46) of synthetic material is applied radially.

Abstract: A flywheel apparatus including a first centrifugal mass connected to a drive mechanism and a second centrifugal mass connected to the first centrifugal mass by a torsional vibration damper, whereby the second centrifugal mass is rotatable with respect to the first centrifugal mass and located on the second centrifugal mass is a clutch housing. The clutch housing can have an application plate which is non-rotational but can move axially. The clutch housing can also have an application element which applies an application force, and a clutch plate which is located between the application plate and a counterpressure plate, whereby the clutch housing together with the counterpressure plate forms a pre-fabricated unit which can be fastened to the corresponding centrifugal mass by fastening elements.

Abstract: A clutch having a primary part and a secondary part for coupling together two coaxial rotating shafts including a driven shaft. The second part includes a driving disk, a trailing disk and tangential spring bodies forming a non-positive, engaging relationship between the driving disk and the trailing disk. At least one tangential spring body is a clamping body which is disposed within the second recess and abuts the radial edges of the first recess. The clamping body includes a cylinder, a piston slidably disposed within the cylinder to form a closed cylinder space. A cylindrical body made of an elastic material is disposed within the cylinder space. The cylindrical body completely occupies the cylinder space under initial axial compression of the piston whereby the cylindrical body absorbs further axial forces as an incompressible medium.
