  • Patent number: 6227977
    Abstract: A torque can be transmitted by a bushing 101 located between a pair of torque transmitting members. The bushing 101 is constructed out of resin and metal such that the part made of resin does not significantly contact the torque transmitting members. The bushing 101 includes an annular portion 102 made of resin and a connecting portion 103 made of metal. The connecting portion 103 is molded in an annular portion 102. The connecting portion 103 has parts (117 and 118), which are connected with the torque transmitting members so as to be able to transmit a torque therebetween. In a preferred embodiment, the bushing 101 is part of a dampening mechanism 6, which generates a friction between a hub flange 18 and a hub 3 when both of the portions rotate relatively. The bushing 101 supports a plurality of springs 21 to elastically couple a fixing plate 20 of the hub flange 18 to the hub 3. The bushing 101 rotates with the hub 3, while the fixing plate 20 rotates with the hub flange 18.

  • Patent number: 6089983
    Abstract: A torsion damping device couples together an input element, such as a clutch friction wheel, and an output element comprising a hub. The damping device comprises a main damper and a predamper. The main damper comprises two guide rings arranged axially on either side of a damper plate. Each of the two dampers includes an axially acting friction device, and the damper plate meshes, with a circumferential clearance, with the periphery of a hub ring formed on the outer periphery of the hub. Both of the friction devices are incorporated in a single component, which comprises a first friction ring surrounding a second friction ring, and which includes radial arms which join the two friction rings together in such a way that the friction rings rotate together but are displaceable axially with respect to each other due to axial deformability of the radial arms.

  • Patent number: 5878856
    Abstract: A flywheel device has at least two inertial masses which can rotate relative to one another against the action of elastic elements of a damping device, one of which inertial masses, namely the output-side inertial mass which is farther from a drive system, such as for example the crankshaft of an internal combustion engine, is guided both radially and axially by way of a bearing arrangement with respect to the input-side inertial mass. The bearing arrangement has at least one axial plain bearing and one radial plain bearing. Both plain bearings guide the output-side inertial mass with respect to the input-side inertial mass with a clearance, the size of which is determined so that when a wobbling motion is introduced from the crankshaft to the input-side inertial mass, the output-side inertial mass, under the effect of centrifugal forces, can perform a self-stabilization.

  • Patent number: 5829567
    Abstract: A clutch disc includes an elastic mounting to absorb both wobbling movement and to compensate for axially offsetting transmission components. Between the hub and the components which can rotate with respect to the hub, there is a spring element which makes it possible by means of two different types of fingers to accomplish both a radially elastic centering and an axially elastic clamping. The clutch disc can thereby absorb both wobbling movements and axial offsets.
