A clutch arrangement has a clutch device with a clutch housing capable of rotating around an axis of rotation, where the clutch device is designed to establish or to separate a working connection between a drive and a take-off and is provided with clutch components in the form of a piston and clutch elements. The piston produces a seal between a pressure space and a cooling space holding the clutch elements. The pressure space or the cooling space is connected to a supply unit so that it can be supplied with fluid medium, by connecting at least one supply line of the clutch device is connected to an infeed line of a gearbox and possibly by connecting at least one discharge line of the clutch device is connected to an outfeed line of the gearbox. An actuating line for a first supply line is assigned to the clutch device. The first supply line is independent of the infeed line for a second supply line or of the outfeed line for a discharge line.

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. The radial plain bearing, to bring it as close as possible to the crankshaft, is engaged in the vicinity of the end of the hub of the output-side inertial mass, which end faces the crankshaft.

A friction clutch, in particular for motor vehicles, with a clutch housing which can be detachably connected to a centrifugal mass of an internal combustion engine, and a clutch disc, pressure plate and clutch mainspring located inside the clutch housing whereby the centrifugal mass and the clutch housing come into contact in the axial direction. A spring supplies the retaining force between the centrifugal mass and the clutch housing. The spring which applies the retaining force is advantageously a plate spring. As a result of this configuration, the clutch housing can easily be assembled to the centrifugal mass by snapping it on.

A torsional vibration damper has an drive-side transmission element with at least one planet carrier rotatable relative thereto. The planet carrier is provided with at least one planetary gear, which is engaged with a sun gear on the one hand and with an internal gear on the other. In addition, there is an output-side transmission element, and one of the transmission elements has a control mechanism for a spring device arranged between the transmission element and at least one planetary gear train element. The planetary gear train element can be driven for a movement that depends on the speed and rotational direction of the two transmission elements relative to one another. At least two of the planetary gear train elements are designed, within a predeterminable roll-off range, with a generating cam eccentric to the associated bearing of the planetary gear train element, through which it is possible to change the distance of the interengagement of the two planetary gear train elements from their bearings for the purpose of adjusting the transmission of the planetary gear train in dependence on the deflection amplitude of the two transmission elements relative to one another.

This invention relates to a clutch disc for a friction clutch in which the connection between the hub and the friction linings is made by several leaf-spring-like elements distributed over the circumference, which elements are fastened in their central area to the hub, are essentially tangential to the axis of rotation and run at some radial distance from the axis of rotation in both directions, and are connected by means of their terminal areas to the friction linings.

A torsional vibration damper is designed with a driving-side transmission element, with at least one planet carrier which can rotate relative to the transmission element and which planet carrier is provided with at least one plane wheel which is engaged on one hand with a sun gear and on the other hand with a ring gear, and with a driven-side transmission element.

A torsional vibration damper for a bridging clutch of a hydrodynamic clutch arrangement has a drive-side damping device, which can be brought into working connection with the housing of the clutch arrangement and is provided with a drive-side transmission element, which acts via a drive-side energy-storage group on an intermediate transmission element, and a takeoff-side damping device, which uses a takeoff-side group of energy-storage devices to establish a working connection between the intermediate transmission element and a takeoff-side transmission element, which is connected to a takeoff-side component of the hydrodynamic clutch arrangement. A predetermined stiffness ratio is obtained between the energy-storage devices of a first group and the energy-storage devices of a second group, and the energy-storage devices of the drive-side group have a stiffness different from that of the assigned energy-storage devices of the takeoff-side group.
摘要:
A clutch device has a housing connected to a drive; a takeoff, which is mounted with freedom of rotation in the circumferential direction relative to the housing; and at least one friction clutch, which is mounted in the housing and which can be shifted between an engaged position and a released position. The clutch has clutch components including at least one pressure-exerting device and at least one clutch element which can be actuated by the pressure-exerting device, both the clutch element and the pressure-exerting device being able to shift position to a limited extent in the axial direction. The clutch element has at least one friction surface and a clutch hub in working connection with the takeoff. Beginning at a point of contact between the engaged position and the released position and continuing until the engaged position is reached, the torque of the drive can be transmitted via the housing and the friction clutch to the takeoff, whereas on the other side of the contact point and continuing until the released position, this torque transmission is suspended. A torque-building arrangement, which exerts force on the pressure-exerting device in the direction pointing away from the clutch element of the friction clutch, is assigned to the pressure-exerting device. This torque-building arrangement uses the pressure-exerting device as a first support element on one side and the clutch element as a second support element on the other side. On at least one of these support elements and/or on the torque-building arrangement, at least one flow passage is provided for the fluid which is present in a cooling space inside the housing in which the friction clutch is disposed.
