Abstract: A multiple clutch for a drivetrain of a motor vehicle includes an a axis of rotation, a first clutch, a second clutch, and an encoder part. The first clutch has a first clutch first component and a first clutch second component selectively rotationally connectable to the first clutch first component. The second clutch has a second clutch first component and a second clutch second component selectively rotationally connectable to the second clutch first component. The encoder part has a rotational speed or rotational position detection geometry, is arranged to be operatively connected to a sensor, and is used as a connecting element which rotationally conjointly connects the first clutch first component to the second clutch first component.

Abstract: A double clutch system for a drive train that includes a drive unit and a double clutch transmission. The double clutch system includes two wet-running, multi-plate clutches that include inner plate carrier components, each of which is non-rotatably connected to a respective transmission input shaft, and between which cooling oil is supplied to the multi-plate clutches. A pressure chamber is provided for the cooling oil radially inwardly of at least one of the multi-plate clutches and in an axial direction between the inner plate carrier components.

Abstract: A clutch unit (1) including at least one wet clutch (28, 29) and a torsional vibration damper (12) which are accommodated in a housing (8) driven by the drive unit. In order to simplify assembly, pre-assembled modular units (3, 4, 5) are formed that are joined together during the final assembly process. Advantageously, a separation point is provided between two modular units in the torsional vibration damper, wherein one modular unit (3) includes the energy accumulators (11) captively accommodated in a housing part (6), while the other modular unit (4) includes the output part of the torsional vibration damper as an input part (13) of the at least one wet clutch.

Abstract: A twin clutch assembly for a drive train including a twin clutch transmission, and a drive unit coupled to the twin clutch transmission through a wet running twin multi disk clutch. A drive side output hub is non-rotatably connected with a transmission input shaft that is rotatably disposed within a hollow transmission input shaft that includes a free end facing the drive unit and is non-rotatably connected to a transmission side output hub. A clutch cover is axially disposed between the twin clutch and the drive unit, and a drive element is axially supported and is non-rotatably connected to the drive unit. The transmission side output hub is axially supported toward the transmission by an axial support device at the free end of the hollow transmission input shaft.

Abstract: A clutch unit for use in the drive train of a motor vehicle between a drive unit and a transmission including at least one transmission input shaft. The clutch unit includes at least one wet clutch device that is provided with a plurality of clutch elements, in particular clutch discs, that are at least partially wetted by a coolant such as oil. The coolant carries away frictional heat that is generated by slippage between adjacent clutch discs during certain vehicle operating conditions. The heat absorbed by the clutch coolant is cooled by heat transfer from the coolant to a cooler that surrounds the clutch unit.

Abstract: The invention relates to a closure with a thermal safeguard function, comprising a closure body (1), which is used to seal a cavity (10) that is to be closed; a fusible safeguard element (2), which is inserted into the closure body and which keeps closed, at least indirectly, a through-opening (1.1), which is formed in the closure body. The inventive closure with a thermal safeguard function is characterized by the following features: the closure body comprises a bushing (3) provided with a continuous bore (3.1); the bushing is inserted into the through-opening of the closure body at an axial end (1.3) in such a way that the continuous bore and the region of the through-opening that is axially adjacent to the bushing are aligned flush with each other; the fusible safeguard element completely fills the continuous bore of the bushing over the entire cross section thereof along a given axial length.

Abstract: A twin clutch assembly in a drive train, which includes a twin clutch transmission and a drive unit, which can be coupled to the twin clutch transmission through a wet running twin multi disk clutch, with a drive side output hub, which is connected torque proof with a transmission input shaft, which is rotatably disposed within a transmission input shaft, which is configured as a hollow shaft, which includes a free end facing the drive unit, which is connected torque proof to a transmission side output hub, and which includes a clutch cover, which is disposed in axial direction between the twin clutch and the drive unit, and at which a drive element is supported in axial direction, which is connected torque proof to the drive unit. The transmission side output hub is supported in axial direction towards the transmission by means of a axial support device, which is configured spring elastic in axial direction, directly at the free end of the transmission input shaft, configured as a hollow shaft.

Abstract: A torque transmitting unit in the power train of a motor vehicle for transmitting torque between an engine crankshaft, and a transmission having at least one input shaft with at least one friction clutch. The transmission input shaft is coupled with the crankshaft by the friction clutch, which includes friction disks on the power input and/or output sides, and that are pressed together axially along an axis of rotation of the transmission input shaft to form a frictional engagement through a plurality of disks arranged in alternating layers in the axial direction. The disks are pressed against a stop by an actuator and with an actuating bearing interposed, wherein the actuator is connected to a fixed part of the transmission housing in a rotationally fixed connection. The friction clutch is a wet clutch.
