Abstract: In a spindle system with a hollow spindle for a linear actuator, the linear actuator has a telescopic tube system including an outer tube and at least one inner tube arranged coaxially with the outer tube and at least partially surrounded by the outer tube. A bearing is arranged to transmit axial forces between the hollow spindle and the outer tube. The hollow spindle at least partially surrounds an inner shaft of the spindle system and is connected to the inner shaft of the spindle system by one or more tappets of a positive and axially displaceable shaft-hub connection. The hollow spindle has a bearing seat for the bearing and an external thread on an outer side.

Abstract: A connector assembly for connecting a linear actuator to a telescopic housing includes an adapter part and a connector part. The linear actuator includes a telescopic tube system having an outer tube surrounding an inner spindle system. The telescopic housing has first, second, and third telescopic members arranged coaxially, with the third telescopic member arranged at least partially inside the first telescopic member and at least partially outside the second telescopic member. The adapter part is provided for attachment to the third telescopic part. The connector part is provided for attachment to the outer tube. The adapter part and the connector part have mechanical formations for producing a positive connection in the axial direction, which is arranged for connecting the outer tube to the third telescopic part.

Abstract: A friction clutch for a motor vehicle for frictional coupling a first shaft and a second shaft, comprising a plurality of clutch discs articulated interactively on a clutch basket and a clutch hub, wherein the first shaft is connected to the clutch basket and the second shaft is connected to the clutch hub and the clutch discs are selectively coupled by an associated actuation unit. Associated with the clutch basket is an oil-collection and guiding arrangement through which oil spun off the clutch basket is collected and delivered into a collection region outside the clutch basket. A switching device coupled to the actuation unit controls the backflow of the oil from the collection region outside the clutch basket (KK) in the direction of the clutch discs.

Abstract: A clutch unit for a motor vehicle comprises a friction clutch and an actuator for actuating the friction clutch, the actuator having a first ramp ring and a second ramp ring, of which at least one can be rotated relative to the other ramp ring, in order to exert an axial force on the friction clutch. Furthermore, the clutch unit comprises a metering device for feeding a cooling fluid in a metered manner to the friction clutch. The metering device has a first metering section which is assigned to the first ramp ring, and a second metering section which is assigned to the second ramp ring, the first metering section and the second metering section together delimiting a metering opening for the cooling fluid. The first metering section and the second metering section interact in such a way that the cross section of the metering opening, which cross section is delimited by the metering sections, can be varied by way of a relative rotation of the ramp rings.
