A friction clutch for a drivetrain of a motor vehicle includes and input part, an output part, a spring device, a pressure pot, and a connecting means connecting the pressure pot to the inner-plate carrier. The input part includes an outer-plate carrier which is rotatable about an axis of rotation by a drive motor, and an outer plate rotationally fastened to the outer-plate carrier. The input part includes a rotor carrier, an inner-plate carrier separate from the rotor carrier, and an inner plate rotationally fastened to the inner-plate carrier. The spring device is for bracing the outer plate and the inner plate together with a pressing force to close the friction clutch. The connecting means includes an actuating surface via which the friction clutch can be actuated by an actuating device.

An improved clutch hub assembly is disclosed. The improved clutch hub assembly provides improved wear resistance at the interfaces between separator plates and a clutch hub while allowing an operator to have improved clutch lever control and modulation when manually engaging or disengaging the clutch system.

A clutch arrangement arranged between a drive unit and a transmission, with at least one multi-plate clutch having an outer plate carrier and an actuation element. The actuation element, particularly a piston, has openings for receiving the outer plate carrier.

A differential including a case (5), a side gear (100,200), a first lock plate (1000) having a first side and a toothed side, and a second lock plate (2000) having a first side facing the case and a toothed second side facing the toothed side of the first lock plate (1000). The differential further includes a cam plate (300) between the side gear (100,200) and the first lock plate (1000) and a clutch pack (40) between the cam plate (300) and the first lock plate (1000). The cam plate (300) includes a splined neck (330) extending towards the first lock plate (1000), and the clutch pack (40) includes at least one active clutch disc (20) internally splined to the splined neck (330).

A vehicle drive apparatus includes: a first bearing disposed between a rotor support member and a case in a radial direction so as to restrict movement of the rotor support member to a first axial side relative to the case; and a second bearing disposed between a connecting shaft and the case in an axial direction so as to restrict movement of the connecting shaft to a second axial side relative to the case. A fluid transmission device is disposed on the first axial side relative to the connecting shaft. The rotor support member includes a tubular portion having a tubular shape extending in the axial direction and fitted to an outer peripheral surface of the connecting shaft. Movement of the connecting shaft to the first axial side relative to the tubular portion is restricted.

A clutch includes a hub and a flange located radially inside and outside, respectively, with respect to the clutch rotational axis and associated with hub and flange sides of the clutch. A spring elastically supports the hub and flange sides against each other in the circumferential direction in a torque-transmitting manner. A bearing radially supports the hub and flange sides against one another for rotation around the axis and includes an outer ring supporting the hub and an inner ring supported on a bearing pin associated with the flange side. A friction device connects the hub and flange sides in a friction-locked and torque-transmitting manner in the circumferential direction and includes a friction element and a friction surface which are pretensioned against one another in the axial direction. A tensioning device includes a tensioning element that applies force to, and axially pretensions, the friction device and bearing.

A clutch pack for a clutch in a drive train of a motor vehicle includes an axis defining an axial direction and a disk, rotatable about the axis, for contacting a counter-disk to transfer a torque. The disk includes a main body with a contact region for absorbing torque from or transferring a torque to the counter-disk, a toothed region for torque-transmitting contact with a disk carrier, and a region of specific elastic softness in the axial direction disposed between the contact region and the toothed region. In an example embodiment, the region of specific elastic softness in the axial direction is a steel sheet spring region.

An inner disc carrier (LT) for a wet-type friction clutch (K0) may have a driving toothing including ridges (S, SX) and grooves (N) for the form-locking accommodation of discs (L) of the friction clutch (K0). Each of a first group of the ridges (S) has a first opening (A1) produced in a chip-less shaping process and a section (ST) extending radially inwardly at the first opening (A1) and created during production of the first opening (A1). Hydraulic fluid supplied radially from inside the inner disc carrier (LT) from a first axial position is guided through the first openings (A1) to the discs (L). Hydraulic fluid supplied radially from inside the inner disk carrier (LT) from a second axial position is guided past the discs (L). The sections (ST) of the ridges (S) act as a damming contour for hydraulic fluid supplied radially from the second axial position.
