A hybrid drive module for a motor vehicle having a housing, an electric machine with a rotatable rotor and a stator fixed with respect to rotation relative to the housing, and a clutch. A first half of the clutch is connected to a hub, and a second half of the clutch is connected to the rotor. The rotor is rotatably mounted at the hub via a first rolling element bearing. The hub is rotatably mounted via a second rolling element bearing at a bearing shield connected to the housing. A supporting of axial forces on both sides is carried out between the rotor and hub via the first rolling element bearing and between the hub and bearing shield via the second rolling element bearing. Also disclosed is a motor vehicle powertrain with a hybrid drive module.

A rotor carrier for a rotor of an electric machine and to a hybrid module with such a rotor carrier. The rotor carrier includes a tubular base body having elements on an outer circumferential surface facing the rotor for connection between base body and rotor, the base body is connected to a hub by a connection element. The connection element has an axial portion which extends along a part of the axial length of the base body and runs coaxial to the latter, in that receptacles for parts of a clutch are provided on an inner circumferential surface of the axial portion remote of the base body, and in that the connection element has a flange area adjoining the axial portion.

A cooling oil guiding device for rotating component parts. An annular oil channel extends in radial direction and cooling oil can be supplied from radially inward. The oil channel is partially open radially outwardly. A sealing area is provided in a radially outer area of the oil channel having blocking elements and outlet elements. The blocking elements are arranged radially inwardly of the outlet elements and have at least two passages in radial direction which are distributed along the circumference. Outlet channels aligned with the passages and inlets which are disposed between the outlet channels in circumferential direction are formed by the outlet elements. An annular channel is provided between the blocking elements and the outlet elements to connect the inlets with the outlet channels and passages, respectively.

A rotor carrier for a rotor of an electric machine and to a hybrid module with such a rotor carrier. The rotor carrier includes a pot-shaped base body. The base body overlaps only a portion of the axial extension of the rotor, in that the rotor carrier comprises a second supporting body that has elements on an outer circumferential surface for a positive engagement connection and/or frictional engagement connection between supporting body and rotor, in that the supporting body has a radially extending flange, and in that the bottom of the base body and the flange of the supporting body are connected to one another.

A cooling oil guiding device for a clutch actuatable by an axially movable piston. The piston is radially inward of the clutch, and separates a pressure space and a compensation space. The compensation space is delimited by an axially stationary compensation space cover and a seal cover coupled to the piston. The compensation space cover and the seal cover axially overlap radially outwardly and are axially movable relative to one another via a sealing element. An overflow opening connects the compensation space to an oil channel in the seal cover between the seal cover and the piston, the oil channel opens radially outward. A control edge is provided at a component part axially immovable relative to the piston, by which an oil flow exiting from the oil channel is guided through the clutch when the clutch is closed and is guided past the clutch when the clutch is open.

A multi-clutch arrangement between a drive unit and a transmission having at least three multi-plate clutches. The multi-plate clutches include an outer plate carrier in each instance such that the outer plate carriers form the housing of a multi-clutch arrangement.

A rotor carrier for a rotor of an electric machine and to a hybrid module. The rotor carrier includes a tubular base body and receptacles for parts of a clutch are provided on an inner circumferential surface remote of the rotor. The base body is connected to a hub by a connection element arranged adjacent to the receptacles. The connection element is formed by a radially extending annular flange, and in that the radially extending annular flange is arranged in axial direction between the receptacles and one end of the base body, or is characterized in that the base body is formed integral with a converter housing, and in that the connection element is formed by a radially extending housing wall or a housing cover of the converter housing.

A drive train unit (HY, G) for a motor vehicle includes a first shaft (TW), a second shaft (PW), and a third shaft (AN). The first shaft (TW) is rotatably mounted at an inner diameter of the second shaft (PW) with a first bearing (L). The second shaft (PW) is rotatably mounted at an inner diameter of the third shaft (AN) with a second bearing (L, L). A lube oil feed to the first bearing (L) and the second bearing (L, L) takes place through a bore hole (B) arranged in the first shaft (TW). An oil baffle chamber (S) is formed at an inner surface of the second shaft (PW) and includes a first outflow (S) and a second outflow (S). A drive train for a motor vehicle may include such a drive train unit (HY, G).

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.

Multiple-clutch assembly, dual-clutch transmission assembly and motor vehicle

A clutch arrangement is formed with drive-side and, output-side clutch elements and a clutch piston for operative connection and disengagement between the drive-side and output-side clutch elements. Associated with at least two clutch elements is an elastically deformable clutch element working mechanism through which the corresponding clutch elements can be acted upon in direction away from one another by an axial force to assist disengagement of the drive-side and output-side clutch elements. The clutch element working mechanism provides a considerable change in the gradient of the axial force exerted on the clutch elements as a result of even a small change of shape of the clutch element working mechanism so that a sharply rising axial force of the clutch element working mechanism works against the clutch piston.

A method for transmission of and damping of a mean torque with a superposed alternating torque in a torque transmission arrangement for a powertrain of a motor vehicle having an input and an output.
