A hybrid module is provided for the drivetrain of a motor vehicle, which drivetrain has an electric machine, an internal combustion engine and a transmission. The hybrid module has (i) a first unit with a rotor element and a separating clutch which is arranged within the rotor element, (ii) a second unit with a clutch device comprising at least one clutch, and (iii) a third unit with a housing part. The first unit and the second unit are connected to each other to form a preassembled overall unit, and said overall unit is installed projecting into the third unit and is connected here to the third unit. A hybrid module constructed in such a manner can be produced by means of particularly simple assembly and is very compact. A method for assembly of said hybrid module is also provided.

A counterbalance for balancing a part that is able to rotate about an axis of rotation is disclosed, in particular a part of a torque transmission device, such as a friction clutch unit. The counterbalance has a longitudinal axis and a shaft section that includes a knurled portion with ridges that are inclined in relation to the longitudinal axis. Also disclosed is a torque transmission device, in particular for a drive train in a motor vehicle, including an axis of rotation and at least one part that is able to rotate about the axis of rotation. In this torque transmission device, at least one counterbalance of said type is arranged on the part for balancing purposes.

A hybrid module has an intermediate element via which a counter plate, or at least one of the counter plates, of a coupling device is fixedly connected to a rotor element. At least one pressure plate and/or intermediate plate of the coupling device is here connected rotationally fixedly but axially displaceably to the rotor element via the at least one intermediate element. The result is a compact plate connection which is advantageous in particular for multiplate clutches. The intermediate element may be arranged radially outside the plates (pressure plate(s), counter plate(s) and any intermediate plates) of the coupling device.

A clamping device for a shaft-hub connection in a torque-transferring device in a drive train of a vehicle. The connection is an axial spline connection between an externally toothed shaft and an internally toothed hub. An externally toothed ring is provided for clamping the shaft and hub, wherein the externally toothed ring includes an annular body having external teeth. Fastening tongues of leaf-spring-type design are provided on and extend from the radially inner side of the annular body. Outer ends of the leaf-spring-type fastening tongues are attached to the shaft, and the teeth of the toothed ring mesh with teeth of the hub. By rotating the toothed ring against a force provided by the fastening tongues, a clamping force is produced on the shaft-hub connection in the assembled state and is introduced into the shaft-hub connection through the teeth and fastening tongues.

A double clutch assembly has a diaphragm spring aligned and maintained to prevent uneven wear of a disc. A diaphragm spring is deformable in an axis direction with respect to a cover casing which receives a driving force from an engine. A center plate is connected to the cover casing and an auxiliary cover casing is coupled to the center plate to form a support point. The pressure plate is selectively connected to a center plate disc when the diaphragm spring contracts. An auxiliary pressure plate is coupled to the center plate. A disc installed between the center plate and the pressure plate provides the driving force transmitted through the pressure plate to the transmission. An auxiliary disc installed between the center plate and the auxiliary pressure plate provides the driving force through the auxiliary pressure plate to the transmission.

The invention relates to a duplex clutch for coupling a drive shaft of a motor vehicle engine to a first transmission input shaft and/or a second transmission input shaft of a motor vehicle transmission, including a first partial clutch for coupling the drive shaft to the first transmission input shaft. A second partial clutch couples the drive shaft to the second transmission input shaft. A first actuating cup displaces a first compression plate of the first partial clutch and a second actuating cup displaces a second compression plate of the second partial clutch.

A dual-clutch for a motor vehicle includes an input, first and second outputs, friction plates for producing a drive connection between the input and the first and second outputs alternately, a housing including an inlet and an outlet, containing at least a portion of the friction plates, and a cooling system including a fan impeller rotating with the input and producing an air stream flowing through the housing from the inlet to the outlet.

A clutch mechanism for motor vehicles, having a dry individual clutch or a dual clutch, transmits torque from an engine to the transmission or selectively to one of two transmission sections. The clutch has a central disk and, on at least one side, a pressure plate. In order to further improve the cooling effect, especially in the region of the central disk and of the pressure plates, the central disk and/or at least one of the pressure plates is composed of two partial plates, wherein the mutually facing inner surfaces of the partial plates are provided with intermeshing vanes such that the intermeshing vanes of the two partial plates form an interior space having through channels which brings about flow in a radial direction or in a direction having a radial component.

A clutch device includes a first and a second input side as well as a first and a second output side. The input sides and the output sides can be rotated about a common axis of rotation. The clutch device furthermore includes a first clutch between the first input side and the first output side and a second clutch between the first input side and the second output side. A third clutch may be provided between the first input side and the second input side. A first hydraulic actuating device is associated with the first clutch, a second hydraulic actuating device is associated with the second clutch, and a third hydraulic actuating device is associated with the third clutch. A radial flange, which receives an axial actuating force of one of the actuating devices, includes a radially extending feed for hydraulic fluid to one of the actuating devices.
