A constructional unit for a hybrid powertrain of a motor vehicle includes: an electric machine with a stator and a rotor, wherein the rotor is configured to transmit a torque to the powertrain; a clutch arrangement with at least one clutch actuation unit, wherein the clutch arrangement is configured to decouple an internal combustion engine from the powertrain, the internal combustion engine being provided parallel to the electric machine for transmitting a torque; and a vibration absorber apparatus configured to reduce vibrations in the powertrain. The clutch actuation unit is arranged axially substantially radially within the vibration absorber apparatus.

A hybrid drive module () which is constructed to transmit a torque from an input side () to an output side () includes a torsional vibration damper () which is coupled to the input side () and which works at least partially on the principle of power splitting, a disconnect clutch () which is coupled to the torsional vibration damper () and to the output side () and which is constructed to interrupt a torque flow from the input side () to the output side (), and an electric drive component () which is coupled to the output side () and which is arranged so as to introduce a torque component provided by the electric drive component () into the torque flow downstream of the disconnect clutch ().

Hybrid drive module and powertrain

A drive unit for a motor vehicle includes an electric machine which has a stator, a rotor and clutch for producing a rotary driving connection of the rotor to a drive element.

A hybrid drive arrangement for a vehicle with an internal combustion engine for driving, under engine power, and at least one electric machine (), for electric driving, and with a double-clutch transmission. The electric machine () can be separated from the internal combustion engine by at least one separator clutch (), in the form of a wet-operating, hydraulically actuated disk clutch. The outer disk carrier () of the separator clutch () and the outer disk carriers (A) of the two double clutches, of the double-clutch transmission, are connected and mounted on the transmission housing ().

Hybrid drive arrangement

A drive unit includes an internal combustion engine with a driven shaft, a transmission with an input shaft, and an electric machine arranged between the internal combustion engine and the transmission and comprising a stator and a rotor which can be coupled at least indirectly to the driven shaft of the internal combustion engine and to the transmission input shaft in order to transmit torque. The drive unit includes a clutch arranged in the torque transmission path between the internal combustion engine and the transmission. To facilitate the decoupling of rotational irregularities occurring in the drivetrain of the hybrid vehicle the drive unit has a first torsional damper and a second torsional damper, and at least the rotor of the electric machine is arranged within a torque transmission path formed between the torsional dampers.

An actuating device for applying actuating forces in a friction clutch device for engaging and disengaging a friction clutch assembly of the friction clutch device. The torque transmission device comprises the actuating device for transmission of torque between a drive unit and a transmission which also includes the friction clutch device. A method for installing a torque transmission device of this type. Various aspects relate to setting of a pre-load on a bearing of the actuating device, setting an over-dead-point configuration for a compensation spring associated with at least one rotary member of the actuating device, setting a rotation movement range for the rotary member and/or an axial movement range for an actuating element which can be displaced axially by rotation movement imparted to the rotary member, and producing either a normally engaged or disengaged characteristic in a normally-engaged or normally-disengaged friction clutch assembly with the compensation spring.

The torque transmission paths have different transmission characteristics and, based on their transmission characteristics, can be ordered in a sequence of torque transmission paths has a clutch arrangement by which at least one of the torque transmission paths can be activated. It is provided that the clutch arrangement has a clutch unit which is associated with a group of torque transmission paths and by which a torque transmission path of a group of torque transmission paths can be selectively activated. A plurality of groups of torque transmission paths are provided, each group having only one individual torque transmission path, or a plurality of groups of torque transmission paths are provided, at least one group having a plurality of torque transmission paths, or a plurality of groups of torque transmission paths are provided, at least one group having an individual torque transmission path and at least one additional group having a plurality of torque transmission paths. At least one group of torque transmission paths, insofar as it includes a plurality of torque transmission paths, has only torque transmission paths which do not immediately follow one another in sequence.

Automatic transmission

An actuating device for automatic operation of a gear change in a transmission that produces a change in predetermined translation ratios of the gear change transmission in any desired sequence comprises first and second drives that are in active connection with a selector shaft. The first drive is connected to the selector shaft via a guide mechanism which comprises at least one constraint guide that corresponds to a shifting path. The second drive is in active connection with the selector shaft for providing an operating force in the axial direction and an operating force in the circumferential direction of the selector shaft. The resulting movement depends on the operating position of the guide mechanism.

An adjusting device for operating a friction clutch is brought into active connection with the friction clutch via an output device driven by a drive. The output device includes a compensation device that compensates for a wear-induced position change of the pressure spring of the friction clutch by permitting a length change of the output device. For this purpose, the compensation device includes a fixing device that secures the relative positions of the components of the output device to each other. The fixing device is releasable in a predetermined operating state of the adjusting device by a control element. When released, the fixing device allows the relative movement between the components of the output device required to implement the length change of the output device.
