摘要： A clutch assembly for a motor vehicle drivetrain for coupling coupling elements for conjoint rotation includes a clutch unit, a brake unit and at least one permanent magnet between the clutch unit and the brake unit. The clutch unit is shiftable into a coupling state in which the coupling elements are coupled to one another by shifting the clutch unit from a first position in which the coupling elements are decoupled into a second position in which the coupling elements are coupled. First and second electrically energizable coils are electrically energizable to move the permanent magnet from the first position into the second position or vice versa. A holding plate is located adjacent to the at least one permanent magnet to suppress magnetic flux from the at least one permanent magnet to the brake unit. A motor vehicle drivetrain containing at least one clutch assembly is also provided.

摘要： A motor vehicle includes at least two drive motors, an automatic gearbox, and an electronic control unit, which, during a gear ratio adjustment between an engagement and a loading of a shift element, causes the shift element to be loaded with a predefined torque gradient at a first point in time at which at least one tooth-to-tooth position exists, up to a second point in time, cause the predefined torque to be limited to a maximum permissible torque during a predefined waiting period from the second point in time up to a third point in time, and cause the shift element to be further loaded with the previously predefined torque gradient after the waiting period or when the engaged state is detected.

The device includes an input shaft designed to receive the drive power provided by a first drive machine, an output shaft designed to output the drive power, and a first coupling device arranged between the input shaft and the output shaft. By way of the first coupling device, a torque can selectively be transmitted from the input shaft to the output shaft. The coupling device can be directly coupled to the output shaft. An additional coupling device is arranged between the input shaft and the output shaft, and can be directly coupled to the output shaft, such that a torque can selectively be transmitted from the input shaft to the output shaft. The additional coupling device is arranged parallel to the first coupling device with respect to the torque transmission.

摘要： A combined multistage hybrid transmission has a transmission housing; a transmission input shaft; a transmission output shaft; a first planetary gear set with a first sun pinion, a first ring gear, and a first carrier shaft on which at least one first planetary gear is rotatably mounted; a second planetary gear set with a second sun pinion, a second ring gear, and a second carrier shaft on which at least one second planetary gear is rotatably mounted. An electromechanical energy converter is rotationally fixed to the first sun pinion, wherein the first ring gear is rotationally fixed to the second sun pinion by an intermediate shaft. The transmission output shaft is arranged axially parallel and at a radial distance to the transmission input shaft. The drive power can be transmitted from the transmission input shaft by a first spur gear stage with a first transmission input spur gear and a first transmission output spur gear and by a second spur gear stage with a second transmission input spur gear and a second transmission output spur gear. The two transmission output spur gears are concentric to the transmission output shaft and the two transmission input spur gears are concentric to the transmission input shaft. The first transmission input spur gear is or can be rotationally fixed to the intermediate shaft, and the second transmission input spur gear is or can be rotationally fixed to the second ring gear.

摘要： A motor vehicle has at least two drive motors, at least one drive motor being an electric machine; a high-voltage accumulator; and an automatic gearbox, having at least one fixed transmission ratio and at least one power-split transmission ratio for transmission regulation starting from the at least one fixed transmission ratio. The motor vehicle further includes an electronic control unit, which is designed such that, when a gear change command is present, the shifting element to be opened of the fixed transmission ratio to be disengaged is unloaded in a torque-controlled manner by at least two of the drive motors. For the shifting element to be opened, the torque load is calculated and observed. The torque load is observed with the objective of bringing about a load change by way of a zero crossing in order to produce a no-load state at the shifting element. For producing the no-load state of the shifting element to be opened, a first drive motor and a second drive motor are controlled in a power split manner such that they, in terms of rotational speeds, maintain the transmission of the previously engaged fixed transmission ratio, and, in terms of torque, put the shifting element to be opened in an at least nearly no-load state, and a load change is brought about at the shifting element to be opened by a differential rotational speed, opposite the calculated torque load at the shifting element to be opened, being specified at the shifting element.

摘要： A hybrid planetary gear transmission includes first, second and third planetary gear sets with respective sun, ring and planetary gears, the three planetary gear sets being arranged at a distance from each other concentrically to a common transmission axis, a transmission input shaft for receiving drive power from at least one drive machine, and a transmission output shaft for outputting drive power to a drive train. The hybrid transmission further includes a first coupling system for selectively connecting the transmission input shaft to the sun gear of the first planetary gear set, a second coupling device for selectively connecting the transmission input shaft to the planetary gear carrier of the first planetary gear set, and a connection between the ring gear of the third planetary gear set to the planetary carrier of the second planetary gear set. A sun gear of additional planetary gear set is rotationally mounted with respect to the transmission housing, and a planetary gear carrier of the additional planetary gear set may be connected to a first drive machine and a ring gear of the additional planetary gear set may be connected to a second drive machine, such that drive power can be transferred from the planetary gear carrier of the additional planetary gear set to the transmission input shaft.
