  • Publication number: 20220176801
    Abstract: A drive system for a hybrid motor vehicle with a motor shaft rotationally coupled to the output shaft of an internal combustion engine, a first and second electric motors with respective first and second rotor shafts arranged in a radially offset manner to each other, a drive part rotationally connected to the second rotor shaft and which can be rotationally connected to at least one wheel, and a transmission unit operatively installed between the motor shaft, the two rotor shafts, and the drive part. A shift device controls the shift position of the transmission unit such that the shift device rotationally connects the motor shaft to the first rotor shaft while the second rotor shaft is decoupled in a first shift position, the shift device rotationally connects the motor shaft both to the first and second rotor shafts in a second shift position, and the shift device rotationally connects the two rotor shafts together while the motor shaft is decoupled in a third shift position.

  • Publication number: 20220176797
    Abstract: A shifting device for a hybrid drive system of a motor vehicle, with a centrally arranged shaft, a first gear wheel rotatably mounted relative to the shaft and a second gear wheel rotatably mounted relative to the shaft and offset along the shaft relative to the first gear wheel, a sliding sleeve slidably received directly in the first gear wheel and non-rotatably connected thereto, which sliding sleeve is configured such that, in a first displacement position, it connects the shaft in a rotationally fixed manner to the first gear wheel, while the second gear wheel is rotationally decoupled from the shaft, and in a second displacement position, it rotationally connects the shaft to both the first and second gear wheels, and in a third displacement position, it rotationally connects the two gear wheels to each other while the shaft is rotationally decoupled from the two gear wheels.

  • Publication number: 20110297501
    Abstract: A dual clutch and a method for controlling the same in a drive train of a motor vehicle which has two friction clutches that transmit a torque from an internal combustion engine to respective transmission input shafts of a dual clutch transmission and which have a common counterpressure plate firmly connected to a crankshaft of the internal combustion engine and two contact plates that are fixed in terms of rotation relative to the counterpressure plate and can be moved axially by respective lever springs supported on a housing part firmly connected to the counterpressure plate. To limit the axial installation space for the dual clutch, the lever springs for actuating the friction clutches are actuated radially on the inside in the same direction by respective actuating systems in the case of a change from one friction clutch to the other of a torque to be transmitted via the friction clutches.
