  • Publication number: 20110136609
    Abstract: A drive train for a motor vehicle, which has a first and a second axle. The drive train has a first drive unit for permanently driving the first axle and an electric drive unit, which is arranged in the region of the second axle and has an electric motor. A shift clutch package contains a first shift clutch for setting up a first transmission ratio and a second shift clutch for setting up a second transmission ratio between the electric motor and an output of the electric drive unit. The electric drive unit is arranged parallel to an input shaft of a transverse differential of the second axle.

  • Publication number: 20090211824
    Abstract: An electric axle drive unit for an axle of a vehicle has an electric machine. The drive output of electric machine can be connected to the input of a transmission device. The electric drive unit has a differential gear, the input member of which is connected to an output of the transmission device. The output members of the differential gear can be connected respectively to a left-hand and a right-hand driveshaft of the axle. At least one transmission stage of the transmission device and the differential gear are arranged on opposite sides of the electric machine in the axial direction. The differential gear is connected to the transmission stage by means of a hollow shaft.

  • Publication number: 20090127059
    Abstract: A clutch arrangement (10) for a motor vehicle transmission (80) is proposed for connecting a shaft (12) to a rotational element (14), in particular to a freely moving wheel (14), which is mounted thereon, wherein the clutch arrangement (10) has: a sliding sleeve (22) which is connected in a rotationally fixed fashion to the shaft (12) and is mounted in an axially displaceable fashion on the shaft (12) between a closed position and an open position and has a first sliding toothing (24); a clutch element (26) which is connected in a rotationally fixed fashion to the rotational element (14) and has a second sliding toothing (28) into which the first sliding toothing (24) can be inserted axially in the closing direction (30) in order to connect the rotational element (14) to the shaft (12) in the closed position; and an actuator arrangement (40) for axially sliding the sliding sleeve (22).

  • Patent number: 6869379
    Abstract: An automatic variable-speed transmission for setting up a plurality of gear steps with an input shaft, an output shaft and two transmission units which form two parallel branches. One branch has a multi-step transmission and the other a summing transmission with a friction clutch for starting and for central synchronization, the friction clutch having a first friction element and a second friction element, one of the friction elements being connectable to various transmission elements by means of at least one shift element, with at least one first power command range for gear-step changes between low gear steps and at least one second power command range for at least the gear change into the highest gear step and for the highest gear step. In this case, the at least one shift element connects the one friction element to transmission elements such that there is reduced reactive-power flow in any operating mode.
