  • Publication number: 20090288513
    Abstract: An arrangement of position transmitters on a selector rod for automatic speed change transmissions in motor vehicles, which interact with housing-mounted position sensors of an electrical speed detection circuit, at least one selector rod on its end regions being movably supported in cross walls of the housing of the transmissions and being actuated by means of a preferably electrohydraulically controlled speed selection unit where the selector rod projects through a through an opening in a cross wall of the transmission, which wall separates the oil compartment into the gear chamber which holds at least the speed selection unit and the position sensors, and the position transmitters are attached directly to the selector rod such that the selector rod with the position transmitters can be mounted through the through the opening as a mounting unit.

  • Publication number: 20090235771
    Abstract: A shift device for a speed change transmission in motor vehicles having at least one selector rod which is movably supported in the gear housing in cross walls, by means of which rod the transmission steps in the gear housing can be shifted. The selector rod on one end penetrates a cross wall of the transmission, which wall separates the oil compartment, and by means of a plastic sleeve, which is sprayed onto the selector rod, is guided and sealed in the corresponding through hole of the cross wall of the transmission.

  • Publication number: 20080276740
    Abstract: The invention relates to a drive unit comprising an internal combustion engine and a gearbox for motor vehicles, wherein for transmitting a torque to the transmission a crankshaft of the internal combustion engine is connected to a transmission-side element via a carrier plate. According to the invention, the carrier plate is designed in at least two parts with separate plate sections.

  • Publication number: 20070249456
    Abstract: The invention concerns a drive device for motor vehicles, comprising a drive assembly which acts via a differential gear on two output shafts, an arrangement being provided at the level of the output shafts, with a superposition gear connected therebetween, by means of which the drive torque from one output shaft can be transferred to the other output shafts. In order to provide a particularly effective drive device in terms of both control technology and functionality, it is proposed that the transfer arrangement be formed by at least one electric machine that can be switched to function as an electromotor and as a generator.

  • Publication number: 20060142119
    Abstract: The invention relates to a drive mechanism for all-wheel drive vehicles, comprising a variable-speed transmission and an interaxle differential for distributing drive torque onto a first and a second axle differential via which the front wheels and rear wheels of the motor vehicle are driven. A drive shaft of the variable-speed transmission drives a driving element of the interaxle differential while output elements of the interaxle differential are connected in a driving manner to the axle differentials. Also provided is a clutch which influences the output torque distribution.
