Abstract: A power train for a vehicle comprising an engine with an output shaft; a transmission disposed on a centerline having a drive input disposed laterally on a first side of the centerline and a drive output disposed laterally on a second side of the centerline opposite of such first side; a first differential having an input shaft aligned with and connected to the drive output of the transmission, a first output shaft projecting through an opening in the transmission and a second output shaft; a first transversely disposed axle having a second differential; a second transversely disposed axle having a third differential; a first drive train interconnecting the engine output shaft and the transmission drive input; a second drive train interconnecting the first output shaft of the first differential and the second differential; and a third drive train interconnecting the second output shaft of the first differential and the third differential.

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.

Abstract: Power train for a motor vehicle, having an engine with a driven shaft which has a crankshaft axle which is located longitudinally to the direction of travel and which is connected to a starting unit, a preliminary gear stage with an input shaft and an output shaft, the input shaft of the preliminary gear stage being connected to the starting unit and the output shaft of the preliminary gear stage having a lateral offset to the crankshaft axle, a variator which is preferably made as a disk variator with two adjustable disk sets for the continuous transmission of torque, and for which the input-side disk set is connected to the output shaft of the preliminary gear stage, while the output-side disk set is located laterally offset, a subsequent gear stage which has an input shaft and an output shaft and which is located on the same side of the variator as the preliminary gear stage, the input shaft of the subsequent gear stage being connected to the output-side disk set of the variator, and a first differential w

Abstract: The invention relates to a hybrid drive apparatus for motor vehicles, having an internal combustion engine and an electric drive motor which act connected in series on at least one driven shaft which drives an axle differential. To achieve a drive apparatus which is favorable in efficiency and installation size, it is proposed that in addition, by means of transmission stages, there is at least one constant gear which, bypassing the electric drive motor, selectively drives the driven shaft from the internal combustion engine.

Abstract: The invention relates to a propulsion system for all-wheel drive motor vehicles, having a device for propulsion distribution to the front and the rear differential which transmit the drive output to the wheels assigned at the time, and with a device for coupled, variable distribution of the propulsion forces in the transverse and longitudinal directions of the vehicle depending on the operating situation of the vehicle for influencing the driving behavior, especially for improving the driving agility and driving stability.

Abstract: The invention relates to a method and a device for suppressing transmission noise from automatic transmissions, in particular for motor vehicles, the transmission having at least two alternating multi-disk clutches that control a power flow via a gearing mechanism through which oil flows to cool the clutches and to reduce wear and tear on them. To create a method and a device that are of simple design and that can operate without wear and tear, it is proposed that under defined operating conditions of the transmission, the throughput amount of oil is increased in such a way that a defined drag torque occurs at the multi-disk clutch that is opened.

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.
