  • Patent number: 8419579
    Abstract: A transmission device, for a motor vehicle, with at least two drive output shafts and two multi-shaft planetary gearsets in active connection with one another. A shaft of a planetary gearset is actively connected with an output shaft and is shifted, between first and second power paths, such that in the first power path, torque of an electric machine is transmitted in equal parts and with the same sign to the output shafts, and in the second power path, torque is transmitted in equal parts but with different signs. One of the two planetary gearsets is made as a four-shaft, reduced coupling transmission with two sun gears and a common planetary gear carrier with radially inner and outer planetary gears that mesh with one another, and which are engaged, on the one hand, with the sun gears and, on the other hand, with a rotationally fixed ring gear.

  • Patent number: 8308600
    Abstract: A transmission device with at least two output shafts and at least two multi-shaft planetary gearsets being actively connected. A shaft of each gearset can be actively connected with an output shaft. A shifting mechanism is provided, between the two output shafts, for shifting between a first power path and a second power path. In the area of a further shaft of one of the planetary gearsets, torque from an electric machine flows along the first or the second power path. When the first power path is engaged, the torque from the electric machine flows in equal parts and with the same sign to the two output shafts, and when the second power path is engaged, the torque flows to the two output shafts in equal parts but with opposite signs. A motor output shaft of the electric machine is arranged perpendicularly to one of the two output shafts.

    Abstract: A transmission device with at least two output shafts and at least two multi-shaft planetary gearsets that are actively connected with one another. A shaft of a planetary gearset can be actively connected with an output shaft. In addition, a shifting mechanism, located between the two output shafts, shifts between a first power path or a second power path. In one of the planetary gearsets, torque from an electric machine can be transmitted along either the first or the second power path. In the first power path, torque from the electric machine is transmitted to the two output shafts in equal parts and with the same sign. In the second power path, torque is transmitted to the two output shafts in equal parts but with opposite signs. The planetary gearset, in the area of which the torque from the electric machine can be transmitted, is a simple negative planetary gearset.

    Abstract: An apparatus for actuating a form-locking shift element which can at least be shifter between two shifting positions, of a transmission device having a drive device and a drive converter device for converting rotational drive motion of the drive device into translatory motion of the form-locking shift element. Two transmission shafts are interconnected, by way of the shift element, in a rotationally fixed manner in one shifting position, and are decoupled from one another in another shifting position. The drive converter device comprises a first component having at least one control curve, and a second component that is operatively connected to the first component which, in the region of the control curve, are connected to a component of the form-locking shift element, which is connected to one of the transmission shafts in a rotationally fixed manner and is axially displaceable.

  • Patent number: 7500931
    Abstract: A vehicle with a drive engine, with at least two vehicle axles and a transmission unit for variable distribution of drive torque from the drive engine in the vehicle's longitudinal direction between the vehicle's axles. The transmission unit is made with an input shaft and at least two output shafts, at least two planetary gearsets and an electric machine arranged between two mutually connected shafts of the planetary gearsets for distribution of the torque delivered via the transmission input shaft between the transmission output shafts as a function of a torque produced by the electric machine. The electric machine is in active connection with the transmission unit connecting between the two interconnected shafts of the planetary gearsets and the planetary gearsets are made with different transmission ratios so that the electric machine is driven by virtue of a speed difference between the actively interconnected shafts of the planetary gearsets.

  • Patent number: 7500933
    Abstract: A transmission for distributing a drive torque to two drive output shafts, with two planetary gearsets each having at least three shafts. A respective shaft of a planetary gearset is connected to a drive input shaft. Furthermore, one shaft of each planetary gearset constitutes one of the output shafts and in each case at least one further shaft of a planetary gearset is connected with a shaft of another planetary gearset. An operation-status-dependent torque of one shaft can be supported by the connection, depending on an operating status of the other shaft connected thereto, in such manner that when there is a rotation speed difference between the output shafts, a speed-difference-changing torque is applied to the planetary gearsets. Furthermore, a drive train is proposed, in which a drive torque from a drive-power-source is distributed variably in the longitudinal and transverse direction of the vehicle in an operation-status-dependent manner.

  • Patent number: 7479088
    Abstract: A transmission for distributing a drive torque between at least two drive output shafts with at least two planetary gearsets, each having at least three-shafts. In each case, a shaft of a planetary gearset is connected to a drive input shaft and a second respective shaft of a planetary gearsets is the drive output shafts. A respective third shaft of the planetary gearsets communicates with a brake such that a degree of distribution of the drive torque between the two output shafts varies as a function of the transfer capacities of the brakes. A transmission device controls and regulates a drive torque from a drive engine between the two output shafts of the transmission device. The transfer capacities of the two brakes are adjusted such that one brake is in a synchronous condition and the transfer capacity of the other brake is varied between a lower and an upper limiting value.

  • Patent number: 7418327
    Abstract: A method for determining a control standard of an active steering device (10) of a vehicle (1) controllable by a control device (11). A driving dynamic of the vehicle (1) is influenced according to the control standard. The control standard is determined according to a nominal yawing rate calculated at least with reference to different actual operating parameters of the vehicle and one dynamic vehicle state determined according to the nominal yawing rate and actual operating state parameters. The control standard is superimposed on a steering transit angle preset by a driver so that an existing actual yawing rate is changed in direction of the nominal yawing rate.

  • Patent number: 7344475
    Abstract: A method for controlling of a drive train of a vehicle having a multi-group transmission, an output mechanism and a control apparatus for the regulation of the drive train. The multi-group transmission consists of an automatic transmission and a range group. To change the ratio of the range group the drive train is relieved of load; a shifting element of the range group is closed; a shifting element of the range group is synchronized and opened; and a ratio of the automatic transmission is so altered that a change of the ratio of the multi-group transmission is less than in a case of an individual alteration of the ratio of the range group.

  • Publication number: 20080051958
    Abstract: A process for controlling and adjusting an active chassis system (1) of a vehicle having a sensor device (2) and at least one element (3, 4, 5) for acquiring vehicle accelerations of the chassis system (1). The mode of operation of the one or more elements (3, 4, 5) is modified by a control device (6) which is in operative connection with the sensor device (2) such that subframe oscillations occurring while driving are minimized. Torsional oscillations of the body are determined by the sensor device (2) and the control device (6). The mode of operation of the element (3, 4, 5) is adjustably controlled by the control device (6) to counteract the calculated torsional oscillations of the body.
