  • Patent number: 7252184
    Abstract: A transfer case (12) for distributing a driving torque of an input shaft (19) between two drivable output shafts (22, 29) is described. The transfer case (12) is realized with two controllable and adjustable frictionally engaged clutches (k_VA, k_HA), which are arranged between the input shaft (19) and the output shafts (22, 29) and whose transfer capabilities can be respectively adjusted via separate actuating devices (10, 11). A driving torque can be distributed between the drivable output torques (22, 29) in dependence upon the set transfer capabilities of the clutches (k_VA, k_HA). One clutch (k_HA) can also be radially enclosed by the other clutch (k_VA).

  • Publication number: 20070144808
    Abstract: A method for operating a drive train of a vehicle with a drive engine, a brake system, at least two vehicle cross-shafts of a first vehicle axle with at least two wheels. The cross-shafts being actively connected via a transverse distributor gear and being driven by the engine. The vehicle also possibly having a second vehicle axle with at least two wheels. Frictional shift elements of the first vehicle axle, between the wheels of the first vehicle axle and the transverse distributor gear, are provided for variable distribution, to the first vehicle axle, of the fraction of the drive torque from the engine in the transverse direction of the vehicle between the two wheels. A desired yaw torque is determined. The drive engine, brake system and shift elements are controlled such that the desired yaw torque is produced essentially without changing the positive forward drive of the vehicle.

  • Publication number: 20070034441
    Abstract: A power train and a method for controlling and regulating a power train of a motor vehicle with at least two drivable motor vehicle axles. A main transmission is arranged between a motor and the motor vehicle axles for representing various gear ratios. Furthermore, a controllable and regulatable clutch is provided between the main transmission and each of the motor vehicle axles, respectively, whose transmission capacity is respectively adjustable by means of an actuator system. A drive torque can be distributed between the motor vehicle axles as a function of the set transmission capacities of the clutches. The transmission capacities of the clutches can be adjusted to the distribution of the drive torque as needed and optimized as to efficiency by the actuator system such that one clutch can be operated in a slip operation, while the other clutch can be held at least nearly in a synchronous state.

  • Publication number: 20070015618
    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.

  • Publication number: 20060225982
    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.

  • Publication number: 20060173597
    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.

  • Publication number: 20060166786
    Abstract: A method for controlling a drive train of a vehicle having a a multi-group transmission, comprising an automatic transmission and a subsequently placed range group. During a change of the gear ratio of the range group, the following occurrences take place: the drive train is relieved of load by a change of motor torque; an openable shifting element of the range group is opened; an closable shifting element of the range group is synchronized and closed; one ratio of the automatic transmission is changed in such a way that a change of ratio of the multi-group transmission is smaller than is an unassisted change of ratio of the range group. A desired speed of rotation of the motor is established by changing the transfer capability of one shifting element to an equivalent ratio of the multi-group transmission, which ratio exhibits a connective rotary speed to which the closable shifting element of the range group is synchronous.
