Abstract: An auxiliary transmission (31) with controllable clutch (2) is described for the optional distribution of a drive output torque to one or more drive output shafts with a reduction gear stage (3) and with a hydraulic pump (14). The hydraulic pump (14) is arranged on a transmission input shaft (4) and the reduction gear stage (3) is connected in series in such manner that the drive input power to the hydraulic pump (14) remains at least approximately the same when a range change takes place in the reduction gear stage (3).

Abstract: A method for controlling the driving stability of a vehicle comprising the steps of determining whether or not a curved path lies before the vehicle, if a curved driving path found to exist; determining the probable uncorrected “inherent” path (B), determining the specified “set” path (S), a comparison of the inherent path (B) and the set path (S) and determination of a deviation (x) in the controlled path taken; determining the distribution of a roll moment (ERCk) for at least a partial compensation of the deviation (x) from the path; realization of the determined roll moment distribution (ERCk) by the issuing of position signals (SMVA, SMHA) to a forward active stabilizer (2) for the changing of a forward support moment (MVA).

Abstract: A procedure is described for control and regulation of the dynamic-drive of a vehicle according to a set nominal value for the vehicle components affecting the dynamic-drive. The nominal value is set according to a driver's wish setting and with reference to a vehicle pattern stored in a control device. The measurable forces acting upon the vehicle are regulated and a controlled distribution of the longitudinal and lateral forces acting upon the tires of the vehicle is carried out among the tires.

Abstract: A steering system with at least one steering wheel actuator and at least one steering actuator which are connected to each other via a controlled system. Minimal steering impulses being superimposed in order to be able to determine the steering tie rod forces that occur.

Abstract: A reduction gear (3) of a multi-range transmission (1) for a vehicle, especially for an all-wheel vehicle, having at least two ratio steps. The reduction gear (3) is situated between a main transmission (2) and one output of the vehicle and designed with at least one parking lock device (22A, 22B) by means of which, in activated state, at least one part of the output can be stopped. The parking lock device (22A, 22B) is associated on the transmission output side with at least one output shaft (7, 8) so that the output of the vehicle in activated state of the parking lock device (22A, 22B) can be stopped even when the power flow is interrupted in a drive train in the area of the reduction gear (3).

Abstract: A distributor transmission (8) having at least three shafts (11, 12, 13) for distributing a drive torque (M_GE) as needed to at least two drive axles (4, 5). A first shaft (11) is operatively connected with the first drive axle (5) and can be loaded with the drive torque (M_GE). The second shaft (12) is operatively connected with the second drive axle (4) and a torque (M_E) of a machine device (14) on a third shaft (13) can be applied which influences a degree of distribution (P_VA/P_GES) of the drive torque (M_GE) between the drive axles (4, 5).

Abstract: A distributor gear (1) with an adjustable coupling device (5) for a vehicle, in particular for a vehicle with a shiftable all-wheel drive is described for the distribution of an incoming drive torque via a drive shaft (2) to at least two output shafts (3, 4). It is moreover provided that an output shaft (4) can be connected via the coupling device (5) with the drive shaft (2) and that the coupling device (5) can be actuated via an electric motor (9) and a drive converter device (10) located between the electric motor (9) and the coupling device (5) for the conversion of rotary movement of the electric motor (9) into a translatory actuation movement for the coupling device (5). The electric motor (9) is incorporated into a gear (7).

Abstract: A transfer case (1) with controllable clutch (5) for a motor vehicle, especially for a motor vehicle with part-time four-wheel drive, for distributing a driving torque coming in via a drive shaft (2) to at least two output shafts (3, 4). Hereby the output shaft (4) can be connected to the drive shaft (2) via the clutch (5), and the clutch (5) can be actuated via an electric motor (9) and a drive converter device (10) that is arranged between the electric motor (9) and the clutch (5) for converting a rotatory motion of the electric motor (9) into a translatory actuating motion for the clutch (5). The electric motor (9) is hereby designed as an induction motor.
