  • Patent number: 5119303
    Abstract: Brake-force control system (ABS) for vehicles, in particular motor vehicles, with separate control of the front wheel brakes and with joint or separate rear wheel brakes which can be switched over to "select high" control or individual control and/or with a limited-slip differential at the rear axle, the switchover of the rear wheel brakes and/or of the limited-slip differential being effected at different coefficients of friction (.mu.-split) with a specifiable rate of rise dependent on the travelling speed, and in which, in order to increase directional stability during a braking procedure, a switching device is provided which blocks a switchover of the rear wheel brakes and/or of the limited-slip differential until the travelling speed from the time of the detection of different coefficients of friction has decreased to a specified value, the rate of rise of the switchover being dependent at least one the duration of the reduction of the vehicle speed to the specified value.

  • Patent number: 5065835
    Abstract: A motor vehicle with four driving wheels and driven differential gearing for the drive, where (in the case of rotational-speed differences occurring between the wheels) a control device intervenes to distribute the drive power of an engine to the permanently driven wheels and/or the other driven wheels. This intervention occurs for a particular holding time which is progressively extended if a new intervention by the control becomes necessary after a test disconnection of the respective intervention. In addition, or alternatively, the control device can respond more sensitively and thus more quickly to rotational-speed differences of the wheels which may later occur during, or after, a test disconnection.

  • Patent number: 4522418
    Abstract: In motor vehicles, in particular passenger cars possessing an axle or axles with steerable wheels, the steering-gear box is conventionally located asymmetrically with respect to the center-line. The result of this on the steering linkage is that the linkage part-sections between the steering-gear box and each of the wheels are of different design. This asymmetry can give rise to differences in the wear of the tires on these wheels, and is advantageously avoided according to this invention by making the overall stiffness values of the two part-sections identical, irrespective of the design-differences.

  • Patent number: 4423883
    Abstract: A steering arrangement for motor vehicles wherein two steerable wheels are coupled with a steering gear arm which is connected to a steering column. The steering gear arm is divided into at least two parts with one part of the steering gear arm being associated with each steerable wheel. At least one sun gear is mounted to the steering column which mates with planetary gears of a pair of planetary gear carriers. The planetary gear of each planetary carrier mates with an outside gear which forms a secondary drive for a part of the steering gear segment arm. A locking device is provided in order to enable an alternative locking of the planetary gear and the outside gear.
