    摘要： A steering drive system for a wheel side steered vehicle includes a coupling element couplable to output drives of the vehicle in order, when an amount of a superposition rotational speed of the coupling element is greater than zero, to provide at the output drives, which are driven at a basic rotational speed on the basis of a travel drive system of the vehicle, for steering the vehicle a superposition rotational speed which is to be superposed on the basic rotational speed. The system further includes at least one first electric machine whose rotational speed can be variably set or controlled, with a power summation and/or power branching unit, wherein a first connection of the power summation and/or power branching unit is coupled to a shaft which can be coupled, in particular via a defined transmission ratio, to a shaft of the travel drive system. A second connection of the power summation and/or power branching unit is coupled to the at least one first electric machine, and a third connection of the power summation and/or power branching unit is coupled to the coupling element, in particular via at least one defined transmission ratio.

    摘要： A gear reduction mechanism, particularly for use in an offset final drive unit for vehicular applications, has an input gear meshing directly with the output gear and two additional gear trains between the input and output gears. Three separate load paths therefore exist for the transmission of torque from the input gear to the output gear which means that the face widths of all the gears can be substantially reduced in comparison with a conventional single-mesh arrangement and the overall mechanism can therefore be of reduced width.

    摘要： A drive configuration for a skid steered vehicle comprises a pair of electric motors for propulsion of the vehicle, one each coupled to drive a respective track on a respective side of the vehicle, and one or more electric steer motors coupled through a differential gear mechanism to impose a speed difference between the tracks. An associated control system controls the current to each motor so that substantial contributions to the differential torque to turn the vehicle are made both by the steer motors and by the propulsion motors, in variable proportions preferably as a function of the vehicle speed.

    摘要： A steering system for providing steering control with a two path-split torque transmission in track laying vehicles and the like. One track driven through one transmission is controlled by both engine speed and engine power input and the other track driven through a second transmission is controlled via comparator means by steering input and track speed inputs of both tracks to provide the required speed difference between the tracks for full steering control independent of speed.
