摘要： The present invention relates to a method for steering a vehicle (1) with steerable front and rear wheels (2, 3), in which the angle (.beta.) of the rear wheels (3) is set as a function of the steering angle (.alpha.) of the front wheels (2) and other parameters. The displacement of the rear wheels (3) during start-up and steering out of forward travel follows the steering movement of the front wheels (2) with a time delay. Such a steering characteristic prevents a corner (5) of the rear of the vehicle which is on the outside of the turn from running over a laterally placed obstacle, for example a curb, when starting up.

摘要： In multifront and rear steering systems a problem exists due to fluid leakage which causes lack of synchronization in return to straight ahead steering position between the front and rear steering linkages causing inaccurate centering of the rear steering linkage in response to manual control of centering of the front steering linkage, where the front steering power is hydraulic and the rear steering power is hydrostatic. The invention provides the particular novelty of a centering device for the rear wheel steering linkage responsive to directional manipulation of the front wheels at the will of a driver from a steered position to a straight ahead position. In one embodiment a power steering cylinder is coupled to the rear steering linkage for effecting steering movement or return. Also connected to the rear steering linkage is a cylinder having a locking device and the centering device connected to actuate the rear steering linkage pursuant to automatically operating circuitry, within the skill of the art. A second embodiment combines the rear power steering cylinder with the locking device and centering device in a single housing.

摘要： An auxiliary power steering mechanism has a rotary valve that includes a rotary member integrally formed with the steering shaft of the vehicle and a fixed valve sleeve integrally formed with a threaded spindle. The rotary member contains a plurality of radial hydraulic fluid return bores arranged in two parallel rows with the bores of each row being spaced longitudinally. A guide groove in the valve sleeve, which is connected with a power cylinder, is assigned to each row of bores. An additional radial return bore is arranged in the middle of the two rows of bores and has a fixed residual cross section. All of the return bores include flat portions of different circumferential lengths to control the build-up of pressure in a surge chamber. The hydraulic return cross section produced by the bores is varied by a piston valve arranged in a concentric bore in the rotary member. The piston valve can be adjusted as a function of a pressure in accordance with speed. Operating forces at the steering wheel that are synchronized with the drive situation at the moment are obtained by changing the cross section of the row of bores in an open operating condition at that moment for setting the pressure of the rotary valve.

摘要： An auxiliary power steering mechanism with a working piston installed in the steering gear has a rotary valve comprising a rotary member and a fixed valve sleeve. A piston valve is inserted in a bore provided in the rotary member. The piston valve is connected with an adjustment device, such as an electromagnet, via a tube supported by a torsion bar. The electromagnet adjusts the piston valve as a function of various influencing variables such as speed, and controls the condition of a plurality of hydraulic fluid flow return bores arranged in longitudinally spaced relation in the rotary member for noise-free control of the build-up of pressure in a surge chamber that is active at the moment. The bores have flat portions of different contours and circumferential lengths.

摘要： A steering shaft especially for a motor vehicle has a torque-induced operative connection of a steering handling device with a steered wheel with a first shaft and with a second shaft, the shafts being connected torque-induced over a shaft joint with movavable joints. In order to create a steering shaft, the shaft joint of which achieves a large range, over which the deflection angle can be adjusted in all directions, while, at the same time, rotational nonuniformities of the steering shaft are minimized, the shaft joint is fixed at a component, which is attached to the vehicle, so that it can be swiveled approximately about the joint center with a device for the pivotable mounting of the shaft joint.
