摘要： The maximum operating pressure for the fluid servomotor of a fluid power operated steering system is varied as a function of steering displacement by varying the spring prestress bias on a relief valve controlling fluid discharge from the operating chamber of the fluid servomotor. The valve spring prestress is controlled by a spring engaged plunger that is displaced relative to the servomotor piston during steering displacement.

摘要： In a power steering system having hydraulic power support for motor vehicles, a steering gear shaft having a steering wheel is connected to an input element of a steering gear. An output element of the steering gear is connected to wheels of the vehicle to be steered. Two working chambers of a servo motor of a power boosting system can be supplied with a hydraulic medium from a servo pump through a steering valve in accordance with a torque applied in the area of the steering gear shaft input element. Two sensors for detecting an angle of rotation and a torque are provided on the steering gear shaft and on the output element of the steering gear accordingly. After the steering wheel has been released after a steering operation, the wheels to be steered and the steering gear can be returned with hydraulic support. Both the intensity and direction of the hydraulic power support as well as the returning of the wheels to be steered are controlled by a common, electronically controlled electromagnetic valve. In addition, only one steering force sensor and/or torque sensor is provided for detecting the steering force. With this sensor, the control distances can be reduced greatly, thus yielding a high steering accuracy.

摘要： The invention relates to an auxiliary power steering system, especially for motor vehicles having a double acting servocylinder with two working chambers and a servopiston. A hydraulic steering limitation device has a valve that coacts with the servopiston responsive to a predetermined extent of power stroke to open a flow path from the pressurized working chamber to the tank connected working chamber to promptly stop the power stroke leaving the servopiston in position for prompt reversal of steering direction under pressure power. A stationary flow channel member extends the substantial length of the servocylinder and passes through a bore in the servopiston with which it has a sliding relationship. At a predetermined end of a power stroke, bores and a passage in the channel member communicate with the working chambers of the servocylinder to equalize the pressure at tank pressure for stopping the power stroke.

摘要： The piston and cylinder of a hydraulic power booster are provided with opposed longitudinal grooves effecting a pocket for a series of rollers axially aligned and on an axis parallel to that of the piston-cylinder axis. A leaf spring in the piston groove maintains a radial bias on the rollers towards the cylinder groove. The rollers effect a sliding guide or key between the piston and cylinder to prevent rotation or twisting of the piston in the cylinder.

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： This invention relates to a pressure turnoff device in the terminal positions of the steering deflection in an auxiliary power steering. In steering systems that reveal a working piston (2) that can be shifted in the steering housing, one inserts this turnoff device in a passage borehole (17) of working piston (2). For each steering direction, one provides a turnoff valve (20, 22 or 21, 23) which can be activated by a plunger (24 or 25) that bumps into a wall (30 and 31). To avoid any time consuming adjustment work on the turnoff valves (20, 22; 21, 23), the walls (30 and 31) contain screwed-in bolts (40 and 41) with pressed-on sleeves (32 and 33), with the sleeves working as stops. After installation of the auxiliary power steering in the vehicle, one can automatically press the sleeves (32 and 33) into the terminal position corresponding to the wheel steering angle. This is done in that, after preassembly of the sleeves (32 and 33), upon the bolt (40 and 41), and after screwing the combination thus created into housing (1), with the front axle jacked up, one first of all steers against the wheel stops without auxiliary power. In the process, one can press sleeves (32 and 33), by means of working piston (2), upon bolt (40 and 41) to the degree provided for the turnoff of the auxiliary power. Because the plungers (24 and 25) of the turnoff valves (20, 22; 21, 23) stick out of working piston (2) by dimension "x," the auxiliary power is turned off shortly before reaching the wheel deflections.

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： The invention is concerned with a device that cuts off pressure in the final positions of the steering movement in an auxiliary-power steering device. In steering devices that have movable working pistons in the steering gear housing, this cut-off device is installed in a through drilled hole in the working piston. A by-pass valve that is activated by a push rod touching the wall of the housing is provided for every direction of steering. To avoid time-consuming adjustment work on the by-pass valves the walls contain bushings located opposite the push rods that are automatically pushed into the final positions corresponding to the wheel steering angle after the auxiliary-power steering device is installed in the vehicle. That happens as a result of rotating, first without auxiliary power, against the wheel limit stops, with the front axle jacked up, after the preliminary installation of the bushings in their drilled holes. When that happens, the bushings are pushed in by the working piston to the setting (a) that is provided for cutting off the auxiliary power. Since the push rods of the by-pass valves are larger than the depth (s) of the drilled hole in the bushings by the amount of the setting (a), the auxiliary power is cut off shortly before the wheel limit stops are reached.

摘要： A power steering system has a servomotor flow control valve with means for automatically returning the vehicle to straight ahead position by hydraulic power. This is accomplished in a construction utilizing a piston valve linked by a cam mechanism to movement of a servomotor piston in such manner that, responsive to movement of the servomotor piston, and upon return of the piston valve to a neutral position a brief overtravel beyond neutral position occurs which reversely pressurizes the servomotor to straighten the wheel direction after a turn.

摘要： A compact construction for a vehicle steering gear is provided of the rotary valve type which utilizes a torque rod having an end connected to a worm shaft and the opposite end connected to a steering spindle wherein axial load oil pressure on the torque rod is minimized to avoid breakage. This is accomplished by hydraulic circuitry which routes high inlet pressure to the valve housing directly to the valve grooving instead of to an end of the valve body where it would exert an axial force on the torque rod.
