摘要： A steering arrangement is provided for a work machine that includes a braking device, actuated by an actuation switch, to hold an operator input device in a predetermined position during operation. The braking force of the braking device can be overcome by the operator to make steering adjustments. The work machine may include a second steering arrangement on an opposite side of the work machine to improve operator visibility during close operation. A selector switch is used to select between one or the other steering arrangements.

摘要： A steering device for a motor vehicle is proposed, with an actuating member for the introduction of the steering movement and with a steering linkage to transfer the steering movement to the wheels. The device is characterized in that the actuating member consists of a nullsteering wheelnull (1) which is rotatable about a small angle and of a measured value transmitter (2) to generate an electrical or electronic position signal, and that the steering linkage is actuated by an adjustment drive which is controllable by an electrical or electronic regulating device as a function of the position signal.

摘要： Steering wheel return assist mechanism for use in a vehicle having a steering column assembly rotatably supporting a steering shaft comprises a spring operated return assist device which permits a limited degree of free rotation of the steering shaft before activation of the mechanism. The return assist device urges the shaft and the steering wheel to a near central neutral position after rotation of the steering wheel. In a second embodiment, a second return assist means structured substantially the same and spaced axially apart and inverted along the steering shaft from the first return assist means is disclosed so that the steering shaft is urged to a near central neutral position after the steering wheel has been turned in either direction.

摘要： A steering apparatus for artificially establishing steering feel in a steering system not having a mechanical connection between the steering wheel and the steerable wheels. The apparatus includes a hydraulic steering motor connected to the steerable wheels. A steering wheel position sensor and a steerable wheel position sensor each produce an electrical signal respectively indicative of the steering wheel position and the position of the steerable wheels. An electronic control unit monitors the sensor signals and controls a solenoid operated directional control valve to steer the vehicle in a direction and at a steering rate in response to the monitored signals. An electromagnetic friction brake is connected to a support and to the input shaft and is controlled by the electronic control unit to provide steering feel. The friction brake includes an armature fixed to the support and a brake member secured for rotation with the input shaft via a spline conneciton. The brake member is movable toward the armature under the influence of the magnetic field generated by the armature. The degree of mechanical coupling between the armature and the brake member is proportional to the magnetic field strength. Steering feel is controlled by the electronic control unit in response to the difference between the desired steering direction, as determined from the steering wheel position sensor, and the actual steering direction, as determined from the steerable wheel position sensor.
