摘要： In a rack servo-steering, particularly for motor vehicles, an inclined toothed pinion wheel (2) which is axially movable in a steering box (1) is in connection with a rack (4). An axial displacement of the pinion wheel (2) takes a steering device (14) out of its neutral position by opposing the force generated by centering springs (10, 29, 30, 33). The arrangement of said device provides for a median centering without play. The steering device (14) is comprised of two inlet seat valves (15, 16) and of two exhaust seat valves (17, 18) which are parallel to the pinion wheel (2) in the axial projection area of the pinion wheel (2) inside the steering box (1). The seat valves (16, 17, 18) and a centering spring (33) are arranged so as to be outside the rack area. This arrangement enables to provide a short construction of the steering with few hydraulic losses.

摘要： A pressure medium control unit for a servo steering, particularly for motor vehicles, has a valve body (1) with two control valves (8, 9) which rotate when the steering wheel rotates about the axis of the valve body (1). Both pistons (6, 7) of the control valves (8, 9) may be displaced by driving pins (4, 5) arranged at the fork end of a steering shaft and engaged with the pistons (6, 7). Due to the force of the springs (22, 23), the pistons (6, 7) are held on one side against the driving pins (4, 5). The contact lines (25, 26) between the driving pins (4, 5) and the valve pistons (6, 7), as well as the rotation axis of the fork end of the steering shaft are in one plane (E).

摘要： In an electrically supported rack and pinion servo-assisted steering system, an electric motor (8) is controlled by a signal from a torque meter. To prevent faulty steering, a safety circuit (28) containing two switches (25, 26) actuated by a lever (24) is provided. A ball nut connected to the rack of the rack and pinion steering gear is connected through a ball circulation circuit with a threaded spindle (11). The threaded spindle (11) is connected through spring (17) to an output part (16) of a clutch (12), which can be coupled to and decoupled from the electric motor (8). The threaded spindle (11) slides axially on the output part (16) and rotates with it. The threaded spindle (11) is connected through two elastic intermediate rings (19, 20) and two axial bearings (21, 22) to the stationary housing (13) on which it slides axially and on which it can rotate. If in the event of faulty steering the axial displacement does not correspond to the torque on the steering wheel, one of the two switches (25, 26) opens the clutch (12).

摘要： A device for steering the rear wheels (6) of vehicles with steerable front and rear wheels has a rotating field motor (2) for supporting the rear-wheel steering system. Said rotating field motor (2) is controlled by a central electronic control unit (15) in function of the position of the front wheels. The control of the rotating field motor (2) is therefore effected in very small steps which are immediately notified back to the central control unit (15). Only when the signals sent back about the small steering steps completed coincide with the command signals emitted by the control unit (15) for the small steering steps is an enabling signal emitted for further operation of the rotating field motor (2). If the signals sent back deviate several times in a row from the command signals for the small steering steps, the rotating field motor (2) is switched off and a locking device (20) is set on its blocking position.

摘要： An electric motor drive unit for actuating an electromechanical rear-wheel steering device for motor vehicles has an electric motor (2), the drive shaft (3) of which is connected to a device for moving the rear wheels. A freewheel (7) acting in both directions of rotation is provided to immobilize the drive shaft (3) and hence to block the rear-wheel steering. The freewheel (7) has an outer ring (8) and a hub (6) arranged concentrically therewith and connected to the drive shaft (3) of the electric motor (2). The peripheral surface (12) of the hub (6) is cylindrical and the inner running surface of the outer ring (8) has several clamping surfaces (13). Between the outer ring (8) and the hub (6) there are several rollers (10) guided in a cage (11). The freewheel can be blocked by an actuating pin (15) pressed by a spring (17) against one of the rollers. The freewheel can be released by a lifting solenoid (20) acting on the actuating pin (15) in the opposite direction to the spring (17).

摘要： Proposed is a process for producing a stator winding for electrical machines intended mainly for use in motor vehicles. The process shows how a winding (12) pre-fabricated in coil branches (3, 13, 14, 15) lying entirely outside the stator-plate assembly (6) can be introduced in a single operation into the grooves (4) in the stator-bundle of laminations (6). Further embodiments show how the stator winding disclosed can be designed as a compact unit with a satisfactory space factor.

摘要： In a servo-steering system for motor vehicles with a reaction which varies with the speed of the vehicle, the reaction is controlled by an electronic control unit (5). Here there is a pilot lamp (8) which indicates the lack of a tachometer signal when the vehicle is started. The pilot lamp is not extinguished until the electronic control unit (5) recognises and indicates a movement of the vehicle through a tachometer signal. The illumination of the pilot lamp (8) warns the driver of possible danger which may arise through the fact that the steering remains light even at higher speeds.

摘要： A current-regulating circuit controls the supply current of a magnetic coil in function of a pulsed voltage which is modulated by a modulator in function of a reference voltage and an actual voltage. A measuring device determines the feed voltage by means of a first measurement resistance on the positive potential side of the magnetic coil and the freewheeling current by means of a second measurement resistance parallel to the magnetic coil, and adds the voltage signals, which are proportional to the current. It then feeds the signals to the modulator, which regulates the current. A redundant second power transistor ensures that the current-regulating circuit itself functions even if the first power transistor fails. An additional short-circuit protective circuit protects the current-regulating circuit from accidental faulty connections and from short circuits in the conductors.

摘要： A steering device for steerable front wheel (3) and rear wheels (10) of vehicles has a front wheel steering system (1) and a hydraulically assisted rear wheel steering system (6). A electric signals from a front wheel steering angle sensor (11), rear wheel steering angle sensor (12) and a road speed sensor (14) are processed in an electronic control unit (15) in order to permit an electrical actuation of a control valve (16) of the rear wheel steering system (6). The reduction ratio of the steering lock of the front wheels (3) and rear wheels (10) is modified in function of vehicle speed. In addition to the electric control signals, a control valve (16) receives hydraulic control signals from a master-cylinder (17) in kinematic connection with the front wheel steering system (1), for the control of the steering motor (7) of the rear wheel steering system (6).
