So is axially on both sides of the common locking device with the control piston 32 each Energy store 25 of the same size is provided, these energy stores cooperate with the locking device 32 to 36.
- the Locking devices are then jointly operated by the hydraulic pump 28 via the Valve 29 acted upon.
- the pressure chambers 27 are hydraulically relieved, press the Springs 25 each associated hydraulic piston 26 from opposite sides forth to the control piston 32, which then through the free ends of the guide tubes 30 in the center position of the reset bolt 24 already shown in FIG. 3 is moved.
- the then effective length of the reset device 21 again corresponds to the distance that the Have joints 22 when the wheel carrier 9 is in its basic position for straight travel has reached.
- the valve 36 is open and is after Completion of the actuating movement closed, so that the hydraulic locking of the Reset bolt 24 is secured.
- the reset device according to FIG. 2 or FIG. 3 can, however, also be constructed without Take on the additional function of the actuator 19. Then you need to the hydraulic chambers 33, 34 leading hydraulic lines 35 only via further controllable valves 37 and 38 to be connected to a pressure source. at When the valve 36 is closed, the hydraulic chambers 33 and 34 can then be separated pressurized hydraulic fluid are charged so that the reset bolt 24 via the control piston 32 depending on the pressure difference in the chambers 33, 34 can be forcibly adjusted. All that is needed is valves 37 and 38 according to the steering conditions for the wheel carrier 9 or the associated Rail wheels 7 to be controlled. These valves 37, 38 close automatically Failure of the control device responsible for the steering, so that only the Reset device is effective.
- the operational steering by an actuator 19 and the automatic reset of the wheel carrier 9 in the basic position with the automatic steering deactivated Application of the reset device 21 is also applicable when the to be steered Wheels 7 are individually pivotable about corresponding vertical axes. Then it's just everyone of these wheels 7 to be steered, an actuator 19 and a resetting device 21 assign, these components 19, 21 for one with tie rod (39) or hydraulic coupled pair of wheels also in a combined arrangement, in particular according to FIG. 3 can be executed.
