- the opening pressure of the first and second check valves may, for example, be lower by 1.5 bar than the corresponding opening pressures of the third and fourth check valves. Even with the first and second check valves, the opening pressure is To keep low as possible, since here too throttling losses affect the efficiency negative.

- FIG. 1 shows the actual state of a standard system.
- Pressure supply unit is a suction-throttled radial piston pump 1, which provides two different pressure levels via a cascade connection by means of two proportional pressure limiting valves 3 and 5, which are called Achstikbegrenzungsventi- Ie and are connected as pressure differential valves.
- the pressure levels are monitored by pressure sensors 7, 9.
- the pressure ranges are each for a front hydraulic device 25, for example, a pivot motor 27 on the stabilizer of the front axle with 11 for the right side and 13 for the on the left side, for a rear hydraulic device 29, for example a swivel motor 31 on the stabilizer of the rear axle, corresponding to 15 and 17.
- the pressure on the rear axle must always be lower than the pressure on the front axle.
- the operation of the direction switching valve 19 is monitored by means of a circuit detection sensor 21.
- a fail-safe valve 23 is arranged on the front axle, which serves to block the swivel motor 27 of the front axle in the fail-save case when a valve is clamped or in the event of a power failure, and to depressurize the swivel motor 31 in the rear axle.
- two Nachsaugventile 33 and 35 are attached, each of which can connect the pressure range 11 and 13 of the swing motor 27 on the front axle via a tank line with the tank 37, in such a way that a throttled free swinging of the swing motor 27 on the leakage position of Swing motor can be done even by sucking in the flow without cavitation problems.
- the basic approach of the present invention is that it dispenses with cost-intensive elements. It is specifically about the reduction of electromagnets from directly controlled valves.
- the directional changeover valve may be controlled by a first hydraulic manipulated variable formed at least from one of the pressure levels 11 to 17.
- An essential feature of the present invention is that the switching magnet of the direction changeover valve 19 can be omitted.
- FIG. 2 shows a hydraulic circuit diagram of a roll stabilizing device according to the invention for a single-axle system, for example for a front axle of a motor vehicle.
- the saving of the solenoid is achieved according to the embodiment shown in Figure 2 in that a first control line 39 and a second control line 41 are provided, via which the first pressure level 11 of the front axle right and the second pressure level 13 of the front axle left returned to the direction changeover valve 19 become.
- the direction changeover valve 19 is designed as a 4/2-way valve 43.
- the direction changeover valve device 19 or the 4/2-way valve 43 has a first control chamber 45 which is assigned to the first control line 39 and via a second control chamber 47 which is assigned to the second control line 41.

- the pressure difference between the first pressure level 11 and the second pressure level 13 corresponds
- the resulting signal corresponds to a movement of the control of the 4/2-way valve 43, as seen in the orientation of Figure 2, to the right or left.
- the control of the 4/2-way valve is so long as a corresponding pressure difference in the control lines 39 and 41, moves in one direction until the control is in an end position corresponding to one of the two switching points.
- the circuit detection sensor 21 monitors the position of the control element and can forward it to a central control unit, not shown in FIG. 2, which can detect a malfunction of the system, in particular by evaluating further signals, for example to switch the fail-safe valve 23, which in the exemplary embodiment according to Figure 2, only the only front hydraulic device 25 is blocked.
- the radial piston pump 1 can supply a front right chamber 51 or a front left chamber 53 with hydraulic energy via a first supply line 49.
- the first supply line 49 is continuously connected to the front right chamber 51 of the swing motor 27 of the front axle.
- the pump supply line 49 opens into a first supply line 55, which controls the front right chamber 51 or in a second supply line 57, which controls the front left chamber 53.
- a total of four check valves are connected, wherein the first supply line 55 has a first check valve 59 which automatically opens to supply the front right chamber 51 with hydraulic energy, that is, if the radial piston pump 1 via the supply line 49 and the first supply line 55 is connected to the front right chamber 51.
- the opening pressure of the first check valve 59 may be, for example, about 0.5 bar.
- the second supply line 57 has a second check valve 61.
- the check valves 63 and 65 have a higher opening pressure, for example, 2 bar than the first and second check valves 59 and 61.
- the third check valve 63 limits the control pressure acting on the second control chamber 47, for example to 2 bar.
- the pressure generated by the incipient rolling motion which is utilized as control pressure, ultimately leads to a control movement of the control of the 4/2-way valve, in the illustration of Figure 2, to a movement to the left, which has the consequence that the previously unpressurized first supply line 55 is now connected to the pump supply line 49, ie with the radial piston pump 1.
- the front right-hand chamber 51 of the swivel motor 27 is supplied with hydraulic energy, whereby the incipient rolling movement can be counteracted automatically by an adjusting movement of the swivel motor 27.
- the adjusting movement is continued until an opposing pressure difference is established, that is, for example, the turning of the vehicle is completed, whereby now in the front left chamber 53, a higher pressure sets, so that in turn the 4/2-way valve again moved back into the position shown in Figure 2, so makes the control action automatically reversed.
- Figure 3 shows another embodiment of a roll stabilization device for a two-axle system with a front axle and a rear axle, wherein a hydraulic control variable is tapped on a hydraulic device 29, for example a pivot motor 31 of the rear axle.
- Figure 4 shows a hydraulic circuit diagram of a roll stabilization device for a two-axle system with a front axle and a rear axle, wherein a hydraulic control variable a front hydraulic device 25, for example, a pivot motor 27 of the front axle, is tapped.
- FIG. 5 shows a hydraulic circuit diagram of a roll stabilization device analogous to the illustrations in FIGS. 3 and 4, wherein the hydraulic manipulated variable at the front hydraulic device 25 and at the rear hydraulic device 29 is tapped as a difference.
- the hydraulic circuit diagrams according to FIGS. 3 and 5 correspond in their basic features to the hydraulic circuit diagram 1 according to the prior art. In this respect, reference is made to the description of Figure 1.
- the 7/2-way valve 19 is hydraulically actuated via the control lines 39 and 41.
- the control as shown in the hydraulic circuit diagrams according to FIGS. 3 and 4, takes place analogously to that described in FIG. In this respect, reference is made to the description of Figure 2.
- the front hydraulic device 25 and the rear hydraulic device 29 are each assigned a set of non-return valves 59 to 65 in the mode of action described in FIG.
- the control lines 39 and 41 each have a fork, namely a first bifurcation 67 and a second bifurcation 69.
- the control lines 39 and 41 branch respectively to the front hydraulic unit 25 and to the rear hydraulic unit 29th
- the first control line 39 branches into a first rear control line 71, which picks off the pressure level 17 of the rear axle on the left and into a first front control line 73, which taps off the pressure level 13 of the front axle on the left.
- the second control line 41 branches into a second rear control line 75, which taps off the pressure level 15 of the rear axle on the right and into a second front control line 77, which taps off the pressure level 11 of the front axle on the right.
- the maximum value of the prevailing in the respective branched control lines pressures is formed. This can advantageously be exploited to the effect that already a scheduling of one of the axes leads to a control intervention.
- the generated by the corresponding hydraulic devices control flow rates are added. This leads to a faster filling of the connected control chambers 45 and 47 of the 7/2 way valve 19, so also to a better response of the 7/2 way valve 19, thus the entire anti-roll control. So it can an anti-roll controller with an overall shorter response time can be realized.
- the first rear control line 71 and the second rear control line 75 may each have a check valve 79.
