- Figure 3 is a schematic view of a detail of the rail vehicle to explain the stability control in the second frequency range.
- Figure 1 shows - in a view from below, ie from the direction of the track bed - part of a rail vehicle according to the invention 101 with a car body 102, which is supported on an active chassis in the form of a bogie 103.
- the bogie 103 comprises a bogie frame 104, a first wheel unit in the form of a first gearset 105 and a second wheel unit in the form of a second gearset 106.
- the bogie frame 104 is on a first primary suspension 107 on the first gear 105 and a second primary suspension 108 the second wheel 106 supported.
- a first actuator 109 acts between the first gearset 105 and the bogie frame 104
- a second actuator 10 acts between the second gearset 106 and the bogie frame 104.
- the respective actuators 109, 110 on the one hand on the bogie frame 104 and on the other hand articulated on one of the wheel bearing housing of the associated wheelset 105, 106.
- the two actuators 109, 110 actively generate turning movements of the associated wheel set 105, 106 about a vertical axis of the rail vehicle 101 running perpendicular to the plane of the drawing of FIG. 1.
- the two actuators 109, 110 actively influence the turning angle of the associated wheel set 105, 106 in other words about a perpendicular to the plane of the drawing of Figure 1 extending vertical axis of the rail vehicle 101st
- the respective actuator 109, 1 10 on the associated wheelset 105, 106 generates a turning moment about the vertical axis of the rail vehicle 101.
- the second component of the couple on the respective wheelset 105, 106 applied by the supporting force, which acts on a corresponding articulation point (stops, etc.) of the respective opposite wheel bearing housing on the bogie frame 104.
- a plurality of actuators may be provided per wheelset, as is indicated in Figure 1 by the dashed contours 1 1 1, 112.
- the actuators 109, 110 are shown in FIG. 1 for the sake of simplicity as linear actuators. However, it is understood that any other linear or rotary actuators as well as any other linkages or gear between the wheelsets and the bogie frame can be provided. A number of possible examples of this can be found, for example, in the initially cited DE 101 37 443 A1. Furthermore, the actuators 109, 110 can be based on any active principle. Thus, hydromechanical, electromechanical action principles or any combinations thereof can be provided.
- control device 1 13 which is connected to the respective actuator 109, 1 10 and controls each correspondingly.
- different variants of the control according to the invention can be followed, which are described below by way of example. All of these variants have in common that in a first frequency range, an adjustment of the turning angle of the respective wheelset 105, 106 in response to the current curvature of the track and in a second frequency range, a superimposed setting of the turning angle of the respective wheelset 105, 106 is such that is counteracted by track position disturbances or by a sinusoidal motion caused transverse movements.
- a sheet travel control takes place in the first frequency range, while in the second frequency range a superimposed stability control takes place.
- the first frequency range is from 0 to 0.5 Hz, while the second frequency range is 4 to 8 Hz. This makes it possible to optimize the handling of the bogie and thus the rail vehicle both in the track bend and at high speeds in the straight track.
- the sheet travel control ie the setting of the turning angle of the first gear 105 in the first frequency range, by the control device 1 13 using a first desired turning angle ⁇ z i s , the one with a predetermined first correction factor K first multiplied first ideal target turning angle ⁇ z1s , that is, it holds that:
- the return turning moment M cxp1 of the first primary suspension 107 with the turning moment M Tx1 resulting from the wheel-rail pairing at the first gearset 105 is substantially in the Equilibrium is, as is the case with a passive bow-friendly chassis, ie:
- the first actuator 109 follows the outward movement of the first gearset 105 caused by the track curvature until, as in a passive bow-friendly chassis, the first gearset 105 is set at least approximately at right angles ,
- a new first ideal target turning angle ⁇ z1s ⁇ is intermittently or continuously given when turning out the first set of wheels 105 from a current position, in which the load freedom to be achieved is expected in view of the current load on the first actuator 109.
- the first ideal target turning angle ⁇ z1s intermittently or continuously, can be tracked for the boring movement and thus for the current track curvature.
- a reference variable for the tracking of the first ideal-desired turning angle ⁇ z i s ⁇ any size can be used, which is representative of the load freedom of the actuator.
- this variable is preferably selected as a function of the measuring principle with which the actuator load is determined.
- the current turning angle of the first set of wheels 105 and a variable representative of the current load on the first actuator 109 are preferred.
- Torque value, a pressure value, a current value, etc. via suitable sensors. It is then a corresponding new first ideal target turning angle ⁇ z1s , given if the load on the first actuator 109 deviates from zero. This can be done intermittently or continuously, it being possible to ensure, for example, via temporal integration of the variable representative of the load on the actuator 109 that only the load situation on the actuator 109 in the first frequency range is detected.
- the first setpoint turning angle ⁇ z1s used in the control can be deliberately detuned with respect to the first ideal set turning angle ⁇ z1s ⁇ .
- an overcompensation or undercompensation can be achieved, which, however, is associated with an expenditure of energy and results in M Ak t ⁇ 0.
- Route conditions can be varied. This allows any wear distributions can be achieved.
- the first wheelset 105 of the moving rail vehicle 101 experiences a certain lateral deviation of its center from the middle track position when driving over a lateral defect of the track, and as a result a lateral acceleration, which leads to a transverse speed of the first wheel 105 to the track.
- a corresponding profile combination of wheels and rails would be weak by the speed coupling of the two rigidly mounted on the axle shaft connecting them
- the instantaneous transverse speed of the first gearset 105 and the instantaneous travel speed of the rail vehicle 101 are determined. From the determined instantaneous lateral velocity of the first gearset 105 and the instantaneous vehicle speed of the rail vehicle, a second ideal target turning angle ⁇ z2s ⁇ is calculated for the second frequency range as the second ideal target value.
- the resulting lateral speed of the first wheel set 105 of the wheel unit can be regulated to zero hereby.
- the instantaneous transverse speed of the wheelset v y is detected by suitable sensors, which z. B. are attached to the axle bearings. These may be, for example, laterally acting acceleration sensors whose signals are time-integrated.
- the current vehicle speed v of the rail vehicle is fed into the control, which is recorded for example from the parent train control system or from well-known speed measuring devices.
- This calculated value of the ideal target turning angle ⁇ z2s ⁇ is supplied to the control device 113 of the sufficiently high dynamics with a sufficiently low phase shift capable first actuator 109.
- the second wheel 106 of the bogie 103 is also controlled by this stability control method to keep him despite longitudinally soft articulation laterally and in terms of its turning motion at rest.
- any, possibly time-dependent detuning of the second setpoint used over the second ideal setpoint can be achieved over the second correction factor (K 2 ), as described above for the arc radial adjustment, any, possibly time-dependent detuning of the second setpoint used over the second ideal setpoint. So it is also possible for the stability control, detune the scheme against the locally very wear- prone ideal control with the second ideal target turning angle ⁇ z2s ⁇ targeted without having to give up the benefits of ideal control. It has been shown that a better distribution of wear on the wheel treads can be achieved even with small, defined deviations from the ideal control with still good sheet travel behavior and good stabilization in the straight track, resulting in a much more favorable wear pattern and thus longer life.
- the correction factor K 2 can, of course, also be varied as a function of the current or expected driving state (speed, etc.) or the current or expected route state (routes profi I, etc.). This allows any wear distributions can be achieved.
- the controller 1 13 z For example, in the case of bad track quality, it may be set to be “sharper” in order to react more strongly or, for example, to be “softer” at a low driving speed, in order to prevent excessive loading of the respective actuator 109, 110.
- the stability control method has the advantage of great simplicity, since no time history has to be recorded, but at any time only the instantaneous state of motion of the first gear set 105 is considered.
- each set of wheels 105, 106 can be controlled independently of the other wheel set of the same chassis 103 or vehicle 101. Reactions to disturbances in the track and possible instabilities are eliminated immediately on wheelset 105, 106 by the control.
- the wheelset 105, 106 remains in spite of longitudinally soft Radsatz Installation with respect to its movements in the transverse direction and about its vertical axis at rest, d. H. stable. Therefore, no damping means against rotational movements about the vertical axis between wheels 105, 106 and chassis 103 or between the chassis 103 and the car body 102 and wheel 105, 106 and 102 car body required. Since, instead of damping instability, such can not occur at all, the body 102 also behaves much quieter than conventional solutions.
- a third desired turning angle ⁇ z3s which corresponds to a third ideal target turning angle ⁇ z3s ⁇ multiplied by a predefinable third correction factor K 3 .
- the control device 113 calculates the third ideal target turning angle ⁇ z3s ⁇ preferably from the turning moment M Tx i on the first set of wheels 105 resulting from the current curvature of the track from the wheel-rail pairing, a dependence of the turning moment M Cxp2 on the bogie 103 the second primary suspension 108 of the turning angle ⁇ z3 of the second set of wheels 106 and a predetermined for the bogie 103 dependence of the turning moment M Ak t 2 of the second actuator 1 10 of the turning angle ⁇ z3 of the second gear 106.
- Such a dependence of the turning moment M Ak t 2 of the second actuator 1 10 of the turning angle ⁇ z3 of the second set of wheels 106 may be predetermined in any manner, for example, by a predetermined equation, a characteristic or a map, etc., or the advance for the bogie 103 and the vehicle 101 was determined.
- the third correction factor K 3 - in the same way as described above in connection with the first correction factor K 1 - again any, possibly time, Fahrsituations- and / or distance situation-dependent detuning of the used third desired turning angle ⁇ z3s against the third ideal target turning angle ⁇ z3s .
- the third correction factor K 3 similar to the first correction factor K 1 at least temporarily be selected unequal to one and / or at least temporarily equal to one and / or be varied according to a predeterminable course.
- the control device 1 13 proceeds here as described above in connection with the first control variant , ie using a second desired turning angle ⁇ Z2S , which corresponds to a second ideal target turning angle ⁇ z2s ⁇ multiplied by a predefinable second correction factor K 2 . It should therefore be made at this point only to the above statements.
- the sheet travel control ie the setting of the turning angle of the first gear 105 in the first frequency range, by the control device 1 13 using a first desired turning angle ⁇ z i s , which in turn one with a predetermined first correction factor K first multiplied first ideal target turning angle ⁇ z1s ⁇ corresponds, ie it also applies here:
- the second wheelset 106 is also controlled by this method.
- the setting of the turning angle of the second set of wheels 106 in the first frequency range therefore takes place using a third setpoint turning angle ⁇ Z 3 S , which corresponds to a third ideal set turning angle ⁇ z3s ⁇ multiplied by a predefinable third correction factor K 3 .
- the curvature of the track corresponding tracking of the first ideal target turning angle ⁇ z is ⁇ or the third ideal target turning angle ⁇ z3s ⁇ can be done in any suitable manner.
- the current turning angle ⁇ z1 of the first set of wheels 105 or the current turning angle ⁇ z3 of the second set of wheels 106 and a variable representative of the load on the respective actuator 109, 110 are preferred Current value, etc.).
- any desired, possibly time-, driving situation and / or distance situation-dependent detuning of the first or third setpoint value used relative to the first or third ideal setpoint value can again be determined via the first correction factor K 1 or the third correction factor K 3 be achieved. So the first one Correction factor K 1 or the third correction factor K 3 are selected at least temporarily unequal to one and / or at least temporarily selected equal to one and / or varied according to a predeterminable course.
- the control device 1 13 proceeds here as described above in connection with the first control variant , ie using a second desired turning angle ⁇ Z2S , which corresponds to a second ideal target turning angle ⁇ z2s ⁇ multiplied by a predefinable second correction factor K 2 . It should therefore be made at this point only to the above statements.
- the setting of the turning angle of the second set of wheels 106 takes place in the first frequency range, however, using a third desired turning angle ⁇ Z 3 S , which corresponds to a third ideal set turning angle ⁇ z3s ⁇ multiplied by a predefinable third correction factor K 3 .
- the turning angle between the bogie frame 104 and the body 102 is determined via a sensor 1 15 connected to the control device 113.
- any desired, possibly time-, driving situation and / or distance situation-dependent detuning of the first or third setpoint value used relative to the first or third ideal setpoint value can again be determined via the first correction factor K 1 or the third correction factor K 3 be achieved.
- the first correction factor K 1 or the third correction factor K 3 at least temporarily be selected unequal to one and / or at least temporarily equal to one and / or be varied according to a predeterminable course.
- the control device 1 13 proceeds here as described above in connection with the first control variant , ie using a second desired turning angle ⁇ Z2S , which corresponds to a second ideal target turning angle ⁇ z2s ⁇ multiplied by a predefinable second correction factor K 2 . It should therefore be made at this point only to the above statements.

- the control device 1 13 proceeds here as described above in connection with the first control variant , ie using a second desired turning angle ⁇ Z2S , which corresponds to a second ideal target turning angle ⁇ z2s ⁇ multiplied by a predefinable second correction factor K 2 . It should therefore be made at this point only to the above statements. It is understood that in all the control variants described above, the drive and braking torques influence the action of the sheet travel control, in particular in the case of the asymmetrical solution illustrated in FIG. They generate a force on the respective actuator rod, which results in a turning out of the respective wheelset - equivalent to a bow travel. However, the drive and braking torques can be superimposed on the control loop and thus compensated by suitable measurement (eg bar force measurement on the non-actuator side) or by transmission from the train control system.
- suitable measurement eg bar force measurement on the non-actuator side
