- the actuators 106, 107 are modular, so that different performance and functional requirements can be realized with little effort. In addition, extensive diagnostic functions are provided, which can detect all major types of failure of the actuators 106, 107 in good time and a repair or replacement of the affected
- At least one further actuator unit is provided, as indicated in FIG. 4 by the dashed contour 15.
- This further actuator unit 1 15 is supplied via a control unit 1 15.1 of the first actuator 106 from the power source 06.1 with the hydraulic fluid.
- This further actuator unit does not necessarily have to be arranged in close spatial proximity to the first and second actuator units 106.3, 06.4. Rather, this may also be a remote actuator unit. This makes it possible in an advantageous manner, with only one energy source 106.1 diverse Stell tasks (of any kind) to realize in the vehicle.
- the further actuator unit 1 15 for generating actuating movements for a level control of the vehicle 101 and / or for a brake of the vehicle 101 and / or for an active damper of the vehicle 101 and / or for an additional device for (quasi-static and / or dynamic) influencing the deflection of the car body 102 in the vehicle transverse direction formed.
- the actuator units 106.3, 106.4 of the first actuator 106 both operate in the lower first and third frequency ranges while the
- Actuator units 107.3, 107.4 of the second actuator 107 both operate in the higher second and fourth frequency ranges. It is understood, however, that in others
- actuator units 106.3, 106.4 of the first actuator 106 operate in different frequency ranges.
- the second actuator unit 106.4 operates in the higher fourth frequency range.
- the fourth actuator unit 07.4 will then operate in the lower second frequency range.
- the actuator units 106.3, 106.4 of the first actuator 106 act on the vehicle body 102 in the first or second frequency range, for example, both being designed as linear actuators (or both as a pivot drive) can.
- the control module 1 12 is then preferably designed to control the remaining actuator 106.3 and 106 4 such that they malfunction of the failed actuator unit 106.3 or 106.4 at least partially in case of failure of one of the two actuator units 106.3, 106 takes over.
- Comparable can apply in this variant for the second actuator 107, whose (then, for example, both trained as a rotary actuator or linear actuators)
- Actuator 107.3, 107.4 act on the wheelsets 103.1 and 103.2 in the third and fourth frequency range.
- actuator in further variants of the actuator according to the invention two or more individual actuator units of any kind (linear, rotary, etc.) and effective direction can be used. Likewise, all built-actuator units can be controlled independently of each other via their own valve units, the frequencies, amplitudes and force levels of the positioning movements can be arbitrarily selected and combined.
- Vehicle longitudinal direction is integrated within the chassis frame 103.4.
