Definitions

  • the invention relates to a device for avoiding undesirable movements in the construction of motor vehicles.
  • the standard here are springs arranged between the wheel axle and the body of the motor vehicle, which oppose the movement of the wheels in relation to the body with a growing force. Faster vibrations are eliminated or at least greatly reduced by dampers coupled to the springs.
  • DEOS 3738284 describes an active chassis control for motor vehicles, which is based on known level controls, and a first active actuator for which, depending on the relative spring deflection, is applied
  • Level control system and a second active actuator in the form of an active or a semi-active damper between the wheel suspension and vehicle body has a very high energy requirement.
  • EPPS 444278 to connect a spring element with an actuator in series to regulate the movement of a vehicle body, this series connection also having a supporting spring connected in parallel between the vehicle body and the wheel axle.
  • the invention is therefore based on a device of the type resulting from the preamble of claim 1.
  • the object of the invention is to provide a simply constructed and effective device by means of which a fast active regulation of the movements of the vehicle body is possible to increase the vehicle stability.
  • the object of the invention is also to provide a shock absorber which is particularly suitable for simple and quick regulation.
  • the invention therefore consists in using an electromechanical actuator for active control of the movements of the vehicle body, which can carry out the necessary mechanical adjustment movements very simply and quickly, such an actuator being comparatively inexpensive.
  • a hydraulic actuator with complex lines, accumulators and pumps can thus be dispensed with.
  • the invention creates a dynamically active chassis control in a surprisingly simple manner, which without hydraulic pressure supply needs. Based on the invention can also be achieved that the energy consumption is minimized and comfort is increased.
  • an electromechanical drive forms an active spring damper system, which is with its drive and, as additional units to be accommodated in the vehicle, only requires an electrical power supply and an electrical control.
  • the hydraulically independent damper can be retained.
  • a particularly simple structure for the actuator results from the combination of features listed in claim 2.
  • a comparatively inexpensive electric motor is inserted into the area of the body, which is supported on a wheel axle by the device according to the invention.
  • This electric motor drives a threaded spindle, on the thread of which a non-rotatably arranged and axially movable threaded screw is seated. If the spindle rotates, the screw moves up and down, changing the height of the body.
  • the motor and the spindle driven by it react very quickly to corresponding actuation signals, so that the arrangement described is very well suited for dynamic control of the movements of the vehicle body.
  • the vehicle has a hydraulic unit, for example for power steering, it may be advisable to choose a hydraulic drive to drive the actuator.
  • Relief spring which is preferably set such that it keeps the thread largely free of contact forces due to the structure of the vehicle with its windings not standing on the block, it is possible that only the dynamic movements of the structure need be effected by the actuator. The thread is largely spared from the support forces of the structure. However, it is necessary that the actuator must work against the force of the relief spring in the case of downward movements of the body.
  • the spring should be set so that the force to be exerted by the motor is the same in both directions.
  • Active chassis control systems are intended to reduce or completely compensate pitch and roll movements of the vehicle body by means of control interventions. To do this, each of the four actuators must be able to raise its vehicle corner. The lifting work required for this is the integral of (adjustment force x adjustment path). If the actuator is relieved of the purely static force component, only a fraction of the energy has to be used during control interventions. Therefore, as shown in Figure 2, it is proposed according to claim 3 to use parallel to the actuators relief springs (6) which are statically matched so that the actuators (1) are relieved when the vehicle is at rest.
  • gas springs offer compared to steel springs a higher suspension comfort.
  • static deflection for example caused by an increase in weight as a result of the load, can be compensated for by supplying air.
  • the special advantage of gas springs steel springs is that the own frequency of the FederMasseSyste s is almost independent of the payload.
  • the system shown in FIG. 3 thus has gas springs (7) which offer greater suspension comfort than steel springs.
  • a static deflection for example caused by an increase in weight as a result of an additional load, can be compensated for by the supply of air (level control).
  • the special advantage of gas springs over steel springs is that the natural frequency of the spring-mass system is almost independent of the payload.
  • the upper end of the gas springs (7) For example, as a plate (9) designed to be adjustable by an actuator (1), as shown in FIG. 4. It is advantageous to use an electromechanical drive (1), but if a hydraulic unit, for example for a power steering, is already present in the vehicle, the hydraulic drive may also be an inexpensive variant. In any case, it is advantageous to use the actuator relief spring (6 or 8) to reduce energy consumption. All advantages are combined in a system that uses both gas suspension springs (7) and gas actuator relief springs (8) (FIG. 4), with both gas springs either being able to supply or discharge air independently of one another or one of these springs, the other gas spring can be connected to this via an electrically controllable pneumatic valve.
  • the electromechanical drive (1) can preferably be accommodated within the actuator relief gas spring 8.
  • the struts according to the invention are equipped with displacement sensors (10). Furthermore, sensors can also be provided for the actuator paths. Both sensor systems can be combined in the spring strut to form a sensor unit. In addition, the pneumatic pressures in the gas springs can also be sensed to determine the exact system status. In an advantageous development of the invention, the use of the features listed in claims 9 and 10 is therefore recommended
  • the system presented here combines the advantages of the sophisticated pneumatic system for active chassis level control and the electromechanical actuators optimized in terms of efficiency, design and power density to form a fully active chassis control system with minimal energy consumption. Electrical energy is only used in a medium dynamic range.
  • Very fast compression movements are absorbed by the conventional hydraulic damper, slow movements by a pneumatic level control system.
  • the middle area which is covered by the electromechanical actuators, primarily concerns the control of roll, pitch and lifting movements of the vehicle, such as occur when cornering, accelerating and braking and when driving over bumps.
  • Fig. 1 a device provided with a steel spring supporting spring device or the strut belonging to this device
  • Fig. 2 shows the device or strut of FIG. 1, in which a relief spring was also inserted
  • Fig. 3 shows a device or strut corresponding to Fig. 1, in which the steel spring has been replaced by a gas spring and
  • Fig. 4 shows the embodiment of FIG. 2, in which both the suspension spring and the relief spring are formed by gas springs.
  • Fig. 1 shows a support 12 on which the structure of the vehicle in Fig. 1 can be directed downward.
  • the Pad 12 sits on rubber buffer 13 on a motor housing 14 which receives an electric motor 15 as electromechanical drive 1.
  • the motor is anchored with its poles 16 in the motor housing 14.
  • the rotor of the motor is optionally connected in one piece to a threaded spindle 17, on the ball thread 18 of which a threaded screw 19 is non-rotatably but axially movable. If the threaded spindle 17 is rotated in one of two directions by the electric motor, the threaded screw 19 moves up or down. Balls are inserted between the thread of the threaded screw and the threaded spindle, which together produce a ball gear.
  • the threaded screw 19 moves upward and thus raises the support 12.
  • the support is lowered.
  • the threaded screw 19 is held in a connecting sleeve 20, the upper edge of which forms a plate 9 on which a suspension spring 21 is supported with its upper end in FIG. 1.
  • the electromechanical drive 1 and the suspension spring 21 are thus connected in series.
  • the suspension spring 21 is seated on a housing 22 of a damper 23, wherein the housing 22 of the damper can consist of several parts.
  • the lower end 24 of the damper 23 is at least indirectly connected to a wheel axle, which is not shown in FIG. 1.
  • the damper 23 has, as usual, a piston 25 which is guided sealingly on the inner surface of the housing 22. As usual, the damper has the task of compensating for rapid vibrations of the wheel compared to the structure of the vehicle.
  • the piston rod 26 of the damper 23 is connected to the connecting sleeve 20 so that the vibrations of the suspension spring 21 against the connecting sleeve 20 are damped by the damper 23.
  • the motor housing 14 and the housing 22 of the damper 23 are provided with a first diaphragm 27 and a second diaphragm 28 which interlock in a telescopic manner.
  • a sensor In order to be able to regulate the movements of the structure and thus the support 12, a sensor must be inserted which can measure such movements.
  • a first sensor 30 is therefore inserted at the bottom of the connecting sleeve 20 and is able to measure the movement of the connecting sleeve 20 and thus of the threaded screw 19 relative to the support 12.
  • a pin 29 anchored relative to the support 12, which transmits the movement of the support 12 relative to the connecting sleeve 20. This movement can be measured by the first sensor 30.
  • the first sensor or further sensors can be attached to other suitable locations on the device.
  • FIG. 3 is largely the same as that of FIG. 1, only that the suspension spring 21 has been replaced by a gas spring 7, which can also be used to regulate the level, that is to say the control of the height of the support 12 relative to the road.
  • a gas spring 7 which can also be used to regulate the level, that is to say the control of the height of the support 12 relative to the road.
  • both the suspension spring 21 and the relief spring 6 have been replaced by a gas spring 7 and 21, respectively.
  • the two gas springs can be controlled and fed by a common source so that the suspension spring can be adjusted to a certain extent.
  • the suspension spring 7 can also remain reversed by being filled up once and remaining in this state later.
  • the gas spring 7 may further serve to change the height of the support 12 in greater extent to ', to thereby control the level that is the distance between the support 12 and the road surface is obtained.
  • the smaller vibrations of the support 12 can at least be compensated for by the second gas spring 8.
  • the gas springs can be made in one piece via a split bellows. However, it is also possible to fill the upper bellows belonging to the relief spring 6 once with gas and to actuate the gas spring 7 by means of a corresponding gas source for regulating the level.
