Description

Stabiliser system for a vehicle
The invention is related to a stabiliser system for a vehicle, comprising a torsion coupling for connection to the unsprung masses on opposite sides of the vehicle, said torsion coupling comprising two torsion bar halves which are interconnected through a drive source for imparting a torque on the torsion bar halves.
A stabiliser system of this type is disclosed in DE-A-'l 9846275. This prior art stabiliser system comprises a single electric motor, the stator of which is connected to one of the torsion bar halves and the rotor of which is connected to the other torsion bar half. By energising the motor, opposite torques and rotations can be imparted onto the torsion bar halves for countering roll motions of the vehicle which occur upon cornering.
Although this prior art stabiliser system is fit for stabilising the vehicle in question with respect to roll motions, it cannot play a role in the case of pitch motions such as occur when braking or accelerating.
The object of the invention is therefore to provide a stabiliser system which is more versatile. This object is achieved in that the drive source comprises at least two motors which are each drivingly connected to a respective torsion bar half. Preferably, a clutch is provided which is transferable between a fixed position in which the coupling bar halves are coupled, and a free position in which the1 torsion bar halves are uncoupled.
The stabiliser system according to the invention can be applied both for countering roll and pitch motions, as well as combinations thereof. In this respect, the stabiliser system can in particular be applied to a vehicle having at least a wheel suspension with two braked wheels on either side and comprising at least one stabiliser system as described before. Said vehicle comprises sensors for sensing a braking action and/or a cornering action, as well as control means for controlling said system on the basis of data delivered by the sensors.
In the case of cornering, the vehicle with stabiliser system according to the invention is operated according to the following steps: detecting a cornering condition on the basis of data delivered by the sensors, selecting the free position of the clutch, energizing the electric motors so as to generate opposite torques on the torsion bar halves for countering the roll motion of the vehicle caused by the cornering condition.
In the case of braking or accelerating, the vehicle stabiliser system according to the invention is operated according to the following steps: detecting a braking or accelerating condition on the basis of data delivered by the sensors, selecting the fixed condition of the clutch, energizing the electric motors so as to generate torques with the same sign on the torsion bar halves for countering the pitch motion of the vehicle caused by the braking condition.
In case both roll and pitch motions occur, the stabiliser system can e.g. be operated by giving preference to countering the roll motion because the stability of the vehicle is best served by safely taking a corner. In this case the clutch will be engaged or disengaged.
In the stabiliser system according to the invention, each motor can be connected to a torsion bar half through a respective gear drive. Said clutch comprises clutch halves, each clutch half engaging a respective motor. Furthermore, each clutch half and a respective motor can engage each other through a respective gear drive. For instance, each motor can have a pinion gear, and the respective torsion bar half and clutch half each have a gear member, e.g. a gear wheel or gear wheel sector, said gear wheels or gear wheel sectors engaging the respective pinion gear on opposite sides.
The clutch can be carried out in several ways. For instance, the clutch can be a springloaded teeth clutch, the clutch halves each having radially oriented teeth, with the clutch disengaging using an electromagnetic clutch section against the springload.
Alternatively, the clutch halves are biassed towards the fixed position, an actuator can also be provided for displacing the clutch halves towards the free position against the biassing force. In the case of power failure, the clutch will be engaged and the stabiliser system will act as a normal torsion bar. In the case of an electromagnetic clutch, this actuator is an electromagnet. Alternatively, the actuator may be carried out as a screw actuator driven by e.g. an electromotor. Furthermore, a housing is provided, the stator of each motor being connected to said housing, and the torsion bar halves protruding from the housing at opposite ends thereof.
The invention will now be described further with reference to the embodiments of the stabiliser system shown in the figures.
Figure 1 shows a first embodiment of the stabiliser system. Figure 2 shows a second embodiment of the stabiliser system, including a housing.
Figure 3 shows a cross section according to III-III according to figure 1. The stabiliser system shown in figures 1 and 3 comprises two torsion bar halves
2, 3, which each have to be connected to the wheels on opposite sides of a vehicle, e.g. the front wheels or the back wheels. These torsion bar halves 2, 3 are interconnected to a drive source which in its entirety has been indicated by reference numeral 4. As shown in figure 3 this drive source comprises a teeth clutch 7, which has clutch house 10, 11 having radially oriented teeth 16. These clutch halves 10, 11 are biassed towards their coupling position by means of a spring 17. Through an actuator, e.g. an electromagnet, the clutch halves 10, 11 can be brought in their free position, against the biassing force of the spring 17.
The torsion bar halves 2, 3 are each coupled to a gear drive 8, 9, comprising each opposite gear wheels 14, 15. The gear wheels 14 are connected to the torsion bar halves, the gear wheels 15 to the clutch.
Furthermore, pinion gears 12, 13 have been provided which engage each a pair consisting of the gear wheels 14, 15. Said pinion gears 12, 13 are each connected to a respective motor 4, 5, preferably electric motors. The motor housings are stationary with respect to the housing 18 through which the torsion bar halves 2, 3 extend.
When the clutch 7 is in its fixed position, the stabiliser system acts in a normal way. That is, the torsion bar halves 2, 3 will move in unison through the combined action of the respective gear wheels 14, 15 and pinion gears 12, 13, which can rotate freely. In a cornering condition, the vehicle in question will carry out a roll motion, which can be actively counteracted by the stabiliser system. Upon detection of such cornering condition, e.g. by suitable sensors provided on the vehicle in question, the clutch 7 is brought in its free position. The motors 4, 5 are energized, so as to ensure that the torsion bar half 2, 3 which is at the side where the vehicle chassis is depressed as a result of the cornering action, is supplied with a torque and/or rotation which tries- to lift the vehicle body. The other torsion bar half 3, 2 is controlled in the opposite direction. As a result, the roll motion is actively counteracted. In case a braking or accelerating action is detected, the stabiliser system is controlled in such a way, that the clutch 7 is kept or brought into its fixed position, and the motors 4 and 5 are driven in opposite directions. As a result, both torsion bar halves 2, 3 obtain a torque and/or rotation in the same direction, so as to counteract the pitch motion which results from the braking action or accelerating action. The control signals are delivered through the clutch 7 and the motors 4, 5 through a control mechanism 20, which obtains data from vehicle sensors such as angle sensors, acceleration sensors 21 etc.
It will be clear that the forces required to counteract roll and/or pitch motion are considerable. Thus, the motors 4, 5 should be powerful enough to deliver the torques required. In this respect, a further improvement can be obtained by applying gear wheel sectors 19 as shown in the embodiment of figure 2, which increase the lever arm with respect to the torsion bar halves 2, 3. Besides electric motors also hydraulic motors can be considered.
The stabiliser system can be applied both for the front wheels and the rear wheels of automative vehicles. There wheels may be driven or non-driven: also application to towed vehicles is possible.
