Principle of work of the present utility model as described in Figure 4.
In the time that automobile left steering travels, because centnifugal force spring carried mass occurs to be taken turns to the effect of the transfer of foreign steamer by interior, automobile is rolled to the right.Automobile ECU control system provides needed target current by analyzing vehicle roll angle and lateral acceleration to motor; Simultaneously according to steering wheel angle speed and these two parameters of the speed of a motor vehicle of feeding back to
Constantly revise the electric current of motor, make worm screw rotation according to correcting current and target current sum.In the time that driven by motor worm screw is rotated, worm gear drive first is stablized half bar and is produced the hand of rotation as shown in Fig. 2 front view arrow.The second hand of rotation of stablizing half bar 9 of and sun gear 7 spline joints known by the relation between the gear of Fig. 2 is as shown in the arrow of Fig. 2 front view, the automobile now travelling for left steering produces anti-bank moment, the size of anti-bank moment is according to the size of motor outgoing current, by corresponding gear transmission, make torsion bar produce different moments of torsion and control, when reducing the angle of roll of automobile to realize, guarantee the stability of vehicle.Turn right or travel in the time that the road surface generation larger side that jolts inclines when automobile, its principle of work is identical with left-hand rotation, no longer repeats at this.
ECU is according to the signal of steering wheel angle sensor and angle of roll sensor, judge automobile whether straight-line travelling on compared with flat road surface.In the time that automobile straight-line travelling is on compared with flat road surface, ECU controls magnetic clutch 12, make it separate, now motor tickover, prevent motor because of frequent starting affect service life and guarantee respond sensitieness.Now, worm screw 11 shuts down, and due to the self-locking action between worm and gear, in the time that automobile one side runs into less jolting, the moment of torsion of stablizing half bar generation of this side does not affect opposite side, thereby has improved the ride comfort of running car.In the time that system breaks down, ECU controls magnetic clutch 12, and worm screw is shut down, worm and gear self-locking, and its principle of work and straight-line travelling are similar, no longer repeat.
