Stabiliser is a kind of part that stabilizer rod (stabiliser bar) and wheel suspension are coupled together.Stabiliser belongs to the kinematic chain conventionally being formed by stabilizer rod, stabiliser, suspension and vehicle chassis.This element of stabiliser is responsible for the stress transfer being produced by stabilizer rod to wheel suspension, and vice versa, to produce the moment contrary with the roller moment of vehicle in vehicle chassis, thereby makes the lateral rigidity of vehicle larger.
In the time that vehicle enters bend, can produce centnifugal force, cause the outer inclination of vehicle body towards this bend, thereby produce roller moment.Meanwhile, the stabilizer rod that arrives wheel suspension by stabilizer attachment becomes curved, thereby produces the moment contrary with the roller moment of vehicle.By passive (length fixed type) stabiliser, this moment contrary with roller moment remains unchanged for passive system, but also has the initiatively stabiliser of variable-length formula so as to controlling this moment.
Fig. 1 schematically shows traditional components, and wherein stabilizer rod 101 is by passive accordingly, that is, length fixed type stabiliser 100 is attached to bumper 102.
US-A-2006/0113734 describes the example of variable-length formula stabiliser, and wherein motor is couple to the end of screw rod.But this configuration means that rotational force is transferred to member for stabiliser being connected or coupled to vehicle remainder or device (these members or install normally ball-and-socket type joint or its analogue), can cause like this and damage or wearing and tearing.On the other hand, the shock load that mechanism bears directly affects motor, so also can cause damage.
On the other hand, motor is directly connected to screw rod in the situation that not slowing down (reduction), the therefore relatively large motor of power demand, and this can mean, and energy consumption is quite high, volume is larger, weight is heavier and cost is higher.
Another aspect, supposes that the position of motor is at one end place of screw rod, and the length of assembly can be greater than Len req, because motor is connected with stabiliser itself.
On the one hand, in the unit moving, have intermediary element along screw rod again, this intermediary element absorbs the partial rotation of screw rod and makes to control more difficult.
US-A-5186486 describes another example of the variable-length formula stabiliser based on tooth bar and pinion gear mechanism, in principle, this stabiliser can be conducive to prevent that the rotational force of motor is transferred to coupler member with the form of torque, and these coupler member are for being couple to by stabiliser the vehicle that is arranged in stabiliser two ends.The tooth bar relevant to one of them coupler member can move in the enclosure relevant with another coupler member.But the tooth bar in the enclosure this layout of portion means and has certain mal-alignment risk between parts.In addition, although tooth bar and miniature gears system have advantage, it means that deceleration is limited, thereby may need the extra decelerating phase or use more powerful motor, and this shows again volume and weight and the cost aspect existent defect of mechanism.
DE-A-10 2,005 028 327 reflects a kind of fluid pressure type stabiliser completely.
KR-A-10-2009-0098039 reflects a kind of solution that substitutes, and does not wherein change the length of stabiliser, but the change strong point, that is, stabiliser itself is length fixed type stabiliser.What use is a kind of mechanism based on motor, and wherein worm screw acts in tooth bar and pinion assemblies.
