Description

Stabilizer bar installation structure for car {MOUNTING STRUCTURE OF STABILIZER BAR FOR AUTOMOBILE}

The present invention is directed to a stabilizer bar mounting structure applied to automotive suspensions to reduce rolling.

In general, independent suspensions applied to automobiles are classified into McPherson type, double wishbone type, semi-trailing arm type, and the like. The above-mentioned independent suspensions reduce rolling by each lifting and lowering of each wheel. Stabilizer bar is installed for this purpose.

This is a cross member 50 is fixed to the vehicle body (not shown) as shown in Figure 3, and one end is coupled to the cross member 50 so as to be rotatable movement and the wheel (not shown) is coupled to the other end Both ends of the arm 51 and the cross member 50 are fixed to the cross section by the brackets 52 and the link members 54 are interposed between the mounting brackets 53 of the arms 51 on both sides. The stabilizer bar 55 is connected.

That is, when the arm 51 moves up and down along the wheel, the stabilizer bar 55 connected to the link member 54 is twisted in the A direction to reduce rolling of the vehicle.

Here, as shown in Fig. 4, the stabilizer bar 55 acts not only on the stress in the torsional direction A but also on the force P for generating the vehicle width direction deformation. The mounting bracket 53 installed in the) acts as a force that is deformed in the vehicle width direction, thereby reducing rolling.

However, as described above, when the force P for deforming the mounting bracket in the vehicle width direction acts excessively to permanently deform the mounting bracket and to act differently on both wheels, the deformation amount of both mounting brackets is different. The position of one stabilizer bar is deflected to one side, which causes a problem that the rolling damping effect is lowered.

In addition, when the stabilizing bar is deflected from the center of the vehicle to one side as the amount of deformation of the mounting brackets of both arms is different, the torsion stress applied to the stabilizer bar acts differently on both wheels, thereby causing excessive force to be applied. There is a problem in that noise and breakage occur in the wheel and the stabilizer bar and the arm connection part.

Accordingly, an object of the present invention is to solve the above problems, the stabilizer bar is deflected to one side according to the force acting in the width direction of the stabilizer bar, thereby reducing the rolling effect and stabilizer bar and arm connection portion, etc. To provide a stabilizer bar mounting structure for cars that can prevent damage.

In order to achieve the above object, the present invention supports a stabilizer bar arranged in a vehicle width direction to a vehicle body, and in the vehicle stabilizer bar installation structure in which an intermediate portion is fixed to the bracket so as to rotate in the vehicle width direction. A slider coupled to both ends of a stabilizer bar, the slider being connected by slide means so that only the stress in the torsional direction is applied to the stabilizer bar and slideable through the stabilizer bar by the stress applied in the vehicle width direction; One end is coupled to the hinge to enable the rotational movement as well as the other end is coupled to the mounting bracket of the arm is characterized in that it comprises a link configured to twist the stabilizer bar during the lifting and rotating movement of the arm.

1 and 2 are a partially enlarged perspective view showing a structure for installing a stabilizer bar for automobiles according to the present invention and a plan view of FIG. 1, which are coupled to both ends of the stabilizer bar 55 to stabilize only a stress in a torsional direction. A slider 1 connected to the slide means so as to slide on the stabilizer bar 55 by a stress applied to the bar 55 and applied in the vehicle width direction, and rotated in the vehicle width direction to the slider 1. One end is coupled to the hinge hole (2) and the bolt (3) to enable movement, and the other end is coupled to the mounting bracket (53) of the arm (51) to move the stabilizer bar (55) during the lifting and lowering movement of the arm (51). It consists of a link 4 configured to be twistable.

The slide means has a polygonal portion 5 formed at both ends of the stabilizer bar 55 and a polygonal portion formed at one end of the slider 1 so as to be fitted to the polygonal portion 5 and slidable in the vehicle width direction. The fixed hole 7 is screwed to both ends of the moving hole 6 and the stabilizer bar 55 mentioned above, and the slider 1 is prevented from coming off.

Here, the length D 'of the polygonal portion 5 is formed longer than the width D of the slider 1, and the slider 1 is configured to be slidable in a predetermined stroke, and the slider 1 and the link ( 4) is eccentric with the center C of the stabilizer bar 55, it is possible to twist the stabilizer bar 55.

Referring to the operation and effect of the present invention as described above, when the wheel is bound along the road surface while driving the vehicle, the arm 51 connected to the cross member 50 is rotated, the arm 51 is rotated In this case, the link 4 and the slider 1 connected to each other rotate about the center line C of the stabilizer bar 55.

That is, since the moving hole 6 of the slider 1 and the polygonal portion 5 of the stabilizer bar 55 are fitted to each other, the slider 1 and the stabilizer are rotated when the slider 1 is rotated in the A direction. When the riser bar 55 is twisted together, the stabilizer bar 55 is moved while the link 4 and the slider 1 rotate in the A direction about the C line which is the centerline of the stabilizer bar 55. Will twist.

When the stabilizer bar 55 is twisted, rolling is reduced by the rigidity of the stabilizer bar 55.

Here, when P, the force in the vehicle width direction, is applied to the link 4 and the slider 1 during the rotational movement of the arm 51, the force P substantially moves the slider 1 in the vehicle width direction. .

In other words, the above-mentioned force P causes the slider 1 to slide on the polygonal portion 5 to mitigate or attenuate the force P.

Of course, when the force P in the vehicle width direction is applied to the link 4 and the slider 1, the link 4 is rotated by the hinge hole 2 and the bolt 3, the slider 1 is a polygonal portion (5) It is possible to move in the width direction while moving.

When the widthwise movement of the arm 51 can absorb the rotational movement of the link 4 and the widthwise direction of the slider 1, the mounting bracket 53 or the like of the arm 51 is deformed or damaged as in the prior art. It is possible to prevent the stabilizer bar 55 from being deflected and operated at the center of the vehicle.

As described above, the present invention absorbs the vehicle width direction force when the arm is bound by the hinge of the link and the slider and the movement of the slider, thereby preventing the stabilizer bar from being biased in the center of the vehicle and reducing the rolling effect. There is an advantage to it.
