Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stabilizer bar fixing structure of a vehicle suspension device, comprising: a bolt passing through an end fixing hole of a stabilizer bar and a fixing hole of a lower suspension arm, a nut fastened to the bolt, and a number interposed between the bolt and the nut. In the stabilizer bar fixing structure of a suspension device for a vehicle including two retainers, a rubber bush and a spacer, a limiting jaw restricting the fastening of the nut is formed at the nut final fastening position of the bolt, so that the nut can be easily fastened. . Therefore, it is possible to secure the stabilizer bar by fastening the nut to the limiting jaw of the bolt without managing the tightening force of the nut separately. In the present invention, since the nut is always fastened with a constant fastening force, it is expected to exhibit sufficient function of the stabilizer bar, and the assembly and productivity of fixing the stabilizer bar can be improved.

Description

Stabilizer bar fixing structure for vehicle suspension

The present invention relates to a suspension of an automobile, and more particularly to a stabilizer bar fixing structure of a vehicle suspension.

In the vehicle suspension system, the stabilizer bar is provided to pass through the left and right lower suspension arms and the frame, and does not work when the left and right wheels operate vertically at the same time, but the left and right wheels are twisted when the left and right wheels operate vertically. The spring force reduces the inclination of the vehicle body and serves to maintain the vehicle body balance.

Here, whether or not the above described stabilizer bar is fully functional is due to fixing to the left and right lower suspension arms of the stabilizer bar. That is, the stabilizer bar is fixed to the lower suspension arm by a bolt and nut fastening structure, where the action is different depending on the degree of fastening force of the nut. Therefore, it is required to manage the nut clamping force when assembling the stabilizer bar.

In Figure 1 a fixed structure of a general stabilizer bar is shown in an exploded perspective view. Its assembled state is shown in cross section in FIG.

In the figure, reference numeral 1 is a stabilizer bar, 2 is a lower suspension arm, 3 is a fixing bolt and 4 is a nut.

As shown, the stabilizer bar 1 is fixed to the lower suspension arm 2 by means of a bolt 3 and a nut 4.

Between the bolt 3 and the nut 4, several retainers 5, a rubber bush 6, and a spacer 7 are interposed.

That is, the retainer 5, the rubber bush 6, and the spacer 7 are sequentially inserted into the bolt 3, and then the bolts 3 are secured to the lower suspension arm 2 and the stabilizer bar 1. It is inserted and fastened and fixed with the nut 4, and the degree of fastening thereof is tightened while the nut is fastened and managed with the length of the remaining bolt (the length indicated by L in FIG. 2).

However, in the conventional stabilizer bar fixing structure as described above, it is difficult to manage the nut fastening force affecting the function of the stabilizer bar by managing the tightening force of the nut by fastening the nut to the bolt and measuring the length of the remaining bolt. In addition, assembling takes a lot of time, causing assembly and productivity degradation.

The present invention has been made in view of the above-mentioned point by setting the exact tightening position of the nut (the length corresponding to the nut fastening force that the stabilizer bar can perform optimal function) to the bolt in advance to manage the tightening force of the nut separately. It is an object of the present invention to provide a stabilizer bar fixing structure of a vehicle suspension system, which enables the nut to be easily tightened without need.

The object of the present invention as described above is a bolt passing through an end fixing hole of a stabilizer bar and a fixing hole of a lower suspension arm, a nut fastened to the bolt, several retainers, a rubber bush interposed between the bolt and the nut, and In the stabilizer bar fixing structure of a suspension device for a vehicle including a spacer, a suspension jaw restricting the fastening of the nut is formed at the nut final fastening position of the bolt, the vehicle suspension device characterized in that the nut can be easily fastened By providing a stabilizer bar fixing structure.

The stabilizer bar fixing structure of the suspension device for a vehicle according to the present invention has a limiting jaw limiting the fastening of the nut at the nut final fastening position of the bolt, so that the nut does not need to separately manage the tightening force of the nut. The stabilizer bar can be fixed by tightening up to. Therefore, since the nut is always fastened with a constant fastening force, the stabilizer bar can be fully exhibited and the assembly and the productivity of the stabilizer bar can be improved.

EXAMPLE

Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

3 is a cross-sectional view illustrating a fixing structure of a stabilizer bar of a vehicle suspension apparatus according to the present invention. As shown in the drawing, the basic structure of the present invention is made as in the conventional case.

That is, according to the present invention, the bolt 3 inserted into the fixing hole of the stabilizer bar 1 and the fixing hole of the lower suspension arm 2, the nut 4 fastened to the bolt 3, and these bolts ( 3) and several retainers 5, a rubber bush 6, and a spacer 7 interposed between the nut 4 and the bolt 3 to fasten the fastening position of the nut 4 fastened thereto. It has a limiting jaw portion 3a for limiting.

Here, the limiting jaw portion 3a of the bolt is formed at the position where the nut is finally fastened, that is, the length (length indicated by L1 in FIG. 3) corresponding to the fastening force of the nut for which the stabilizer can exert the optimal function of the bar. It is.

Therefore, in fastening the nut 4, it is necessary to fasten to the limiting jaw of the bolt without separately managing the fastening force of the nut. This means that the nut can be easily tightened as compared with the conventional nut tightening while checking the remaining bolt length from time to time to manage the proper tightening force of the nut to the bolt. Productivity can be improved.

As described above, the stabilizer bar fixing structure of the suspension device for a vehicle according to the present invention has a limiting jaw limiting the fastening of the nut at the nut final fastening position of the bolt, so that the nut is not required to be managed separately. The stabilizer bar can be fixed by fastening to the limiting jaw of the bolt. Therefore, since the nut is always fastened with a constant fastening force, the stabilizer bar can be fully exhibited and the assembly and the productivity of the stabilizer bar can be improved.

In the above, one embodiment for carrying out the stabilizer bar fixing structure of the vehicle suspension apparatus according to the present invention has been shown and described, but the present invention is not limited to the above-described embodiment, but the present invention as claimed in the following claims Various changes can be made by those skilled in the art without departing from the gist of the present invention.
