Abstract

PURPOSE: A fixing structure of a stabilizer bar for a vehicle is provided to suppress relative motion between the stabilizer bar and a bush and to suppress noise and wear of the bush, by integrally forming the stabilizer bar and the bush. CONSTITUTION: A fixing structure of a stabilizer bar(4) for a vehicle comprises the stabilizer bar; a bush(10) combined to the stabilizer bar; and a stabilizer bar bracket(50) fixing the bush to a vehicle body in a state of covering the bush. The bush is integrally combined to the stabilizer bar through vulcanization. A protrusion(10a) is formed to the upper part of the bush. An insertion support hole(50a) in which the protrusion is inserted and supported is bored in the stabilizer bar bracket.

Description

Stabilizer bar fixed structure for car}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stabilizer bar fixing structure for automobiles, and more particularly, to a stabilizer bar fixing structure for automobiles in which a bush is integrally formed on the stabilizer bar and a stopper is integrally formed on the bush.

In general, the stabilizer bar fixing structure assembly of a conventional vehicle is mounted on the cross member 2 so as to control the movement of the wheel, as shown in Figs. And a stabilizer bar (4) coupled to both ends of the pair of lower arms (1) by the stabilizer link (3), and the outer suspension is largely bent due to the load of the vehicle during the turning of the vehicle to prevent it from tilting to the side. And a stabilizer bar bracket (5) for fixing the stabilizer bar (4) to the cross member (2) by the fastening member (6), and wrapped by the stabilizer bar bracket (5), so that the load of the vehicle when the vehicle turns. When the stabilizer bar 4 rotates or shakes while the outer suspension is largely bent to the side, the stabilizer bar bracket 5 and the cross member 2 The through hole 11 to surround the stabilizer bar 4 to prevent the vibration is transmitted to the () and at the same time to prevent the noise generated while contacting the stabilizer bar bracket (5) and the cross member (2). Is formed of a bush 10 formed.

However, according to the conventional stabilizer bar fixing structure configured as described above, when the stabilizer bar 4 is rotated or shaken while the outer suspension is greatly bent due to the load of the vehicle when the vehicle is swiveled, the bush 10 may be rotated or shaken. There was a problem that excessive noise and abrasion were generated by surface friction and slipping with the inner surface of the formed through hole.

In addition, the stopper 20 shown in FIG. 4 is further installed in the stabilizer bar 4 in order to prevent the stabilizer bar 4 from being axially pushed out from the side when the lateral force is applied. The increase can reduce economics and performance.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and by fixing the stabilizer bar and the bush integrally, fixing the stabilizer bar of a vehicle having a structure capable of suppressing relative movement of the stabilizer bar and part time to suppress noise and bush wear. The purpose is to provide a structure.

In order to achieve the above object, a stabilizer bar fixing structure for a vehicle according to the present invention includes: a stabilizer bar; A bush coupled to the stabilizer bar; It includes a stabilizer bar bracket to secure the bushing to the car body,

The bush is vulcanized and integrally coupled to the stabilizer bar.

Through this configuration, it is possible to suppress the relative movement of the stabilizer bar and part time to suppress noise and bush wear as much as possible.

In the above-described configuration, a protrusion is formed on the upper portion of the bush, and an insertion support hole in which the protrusion is inserted and supported is installed in the stabilizer bar bracket to thereby suppress the bushing of the bush as much as possible.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail, the same reference numerals are attached to the same parts as in the prior art and detailed description thereof will be omitted.

5 is a cross-sectional view showing a stabilizer bar fixing structure according to a preferred embodiment of the present invention. As shown in FIG. 5, the stabilizer bar fixing structure of the present embodiment includes a stabilizer bar 4, a bush 10 coupled to the stabilizer bar 4, and a stabilizer bar fixed to the car body wrapped around the bush 10. The bracket 50 is comprised.

The bush 10 is a rubber having elasticity, and is manufactured by being vulcanized and integrally bonded to the stabilizer bar 4, thereby suppressing the relative movement between the stabilizer bar 4 and the bush 10.

The bush 10 has a stabilizer bar bracket 50 fixed to the vehicle body by the fastening member 6, thereby stably fixing the stabilizer bar 4 on the vehicle body.

Meanwhile, in order to suppress relative movement between the bush 10 and the stabilizer bar bracket 50, the rubber protrusion 10a is integrally formed in the bush 10, and the rubber protrusion 10a is formed in the stabilizer bar bracket 50. An insertion support hole 50a to be inserted and supported is drilled. This rubber protrusion 10a can be molded together at the time of vulcanization of the bush 10, thereby simplifying the manufacture.

Therefore, it is possible to prevent the stabilizer bar from being pushed by the lateral force without using an additional stopper.

The stabilizer bar fixing structure for a vehicle according to the present invention can be implemented without various modifications within the range allowed by the technical idea of the present invention without being limited to the above-described embodiment.

According to the stabilizer bar fixing structure for automobiles of the present invention examined as described above has the following effects.

First, the bush is vulcanized and integrally bonded to the stabilizer bar, thereby suppressing noise and bush wear caused by the relative movement of the stabilizer bar and the off-hours.

Second, a projection is formed on the upper portion of the bush, and the insertion support hole in which the projection is inserted and supported is installed in the stabilizer bar bracket, so that the projection can be formed together with the bush, which is easy to manufacture and does not use a separate stopper. As a result, cost and weight can be reduced, resulting in economic and performance improvement.
