Abstract

PROBLEM TO BE SOLVED: To eliminate any possibility of a positioning body from being deviated even if acting excessive lateral load thereon by caulking the metal positioning body having a clearance groove, on both sides of an insertion hole into which a material of a stabilizer are loosely fitted, wherein a flat part is loosely fitted, formed on a linear part and fixing it by caulking. SOLUTION: Clearance grooves 7 are formed in such positions corresponding to each other in its longitudinal direction in an approximately oval positioning body 6, which has an inside diameter a little larger than the outside diameter of a material (a) of a linear part 2 of a stabilizer 1, and the clearance grooves 7 are stacked on the wide-width flat part 4 so as to pass through a bent part 3 of the material (a), and moved to a prescribed position of the linear part so as to be positioned. After the positioning body 6 is locked in a prescribed position, it is pressurized by a press so as to shrink an insertion hole 8, and caulked to the linear part 2 so as to be fixed. The positioning body 6 can be firmly fixed to the linear part 2 of the stabilizer 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for lifting one wheel by elasticity when only one wheel is lifted by climbing onto a projection, and for preventing one wheel from falling into a concave portion. To prevent falling,
The present invention relates to a stabilizer for an automobile used to maintain a vehicle body in a horizontal posture in a left-right direction.

[0002]

2. Description of the Related Art A stabilizer for an automobile is composed of a straight portion causing a torsion and a curved portion causing a bend. The straight portion freely supports only rotation with respect to a vehicle body and moves in a longitudinal direction (lateral direction of the vehicle body). Therefore, it is necessary to fix the positioning body to the straight portion.

As such a positioning body, it is preferable to fix a ring that fits tightly to the straight portion by caulking or the like. However, a flat portion formed by flattening the tip of the curved portion is attached to the wheel side. Since a hole is formed, a ring having a large inner diameter must be used to pass the flat portion, and it is difficult to caulk the straight portion.

For this reason, conventionally, a hose band-shaped fitting has been fastened to a rubber ring, or an adhesive has been added between the ring and the stabilizer.

[0005]

However, such a fixing method does not always have sufficient fixing strength, and there is a problem that the positioning body may be displaced when an excessive lateral load is applied to the stabilizer.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the first aspect of the present invention, an insertion hole for loosely fitting into a material of a stabilizer and flat portions are loosely fitted on both sides of the insertion hole. Since the metal positioning body with the escape groove to be formed is fixed to the linear part by crimping, the positioning body having an insertion hole with an inner diameter slightly larger than the outer diameter of the stabilizer is fitted to the linear part and caulked. In addition, there is an effect that the positioning body can be firmly fixed to the linear portion of the stabilizer. In the invention of claim 2, since the positioning body is energized and heated and caulked in the invention of claim 1, adverse effects of heat on the stabilizer are caused. Therefore, there is an effect that the positioning body is heated without exerting a force, and can be more firmly fixed by shrinkage accompanying cooling.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 and 2, reference numeral 1 denotes a straight portion 2 which is formed by bending a material a made of spring steel having a circular solid cross section and which is attached to a vehicle body (not shown), and a curved portion integrally formed on both sides of the straight portion 2. This is a well-known stabilizer which has a substantially U-shape in plan view and a flat portion 4 formed by crushing the ends of both curved portions 3 and having a mounting hole 5 on the wheel side and then heat-treated. .

In FIG. 3, reference numeral 6 denotes a substantially oval positioning member having an insertion hole 8 having an inner diameter slightly larger than the outer diameter of the material a as shown by a chain line, and a relief groove 7 is formed at a corresponding position in the longitudinal direction. Have been.

The positioning member 6 is positioned by aligning the escape groove 7 with the wide flat portion 4 and passing it through the curved portion 3 of the material a, and further moving the linear portion 2 to a predetermined position.

At this time, since the inside diameter of the insertion hole 8 of the positioning body 6 is slightly larger than the outside diameter of the material a, the curved portion 3 and the straight portion 2 can be freely moved.

After the positioning member 6 is stopped at a predetermined position, the insertion hole 8 is reduced by pressing with a press, and is caulked to the linear portion 2 and fixed.

At this time, if the positioning member 6 is energized and heated, the positioning member 6 is heated without adversely affecting the stabilizer 1 by heat, and can be fixed more firmly by shrinkage accompanying cooling.

The material a of the stabilizer 1 may be hollow instead of solid.

In this manner, the linear portion 2 of the stabilizer 1
Is fixed to a mounting member b fixed to a vehicle body (not shown) from the inside as shown in FIG.
The lateral displacement of the stabilizer 1 with respect to the vehicle body from outside is prevented.
