Abstract

PURPOSE:To improve strength and durability of a joint part of a hollow stabilizer for an automoble, by welding a base end of a joint component to the end of a hollow and cylindrical main body by friction and pressure. CONSTITUTION:A stabilizer main body 1 is formed of a hollow and cylindrical unit, and connecting components 2 and 2 are jointed to the both ends in a body. At the time of jointing, the end part of the main body 1 is brought face to face with a base end part 5 of the connecting component 2, pressure is applied axially and they are revolved relatively in a state where confronting ends are touched mutually by pressure. Burrs 7 and 8 to be generated on this ocasion are removed by an appropriate device for them and then bending process, heat treatment and painting are applied to the stabilizer. With this, bending and torison strength and durability are improved without affecting badly to a threaded rod 4a and recognizing harmful remnants, such as a blow hole and an oxide in a joint part.

いる。Stabilizer bars for automobiles tend to be formed in a rounded hollow shape to reduce weight, but with a hollow rod shape, it is difficult to manufacture a connection part that connects to the wheel side. Pre-formed connecting members are joined together.

することにある。However, the conventional method of fitting the proximal end of the connecting member into the hollow part of the main body and welding requires post-heating operations and equipment for the welding part in order to prevent weld cracking. Also, the strength and durability of the finished product are likely to vary.
In addition, in the case where the main body and the connecting member are connected by screws (Utility Model Application No. 55-29773), stress concentration tends to occur in the troughs of the screws, resulting in poor durability and capillarity in the screw portions. Moisture infiltrates into the main body, which causes rust.Furthermore, in the case where the connecting member is press-fitted into the hollow part of the main body (Utility Model Application Publication No. 153207/1983), the gap caused by the compression Stress is concentrated in the parts, which may impair durability, and since the parts are hollow and it is difficult to completely seal them, rust is likely to occur due to moisture infiltration.'' The present invention was made under the above circumstances. The purpose is to provide a hollow stabilizer for automobiles that is easy to manufacture, compact, low cost, and of excellent quality.

。The present invention is characterized in that the proximal end of the connecting member is joined to the end of the hollow rod-like main body by friction welding. Therefore, unlike conventional welding, deterioration of the product due to the adhesion of adhesive in the welding process does not occur, and it is possible to reduce man-hours and equipment costs. death,
In addition, there are no porosity oxides or other inclusions in the pressure welded part, the hollow part is completely sealed, and stress concentration can be eliminated, so the strength and durability of the joint are maintained at a high level. It also reliably prevents rust caused by moisture intrusion.

In the figure, the stabilizeripe main body 1 is formed from a hollow rod-like material in a roughly U-shape, and connecting members 2.2 are integrally joined to both ends. The linear intermediate portion 3 of the main body 1 is supported by the vehicle body side of the automobile (as shown), and the distal end connecting portion 4 of the connecting member 2 is connected to the wheel 1m (as shown) by rc. The connecting portion 4 may be a threaded rod 4a as shown in FIG. 2, or a center portion 4b as shown in FIG. 3, and may be set as appropriate as required. .

上述のような中空スタビライプを製造する場合にはまず
直線状のままの本体１と連結部材２との接合を行なう。When manufacturing a hollow stabilizer rope as described above, first, the main body 1 and the connecting member 2, which remain straight, are joined together.

In order to avoid concentration of stress in the recess 6, it is preferable that the bottom surface be formed into a spherical or conical shape as shown in the figure, but a simple cylindrical shape may be used if necessary.

A pressing force in the axial direction is applied to the two concentrically opposing surfaces, and the opposing surfaces are rotated relative to each other in a state in which they are in pressure contact with each other. In this case, either one of them may be rotated, or both may be rotated in the opposite direction.If friction welding is performed in this way, the joint part will be rotated as shown in Fig. 4.
8 is generated, so the pari 1 on the surface is removed by appropriate means. Thereafter, by performing various necessary steps such as bending, heat treatment, and painting, a desired hollow stabilizer rope as illustrated in FIG. 1 can be obtained.

。According to the above structure, since the main body 1 and the connecting member 2 are friction-joined, unlike welding, there is no possibility that the base ivy will have an adverse effect on various parts, especially the threaded rod 4i, etc. Moreover, no harmful residues such as air bubbles or oxides were observed in the joints, and as a result of testing for bending and screw strength, durability, etc., the maximum values were almost the same for both, and the variation was larger in the case of friction welding. 173 compared to welding
~174, and the quality level is extremely high and stable. Furthermore, the number of man-hours required is small and the equipment cost is low, contributing to cost reduction. Furthermore, since the joints are completely closed, the ingress of moisture and the like can be reliably stopped and rust can be prevented. Furthermore, since the recess 6 is provided in the base end 5 of the connecting member 2, it is also possible to prevent localized stress concentration by appropriately setting the shape of the recess 6. .
