持する構成であった。The conventional mounting structure of torsion bars for automobile suspension is
As shown in Figures 3 to 3, there are splines la and l on both ends.
The front end of the torsion bar provided with b is connected via a torque arm 4 to a suspension lower arm 3 rotatably supported by a cross member 2a of the vehicle body, and the rear end is iron-coupled to an anchor arm 5. The base end of the arm 5 was supported by the cross member 2b, and the distal end was supported by the cross member 2b via an anchor bolt 6.
第１図において、７はサスペンションアッパーアーム、

いた。In Fig. 1, 7 is a suspension upper arm;
8 and 9 are ball joints, and 10 is a knuckle spindle. In this conventional method, it is necessary to provide a spline at both the rear end of the torsion bar 1 and the base end of the anchor arm 5 that is fitted thereto, resulting in high processing costs.

両者を結合するためのスプラィン加工を不要にし、加工

したものである。Furthermore, since the torsion bar 1 and the anchor arm 5 are manufactured separately, the number of parts increases, and costs inevitably increase in terms of parts management and the like. The present invention was made to improve the above-mentioned conventional drawbacks, and by integrating the torsion bar and the anchor arm,
This eliminates the need for spline processing to connect the two, reducing processing costs and streamlining parts management.
以下、本発明の実施例を第４図乃至第６図に基づいて説
明する。Embodiments of the present invention will be described below with reference to FIGS. 4 to 6.

アーム部１６を一体に形成する。Reference numeral 11 denotes a torsion bar, which has a torsion part 12 in the center, and one end of which is provided with a spline or the like to form an arm attachment part 13, similar to the subordinate torsion bar.
An anchor arm portion 16 is integrally formed by combining the pipe 15 with the anchor arm portion 4 and bending the anchor arm portion 16.

せる。In this case, a flange-like positioning part 17 is provided at one end of the pipe 15, and the pipe 15 is iron-fitted to the other end 14 of the torsion bar 11 so that the positioning part 17 is located at the end of the torsion part 12. At this time, the end surface of the torsion bar 11 and the end surface of the pipe 15 may be aligned as shown in FIG. It may be located at After that, the end 14 of the torsion bar 11 and the pipe 15 are bent together into a U-shape to form an anchor arm part 16, and the base of the anchor arm part 16, that is, near the positioning part 17, is a cross member of the vehicle body. A supported portion 18 is formed for 2b, and a bolt insertion hole 19 is provided at the tip. The above-mentioned bending, drilling, etc. can be easily performed by forging, pressing, etc. The torsion bar 11 configured as described above has an arm mounting portion 13 provided at one end thereof which is fitted to the torque arm 4 using the same mounting means as the conventional torsion bar l shown in FIG. Fixed to suspension lower arm 3,
These are rotatably supported by the cross member 2a, and the supported part 18 at the proximal end of the anchor arm part 16 integrally provided at the other end is attached to a circle provided on the lower surface of the cross member 2b as shown in FIG. Support the two arc-shaped anchor arm supports.
このとき、位置決め部１７をクロスメンバー２ｂの側面

クッション作用を発揮させるのである。At this time, the torsion bar 11 is positioned in the axial direction by, for example, placing the positioning portion 17 against the side surface of the cross member 2b. On the other hand, the upper end of the anchor bolt 23 is rotatably supported in the anchor bolt support hole 21 provided in the cross member 2b via the support member 22, and the lower end of the anchor bolt 23 is inserted into the bolt insertion hole 19 at the tip of the anchor arm portion 16. , and the tip of the anchor arm portion 16 is supported via the support member 24. As a result, a manipulation stress is generated in the central torsion portion 12 of the torsion bar 11 by the rotation of the suspension lower arm attached to one end of the torsion bar 11, and a cushioning effect is exerted by the reaction force.
以上説明した如く、本発明によれば、トーションバーの

ことができる。As explained above, according to the present invention, since the anchor arm portion is integrally formed by iron-fitting the pipe to the other end of the torsion bar and bending it, there is no need for the conventional spline processing for attaching the anchor arm. This eliminates the need for machining costs, reduces the number of parts, facilitates parts management, and reduces costs in this respect as well.

Furthermore, since the anchor arm can be configured to have a double structure using the end of the torsion bar and the pipe, the strength of the anchor arm can be increased.
