てｆはその溶接部を示す。 However, in this type of conventional torsion spring device, the attachment of the arm e to the torsion bar b or the fixation of the end portion c can be firmly connected by means of fixing means using well-known serrations. There is no suitable means for firmly connecting the tube a and the anchor arm d, and conventionally the anchor arm d has generally been fixed to the torque tube a by welding. In FIG. 1, f indicates the welded portion.

を伴なうという問題があつた。 However, conventional joining methods using welding may result in defects due to insufficient metal penetration and blowholes, which are unique to welding, as well as adhesion of spatters to the torque tube that occur during welding, or weld beads. There was a risk that fatigue life would be reduced due to stress concentration caused by the notch. In addition, it is technically difficult to conduct non-destructive inspections for insufficient metal penetration and blowholes in welds, to completely prevent spatter, and to control the shape of weld beads. There was a problem.

してある。 First, as shown in FIG. 3, the mounting ring portion 4b is integrally formed with anti-rotation uneven portions 5 on its inner peripheral surface in advance. This anti-rotation uneven portion 5
For example, a serration is adopted, and the diameter D 1 (shown in Figure 3) of the inscribed circle of the unevenness is slightly larger than the outer diameter D 2 (shown in Figure 4) of the torque tube 1. Make it. As an example, in this embodiment, the tube outer diameter D 2 = 38.1 mm, while the ring part inner diameter D 1 =
39mm, module 1.0, serration with 40 teeth. Furthermore, in order to prevent the torque tube 1 from moving in the axial direction, one or more annular grooves 6 are formed in the anti-rotation uneven portion 5 along the circumferential direction.

Torque tube 1 is held by molds 10 and 11 so as to be in a predetermined position with respect to b.

ている。 Next, the pad 12 is inserted into the torque tube 1. This pad 12 has a length that allows it to be inserted to the location where the anti-rotation uneven portion 5 is located, as shown in FIG. In addition, the above guess money 1
2 has a substantially cylindrical shape, its outer peripheral surface 12a is slightly spaced from the inner surface of the torque tube 1 (exaggerated in the drawing for ease of understanding), and has a slightly tapered shape. ing. The outer diameter of the base 12b of the pad 12 is the same as that of the torque tube 1.
A striking portion 12c is integrally formed on the base portion 12b. This striking portion 12c is provided with a stepped portion 12d that comes into contact with the end surface of the torque tube 1, and this stepped portion 12d allows the torque tube 1 to
It is designed so that a load can be applied in the direction (axial direction).

て強固な回り止めとなる。 Therefore, when the striking portion 12c is strongly pressed in the direction P in the figure and the torque tube 1 is compressed in the axial direction, the wall thickness of the torque tube 1 is locally reduced between the outer circumferential surface 12a of the stopper 12 and the anti-rotation uneven portion 5. The outer peripheral surface of this portion is strongly pressed against the anti-rotation uneven portion 5. As a result, plastic flow occurs, and the outer surface of the torque tube 1 bites into the anti-rotation uneven portion 5.
As shown in FIG. 5, the anti-rotation uneven portion 5 is firmly integrated with the torque tube 1. Therefore, it becomes an extremely strong rotation stopper.

きる。 Furthermore, since the outer surface of the torque tube 1 also bites into the annular groove 6 along the circumferential direction of the torque tube 1, movement of the anchor arm 4 in the axial direction of the torque tube 1 can be reliably prevented.

ることができるものである。 Thus, according to the above method, the mounting ring portion 4b and the torque tube 1 are mechanically integrated using plastic flow instead of conventional welding, so that various types of problems caused by welding as described above can be avoided. The problem can be solved and a high-quality and highly reliable connection can be obtained.

できる。 In addition, before setting the torque tube 1 in the molds 10 and 11, if the part to be pushed out is heated locally by an appropriate length in advance, and the part is pushed out in the warm or hot state, it will be possible to spread out the part in the cold state. Plastic flow to the anti-rotation concavo-convex portion 5 can be made more likely to occur than if the deformation is performed.

にしてもよい。 Further, in the embodiment described above, the annular groove 6 is used as a means to prevent the mounting ring portion 4b from moving in the axial direction.
However, instead of providing such a groove 6, for example, as shown in FIG. 6, protrusions 13, 13 are provided on the outer surface of the torque tube 1 to prevent the axial movement of the mounting ring portion 4b. You may also try to stop it.

Needless to say, a rotation-preventing uneven portion can be used.

である。 As described above, the method of the present invention involves inserting a pad into the inside of the torque tube where the anti-rotation uneven portion is located and applying pressure to the torque tube from its end. While restraining the inner diameter of the anchor arm, the wall thickness of the torque tube expands between the outer surface of the stopper and the anti-rotation uneven part, and the outer surface of the torque tube bites into the anti-rotation uneven part of the anchor arm by plastic flow, making it firmly integrated. It was designed to make it easier to understand.
Therefore, instead of conventional welding, the anchor arm and torque tube can be connected mechanically, which eliminates defects caused by insufficient metal penetration, blowhole formation, and adhesion of spatter to the torque tube, which are problems in welding. In addition, it is possible to eliminate the reduction in fatigue life due to stress concentration caused by notches in the weld bead portion, etc., and it is possible to obtain a high-quality and highly reliable torsion spring device. Moreover, an annular thick-walled part along the circumferential direction of the torque tube is integrally molded at the attachment part of the anchor arm to the torque tube, and this thick-walled part reinforces the connection part between the torque tube and the mounting ring part. This allows sufficient connection strength to be exerted even against large torsional torques. Since the outer surface of the torque tube is forced into the anti-rotation uneven part by plastic flow and integrated, there is no need for high-precision machining of the anti-rotation uneven part, and when forging the anchor arm, etc. It is also possible to perform molding processing at the same time, which is effective in reducing productivity and processing costs.
