Especially, stress concentration occurs around the bolt holes 7 of the disk 3. As a result, fatigue damage occurs around the bolt holes 7, causing cracking as shown in FIG.
There is a problem that 10 occurs. Therefore, in order to increase the strength of the disk 3 of the vehicle wheel 1, in general,
Although the plate thickness of the disk 3 has been increased, increasing the plate thickness of the disk 3 of the vehicle wheel 1 increases the weight of the vehicle wheel 1 and the hub bolt 8 for mounting the disk 3 is easily broken. There is a limit because
For this reason, the disk 3 of the vehicle wheel 1 cannot be sufficiently reinforced, the same crack 10 failure as described above occurs, and the durability performance of the vehicle wheel 1 is insufficient.

In a steel wheel for a truck, a bus, and a light track, which is provided with a disc having a hole, a residual stress region in which a compressive stress remains from a surface to a predetermined depth by wire peening around a plurality of bolt holes of the disc. It is preferable that the residual stress region is a region from a pitch circle passing through the centers of the plurality of bolt holes to a concentric circle having a diameter 1.2 times the diameter of the pitch circle.

からである。Here, the reason that the area around the bolt hole, that is, the residual stress area, is from the pitch circle to 12 times the diameter of the pitch circle is that there are very few crack failures inside the pitch circle, and 1.2 times the pitch circle. This is because in the region beyond the concentric circles, there are few crack failures and the effect of improving the fatigue life is small.

Since the compressive stress remains to a considerable depth from the surface, even if tensile stress (tensile stress) is generated around the bolt holes of the disk due to repeated vibrations and impacts during running of the truck, bus, light truck, etc. The stress is reduced by the amount of the compressive residual stress in the residual stress region, and the strain is also reduced. Therefore, cracking and fatigue damage around the bolt holes are prevented, and durability performance is improved.
Further, since the plate thickness of the disc is not increased, the wheel weight is not increased and the hub bolt is not broken.

力を発生させ、残留応力領域20を形成する。When the compressive stress is left on the surface portion 12c of the disk 12 to form the residual stress region 20, a surface hardening treatment by wire peening is performed. For this wire peening process, as shown in FIG. 3, a wire peening machine 30 using a jet chisel (model JEX-24) manufactured by Nitto Kohki Co., Ltd. was used. The wire peening machine 30 has an air cylinder 32 fixed to an upper plate portion 31a of an upper portion of a frame base 31 having a U-shaped cross section, and a wire peening gun 33 is fixed to a lower end portion 32b of a piston 32a of the air cylinder 32. Has been done. A turntable 35 is provided inside the frame 31, and a vehicle wheel 11 is attached and fixed to the upper side of the turntable 35. The wire portion 33a at the tip of the wire peening gun 33 is the disc 1
It is arranged so as to abut the second residual stress region 20.
The wire part 33a of the wire peening gun 33 has a diameter of 3 mm.
36 are bundled, and the residual stress area 20 can be hit by air reciprocating 4500 times per minute. The wire peening gun 33 is supplied with air through an air hose 37, and the wire 36 of the wire portion 33a of the wire peening gun 33 continuously applies a shock to a portion corresponding to the residual stress region 20 to form a disk.
A compressive residual stress is generated up to a predetermined depth along with work hardening near the surface of the front surface 12c of the twelve, that is, around the plurality of bolt holes 18, and a residual stress region 20 is formed.

-2M type) was used for the so-called X-ray stress measurement. The measurement was performed using a vehicle wheel according to the present invention (the present invention product) and a conventional product with a diameter of 305 m in the residual stress region 20.
The measurement was performed at the position of m and the position of 330 mm in diameter at the surface and at a depth of 30 μm from the surface, respectively. The measurement results are shown in the following table. Minus (-) represents compressive stress and plus (+) represents tensile stress.

コストの加工とすることができる。The vehicle wheel 11 according to the present invention includes a front portion of the disk 12.
The residual stress area 20 is provided in 12c.
Since a compressive residual stress is formed on the vehicle, even if the vehicle wheel is mounted on the vehicle and traveling and severe repeated vibration and impact load act to cause tensile stress, it is erased by the compressive residual stress and the strain remains small. Fatigue of the material of the stress region 20 is extremely small, and no failure due to cracking occurs.
Further, wear due to friction between the bolt hole 18 of the disk 12 and the hub bolt is suppressed. Therefore, the durability performance of the vehicle wheel 11 is significantly improved. Further, since the residual stress region 20 is formed in the flat portion around the bolt hole 18, the machining can be performed by wire peening, which is extremely effective and low cost.
