Meanwhile, the precision of laser softening treatment is high, and the processing efficiency of the softening treatment is improved.
As shown in fig. 1, in order to sufficiently reduce the structural strength of the screw hole position of the spoke blank, the coupling strength of the nut is ensured. The screw hole of the spoke blank is a circular softening area, the radial size of the circular softening area is larger than that of the screw hole, and the difference between the radial size of the circular softening area and the radial size of the screw hole is in the range of 0-5 mm. The difference between the radial dimension of the circular softened area and the radial dimension of the threaded hole is 0 or 1mm or 2mm or 3mm or 5 mm.
The present application also provides a wheel, which, as shown in fig. 2 to 4, includes wheel disc 10 and rim 20. Spoke 10 is welded to the inside of rim 20, and the strength of the screw hole position of spoke 10 is between 500MPa and 1050 MPa. The strength of the screw hole between 500MPa and 1050MPa effectively reduces the strength of wheel disc 10, and enables the strength of wheel disc 10 to match the strength of the nut while ensuring the weight reduction of the wheel. Preferably, the strength of the screw hole locations of wheel disc 10 is between 600MPa and 900 MPa. The strength of the screw hole position of spoke 10 is specifically 600MPa or 800 MPa or 900MPa or 1000 MPa.

The screw holes of the spokes 10 are located on the annular projection, and the screw holes 15 are provided at the screw holes of the spokes 10. The provision of the annular projection provides the mounting section 11 with sufficient structural strength.
As shown in fig. 3 and 4, in order to improve the reliability of fastening the wheel disc 10, the screw holes 15 are plural, and the plural screw holes 15 are arranged at intervals in the circumferential direction of the annular projecting portion.

In the application, the rim comprises a rim body and a bending flange, the bending flange is connected with the circumferential edge of one axial end of the rim body, bends and extends along the radial direction of the rim body and then is attached to the end section 14 so as to form a combined part with the spoke, and the axial width of the combined part is more than or equal to 5mm and less than or equal to 25 mm. Thus, when the end section 14 is welded to the bent flange, the size of the above-mentioned joint portion enables the end section 14 to have a sufficient contact area with the bent flange, ensuring the joint effect and ensuring sufficient connection strength between the spoke and the rim.
In the present application, the middle section 13 is a spoke, a first end of the spoke is connected to the transition section 12, and a ratio of a length of a second end of the spoke in a circumferential direction of the rim to a circumferential length of the rim is equal to or greater than 1/48 and equal to or less than 1/12. Like this, through optimizing the ratio of the ascending length in circumference of the rim of edge of the second end of spoke and the circumferential length of rim, avoid leading to the ascending length undersize of spoke edge rim in circumference because of the ratio undersize between the two, ensure that the welding bead structure between spoke and rim is enough long on the circumferential direction of rim, thereby guarantee welding stability between the two, can also avoid leading to the spoke to be too big along the ascending length in circumference of rim because of the ratio between the two is too big, ensure that ventilation hole 17 has enough big overflow area.
Preferably, the ratio of the length of the second ends of the spokes in the circumferential direction of the rim to the circumferential length of the rim is 1/24.
Optionally, the number of spokes is not less than 4 and not more than 20. In this way, while ensuring that the spoke 10 can provide a stable support for the rim, it ensures that the ventilation holes 17 have a sufficiently large flow area.
The application also provides a vehicle, and in the embodiment, the vehicle comprises wheels, and the wheels are the wheels. Since the wheel can ensure the light weight of the wheel and can match the strength of the spoke with the strength of the nut, the vehicle with the wheel can achieve the same effect.
