Disc type wheel and manufacturing method thereof

Abstract

The invention discloses a disc type wheel. The wheel rim and wheel spoke welding connecting type of the prior art is replaced by the wheel rim and wheel spoke interference fit and adhering connecting type, the circumferential stress concentration of spoke rods of a wheel spoke can be effectively dispersed by the interference fit, and the capability of the disc type wheel resisting the circumferential stress is improved, so the service life of the disc type wheel is effectively prolonged. The disc type wheel is characterized in that the inner wall of the outer edge of a wheel rim is matched with the convex wall of a first wheel spoke, the inner wall of a support wall of a tire is adhered to a reinforcing wall, a groove is formed in the inner wall of the circle peak of the wheel rim, and the convex wall of a second wheel spoke is arranged on the reinforcing wall and is in interference fit with the groove. The disc type wheel has the advantage that the groove is in interference fit with the convex wall of the second wheel spoke, so the stability of the axial fitting of the wheel rim and the wheel spoke is guaranteed, and the axial stress, circumferential stress and radial stress of the disc type wheel in the use process can be effectively treated.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a web-type wheel and a manufacturing method thereof. Background technique [0002] The spoke wheel includes spokes and rims. During the use of the spoke wheel, it will bear loads in three directions. The first radial load, the radial load comes from the weight of the car body, and the second circumferential load, the circumferential load comes from the car body Braking and braking, the third axial load, the axial load comes from the eccentricity of the wheel fixing part and the wheel curve, and the above three loads are not constant fatigue loads. In the prior art, the welding connection between the rim and the spoke in the bottom of the groove, the radial load has no obvious influence on the weld between the spoke and the rim, the force of the circumferential load on the connecting weld is shear stress, and the weld defect is sensitive to shear stress However, the f...

AI Technical Summary

Problems solved by technology

In the prior art, the welding connection between the rim and the spoke in the bottom of the groove, the radial load has no obvious influence on the weld between the spoke and the rim, the force of the circumferential load on the connecting weld is shear stress, and the weld defect is sensitive to shear stress However, the force exerted by the axial load on the joint weld between the spoke and the rim is tensile stress. It is well known to those skilled in the art that, in terms of the reliability against tensile stress, bolted connection and embedded riveting are the best, and welding The connection defect of welding and bonding is particularly sensitive to tensile stress. Although the structural optimization of the product and process control can reduce stress concentration and welding defects, the effect is limited, resulting in a short service life of the web wheel
