Disc type wheel and manufacturing method thereof

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.
