Light hub with good rigidity

Abstract

The utility model provides a hub with light weight and good rigidity, which comprises a rim and a spoke, the rim and the spoke are mutually connected through welding to form a wheel, one end of the rim is connected with the spoke, the other end of the rim is bent inwards and downwards to form a curled edge, and a noise reduction cavity is arranged between the rim and the spoke. The other end of the rim is further provided with a curled edge, so that the edge of the other end of the rim is curled, the thickness of the rim in the length direction is increased, the curled edge is subjected to upward and inward bending force, force in the transverse direction of the rim is generated, the rigid strength of the rim is further improved from the stress aspect, and the service life of the rim is prolonged. Therefore, the structural strength of the rim can be improved, meanwhile, the situation that the structural strength of the rim is improved by increasing the thickness of the edge of the rim, consequently, machining is complex, and the rigidity strength of the wheel is better is avoided.
