Vehicle wheel hub

A wheel for vehicle, having a wheel front side located on an outer side of a vehicle and a wheel back side located on an inner side of the vehicle in a mounting state, a main body of the wheel comprising a flange including a first flange on the wheel front side and a second flange on the wheel back side, a rim, spokes, a center hole, and bolt bores distributed around the center hole, the rim having a diameter and a width suitable for mounting a tire, and two sides of the rim being defined by the first flange on the wheel front side and the second flange on the wheel back side, wherein an extension part is added to the first flange on the wheel front side, the extension part comprises a radial extension magnitude extending to the outer periphery of the wheel and an axial extension magnitude extending to the wheel front side, the extension part comprises a plurality of sections spaced apart from each other along a circumferential direction of the first flange, and when viewed from a front view along a direction of a central axis of the wheel, the sections are protruding from the second flange, thus forming an envelope circle on the wheel front side with the diameter increasing by two times the radial extension magnitude;

• the extension part is axially offset outwards relative to the first flange to provide axial assembly space for the tire, and the value of the axial offset increases with the increase of the axial extension magnitude and the radial extension magnitude.
