Detailed Description
The utility model is described in further detail below with reference to the drawings and the specific examples.
1-5 Show a novel weight-reducing rear hub of the structure of the utility model, which comprises a rear hub body 1, a hub flange 8, a tire bolt press-fit hole 12 and a brake disc bolt threaded hole 5 which are integrally connected, wherein: the rear hub body 1 is provided with a bearing hole 4, a snap ring mounting groove 3 and an inner oil seal mounting step hole 2 are arranged on the inner side (i.e. the right side in fig. 1) of the bearing hole 4, and a weight reduction cavity 7 and an outer oil seal mounting step hole 6 are arranged on the outer side of the bearing hole 4; the edge of the hub flange 8 is internally and uniformly provided with a first weight-reducing arc 10, and the edge of the rear hub body 1 is internally and uniformly provided with a second weight-reducing arc 9; a plurality of tire bolt press-fitting holes 12 are uniformly formed in the circumferential direction of the hub flange 8, and a plurality of reinforcing blocks 11 are integrally formed or welded at positions of the hub flange 8 corresponding to the tire bolt press-fitting holes 12.
