As shown in fig. 1 to 5, the axle shaft bearing 4 is provided with a bearing positioning gland 7, and the bearing positioning gland 7 is provided with a dust-proof sealing ring 6 for sealing the axle shaft bearing 4.
As shown in fig. 1 to 5, the bearing positioning gland 7 is provided with a hand brake cable bracket mounting support 16 and a brake hard pipe clamp mounting support 15.
As shown in fig. 1 to 5, the inner side surface of the half shaft sleeve flange 3 is provided with a supporting rib 17.
As shown in fig. 1 to 5, the support rib 17 is provided coaxially with the half shaft bearing 4.
As shown in fig. 1 to 5, the rear axle housing is connected to the axle sleeve flange 3, and an end portion of the rear axle housing is inserted into an inner side surface of the axle sleeve flange 3.
As shown in fig. 1 to 5, the rear axle housing and the half axle sleeve flange 3 are connected through girth welding to form a girth welding seam 1, the rear axle housing comprises a rear axle upper housing 10 and a rear axle lower housing 11, an oil seal 2 is arranged in the half axle sleeve flange 3, the half axle 5 is connected with a brake disc 8, and the half axle sleeve flange 3 is connected with a brake caliper 9 through bolts.
In order to meet the requirement of the installation of the brake calipers 9, the half-shaft sleeve flange 3 is changed, as shown in fig. 2, a brake calipers installation support and a brake calipers installation hole 12 are added, and the brake calipers 9 are connected and fastened with the flange of the rear axle housing through bolts; in order to ensure the perpendicularity between the assembled brake caliper 9 and the rear axle housing axis, a brake caliper mounting seat is designed to be machined after welding; the half-shaft sleeve flange 3 is provided with a cutter avoiding fillet 13 for meeting the requirement of a cutter rotation space during processing. As shown in fig. 3, to ensure the chassis weight reduction requirement, the half shaft sleeve flange 3 is provided with a weight reduction groove 14 under the condition of meeting the rigidity.
