There is the dust-proof seal ring 6 for sealing the axle bearing 4.
As shown in Figures 1 to 5, the bearing positioning gland 7 is provided with hand brake stay cable support erection support 16 and braking is hard
Pipe pipe clamp erection support 15.
As shown in Figures 1 to 5, the medial surface of the axle tube flange 3 is provided with support convex tendon 17.
As shown in Figures 1 to 5, the support convex tendon 17 is coaxially disposed with the axle bearing 4.
As shown in Figures 1 to 5, the rear axle housing is connected with the axle tube flange 3, the end insertion of the rear axle housing
The medial surface of the axle tube flange 3.
As shown in Figures 1 to 5, connected between the rear axle housing and the axle tube flange 3 by boxing, form boxing
Seam 1, the rear axle housing include back axle upper shell 10 and back axle lower house 11, oil sealing 2, institute are provided with the axle tube flange 3
State semiaxis 5 and be connected with brake disc 8, the axle tube flange 3 is connected by bolt with the brake caliper 9.
To meet the installation of brake caliper 9, axle tube flange 3 is modified, as shown in Fig. 2 increase brake caliper
Erection support and brake caliper mounting hole 12, brake caliper 9 is connected by fastening with the flange of rear axle housing by bolt；To ensure to fill
With rear brake caliper 9 and rear axle housing axis verticality, brake caliper mounting seat is designed as postwelding machining；Axle tube flange 3
Cutter rotary space during to meet to process, cutter avoidance fillet 13 is provided with axle tube flange 3.As shown in figure 3, to ensure
Chassis lightweight requirements, axle tube flange 3 are provided with lightening grooves 14 in the case where meeting rigidity.
