Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlarged view of the utility model；
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of novel rear driven bridge, including axle case assy 9, the side of axle case assy 9 are equipped with semiaxis
2, transmission component is equipped between semiaxis 2 and axle case assy 9, the transmission component includes side and the bridge that axle case assy 9 is arranged in
The bearing block 5 that housing assy 9 is fixedly connected, bearing block 5 are located at the outside of 2 end of semiaxis, are arranged between bearing block 5 and semiaxis 2 double
Row tapered roller bearing 6, the inner ring of double row tapered roller bearing 6 are set in the outside of semiaxis 2, double row tapered roller bearing 6
Outer ring is fixedly connected with the inner wall of bearing block 5, and the port of axle case assy 9 is equipped with mounting groove, is equipped with check washer 11 in mounting groove,
The side of check washer 11 and double row tapered roller bearing 6 is in close contact, the outside installation hex nut 10 of check washer 11, and six
Angle nut 10 fixes check washer 11.
Brake drum 1 is installed, semiaxis 2 is fixedly connected with brake drum 1 by half axle bolt 3 on the outside of the end of semiaxis 2.
Brake 4 is equipped in brake drum 1, the side of brake 4 passes through brake backing plate fastening bolt 8 and brake backing plate
Nut 7 is connect with axle case assy 9 and bearing block 5, and brake 4 is connect by sunk screw 12 with semiaxis 2.
When assembling, first by 4-6 half axle bolt 3 indentation semiaxis 2, double row tapered roller bearing 6 is pressed into bearing block 5
It is interior；It further uses brake backing plate fastening bolt 8 and sequentially passes through the bottom plate of brake 4, bearing block 5, and will be made with hydraulic press
Dynamic device bottom plate fastening bolt 8 fastens；Semiaxis 2 is further used across double row tapered roller bearing 6, is sequentially loaded into check washer 11
And hex nut 10 and hex nut 10 is tightened to defined torque, it then taps 11 exposed parts of check washer and is allowed to deform
And it is bonded hex nut 10 and rivets, rotates back to pine to prevent hex nut 10 vibrated or impact；Further by above-mentioned group
Component penetrates in the corresponding bolt hole of axle case assy 9, screw-in brake backing plate nut 7 is fastened；Further brake drum 1 is worn
