Sun gear 9 is driving link, and it is connected with semiaxis 1 with spline, transmits the rotating speed and moment of torsion come from main transmission.Planet carrier
8 be driven member, and it is connected with brake drum 5, wheel hub and wheel.Gear ring 17 is fixed, and it passes through gear ring support and bridge
Shell is connected with spline, gearratio i=Zr/Zs+1.Zr and Zs are respectively the number of teeth of gear ring and sun gear in formula.By taking turns cardiac skeleton
The bearing capacity of tire is transferred on axle housing, load is evenly distributed, allows semiaxis and sun gear to be completely in quick condition, is not added with
Any supporting, improves sun gear and planetary meshing condition；Now, sun gear together with half shaft end by being arranged symmetrically
Several planetary gears are in equilbrium position to the radial load of the mutual balance of sun gear.
