The utility model discloses a driven axle for leveler, a left side / right side wheel limit subassembly assemble left and right inclination joint through the round pin axle on, left bank joint and right bank joint are respectively through the round pin hub connection in the pontic both sides to realize from driving wheel slope function, the steering linkage subassembly includes double piston rod double -acting cylinder, connects ball seat, pull rod, ball pivot, wherein double piston rod double -acting cylinder both ends respectively through the hydro -cylinder leg joint on the pontic, double piston rod double -acting cylinder links to each other through connecting ball seat and pull rod, the both ends of pull rod link to each other with revolver limit subassembly, right side wheel limit subassembly through the ball pivot respectively, realize driven rotating to the function. Wheel limit subassembly makes the bridge can bear bigger load, guarantees the leakproofness of bearing, the maintenance time of having reduced user's bridge, has improved the life of bridge, the effectual rotation problem of having avoided at the big little double piston rod double -acting cylinder pole of load of steering linkage subassembly.
