Reasons and Overhaul of Automatic Deviation of Agricultural Vehicles
Automatic deviation of the agricultural transport vehicle will not only make the driver fatigued, but also cause traffic accidents. The reasons and maintenance methods are as follows: 1. After one side of the wheel brakes delays the agricultural vehicle from driving for a distance, touch the brake hubs on both sides by hand. If the side is obviously hot, the braking of the side wheel is delayed. Should check the adjustment of the brake gap, check the brake pedal return spring, brake cam, etc. is issued, and ruled out. Second, one-side wheel hub bearing too tight or stuck, so that the wheel rolling resistance increases after driving distance, touch the bearing at the hand, if you feel obviously hot, that Hu said the bearing too tight, should adjust the bearing tight degree. The method is: lift the front axle, screw the bearing nut to the end, and then return 1/6~1/8 turn, and then wear the split pin. Third, one side of the leaf spring breaks, so that the locomotive tilt to the side should check whether the leaf spring breaks, deformation, dislocation or loose bolts, if necessary, replace. Fourth, the left and right sides of the leaf spring load capacity is inconsistent if the two sides of the leaf spring stiffness is different, the arc is different, the carrying capacity is not the same, will make the locomotive to the leaf spring load capacity weak side tilt, should be replaced. Fifth, the asymmetry of the front wheel alignment If the steering trapezoid is not equal waist, the left (right) knuckle shaft bending deformation, the steering joint shaft and the sleeve with clearance clearance over the Ambassador steering shaft deflection, should be corrected, repair. Sixth, front axle, frame deformation should be corrected. 7. The left and right tires should have sufficient air pressure, and maintain the same tire pressure. 8. The partial load of the cargo should be loaded correctly.
