The front wheel of the agricultural transport vehicle oscillated violently, which not only accelerated the wear of the mechanical parts, but also affected the stability of the locomotive, causing the driver to operate fatigue. Therefore, in the event of a serious swing failure of the front wheel of the agricultural transport vehicle, it is necessary to promptly identify the cause and remove it as follows: 1. The ball pin and the pin seat are seriously worn. Should replace the new ball pin and pin seat, careful adjustment of the gap between the ball joints of each steering knuckle, injection of lubricating grease, the front wheel swing phenomenon can disappear. 2. When the front wheel is fixed, the grooved nut is loosened, so that the gap of the tapered bearing changes, causing the front wheel hub to swing. At this time, the bearing clearance should be adjusted according to the technical requirements, and the slotted nuts should be fixed. 3, worm gear, pot rod gap adjustment is improper, and poor lubrication. The worm gear and worm gear clearance should be readjusted as required, and sufficient oil should be injected. 4. If the front wheel rim is not correctly welded, it will also cause the front cymbal to swing violently when the vehicle speed is too high. In this case, the standard wheel should be replaced. 5, the front wheel before the beam is too large or too small, but also prone to severe front-wheel swing, should adjust the toe according to the standard requirements. 6, turn to the vertical arm spline with loose, loose front leaf spring U-bolt can cause the front wheel to swing. After replacing the steering arm and tightening the fixing bolts, the fault is eliminated.
