The fault phenomenon of excessive gap in steering system of flatbed truck: When turning the steering wheel, it feels that the free travel is too large and the steering is insensitive. There are four reasons for the failure analysis: 1) Looseness of the steering gear, 2) Excessive gear clearance of the steering gear, 3) Abrasion of the pin hole of the steering knuckle, 4) Wear and looseness of the tie rod. Corresponding to the troubleshooting there are also four points: 1) tighten the steering gear fixing bolts; 2) adjust the steering gear rack rack clearance; 3) replace the steering wheel steering knuckle steering knuckle; 4) check and timely replacement tie rod ball joint pin. The “drawing dragon†fault means that the flatbed truck is moving and feels that the two front wheels sway from side to side and the steering wheel is difficult to grasp. There are seven reasons for the failure: 1) The tie rod ball head is adjusted too loose (spring break or adjustment gap is too large). 2) The free travel of the steering wheel is too large. 3) The gap between the steering roller and the worm gear is too large. 4) The clearance between the upper and lower bearing of the worm is too large; the gap between the kingpin of the steering knuckle and the bush is too large. 5) The gap between the knuckle kingpin and the bushing is too large. 6) The front wheel hub bearing assembly is too loose, or the front rim is out of round and the swing is too large. 7) The front wheel is misaligned. Judgment and analysis based on the cause of the “drawing dragon†failure caused by the flatbed truck, we can also eliminate one-on-one from this work; 1) replace the tie rod ball head; 2) adjust the steering wheel free stroke until A suitable range; 3) Adjust the meshing gap between the steering wheel and the worm or replace the steering wheel of the flatbed truck; 4) Adjust the worm's upper and lower bearing clearance or replace the steering gear; 5) Replace the kingpin bushing of the steering joint; 69) Replace the front wheel hub bearing and reassemble it; 7) Perform four-wheel alignment.
