When the tractor's steering, braking, transmission system and suspension devices are working properly, the driver feels very comfortable holding the steering wheel. Sometimes he can loosen his hand for a short time and the vehicle can still run straight. If the above device malfunctions, the driver will feel abnormal when manipulating the steering wheel.
First, the hand is numb during driving. When the vehicle is traveling at a speed above mid-speed, the chassis may experience periodic sounds or strong steering wheel vibrations, causing the driver's hands to numb. This is due to the destruction of the directional drive balance and excessive wear of the drive shaft and its splined sleeve.
Second, heavy and laborious steering. The reasons are as follows: 1. The rolling bearing and the sliding bearing in each part of the steering system are over-tightened and the bearing is poorly lubricated; 2. The ball pin of the steering longitudinal and die pull rod is over-tightened or lack of oil; 3. The steering shaft and the casing are bent Stuck; 4, improper adjustment of the front wheel toe; 5, front axle or frame bending, deformation; 6, tire pressure is insufficient, especially the front tires.
Third, the steering wheel is difficult to manipulate. When driving or braking, the direction of the vehicle is automatically biased toward the side of the road, and the steering wheel must be firmly held to ensure straight running. The causes of vehicle deviation are: 1. The front wheel specifications or air pressure on both sides are inconsistent; 2. The front wheel kingpin caster or wheel camber on both sides are not equal; 3. The front wheel hub bearing clearances on both sides are inconsistent; 4, the two sides of the steel plate spring arch or elastic inconsistent; 5, the left and right sides of the wheelbase difference is too large; 6, the wheel brake gap is too small or out of round brake drum, resulting in a side brake issued, so that the brake drag; 7 , Vehicle loading uneven.
Fourth, the direction of hair floating. When the vehicle reaches a certain high speed, there are some reasons for the steering wheel to tremble or swing: 1, shimming the tire or rim repair caused the balance of the front wheel assembly is destroyed; 2, the transmission bearing assembly parts loose; 3, transmission The total balance of the shaft is destroyed; 4, the shock absorber fails, the leaf spring stiffness is inconsistent; 5. The wear and tear of the steering system is loose; 6. The front wheel is improperly calibrated.
