1. When the mixer controls the steering wheel on the way
This is shaking. Generally, when the mixer is moving at medium speed or above, the chassis makes regular noise. When it is severe, the cab and the door shake. The steering wheel vibrates strongly, resulting in hand numbness. This is caused by the damage of the dynamic balance of the direction transmission device and the excessive wear of the drive shaft, spline shaft and spline sleeve of the mixer.
2. The mixer is heavy and laborious when turning
The reasons for this phenomenon are: the cooperation of rolling bearing and sliding bearing in all parts of the steering system is too tight, the bearing is smooth and poor, the ball joint of steering longitudinal rod and tie rod is too tight or lack of oil, the steering shaft and sleeve are bent, causing stagnation, the front toe in adjustment is not proper, the front axle or frame is bent and deformed, and the tire pressure of the mixer is insufficient.
3. The steering wheel of the mixer is not easy to operate
In the process of the mixer's moving, the steering wheel will actively lean to one side of the road, which is caused by several reasons: the specifications of the front wheels on both sides are inconsistent, the camber or spring force of the leaf springs on both sides are inconsistent, and the wheelbase on the left and right sides are not uniform.
4. The direction of mixer truck is floating
The main reason for this phenomenon is that the front wheel swings its head in the process of moving. The main reason is that the dynamic balance of the front wheel assembly is damaged by patching the tire or repairing the tire. There are loose parts in the drive shaft assembly of the mixer, the balance of the drive shaft assembly of the mixer is damaged, the shock absorption is invalid, the spring rigidity of the steel plate is inconsistent, the steering system parts of the mixer are worn loosely, and the front wheel calibration is improper.
