How much is the direction machine of heavy truck HOWO mine
According to the models, the prices of original parts, accessory parts and refurbished parts vary greatly. The prices of low-end models generally range from 600 to 2000, and the prices of middle and high-end models are doubled
judgment method:
1. It is difficult for the steering wheel to return to its original position:
generally, the steering wheel of vehicles has the function of automatic return to its original position. For vehicles equipped with hydraulic power steering machine, the function of automatic return to its original position is weakened e to the effect of hydraulic damping, but if the speed of return to its original position is too slow, it means that the function of return to its original position is faulty
2. Direction shaking or deviation:
when the car runs on one side of the donor Road, it has a tendency of deviation. When the arch is larger, the deviation is more obvious, which is caused by external factors. After eliminating the problem of tire pressure, it is likely to be caused by the loosening or fracture of a mechanical part of the steering gear
3. The steering wheel is light while heavy:
when driving the steering wheel, I feel that the steering wheel turns light while the other half turns heavy. This symptom is generally caused by the leakage of the seal of the high pressure chamber on the sealing side, and another possibility is that the limit valve in this direction is not adjusted properly

precautions:
I. hand numbness ring driving. When the vehicle is running at a speed above medium speed, the chassis makes periodic noise. In serious cases, the cab and door tremble, and the steering wheel vibrates strongly until the hands feel numb. This is e to the damage of the dynamic balance of the steering gear and the excessive wear of the transmission shaft and its spline shaft and spline sleeve
Second, the steering is heavy and laborious. The causes include tight fit of rolling bearings and sliding bearings in various parts of the steering system, poor lubrication of bearings, tight adjustment or lack of oil of ball heads of longitudinal and transverse steering rods, bending of steering shaft and sleeve, resulting in stagnation; Improper adjustment of front wheel toe in; The frame is bent and deformed; Insufficient tire pressure, especially the front tires Thirdly, the steering wheel is difficult to operate. When driving or braking, the direction of the vehicle automatically deviates to one side of the road. In order to ensure straight driving, it is necessary to hold the steering wheel firmlyby 2020, the replacement cost of a steering gear is about 800-6000 yuan
{rrrrrrr}
extended data:
if the steering gear is broken, it may be the following faults, which can be checked first:
1. The rubber sleeve of the lifting lug of the chassis suspension balance bar is aging and hardening, and the friction ring rotation causes the abnormal noise of the steering gear
2. Open the engine hood and check whether the steering oil is less or deteriorated
3. The steering column is not lubricated, the friction is high, and the steering gear makes abnormal noise
Check the plane bearing for deformation and damage; Check if there is any problem with the universal joint and the ball cage5. The gap between gear and rack is too large, and the friction is abnormal
1. There are only several locations for the steering gear to leak oil: the upper cover of the steering gear, the side end cover and the connecting part of the steering shaft crank arm. These three parts have sealing rings, which can be solved by replacing the new oil seal and sealing ring
2. If there is oil leakage in other parts, it is likely to be trachoma or crack in the steering gear housing. Small cracks and trachoma can be plugged with loctite 290 high permeability sealant
3. If there is still oil leakage after changing the sealing gasket or sealing sealant, the steering gear assembly needs to be replaced.
in addition, do not drive too hard when driving, and try not to hit the wheel in place as much as possible. Often, the oil seal will be washed and pulled, causing damage to the steering gear and oil leakage. How much depends on the model!
generally, the auxiliary factory has a warranty of about one year,
