Internal torque load stop

1. Full parking, shift to the neutral file, then change to high-end (H), when the high-lock file is not changed (H), the vehicle cannot be driven in a hard road;

2. The work oil used is incorrect or the work oil is insufficient, and the corresponding replacement is carried out;

3. If the isometric universal transmission shaft creates a break or failure, when the vehicle does not travel, the mating (HL) gear can continue to travel, and should be found in time to repair the relevant unit repair vehicle.


Main driver failure and exclude

Main driver gear meshing does not normalize

1. When the car starts, \"\ \" sound occurs, when the car is shifting the instant or drag of the car, and the speed is relatively stable, the sound is reduced or disappeared, and the exclusion of the transmission axis is diagnosed as The main, the slave gear gap is too large, and adjustment can be adjusted by reducing the adjustment gasket;

2. If a continuous gear occlusion sound is issued within Axle, its frequency increases with the speed of the vehicle, especially when driving in the car, the sound is large, and when the acoustic sound is reduced, The parking is very hot, and the gear gap is too small, or when the engagement of the printed adjustment is not properly adjusted. This phenomenon should be re-adjusted after the automotive maintenance or replacement of the gear;

3. In order to ensure the accuracy of the diagnosis, the drive bridge can be identified. Main drum oil leakage

1. If there is discovered traces of lubricating oil from the vent, there may be too much oil, and you should check from the oil surface scrap and excess gear oil;

2. If the oil is leaked from each combined surface, the venting hole should be dredger, and then check the bolts of each combined part;

3. If the oil sealing oil should be replaced in time.


Steering system failure and exclusion

Turning heavy, boosting

1. The oil tank is deficieted, check if there is an oil leak, if it is eliminated, it is filled with oil according to the regulations, otherwise it will be filled with oil according to the regulations;

2. The oil pressure circuit (i.e., engine steering power pump to the power pump to the power steering) is infiltrated into the air;

3. The sealing of the oil pipe joints has a leakage phenomenon, and the oil passage is blocked or the oil filter is too much, the oil pump is worn, and the internal leakage is severe;

4. Safety valve leaks, spring elasticity is weak or modified, the power cylinder or steering control valve seal is damaged;

5. First check if the oil pump belt is slippery, then check if the oil pump safety valve is adjusted, if necessary, the oil pump is replaced, check whether the oil pressure or flow of the engine boost the pump is insufficient;

6. tyre The air pressure is too low, the steering gear is used is too tight, horizontal, straight rod ball sales equipped with too tight or lack of oil, the front torch adjustment is improper, will cause the vehicle to undressing, Diagnostic repair.


The vehicle is unilateral steering

1. The steering control valve valve core deviates from the intermediate position, or although in the intermediate position but does not result in different sizes of the gap of the valve body trough, it is necessary to replace the steering control valve, notify the service station processing;

2. The turn to the vertical arm is not properly assembled on the output shaft of the steering machine, and is not installed according to the mark;

3. The front wheel side reducer steering angle limit bolt length is large, resulting in a small wheel steering angle;

4. Turning stabilizing rod mounting position offset causes the side tie rod and the lateral stabilizing rod gap to generate interference, resulting in a small wheel steering angle.


Steering wheel

1. It is necessary to re-do four-wheel positioning, ie the inclination angle, outer tilt angle, front beam value, etc. These parameters directly cause the shoulders of the vehicle tyre to be partial or wear as a saw tooth shape, such defect tyre causes dramatic beating during high speed, thereby causing a swing and beating in the steering wheel;

2. You need to check whether the upper and lower balls of the vehicle wheel speed reducer will be loose, turned to the side tie rod, turning to the vertical arm, and the arms and other ball heads are connected;

3. Check the moving balance between the wheel without loss or re-tyre.
