Car steering bevel gear assy and differential failure symptoms:
The main gear assy steering bevel and differential are generally an assembly. The main function of the main steering bevel is to reduce speed, increase torque, and improve driving force. Rear-wheel drive vehicles also change the direction of power transmission through the steering bevel and bevel teeth of the main gear assy! The left function of the differential is to distribute power to the left and right wheels to ensure that the left and right wheels rotate at different speeds when the vehicle turns!
HDAG Analysis and repair methods for rear axle main steering bevel failure:
When a vehicle is driving, various emergencies often occur, such as the vehicle not moving after shifting into gear. At this time, we must first consider whether there is a problem with the half shaft. Generally, the half shaft splines are twisted. Or if it breaks, it will not mesh with the gear, and it will not move after shifting into gear. At this time, we’d better find a local repair station to replace a half shaft. However, the most important phenomenon of steering bevel gear failure is the problem of abnormal noise. Its specific manifestations are as follows:
1. The vehicle makes abnormal noise while driving.
Manifestation: The teeth of the active and passive gears are broken and broken. Treatment method: Replace the pair of active and passive gears, and replace the gear oil.
Manifestation: Improper clearance between active and passive gears. It makes a buzzing sound when running, and if the steering bevel shell is hot to touch after driving for a certain HangZhouage, it indicates that the gear clearance is too small. When starting, the bridge makes a choking sound, the sound is very small, and the sound increases when changing speed, indicating that the gear gap is too large. Solution: Adjust the gap between the active and passive teeth.
2. Abnormal noise occurs when going up or downhill.
Manifestation: The meshing marks of the active and passive gears are incorrect. Solution: If there is abnormal noise when going uphill, check the convex surface of the passive gear and adjust the mark of the passive gear. Abnormal noise when going downhill mainly depends on the mark on the concave surface of the driven gear. If the noise is not loud, try not to adjust it. Check whether the tooth side clearance is out of tolerance. If the noise is loud and the concave mark is very incorrect, rely on both ends or the top of the tooth root. The adjustment is opposite to the convex surface. .
3. Abnormal noise occurs when turning.
Manifestation: The bearings at both ends of the differential case are loose. There are messy sounds coming from the differential case, mostly caused by loose differential bearings. Solution: Adjust or replace the differential bearing.
Manifestation: Poor planetary gear meshing. The differential makes a whistling sound when turning and a buzzing sound when driving straight, indicating poor meshing of the row side teeth. Solution: Replace the planetary gear.
The above analysis is mostly based on the manifestations of the abnormal noise of the steering bevel gear assy. Its treatment method has found a better solution for the abnormal noise of your car, so that the driving safety of the car is better guaranteed.
