The causes of abnormal noise in the transaxle mainly include the following:
Improper gear meshing clearance: Too large or too small gear meshing clearance will cause abnormal noise. When the gap is too large, the car will make a “clucking” or “coughing” sound while driving; when the gap is too small, the higher the speed, the louder the sound, accompanied by heating.
Bearing problem: The bearing clearance is too small or the differential case support bearing clearance is too large, which will cause abnormal noise. If the bearing clearance is too small, the drive axle will make a sharp sound accompanied by heating; if the bearing clearance is too large, the drive axle will make a messy sound.
Loose rivets of the driven bevel gear: Loose rivets of the driven bevel gear will cause rhythmic abnormal noise, usually manifested as a “hard” sound.
Wear of side gears and side splines: Wear of side gears and side splines will cause the car to make noises when turning, but the noise disappears or is reduced when driving in a straight line.
Gear teething: Gear teething will cause sudden noises, requiring the vehicle to be stopped for inspection and replacement of related parts.
Poor meshing: The differential planetary gear and the side gear do not match, resulting in poor meshing and abnormal noise.
Insufficient or improper lubricating oil: Insufficient or improper lubricating oil will cause the gears to grind dry and make abnormal noises.
The function of the drive axle and common fault phenomena:
The function of the drive axle and common fault phenomena:
The transaxle is a mechanism located at the end of the drive train that can change the speed and torque from the transmission and transmit it to the drive wheels. Common fault phenomena include damaged gears, missing teeth or unstable meshing, etc., which can cause abnormal noise. Resonance may also cause abnormal noise, which is usually related to the structural design or installation of the drive axle.
