Common faults of automobile transmission system
Universal joints and spline loosening abnormal sound performance: the car started, the body shaking, and heard the "grid friends, lattice" crash, in changing the speed, especially in the slow driving, the sound is more obvious The The reason is: universal joint and needle roller wear loose, or needle broken; drive shaft spline teeth and fork tube spline groove wear is too large; transmission output shaft on the spline teeth and flange Spline groove wear is too large; parts of the connection part of the fixed screw loose.
Transmission gear file performance: in the car when the shift, not for the required stalls, or put on the back after the file. The reason is: the interlock device is used for too long, fork shaft, steel ball cross pin wear too much, lost the interlocking effect; shift lever locating pin wear loose or broken, loss of control or shift lever can not be in the correct direction Rotation; the lower end of the shift lever wear too large, so that it can not correctly dial the shift guide block and channeling; output shaft on the retaining ring is not installed or exit, the gear on the axis of any movement caused by channeling file.
Transmission shift performance as follows: in the car when the file driving, the transmission automatically jump back to the gap. The reason is that the inner and outer gears of the gears are too large to be tapered; the spline teeth of the output shaft and the spline groove of the sliding gear are loosened due to excessive wear and tear; the bearing wears too much and the two meshing gears In the movement up and down swing; output shaft five gears often engaged gear bushings and washers wear too large and loose, swing up and down in the movement; output shaft, input shaft stopper ring or lock nut off or loose, causing Shaft or gear before and after the move; shift fork on the self-locking ball wear; groove is too shallow or groove position improper; spring is too soft or spring break; variable fork shaft and variable fork wear or bending.
The clutch is as follows: Whenever the car starts or depresses the clutch, the clutch sounds, and in the combined state, it is generally not sounded. The clutch is loose or the spring is too soft, broken, off; separation of the lever or bracket pin wear loose; clutch friction plate rivet loose, or rivet head exposed; clutch plate spline groove and transmission input shaft spline teeth wear Too large; the clutch pedal of the return spring is broken, too soft or off.
Clutch slippery performance: the car started difficult, driving weakness, acceleration bad, serious will emit the smell or smoke. The cause of the clutch pedal is too small, so that the pressure plate in a semi-combined state; driven plate with oil; friction lining wear serious, hardening, deformation or rivet outcrop; clutch plate spring is too soft or broken, improper adjustment; Cover and flywheel set screw loose; clutch pedal tension spring off or no effect.
