The main reason for the oil leakage in the driving axle of Baotou heavy truck fittings is:

(1) the gas in the axle housing is too much to exceed the normal height or the lubricant is spoiled; the bolts of the connecting parts of the shell are loosely advised.

(2) Baotou North rush heavy truck parts on the bridge shell vent holes, when driving, due to rising oil temperature, internal pressure increases, the oil has been extruded; oil or oil plug did not press the torque tightening.

(3) pinion front seal edge, shaft neck wear and damage; the axle seal is arranged on the half sleeve seat hole, and rubber aging causes between seal edge and shaft seal bad; the driving gear is installed before the oil seal.

(4) bearing loose ends, differential axle bearing looseness of the upper and lower jitter, or half shaft bending deformation of the oil seal edge wear damage lose oil sealing effect; gear flange looseness; insufficient gear shaft neck tension.

All of the above causes the drive axle to leak oil. The harm will be the main reducer and differential lubrication even without oil lubrication, increased mechanical wear, causing parts of early damage; oil seal leakage will damage the half shaft into the brake chamber, or into the wheel reducer (Steyr and Benz diesel car) the level rises, the seal was washed out into the brake room, due to poor braking, endanger traffic safety. Therefore, the following work should be done to prevent it:,

(1) check Baotou beiben heavy truck parts in drive axle gear oil is too much or deterioration, such as should be appropriate to release gear oil to the specified standard or replacement; check the gas plug or the oil drain plug is not tight, as should be required to tighten the bolt tightening torque; if the oil level is reduced, in addition to outside also, we should find out the reason, to be repaired.

(2) cleaning the ventilator regularly to ensure good ventilation performance.

(3) strengthen the inspection and adjustment of the wheel bearings and differential bearings, and check the half shaft straightness and the shaft neck roundness, and ensure that the axle does not vibrate and swing when it rotates, so as not to damage the oil seal.

(4) when the oil leakage at the shaft of the driving gear is found, if the connecting flange of the driving gear is loose, it will be tightened; if the oil seal is worn or damaged, it should be replaced in time.

(5) often pay attention to seal the axle seal, once found in the drive axle oil decreased or wheel reducer level increased, and the brake with traces of oil, or in the article (3) work, all should check the oil seal intact, replace if necessary. Replacement, in addition to the selection of qualified oil seal, but also should be properly installed, so that it does not install anti -, non – askew, do not damage the blade, we must pay attention to the spring stretch of the oil seal, both small, but also large.
