According to the structural characteristics of the semi-trailer axle, it can be divided into integral type and disconnected type. The integral structural feature is like a large barbell, and the two ends support the body through the suspension system, so the integral semi-trailer axle is usually matched with the non-independent suspension; the disconnected structural feature is like two umbrellas It is inserted on both sides of the body, and then the body is supported by the suspension system, so the disconnected semi-trailer axle is used with the independent suspension. In the application of semi-trailer axles, oil leakage is a common fault, and how to prevent and troubleshoot is very important.
1. Too much gear oil will increase the gear running resistance and power consumption. Excessive pressure will damage the oil seal and the joint gasket, resulting in oil leakage.
2. Oil leaks from the joint surface of the half shaft guide and the gearbox body, mainly because the paper pad is damaged and the bolts or nuts are loose. The paper pad should be replaced and the bolts and nuts tightened.
3. The vent hole of the axle housing is blocked, the temperature rises during driving, the pressure increases, and the oil is squeezed out, resulting in oil leakage.
4. The outer end of the half shaft conduit is equipped with a skeleton oil seal, and the oil seal lip is inward and the direction is towards the gearbox body. If the installation is reversed or the oil seal is aged and cracked in application, the ring spring is too loose, broken or fallen off; the gasket is damaged or the fastening bolts and nuts are loose, the oil plug is loose or the casing is broken, all of which will cause oil leakage. If oil leakage is found at the outer end of the half shaft conduit, the oil seal should be checked as soon as possible and replaced if necessary.
5. The gear oil is not clean. Due to improper storage, transportation and storage of oil, there are molding sand, residues or metal scraps inside the rear axle housing; Shaft oil seal leaks oil. Therefore, the relevant parts must be fully cleaned before installation and use, and the applied gear oil must be clean.
