Embodiment Construction

[0012] see figure 1 , The half shaft for the drive axle includes a half shaft body 1, the spline end of the half shaft body 1 is provided with a boss 2, and the boss 2 is provided with a ring of grooves, and the groove is sleeved with an elastic retaining ring for the shaft 3. A magnet 4 is provided on the boss 2 between the elastic retaining ring 3 for the shaft and the half shaft body 1, and an aluminum sheet 5 is provided on the boss 2 between the magnet 4 and the half shaft body 1.

[0013] see figure 1 When assembling, first install the aluminum sheet 5 on the boss 2, then install the magnet 4, and then install the shaft circlip 3, after the assembly is completed, insert the half shaft into the inter-wheel differential to match the half shaft gear .

Abstract

The invention discloses a half shaft for a drive axle. The half shaft comprises a half shaft body, wherein a boss is arranged at the spline end of the half shaft body; and a magnet is arranged on the boss. According to the half shaft disclosed by the invention, the boss assembled with the magnet is added in case of ensuring the invariable torque transfer function of the half shaft, and the magnet adsorbs wear iron chippings in a differential mechanism; and the iron chippings can be eliminated only by regularly extracting the half shaft, thus reducing the abnormal wear of components in the inter-wheel differential mechanism, reducing the faults of the differential mechanism, and improving the performance of an axle assembly.

Description

[0001] Technical field [0002] The invention relates to the field of half shafts for drive axles, in particular to a half shaft for drive axles with magnets. Background technique [0003] On non-disconnected axles, the half shaft transfers torque from the half shaft gear in the inter-wheel differential to the driving wheels. Because the relative movement of the parts in the wheel differential will produce iron filings, it will cause abnormal wear of the differential shell, cross shaft, side gears, and planetary gears in the differential, which becomes one of the reasons for the sintering of the differential. The device cannot work normally, which affects the performance of the vehicle. Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a semi-shaft for a drive axle to solve the problem of abnormal wear caused by iron filings generated by the relative movement of various parts in the differential. [0005] The technical s...
