The invention relates to a truck axle bearing oil seal structure. The truck axle bearing oil seal structure comprises a hub inner bearing and an oil seal, the hub inner bearing comprises a hub inner bearing inner ring and a hub inner bearing outer ring, the hub inner bearing inner ring is fixedly installed on an axle housing, a rear extending part is arranged at the inner end of the hub inner bearing inner ring, and the oil seal is installed on the rear extending part. According to the bearing oil seal structure, the rear extending part is arranged on the hub bearing inner ring, and the rear extending part is arranged to serve as an oil seal base and a part of a combined oil seal, so that an inner ring of the combined oil seal is omitted, and installation is easier and more convenient. A disc-shaped part perpendicular to the axial direction can abut against the oil seal in a hub, so that the disc-shaped part cannot move in the radial direction and can also be matched with the oil sealin the hub, so that the sealing effect is better, and an blocking part is added for a labyrinth flow channel for oil leakage.
Description
technical field [0001] The invention relates to the technical field of truck manufacturing, in particular to a bearing oil seal structure. Background technique [0002] Oil seals are generally used to seal lubricating oil on the shaft. The function of the oil seal is to isolate the oil chamber from the outside world, which not only prevents the lubricating oil in the oil chamber from leaking out but also prevents dust from entering and causing the shaft to be damaged by friction. [0003] Such as figure 1 As shown, the bearing oil seal structure in the prior art generally includes two parts, the first ring 21 and the second ring 22, the second ring 22 is fixed on the axle housing 2, and the cross section of the second ring 22 has an "L" shape on one side. , which includes an integrally formed cylindrical sleeve 221 and a sleeve plate 222, the sleeve 221 is fixedly overlaid on the axle housing 2; the first ring 21 is fixed with the hub 1 and rotates through the hub 1 togethe...
