Abstract

A wheel-side reduction axle provided with an oil returning groove and an oil stopping groove comprises an axle housing, a central reducer unit and a half axle, wherein the central reducer unit and the half axle are arranged in the axle housing; the central reducer unit comprises a driving gear and a driven gear; the left end of the central reducer unit is connected with a left wheel-side reducer through the half axle, and the right end of the central reducer unit is connected with a right wheel-side reducer through the half axle; the axle housing comprises an axle casing and axle tubes arranged at two ends of the axle casing; the oil returning groove is formed in an upper cover plate of the axle casing; a rear cover, connected with the axle casing, of the axle housing, is arranged at the rear end of the axle casing; the oil stopping groove is formed in the rear cover of the rear cover of the axle housing; the oil returning groove and the oil stopping groove are integrally casted and formed with the axle housing. The wheel-side reduction axle provided with the oil returning groove and the oil stopping groove has a good effect on reducing the temperature increase of wheel-side reducers, and is simple and convenient to process, and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of vehicle axles, in particular to a wheel-side reduction bridge with an oil return groove and an oil-retaining groove, which is mainly suitable for solving the problem of large temperature rise differences between left and right wheel-side reducers in the wheel-side reduction bridge. Background technique [0002] At present, during the temperature rise bench test of the wheel reduction bridge and the use of the whole vehicle, the temperature rise difference between the left and right wheel speed reducers of the wheel speed reduction bridge is relatively large, and the temperature rise of the wheel speed reducer is too high and overheated, resulting in the above-mentioned The main reason for the phenomenon is: when the gear of the central main reducer rotates, the lubricating oil is brought up and splashed into the shaft tubes on both sides of the axle housing, resulting in uneven temperature rise of the left...
