Abstract

The invention provides a through type drive axle main speed reducer structure which comprises a driving cylindrical gear, a rear half axle gear and a planetary gear, a first rolling mechanism is arranged between the driving cylindrical gear and a main shaft, and a second rolling mechanism is arranged between the rear half axle gear and the main shaft. And a third rolling mechanism is arranged between the planetary gear and the cross shaft. A spline is arranged on the end face of the input flange; the end face of the main shaft is provided with a spline matched with the spline on the end face of the input flange. The through type drive axle main speed reducer effectively solves the problems that in the prior art, a through type drive axle main speed reducer is heavy in mass, low in working efficiency, short in service life, poor in reliability and the like.

Description

Technical field [0001] The invention belongs to the field of automobile manufacturing, and specifically relates to a through-type drive axle main reducer structure. Background technique [0002] Currently, in the context of limiting emissions and efficient transportation, axles need to meet technical requirements such as light weight, high efficiency, and long service life. However, in the conventional axle main reducer layout, the driving bevel gear mostly uses a riding type support. This support method has a large offset distance, high friction loss and oil churning loss, and reduces the transmission efficiency; and the traditional axle main reducer Adjustment shims are usually used on the driving bevel gear of the reducer. The main cone bearing preload is adjusted by selecting adjustment shims of different thicknesses. There are many thickness specifications of the adjustment shims, and the assembly actions are complex and easy to repeat. [0003] Conventional axle main ...
