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.
本发明提供一种贯通式驱动桥主减速器结构,该减速器包括主动圆柱齿轮、后半轴齿轮和行星齿轮,所述主动圆柱齿轮与主轴之间设置有第一滚动机构,所述后半轴齿轮与所述主轴之间设置有第二滚动机构,所述行星齿轮与所述十字轴之间设置有第三滚动机构。还包括输入凸缘,所述输入凸缘端面上设有花键;所述主轴端面上设有花键与所述输入凸缘的端面花键相配合。本发明有效的解决了现有技术中贯通式驱动桥主减速器质量重、工作效率低、寿命短及可靠性差等问题。
