The embodiment of the invention provides a through axle speed reducer and inter-axle differential assembly which comprises a first transmission assembly, a second transmission assembly and a sliding gear sleeve. The first transmission assembly comprises a driving shaft, a gear ring seat rotationally connected with the driving shaft, a gear ring fixedly connected with the gear ring seat, a driving cylindrical gear arranged on the outer side of the gear ring seat, a planet wheel unit meshed with the gear ring and an output gear meshed with the planet wheel unit, and the output gear is connected with a rear axle assembly. And the second transmission component is meshed with the driving cylindrical gear and is connected with the intermediate axle assembly. The sliding gear sleeve is connected with the driving shaft and can move relative to the driving shaft, the sliding gear sleeve has three positions, and when the sliding gear sleeve is located at any position, the sliding gear sleeve synchronously rotates with at least two of the driving shaft, the driving cylindrical gear and the gear ring seat, so that power transmitted to the rear axle assembly and the middle axle assembly is changed, and switching of three gears is achieved; the structure is simple and cost is low.

    本发明一实施例提供一种贯通桥减速器及轴间差速器总成,其包括第一传动组件、第二传动组件及滑动齿套,所述第一传动组件包括主动轴、与所述主动轴转动连接的齿圈座、与所述齿圈座固定连接的齿圈、设置在所述齿圈座外侧的主动圆柱齿轮、与所述齿圈啮合的行星轮单元及与所述行星轮单元啮合的输出齿轮,所述输出齿轮与后桥总成连接。所述第二传动组件与所述主动圆柱齿轮啮合,并与中桥总成连接。滑动齿套与主动轴连接并能够相对所述主动轴移动,所述滑动齿套具有三个位置,滑动齿套处于任一位置时,其与主动轴、主动圆柱齿轮及齿圈座中的至少两个同步转动,从而改变传输至后桥总成和中桥总成的动力,实现三个档位的切换,结构简单、成本低。
