The invention relates to an inter-axle differential mechanism. A driving gear assembly comprises a driving gear shaft and a driving gear arranged on the driving gear shaft in a sleeving mode in the first direction. The driven gear assembly comprises a driven gear shaft coaxial with the driving gear shaft and a driven gear arranged on the side, facing the driving gear, of the driven gear shaft. The gear sleeve assembly comprises a fixed gear sleeve and a sliding gear sleeve which are arranged in the first containing cavity, the fixed gear sleeve is connected to the driving gear shaft in the first direction, and the sliding gear sleeve is slidably connected to the driven gear shaft in the first direction. According to the through axle speed reducer assembly, the fixed gear sleeve and the sliding gear sleeve in the inter-axle differential are arranged in the first containing cavity formed by the driving gear shaft and the driven gear shaft, the space in the driven gear shaft is reasonably utilized, the fixed gear sleeve and the sliding gear sleeve do not occupy the axial space independently any more, and therefore the axial size of the through axle speed reducer assembly is reduced, and the service life of the through axle speed reducer assembly is prolonged. And the overall structure of the device is more compact, and meanwhile, an available arrangement space is provided for upgrading and reconstruction of a lubricating structure.

    本申请涉及一种轴间差速器,主动齿轮组件包括主动齿轮轴以及沿第一方向套设于主动齿轮轴的主动齿轮;从动齿轮组件包括与主动齿轮轴同轴设置的从动齿轮轴以及设于从动齿轮轴朝向主动齿轮一侧的从动齿轮;齿套组件包括设于第一容纳腔的固定齿套和滑动齿套,固定齿套沿第一方向连接于主动齿轮轴,滑动齿套沿第一方向滑动连接于从动齿轮轴。本申请通过将轴间差速器中的固定齿套和滑动齿套设置在主动齿轮轴与从动齿轮轴所形成的第一容纳腔,合理利用了从动齿轮轴内的空间,固定齿套和滑动齿套不再单独占用轴向空间,从而减小了贯通桥减速器总成的轴向尺寸,使得装置的整体结构更为紧凑,同时也为润滑结构的升级改造提供了可供使用的布置空间。
