The invention belongs to the technical field of automobile intermediate axle inter-axle differential assemblies, and discloses an inter-axle differential mechanism, an intermediate axle inter-axle differential assembly and a vehicle. The vehicle comprises the intermediate axle inter-axle differential assembly, the intermediate axle inter-axle differential assembly comprises the inter-axle differential mechanism, the inter-axle differential mechanism comprises a cross axle, a planetary gear and a differential shell, the cross axle comprises a body and a gear shaft, and the planetary gear is arranged in the differential shell. The gear shaft is fixedly arranged on the periphery of the body, and the central axis of the gear shaft is perpendicular to the central axis of the body. The planetary gear rotationally sleeves the periphery of the gear shaft; a first oil passing hole communicated with the second cavity of the speed reduction shell is formed in the side wall of the first cavity of the differential shell, a first oil passing channel is formed between the planetary gear and the cross shaft, the first oil passing channel is communicated with the first oil passing hole, a second oil passing channel is formed between the planetary gear and the differential shell, and the second oil passing channel is communicated with the first oil passing hole. Dry grinding between the planetary gear and the cross shaft and between the planetary gear and the differential shell can be avoided.

    本发明属于汽车中桥轴间差速总成技术领域,公开一种轴间差速器、中桥轴间差速总成及车辆,该车辆包括中桥轴间差速总成,中桥轴间差速总成包括轴间差速器,轴间差速器包括十字轴、行星齿轮及差速壳体,十字轴包括本体和齿轮轴,齿轮轴固定设置于本体的外周,齿轮轴的中心轴线垂直于本体的中心轴线;行星齿轮转动套设于齿轮轴的外周;差速壳体的第一腔体的侧壁开设有与减速壳体的第二腔体接通的第一过油孔,行星齿轮与十字轴之间形成第一过油通道,第一过油通道与第一过油孔接通,行星齿轮与差速壳体之间形成第二过油通道,第二过油通道与第一过油孔接通。本发明能够避免行星齿轮与十字轴之间以及行星齿轮与差速壳体之间出现干磨。
