The invention relates to a hub reduction gear, a rear axle assembly and a vehicle. The hub reduction gear comprises a shell, a half shaft, a sun wheel, a planet carrier, a plurality of planet wheel shafts, a first planet wheel set and a second planet wheel set. The sun gear comprises a first section and a second section connected with the first section, first gear teeth are arranged on the peripheral surface of the first section, and second gear teeth are arranged on the peripheral surface of the second section; all the planet wheel shafts are arranged at intervals in the circumferential direction of the sun wheel; the first planet gear set comprises a plurality of first planet gears meshed with the first gear teeth, and the second planet gear set comprises a plurality of second planet gears meshed with the second gear teeth. According to the hub reduction gear, the first gear teeth and the second gear teeth are inclined gear teeth with opposite rotation directions, the first planet gear and the second planet gear are inclined gears with opposite rotation directions, and due to the fact that the overlap ratio of gear pairs of the inclined gears is high, the contact strength between the gears can be improved, and the situation of tooth collision between the gears can be improved; therefore, the reliability of the hub reduction gear can be improved.

    本申请涉及一种轮边减速器、后桥总成和车辆,轮边减速器包括:壳体、半轴、太阳轮、行星架、多个行星轮轴、第一行星轮组和第二行星轮组。太阳轮包括第一段和与第一段连接的第二段,第一段的外周面设有第一轮齿,第二段的外周面设有第二轮齿;全部行星轮轴围绕太阳轮的周向方向间隔设置;第一行星轮组包括多个与第一轮齿啮合的第一行星轮,第二行星轮组包括多个与第二轮齿啮合的第二行星轮。上述的轮边减速器,第一轮齿和第二轮齿为旋向相反的斜轮齿,第一行星轮和第二行星轮为旋向相反的斜齿轮,由于斜齿轮的齿轮副的重合度较高,能够提高齿轮之间的接触强度,也有利于改善齿轮之间出现打齿的情形,从而能够提高轮边减速器的可靠性。
