The drive axle hub reduction gear comprises a mounting disc, a hub, an inner gear ring, a planet carrier, a driven shaft and a shell, the inner gear ring and the shell are fixed to the two opposite sides of the mounting disc respectively, and the inner gear ring is located in the hub; the hub is connected with the mounting disc through a bearing, the planet carrier is fixed on the hub, and a planet wheel is arranged on the planet carrier; one end of the driven shaft extends into the inner gear ring and is provided with a sun gear, and the sun gear and the inner gear ring are both meshed with the planet gear; the other end of the driven shaft penetrates through the mounting disc and is provided with a first driven wheel, a first driving wheel is arranged in the shell, and the first driving wheel is meshed with the first driven wheel. According to the power transmission device, power is transmitted to the hub through the driven shaft, the sun gear, the planet gears and other components, and power transmission is achieved; the hub is separated from the driving shaft, so that axial movement is avoided; and the bearing capacity and the reliability of the drive axle are improved.

    本发明提供了一种驱动桥轮边减速器,包括安装盘、轮毂、内齿圈、行星架、被动轴、壳体,所述内齿圈与壳体分别固定于安装盘的相对两侧,内齿圈位于轮毂内;所述轮毂与安装盘通过轴承连接,所述行星架固定于轮毂上,行星架上设有行星轮;所述被动轴的一端伸入内齿圈内并设有太阳轮,太阳轮以及内齿圈均与所述行星轮啮合;被动轴的另一端贯穿安装盘并设有第一被动轮,所述壳体内设有第一主动轮,第一主动轮与第一被动轮啮合。采用本发明,通过被动轴、太阳轮、行星轮等构件将动力传递至轮毂上,实现动力传递;轮毂与驱动轴分离,避免了轴向窜动;提高了驱动桥的承载能力和可靠性。
