The invention discloses a wheel-side walking planetary reduction gear of an engineering vehicle. The planetary reduction gear is of a two-stage planetary transmission structure, one end of an input shaft is fixedly connected with a wheel-side driving motor, a brake assembly is fixedly installed between the input shaft and the wheel-side driving motor, the other end of the input shaft is fixedly connected with a first-stage sun wheel, O-shaped sealing rings are designed at a connecting position of a bearing pedestal end cover and a first-stage inner gear ring and a connecting position of the first-stage inner gear ring and a second-stage inner gear ring, and therefore, good sealing performance of the reduction gear is guaranteed; a ventilation cap is designed above a second-stage planet carrier and connected with a ventilation hole penetrating through the second-stage planet carrier, and therefore, good heat dissipation performance of the reduction gear is guaranteed; and a second-stagesun wheel is fixed to the first-stage planet carrier through a limiting block, a shaft check ring and a hole check ring, axial displacement of the second-stage sun wheel is limited, rotation frictiongenerated between the second-stage sun wheel and the first-stage sun wheel is avoided, and noises and heat are reduced to a great extent.

    本发明公开了一种工程车轮边行走行星减速装置,所述行星减速机为二级行星传动结构,所述输入轴一端固定连接有轮边驱动电机,所述输入轴与轮边驱动电机之间固定安装有刹车组件,所述输入轴另一端固定连接有一级太阳轮,轴承座端盖与一级内齿圈、一级内齿圈与二级内齿圈的联接部位均设计有O型密封圈,保证了减速机良好的密封性,二级行星架上方设计有透气帽,透气帽与二级行星架上贯穿的透气孔相连接,保证了减速机良好的散热性,所述二级太阳轮通过限位块、轴用挡圈、孔用挡圈固定在一级行星架上,限制了二级太阳轮的轴向蹿位移动,避免了二级太阳轮与一级太阳轮之间产生旋转摩擦,极大程度上减少了噪音和发热。
