The invention discloses a rear axle structure of an electric cleaning vehicle. The rear axle structure comprises a shell, a cushioning mechanism, a main shaft and a motor; the shell is a hollow cylinder with two open ends, a through groove communicated with the interior is formed in the upper end of the middle of the outer ring face of the shell, a protective shell is fixedly installed in the middle of the outer ring face of the shell, the interior of the protective shell is hollow, and a partition plate is fixedly installed in the middle of the interior of the protective shell. The protective shell for sealing a transmission mechanism is provided, and the situation that dust or sundries enter the transmission mechanism, and the transmission mechanism is damaged or the transmission efficiency is reduced can be prevented, and meanwhile, personnel can be prevented from directly contacting the transmission mechanism; the rear axle of the electric cleaning vehicle is in a bilateral power mode, and the problems of unbalanced power transmission and unstable running during running of the whole vehicle are solved; and simple cushioning mechanisms are arranged at the two ends of the rear axle, so that the use comfort of the electric vehicle is improved under the condition of considering the manufacturing cost.
本发明公开了一种电动保洁车的后桥结构,包括外壳、缓震机构、主轴和电机;外壳:所述外壳为两端开放的中空圆筒,且外壳的外环面中部上端开设有与内部相连通的通槽,外壳的外环面中部固定安装有保护壳,所述保护壳的内部为中空,且保护壳的内部中部固定安装有隔板,设置有密封传动机构用的保护壳,能够避免传动机构内进入灰尘或杂物,导致传动结构受损或者传动效率降低,同时能够避免人员直接接触传动机构,电动保洁车的后桥为双侧动力模式,避免出现整个车辆的运行时动力传动不平衡,行驶不平稳的问题,且后桥两端设置有简易缓震机构,在考虑造价的情况下提升电动车使用时的舒适性。
