The invention relates to the technical field of double-axle sanitation vehicle chassis, and discloses a chassis structureof an electric rear double-axle sanitation vehicle. The chassis structure comprises a chassis, and rear axle connecting blocks are fixedly connected to the two sides of the rear end of the lower surface of the chassis. According to the chassis structure of the electric rear double-axle sanitation vehicle, when the load capacity of the electric sanitation vehicle is too large during operation, a long plate spring bends to lower the chassis due to the facts that the arm of force of the long plate spring is longer, the long plate spring shares a larger bearing surface, and the bending effect of the long plate spring is better than that of a short plate spring; the surface of an auxiliary wheel can be attached to the ground when the vehicle body sinks due to the facts that the radius of the auxiliary wheel is smaller than that of a driving wheel and the height of the lowest point of the long plate spring is the same as that of the lowest point of the short plate spring; the auxiliary wheel can support the vehicle due to the fact that the bending effect of the short plate spring is poorer than that of the long plate spring, and the contact area between the vehicle and the ground is increased; and through interaction of a cushioning spring and a telescopic rod, the vibration feeling generated by the cushioning spring can be effectively offset.

    本发明涉及双桥环卫车底盘技术领域,且公开了一种电动后双桥环卫车底盘结构,包括底盘,所述底盘的下表面后端两侧均固定连接有后桥连接块。该种电动后双桥环卫车底盘结构,当电动环卫车在进行作业其载荷量过大时,由于长板簧的长度较大力臂较长,长板簧分担的载重面较大,因此弯曲效果比短板簧更佳,此时长板簧会出现弯曲使得车辆的底盘高度下降,辅助轮的半径小于驱动轮的半径,且长板簧最低点的高度与短板簧最低点的高度相同,车身下沉时辅助轮表面将会与地面贴合,由于短板簧的弯曲效果比长板簧差,辅助轮能够对车辆进行支撑,增大了车辆与地面的接触面积,通过缓震弹簧和伸缩杆的相互作用,能够有效的抵消其产生的震动感。
