The invention provides a driving wheel suspension system of a relay sorting AGV (Automatic Guided Vehicle). The system comprises driving wheels distributed on two sides of the AGV, each driving wheel is connected with a motor speed reducer assembly, the motor speed reducer assemblies are arranged on a walking bracket weldment, suspension buffer parts are arranged at two ends of the walking bracket weldment, each suspension buffer part comprises a linear guide rail, a linear bearing is sleeved at the lower end of the linear guide rail and fixed on the AGV chassis, a compression spring is arranged at the upper end of the linear guide rail, a linear bearing mounting plate is arranged in the middle of the linear guide rail, the lower end of the compression spring abuts against the linear bearing mounting plate, the upper end of the compression spring abuts against an assembly pressing plate, the linear bearing mounting plate is fixedly connected with the walking bracket weldment, and the assembly pressing plate is fixed to the AGV body. The driving wheels can only float up and down under the cooperation of the linear bearings and the linear guide rails, and it can be guaranteed that the horizontal distance between the two driving wheels and a camera in the middle of the AGV is stable and fixed. The pre-tightening force of the springs is adjustable, and the structure stress state is good.

    本发明提供一种接力拣选AGV搬运小车的驱动轮悬挂系统,包括分布在搬运小车两侧的驱动轮,每个驱动轮连接一电机减速机组件,电机减速机组件设置在一行走支架焊件上,行走支架焊件两端设置悬挂缓冲部件,悬挂缓冲部件包括一直线导轨,直线导轨下端套有直线轴承,直线轴承固定在搬运小车底盘上,直线导轨上端设置压缩弹簧,直线导轨中部设置直线轴承安装板,压缩弹簧下端抵在直线轴承安装板上,压缩弹簧上端抵在一总成压板上,直线轴承安装板与行走支架焊件固定连接,总成压板固定在搬运小车车体上。所述驱动轮只能在直线轴承及直线导轨的配合下上下浮动,能保证两驱动轮与小车中部的摄像头之间水平距离稳定固定。弹簧预紧力可调,结构受力状态良好。
