Background

The AGV is a short-term automatic guided vehicle, and along with the increasing use of the AGV in cooperation with material automation in the industry, the requirement on the AGV is higher and higher. The most prominent is toward heavy loading. The traditional AGV chassis structure has an irreconcilable contradiction in the heavy load development. The driving force obtained by the conventional AGV driving wheel is positive pressure applied to the driving wheel by virtue of a spring on the driving wheel, and the driving friction force is generated by the driving wheel under the driving of a motor and a speed reducer. The structure can meet the use condition under light load, but shows the disadvantage under heavy load. Firstly, if the heavy-load AGV wants to drive smoothly, the driving wheel needs a large enough positive pressure to generate a driving friction force under the condition that the friction coefficient between the driving wheel and the ground is constant, however, the positive pressure is transmitted to the driving wheel through a spring by means of the gravity of the vehicle body, so that the weight of the vehicle body needs to be very heavy under the heavy-load condition. As the weight of the AGV load increases, the vehicle body weight needs to follow the increase. This requires a synchronous increase in the drive power of the motor.

And thus a series of increases in power supply and the like are required. In order to solve the irreconcilable contradiction, the method is provided

A novel AGV chassis structure is provided.
