AGV forklift with rear differential driving wheels

Abstract

The invention discloses an AGV forklift with rear differential driving wheels. The AGV forklift comprises a forklift body, a control circuit unit used for automatic guiding is arranged on the forklift body, two supports used for supporting the forklift body are arranged at the rear end of the forklift body in a forking mode, and a goods forking arm which can be connected with the forklift body in an up-down sliding mode to achieve lifting is arranged above the two supports; at least one chain type driving wheel assembly is contained in each support, each chain type driving wheel assembly is provided with a driving wheel used for making contact with the ground, and each chain type driving wheel assembly is independently controlled by the control circuit unit so that the driving wheels on the two supports can make differential motion; and at least one supporting wheel is further arranged at the bottom of the vehicle body and used for making contact with the ground. According to the AGV forklift, an electric forklift with the automatic guiding function can achieve rear differential driving, walking and turning are flexibly achieved, the turning radius is reduced, the balance weight of a forklift head is reduced, and meanwhile the road holding force of the driving wheels is guaranteed.

Description

technical field [0001] The invention relates to the technical field of intelligent forklifts, in particular to an AGV forklift with rear differential drive wheels. Background technique [0002] With the development of logistics and warehousing industries, electric forklifts for moving goods in warehouses are becoming more and more widely used. Configuring an automatic guidance module on an electric forklift can make it an AGV forklift. [0003] The end of the electric forklift with the forklift arm is the rear end (or rear end) of the vehicle, and the end where the electric forklift body is located is the front end (or front end) of the vehicle. [0004] The driving wheels of existing electric forklifts are generally driven by a single steering wheel, and its walking and steering are controlled by separate motors. Meanwhile, the driving wheels of current electric forklifts are generally arranged on the front part. [0005] Driving with a single steering wheel has the follo...

AI Technical Summary

Problems solved by technology

[0006] 1. Electric forklifts driven by a single steering wheel have poor walking flexibility and require a large turning radius and a long straightening distance. Generally, intelligent storage projects require a high utilization rate of the area, so the reserved channel is not Very wide, under this condition, the traditional single steering wheel electric forklift has no competitive advantage

[0007] 2. The drive motor of a single steering wheel drive forklift is equipped with one drive motor on the entire forklift. When the load is heavy, the power of a single drive motor needs to be selected with high power, and the large current generated during operation will affect the wire selection and safety control belt. Inconvenience

[0009] Because the load (goods) is placed on the rear of the forklift truck and on the forklift arm, in order to prevent the single steering wheel of the front part from tilting and ensure its grip, the front design is heavier or the counterweight is added, which will cause the forklift itself to be too heavy. heavy and increased power loss
