AGV (Automatic Guided Vehicle) for multiple-wheel train heavy load mobile robot

Abstract

The invention relates to an AGV (Automatic Guided Vehicle) for a multiple-wheel train heavy load mobile robot. The AGV comprises a frame, wheels, an electric control device, a floating spring structure frame, a driving device and a steering device; the electric control device is electrically connected with the driving device and the steering device; the wheels are divided into driving wheels and supporting wheels; the driving wheels are coaxially connected with the driving device and are horizontally and lengthwise connected with the steering device; the floating spring structure frame is arranged between the wheels and the frame and is connected with a wheel assembly support; and the wheels are arranged on the wheel assembly support and have the effect of buffering and uniform loading. The AGV adopts a multi-wheel train full floating multi-drive chassis structure so that the generality of the driving wheels is increased; the structure size of the driving wheels is reduced, thereby reducing the production cost; and the AGV has good stability and meets the using requirements of heavy loading and multiple road surfaces.

Description

technical field [0001] The invention belongs to the technical field of intelligent logistics handling and delivery vehicles, and mainly relates to the improvement of a multi-wheel train heavy-duty mobile robot AGV vehicle. Background technique [0002] AGV vehicles have been used in developed countries since the 1960s and 1970s, and are now widely used in factory logistics automation, automated assembly lines and other fields. After the 1990s, our country also gradually began to have market demand, and gradually achieved rapid development. Especially in recent years, due to the reduction of labor force and the increase of cost, the demand for AGV has increased significantly, especially the work done by heavy-duty AGV is impossible or difficult to do manually, so the demand for heavy-duty AGV There is a large market space. In the past, AGV technology was mainly aimed at light load requirements. Generally, the load was less than 3 tons. AGV vehicles had 4 or 3 wheels, includ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the small number of wheels, the pressure of each wheel is large, and the requirements for the wheels and the ground are high;

[0005] 2. Due to the large load on the wheel, the wheel diameter needs to be increased, resulting in an increase in the chassis of the car body, inconvenient use, reduced stability, increased material weight, and increased cost;

[0006] 3. Due to the small number of wheels and the increased wheelbase (wheelbase), in order to maintain the rigidity of the car body, the profile of the car body is increased, resulting in a bulky car body, increased power, reduced efficacy, and increased manufacturing and operating costs
