Heavy-load universal wheel

Abstract

The invention provides a heavy-load universal wheel, which is characterized in that a wheel carrier is made of a high-strength structural steel material; a wheel shaft is horizontally and fixedly mounted on the wheel carrier; wheels are rotationally connected with the wheel shaft through bearings; a rotating shaft is vertically mounted on the wheel carrier; an inner ring of a plane thrust bearingis connected with the rotating shaft; the outer ring of the plane thrust bearing is fixedly connected to the wheel carrier; the periphery of the rotating shaft is sleeved with a cushion; a cushion lower baffle is mounted on the wheel carrier; the cushion lower baffle is located at the lower end of the cushion; a cushion upper baffle is mounted on the wheel carrier, and the cushion upper baffle islocated at the upper end of the cushion. The difference between the universal wheel and other universal wheels is that the universal wheel is large in riding load, large in eccentric distance, capableof achieving the buffering function and the like, the advantages of being uniform in wheel pressure, small in steering resistance and the like are guaranteed when multiple wheels are used at the sametime, and the universal wheel is a preferred product of a multi-spool heavy-load AGV.

Description

technical field [0001] The invention relates to the technical field of universal wheels, in particular to a heavy-duty universal wheel. Background technique [0002] AGV trolley refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, with safety protection and various transfer functions, and a transport vehicle that does not require a driver in industrial applications. The battery is its power source. Generally, the computer can be used to control its travel route and behavior, or use the electromagnetic track (electromagnetic path-following system) to set up its travel route. The electromagnetic track is pasted on the floor, and the unmanned van relies on the information brought by the electromagnetic track. For movement and action, the AVG car needs to use universal wheels to improve the moving and steering effect of the car during operation. The existing universal wheel...

Generally, the computer can be used to control its travel route and behavior, or use the electromagnetic track (electromagnetic path-following system) to set up its travel route. The electromagnetic track is pasted on the floor, and the unmanned van relies on the information brought by the electromagnetic track. For movement and action, the AVG car needs to use universal wheels to improve the moving and steering effect of the car during operation. The existing universal wheels have a small bearing capacity and eccentricity, and the universal wheels do not have the function of buffering, causing the AVG car to run Shaking occurs during the process, and the uneven wheel pressure of the universal wheel is likely to cause the wheel to fail, and the resistance is too large during the operation of the trolley
