Driving unit of AGV (Automatic Guided Vehicle) and AGV

Abstract

The invention belongs to the technical field of automatic navigation carrying vehicles, and particularly relates to an AGV driving unit and an AGV. The AGV driving unit is provided with secondary frames located on the two opposite sides of a main frame, the secondary frames are rotationally connected with the main frame, and the two opposite sides of each secondary frame are provided with a driving wheel assembly and a driven wheel assembly; the driven wheel assembly is additionally arranged between the driving wheel assembly and the main frame, downward pressure applied by loads can be shared, effective supporting is provided for the AGV frame, accordingly, the loads of the driving wheels are reduced, the service life of the driving wheels is prolonged, after the driven wheel assembly is additionally arranged, the force arm from the driving wheels to the center of the driving unit is correspondingly increased, and the driving efficiency is improved. Therefore, the wheel diameter of the driving wheel and the gyroscopic moment of the driving unit can be reduced on the basis, the cost is reduced, the distance between the frame and the bottom surface is reduced as far as possible, the gravity center of the AGV is lower, the AGV runs more stably, the flexible frame formed among the main frame, the second-stage frame and the third-stage frame can ensure that the AGV is prevented from bearing too much rigid impact, and the service life of the AGV is prolonged. And the service life of the driving unit is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automatic navigation transport vehicles, in particular to an AGV drive unit and the AGV. Background technique [0002] The existing AGV includes a frame and a plurality of differential drive units located at the bottom of the frame. The drive unit includes a main frame, two driving wheels and a motor. Cantilevers are respectively extended on both sides of the main frame. The driving wheels and the motor are located on On the cantilever, the drive wheels on both sides are driven by their respective motors to realize differential drive. When the load increases, the wheel diameter, wheel width and the size of the cantilever will increase correspondingly. As the width increases, the resistance and wear of the driving wheel during the rotation process also increase accordingly, resulting in an increase in cost. The rigid impact is large, which increases the load on the drive unit and affects its service life....
