AGV with a new driving structure

Abstract

An AGV with a novel driving structure comprises a chassis and a driving structure arranged on both sides of the chassis. The driving structure comprises a mounting bracket, a swinging bracket, a driving mechanism and a driving device. The driving device is used for driving the AGV to travel. A swing bracket is provide with two, The two swing brackets are respectively articulated with the two endsof the mounting bracket and connected with each other through a synchronous structure. The two swing brackets are respectively provided with driving devices, which are used for driving one of the swing brackets to rotate relative to the mounting bracket, and the other swing bracket to rotate in the synchronous reverse direction through the driving of the synchronous structure. In accordance with that prior art, The AGV of the invention has a novel driving structure and adopts the mode of the driving mechanism cooperating with the synchronous structure to control the driving wheels on both sides of the AGV to realize synchronous reverse rotation in the symmetrical direction, so that the AGV not only has the functions of straight moving and transverse moving, but also can realize in-situ rotation and low-height lifting, and has simple structure and low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of operation and transportation, and in particular relates to an AGV with a novel driving structure. Background technique [0002] The traditional AGV differential drive structure usually has a driving wheel on the left and right sides fixedly installed on the chassis. Although the structure is simple, because the mounting bracket of the driving wheel is fixed on the chassis, its drive can only move forward and backward in one direction. It is impossible to have the functions of straight travel and lateral movement at the same time. Therefore, AGVs that currently require lateral movement can only be realized by using double steering wheels with universal wheels or a structure of four mecanum wheels. However, using four mecanum wheels The cost and maintenance cost of the wheel drive is the highest, followed by the double rudder wheel drive, and the rudder wheel integrates the steering gear and the drive wheel...

[0002] The traditional AGV differential drive structure usually has a driving wheel on the left and right sides fixedly installed on the chassis. Although the structure is simple, because the mounting bracket of the driving wheel is fixed on the chassis, its drive can only move forward and backward in one direction. It is impossible to have the functions of straight travel and lateral movement at the same time. Therefore, AGVs that currently require lateral movement can only be realized by using double steering wheels with universal wheels or a structure of four mecanum wheels. However, using four mecanum wheels The cost and maintenance cost of the wheel drive is the highest, followed by the double rudder wheel drive, and the rudder wheel integrates the steering gear and the drive wheel, making its overall height higher, and the AGV driven by the rudder wheel cannot achieve low-height lifting. liter, causing inconvenience to users in the AGV industry
