AGV steering wheel drive system module

Abstract

The invention relates to the technical field of guide transport equipment and discloses an AGV steering wheel drive system module. The AGV steering wheel drive system module comprises a drive unit, a speed feedback unit, a transmission unit, an angle feedback unit and a drive wheel. The drive unit, the speed feedback unit and the angle feedback unit are all arranged on an installation board. One end of the drive unit is connected with the speed feedback unit through a chain wheel mechanism. The speed feedback unit is connected with the transmission unit through a linkage shaft on the connected chain wheel mechanism. The transmission unit is connected with the drive wheel. The linkage shaft is provided with a steering mechanism connected with the angle feedback unit. By the adoption of the AGV steering wheel drive system module, drive power transmission efficiency is high, the accuracy of signals fed back through an encoder and an angle sensor is high, the space occupied by drive steering operation is small, machining cost is low, and installation and maintenance are easy.

Description

technical field [0001] The invention relates to the technical field of guiding transportation equipment, in particular to an AGV steering wheel drive system module that realizes equipment function control through signal feedback such as speed and angle steering changes. Background technique [0002] AGV is the abbreviation of (Automated Guided Vehicle), which means "automatically guided transport vehicle". AGV belongs to the category of WMR—Wheeled Mobile Robot. [0003] A truck that does not require a driver in industrial applications uses a rechargeable battery as 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 AGV moves according to the information brought by the electromagnetic track. with action. [0004] AGV is characterized by wheeled movement. Compared with wal...

Problems solved by technology

[0005] At present, the structure of the steering wheel drive unit module in the AGV industry adopts the way that the driving power motor is directly connected to the driving wheel, so that the steering of the driving wheel takes up a large space, and the overall size of the AGV cannot be made small. Secondly, the force on the motor shaft is relatively large. Serious, easy to damage the motor, making the life of the drive module shorter

The steering drive module adopts gear meshing transmission, which requires high machining accuracy of the gears. The longer the two gears are meshed, the more serious the wear of the gears will be, resulting in lower transmission accuracy, and the deviation of the feedback signal of the steering angle sensor is larger. Affect the stability of the steering wheel drive unit, making the AGV swing unstable during driving
