AGV driving unit with damping mechanism and steering angle detection function

Abstract

The invention relates to an AGV driving unit with a damping mechanism and a steering angle detection function. The AGV driving unit comprises a bogie assembly, the bogie assembly comprises a bottom plate, and a differential driving device is arranged at the bottom of the bottom plate; magnetic navigation sensor assemblies are arranged at the front part and the rear part of the bottom plate; a slewing bearing assembly is arranged in the center of the upper surface of the bottom plate; the slewing bearing assembly comprises a slewing stand column; a gear disc sleeves the slewing stand column; aloose-leaf plate is rotationally connected to the upper surface of the slewing stand column; a compression spring and a spring pressing plate are installed on the hinge plate, a transverse shaft is fixedly connected to the rear portion of the hinge plate, mounted bearings are installed at the two ends of the transverse shaft respectively, the mounted bearings and the spring pressing plate are connected with an AGV body together, an angle sensor is further arranged on the hinge plate, and a detection gear is installed at the position, corresponding to the angle sensor, of the bottom of the hinge plate. The AGV driving unit is simple and compact in structure, convenient to maintain, capable of adapting to severe road conditions, high in transmission precision and higher in speed.

Description

technical field [0001] The invention relates to the technical field of automated logistics equipment, in particular to an AGV drive unit with a shock absorbing mechanism and a steering angle detection function. Background technique [0002] In industries such as automobiles, logistics, home appliances, and light industry, more and more handling-type AGVs are used for automated production. Since many old factory buildings planned in the past did not consider the automatic delivery of materials, these places often have narrow logistics channels and line edges. The space is small. In order to apply the AGV to these occasions, the AGV needs to have functions such as forward, backward, and lateral movement. [0003] However, the current drive unit on the traditional AGV trolley has the following problems: ① The driving wheel is generally driven by a chain, and the chain is easy to be stretched, its service life is short, the transmission accuracy is low, and its speed is generall...

AI Technical Summary

Problems solved by technology

[0003] However, the current drive unit on the traditional AGV trolley has the following problems: ① The driving wheel is generally driven by a chain, and the chain is easy to be stretched, its service life is short, the transmission accuracy is low, and its speed is generally less than 1m / s; The rotation angle of the body is less than ±90°, and there is no angle detection function. The AGV using this drive unit can only move forward and backward, and cannot move laterally; ③The damping mechanism of the drive unit can only float in the vertical direction generally, and cannot circle The center line of the car body swings, and on bad roads, there will also be problems such as AGV off-line due to unilateral drive wheel slippage
