AGV elastic support driving device with hub motor

Abstract

The invention discloses an AGV elastic support driving device with a hub motor. Linear sliding bearings with flanges are fixed to a supporting and fixing frame. The threaded ends of guiding rods penetrate the linear sliding bearings with the flanges. Cylindrical spiral springs are installed on the lower portions of the guiding rods. The guiding rods are fixed to a driving wheel support through threads. The two ends of a main shaft of the hub motor are arranged on a U-shaped groove of the driving wheel support in a sleeving mode. The stretch-out portion of the main shaft of the hub motor is sleeved with U-shaped grooves of anti-loosening pieces, and the U-shaped grooves of the anti-loosening pieces are fixed to the driving wheel support. An encoding large gear is fixed to one end of a shell of the hub motor. A photoelectric rotary encoder is fixed to the driving wheel support. An encoding small gear is fixed to a main shaft of the photoelectric rotary encoder and is meshed with the encoding large gear. By means of an elastic support, a driving wheel can compress the ground when a road surface is rough, slipping and idling are prevented, vibration of a vehicle body is reduced, and travelling accuracy and travelling stability are improved. By means of the driving device, adverse factors caused when a speed reducer is installed are avoided, and the running reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of navigation trolleys, and relates to an AGV elastic support driving device using a hub motor. Background technique [0002] AGV (Automated Guided Vehicle), that is, automatic navigation vehicle, is a kind of automatic navigation device equipped with electromagnetic, optical or vision, which can identify the trajectory path and identification position, and run autonomously according to the preset path to complete the transportation operation. Pilot automated transport equipment. [0003] AGV belongs to the category of wheeled mobile robots. Compared with other commonly used equipment for material transportation, AGV has the advantages of low cost, high work efficiency, simple structure, strong controllability, and good safety. Moreover, the path laying of AGV has high flexibility and is not limited by the site and road. Therefore, in the automated logistics system, AGV is an important automated and flexib...

Problems solved by technology

[0006] In order to overcome the shortcomings of the existing AGV drive module that cannot automatically adapt and adjust according to the ground conditions and the mechanism is too complicated and oversized with multi-stage reducers, the present invention provides an AGV elastic support drive device using a hub motor. The elastic support can make the driving wheel press the ground tightly when the road surface is uneven to prevent slipping or idling, reduce the vibration of the car body, and improve the accuracy and stability of walking; using the hub motor as the driving wheel can make the driving device exempt from installing a reducer belt. Reduce the unfavorable factors, simplify the driving device, improve the reliability of operation, and facilitate the further reduction of the car body size
