AGV (automatic guided vehicle) elastic support driving device using hub motor and AGV

Abstract

The invention discloses an AGV (automatic guided vehicle) elastic support driving device using a hub motor. The AGV elastic support driving device comprises a support fixing frame, a driving wheel bracket, a guide rod, a linear sliding bearing with a flange, a cylindrical spiral spring, the hub motor, a photoelectrical rotary encoder, an encoding small gear, and an encoding large gear, wherein the linear sliding bearing with the flange is fixedly arranged on the support fixing frame, and forms a vertical sliding pair together with the guide rod, the guide rod is fixedly connected with the driving wheel bracket through thread connection, and the cylindrical spiral spring is arranged on the lower part of the guide rod to realize elastic support; the two ends of a main shaft of the hub motor are sheathed on U-shaped grooves of the driving wheel bracket. The invention also discloses an AGV. The AGV elastic support driving device has the advantages that by adopting the elastic support, a driving wheel can compress the ground when the ground is not flat, so that the slipping and idle running are avoided, the vibration of the vehicle body is reduced, and the driving accuracy and stability are improved; the adverse factors caused by the installation of speed reducers are avoided, the running reliability is improved, the structure of the driving device is simplified, and the size of the vehicle body is further reduced.

Description

technical field [0001] The invention relates to an AGV driving device, in particular to an AGV elastically supporting driving device and an AGV trolley 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 visual, which can identify the trajectory path and identification position, run autonomously according to the preset path, and 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 f...

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 a multi-stage reducer, the present invention provides an AGV elastic support drive device and an AGV using a hub motor. For the trolley, 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; the use of hub motors as the driving wheel can make the driving device exempt from installation. Reduce the unfavorable factors brought by the reducer, simplify the driving device, improve the reliability of operation, and help to further reduce the size of the car body
