Abstract

The invention provides a differential steering mechanism for an automatic guided vehicle, and a steering control method. A top plate is supported and installed on four corners of the top of a bottom plate through a plurality of supporting columns; the center position of the bottom plate is provided with a rotary disk; the rotary disk is symmetrically provided with a first wheel stand plate and a second wheel stand plate, wherein the first wheel stand plate and the second wheel stand plate are arranged in parallel; a wheel is supported and installed between the first wheel stand plate and the second wheel stand plate through a wheel axle; the top of the first wheel stand plate and the top of the second wheel stand plate are fixedly provided with a first gear disk through locking bolts; a first driven bevel gear is installed on one side of the wheel on the wheel axle, and a second driven bevel gear is installed on the other side of the wheel on the wheel axle; the first driven bevel gearis cooperated with a first transmission wheel train used for driving the first driven bevel gear to rotate; the second driven bevel gear is cooperated with a second transmission wheel train used fordriving the second driven bevel gear to rotate; and the first transmission wheel train and the second transmission wheel train are both installed between the top plate and the first gear disk. The steering mechanism is used for the rotation of the wheel of the AGV (Automatic Guided Vehicle), and a differential way is adopted to realize the steering of the wheel.

Description

technical field

[0001] The invention belongs to the field of transportation equipment, in particular to a differential steering mechanism and a steering control method for an automatic conveying trolley. Background technique

[0002] Most of the steering of some AGV cars now use the steering gear to drive the wheel frame of the wheel to realize the overall steering of the wheel. However, in this steering method, the friction between the wheel and the ground is relatively large, which leads to ineffective steering. The friction and wear of the wheels is relatively large, especially for occasions where multiple wheels need to cooperate with steering, the control algorithm of the controller requires relatively high stability. Contents of the invention

[0003] In order to solve the above technical problems, the present invention provides a differential steering mechanism and a steering control method for an automatic conveying trolley. The steering mechanism is used for the r...
