Problems solved by technology

[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 with multiple wheels that need to cooperate with steering, the stability requirements for the control algorithm of the controller are relatively high

Embodiment 1

[0029] see Figure 1-4 , the differential steering mechanism of the automatic conveying trolley, which includes a base plate 13, the top four corners of the base plate 13 are supported and installed with a top plate 4 by a plurality of support columns 27, a rotating disc 18 is installed at the center of the base plate 13, and the rotating disc 18 is installed at the center of the base plate 13. A first wheel frame plate 17 and a second wheel frame plate 10 arranged in parallel are symmetrically installed on the disc 18, and a wheel 15 is supported and installed between the first wheel frame plate 17 and the second wheel frame plate 10 by a wheel shaft 29. The first wheel frame plate 17 and the top of the second wheel frame plate 10 are fixedly installed with the first gear plate 9 by locking bolts, and the first driven bevel gear 16 is installed on the wheel shaft 29 and on one side of the wheel 15, On its other side, the second driven bevel gear 14 is installed, and the first...

Embodiment 2

[0038] The steering control method of the differential steering mechanism of any one of the automatic conveying trolleys, when turning is required, by controlling the rotating speeds of the first motor 28 and the second motor 1 to cause a speed difference, the rotation of the first motor 28 The first gear 26 will be driven, and then the second gear 25 will be driven by the first gear 26, and the second gear 25 will drive the central shaft 2, and the third gear 20 will be synchronously driven by the central shaft 2, and then the third gear 20 will drive the fourth gear. The gear 21 drives the first vertical shaft 23 through the fourth gear 21, and then the first driving bevel gear 19 is driven by the first vertical shaft 23, and the first driving bevel gear 19 is meshed with the first driven bevel gear 16 to drive the wheels 15 The inner axle 29 rotates at a speed A;

[0039] The rotation of the second motor 1 will drive the fifth gear 5, then the fifth gear 5 drives the sixth ...

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...
