Problems solved by technology

At present, the suspension system commonly used by AGV is a passive spring for shock absorption, which cannot realize the adjustment of the equivalent elastic coefficient. When the trolley carries light cargo, the spring compression is small. At this time, the suspension system is elastic and prone to frequent trolley Jumping phenomenon; when the trolley carries heavy goods, the spring compression is relatively large, and the suspension system is relatively soft at this time. When encountering uneven ground, the trolley vibrates greatly up and down

Embodiment Construction

[0034] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0035] The purpose of the present invention is to provide an electronically controlled elastic unit with adjustable spring combination stiffness, which can make the AGV suspension system elastically adjustable to adapt to different road conditions, and has the characteristics of wide elastic adjustment range and strong real-time performance. At present, the suspension system commonly used by AGV is a passive spring damping, which cannot be adjusted elastically. If a parallel structure of multiple springs is used, and each spring can independently control its compression to form an elastic unit system, the elastic unit system composed of multiple springs working together has the biggest advantage that the equivalent elastic coefficient can be adjusted, and the spring The more, the greater the adjustable range...

Abstract

The invention discloses an AGV suspension elastic adjustment method and system. The AGV suspension elastic adjustment method is characterized by comprising a plurality of elastic adjustable lead screwelastic units installed on wheel bottom plates of an AGV. The lead screw elastic units comprise motors, couplings, lead screws, sliding blocks and springs, the upper ends of the springs are hung on the sliding block, and the lower ends of the springs are connected with the wheel bottom plate. The motors drives the lead screws through the couplings to control the sliding blocks up and down, and the expansion and contraction quantity of the springs can be adjusted. The AGV suspension elastic adjustment method and system adapts to different road conditions through flexible adjustment of an AGV suspension system, and has the characteristics of being wide in elastic adjustment range, high in real-time performance and the like.

Description

technical field [0001] The invention relates to the field of AGV technology, in particular to an elastic adjustment method and system of an AGV suspension system. Background technique [0002] AGV is the abbreviation of (Automated Guided Vehicle), which means "automatically guided transport vehicle". With the rise of AGV technology, the requirements for the stability of AGV cars are getting higher and higher, and shock absorption performance is the basic requirement of AGV cars. At present, the suspension system commonly used by AGV is a passive spring for shock absorption, which cannot realize the adjustment of the equivalent elastic coefficient. When the trolley carries light cargo, the spring compression is small. At this time, the suspension system is elastic and prone to frequent trolley Jumping phenomenon; when the trolley carries heavy goods, the spring compression is relatively large, and the suspension system is relatively soft at this time, and the trolley vibrates...
