The invention relates to an AGV (Automatic Guided Vehicle) with driving wheel road holding force changing along with load, which comprises a vehicle body, the vehicle body is provided with a frame for placing the load and driving wheels which are arranged on two sides of the vehicle body and have independent driving, the front part and the rear part of the vehicle body are respectively provided with at least one supporting wheel, and a driving mechanism for increasing or decreasing the height of the frame is arranged in the vehicle body. The driving mechanism is provided with a transmission mechanism connected to the driving wheels on the two sides of the vehicle body, and when the driving mechanism lifts the frame, the driving mechanism drives the driving wheels on the two sides of the vehicle body to move independently through the transmission mechanism so as to change the road holding force of the driving wheels. According to the AGV with the road holding force of the driving wheels changing along with the loads, the road holding force of the driving wheels can be automatically and properly increased or decreased according to the loads, the problem that in the prior art, the road holding force is constant and cannot adapt to different loads and using environments is solved, energy saving in the no-load state and power performance guarantee in the full-load state are achieved, and the AGV is suitable for large-scale popularization and application. And the transportation of the AGV trolley is more efficient and safer.
本发明涉及一种驱动轮抓地力随负载变化的AGV小车,包括车体,车体具有一用于放置负载的框架和一设于车体两侧且具有独立驱动的驱动轮,且车体前部和后部至少各设有一支撑轮,车体内设置有用于提升或降低框架高度的驱动机构,驱动机构具有一连接于车体两侧驱动轮的传动机构,驱动机构提升框架时,驱动机构通过传动机构带动车体两侧驱动轮产生相互独立的移动,以改变驱动轮的抓地力。本发明所设计的驱动轮抓地力随负载变化的AGV小车,可以根据负载大小自动适当增加或减小驱动轮的抓地力,既解决了现有技术抓地力恒定无法适应不同负载和使用环境的问题,又实现了空载时的节能和满载时的动力性能保证,使AGV小车的运输更加高效、安全。
