Abstract

Abstract: The chassis technology of agricultural machinery is the key technology of intelligent agricultural machinery and equipment， and also the key technology that affects agricultural and rural modernization. The inherent advantages of European and American farm based and intensive planting scenarios， as well as strong industrial foundations， make Europe and America ahead of China in the field of intelligent agricultural machinery， the adaptability of agricultural machinery chassis in our country is poor， the degree of intelligence is insufficient， the comfort is poor， and the safety factor is low. In response to the above issues， combined with the actual situation and characteristics of China's agricultural machinery development， this paper will think and look forward to the direction of intelligent development of agricultural machinery chassis in the future from three aspects of intelligent drive， high adaptability walking and independent operation. This paper focuses on summarizing the progress of new technologies such as hydraulic lifting， power shifting， continuously variable transmission， variable wheelbase， wire controlled steering， and unmanned driving applied to agricultural machinery chassis. Combining with the actual application situation in China， the basic principles and characteristics of various systems related to agricultural machinery chassis are elaborated. Finally， based on the research progress of agricultural machinery chassis at home and abroad and the gap between domestic and foreign countries， reference is provided for future research and design of intelligent agricultural machinery chassis and modernization of agriculture and rural areas from strengthening the research and upgrading of electro‑hydraulic technology and E-CVT， promoting the landing of multi‑directional walking and wire controlled steering technology， and realizing intelligent control and unmanned operation.
