Review of Research on Key Technologies for New Power Transmission Systems in Tractors
摘要
Abstract
The tractor serving as the core power equipment for achieving agricultural modernization and efficient production,has a technological development level that directly influences the efficiency,cost,and sustainability of agricultural operations.The industry is rapidly evolving toward high-end,intelligent,and green directions,with new power transmission technologies becoming the most critical and dynamic area of innovation in this transformation.A comprehensive review of the current research status of new power transmission technologies for tractors,both domestically and internationally was provided,which systematically addressed the field from three dimensions:theoretical research on new transmission systems,development of key technologies,and industrial applications.It was focused on diverse technical pathways,including power shift transmission,hydro-mechanical continuously variable transmission,pure electric drive systems,as well as diesel-electric hybrid,hydrogen hybrid,and methane hybrid power systems.It delved into the basic structure,working principles,and performance characteristics of these power transmission systems,and the development status of key technologies was analyzed by examining typical tractor products from China and other countries,along with their practical application outcomes and productization paths.The critical bottleneck issues that needed to be overcome in current new power transmission technologies were generalized and summarized,primarily including battery capacity and charging rates,control precision and stability,environmental adaptability of electric drive systems,multi-energy source management,and the production and storage of new energy sources.Finally,it outlined future development trends for new power transmission systems in tractors,proposing deep integration in three major directions:global energy efficiency utilization,full-scenario self-adaptive compatibility,and modular multi-functional expansion.关键词
