Design and experiment of electro-hydraulic control shift transmission for harvesting machinery
摘要
Abstract
The problems of obvious shift shock,frequent operation,and high labor intensity for drivers exist in traditional mechanical shift transmissions during harvesting operations,making it difficult for them to meet the requirements of modern agricultural operations with high efficiency and high reliability.A fast,smooth,and intelligent shifting process was achieved by the electro-hydraulic control shift transmission through the organic integration of mechanical transmission systems,hydraulic actuators,and electronic control units,which significantly improved the comprehensive working performance of harvesting machinery.Taking medium and large combine harvesters as the research object,a set of electro-hydraulic control shift transmission systems was designed,and the design schemes of its mechanical structure,hydraulic control circuit,and electronic control unit were elaborated in detail.Through bench tests and field operation verification,the system was superior to the traditional mechanical transmission structure in terms of shift time,smoothness,transmission efficiency,and operational convenience,which verified the feasibility and performance advantages of the application of electro-hydraulic control technology in the transmission system of harvesting machinery.The research results provide a theoretical basis and practical reference for the technical upgrading of the transmission system of harvesting machinery.关键词
