摘　　要：为解决拖拉机中机械式变速箱换向操纵沉重,效率低的问题,提出一种同时具备离合器液压助力和电液控制换向功能的换向系统。该系统中离合器液压助力和液压控制换向功能相互结合,当离合器未操纵时,换向无法动作,防止误操作,保证操纵的安全性;并且通过电液控制实现操纵力的减轻,改善操纵的舒适性。In order to solve the problem of heavy control and low efficiency of mechanical transmission reversing in tractor,a reversing system with clutch hydraulic power and electro-hydraulic control simultaneously was proposed.In the system,the clutch hydraulic power and hydraulic control reversing function are combined with each other,when the clutch is not operated,the reversing cannot act,prevent disoperation,and ensure the safety of the operation;And through the electro-hydraulic control to achieve the reduction of control force,improve the comfort of control.
