A Study on the Velocity Ratio Control of the Tractor Continuously Variable Transmission
The speed ratio regulation law is one of the main bases in the matter of the continuously variable transmission control;it is also the foundation for bringing into play the superior transmission function of the continuously variable transmission.Based on the study of the working procedure of the engine,this paper elaborates the optimal fuel economy and the optimal power performance work curve of the engine.In accordance with the working features of agricultural tractors, a speed ratio regulation law on the optimal fuel economy and the optimal power performance is formulated concerning the continuously variable transmission of agricultural tractors; meanwhile the controller of velocity ratio is also engineered and has undergone experimental verification by way of simulation mode.
