Execution of Nonstop Mutable Transmission Structure (NMTS) in Farming Vehicle

Abstract

This paper briefly reviews the potential use of the Continuously Variable Transmission System (CVT) and its different types in a tractor. CVT is a system in which transmission is adapted automatically through continuous variable adjustment of the pulleys. The paper starts with studying the requirement of innovation in agricultural tractors through a case study and goes about discussing the results of modeling, simulation and experimental works done in this field. The paper also focuses on advantages and disadvantages of opting CVT over other transmission systems. Different efforts performed to optimize the electronic controller were also discussed. The key results that were noticed were that CVT reduces the overall fuel consumption and weight of the system. It was also noticed that it causes vehicle to show signs of improvement footing attributes, stay away from flameout, and retain vibrations and it wipes out move stun and offers smooth increasing speed. Few instances were observed where CVT implementation cannot be a commercially viable option, but overall it seems to be a very promising technology and already many heavy vehicles have started to use them. This paper also reviews all the essential factors involved in design of a transmission system for a commercial tractor which might ease the process of collecting data.
