Electro-hydraulic Wet Clutch Transmission System for Agricultural Tractors
In recent and emerging technological developments, powertrain were mostly accompanied with electronics for efficient and precise control of powertrain system. Agricultural tractors are of no exception to this context. Most of the higher horsepower tractors above 50 HP are equipped with modern transmission systems such as Power-shuttle, Power-shift etc., having their wet clutch transmis- sion and diesel engine controlled by an Electronic Control Unit. This is possible only with an engine that receives and provides electronic signals. Whereas a tractor with mechanical engine is of predominant use in the Indian farm lands due to their low cost and immediate availability compared to that of an engine equipped with advanced/modern electronics. Hence, there is a demand for low cost powertrain with improved controls and without engine electronics. This research work depicts on one such development, Power Shuttle Transmission and Controls for agricultural tractor with a mechanically operated engine. This research work also address the safety features for protecting and increasing the life of system components like clutch slippage, energy dissipation, power consumption. Few system protection was al- so done through fault mode diagnosis via safety features such as anti-stalling, overrun cut off shuttling, wrong direction detection, etc. with minimal sensors and powertrain components.
