Tractors Tractor Engines and Transmission

Abstract:

As tractor drives, stage V diesel engines today differ mainly regarding exhaust gas recirculation. Fuel cells are still of interest as an alternative. A new tractor book was published at the end of 2019 and contains development fundamentals and examples for the entire powertrain.

Electric drives are becoming more and more popular, one reason is their very good efficiency level, as shown in examples of efficiency maps in this review. At Agritechnica 2019, John Deere presented an electric-mechanical power split drive transmission with high-speed electric units, which is announced for production in 2021. The special feature: Electrical power is available for implements up to 100 kW from the 700 V intermediate circuit.

Model-based methods are now suitable for calculating entire machines in virtual environments using multi-domain simulations – including NVH investigations.
