Analysis of Power Performance and Fuel Economy of Loader with Torque Converter Lock-Up Technology

In order to study the influence of torque converter lock-up technology on loader power performance and fuel economy, the power performance and fuel economy of a certain type loader with lock-up clutch was calculated and compared with the same type loader without lock-up clutch. The results show that the accumulation of maximum output power of all gears of loader increased by 31.7% after equipping lock-up clutch, the maximum speeds of different gears are increased and the corresponding kinetic 100 km fuel consumptions are decreased. It illustrates that the torque converter lock-up technology can remarkably promote the power performance at high speed, the fuel economy and the working efficiency of loader.
