This study investigates the optimization of gear ratios for a 2-speed transmission, with a focus on enhancing performance and efficiency in diverse operating conditions. Specifically, the research addresses the need for two distinct gears: one optimized for field use and the other for road use. The goal is to improve the versatility and functionality of the transmission system, ensuring that it meets the demands of both rugged terrains and smooth highways. To achieve this, the study employed the company’s lifetime test simulation to fine-tune the gear ratios, optimizing them for the most effective power delivery. A significant aspect of the research is the exploration of the transition from a traditional combustion engine tractor, which typically requires multiple gear ratios, to an electric motor setup with only two gears. This transition is made feasible by the electric motor’s ability to deliver high torque across a broad RPM range, thereby enhancing performance while reducing the complexity of gear selection. The results of this optimization process show marked improvements in both the transmission's efficiency and its adaptability, making it highly suitable for a range of applications. This research offers valuable insights into the future of transmission design, particu-larly in the fields of agriculture and transportation, where there is a growing need for systems that are both efficient and versatile.
