Abstract
EVs will play a very significant role in meeting the challenges of global warming and depletion of oil resources. Optimizing for better efficiency without compromising on NVH performance is very challenging for electric drivelines than conventional engines. This paper discusses on the methodology to optimize the efficiency and improve NVH of gearbox for commercial vehicle application. Gears are designed and optimised for high contact ratio, high mesh efficiency, low transmission error and less load distribution factor, whereas Casing internal geometry optimised for effective lubrication and to reduce the oil churning losses.
