Summary:

Energy savings in automotive applications has always remain an important aspect of research. In addition, today's highspeed requirements in electric vehicles require high-efficiency drivelines to match overall vehicle mileage or range.This paper presents the validation of the overall efficiency and drag losses of the highspeed Driveline for an ATV with 4-Wheel Drive System.The efficiency and drag losses were measured in the powertrain testbed where the test units were placed between two Transient Dynamometers. The main aim of the test was to validate the overall efficiency as a function of input speed and torque. All these measured values of the gearbox efficiency are included in various graphs.The tests were performed for complete functional range of test unit at max operating oil temperatures for Transmission and Front Differential testing. Drive shafts tests were performed at its complete range and various inclination angle up to max failure point.The wheel hub was tested at various radial loading on bearings in different surrounding temperature maintained by a closed chamber.This paper will give us the actual losses (%) which can be referred during the initial designing phase, advanced simulations, and other electric vehicle design to minimize losses and optimize the performance of drivelines
