In this paper, the models for different power loss sources in transmissions from literature are applied and compared, which form the two methods - ISO 14179-2 and the joint model to estimate the power losses in a transmission. A 2-speed transmission in an electric vehicle is used as a case study to compare the two methods and validate them with experimental data.
Key technical drivers which can be addressed by advanced PM manufacturing technologies are, for example, the need for system downsizing in transmissions and differentials, the need for developing systems with higher power density and the strong NVH (Noise Vibration Harshness) requirements - especially for electrified transmissions or e-axle solutions.
In the late 1940s, the U.S. auto industry started an exciting experiment and spent
decades on it. One result came in '63, when the Turbine was introduced by Chrysler Corp., now a part of Fiat Chrysler Automobiles (FCA). In appearance, the two-door,
four-passenger car looked like a regular car, but it wasn't. Under its sleek shell, the car had a jet engine.
