EV Automotive Transmission System Design
This course was designed in conjunction with and is supported by the American Bearing Manufacturers Association and the AGMA Foundation.
This course will cover all aspects of gearbox concept, development, design, and through the initial stages of analysis as related to product requirements. We will review all the most common EV transaxle architectures, power flow and layout and the ‘whys’ of packaging as such. Independent of the architecture and / or layout, there are many similarities in the functional and operational requirements of an EV transaxle gearbox. We will work through all of those and develop a workable set of requirements that will then be used as the design basis. From a high-level point of view the ‘Big’ difference between transaxles for EVs (Electric Vehicles) and transmissions designed for more traditional Manual Transmissions (MTs) and / or Automatic Transmissions (ATs) is the lack of the ‘noisy’ internal combustion engine or ICE motor. An internal combustion engine driving into a typical gearbox provides a great deal of NVH masking. Thus, we obviously need to design quieter gearboxes to reduce the potential of observed gearbox NVH, now potentially unmasked by the lack of the ICE signature and magnitude. However, and moreover, the signature from an ICE is much different than from the electric motor. The new input signature, frequency, and magnitude, cause a shift to higher frequencies and generally lower magnitudes of vibrational energies. That in turn becomes a more significant consideration in terms of gear design and application. We will discuss this and more throughout the course.

Who Should Attend
This course will appeal to all involved in gear design, application, and analysis. Individuals more focused on actual EV gearbox design should gain value from the unique perspective brought to gear design specific to EV transaxles. We will discuss the specific and nuanced design details and development considerations related to the needs of an EV transaxle.
