Power management company Eaton announced its Vehicle Group is developing gearing solutions for electric vehicles (EVs). The new technology complements Eaton’s eMobility power electronics portfolio in the electrified vehicle powertrain market.
Eaton conducts a total system analysis, using state-of-the-art tools and in-house expertise, to design EV gearing solutions that are optimized for efficiency and reliability, with low noise and manufacturing costs. Several factors gears, bearings, and lubrication systems influence the development of gearing solutions. To achieve optimization in these three areas, Eaton applies a series of in-house design and manufacturing techniques, including:
- Gear root geometry optimization for maximum strength.
- Micro and macro gear geometry modelling to improve NVH (noise, vibration and harshness), efficiency, and reliability.
- Thrust load and bearing loss minimization to improve reliability and simplify or downsize bearings.
- Simulation and selection of lubrication solutions for full-system reliability and efficiency.
