As the automotive industry continues to move towards e-mobility, the manufacturing world is adapting to the respective requirements. Large gear ratios are necessary to reduce the high input speeds of electric motors to the required speed of the drive wheels. At the same time, masking noise of combustion engines is now missing, posing challenges to the noise level of transmissions. Principally, two main transmission concepts have become established for e-drive applications: two-stage layshaft transmissions with four gears, and planetary transmissions.
Zeiss and CleanControlling, a leading test laboratory for technical cleanliness, signed a cooperation agreement in April. The goal of the cooperation is to optimize products and industrial analysis techniques, and to set new market standards.
