During vehicle operation, powertrain components (such as axles/e-axles, traction motors, transmissions, and limited slip couplings/E-LSDs) undergo rapid differential pressure changes that can stress their seals and gaskets. Housings must have a way to exchange air with the environment while keeping out water, dirt, and debris that can harm lubricants and erode parts. Venting is used to equalize pressure while preventing the ingress of contaminants.
Several advancements have occurred in powertrain venting:
