Abstract

An axle assembly for a drive device for the road wheels of a vehicle includes: a stationary housing having a housing interior at least partially filled with a lubricating liquid; axle housings connected to the stationary housing and configured to permit axles of the vehicle to pass towards the road wheels; a venting bore in one of the axle housings configured to allow pressurized air to escape from the stationary housing; and at least one rib sized and positioned in the housing interior of the stationary housing so as to prevent migration of the lubricating liquid out of the venting bore.
