Differential power transfer transmission, with friction coupling, oil reservoir and sealing device

摘要

The transmission has an outer rotary part and an inner rotary part inside it. There is a friction coupling between the two parts through which a pressure force is exerted. Oil lubricates at least this coupling. Oil mist is present between the inner and outer rotary parts. A sealing device (165) retains the oil in the oil cavity. There is an oil reservoir on the inner wall surface of the outer rotary part.
