Gearbox sealing device for sealing a motor vehicle's oil-filled differential gearbox has a sealing sleeve to slide into preliminary and final sealing positions

摘要

A sealing sleeve (SS) (3) slides on bearings on a shoulder formed on a differential casing (6) next to a casing opening (CO) (4) so that, in a first preliminary sealing position when a joint piece has not been fitted, a radial shaft sealing ring (RSSR) (2) fits on a gearbox casing (1) in front of the CO and forms a seal with a sealing lip on the RSSR against the SS.
