Slidable mounting for disc brake yoke - has resilient bush sleeve with external annular recesses, scraper rings and lip seals at ends

摘要

The arrangement is intended for slidably carrying the yoke of a disc brake on an axial bolt (4) of a carrier. The yoke has a cylindrical bore (5) with a resilient sleeve (6) fixed in it whilst the sleeve contains (7) a bush (8) slidable on the bolt and scraper rings (13) at both ends of the bore which are radially movable relative to the yoke. The cylindrical outer surface of the sleeve has axially spaced circumferential recesses (9). Its ends have sealing lips (10) between the ends of the bush and the scraper rings. These lips point outwards away from the bush and are in sealing contact with the bolt.
