Abstract
A constant velocity type of universal joint includes a sealing structure that avoids the use of a flexible boot. The constant velocity joint includes a hollow outer joint member, an inner joint member disposed within the outer joint member, and a plurality of ball bearings extending into associated grooves formed in the inner and outer joint members to provide a rotational driving connection therebetween. A sealing assembly is provided for protectively enclosing the components of the joint. The sealing assembly includes an outer sealing member that is sealingly connected to the outer joint member. An outer surface of an inner sealing member is slidably and sealingly engaged with an inner surface of the outer sealing member. An annular flange provided on the inner sealing member slidably and sealingly engages an outer surface of an annular element. An inner surface of the annular element slidably and sealingly engages a shaft connected to the inner joint member. The outer sealing member, the inner sealing member, and the annular element cooperate to form a protective enclosure for the various components of the joint. A biasing element can be provided to positively urge the inner sea…
