A slip joint driveline (10) adapted for mounting between two universal joints (12, 14) is provided. The driveline (10) has an improved seal (25) for preventing infiltration of contaminants. The seal (25) is mounted on a slip shaft (16) and presents a flat surface (30) for engagement with a housing sleeve (22) to increase the seal interface and accordingly, provide superior scraping of the sleeve (22) by the seal (25). The seal (25) further avoids pneumatic lock in the driveline (10) by providing means for communicating air pressure (40) between the interior of the driveline (10) and the outside environment. A family of drive lines (10) is also provided having a weld yoke (12), stub yoke (14), a cylindrical housing sleeve (22), a female shaft (16) having internal splines (17), and a male shaft (18) having external splines (19) for slidably engaging the internal splines (17) of the female shaft (16). A plurality of individual drivelines having a particular length may be configured by cutting the sleeve (22) and female and male shafts (16, 18) to desired lengths before assembling each individual driveline (10). |
