A multi-piece propeller shaft includes a constant velocity joint disposed between and operably interconnecting first and second shaft segments. The constant velocity joint includes an outer race extending along an axis A from a first outer race end operably connected to the second shaft segment to a second outer race end to define an inner surface bounding an internal cavity. A vent and seal assembly is disposed inside the outer race and defines a plurality of venting cavities disposed serially along the axis A in fluid communication with one another. A first one of the venting cavities is disposed in fluid communication with the internal cavity and a last one of the venting cavities is disposed in fluid communication with an environment of the constant velocity joint for venting air from the internal cavity to the environment.

Vehicle driveline joint including a vent and seal assembly

A joint assembly for connecting a first rotating part and a second rotating part. The joint assembly includes a constant velocity joint that has an inner race for being connected to the first rotating part and an outer race that is pivotable relative to the outer race. A mating flange couples the outer race to the second rotating part. The outer race and the mating flange each have a radially inner surface. A piloting cover is positioned axially between the outer race and the mating flange and radially supports the radially inner surface of the outer race at a first pilot point, and radially supports the radially inner surface of the mating flange at a second pilot point for centering the outer race relative to the mating flange. The first and second pilot points are located radially inwardly of a bolt circle diameter.

Joint assembly having a piloting cover for centering a mating flange relative to an outer race of a constant velocity joint

A seal and vent assembly for a constant velocity joint including a vent plate for being disposed in a compartment of the constant velocity joint. The vent plate defines a mounting aperture. A vent valve is received in the mounting aperture for sealing the compartment of the constant velocity joint. The vent valve has a body portion extending along an axis and received by the mounting aperture and a rim portion extending from the body portion into engagement with, and biased against the vent plate. The vent valve defines a chamber between the rim portion, the body portion and the vent plate. A venting channel fluidly connects the chamber of the vent valve and the compartment of the constant velocity joint. The vent plate defines the at least one venting channel.

Seal and vent assembly for a vehicle driveline

An outer joint member for a joint assembly configured to receive an inner joint includes a wall forming a hollow chamber having a closed end and an open end. A plurality of restrictors are coupled to the hollow chamber each having a portion thereof extending outwardly from the inner surface of the wall of the hollow chamber. The plurality of restrictors extending from the inner surface of the wall proximate the open end of the hollow chamber.
