  • Patent number: 6666771
    Abstract: A propeller shaft assembly (10) comprising a constant velocity universal joint (12) including a hollow shaft (20) and a connecting shaft (18) is provided. The hollow shaft (20) includes an aft open area (34) and is connected to an outer joint part (23) that has outer ball tracks (32). The connecting shaft (18) is connected to an inner joint part (25) that has inner ball tracks (46). A ball cage (26) that has a plurality of balls (28) is included. A standard plunge (22) that has an aft plunge portion (54) is also included. The aft plunge portion (54) and the aft open area (34) having inner diameters that are greater then or equal to an inner diameter D1 of the outer joint part (23). A first stop (55) limits the ball movement of travel in the aft direction. The first stop (55) is forcibly dispensable such that the connecting shaft (18) may release the first stop (55) and intrude significantly within the aft open area (34) which is outside a normal operating range (24).
