  • Long plunge VL joint
    Patent number: 6585601
    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 outer joint part (23) having an outer race surface (31) that includes an outer forward portion (32) and an outer rearward portion (34). The connecting shaft (18) includes an inner joint part (25) having an inner race surface (33) that includes an inner forward portion (35) and an inner rearward portion (36). The connecting shaft (18) further includes a recessed surface portion (38). A ball cage (26) that has a plurality of torque transmitting balls (28) is included. During a collision, the torque transmitting balls (28) translate off said inner race surface (33) and drop into the recessed surface portion (38) allowing the connecting shaft (18) to collapse into the hollow shaft (20).
