ABSTRACT:
A multiple-tube propeller shaft assembly includes a first tube with a plurality of splines defining a splined portion, a second tube with a plurality of splines defining a splined portion, and a third tube with a plurality of splines defining a splined portion. In an embodiment, one end of the third tube is telescopically received within the first tube in a slip tube spline connection, while the other end is received within the second tube in a locked tube spline connection. In another embodiment, the first tube is telescopically received in one end of the third tube in a slip tube spline connection, while the second tube is received in the other end of the third tube in a locked tube spline connection. The propeller shaft assembly can be tuned to absorb crash energy between 0 and 50 kN.
