Drive line apparatus

摘要

A drive line apparatus has a pair of tubular shafts configured to fit telescopically. The outer shaft has internal splines and the inner shaft has outer splines so that the shafts rotate in unison. Each of the outer and inner shaft has one partially closed end for coupling to an individual joint, wherein the joint connected to the partially closed end of the inner shaft is disposed within the inner shaft for further reducing the length of the drive line apparatus.
