Lash-free cable drive

摘要

A power system including a cable drive for adjusting a steering column of an automotive vehicle in response to rotation of a jack screw. A cable transmits torque from a motor-driven output shaft to the jack screw. The cable has terminal portions received in sockets in the output shaft and in the jack screw. The terminal portions and the sockets are square in cross section. An end part of each terminal portion is twisted to cause comers of the terminal portion to interfere with corners of the socket into which it extends to provide substantially a lash-free connection between the terminal portions of the cable and the sockets.
