Variable length steering gear control shaft for motor vehicles - has first profile forming male element, coupled for telescopic sliding with one of its axially hollow ends in second tubular profile which forms female element

摘要

A variable length steering gear control shaft has two profiles mutually coupled in a coaxial manner in such a way that a first profile, forming a male element, is inserted with one of its axially hollow end zones into a second tubular profile, forming a female element. The profiles are mutually secured both against relative rotation and against relative movements in the axial direction. The end zone of (12.1) of the male profile (12) is coupled for telescopic sliding in relation to the female profile (11) by device (13) of mutual centring and connection provided in the same end zone and acting against the internal lateral surface of the female profile so as to ensure the correct mutual axial centring of the telescopically coupled profiles, and also the take-up and play and the damping of vibrations induced between the coupled profiles.
