ABSTRACT:
This invention relates to a shock absorbing type steering shaft for steering front wheels of a vehicle by converting rotation of a steering wheel to reciprocation of a tie rod, and to a method of manufacturing the steering shaft.
The steering shaft has energy absorbers formed by filling a synthetic resin between the shaft and an outer sleeve. This steering shaft comprises a plastic metal pipe including, in a region remote from the steering wheel, a flat portion for connection to the outer sleeve, and a plurality of annular grooves to be filled with the synthetic resin. In a region adjacent the steering wheel, the plastic metal pipe includes an upper bearing mount, a screw for engaging a bearing retaining nut, a serrated shaft for engaging the steering wheel, and a screw for engaging a retainer nut, all defined as integral parts of the plastic metal pipe and arranged in the stated order toward an extreme end of the pipe. This steering shaft is lightweight, and may be manufactured in a reduced shaping time and at low cost.
