ABSTRACT:
The invention provides a lightweight, economical rack steering mechanism comprising a booster pressure cylinder having a piston mounted on a toothed rack engaged by a pinion carried by an end closure element secured to the cylinder which has an end closure element at its opposite end. The rack extends in each direction out of the closure ends which effect housings for respective cylinder ends. The rack ends have connection to steering linkage means. The particularly novel feature is the use of lightweight metal, e.g., aluminum tubing, for the pressure cylinder. The mode of securing is by means of a corrugation adjacent each end of the cylinder which effects means in conjunction with locking or securing nuts and clamping or locking rings for fastening the housing ends to the cylinder. The aluminum tubing is protected against abrasive and twisting effect of nut tightening by arranging the securing nuts to abut the clamping rings which abut respective tubing corrugations nonrotatively. The securing nuts are rotatively tightened to grip the tubing through the clamping rings, being carried threadedly in respective end elements.
