Abstract
A pinion adjustable assembly for steering mechanisms for automotive vehicles, a pinion-rack set incorporated in a pinion housing and a tubular cylindrical bushing with free angular displacement that is positioned inside the housing and is coupled to an angular positioning nut. The said bushing has an eccentric inner wall with regard to outer wall surface surrounding a pinion housing. Angular displacement of said bushing by angular movement changes its eccentricity to allow the pinion to move relative to the rack bar for overcoming wearing out effect on teeth.
Claims8
A steering mechanism for an automotive vehicle comprising:
- a pinion shaft having a pinion gear formed thereon;
- a rack casing receiving said pinion shaft and said pinion gear;
- a bushing rotatably coupled to said rack casing and said pinion shaft, said bushing being received within said rack casing, said bushing receiving said pinion shaft therein, said bushing having an inner diameter eccentric with said rack casing, said bushing positioning said pinion shaft with respect to said rack casing in a first position and a second position, said first position urging said pinion gear toward a rack a first distance, said second position urging said pinion gear toward said rack a second distance, said bushing having a first end with a flange integrally formed therein for preventing said bushing from passing through said rack casing in a first axial direction, said bushing having a second end with a threaded fastener integrally formed therein;
- and
- a nut having an opposing threaded fastener, said opposing threaded fastener being engaged to said threaded fastener of said second end of said bushing so as to prevent said bushing from passing through said rack casing in a second axial direction.
