Abstract
An adjustable gauge steering axle is disclosed which comprises an adjustable length beam and a steering control including a double-acting, dual piston rod hydraulic cylinder. Each piston rod of the hydraulic cylinder is connected to a corresponding steering arm through a respective strut which is adjustable telescopingly in length; a swivel joint intervenes between the rod and the strut.
Claims3
An adjustable gauge steering axle comprising an adjustable length beam and a steering control associated with said beam and including a double-acting, dual piston rod hydraulic cylinder with either each piston rod connected to a corresponding steering arm through a respective strut, wherein said struts are adjustable in length telescopically and linked to their respective piston rod, through an intervening swivel joint with each strut including a tubular sleeve;
- a first hollow tubular draw-out telescopically slidable in said sleeve and a second draw-out telescopically slidable in said first draw-out with the adjustment pitch distance on one draw-out being a sub-multiple of the adjustment pitch distance of the other draw-out, each draw-out being provided with notches at predetermined pitch intervals and means cooperating with said notches to lock said strut in adjusted position.

- wherein said struts are adjustable in length telescopically and linked to their respective piston rod, through an intervening swivel joint with each strut including a tubular sleeve;
- a first hollow tubular draw-out telescopically slidable in said sleeve and a second draw-out telescopically slidable in said first draw-out, each draw-out being provided with notches at predetermined pitch intervals and means cooperating with said notches to lock said strut in adjusted position, and
- wherein said beam comprises a tubular crosspiece having, at opposed ends thereof, two arms perforated at pitch intervals and fitting telescopically thereinto, said crosspiece being formed with holes adapted to receive a screw for locking the arms to the crosspiece, removably therein, the spacing between the centers of said holes being a sub-multiple of the spacing between the centers of the holes formed in each arm.
