Steering mechanism for tractors.

摘要

A steering mechanism for improving the turning radius of a tractor or other vehicle is disclosed wherein the wheels (19) are turned relative to the steering axle (18) on pivotal movement of the steering axle relative to the chassis (10) of the tractor. A connecting link (50) interconnects the pivot mechanism (31) pivotally supporting the steering axle (18) relative to the chassis (10) with the steering mechanism such that a manipulation of the steering mechanism to affect a turning of the wheels affects a pivotal movement of the steering axle in the same direction the wheels (19) are being turned. The pivot mechanism (31) allows for pivotal movement of the steering axle (18) about longitudinally extending horizontal axis (23) in addition to the pivotal movement of the steering axle about a generally vertical axis relative to the chassis. A lost motion linkage (45) interconnecting the pivot mechanism and the steering axle accommodates differences in arcuate movements due to the pivot mechanism and the steering axle pivotally moving about longitudinally spaced pivot centers (36,38). The pivot mechanism (31) effects a lateral shifting of the steering axle during rotation thereof about the pivot axis (38). <IMAGE>
