Abstract
A novel arrangement of a steering axle for a land vehicle having a hydrostatic drive system, wherein a hydraulic motor assembly is directly mounted on a steerable wheel of the axle and adapted to be movable with the wheel, is disclosed. The steering axle comprises a pair of kingpin assemblies pivotally mounting steering knuckles to axle yokes. An upper kingpin assembly pivotally attaches the steering knuckle to the axle yoke, and, at the same time, provides a hydraulic swivel coupling between the wheel mounted hydraulic motor and the rest of the hydrostatic drive system of mounted on the vehicle, that prevents the bending of the hydraulic hoses conveying hydraulic fluid, by steering movements of the front steerable wheels.
