Abstract
A steering axle for use in a vehicle such as an industrial truck or the like comprises a center beam member having spindles mounted for pivotal movement at each end thereof for rotatably supporting a pair of wheels. A double-acting motor is secured to the axle between the spindles and is connected by steering links to the spindles. The hydraulic motor comprises a double-acting piston having its rods extending outward and connected at their ends to the axle beam member for stationary mounting of the piston. A cylinder is reciprocally mounted on the piston and rods and is connected at each end by means of a pair of links to a pair of steering arms for each of the spindles. The geometric relationship of the steering motor and the steering arms are such that the angles between the axis of the cylinder and the links connected to the steering arms will be equal when the spindles are such that wheels mounted thereon would be straight ahead or in the fully cramped position. This arrangement provides a compact arrangement having minimum stress on the steering components.
