A steer axle assembly is provided. The assembly includes an axle beam that defines a boss at one end. The boss defines one bore configured to receive a kingpin. The boss further defines two additional bores that intersect the kingpin bore and that are configured to receive draw keys used to secure the kingpin within the kingpin bore. The draw keys are both disposed on an inboard side of the kingpin. The assembly further includes nuts disposed about one end of the draw keys on the same side of the axle beam. The inboard location of the draw keys and the same-side location of the nuts reduces assembly time for the steer axle assembly and securely locks the kingpin within the bore.

Dual draw key arrangement for steer axle kingpin

A one-piece steering knuckle assembly for vehicles has a flanged body wherein the tie rod arm, hydraulic brake caliper bracket and, in some instances, the steering arm extend from the flanged body in a one-piece forged manner. There are enlarged bosses extending from the flanged body opposite the wheel spindle, the bosses having a bore which are axially aligned to receive a king pin. The flanged body, wheel spindle, tie rod arm and brake caliper bracket are all formed from a single steel billet as a one-piece heavy duty forging. Such a design eliminates the brake caliper/knuckle joint and the tie rod arm/knuckle joint, and thus, it results in savings in assembly time and weight.

One-piece forged steering knuckle assembly

A non-driven tubular vehicle axle assembly in which the axle body is formed from the mating of opposing axle sections constructed of sheet material formed into channel members. The utilization of channel members of differing lengths combined in the construction of the axle body along with separately formed spring pads and knuckle/king pin mountings provides for ease of assembly of axles of various length and specification.
