An integrally joined two-piece motor vehicle steering knuckle assembly which includes a first component, preferably having a steering knuckle, a brake mounting bracket, a tie rod arm and, if needed, a steering rod arm, and a second component, preferably having a wheel spindle. The first component and the second component are integrally joined together by a process such as interference fit, welding and/or adhesive bonding, in the case of welding, most preferably friction welding, to form an integrally joined two-piece motor vehicle steering knuckle assembly.

Motor vehicle steering knuckle assembly

A self-steering assembly for self-steering wheels used on trucks carrying heavy loads includes a kingpin arm unit with a unitary adaptor collar at one end for mounting on a conventional tubular axle and a knuckle at the other end for retaining the clevis of a pivot link with a kingpin. The pivot link has a knuckle upon which is fixed a standard spindle unit having a steering arm secured thereto so that the assembly may be coupled to a similar assembly at the other end of the axle. A damper is pivoted at one end to the steering arm and at the other end to the axle. The self-steering assembly provides for the utilization of standard components in self-steering assemblies heretofore used only for steered axles.
