ABSTRACT:
A kingpin assembly for heavy duty vehicles having upper and lower yokes of a steering spindle knuckle straddling upper and lower sides of an end portion of an axle. The upper and lower steering spindle yokes have respective bores in registration with a bore in the axle end portion. A kingpin has a central portion fixedly secured within the axle bore, and has opposite, accurately machined and polished end portions disposed within respective upper and lower steering spindle yoke apertures. There is an annular gap between the peripheries of the kingpin end portions and the interior surfaces of the steering spindle yoke bores. An annular sleeve resides within the gap. A pair of roller bearings are mounted in spaced relation internally of the sleeve, with a grease reservoir being defined in the space between adjacent roller bearings. The roller bearings have an outer race mounted in a stationary position on the internal wall of the sleeve. Rolling elements are disposed between the kingpin end peripheries and the respective races for rolling surface contact with the peripheries of respective kingpin ends and races to provide low friction oscillatory movement of the steering spindle knuckle with respect to the axle end.
