Abstract
A hub and wheel assembly for light load vehicle including baby carriages, infant strollers, wheelchairs and the like, the assembly having tandem wheels and a shock absorbing member in a trailing link suspension configuration. The assembly includes a wheel locking mechanism to lock one or both wheels into a secured position preventing the wheels from rolling about the axle. The wheel assembly incorporating a thrust bearing system to provide smooth and controlled swiveling relative to the vehicle body or frame and eliminates creeping and wobble. A swivel lock mechanism is also provided to allow the user to lock the tandem wheel assembly in a angular position relative to the vehicle body thereby preventing swiveling about the longitudinal axis of the swivel base housing. Each wheel is mounted to the axle in tandem using two low friction bearings and having a low-profile tire mounted to a rim with a reflective area for increasing safety in low elimination environments.
