2091545 9205968 PCTABS00011 A hub and wheel assembly (2) for light load vehicles including baby carriages, infant strollers, wheelchairs and the like having tandem wheels (4) and shock absorbing means in a trailing link suspension configuration. The assembly (2) includes a wheel locking means (16, 17, 22, 24, 26) to lock one or both wheels (4) into a secured position preventing the wheels (4) from rolling about the axle (18) and swivel means (6) to allow the wheel assembly (2) to swivel relative to the vehicle body or frame. The swivel means (6) incorporates a thrust bearing system (36) to provide smooth and controlled swivelling and elimination of creeping or wobble. A swivel lock means (37, 46, 40) is also provided to allow the user to lock the tandem wheel assembly in a linear position (43) preventing swivelling about the longitudinal axis of the swivel base housing (8). Each wheel (4) is mounted to the axle (18) using two low friction bearings and having a low profile tire (42) mounted to a rim (44) with a reflective area (5) for increasing safety in low illumination environments.
