Abstract

The present invention describes a wheeled apparatus (100) for carrying a load or a person. A travel wheel (150, 150a) or travel wheels (150, 150a) of the wheeled apparatus (100) is/are suspended by each associated pivot link member (105, 105a-105e) to a chassis (102) of the wheeled apparatus; the pivot link member is free to pivot when the wheeled apparatus travels over an uneven terrain; as a result, the wheeled apparatus experiences reduced impact forces and this invention thus provides a user a smooth ride over an uneven terrain.
