Abstract
A suspension structure for a front wheel assembly of a wheelchair generally includes struts of front wheel assemblies disposed at corresponding mounting brackets on the frame of the wheelchair. The struts will rotate upward about the corresponding jockey wheels when the jockey wheels are passing an obstacle, and meanwhile it will effect an uplift of the front end of the frame of the wheelchair. As a result, the gravity center of the user will be shifted backward so as to reduce the load on the jockey wheels, by this way, the jockey wheels may traverse the obstacle without difficulties. Furthermore, the suspension for the front wheel assembly of a wheelchair is simply structured so as to facilitate the assembly and reduce the production cost as well.
