ABSTRACT:
The present invention relates to a design of a driving mechanism for a vehicle to move through uneven terrain including stairways. The link-type double track mechanism in accordance with the present invention comprises: front and rear track driving sections; a built-in type control box; a set of angle-adjusting flippers, installed at front and rear ends of the control box, for adjusting the track angle; and high-speed driving wheels installed at the angle-adjusting tracks and imbedded inside. The link-type double track mechanism in accordance with the present invention does not require a complex terrain-adaptation mechanism, and thus it has advantages that the overall structure is simple and the control is very easy.
