Track-shoe of amphibious caterpillar vehicle

Abstract

The present invention provides a track-shoe of an amphibious caterpillar vehicle and more particularly, a track-shoe of an amphibious caterpillar vehicle with mobility on land and water, which comprises a space inside the track-shoe for conferring buoyancy to the track-shoe while simultaneously forming an arc-shaped groove for pushing out water at the frontal side of the track-shoe. The track-shoe of the present invention, in relation to the track-shoe of a caterpillar, which is placed over and between a driving wheel and a driven wheel at the respective frontal and rear sides of the two lateral sides of the main body of an amphibious caterpillar vehicle, comprises connection brackets, each forming a protrusion, side by side, on the front and the rear sides of the body of the track-shoe, for connecting two contiguous sections of the track-shoe; an angular protrusion at the lower side of the body of said track-shoe; an arc-shaped groove on the frontal side of the body of said track-shoe in the direction of rotation of the track-shoe of the caterpillar; and a hollow space inside the body of said track-shoe.

What is claimed is:  
     
         1 . A track-shoe of a caterpillar of an amphibious caterpillar vehicle, the caterpillar being installed between a driving wheel and a driven wheel which can rotate on both sides of the vehicle, and the track-shoe including: 
 a connection bracket formed protruding on the front and rear sides of the track-shoe body to interconnect adjacent track-shoes;    a hill-shaped protrusion formed below the track-shoe body;    an arc-shaped groove formed on the front side of the track-shoe body the hollow surface being in the direction of rotation of the caterpillar; and    a hollow space formed inside the track-shoe body.    
     
     
         2 . The track-shoe of  claim 1 , wherein the hollow space formed inside the track-shoe body is filled with buoyant material with low specific weight.
