FIELD: transportation. ^ SUBSTANCE: test stand for amphibious vehicles has basin with entrance and exit ramp, side walls, road, ramp and basin borders. From both sides of exit ramp pits are made in which ends of tubular shaft are embedded. Parallel arms-brackets of sheet metal are attached to the shaft equally spaced from axis. Between attached arms-brackets, spacer pipe is preliminary embedded on shaft which pipe has rectangular pawl with holes on both sides. By means of these holes the pipe is attached to captivating sheet located on symmetry axis of exit ramp. At the end of arms-brackets with lugs, cylinder is attached on axis. This cylinder is made along generator of curve corresponding to curve of vehicle front bumper. Tube rings with pawls are put on shaft ends. The pawls are fixed on pit floors. Spheroidal flanges are fixed on shaft ends to which flanges arms are attached, with brought-out from pits ends having lugs, and pneumatic cylinders are attached to arms from two sides. ^ EFFECT: reduction of scope of work during test stand construction and provides getting true data about capability of vehicle to move over water surface on tired wheels. ^ 2 dwg |
