TEST STAND FOR PNEUMATIC TIRES AND ELASTIC ELEMENTS OF VEHICLE SUSPENDERS Russian patent published in 2022 - IPC G01M17/02 G01M17/04 

FIELD: engineering.

SUBSTANCE: stand contains a base, on which by means of a frame movable in vertical direction is installed a traverse connected to weights, a reclining hydraulic cylinder mounted between the traverse and the base, and a loading mechanism for the tested elements, including a crawler and a pusher connected to pusher drive mounted in a vertical guide with supporting elements on the upper part made in form of staggered rigid rollers forming a roller, to which through a caterpillar belt covering a driven drum connected to crawler drive, test elements connected to traverse are based. Loads are fixed on the top of the traverse. The loading mechanism is mounted on swivel frame, the axis of which is fixed to the lower part of stand base and coincides with the vertical axis of tire loading. The pusher drive is made in form of hydraulic pulsator having a rod with piston placed in housing that is mounted vertically on swivel frame of the stand to the side of crawler and is connected to pump and tank of hydroelectric power station through a servo-hydraulic distributor.

EFFECT: expansion of stand functionality, as well as facilitating the installation and testing including large diameter wheels.
