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. The driving and driven drums are made in form of wheels with pneumatic tire. The loads are fixed on the top of the traverse. The loading mechanism is mounted on a swivel frame, the axis of which is fixed to the lower part of the base of the stand and coincides with the vertical axis of the tire loading. The pusher and its drive are made in form of a hydraulic pulsator having a rod with a piston placed in a housing that is mounted along the vertical axis of tire loading on swivel frame of the stand inside the crawler and is connected to the pump and tank of the hydroelectric power station through a servo-hydraulic distributor. The roller is mounted on rod of hydraulic pulsator. The upper branch of the track belt is fixed from lateral displacement by means of wide side roller mounted on swivel frame, the axis of which is parallel to vertical axis of tire loading.

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