STAND FOR TESTING PNEUMATIC TIRES AND ELASTIC ELEMENTS OF VEHICLE SUSPENSIONS Russian patent published in 2022 - IPC G01M17/02 

FIELD: vehicles.

SUBSTANCE: invention relates to stands for testing elastic elements of vehicle suspensions and pneumatic tires. The stand for testing pneumatic tires and elastic elements of vehicle suspensions contains a base on which a traverse is installed by means of a frame movable in the vertical direction, connected to loads, a folding hydraulic cylinder, and a loading mechanism for the tested elements. The loading mechanism includes a caterpillar propeller and a pusher installed in a vertical guide and having support elements on the upper part, made in the form of rigid rollers installed in a checkerboard pattern, forming a roller conveyor. The test elements connected to the traverse are supported on the roller conveyor through a caterpillar belt covering the driven drum and the driving drum connected to the drive of the caterpillar propeller. The loading mechanism is installed on a pivot frame, the axis of which is fixed on the lower part of the stand base and coincides with the vertical axis of the tire loading. The pusher drive is made in the form of a hydraulic drive including hydraulic cylinders.

EFFECT: invention provides the ability to conduct bench tests of the suspension together with a wheel with a different profile of irregularities.
