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

FIELD: automotive industry.

SUBSTANCE: substance of the invention lies in the fact that the weights are fixed on top of the traverse, and the loading mechanism is installed on a pivot frame, the axis of which is fixed on the bottom of the stand base and coincides with the vertical axis of the tire loading. The pusher and its drive are made in the form of a hydraulic pulsator having a piston rod, located in a housing, which is installed along the vertical axis of the tire loading on the rotary frame of the stand inside the caterpillar propeller and communicated with the pump and the hydraulic station tank through a servo-hydraulic distributor. The pusher in the upper part is equipped with two tension shafts and an endless rubber-cord band, covering the roller conveyor mounted on the hydraulic pulsator rod. The upper branch of the track is secured against lateral displacement by means of a wide side roller mounted on the swing frame, the axis of which is parallel to the vertical axis of the tire loading. The vertical guide of the pusher is made in the form of two guide axle boxes installed on both sides of the hydraulic pulsator body parallel to its axis and fixed on the swing frame. Inside the guide boxes there are guide rods, the upper ends of which are connected to the roller conveyor.

EFFECT: possibility of carrying out bench tests of a single-support suspension unit together with a rolling wheel without and with lateral tire slip on a hard surface with a different profile of irregularities, including the random nature of their distribution, as well as facilitating installation and testing, including wheels of large diameter.
