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 driving drum is made in the form of a wheel with a pneumatic tire, 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 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 pulsator having a piston rod, located in a housing, which is installed vertically on the swing frame of the stand to the side of the caterpillar propeller and communicated with the pump and the hydraulic station tank through a servo-hydraulic distributor. The pusher is made in the form of a vertical guide, equipped with short and long levers, installed horizontally in a vertical plane inside the caterpillar propeller perpendicular to the caterpillar belt. Moreover, the short arm is installed above the long arm and is pivotally connected by its ends to the left vertical support attached to the swing frame and to the vertical guide. The long lever at one end is pivotally connected to the left vertical support, at the other end by means of two connecting rods located on both sides of the hydraulic pulsator body, it is pivotally connected to the hydraulic pulsator rod and the middle joint is connected to the vertical guide. The upper branch of the track is fixed against lateral displacement by means of side rollers installed on the upper end of the vertical arm, the lower end of which is connected to the pusher through the axle, and behind the side rollers there is a roller that interacts with the right vertical support fixed on the rotary frame.

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.
