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, between the end of which and the base a screw mechanism is hinged, the axis of which is perpendicular to the radius drawn from the axis of the rotary frame to the screw mechanism hinge mounted on it. In this case, the axis of the swing frame 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. Wherein 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 caterpillar track is fixed against lateral displacement by means of side rollers installed horizontally at the upper end of the vertical arm, the lower end of which is connected through an axle to the vertical guide, and in the upper part opposite the side rollers on the vertical arm a roller is vertically installed, interacting with the right vertical support fixed to the swing frame.

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