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 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 installed with the possibility of vertical movement on a rotary frame between the caterpillar drive and the hydraulic pulsator, inside the vertical guide there are two guide rollers, the axes of which are connected to the rotary frame. On the side, the vertical guide in its middle part is equipped with a lateral support, on which a roller conveyor is fixed on top, and under the lateral support, perpendicular to the track belt, a horizontal lever is installed, one end of which is connected through an axis to the swing frame, the other end is connected to the hydraulic pulsator rod by means of two connecting rods located on both sides of the hydropulsator body. In the middle part of the horizontal arm, there is a support shaft, on which the side support of the vertical guide rests from above, and the upper branch of the track is fixed against lateral displacement by means of side rollers installed horizontally at the upper end of the vertical guide. In this case, a horizontal through hole of a rectangular shape is made in the side support of the vertical guide, through which an endless rubber-cord tape passes, rolled from the top along the roller table and from the bottom along two tension shafts installed on both sides on the side support.

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.
