FIELD: testing technology.

SUBSTANCE: loading mechanism is mounted on a swivel frame, the axis of which is fixed to the lower part of the base of the stand and coincides with the vertical axis of the tire loading. The pusher drive is made in the form of a hydraulic pulsator having a rod with a piston placed in a housing that is mounted vertically on the swivel frame of the stand to the side of the crawler and is connected to the pump and tank of the hydroelectric power station through the distributor. The pusher is made in the form of a vertical guide installed with the possibility of vertical movement on the swivel frame between the crawler and the hydraulic pulsator. Two guide rollers are installed inside the vertical guide, the axes of which are connected to the swivel frame. On the side, the vertical guide in its middle part is equipped with a side support, on which a roller table is fixed from above. A horizontal lever is installed under the side support perpendicular to the track belt. In the middle part of the horizontal lever, a support shaft is installed, on which the lateral support of the vertical guide rests from above.

EFFECT: possibility of bench testing of a single-support suspension unit together with a rolling wheel, as well as facilitating the installation and testing, including large-diameter wheels.
