Abstract
The invention relates to a level adjusting device, which comprises a support frame, a force applying shaft hinged to the support frame, a tilt angle sensor arranged on the force applying shaft, an installation part hinged to the support frame, an electric motor arranged on the installation part, a worm gear screw lifter, and a sensor enabling the electric motor to stop when a screw is triggered. The screw in the worm gear screw lifter is hinged to the force applying shaft, and the electric motor drives the worm gear screw lifter to drive the screw up and down. An external force applying mechanism drives the level adjusting device to vertically move, so that a to-be-tested tyre installed on the force applying shaft vertically presses a pressure bearing platform. Once the tilt angle sensor senses that the force apply shaft deviates from a level state, the electric motor drives the screw up and down to adjust the force applying shaft to be level. Therefore, the to-be-tested tyre always maintains vertical to the pressure-bearing platform, and accumulation deformation, due to pressure application by the external force applying mechanism and affecting the accuracy of a vertical stiffness test of the to-be-tested tyre, is avoided.
