FIELD: equipment for timely test of adhesion qualities of built and used road with hard pavement, air fields, investigations of road incidents. SUBSTANCE: facility evaluating adhesion qualities of road with hard pavement includes tire simulator, main and additional loading mechanisms kinematically coupled to it and mounted on guiding bearing frame and indicator of value of adhesion coefficient. Salient feature of invention lies in that main loading mechanism comes in the form of pair of upper and lower carriages intercoupled through springy element in the form of coil spring and mounted for joint travel in guides of bearing frame. Tire simulator made in the form of block comprising steel plate and rubber is attached to lower carriage to which additional loading mechanism is coupled too. EFFECT: increased accuracy of evaluation of adhesion qualities of road with hard pavement thanks to utilization of friction coefficient at rest in the capacity of friction coefficient and exclusion of human factor from measurement process. 4 cl, 1 dwg |
