TEST BENCH FOR TRACTION-ADHESION PROPERTIES OF COATED TIRES Russian patent published in 2020 - IPC G01M17/02 

FIELD: test.

SUBSTANCE: invention relates to the field of test equipment and can be used for assessment of traction-coupling properties of tires. According to the invention, the tires are run-in on the ring-shaped coating. Test bench comprises at least one or a number of paired radial working structures 1 kinematically connected to propulsor 3 and rotary motion drive 4, stand control unit 9 located in the platform central part on base 7. Each structure 1 of the stand includes dynamic link 6, road wheel 8 installed with possibility of dynamic action on the coating during its running-in, main link 5 with mechanically driven frame 12 with a load of variable mass installed on it with the possibility of its movement along main link 5. Load on dynamic link 6 can vary both by changing weight and by changing centre of mass using mechanically driven frame 12. Specified dynamic load on the side of road wheel 8 of both passenger and cargo vehicle is tested practically in real conditions.

EFFECT: technical result is reduced power consumption of drive during stand operation due to possibility of load adjustment without its stop.
