TESTING BED METHOD DETERMINING MECHANICAL LOSSES IN TIRES Russian patent published in 1997 - IPC

FIELD: tests of wheels of motor vehicles, in particular, wheels with rubber pneumatics. SUBSTANCE: test of system "roller testing bed - wheel" is carried out in two stages. At first stage losses in system are determined with the use of nondeformed analog of wheel. At second stage losses in system are found with its spinning together with tested wheel. Loses in tire are determined by difference of results of tests at second and first stages. EFFECT: enhanced reliability of method. 1 cl, 2 dwg
