VEHICLE BRAKES DIAGNOSING HYDROMECHANICAL FORCE MEASURING STAND Russian patent published in 2002 - IPC

FIELD: measurement facilities. SUBSTANCE: invention relates to facilities for diagnosing condition of wheeled vehicle brake systems. Stand has two sections for mounting wheels of vehicle axle to be tested. Each section has two riffled rollers mechanically intercoupled by chain drive. Drive of rollers of each section in made in form of hydraulic jack installed horizontal and rigidly secured by base to frame of section. Brake force meter is made in form of pressure gauge communicating with underpiston space of jack working cylinder. Pressure gauge is provided with maximum pressure indicator and is made for supplying electric signals to computer. Scale of pressure gauge is made for reading brake force in proportion to pressure in underpiston space of jack working cylinder. Rod of jack is mechanically coupled with axle on one of rollers through flexible coupling and reverse stroke coupling by means of gear rack train and drive shaft. Brake installed on drive shaft is combined with flexible coupling. EFFECT: simplified design of stand, provision of facilitated transportation, possibility of operation in the field. 7 cl, 2 dwg
