FIELD: mechanical engineering; automotive industry, test facilities. ^ SUBSTANCE: invention relates to diagnosing condition of brake systems of automobiles. Proposed test stand has follower rollers, flywheel and support rollers. Fitted on shafts of support rollers are devices for metering torques proportional to brake forces on vehicles wheels. Stand is made for setting into operation by means of vehicle under testing and changing of distance between front and rear platforms. Stand contains additionally three flywheels. Each of four flywheels of stand is arranged over perimeter, corresponds to wheel under test and is rigidly coupled with corresponding support rollers engaging with vehicle wheels and is mechanically coupled with other flywheels by means of V-belt drives and regulating shaft. Regulating shaft is installed in guides. Devices for metering torques proportional to brake forces on vehicle wheels installed on shafts of support rollers are located between support rollers and corresponds flywheels. Stand is furnished also with devices to determine angular velocities of support and follower rollers, weight devices to determine specific brake forces on each wheel, device for determining force of brake pedal, device to determine wheel braking time coupled with analog-digital converter connected with computer. ^ EFFECT: improved quality of determination of parameters of different brake system, including those furnished with antilock system. ^ 1 dwg |
