METHOD FOR MONITORING TECHNICAL CONDITION OF DYNAMIC SYSTEM OF COURSE STABILITY OF CAR AT STANDS WITH RUNNING DRUMS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC G01L5/13 G01M15/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering, in particular to the technical diagnostics of the dynamic stabilization system (ESP). Essence: the car is mounted on the support rollers of the test stand with the wheels, the test mode of diagnostics is set by accelerating the inertial masses of the stand and the wheels of the car installed on the support rollers of the stand with the help of the power unit of the car, up to the initial speed of the activation of the ESP. Monitoring of the technical condition of the dynamic system of course stability of the car is carried out by measuring the longitudinal reactions on each wheel of the car and the stabilizing moment of the “car-stand” system when turning the stand. The device contains a frame with support rollers and four flywheels kinematically connected to each other by means of shafts, clutches and chain gears, rollers of tracking systems designed to measure the speed of wheel rotation, as well as devices for measuring braking forces on the wheels of the car located on the drive shafts of the support rollers. The device additionally contains a lifting and turning mechanism, including pneumatic chambers that provide lifting of the platform with the car, linear bearings on which the platform rotates relative to the axis of rotation, a hydraulic cylinder that turns the platform, the axis of rotation of the platform located at the intersection of the longitudinal axis of symmetry of the stand and the axis of rotation of the wheels, as well as a sensor of the stabilizing moment of the “car-stand” system, a sensor of the angle and speed of rotation of the platform.

EFFECT: expansion of the diagnostic functionality, which consists in the ability to set test modes for diagnosing the ESP.
