On-board system and method of monitoring the technical condition of bearing nodes of road wheels of motor vehicles

Abstract

The on-board system for monitoring the technical condition of the bearing units of the road wheels of motor vehicles is characterized by the fact that it consists of a central processing and analysis unit (2) equipped with an LCD screen, an LED diode and a loudspeaker, located in the vehicle cabin, at a distance of up to 1 m from the driver's seat, measuring sensors - vibration acceleration (1), mounted on the hubs of the road wheels and communication cables (3) placed parallel to the cables of the wheel speed sensors of the anti-lock braking system.The method of monitoring the technical condition of the bearing nodes of the road wheels of motor vehicles consists in analysing in real time the acceleration of vibrations recorded on the bearing nodes of the road wheels of the vehicle generated while the vehicle is moving, the obtained results are transferred to the central processing and analysis unit (2), where they are processed and analysed with the results implemented in the database, and the monitoring result is obtained visually on the LCD screen of the central processing and analysis unit (2).
