An automobile wheel hub bearing damage detection and alarm system

Abstract

Disclosed is an automobile hub bearing damage detection and alarming system. The automobile hub bearing damage detection and alarming system is composed of a liquid crystal display screen, a controller, a voice alertor, a ZigBee router and a wireless bearing damage detector; the liquid crystal display screen is used for displaying hub bearing abnormal information; the controller is used for processing information received by the ZigBee router, meanwhile controlling the liquid crystal display screen to display the information and controlling the voice alertor to provide hub bearing damage alarming information for a driver; the ZigBee router is used for receiving the hub bearing damage alarming information detected by the wireless bearing damage detector; and the wireless bearing damage detector is used for monitoring the damage situation of a hub bearing in real time. When abnormal change of the hub bearing occurs, the abnormal information is sent to the ZigBee router in a glove compartment on an automobile instrument board through a ZigBee terminal node, the information received by the ZigBee router is displayed on the liquid crystal display screen through the controller, and meanwhile the voice alertor provides the hub bearing abnormal information for the driver.

Description

technical field [0001] The invention relates to a damage detection and alarm device for a bearing, in particular to a damage detection and alarm system for an automobile hub bearing. Background technique [0002] Bearings are part of the driving device of the car. During the driving process of the car, the hub bearing is the most prone to failure parts. Due to the long-term heavy load driving of the high-speed rotating bearing, it is very prone to surface peeling, fatigue, cracks and other failures, which seriously affects the The safety of the car during driving, especially the car running on the highway, when its hub bearing is damaged, it is very easy to cause accidents such as rollover and loss of control of the car. [0003] In the prior art, the common method for detecting the damage of the automobile wheel hub bearing is to set up the vehicle, put the gear into gear to rotate the wheel, and listen carefully to see if there is a buzzing sound. There are certain defects...

[0002] Bearings are part of the driving device of the car. During the driving process of the car, the hub bearing is the most prone to failure parts. Due to the long-term heavy load driving of the high-speed rotating bearing, it is very prone to surface peeling, fatigue, cracks and other failures, which seriously affects the The safety of the car during driving, especially the car on the highway, when its wheel hub bearing is damaged, it is very easy to cause the car to roll over, lose control and other accidents

[0003] In the prior art, the common method for detecting the damage of the automobile wheel hub bearing is to set up the vehicle, put the gear into gear to rotate the wheel, and listen carefully to see if there is a buzzing sound. There are certain defects in this method. Drive, some are full drive, so this method can only judge whether the bearing of the driving wheel is damaged; 2. This method does not have real-time monitoring, so it is impossible to know whether the hub bearing is faulty
