Temperature monitoring system for automobile hub and working mechanism thereof

Abstract

The invention relates to the field of automobile parts and discloses a temperature monitoring system for an automobile hub and a working mechanism thereof. The temperature monitoring system comprises a direct-current power supply, a controller, a temperature controller, a first electronic switch, a water storage tank, an electromagnetic valve and a water spray head, wherein the temperature sensor is mounted on the automobile hub; and the water spray head is mounted near the automobile hub, and a nozzle faces the outer surface of the automobile hub. Through the way, the working state of corresponding water spray device can be controlled in real time according to the real-time temperature monitoring data of the automobile hub, then the hub temperature can be reduced by water spraying when the hub temperature is ultrahigh, the failure and safety hazard caused by ultrahigh hub temperature are avoided, and the driving safety of the automobile is guaranteed. Moreover, the temperature monitoring system also has the characteristics of acousto-optical alarm, high automation degree, simple structure, easiness in implementation, low cost and the like while the practicability is high and practical promotion and application are facilitated.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a temperature monitoring system for an auto hub and its working mechanism. Background technique [0002] When the car is running, if the temperature of the wheel hub is too high due to the failure of braking, braking on a long downhill, the failure of the brake hub sprinkler, the damage of the wheel hub bearing, and the excessive bearing clearance after the wheel hub adjusting nut is withdrawn, etc. If the phenomenon is high, the following failures and safety hazards will occur: (1) The brake pads (brake shoes) will cause the brake hub or brake disc to crack or deform in the overheated state, thereby reducing the braking force or even losing the braking force ( For example, when the brake pads crack and fall off, the braking force is completely lost), if the temperature of multiple hubs is too high, the braking force of the whole vehicle will be greatly reduced, resulting in brake failu...

[0002] When the car is running, if the temperature of the wheel hub is too high due to the failure of braking, braking on a long downhill, the failure of the brake hub sprinkler, the damage of the wheel hub bearing, and the excessive bearing clearance after the wheel hub adjusting nut is withdrawn, etc. If the phenomenon is high, the following failures and safety hazards will occur: (1) The brake pads (brake shoes) will cause the brake hub or brake disc to crack or deform in the overheated state, thereby reducing the braking force or even losing the braking force ( For example, when the brake pads crack and fall off, the braking force is completely lost), if the temperature of multiple hubs is too high, the braking force of the whole vehicle will be greatly reduced, resulting in brake failure, vehicle loss of control and traffic accidents (about 80% of light and heavy vehicles) The brake failure fault is caused by the high temperature of the hub, which will cause serious traffic accidents); (2) The high temperature of the hub will cause the bearing oil to lose its viscosity and make the lubrication invalid, resulting in damage to related components such as bearings and wheel cores; ( 3) Extremely high temperature of the wheel hub will cause the tire rubber to burn and cause air leakage. When the temperature is extremely high, it may even cause the lubricating oil in the tire and the wheel hub to burn, thereby causing the entire vehicle and goods to burn (70% of light and heavy vehicles on the road spontaneously ignite due to the temperature of the wheel hub) caused by super high)
