Brake cooling water monitoring device for automobile

Abstract

The invention discloses a brake cooling water monitoring device for an automobile, belongs to a brake safety monitoring device, and aims to provide a device capable of monitoring a brake water spray system in real time. The device comprises nozzles arranged on brake hubs, a cooling water pipe communicating the nozzles, and conductive probes (5) arranged on the nozzles (9); four control ends of a quad bilateral switch integrated circuit module (10) are electrically connected with the conductive probes (5) corresponding to the four control ends respectively; each control end correspondingly controls an internal control switch; a positive terminal of each internal control switch is respectively connected in parallel with an anode of a power supply through a monitoring pilot light (1), while a negative terminal is respectively connected in parallel with a cathode of the power supply through a bias resistor R; and the nozzles (9) are electrically connected with the anode of the power supply through conducting wires. The monitoring device has the advantages of simple structure, convenient use, low cost, high reliability and the like, and can be used for various autotrucks.

Description

Technical field: [0001] The invention relates to a safety monitoring device for automobile brakes, in particular to a device for monitoring cooling water of automobile brakes. Background technique: [0002] As we all know, whether the brake device can work normally is the key to ensuring driving safety. During the braking process of the truck, the brake pads will rub against the brake hub violently and generate high temperature, which will cause the brake pads to wear out rapidly and the brake hub to burn red, resulting in brake failure; especially for large-tonnage trucks when they go downhill for a long distance During the continuous braking process, the above phenomenon is more serious. In order to avoid brake pads and brake hubs from overheating and causing brake failure, the usual measure is to install a water spray device near the brake hub to cool down the brake pads. However, since the vast majority of trucks are not equipped with a brake cooling water monitoring d...

AI Technical Summary

Problems solved by technology

However, since the vast majority of trucks are not equipped with a brake cooling water monitoring device at present, once the water spray device is blocked or lacks water, it may cause a major traffic accident; in order to be able to monitor the braking system at any time, the application No. "01226211.0", the name is "automobile brake system cooler device", the application number is "200810045952.X", the name is "brake hub cooler", and the application number is "200410012719.3", the name is " The invention patents of "method and device for fault detection of motor vehicle braking system" all disclose technical solutions for using temperature sensors to monitor the temperature of brake pads, but none of these technical solutions can prevent problems before they happen

This is because when the temperature of the brake pads and the brake hub rises, if the water spray device is blocked or lacks water, etc., emergency braking measures cannot be taken.
