Abstract
A brake pad with an attached steel wire mesh relates to the manufacturing field of auto parts. The brake pad with the attached steel wire mesh comprises a brake pad body, a thin steel wire mesh, heat-sensitive sensors, copper wires and a singlechip. The steel wire mesh is attached along the diagonal direction of an upper surface and a lower surface of the brake pad, and the heat-sensitive sensors are installed on the steel wire mesh attached to the inside of the brake pad. The heat-sensitive sensors can sense heat generated from abrasion of the brake pad and send information of thickness of the brake pad to the singlechip at any time. The brake pad with the attached steel wire mesh can effectively prevent brake failure caused by serious abrasion of the brake pad, thereby reducing the number of traffic accidents.
Description
Technical field:
The utility model relates to auto-parts and makes the field, is specifically related to a kind of brake block that attaches steel wire that adds.
Background technique:
Brake block is mainly used in the brake of communications and transportation such as automobile, motorcycle.At present, automobile mainly is made up of through the high temperature compacting steel disc, friction material layer, bonding thermal-protective coating with brake block.In the brake process of automobile, friction material layer and brake disc mutual friction mutually produce the braking force of automobile, and friction material layer constantly wears and tears, and mainly are that the thickness of friction material layer is more and more littler thereby make the thickness of brake.In some cases, it is different that abrasion degree in the left and right sides also can take place brake block, and brake block was lost efficacy.When friction material thickness may wear to certain limit, must in time change brake block.If the very thin thickness of brake block friction material and in time not changing; After friction material uses up and uses; Base plate will directly contact with brake disc, finally can lose braking effect and damage brake disc, and the cost of repairs of brake disc is very expensive; So in time the abrasion condition of induction friction material not only helps the maintenance of automobile, more can reduce traffic accident.
In the brake block that uses at present, major part is not installed brake block wearing and tearing warning device, generally confirms the degree of wear of brake block according to the explanation estimation, because the situation of driving is different, can accurately not judge the opportunity of changing brake block like this.If can the thickness of brake block friction material be detected, when brake block friction material may wear to a certain degree, detection device can provide the information of the degree of wear.
The model utility content:
The purpose of the utility model provides a kind of inside and adds and attach the brake block of the special finer wire net of one deck as warning device, collects the information of brake block wearing and tearing through the heat sensitive sensor on the steel wire, sends the information of brake block thickness at any time to single-chip microcomputer.Can effectively prevent the brake failure that causes owing to the brake block serious wear, reduce the generation of traffic accident.
For existing problem in the technical solution background, the utility model is to adopt following scheme: a kind of inside adds the brake block that attaches special steel silk screen warning device, comprising brake block body, finer wire net, heat sensitive sensor, copper wire, single-chip microcomputer.
It is characterized in that: brake block inside adds on the steel wire that attaches is equipped with heat sensitive sensor, can respond to the heat that produces when brake block weares and teares, and sends the information of brake block thickness at any time to single-chip microcomputer.Wherein the material of finer wire net is a steel wire, and diameter is 0.05mm, and the diameter of processing mesh is 3mm.
Steel wire adds along the diagonal of brake block upper surface and lower surface and attaches, and at three heat sensitive sensors that are equipped with apart from the horizontal line equal intervals at brake block upper surface 1.5mm place, each sensor is drawn a lead.Downward successively, every load onto three sensors at a distance from 1.5mm is equally spaced, draw 12 leads altogether, the sensor on every lead has all been represented the height of diverse location.Lead is drawn from the brake block side, is connected on the single-chip microcomputer, through the single-chip microcomputer processing signals.
The beneficial effect of the utility model: when just wearing and tearing took place brake block, sensor topmost touched brake disc at first, and signal is sent on the single-chip microcomputer, demonstrates the abrasion condition of brake block friction material.Along with the brake block increase of service time, constantly aggravation of the friction material of brake block wearing and tearing, when the sensor of the bottom touched brake disc, control circuit was through the Single-chip Controlling alarm equipment alarm.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the distribution schematic diagram of the utility model heat sensitive sensor;
Embodiment:
The described inside of the utility model adds the brake block that attaches special steel silk screen warning device, shown in Fig. 1-2, comprise brake block body 1, finer wire net 2, heat sensitive sensor 3, lead 4.Through the single-chip microcomputer acknowledge(ment) signal, and the control tutorial light, alarm sends corresponding action.
When just wearing and tearing took place brake block, sensor topmost touched brake disc at first, and signal is sent on the single-chip microcomputer, demonstrates the abrasion condition of brake block friction material.Along with the brake block increase of service time, constantly aggravation of the friction material of brake block wearing and tearing, sensor in different positions provides corresponding altitude signal; When the sensor of the bottom touched brake disc, control circuit was through the Single-chip Controlling alarm equipment alarm.The thickness of the friction material of brake block has reached critical thickness at this moment, needs to change brake block; When the friction material thickness of brake block during less than critical thickness, can will reduce the stopping power of automobile greatly because the distance of brake block and brake disc is excessive, should in time change brake block.
Claims (3)
1. one kind adds the brake block that attaches steel wire, it is characterized in that: the inner finer wire net warning device that embeds is wired on the single-chip microcomputer.
2. a kind of brake block that attaches steel wire that adds according to claim 1 is characterized in that described finer wire is equipped with heat sensitive sensor on the net, the degree of wear that the sensor in different positions representative is different.
3. a kind of brake block that attaches steel wire that adds according to claim 2 is characterized in that in the described heat sensitive sensor, the sensor of the bottom is connected on the warning device.
