Description

Brake pad alarm sensor

Technical Field

The utility model belongs to the technical field of auto-parts.

Background

The existing brake pad alarm mainly has two modes, the first mode is a simpler mechanical alarm, namely, when the brake pad is worn to expose the alarm, the alarm is rubbed to make a harsh sound. The second type is a sensor type, and under a normal working state, when the sensor is normally opened, the sensor is always a path, and at the moment, no alarm display exists on an instrument panel. When the line of the sensor is broken by abrasion, the line is broken, an alarm display starts on the instrument panel, and the brake system condition of the vehicle owner is prompted, so that the vehicle can be maintained in real time.

When the wheel cylinder is abnormally returned, the brake pad is stuck, and a bearing or a wheel has a fault, the abnormal abrasion of the brake pad can be caused, even the traffic accident can be caused, but the current sensor type alarm can only detect the abnormal abrasion of the brake pad after the brake pad is abraded.

Disclosure of Invention

In order to discover the above-mentioned trouble earlier, just can discover above-mentioned trouble early in breaking down, the utility model provides a brake block alarm sensor, the utility model discloses the technical scheme who adopts specifically as follows:

a brake pad alarm sensor comprises a sensor body 1, a lead wire 2, a metal card 3, a thermocouple 4 and a lead wire protective sleeve 5, wherein the sensor body 1 is wedge-shaped and is divided into three layers, a fixing groove is formed in the middle of the upper layer and the lower layer and used for mounting the lead wire 2, the section of the middle layer is smaller than that of the upper layer and the lower layer and is provided with a plurality of clamping grooves, and the metal card 3 is clamped on the outer side of the middle layer; a through hole is formed in the middle layer, the thermocouple 4 is arranged in the through hole, and the end part of the thermocouple is contacted with the metal card 3; the lead 2 penetrates from the fixing groove of the upper layer and penetrates out from the fixing groove of the lower layer, and the two wire harnesses and the lead 2 of the thermocouple 4 are led out from the rear part of the sensor body and wrapped by the lead protecting sleeve 5.

The utility model has the advantages that:

the thermocouple tip contacts with the metal card, and the joint contacts with the brake block in the mounting groove of brake block when installation of metal card, realizes the real-time supervision to the brake block temperature through metal heat conduction. When the brake pad is abnormally high in temperature, the driver can be prompted, so that the brake pad can be detected and repaired as early as possible, and appropriate measures are taken to reduce accidents.

fig. 2 is a schematic diagram of the structure of the device of the present invention.

Detailed Description

The technical solution of the present invention will be further explained and illustrated in the following embodiments.

As shown in fig. 1 and 2, the brake pad alarm sensor in this embodiment is composed of a sensor body 1, a wire 2, a metal card 3, a thermocouple 4 and a wire protection sleeve 5, wherein the sensor body 1 is wedge-shaped and is divided into three layers, a fixing groove is formed in the middle of the upper layer and the lower layer for mounting the wire 2, the section of the middle layer is smaller than that of the upper layer and the lower layer, and a plurality of clamping grooves are formed in the middle layer, and the metal card 3 is clamped outside the middle layer; a through hole is formed in the middle layer, the thermocouple 4 is arranged in the through hole, and the end part of the thermocouple is contacted with the metal card 3; the lead 2 penetrates from the fixing groove of the upper layer and penetrates out from the fixing groove of the lower layer, and the two wire harnesses and the lead 2 of the thermocouple 4 are led out from the rear part of the sensor body and wrapped by the lead protecting sleeve 5.

The working principle is as follows:

the sensor body 1 of the brake pad alarm sensor is arranged in the mounting groove of the brake pad through the metal clamping piece 3, the upper surface of the sensor body 1 is parallel to the surface of the brake pad, when the brake pad is worn to the limit, the sensor body 1 is made of plastic materials, so that a lead 2 on the upper layer of the sensor body 1 can be quickly worn and broken, and an alarm is given when a circuit is short-circuited;

the thermocouple tip contacts with the metal card, and the joint contacts with the brake block in the mounting groove of brake block when the installation, realizes the real-time supervision to the brake block temperature through metal heat conduction, can indicate the driver when the unusual high temperature appears in the brake block, makes its going to detect and repair as early as possible, realizes the early diagnosis of trouble. The utility model discloses also can indicate the thermal decay of brake block, the driver can take the appearance of suitable measure reduction accident.
