Description

Drum brake lining wear alarm device

Technical Field

The utility model belongs to the technical field of automobile brake system, especially, a brake lining wear alarm device of external in drum brake's the adjusting arm outside.

Background

With the continuous development of science and technology and the frequent occurrence of driving accidents, the active safety of automobiles is more and more emphasized. With the promulgation and implementation of GB7258-2017 technical conditions for motor vehicle operation safety and JT/T1178.2-2019 technical conditions for commercial truck safety, the development of brake lining (block) abrasion alarm technology is greatly promoted. Various high, medium and low-grade alarm devices are led out endlessly. However, no matter how the change is, the alarm is not a disposable product (such as a grinding-off alarm wire harness) or is an external alarm with high price.

The analysis external-hanging alarm mostly adopts a mechanical toggle switch form or a magnetic code technical form, and has high requirements on sealing performance, relatively complex structure, low price and no competitive advantage.

In addition, the long cable connection from the alarm to the data processor also causes a dilemma that the overall price is high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned prior art not enough, provide an externally hung drum brake lining wear alarm device in drum brake's the adjusting arm outside, including procapsid, back lid, the axial is spacing in the procapsid and can pivoted response piece, be equipped with the wireless module of on-off switch in the procapsid in the installation, two little magnet that can trigger on-off switch of partial installation that the response piece is located the procapsid have a wireless module in the procapsid, can produce magnetic field activation wireless module and send alarm signal to brake lining wearing and tearing when magnet in the response piece rotates relevant position and report to the police, the utility model discloses possess and provide accurate alarming function to brake lining wearing and tearing to people's driving safety's problem has been reduced.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a drum brake lining wearing and tearing alarm device, includes procapsid, back lid, axial spacing in the procapsid and can pivoted response piece, spacing fixed bolt round pin and the thin nut of hexagonal of using, response piece center runs through and is provided with the connecting hole, installs wireless module in the procapsid, be equipped with on-off switch in the wireless module, the part that the response piece is located the procapsid installs two little magnet that can trigger on-off switch, be equipped with convex connection tooth on the connecting hole inner wall, the assembly sign has on the procapsid, have on the response piece can with the installation sign of assembly sign alignment.

And a wireless module is arranged in the front shell, and when the magnet in the induction sheet rotates to a corresponding position, the wireless module can be activated to send an alarm signal to alarm the abrasion of the brake lining.

Further setting, there is the hole of installation magnet in the response piece, and magnet inlays downtheholely, when the response piece rotated, drives magnet synchronous rotation, magnet rotates to the wireless module below and to produce magnetic field activation wireless module and send alarm information.

The utility model has the advantages that: the utility model discloses possessed and provided accurate alarming function to brake lining wearing and tearing to people's driving safety's problem has been reduced.

Drawings

Fig. 1 is an exploded schematic view of the present invention;

fig. 2 is a schematic front view of fig. 1.

In the figure: the sensor comprises a front shell 1, an assembly mark 1a, a small magnet 2, an induction sheet 3, a connecting hole 3a, connecting teeth 3b, an installation mark 3c, a rear cover 4, a wireless module 5, a fixed bolt pin 6 and a hexagonal thin nut 7.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

As shown in fig. 1-2, a drum brake lining wear alarm device is a data processor based on automobile axle end hub bearing temperature monitoring and brake lining wear monitoring, and comprises a front shell 1, a rear cover 4, an induction sheet 3 which is axially limited in the front shell and can rotate, a fixed bolt pin 6 for limiting and a hexagonal thin nut 7, wherein a connecting hole 3a is formed in the center of the induction sheet 3 in a penetrating manner, a wireless module 5 is installed in the front shell 1, an on-off switch is arranged in the wireless module 5, two small magnets 2 which can trigger the on-off switch are installed on the part of the induction sheet 3 located in the front shell 1, convex connecting teeth 3b are arranged on the inner wall of the connecting hole 3a, an assembly mark 1a is arranged on the front shell 1, and an assembly mark 3c which can be aligned with the assembly mark 1a is arranged on the induction sheet 3.

There is a wireless module 5 in procapsid 1, has the hole of installation magnet 2 in the response piece 3, and magnet 2 inlays downtheholely, when response piece 3 rotates, drives magnet synchronous rotation, and when magnet 2 in the response piece 3 rotated 5 below corresponding positions of wireless module, can produce magnetic field activation wireless module 5 and send alarm signal and report to the police to brake lining wearing and tearing.

When the drum brake lining wear alarm device is installed, the induction sheet 3 is connected with one end of a cam shaft of the drum brake through the connecting hole 3a, the connecting teeth 3b on the inner ring of the connecting hole 3a are installed in the tooth part matched with the cam shaft to enable the cam shaft and the induction sheet to form a whole, so that the cam shaft can drive the induction sheet 3 to rotate, the small magnet 2 installed on the induction sheet can trigger an on-off switch when the brake lining of the drum brake is worn to a limit value, the wireless module 5 is activated to send a signal, and the external receiver receives the signal sent by the wireless module 5 and then gives an alarm to remind a driver, so that the problem of driving safety of people is reduced.
