Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive brake pad technology, and in particular to an automotive brake pad that is easy to install. Background Technology
[0002] Automotive brake pads, also known as brake linings, are friction materials fixed to the brake drum or brake disc that rotates with the wheel. The friction linings and friction blocks bear external pressure and generate friction to achieve the purpose of vehicle deceleration. Automotive brake pads are generally composed of a steel plate, an adhesive heat insulation layer, and friction blocks. The steel plate needs to be coated to prevent rust. The coating process uses an SMT-4 oven temperature tracker to detect the temperature distribution during the coating process to ensure quality. In order to detect excessive wear of automotive brake pads in time and replace them, an easy-to-install automotive brake pad is needed. Utility Model Content
[0003] The purpose of this invention is to provide a convenient-to-install automotive brake pad to solve the problem mentioned in the background art of timely detection and replacement of excessively worn automotive brake pads.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a conveniently installed automotive brake pad, comprising a brake pad body, the brake pad body comprising an abrasive, a steel backing, and a noise-reducing plate, the steel backing being disposed on one side of the abrasive, the noise-reducing plate being disposed on one side of the steel backing, a heat dissipation groove being formed on one side of the abrasive, a warning spring being provided on one side of the steel backing, a pre-connection mechanism being provided at the connection between the warning springing and the steel backing, the pre-connection mechanism comprising an installation groove, a protrusion, a threaded hole, a connecting block, a groove, a second pin hole, and a bolt, an installation groove being formed on one side of the steel backing, a protrusion being integrally formed on the inner wall of the installation groove, a threaded hole being formed on the inner side of the installation groove, a connecting block being inserted into the inner side of the installation groove, grooves being formed on both sides of the connecting block, a second pin hole being formed through the outer side of the connecting block, and a bolt being inserted into the inner side of the second pin hole.
[0005] Preferably, two protrusions are provided, and the outer wall of the protrusion fits against the inner wall of the groove.
[0006] Preferably, the connecting block is slidably inserted into the mounting slot.
[0007] Preferably, the inner wall of the mounting groove fits against the outer wall of the connecting block.
[0008] Preferably, the warning spring is integrally formed on one side of the connecting block.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This easy-to-install car brake pad allows customers to choose whether to install a warning spring according to their needs. When installing the warning spring, the connecting block at one end of the warning spring is inserted into the mounting groove, so that the protrusion and the groove interlock, which has the effect of limiting and preventing dislodgement. Then, the bolt is inserted into the second pin hole and screwed into the threaded hole to install and fix the warning spring. When the abrasive wears out severely, the warning spring will contact the brake disc and make noise to remind the driver to replace the brake pads, preventing the abrasive from running out and further damaging the brake disc. Moreover, the brake pads can be directly inserted into the calipers for easy installation. Attached Figure Description

[0017] Example
[0018] Please see Figure 1-4This utility model discloses a conveniently installed automotive brake pad, comprising a brake pad body, which includes an abrasive 1, a steel backing 2, and a noise-reducing plate 3. The steel backing 2 is disposed on one side of the abrasive 1, and the noise-reducing plate 3 is disposed on one side of the steel backing 2. A heat dissipation groove 4 is formed on one side of the abrasive 1, and a warning spring 10 is disposed on one side of the steel backing 2. A pre-connection mechanism is provided at the connection between the warning spring 10 and the steel backing 2. The pre-connection mechanism includes an installation groove 5, a protrusion 6, a threaded hole 7, a connecting block 8, a groove 9, a second pin hole 11, and a bolt 12. An installation groove 5 is formed on one side of the steel backing 2, and a protrusion 6 is integrally formed on the inner wall of the installation groove 5. A threaded hole 7 is formed on the inner side of the installation groove 5, and a connecting block 8 is inserted into the inner side of the installation groove 5. Grooves 9 are formed on both sides of the connecting block 8. A second pin hole 11 is provided on the outer side, and a bolt 12 is inserted into the inner side of the second pin hole 11. When installing the car brake pads, a warning spring 10 can be added according to the customer's needs. When installing the warning spring 10, the connecting block 8 at one end of the warning spring 10 is inserted into the mounting groove 5, so that the protrusion 6 and the groove 9 are interlocked, which has the effect of limiting and preventing dislodgement. Then, the bolt 12 is inserted into the second pin hole 11 and screwed into the threaded hole 7, thereby installing and fixing the warning spring 10. When the abrasive 1 is severely worn, the warning spring 10 will contact the brake disc and make noise to remind the driver to replace the brake pads, preventing the abrasive 1 from running out and further damaging the brake disc. When installing the brake pads, they can be directly inserted into the caliper for easy installation. The setting of the heat dissipation groove 4 can increase the heat dissipation surface and better dissipate heat.
[0019] To facilitate the installation of the warning spring 10, two protrusions 6 are provided. The outer wall of the protrusion 6 fits into the inner wall of the groove 9, achieving a pre-fixing effect.
[0020] To facilitate the installation of the warning spring 10, the connecting block 8 is slidably inserted into the mounting slot 5.
[0021] To facilitate the installation of the warning shrapnel 10, the inner wall of the mounting groove 5 is fitted to the outer wall of the connecting block 8.
[0022] To facilitate the installation of the warning spring 10, the warning spring 10 is integrally formed on one side of the connecting block 8.
[0023] Working principle: When installing car brake pads, depending on customer needs, a warning spring 10 can be added. When installing the warning spring 10, the connecting block 8 at one end of the warning spring 10 is inserted into the mounting groove 5, so that the protrusion 6 and the groove 9 interlock, which has the effect of limiting and preventing dislodgement. Then, the bolt 12 is inserted into the second pin hole 11 and screwed into the threaded hole 7, thereby installing and fixing the warning spring 10. When the abrasive 1 is severely worn, the warning spring 10 will contact the brake disc and make noise, reminding the driver to replace the brake pads, preventing the abrasive 1 from running out and further damaging the brake disc. When installing the brake pads, they can be directly inserted into the caliper for easy installation. The car brake pad model is: D1147.
