Description

Technical Field

[0001] This utility model belongs to the field of rubber diaphragm technology, specifically relating to an auxiliary structure for quick positioning and installation of rubber diaphragms for automotive brake cylinders. Background Technology

[0002] In a braking system, seals typically prevent brake fluid leakage while transmitting pressure. In the master cylinder or wheel cylinder, when the brake pedal is depressed, hydraulic fluid is propelled, and a rubber diaphragm may act as a seal during piston movement, maintaining pressure and preventing air from entering the system. Damage to this diaphragm can lead to brake failure or brake fluid leakage, affecting braking performance.

[0003] In terms of materials, the rubber diaphragm needs to be resistant to high temperatures, oil, and corrosion, because brake fluid is usually corrosive and high temperatures are generated during braking. Common materials may include nitrile rubber (NBR) or fluororubber (FKM), which perform well in high-temperature and oily environments.

[0004] Damage to the rubber diaphragm can cause a series of problems in a car, such as soft brakes, oil leaks, and increased brake pedal travel. Therefore, the rubber diaphragm needs to be replaced regularly. When installing the rubber diaphragm, it is necessary to ensure that the diaphragm's sealing performance meets the requirements, which requires repeated testing and adjustments. The installation process is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-positioning and installation auxiliary structure for automotive brake cylinder rubber diaphragms, thereby solving the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: It includes an installation mechanism disposed on a lip, wherein the diaphragm is disposed in a wavy shape within the lip from the center;

[0006] The mounting mechanism includes a mounting ring fixed to the outside of the lip, an annular positioning piece on the side of the mounting ring facing the lip, the positioning piece passing through the lip, a fixing block at the end of the positioning piece, and sealing rings on both the upper and lower surfaces of the mounting ring.

[0007] It should be noted in the solution that the inner and outer walls of the mounting ring are provided with a plurality of second sealing rings, and the second sealing rings are fixedly connected to the mounting ring.

[0008] It should be noted in the solution that the lip is fixedly connected to the mounting ring, as well as the positioning piece and fixing block on the mounting ring, and the mounting ring, positioning piece and fixing block are integrally formed.

[0009] Compared with the prior art, the quick positioning and installation auxiliary structure for automotive brake cylinder rubber diaphragms provided by this utility model has at least the following beneficial effects:

[0010] (1) By setting the installation mechanism, in actual use, an installation groove is set on the housing of the brake chamber. The installation ring is matched with the installation groove and installed into the installation groove to facilitate the installation of the diaphragm. The sealing ring on the installation ring enters the installation groove at the same time to fill the gap between the installation ring and the installation groove, thereby enhancing the overall airtightness. The diaphragm is installed between the outer shell of the brake chamber and the installation cover, and the outer shell of the brake chamber and the installation cover are fixed. When the diaphragm is deformed by air pressure, since the installation ring, positioning piece and fixing block are made of metal, they are not easily deformed under force and play a supporting role. After the diaphragm is deformed under force, it can return to its initial state to ensure the airtightness of the diaphragm.

[0011] (2) By setting the second sealing ring, the mounting ring is installed into the mounting groove, and the second sealing ring enters the mounting groove at the same time, filling the gap between the mounting ring and the mounting groove, further enhancing the overall airtightness.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 The auxiliary structure for quick positioning and installation of rubber diaphragm for automotive brake cylinders includes a diaphragm 1 and a lip 5 disposed on the outer side of the diaphragm 1.

[0018] In the existing technology, the brake diaphragm is made of rubber, and fibers are added to the rubber to increase its strength. Because the rubber brake diaphragm needs to have very high elasticity, compression deformation and wear resistance, the rubber brake diaphragm is made thicker, which makes the cup body edge extremely inconvenient to install.

[0019] Furthermore, referring to Figure 1-3As shown, it is worth noting that the device also includes an installation mechanism on the lip 5. The membrane 1 is arranged in a wave-like shape inside the lip 5 from the center. The installation mechanism includes an installation ring 6 fixed to the outside of the lip 5. The side of the installation ring 6 facing the lip 5 is provided with an annular positioning piece. The positioning piece passes through the lip 5. The end of the positioning piece is provided with a fixing block. The upper and lower surfaces of the installation ring 6 are provided with sealing rings 7. The installation ring 6, the positioning piece and the fixing block are made of metal.

[0020] With the installation mechanism in place, an installation groove is provided on the housing of the brake chamber during actual use. The installation ring 6 is matched with the installation groove and installed into the installation groove to facilitate the installation of the diaphragm 1. At the same time, the sealing ring 7 on the installation ring 6 enters the installation groove to fill the gap between the installation ring 6 and the installation groove, thereby enhancing the overall airtightness. The diaphragm 1 is then installed between the outer shell of the brake chamber and the installation cover, thus fixing the outer shell of the brake chamber and the installation cover. When the diaphragm 1 deforms under air pressure, the installation ring 6, the positioning piece, and the fixing block are made of metal and are not easily deformed under force, thus providing support. After the diaphragm 1 deforms under force, it can return to its initial state, ensuring the airtightness of the diaphragm 1.

[0021] Furthermore, referring to Figure 1-3 As shown, it is worth noting that the inner and outer walls of the mounting ring 6 are provided with a plurality of second sealing rings 8, and the second sealing rings 8 are fixedly connected to the mounting ring 6.

[0022] By setting the second sealing ring 8, the mounting ring 6 is installed into the mounting groove. At the same time, the second sealing ring 8 enters the mounting groove, filling the gap between the mounting ring 6 and the mounting groove, further enhancing the overall airtightness.

[0023] Furthermore, referring to Figure 1-3 As shown, it is worth noting that the lip 5 is fixedly connected to the mounting ring 6 and the positioning piece and fixing block on the mounting ring 6, and the mounting ring 6, the positioning piece and the fixing block are integrally formed;

[0024] With the installation ring 6, during production, the installation ring 6, positioning piece and fixing block are mass-produced by mold and integrally formed. Then, the installation ring 6, positioning piece and fixing block are fixedly connected to the lip 5 through the vulcanization process.
