Description

Technical Field

[0001] This utility model relates to the field of brake chamber technology, and in particular to a diaphragm brake chamber assembly. Background Technology

[0002] A diaphragm brake chamber is a key component in an air braking system that converts the pressure energy of compressed air into mechanical thrust, thereby driving the brake (usually the camshaft or adjusting arm of the wheel brake) to generate braking torque. It is primarily used in commercial vehicles such as trucks and buses. Its core structure includes a metal housing consisting of two interlocking halves, a flexible diaphragm made of high-strength rubber (usually sandwiched between the halves), a push rod (or push disc) connecting to the brake, and a powerful return spring.

[0003] When installing existing brake chambers, two outer shells are usually used and fixed together with bolts. However, aligning the two outer shells is inconvenient, making it difficult for workers to fix the bolts. At the same time, fixing the diaphragm is also troublesome and cannot meet the needs of workers. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A diaphragm brake chamber assembly, comprising:

[0006] The housing consists of two outer shells, Outer Shell 1 and Outer Shell 2, which are connected by multiple bolts. Outer Shell 1 has an air inlet. Outer Shell 2 has a sliding push block. The push block and Outer Shell 2 are together fixedly mounted with a spring. Outer Shell 1 has multiple extension blocks, each with a slot. A limiting block is slidably connected within the slot. The limiting block and the slot are together fixedly mounted with a spring. Outer Shell 2 has a positioning port that matches the extension blocks. The extension blocks are slidably connected within the positioning port. The positioning port has a fixing port. The limiting block is slidably connected within the fixing port. A fixing component is installed inside Outer Shell 2.

[0007] Preferably, the fixing component includes a diaphragm body with multiple mounting ports, and the outer shell has a sliding groove that matches the mounting ports. A mounting block is slidably connected in the sliding groove and is slidably connected in the mounting port. A control mechanism for controlling the movement of the mounting block is installed in the sliding groove.

[0008] Preferably, the control mechanism includes an opening in the slide groove, a reset plate is slidably connected in the opening, the reset plate is fixedly connected to the mounting block, and a spring is fixedly installed on the reset plate and the opening together.

[0009] Preferably, a plurality of temperature sensors are fixedly installed inside the outer casing.

[0010] Preferably, the outer shell has multiple limiting grooves, and the pushing block is fixedly installed with a limiting block that matches the limiting groove, and the limiting block is slidably connected in the limiting groove.

[0011] Preferably, the front end of the limiting block is round, and the fixing opening is also round, with the limiting block matching the fixing opening.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By aligning the extension block on outer shell one with the positioning port on outer shell two, outer shell one and outer shell two can be initially positioned. Then, by sliding the limiting block into the fixing port, the initial fixing of outer shell one and outer shell two can be completed, which can then facilitate the bolt fixing by the staff and improve work efficiency.

[0014] 2. The extension block slides into the positioning port and squeezes the mounting block in the slide groove, causing the mounting block to slide in the slide groove until it enters the installation port, thus completing the installation of the diaphragm body. When disassembly is required, the outer shell 1 and outer shell 2 are separated, and the mounting block slides out of the installation port under the action of spring 3, which facilitates disassembly by the staff and meets the staff's usage needs.

Detailed Implementation

[0020] Reference Figure 1-4 A diaphragm brake chamber assembly, comprising:

[0021] The outer shell 1 and the outer shell 2 are connected by multiple bolts. The outer shell 1 has an air inlet 3. The outer shell 2 has a sliding push block 4. The push block 4 and the outer shell 2 are fixedly installed with a spring 5. The outer shell 1 has multiple extension blocks 6. Each extension block 6 has a slot 7. A limiting block 8 is slidably connected in the slot 7. The limiting block 8 and the slot 7 are fixedly installed with a spring 9. The outer shell 2 has a positioning port 10 that matches the extension block 6. The extension block 6 is slidably connected in the positioning port 10. The positioning port 10 has a fixing port 15. The limiting block 8 is slidably connected in the fixing port 15. The outer shell 2 has a fixing component installed inside.

[0022] By aligning the extension block 6 of outer shell 1 with the positioning port 10 on outer shell 2 and pushing the extension block 6 in, the initial positioning of outer shell 1 and outer shell 2 can be completed. During this process, the limiting block 8 is first squeezed by the positioning port 10 and retracts into the slot 7 until the extension block 6 is pushed to the bottom. At this time, the slot 7 corresponds to the fixing port 15. The limiting block 8 is subjected to the elastic force of spring 2 9 and slides into the fixing port 15, thereby completing the initial fixed installation of outer shell 1 and outer shell 2. Then, the workers can fix the two with bolts.

[0023] The fixing component includes a diaphragm body 11, which has multiple mounting ports 12. The outer shell 2 has a sliding groove 13 that matches the mounting ports 12. A mounting block 14 is slidably connected in the sliding groove 13. The mounting block 14 is slidably connected in the mounting port 12. A control mechanism for controlling the movement of the mounting block 14 is installed in the sliding groove 13.

[0024] When the mounting block 14 is squeezed, it slides in the groove 13 until it enters the mounting port 12 of the diaphragm body 11, thereby completing the quick installation of the diaphragm body 11.

[0025] The control mechanism includes an opening 16 in the slide groove 13, a reset plate 17 is slidably connected in the opening 16, the reset plate 17 is fixedly connected to the mounting block 14, and a spring 18 is fixedly installed on the reset plate 17 and the opening 16 together.

[0026] When the extension block 6 slides into the positioning port 10, the mounting block 14 in the slide groove 13 is squeezed by the extension block 6. Therefore, the mounting block 14 will slide in the slide groove 13 and enter the mounting port 12. When disassembling, the extension block 6 leaves the positioning port 10, and the mounting block 14 and the reset plate 17 are subjected to the elastic force of the spring 18. At this time, the mounting block 14 retracts and leaves the mounting port 12, which makes it convenient for the staff to carry out disassembly work.

[0027] Multiple temperature sensors 19 are fixedly installed inside the outer casing 2. The temperature sensors 19 are existing technology and are infrared sensors. They sense the temperature and send the signal to the controller for regulation and detection. The temperature sensors 19 can quickly determine whether the spring 5 is damaged. Multiple limiting grooves 20 are opened inside the outer casing 2. Limiting blocks that match the limiting grooves 20 are fixedly installed on the pushing block 4. The limiting blocks are slidably connected in the limiting grooves 20. Through the limiting blocks and the limiting grooves 20, the pushing block 4 can slide stably. The front end of the limiting block 8 is round, and the fixing opening 15 is also round. The limiting block 8 matches the fixing opening 15. The matching of its round shape allows the limiting block 8 to quickly enter the slot 7 after being squeezed.

[0028] In this invention, the working principle is as follows: By aligning the extension block 6 of outer shell 1 with the positioning opening 10 on outer shell 2 and pushing the extension block 6 in, the initial positioning of outer shell 1 and outer shell 2 can be completed. During this process, the limiting block 8 is first squeezed by the positioning opening 10, and the limiting block 8 retracts into the slot 7 until the extension block 6 is pushed to the bottom. At this time, the slot 7 corresponds to the fixing opening 15, and the limiting block 8 is subjected to the elastic force of spring 9, and the limiting block 8 slides into the fixing opening 15, thereby completing the initial fixing of outer shell 1 and outer shell 2. The installation block 14 is installed by means of bolts, and the installation block 14 slides in the groove 13 when it is compressed. When the extension block 6 slides into the positioning port 10, the installation block 14 in the groove 13 is compressed by the extension block 6. Therefore, the installation block 14 will slide in the groove 13 and enter the installation port 12. When disassembling, the extension block 6 leaves the positioning port 10, and the installation block 14 and the reset plate 17 are subjected to the elastic force of the spring 18. At this time, the installation block 14 retracts and leaves the installation port 12, which makes it convenient for the staff to carry out the disassembly work.
