Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake devices, in particular to a high-sealing multi-chamber spring brake air chamber. Background Art

[0002] The brake chamber refers to a braking system component used in automobiles or other mechanical equipment. The brake chamber can use air pressure to achieve vehicle braking. The compressed gas in the high-sealed multi-chamber spring brake chamber has a high degree of sealing to ensure the continuity of gas energy release. The multi-chamber design can improve the braking stability and braking efficiency of the brake chamber to ensure efficient and reliable braking function of the high-sealed multi-chamber spring brake chamber.

[0003] The existing technology often has the following problems when used:

[0004] The intake pipe of the brake air chamber is usually fixed on the brake air chamber. When the brake air chamber is used frequently and attempted, a lot of dust will accumulate inside the intake pipe. The setting of the fixed structure of the intake pipe will make it difficult to disassemble and clean the intake pipe, resulting in high subsequent maintenance costs for the brake air chamber intake pipe. In addition, a sealing ring is usually provided at the connection between the brake air chamber and the intake pipe, and the sealing ring will produce slight deformation after long-term use. This deformation will reduce the sealing at the air inlet of the brake air chamber, so that the brake air chamber's own sealing performance is weakened. Utility Model Content

[0010] Furthermore, the sealing gasket is a conical sealing gasket whose depth and thickness change linearly, and the outer diameter of the air intake pipe is equal to the inner diameter of the sealing gasket.

DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 4 As shown, the embodiment of the utility model proposes a high-sealing multi-chamber spring brake air chamber, including a brake air chamber body 1, a mounting plate 2, an air intake pipe assembly and an air intake sealing assembly: two air intake ports are provided on the circumferential side wall of the brake air chamber body 1, and sealing gaskets 3 are provided at the two air intake ports, and the sealing gaskets 3 are conical sealing gaskets with a linearly varying depth and thickness; the air intake pipe assembly and disassembly assembly includes two air intake pipes 9 fixedly connected to the mounting plate 2, and the outer diameter of the air intake pipe 9 is equal to the inner diameter of the sealing gasket 3, a mounting screw 4 is rotatably connected to the middle part of the mounting plate 2, and a knob 12 is fixedly connected to the end of the mounting screw 4 away from the brake air chamber body 1, a locking threaded barrel 5 is fixedly connected to the outer wall of the brake air chamber body 1, and the mounting screw 4 and the locking threaded barrel 5 are matched, a positioning guide rod 10 is fixedly connected to the outer wall of the brake air chamber body 1, and a positioning hole 11 is provided on the mounting plate 2, and the positioning guide rod 10 matches the positioning hole 11;

[0025] The positioning holes 11 on the mounting plate 2 are correspondingly plugged into the positioning guide rods 10 on the outer wall of the brake air chamber body 1 to complete the rapid positioning of the mounting plate 2 and the air intake pipe 9, so that the mounting screw 4 and the locking threaded tube 5, and the air intake pipe 9 and the air intake port correspond synchronously, and then the mounting screw 4 is driven to rotate by turning the knob 12, so that the mounting screw 4 and the locking threaded tube 5 are gradually fixed, and the air intake pipe 9 is gradually connected to the air intake port, i.e., the inner side of the sealing gasket 3, so that the mounting plate 2 and the air intake pipe 9 are installed and fixed on the brake air chamber body 1, and by providing a detachable mounting plate 2 and air intake pipe 9, the air intake pipe 9 can be easily disassembled and cleaned, thereby reducing the subsequent maintenance cost of the brake air chamber air intake pipe.

[0026] like Figure 1 and Figure 3 As shown, the air intake sealing assembly includes a sliding rod 6 fixedly connected to the mounting plate 2, a sealing gasket pressing plate 7 is slidably connected to the sliding rod 6, two pressing fins 13 are arranged on the sealing gasket pressing plate 7, and the pressing fins 13 are arranged in an arc-shaped structure, a compression spring 8 is sleeved on the outer wall of the sliding rod 6, and the upper and lower ends of the compression spring 8 are respectively fixedly connected to the mounting plate 2 and the sealing gasket pressing plate 7, and a plurality of limiting rods 14 are fixedly connected to the mounting plate 2, and the sealing gasket pressing plate 7 is in contact with the outer wall of the limiting rod 14;

[0027] When the sealing gasket pressure plate 7 presses the sealing gasket 3, the compression spring 8 can be in a compressed state. After the installation of the mounting plate 2 and the intake pipe 9 is completed, the compression spring 8 uses its own elastic potential energy to push the sealing gasket pressure plate 7 downward, so that the two arc-shaped pressing fins 13 elastically press the sealing gasket 3 at the air inlet, thereby maintaining the sealing performance of the sealing gasket 3 after deformation and improving the sealing performance at the air inlet of the brake air chamber.

[0028] The detailed working process of the utility model is as follows:

[0029] 1. When the brake air chamber body 1 is installed and used, firstly, the positioning hole 11 on the mounting plate 2 is correspondingly plugged with the positioning guide rod 10 on the outer wall of the brake air chamber body 1 to complete the rapid positioning of the mounting plate 2 and the air inlet pipe 9, so that the mounting screw 4 and the locking threaded barrel 5, the air inlet pipe 9 and the air inlet port are synchronously corresponding, and then the mounting screw 4 is driven to rotate by turning the knob 12, so that the mounting screw 4 and the locking threaded barrel 5 are gradually fixed, and the air inlet pipe 9 is gradually connected to the air inlet, that is, the inner side of the sealing gasket 3, so that the mounting plate 2 and the air inlet pipe 9 are installed and fixed on the brake air chamber body 1. By providing a detachable mounting plate 2 and the air inlet pipe 9, the air inlet pipe 9 can be easily disassembled and cleaned, thereby reducing the subsequent maintenance cost of the brake air chamber air inlet pipe;

[0030] 2. During the installation of the mounting plate 2 and the intake pipe 9, the sealing gasket pressure plate 7 is in a state of pressing the sealing gasket 3, that is, the compression spring 8 is in a compressed state. After the installation of the mounting plate 2 and the intake pipe 9 is completed, the compression spring 8 uses its own elastic potential energy to push the sealing gasket pressure plate 7 downward, so that the two arc-shaped pressing fins 13 elastically press the sealing gasket 3 at the air inlet, thereby maintaining the sealing performance of the sealing gasket 3 after deformation and improving the sealing performance at the air inlet of the brake air chamber.
