Description

Technical Field

[0001] This invention relates to the field of air spring technology, specifically to a detachable upper air chamber structure. Background Technology

[0002] The upper air chamber of an air spring suitable for an external valve shock absorber typically consists of several main parts, including the upper air chamber, top mount, and buffer block. Among them, the top mount and buffer block are frequently replaced with different performance parts during the vehicle performance tuning process to meet the tuning requirements. Therefore, the top mount and buffer parts of the upper air chamber used in the vehicle tuning process can usually be removed separately from the upper air chamber as an independent assembly.

[0003] Traditional air spring upper chambers often integrate the top mount and the buffer block into a single assembly. The top mount is interference-fitted with the mounting base. During the calibration process, the top mount may be difficult to remove from the mounting base, especially for top mounts with a sulfidated metal shell. Therefore, when different top mounts are needed to verify the overall vehicle performance, they need to be grouped according to their performance, and many sets of top mount and mounting base assemblies need to be made. As a result, the traditional upper chamber structure has the disadvantages of high cost of test prototypes and long manufacturing cycle. Summary of the Invention

[0004] To address the technical problems existing in the background art, the present invention proposes a detachable upper air chamber structure.

[0005] The present invention proposes a detachable upper air chamber structure, which is suitable for the air spring of an external valve type shock absorber. Specifically, it includes an air chamber body, a top rubber mounting seat, a top cover, a buffer block mounting seat, a buffer block, and a top rubber. The top rubber mounting seat is detachably installed in the inner cavity of the air chamber body, and the top rubber mounting seat has a through-hole receiving cavity along its axial direction.

[0006] The top adhesive is installed inside the receiving cavity and is interference-fitted with the top adhesive mounting base;

[0007] The top cover is detachably installed at one end of the receiving cavity, and the top cover presses against one side of the top adhesive.

[0008] The buffer block mounting base is installed at the other end of the receiving cavity and is detachably connected to the top adhesive mounting base. The buffer block is installed on the side of the buffer block mounting base away from the top adhesive.

[0009] As a further optimization of the present invention, the top adhesive mounting base is connected to the air chamber body by a first screw.

[0010] As a further optimization of the present invention, the top rubber mounting base and the air chamber body are sealed by a second O-ring.

[0011] As a further optimization of the present invention, the top cover is assembled inside one end of the top adhesive mounting base by a retaining ring, and the top cover is sealed to the inner wall of the top adhesive mounting base by a first O-ring.

[0012] As a further optimization of the present invention, the buffer block mounting base and the top adhesive mounting base are inserted into each other at the end away from the top cover and fastened by a second screw.

[0013] As a further optimization of the present invention, a gap is provided between the buffer block mounting base and the top adhesive to form a disassembly groove.

[0014] The detachable upper air chamber structure proposed in this invention has the following beneficial effects:

[0015] This invention installs the buffer block and the top adhesive in two different mounting bases, allowing for the design of a disassembly groove for the top adhesive at the bottom of the mounting base. When the top adhesive needs to be replaced during the debugging process, it can be pressed out through the disassembly groove for individual disassembly and replacement, eliminating the need to group the top adhesives according to their performance. This reduces the number of mounting bases required and lowers the manufacturing cost and cycle time of the debugging prototype.

[0016] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] Please see Figure 1 A detachable upper air chamber structure is suitable for the air spring of an external valve shock absorber. The top rubber and the buffer block can be replaced separately at the same time. Specifically, it includes an air chamber body (1), a top rubber mounting seat (2), a top cover (3), a buffer block mounting seat (8), a buffer block (9), and a top rubber (11). The top rubber mounting seat (2) is detachably installed in the inner cavity of the air chamber body (1). The top rubber mounting seat (2) has a through-hole cavity along its axial direction.

[0025] The top adhesive (11) is installed in the receiving cavity and is interference-fitted with the top adhesive mounting base (2);

[0026] The top cover (3) is detachably installed at one end of the receiving cavity, and the top cover (3) presses against one side of the top adhesive (11);

[0027] The buffer block mounting base (8) is installed at the other end of the receiving cavity and is detachably connected to the top adhesive mounting base (2). The buffer block (9) is installed on the side of the buffer block mounting base (8) away from the top adhesive (11).

[0028] Specifically, the top rubber mounting base (2) is connected to the air chamber body (1) by the first screw (7), which makes it easy to quickly assemble the top rubber mounting base (2) onto the air chamber body (1) and also makes it easy to disassemble.

[0029] Specifically, the top rubber mounting base (2) and the air chamber body (1) are sealed by a second O-ring (6);

[0030] Furthermore, the outer peripheral surface of the top adhesive mounting base (2) has an annular groove that is compatible with the second O-ring (6). The top adhesive (11) and the top adhesive mounting base (2) are interference-fitted together, and the second O-ring (6) is then assembled in the annular groove to form the top adhesive mounting base assembly.

[0031] Specifically, the top cover (3) is fitted inside one end of the top adhesive mounting base (2) by means of a retaining ring (4), and the top cover (3) is sealed to the inner wall of the top adhesive mounting base (2) by means of a first O-ring (5);

[0032] Furthermore, the outer peripheral surface of the top cover (3) has an annular groove that is adapted to the first O-ring (5), and the first O-ring (5) is assembled in the annular groove for sealing.

[0033] Specifically, the buffer block mounting base (8) is inserted into the end of the top rubber mounting base (2) away from the top cover (3) and fastened by the second screw (10), which makes it easy to quickly assemble the buffer block mounting base (8) onto the top rubber mounting base (2) and also makes it easy to disassemble.

[0034] Specifically, there is a gap between the buffer block mounting base (8) and the top adhesive (11) to form a disassembly groove (2-1), which facilitates pushing the top adhesive (11) upward;

[0035] The detachable upper air chamber structure proposed in this invention is assembled by a top rubber mounting seat (2), a second O-ring (6), and a top rubber (11) to form a top rubber mounting seat assembly. A buffer block mounting seat (8) and a buffer block (9) are assembled to form a buffer block mounting seat assembly. The buffer block mounting seat assembly and the top rubber mounting seat assembly are then connected by a second screw (10) to form a top rubber-buffer block functional component assembly. The top rubber-buffer block functional component assembly is then assembled onto the air chamber body (1) by a first screw (7). Finally, a top cover (3) and a retaining ring (4) are installed. Assemble the upper air chamber assembly and seal the internal chamber of the air chamber with the first O-ring (5) and the second O-ring (6). When it is necessary to adjust the top rubber (11) and the buffer block (9), remove the second screw (10), pull out the buffer block mounting assembly, and push out the top rubber (11) at the disassembly groove (2-1) to realize the quick disassembly and assembly of the top rubber (11) so that the top rubber (11) can be disassembled and replaced separately without grouping according to the performance of the top rubber, thereby reducing the number of mounting bases manufactured and reducing the manufacturing cost and manufacturing cycle of the debugging sample.
