Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, in particular to an air spring positioning cover plate. Background Art
[0002] A spring that is filled with compressed air in a retractable closed container and utilizes the elastic effect of air is called an air spring. The end structures of existing air springs can be divided into three categories according to the connection method: one is a fixed flange connection type, in which the edge dimensions of both ends of the air spring are equal to or slightly smaller than the maximum outer diameter of the curved bladder, and after drilling several holes, the air spring is fastened with a flange ring and an end plate; the other is a slip-on flange connection type, in which the edge dimensions of both ends of the air spring are much smaller than the maximum outer diameter of the curved bladder, and no holes need to be drilled. The air spring is fastened with a special flange ring and an ordinary end plate, i.e., a positioning cover plate; the third is a self-sealing type, which does not require a flange connection, but is pressed into an end plate and sealed by itself when filled with compressed air.
[0003] Traditional air spring positioning covers all have exhaust holes connected to the inner chamber of the air spring. Sand and foreign matter can easily enter the air spring and the shock absorber piston through the exhaust holes, causing wear on the piston cylinder on the air spring and reducing its life. Utility Model Content
[0004] In order to solve the technical problems existing in the background technology, the utility model proposes an air spring positioning cover plate.
[0005] The utility model provides an air spring positioning cover plate, which comprises a cover plate body and a filter screen. The cover plate body is provided with a through hole which is communicated with a chamber in an air spring installed on the cover plate body, and the filter screen is installed in the through hole.
[0006] Preferably, the top wall of the cover body is inclined downward from the center to the outside, and the top wall of the filter screen located in the through hole is coplanar with the top wall of the cover body.
[0007] Preferably, the through hole comprises a flared section and a narrow section, and the filter screen is adapted to be accommodated in the flared section of the through hole.
[0008] Preferably, the filter screen and the cover plate body are detachably connected via screws.
[0009] Preferably, the filter screen and the cover plate body are integrally formed.
[0010] Preferably, the cover plate body has an assembly surface and an assembly hole that can be fixedly connected to the air spring.
[0011] The air spring positioning cover plate proposed by the utility model prevents sand and gravel from entering the interior of the air spring through the through hole through the arranged filter screen, causing wear of the piston cylinder and reducing its service life. In addition, the filter screen and the cover plate body surface are coplanar and inclined, and the sand and gravel accumulated on the surface of the filter screen can move outward under the action of gravity, thereby preventing the sand and gravel from accumulating on the surface of the filter screen for a long time and causing the filter screen to be blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a first cross-sectional schematic diagram of a partial structure of an air spring positioning cover plate proposed by the utility model;
[0014] Figure 3 This is a second cross-sectional schematic diagram of a partial structure of an air spring positioning cover plate proposed by the utility model. DETAILED DESCRIPTION
[0015] Reference Figure 1-2 The utility model proposes an air spring positioning cover plate, comprising a cover plate body 1 and a filter screen 2. The cover plate body 1 is provided with a through hole 11 communicating with a chamber in an air spring installed on the cover plate body 1, and the filter screen 2 is installed in the through hole 11.
[0016] When in use, the cover body 1 is connected to the automobile air spring, and the through hole 11 on the cover body 1 is connected to the air spring chamber for air inlet and outlet. The set filter 2 can prevent the external air from carrying sand and impurities into the air spring chamber through the through hole 11 when the air spring is reset, causing the piston cylinder in the air spring to wear and reduce its service life.
[0017] In the above embodiment, the cover body 1 is installed on the upper end surface of the air spring, and external sand and gravel impurities are easily accumulated on the filter screen 2, causing the filter screen 2 to be blocked. For this reason, the top wall of the cover body 1 proposed by the utility model is inclined downward from its center to the outside, and the top wall of the filter screen 2 located in the through hole 11 is coplanar with the top wall of the cover body 1. When sand and gravel impurities accumulate on the top of the cover body 1 or the top of the filter screen 2, the sand and gravel impurities slide down along the inclined top surface of the cover body 1 or the filter screen 2 under the action of gravity, thereby avoiding the accumulation of sand and gravel impurities. At the same time, in the process of the cover body 1 moving up and down with the air spring, the airflow avoids downward along the cover body 1, and the airflow can give the sand and gravel impurities a downward force, thereby playing a role in cleaning the sand and gravel impurities.
[0018] It should be further explained that the through hole 11 includes a flared section 111 and a narrow section 112, and the filter screen 2 is adapted to be accommodated in the flared section 111 of the through hole 11, as shown in FIG. Figure 2 , Figure 3 .
[0019] In the above embodiment, the filter screen 2 is detachably connected to the cover body 1 by screws, so that the filter screen 2 can be easily replaced when it is damaged.
[0020] In addition, the filter screen 2 can also be formed integrally with the cover body.
[0021] In the above embodiment, the cover plate body 1 has an assembly surface and an assembly hole that can be fixedly connected to the air spring.
[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
