Description

Technical Field

[0001] The utility model relates to the field of McPherson air suspension shock absorbers, in particular to a paired McPherson air suspension shock absorber. Background Art

[0002] Most existing McPherson strut shock absorbers are only suitable for single-sided installation, meaning a single shock absorber assembly can only be installed on one side of the vehicle. Because the left and right sides have different connection locations with the suspension stabilizer bar, different shock absorbers are required. This invisibly increases material and parts management costs. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of the present invention is to provide a paired McPherson air suspension shock absorber to simplify the left and right side parts and reduce material management costs.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A paired McPherson air suspension shock absorber includes an air spring sleeved on a hydraulic shock absorber. A wing-type bracket is provided on the outer tube of the shock absorber. The wing-type bracket has a pair of first and second side wings extending in a mirror-image manner. When the shock absorber is in the left installation position or the right installation position, the first side wing or the second side wing is respectively used to connect to the suspension stabilizer bar on the corresponding side.

[0006] In a preferred embodiment of the present invention, an airbag fixing seat is provided on the outer tube, and the airbag base located at the lower end of the air spring is engaged and fixed with the airbag fixing seat.

[0007] In a preferred embodiment of the present invention, a first through-hole is formed on the airbag base, and the shock absorber penetrates into the air spring through the first through-hole.

[0008] In a preferred embodiment of the present invention, a first protrusion is provided on an end surface of the first through-hole, and a notch that matches the first protrusion is provided on the airbag fixing seat.

[0009] In a preferred embodiment of the present invention, the air spring is fixed to the tower top via a cover plate on its top.

[0010] In a preferred embodiment of the present invention, a second through-hole is provided on the cover plate, and the shock absorber passes through the second through-hole, passes through the air spring, and is engaged and fixed to the tower top.

[0011] In a preferred embodiment of the present invention, at least one second protrusion is provided on the end surface of the second through-hole.

[0012] The beneficial effects of the present invention are:

[0013] The paired McPherson air suspension shock absorber provided by the utility model has a paired wing-type bracket arranged on the outer cylinder of the shock absorber, and the other shock absorber has two opposed connecting rod mounting points, so that the shock absorber can match the installation on the other side of the vehicle body after rotating about the axis. When one side of this paired bracket is not used for connection with the connecting rod, it can also be used to fix the air tank of the air spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention.

[0022] As used in this specification, the singular forms "a," "an," "said," and "the" include the plural forms unless otherwise expressly stated. The terms "include," "comprise," and "contain" as used in this specification indicate the presence of the claimed features, but do not exclude the presence of one or more additional features. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0023] In the specification, when an element is referred to as being “on,” “fixed” to, “connected to,” or “engaged to,” etc., another element, the element may be directly on, fixed to, connected to, engaged to, or in contact with the other element, or intervening elements may be present. In the specification, when a feature is arranged “adjacent” to another feature, it may mean that the feature has a portion overlapping with the adjacent feature or a portion located above or below the adjacent feature.

[0024] It will be understood that although the terms "first," "second," etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Thus, a first element may be referred to as a second element without departing from the teachings of the present invention.

[0025] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide many additional embodiments. In all figures, the same reference numerals represent the same elements or elements with the same function.

[0026] Figure 1 The exhibit showcases a McPherson strut air suspension shock absorber, achieved by replacing the coil springs on the original McPherson strut with air springs 2. Considering that this shock absorber is primarily used in commercial vehicles, where precision requirements are relatively low, a modified wing-shaped bracket 14 allows it to be installed on different sides of the vehicle body, reducing material management costs.

[0027] Figures 2 to 4 The main structure of the shock absorber is shown. A wing-shaped bracket 14 is mounted on the outer cylinder 10. This bracket 14 has a first wing 15 and a second wing 16 extending outwards. The first and second wings 15, 16 are mirror images of each other about the center of the bracket 14. Therefore, when the shock absorber 1 is installed on the left side of the vehicle, the first wing 15 is connected to the stabilizer bar. When the shock absorber 1 is installed on the right side of the vehicle, the wing-shaped bracket 14 rotates 180 degrees with the outer cylinder 10, and the second wing 16 is located at the corresponding position of the original first wing 15, thus achieving the same part of the same mounting arrangement.

[0028] Combined with reference Figures 5 and 6The piston rod 17 sequentially passes through the first through-hole 22 at the bottom and the second through-hole 25 at the top of the airbag 20, and is then connected to the tower support 3. The first through-hole 22 is provided on the airbag base 21, and a first protrusion 23 is provided on the end surface of the first through-hole 22. The outer tube 10 is provided with an airbag fixing seat 11 that abuts the end surface of the first through-hole 22, thereby supporting the airbag 20 through the airbag base 21. The airbag fixing seat 11 is provided with a notch 12 corresponding to the first protrusion 23, ensuring that the airbag 20 can be properly assembled. The second through-hole 25 is located on the cover plate 24, and its end surface is also provided with at least one second protrusion 26. In a preferred embodiment, three second protrusions 26 are arranged equally along the circumferential end surface of the second through-hole 25 to achieve installation and positioning with the tower support 3.

[0029] In addition to being used for connecting with the suspension stabilizer bar, the first side wing 15 and the second side wing 16 can also be used to fix the air pipeline of the air spring 2. The double-sided structure provides a larger routing space for the air pipeline.
