Technical Field

[0001] This utility model specifically relates to an air spring bearing housing. Background Technology

[0002] Air springs are widely used in self-adjusting air suspension systems for commercial vehicles, buses, rail vehicles, machinery, and building foundations. In air spring systems, bearings and bearing housings are key connecting and moving components, working together to ensure that the air spring can rotate, oscillate, or translate while bearing loads.

[0003] The selection of bearings is usually determined based on factors such as the load, speed, and working environment of the air spring. At the same time, different vehicle body models require different bearing housings during the vehicle production process, which leads to low compatibility between the bearings and bearing housings during installation and removal, causing inconvenience to vehicle production and subsequent maintenance and replacement.

[0010] Preferably, the bearing housing is provided with a plurality of snap-fit ​​blocks evenly arranged circumferentially, the snap-fit ​​blocks are L-shaped, and the snap-fit ​​blocks are engaged with the snap-fit ​​parts.

[0011] Preferably, the piston is further connected to a bladder, the bladder is annular and has an inflation cavity inside, one end of the bladder is fixedly connected to a lower base, and a guide cylinder is sleeved on the outside of the bladder. The inner wall of the guide cylinder fits against the bladder and restricts the expansion of the bladder in the radial direction. A lower dust cover is also provided between the guide cylinder and the lower base, and an upper dust cover is connected between the guide cylinder and the piston.

[0012] Preferably, the bearing housing is made of PA66+30%GF or PA6 50%GF.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The connecting ring at the bottom of the bearing housing is inserted into the mounting groove, with its outer surface fitting against the connecting part to compress and fix it in place. Simultaneously, a snap-fit ​​block circumferentially located on the bearing housing engages with the snap-fit ​​part extending into the mounting groove, thus achieving a direct fit and fixation between the bearing housing and the bearing. By changing the way the bearing housing and bearing are connected, installation during production and subsequent disassembly and maintenance are facilitated, while also improving the adaptability of the bearing housing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: an air spring bearing housing, comprising:

[0022] Piston 1, one end of which is provided with a mounting groove 11, and a bearing 2 is connected in the mounting groove 11;

[0023] Bearing housing 3, which is detachably connected to bearing 2.

[0024] The detachable connection between bearing housing 3 and bearing 2 facilitates the assembly and disassembly of the air spring, while also improving the compatibility between bearing housing 3 and bearing 2.

[0025] In this embodiment, the bearing 2 includes a connecting part and a snap-fit ​​part. The connecting part is installed within the mounting groove 11, while the snap-fit ​​part extends outside the mounting groove 11. The bearing 2 is positioned by installing the connecting part within the mounting groove 11.

[0026] In this embodiment, a connecting ring 31 is provided at the bottom end of the bearing seat 3. The connecting ring 31 is inserted into the mounting groove 11, and the outer side of the connecting ring 31 is in contact with the connecting part.

[0027] In this embodiment, the bearing housing 3 is provided with a plurality of snap-fit ​​blocks 32 evenly arranged in the circumferential direction. The snap-fit ​​blocks 32 are "L" shaped and are engaged with the snap-fit ​​part.

[0028] The connecting ring 31 at the bottom of the bearing housing 3 is inserted into the mounting groove 11, and the outer surface of the connecting ring 31 fits against the connecting part, thus pressing and fixing the connecting ring 31. At the same time, the snap-fit ​​block 32 circumferentially provided on the bearing housing 3 engages with the snap-fit ​​part extending into the mounting groove 11, thereby achieving direct engagement and fixation between the bearing housing 3 and the bearing 2. By changing the engagement and connection method between the bearing housing 3 and the bearing 2, installation during production and subsequent disassembly and maintenance are facilitated, while also improving the adaptability of the bearing housing 3.

[0029] In this embodiment, the bearing housing 3 is made of PA66+30%GF or PA6 50%GF, which gives the bearing housing 3 high strength and stability.

[0030] In this embodiment, a bladder 6 is also connected to the piston 1. The bladder 6 is made of elastic material, is annular, and has an inflation cavity inside. One end of the bladder 6 is fixedly connected to the lower base 7, and a guide cylinder 5 is also sleeved on the outside of the bladder 6. The inner wall of the guide cylinder 5 fits against the bladder 6 and restricts the expansion of the bladder 6 in the radial direction. A lower dust cover 8 is also provided between the guide cylinder 5 and the lower base 7, and an upper dust cover 4 is connected between the guide cylinder 5 and the piston 1.

[0031] This air spring features a split structure, consisting of bearing housing 3, bearing 2, and other components. The altered connection between bearing housing 3 and bearing 2 facilitates installation and disassembly; replacing the air spring simply requires opening the top cover. This split, replaceable design makes air spring replacement more convenient, significantly reducing maintenance time and costs. Furthermore, the high-quality materials used in the bearing housing ensure high strength and stability, reliably supporting the air spring's operation. Simultaneously, selecting appropriate bearing configurations helps reduce friction and wear, improving the overall system's reliability and service life. Corresponding replaceable air spring bearing housings are designed and manufactured according to different air spring models and operating requirements, ensuring strong adaptability and versatility in installation and subsequent maintenance.

[0032] This utility model, bearing housing 3, allows for installation on the same machine tool, platform, but different vehicle bodies; only the bearing housing needs to be replaced for air spring adaptation. This bearing housing ensures that the axial force on the bearing is perpendicular to the air spring axis, eliminating lateral force on the axis and absorbing torsion, thus improving its durability. Simultaneously, it allows for adaptation to different vehicle bodies, such as… Figure 4 The diagram shown is a schematic of another type of bearing housing fit and installation.
