Description

Technical Field

[0001] The utility model relates to the field of automobile shock absorber connection plates, in particular to a shock absorber connection plate. Background Art

[0002] The shock absorber connecting plate, on the automobile shock absorber, usually has an air spring structure as the automobile shock absorber, such as the Chinese utility model patent application number 202221656683.2, the patent name is the bladder detachable connecting plate assembly on the automobile shock absorber, the plate body is in the shape of a cavity 01, and there is also a sandwich cavity 02 inside, and a hollow connecting column is provided on the plate body, the swivel is sleeved on the connecting column, and the connecting column is riveted by a riveting machine, so that the swivel is fixed on the connecting column. In this riveting process, because the riveting machine needs to press the riveting connecting column, because the plate body is in the shape of a cavity, it is easy to cause the plate body to deform. In practice, the scrap rate is relatively high. Utility Model Content

[0003] The purpose of the utility model is to address the deficiencies of the prior art, at least to a certain extent solve the technical problems in the related technology, and provide a shock absorber connecting plate to solve the problem that the plate body is easily deformed and scrapped during press riveting during traditional assembly.

[0004] A shock absorber connecting plate comprises a plate body and a swivel, wherein a connecting column is arranged on the plate body, a cavity is arranged in the swivel, a bearing is fixed in the cavity wall, an inner ring of the bearing is sleeved on the connecting column, the connecting column is connected with a rotating sleeve through a thread, the rotating sleeve contacts the inner ring of the bearing, and the rotating sleeve is welded to the connecting column.

[0005] A limiting groove is arranged in the cavity wall of the swivel, the outer ring of the bearing is interference fit with the groove wall of the limiting groove, and the inner ring of the bearing is interference fit with the outer wall of the connecting column.

[0006] The rotating sleeve comprises a connected threaded portion and a limiting portion, the inner wall of the threaded portion is provided with an internal thread, the connecting column is provided with an external thread adapted to the internal thread, a plurality of grooves are evenly distributed on the limiting portion, and the horizontal distance between the limiting portion and the cavity wall is a spacing.

[0007] The technical effects of the utility model are mainly reflected in the following aspects: the installation is more convenient, with a simple welding process, compared with the transmission riveting process, the disc body is subjected to the pressure of the riveting machine, and because the disc body is hollow and has an interlayer, it is easier to deform. Therefore, the scrap rate of the utility model is greatly reduced compared with the traditional process. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The embodiments of the present invention are described in detail below, which are intended to explain the present invention so as to make the technical solution of the present invention easier to understand and grasp, but should not be construed as limiting the present invention.

[0014] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown: a shock absorber connecting plate, including a plate body 1 and a rotating body 2, a connecting column 3 is arranged on the plate body 1, a cavity 21 is arranged in the rotating body 2, a bearing 4 is fixed in the wall of the cavity 21, the inner ring of the bearing 4 is sleeved on the connecting column 3, the connecting column 3 is connected with a rotating sleeve 5 through a thread, the rotating sleeve 5 abuts against the inner ring of the bearing 4, the rotating sleeve 5 is tightened and forcefully abuts against the inner ring of the fixed column bearing 4, the inner ring of the bearing 4 is locked, and then the rotating body 2 is fixed, the outer ring of the bearing 4 is fixed on the rotating body 2, so that the rotating body 2 and the plate body 1 can rotate relatively, and then the rotating sleeve 5 is welded to the connecting column 3, so that the rotating sleeve 5 and the connecting column 3 form a The body prevents the rotating sleeve 5 from rotating during use, thereby preventing the inner ring of the bearing 4 and the outer wall of the connecting column 3 from axial displacement. Because once axial displacement occurs, although the inner ring of the bearing 4 and the outer wall of the connecting column 3 have an interference fit, the continuous axial displacement will cause wear between the inner ring of the bearing 4 and the outer wall of the connecting column 3, and the inner ring of the bearing 4 cannot be tightly fitted with the outer wall of the connecting column 3. The inner ring of the bearing 4 will rotate idly, and the mechanical wear will be greater. The above structure is more convenient to install, and with a simple welding process, compared with the transmission riveting process, the disc body 1 is subjected to the pressure of the riveting machine and is more easily deformed. Therefore, the scrap rate of the utility model is greatly reduced compared with the traditional process.

[0015] A step hole is provided on the wall of the cavity 21 of the swivel 2. After the bearing 4 is installed in the step hole, the outer ring of the bearing 4 is interference fit with the wall of the step hole, and then the end of the step hole is riveted to form a limiting groove 22. A limiting groove 22 is provided in the wall of the cavity 21 of the swivel 2. The outer ring of the bearing 4 is interference fit with the groove wall of the limiting groove 22, and the inner ring of the bearing 4 is interference fit with the outer wall of the connecting column 3. The outer ring of the bearing 4 is locked in the limiting groove 22. The inner ring of the bearing 4 is interference fit at one end of the connecting column 3 by the disk body 1, and the other end is locked by the rotating sleeve 5, thereby preventing mechanical wear during the rotation of the swivel 2 and the disk body 1.

[0016] The rotating sleeve 5 includes a connected threaded portion 51 and a limiting portion 52. The inner wall of the threaded portion 51 is provided with an internal thread. The connecting column 3 is provided with an external thread that matches the internal thread. The external thread cooperates with the internal thread to lock the rotating sleeve 5 to the inner ring of the bearing 4. The limiting portion 52 is evenly distributed with a plurality of grooves 53. The horizontal distance between the limiting portion 52 and the wall of the cavity 21 has a spacing L. The function of the spacing L is to make a non-standard wrench by yourself. The non-standard wrench includes an annular barrel with a wall thickness slightly smaller than L. A plurality of protrusions that match the grooves 53 are provided in the annular barrel. A handle is provided on the annular barrel, and the rotating sleeve 5 is rotated by using the wrench.

[0017] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
