Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shock absorber technology, and more specifically, it relates to a spring disc for automotive shock absorbers. Background Technology
[0002] Shock absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shocks, as well as impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride comfort of the vehicle. When driving over uneven roads, the shock-absorbing springs can filter out road vibrations, but the springs themselves will still have reciprocating motion. Shock absorbers are used to suppress the spring bounce.
[0003] The existing shock absorber's damping spring disc cannot use springs made by directly twisting spring steel. It requires additional processing of the spring support coils, which is costly. Furthermore, when the spring is damaged, a specific pre-processed spring needs to be found to replace it, making repairs inconvenient.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a spring disc for automobile shock absorbers in order to achieve a more practical purpose. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a spring disc for automotive shock absorbers, which solves the problem that the existing shock absorber damping spring disc cannot directly use spring steel made by twisting, but requires the upper and lower ends of the spring to be made horizontal, which is costly, and when the spring is damaged, it is necessary to find a specific processed spring, which is inconvenient for repair.
[0006] The purpose and function of this utility model for a spring disc in an automotive shock absorber are achieved by the following specific technical means:
[0007] A spring disc for an automotive shock absorber includes an upper tray and a lower tray, with a spring engaged between the upper tray and the lower tray. Both the upper tray and the lower tray have through holes at their centers. The edges of the upper tray and the lower tray are rolled inward to form rolled edges, and the rolled edges are provided with inclined surfaces. The two ends of the spring are engaged inside the inclined surfaces.
[0008] Furthermore, multiple notches are made on the rolled edge of the lower tray.
[0009] Furthermore, an annular gasket of the same shape as the upper tray is provided on the inner side of the upper tray.
[0010] Furthermore, the lower tray is shaped like a crooked-mouth funnel.
[0011] Furthermore, the upper tray has a concave center, and a support cap is fitted into the concave bottom of the upper tray.
[0012] Furthermore, a sleeve is provided at the bottom through hole of the lower tray, and the sleeve has multiple small notches, and a connecting cylinder passes through the bottom of the lower tray.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The beveled edges on the upper and lower trays allow for a tight wrapping of the spring. Springs made by directly bending and rolling steel bars can be used in conjunction with this design. Springs manufactured using standard processes can be installed without the need to increase the number of spring support coils, making it convenient and inexpensive. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] Example:
[0025] As attached Figure 1 To be continued Figure 4 As shown:
[0026] This utility model provides a spring disc for an automotive shock absorber, including an upper tray 1 and a lower tray 2. A spring 3 is held between the upper tray 1 and the lower tray 2. The edges of the upper tray 1 and the lower tray 2 are rolled inward to form rolled edges 4. The rolled edges 4 are used to hold the upper and lower ends of the spring 3. An inclined surface 5 is provided on the rolled edge 4. The two ends of the spring 3 are held inside the inclined surface 5. The angle formed by the inclined surface 5 allows the rolled edge 4 to cover more area of the spring 3, making it more stable.
[0027] The lower tray 2 has multiple notches 201 on its rolled edge. The notches 201 can reduce the size of the package and trap the spring 3 when the rolled edge 4 shrinks inward.
[0028] Both the upper and lower trays have through holes in their centers for mounting shock absorbers. The upper tray 1 has a recess 101, and a support cap 7 is fitted into the recess at the bottom of the upper tray. The lower end of the support cap 7 is connected to the movable rod of the shock absorber to protect the upper tray 1 and prevent damage to the upper tray 1 during the movement of the movable rod, thus acting as a bearing.
[0029] The upper tray 1 has an annular pad 6 of the same shape as the upper tray 1 on its outer edge. The annular pad 6 is used to place between the spring 3 and the upper tray 1 to protect the upper tray 1 from wear during the movement of the spring 3 and to extend the service life of the upper tray 1.
[0030] The lower tray has a sleeve 202 at the bottom through hole, and the sleeve 202 has multiple small notches 203. A connecting cylinder 8 passes through the bottom of the lower tray 2, and a shock absorber is sleeved in the middle of the connecting cylinder 8. The shock absorber rotates with the left and right rotation of the wheel. The connecting cylinder 8 protects the shock absorber and the lower tray 2, avoids wear between the shock absorber and the lower tray 2, and extends the service life of the shock absorber and the lower tray 2. In addition, when the moving rod of the shock absorber is compressed downward, the connecting cylinder 8 simultaneously restricts the lowest point of cylinder compression, preventing the cylinder from being over-compressed.
[0031] More preferably, the lower tray 2 is in the shape of a crooked funnel. Since the rolled edge 4 is provided with a sloping surface 5, it needs to be set in a crooked form to keep it coaxial with the upper tray 1.
[0032] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
