Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing spring technology, specifically a shock-absorbing spring for a clutch. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Made of elastic material, it deforms under external force and returns to its original shape after the force is removed. It is also called a "spring". They are generally made of spring steel. Springs come in a wide variety of types; according to shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0003] However, existing shock-absorbing springs used for clutches are difficult to install and are prone to displacement during use. Summary of the Invention

[0004] The purpose of this invention is to provide a shock-absorbing spring for a clutch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shock-absorbing spring for a clutch, comprising a spring body, wherein a contact platform is provided at the top and bottom of the spring body, and a plurality of positioning holes are evenly distributed on the surface of the contact platform, the interior of the spring body is a hollow structure, the positioning holes communicate with the interior of the spring body, and limit plates are fixedly connected to the surface of the contact platform on both sides of the positioning holes.

[0006] Preferably, the inner surface of the limiting plate has an arc-shaped opening.

[0007] Beneficial effects

[0008] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0009] 1. This utility model significantly increases the contact area between the spring and the corresponding clutch components by setting contact platforms at the top and bottom of the spring body. This not only effectively reduces the local pressure at the contact points and reduces component wear caused by stress concentration, but also makes the force distribution more uniform and improves the stability of the spring during operation.

[0010] 2. Furthermore, the multiple positioning holes on the contact platform allow for precise positioning and fixation of the spring onto the clutch using bolts, pins, and other fasteners. Simultaneously, the positioning holes communicate with the hollow internal structure of the spring body, avoiding the positioning structure from occupying internal space and allowing for flexible insertion of connecting components according to actual installation needs. This solves the problem of difficult fixation in existing shock-absorbing spring installations, significantly improving installation efficiency and fixation reliability.

[0011] 3. The limiting plates on both sides of the positioning holes on the contact platform surface can provide lateral restraint for the connection between the spring and the clutch. During clutch operation, the limiting plates can prevent the spring from shifting laterally due to vibration, changes in force, etc., ensuring that the spring is always in the preset working position. This effectively solves the problem of easy displacement of existing springs and ensures the normal operation of the clutch. Attached Figure Description

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention 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. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] like Figure 1 This is a schematic diagram of a preferred embodiment of the present invention for a shock-absorbing spring used in a clutch. In this embodiment, the shock-absorbing spring for a clutch includes a helical spring body 1, which is made of spring steel and has a hollow structure. Flat contact platforms 2 are machined at the top and bottom of the spring body 1, respectively. The contact platforms 2 are precision ground to ensure a smooth surface, thereby increasing the contact area with the corresponding clutch components, reducing local pressure, and avoiding wear caused by stress concentration.

[0018] Four positioning holes 3 are evenly distributed on the contact platform 2. These positioning holes 3 are through holes and communicate with the internal hollow structure of the spring body 1. The positioning holes 3 can be used to insert fasteners such as bolts or pins, thereby accurately positioning and firmly installing the spring in the designated position on the clutch. This design avoids occupying the effective internal space of the spring and provides a flexible installation method.

[0019] On both sides of each positioning hole 3, a limiting plate 4 is also fixedly connected. The limiting plate 4 is welded perpendicularly to the contact platform 2, and its inner surface, i.e. the side facing the positioning hole 3, is machined with an arc-shaped opening 41. The curvature of the arc-shaped opening 41 matches that of commonly used fasteners such as bolt heads or sleeve outer walls, which can better accommodate and restrict the connecting parts during installation and prevent them from sliding laterally during operation.

[0020] During installation, the damping spring is placed between the clutch drive plate and the driven plate. Bolts are inserted through the positioning hole 3 and tightened to ensure the contact platform 2 is tightly against the clutch component surface. The limiting plate 4 and its arc-shaped opening 41 effectively constrain the position of the connecting parts, thereby suppressing the lateral displacement of the spring throughout the entire operation and ensuring it remains in the preset working position, guaranteeing the stability and reliability of the clutch operation.

[0021] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
