Description

Technical Field

[0001] This utility model relates to the field of spring protection technology, and in particular to an installation structure for protecting springs. Background Technology

[0002] As a key assembly in the automotive transmission system, the clutch is installed between the engine and the transmission. Its main function is to disconnect and transmit power between the engine and the transmission. The clutch is mounted to the flywheel assembly on the engine crankshaft, enabling gradual engagement between the engine and the vehicle's transmission system, thus ensuring a smooth start. Simultaneously, the clutch can temporarily disconnect the connection between the engine and the transmission during gear shifts, reducing shift shock, and it also acts as a disengagement mechanism during emergency braking, preventing overload of the transmission system and other components, thus providing protection.

[0003] In existing clutch designs, especially in terms of the torsional durability of the driven plate assembly, the torsional durability requirement for the clutch driven plate assembly is typically 5 million cycles. During each torsion process, the damping spring will undergo compression motion within the driven plate window.

[0004] However, conventional designs fail to adequately consider the actual motion trajectory of the damping spring, resulting in a non-unique trajectory during movement, up-and-down swaying, and uneven stress distribution. This accelerates the fatigue and damage of the spring. This design flaw makes the damping spring prone to breakage and wear after endurance testing, seriously affecting the service life and performance stability of the clutch. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an installation structure for protecting springs. By limiting the movement trajectory of the damping spring, it ensures that the stress distribution of the spring is uniform, eliminates lateral offset and vertical sway, significantly extends the life of the spring to more than 5 million cycles, and reduces the risk of breakage.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The mounting structure for protecting the spring includes a housing, an end cap threaded to the outside of the housing, a mounting plate mounted inside the housing, a limiting block mounted on one side of the mounting plate, a shock-absorbing spring mounted inside the housing for cushioning and damping, a guide block mounted on the outside of the mounting plate, and a fixing assembly mounted on one side of the mounting plate.

[0008] In one optional embodiment, a groove is provided on the outer casing, and the guide block is slidably connected to the inner side of the outer casing through the groove.

[0009] In one optional embodiment, two sets of mounting plates and limiting blocks are provided, and the two sets of mounting plates and limiting blocks are symmetrically arranged on both sides of the shock-absorbing spring.

[0010] In one alternative implementation, the inner diameter of the damping spring is tightly fitted with the outer wall of the limiting block.

[0011] In one optional embodiment, the end cap has a through hole, through which the mounting plate penetrates the end cap.

[0012] In one alternative embodiment, the fixing component includes a threaded post fixedly connected to one side of the mounting plate and a threaded groove formed inside the limiting block.

[0013] In one alternative implementation, the limiting block is threadedly connected to the threaded post via a threaded groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This invention ensures that stress is evenly distributed across the entire spring body during deformation under load. This design effectively eliminates lateral shift and vertical swaying that may occur during spring operation, thereby ensuring high stability of the assembly's torque performance. Furthermore, this structure fundamentally avoids the risk of breakage caused by uneven stress or abnormal movement in the damping spring. Actual testing has verified that the spring's service life is significantly extended, stably reaching over 5 million cycles.

[0016] 2. In actual operation, the limiting block can be easily removed from the threaded post with a simple rotation. This design allows users to conveniently disassemble and install the limiting block according to actual usage needs. When faced with springs of different specifications, users can quickly replace the appropriate limiting block to adapt to diverse working scenarios and spring specification requirements.

[0026] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0027] Please refer to Figures 1-5The mounting structure for protecting the spring includes a housing 1 and an end cap 2 threaded to the outside of the housing 1; it also includes a mounting plate 301 mounted inside the housing 1, a limiting block 302 mounted on one side of the mounting plate 301, a shock-absorbing spring 303 mounted inside the housing 1 for buffering and shock absorption, a guide block 304 mounted on the outside of the mounting plate 301, and a fixing assembly mounted on one side of the mounting plate 301.

[0028] In a preferred embodiment of this invention, the shock-absorbing spring 303 is elastic and can deform under external force to absorb and store energy. When impact force or vibration is transmitted to the shock-absorbing spring 303, the shock-absorbing spring 303 is compressed or stretched, thereby converting the impact energy into elastic potential energy.

[0029] In a preferred embodiment of this utility model, a groove 305 is provided on the outer shell 1, and the guide block 304 is slidably connected to the inner side of the outer shell 1 through the groove 305. During the movement of the guide block 304, the two side walls of the groove 305 can accurately guide and effectively limit the guide block 304, ensuring that the guide block 304 can only move in a straight line along the path specified by the groove 305, avoiding deviation or shaking, ensuring the conditions for the use of the damping spring, and preventing the damping spring from moving up and down.

[0030] In a preferred embodiment of this utility model, two sets of mounting plates 301 and limiting blocks 302 are provided, and the two sets of mounting plates 301 and limiting blocks 302 are symmetrically arranged on both sides of the shock-absorbing spring 303, so as to realize the installation and positioning of the shock-absorbing spring 303.

[0031] In a preferred embodiment of this utility model, the inner diameter of the shock-absorbing spring 303 is tightly fitted with the outer wall of the limiting block 302. This tight fit allows the limiting block 302 to provide a stable fixation and precise limiting effect on the shock-absorbing spring 303, preventing the spring from shifting or shaking during operation.

[0032] In a preferred embodiment of this utility model, the end cap 2 is provided with a through hole, and the mounting plate 301 penetrates the end cap 2 through the through hole. Through this ingenious design, the mounting plate 301 is not completely inside the end cap 2, but a part of it can extend to the outer area of ​​the end cap 2.

[0033] In a preferred embodiment of this utility model, the fixing component includes a threaded post 401 fixedly connected to one side of the mounting plate 301 and a threaded groove 402 opened inside the limiting block 302. Through the threaded connection method in which the threaded post 401 and the threaded groove 402 cooperate with each other, it can be ensured that the limiting block 302 can be installed firmly and reliably on the mounting plate 301, providing a strong guarantee for the stable operation of the overall structure.

[0034] In a preferred embodiment of this utility model, the limiting block 302 is threadedly connected to the threaded post 401 through the threaded groove 402. This threaded connection method allows the limiting block 302 to be firmly installed on the mounting plate 301, and the limiting block 302 can be easily disassembled and installed according to actual needs, so as to replace the limiting block 302 to adapt to different specifications of shock-absorbing springs 303.

[0035] During operation, the moving mounting plate 301 drives the guide block 304 to move. During the movement of the guide block 304, the two side walls of the slide groove 305 provide precise guidance and effective positioning, ensuring that the guide block 304 can only move linearly along the path specified by the slide groove 305. This prevents deviation or wobbling, ensuring the optimal operating conditions for the damping spring 303 and preventing vertical movement of the damping spring. This makes the overall torque performance of the assembly more stable, and the structure effectively avoids the risk of breakage of the damping spring. By rotating the limiting block 302, it can be removed from the threaded post 401. The limiting block 302 can be easily disassembled and installed according to actual needs, allowing for replacement to accommodate different specifications of the damping spring 303.

[0036] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

[0037] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
