Description
Technical Field
[0001] This utility model belongs to the technical field of vibration damper hole system correction instruments, and in particular relates to a vibration damper hole system correction tool. Background Technology
[0002] The applicant describes a torsion-limiting flywheel damper assembly in Patent Document 1, which presses the various torsion-limiting components of a traditional torsion-limiting damper between a flexible disc and a flywheel. In this way, the flexible disc acts as a pressure cap of the traditional torsion-limiting damper, and the flywheel acts as a support disc of the traditional torsion-limiting damper. That is to say, this torsion-limiting flywheel damper assembly integrates the traditional torsion-limiting damper and the flywheel into a single structure, eliminating the two parts of the pressure cap and the support disc, reducing the number of parts, and significantly reducing production costs. Moreover, this torsion-limiting flywheel damper assembly can be fixedly mounted on the crankshaft of the engine as a whole, which also saves assembly steps compared to separate assembly.
[0003] However, after the aforementioned integrated shock absorber's torsion limiting components slip and cause misalignment of the hole system, it is difficult to reset the misaligned hole system of the integrated shock absorber using only manpower or existing tools, because each torsion limiting component is press-fitted between the flexible disc and the flywheel, and the flexible disc and the flywheel are tightly connected together.
[0004] Patent Document 1: Chinese Invention Patent with Publication No. CN114838064A, a Torque-Limiting Flywheel Vibration Damper Assembly. Utility Model Content
[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a hole system correction tool for a shock absorber, which solves the problem that it is difficult to reset the hole system of a torque-limiting flywheel shock absorber assembly described in Patent Document 1 after the torque-limiting component slips and causes misalignment.
[0006] To achieve the above and other related objectives, this utility model provides a hole system correction tool for a vibration damper, used to correct the hole system of an integrated vibration damper in which a torsion limiting component is press-fitted between a flexible disc and a flywheel, comprising:
[0007] The drive gear is driven by an external force;
[0008] The driven gear meshes with the driving gear. A plurality of torque limiting component positioning pins are fixedly connected to the driven gear, and one torque limiting component positioning pin corresponds to one torque limiting component positioning hole on the torque limiting component.
[0009] The connecting rod arm is rotatably connected to the driven gear, and each of its multiple ends is fixed with a flywheel positioning pin, with each flywheel positioning pin corresponding to a flywheel positioning hole on the flywheel.
[0010] Optionally, at least one end of the connecting arm is provided with a mounting portion, and the drive gear is fixed in the mounting portion; an external force drives the end of the connecting arm to rotate, thereby driving the rotation of the drive gear.
[0011] Optionally, the mounting portion includes a first mounting plate and a second mounting plate, the first mounting plate being fixedly connected to the end of the connecting rod arm; the second mounting plate and the first mounting plate fixedly clamp the drive gear.
[0012] Optionally, a driven arm is fixed between the first mounting plate and the second mounting plate; a driving arm is fixed to the driven arm and extends outward.
[0013] Optionally, the connecting arm is "V" shaped, and the center of the connecting arm is rotatably connected to the center of the driven gear.
[0014] As described above, the hole system correction tool for a vibration damper according to this utility model has at least the following beneficial effects:
[0015] The hole system correction tool for this vibration damper is rotatably connected to a connecting rod arm and a driven gear. Each end of the connecting rod arm is fixed with a flywheel locating pin, with each flywheel locating pin corresponding to a flywheel locating hole on the flywheel. The driven gear is fixed with multiple torsion limiting component locating pins, each corresponding to a torsion limiting component locating hole on the torsion limiting component. This design allows the operator to adjust the relative position of the connecting rod arm and the driven gear by rotating the connecting rod arm, ensuring that the torsion limiting component locating pins and flywheel locating pins can be inserted into their respective locating holes. The operator then applies external force to the driving gear, causing the driven gear to rotate, which in turn rotates the torsion limiting components, thus correcting the misaligned components. Compared to relying solely on manual labor or existing torsion bars and other tools, this vibration damper hole system correction tool is more targeted and easier to operate.

[0022] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0023] Please see Figures 1 to 3 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0024] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.
[0025] Please see Figure 1 This utility model provides a hole system correction tool 1 for a vibration damper, used to correct the hole system of an integrated vibration damper 2 in which a torsion limiting component 23 is press-fitted between a flexible disc 21 and a flywheel 22. For the specific structure of the integrated vibration damper 2, please refer to patent document CN114838064A. This hole system correction tool 1 includes:
[0026] like Figure 2 and Figure 3 The drive gear 11 shown is driven by an external force. It generally utilizes the lever principle and can be manually driven by the operator. The specific structure here will be described below.
[0027] like Figure 2 and Figure 3The driven gear 12 shown meshes with the driving gear 11. Multiple torque-limiting component positioning pins 14 are fixedly connected to the driven gear 12. Each torque-limiting component positioning pin 14 corresponds to a torque-limiting component positioning hole 231 on the torque-limiting component 23. Figure 1 The integrated damper 2 shown has four torque limiting component positioning holes 231 on its torque limiting component 23, and correspondingly, four torque limiting component positioning pins 14 are fixedly connected to the driven gear 12.
[0028] like Figure 2 and Figure 3 The connecting arm 13 shown is rotatably connected to the driven gear 12, and each of its multiple ends is fixed with a flywheel positioning pin 15, with each flywheel positioning pin 15 corresponding to a flywheel positioning hole 221 on the flywheel 22 of the integrated damper 2.
[0029] Through the aforementioned structural design, the hole system correction tool 1 for this vibration damper addresses the issue of misalignment of the hole system caused by slippage of the torque limiting component 23 in the integrated vibration damper 2. Because the connecting rod arm 13 and the driven gear 12 are rotatably connected, the operator can adjust their relative positions by rotating the connecting rod arm 13. This allows the torque limiting component positioning pin 14 on the driven gear 12 to insert into the torque limiting component positioning hole 231, and the flywheel positioning pin 15 to insert into the flywheel positioning hole 221. The operator then applies external force to the driving gear 11, causing the driven gear 12 to rotate, which in turn causes the torque limiting component 23 to rotate, thus adjusting the misaligned torque limiting component 23. Compared to relying solely on manual labor or existing tools such as torsion bars, the hole system correction tool 1 for this vibration damper is more targeted and easier to operate, solving the problem of difficulty in resetting the integrated vibration damper 2, i.e., the torque limiting flywheel 22 vibration damper assembly described in Patent Document 1, after slippage of its torque limiting component 23 causing misalignment of the hole system.
[0030] It should be noted that, because the flywheel locating pin 15 on the end of the connecting rod arm 13 corresponds to the flywheel locating hole 221 on the shock absorber flywheel 22, and is combined as follows: Figure 1 As shown in the structure of the integrated shock absorber 2, the two ends of the connecting rod arm 13 naturally extend outward from the outermost ring of the driven gear 12.
[0031] In another implementation, please refer to Figure 2 and Figure 3The connecting arm 13 has a mounting portion 16 at at least one end, and the drive gear 11 is fixedly connected in the mounting portion 16. An external force drives the end of the connecting arm 13 to rotate, thereby driving the drive gear 11 to rotate. Compared with the method of arranging the connecting arm 13 and the drive gear 11 separately, the structure of the entire hole system correction tool 1 is more compact and easier to operate. In order to improve the reliability of the hole system correction tool 1, a mounting portion 16 can be fixedly installed at each end of the connecting arm 13. The specific structure of the mounting portion 16 will be described below.
[0032] In another implementation, please refer to Figure 2 and Figure 3 The mounting portion 16 includes a first mounting plate 161 and a second mounting plate 162. The first mounting plate 161 is fixedly connected to the end of the connecting rod arm 13. The second mounting plate 162 and the first mounting plate 161 fixably clamp the drive gear 11. The hole system correction tool 1 also includes a driven arm 17 and a drive arm 18. The driven arm 17 is fixedly connected between the first mounting plate 161 and the second mounting plate 162. The drive arm 18 and the driven arm 17 are fixedly connected and extend outward.
[0033] like Figure 3 As shown, we will now describe the structure of the mounting part 16 in more detail. The first mounting plate 161 and the second mounting plate 162 are two trapezoidal plates arranged opposite each other. There is space between the first mounting plate 161 and the second mounting plate 162 for placing the drive gear 11.
[0034] like Figure 3 As shown, the first mounting plate 161 and the second mounting plate 162 are fixedly connected by bolts and fixing pins, and the driven gear 12 is also fixedly connected between the first mounting plate 161 and the second mounting plate 162 by bolts and fixing pins.
[0035] The structure of the mounting part 16 described above facilitates the disassembly of the hole system correction tool 2 and the replacement of the driving gear 11 and the driven gear 12.
[0036] In another implementation, please refer to Figure 3 The connecting arm 13 is "V" shaped, and the center of the connecting arm 13 is rotatably connected to the center of the driven gear 12. Each of the two ends of the connecting arm 13 is equipped with a mounting part 16. The connecting arm 13 structure in this embodiment is more stable than the "I" shaped structure and fits better with the position of the flywheel positioning hole 221 of the integrated shock absorber 2 as shown in the figure.
[0037] In other implementations, such as Figure 2 and Figure 3As shown, the specific dimensions and number of gear rings of the driving gear 11 and the driven gear 12 are designed by the designer based on the torque required to turn the torque limiting component 23 of the integrated vibration damper 2 when correcting the hole system of the integrated vibration damper 2, and will not be elaborated here. In order to further improve the operability of this hole system correction tool 1, the designer can also open a weight reduction groove 121 on the driven gear 12 and set anti-slip texture 181 on the driving arm 18, etc.
[0038] It should be noted that the naming of the flywheel positioning hole 221 and the torsion limiting component positioning hole 231 on the integrated vibration damper 2 in this manual is relative to the hole system correction tool 1. Both holes belong to the hole system of the integrated vibration damper 2. The hole system consists of two or more holes with a certain relative position in space. Common hole systems include coaxial hole systems, parallel hole systems, and perpendicular hole systems. The hole system of the integrated vibration damper 2 corrected by this hole system correction tool belongs to the coaxial hole system. The hole system of the integrated vibration damper 2 will not be described in detail here.
[0039] In summary, this utility model utilizes a rotatable connection between a connecting arm 13 and a driven gear 12. Each end of the connecting arm 13 is fixedly connected to a flywheel positioning pin 15, with each flywheel positioning pin 15 corresponding to a flywheel positioning hole 221 on the flywheel 22. The driven gear 12 is fixedly connected to multiple torque-limiting component positioning pins 14, with each torque-limiting component positioning pin 14 corresponding to a torque-limiting component positioning hole 231 on the torque-limiting component 23. This design allows the operator to quickly locate the misalignment of the hole system in the integrated vibration damper 2 after the torque-limiting component 23 slips. Rotating the connecting rod arm 13 adjusts its relative position to the driven gear 12, allowing the torque limiting component positioning pin 14 to insert into the torque limiting component positioning hole 231 and the flywheel positioning pin 15 to insert into the flywheel positioning hole 221. The operator then applies external force to the driving gear 11, causing the driven gear 12 to rotate, which in turn causes the torque limiting component 23 to rotate, thereby adjusting the misaligned torque limiting component 23. Compared to relying solely on manual labor or existing tools such as torsion bars, the hole system correction tool 1 of this shock absorber is more targeted and easier to operate. Therefore, this utility model effectively overcomes the shortcomings of the prior art and has high industrial application value.
[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
