A motorcycle clutch misalignment prevention device and assembly method

Abstract

The application provides a motorcycle clutch mismatch prevention device and an assembling method, and belongs to the technical field of motorcycle clutch production auxiliary equipment structures. The mismatch prevention device is designed with a mismatch prevention pad and an inductor in the first tooth groove. When the ring teeth of the first friction plate and the ring teeth of the second friction plate are not correctly installed in the corresponding tooth grooves, the first friction plate, the driven plate and the second friction plate of the clutch installed in the assembling box cannot be completely attached, so that the friction plate will slip when the clutch bolt is tightened. The operator re-installs the clutch according to this, adjusts the positions of the ring teeth of the first friction plate and the ring teeth of the second friction plate, thereby solving the problem that in the installation and production process of the clutch in the prior art, the operator is prone to misalign the installation angle of the second friction plate to the position of the shallow groove of the outer cover, or misalign the installation angle of the first friction plate to the position of the deep groove of the outer cover.

Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment structure for motorcycle clutch production, and specifically relates to a misfitting device and assembly method for a motorcycle clutch. Background Technology

[0002] The main function of a motorcycle clutch is to ensure smooth starting and driving, meet gear shifting requirements, cut off power, and facilitate braking. It mainly consists of friction plates, a pressure plate, a driven plate, an outer cover, and a lifting plate. The multiple friction plates, in their engaged, disengaged, and partially engaged states, respectively transmit or cut off power. The toothed design of the friction plates is primarily to disperse the impact force during clutch operation, thereby extending the clutch's service life. The deep and shallow grooves in the clutch cover mainly improve sealing performance and lubrication, while reducing wear and noise.

[0003] In order to adapt to the design of deep and shallow grooves on the outer cover during the assembly process of the clutch, the installation angle of the first friction plate closest to the lifting plate must be staggered from that of the other friction plates, so that the ring teeth of the first friction plate can be inserted into the shallow groove of the outer cover, while the ring teeth of the other friction plates are inserted into the deep groove of the outer cover.

[0004] During the clutch installation process, operators may mistakenly install non-first friction plates at the shallow groove of the outer cover, or install the first friction plate at the deep groove of the outer cover. This can prevent subsequent parts from being installed smoothly, affecting production efficiency and product quality. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a misfitting device and assembly method for a motorcycle clutch, which solves the problem that in the prior art, during the clutch installation and production process, operators are prone to misaligning the installation angle of non-first friction plates to the shallow groove of the outer cover, or misaligning the installation angle of the first friction plate to the deep groove of the outer cover.

[0006] To achieve the above and other related objectives, the present invention provides an anti-misfit device for a motorcycle clutch, used to assist in the installation of a motorcycle clutch. The device includes an assembly box, a positioning rod, a positioning sleeve, and a retaining ring. The clutch is installed in the assembly box with the clutch lifting plate facing upwards. The friction plate closest to the lifting plate in the clutch is the first friction plate, and the other friction plates are the second friction plates. The inner wall of the assembly box has a first toothed groove and a second toothed groove spaced apart from each other. An anti-misfit pad and a sensor are disposed in the first toothed groove. When the clutch pressure plate is in contact with the inner bottom of the assembly box, the top of the anti-misfit pad is lower than the first friction plate and higher than the second friction plate. The positioning rod is a telescopic rod disposed inside the assembly box, and the sensor controls the extension and retraction of the positioning rod. The positioning sleeve is coaxially fitted onto the positioning rod, and the positioning sleeve and the center hole on the clutch lifting plate are coaxially engaged. A pull plate is disposed on the positioning rod, the positioning sleeve is located below the pull plate, and the retaining ring is used to insert between the positioning sleeve and the pull plate.

[0007] Optionally, the positioning rod is extended and retracted by a cylinder.

[0008] Optionally, the positioning sleeve and the center hole on the lifting plate are interference-fitted.

[0009] The method for assembling a clutch using the anti-misfit device for a motorcycle clutch described above includes the following steps:

[0010] S1: Assemble the clutch pressure plate, friction plate, driven plate and center sleeve into a center sleeve assembly;

[0011] S2: With the pressure plate facing down, the center sleeve assembly is installed into the assembly box, and the positioning rod passes through the center of the center sleeve assembly;

[0012] S3: Fit the clutch spring onto the pin of the pressure plate;

[0013] S4: The lifting plate is installed onto the center sleeve assembly, and the center hole of the positioning sleeve and the lifting plate are coaxially engaged;

[0014] S5: Insert the bolt through the side hole of the lifting plate into the spring;

[0015] S6: When the anti-misalignment pad and the second friction plate have no interference, and the sensor detects the presence of the friction plate's teeth in the first tooth groove, the retaining ring can be inserted between the positioning sleeve and the pull plate to tighten the bolt, ensuring that the first friction plate, the driven plate, and the second friction plate are tightly fitted without slipping.

[0016] Optionally, when the anti-error pad and the second friction plate's teeth interfere with each other, and / or when the sensor detects that there are no friction plate teeth in the first tooth groove, the method further includes the step of:

[0017] S7: Reassemble the clutch.

[0018] As described above, the anti-mismatch device for a motorcycle clutch of the present invention has at least the following beneficial effects:

[0019] 1. This anti-misfit device, through the design of an anti-misfit pad and sensor in the first tooth groove, prevents the first friction plate, driven plate, and second friction plate of the clutch from fully engaging when the ring teeth of the first and second friction plates are not correctly installed in their corresponding grooves. This causes slippage when tightening the clutch bolts, allowing the operator to reinstall the clutch and adjust the positions of the ring teeth of the first and second friction plates. This solves the problem in existing clutch installation processes where operators easily misalign the second friction plate into the shallow groove of the outer cover or the first friction plate into the deep groove, leading to subsequent parts not being properly installed, affecting production efficiency and product quality. Furthermore, this anti-misfit device, through the coaxial fitting of the positioning sleeve onto the positioning rod and the coaxial fit between the positioning sleeve and the center hole of the clutch lifting plate, ensures the coaxiality between the clutch center sleeve assembly and the lifting plate, improving product assembly quality.

[0020] 2. This assembly method utilizes the anti-misfit pad and sensor design in the first tooth groove of the motorcycle clutch's anti-misfit device. This allows the operator to determine whether the first friction plate and the second friction plate are properly installed by observing whether slippage occurs between them when tightening the bolts. If the installation position is incorrect, causing slippage between the first, driven, and second friction plates during bolt tightening, the operator can reinstall all clutch components. This prevents the second friction plate from being installed at a misaligned angle in the shallow groove of the outer cover, or the first friction plate at a misaligned angle in the deep groove of the outer cover, which could prevent subsequent components from being installed smoothly, thus affecting production efficiency and product quality.

Detailed Implementation

[0027] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0028] Please see Figures 1 to 4 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 to facilitate understanding. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0029] 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.

[0030] Please see Figure 1This invention provides a misfit prevention device for a motorcycle clutch, used to assist in the installation of a motorcycle clutch. First, we introduce the structure of the clutch. This clutch is part of a continuously variable transmission (CVT) commonly used in motorcycles. The clutch includes a pressure plate 14, on which a pin is provided. The pin has a pin hole. Friction plates and driven plates 16 are mounted on the pressure plate 14 in sequence. A spring 13 passes through the friction plates and driven plates 16 and is fitted onto the pin. All these parts, together with the center sleeve, form the center sleeve assembly of the clutch. Those skilled in the art can understand the detailed structure of this clutch by consulting the literature.

[0031] like Figure 1 As shown, we have given different names to the different friction plates. The friction plate that is closest to the lifting plate 11 in the clutch is the first friction plate 15, and the other friction plates are the second friction plates 17, for the convenience of the following description.

[0032] like Figure 1 As shown, we will now describe in detail the structure of the anti-misfit device. The device includes an assembly box 21, a positioning rod 22, a positioning sleeve 23, and a retaining ring 24. The clutch is installed in the assembly box 21 with the lifting plate 11 facing upwards. The inner wall of the assembly box 21 has a first toothed groove and a second toothed groove that are spaced apart from each other. An anti-misfit pad 25 and a sensor 26 are provided in the first toothed groove. When the pressure plate 14 of the clutch is in contact with the inner bottom of the assembly box 21, the top of the anti-misfit pad 25 is lower than the first friction plate 15 and higher than the second friction plate 17. The positioning rod 22 is a telescopic rod installed inside the assembly box 21, and the sensor 26 controls the extension and retraction of the positioning rod 22.

[0033] like Figure 1 As shown, the positioning sleeve 23 is coaxially fitted onto the positioning rod 22, and the positioning sleeve 23 and the center hole on the clutch lifting plate 11 are coaxially engaged; the positioning rod 22 is provided with a pull plate 27, the positioning sleeve 23 is located below the pull plate 27, and the retaining ring 24 is used to insert between the positioning sleeve 23 and the pull plate 27.

[0034] like Figure 1As shown, based on the structure of the anti-misfit device described above, the design of the anti-misfit pad 25 and sensor 26 in the first tooth groove ensures that when the ring teeth of the first friction plate 15 do not engage in the first tooth groove and / or the ring teeth of the second friction plate 17 do not engage in the second tooth groove, the first friction plate 15, driven plate 16 and second friction plate 17 of the clutch installed in the assembly box 21 cannot be fully fitted together. As a result, when tightening the clutch bolts 12, slippage will occur between the first friction plate 15, driven plate 16 and second friction plate 17. The operator can then know that the clutch is not installed correctly and can reinstall the clutch by adjusting the positions of the ring teeth of the first friction plate 15 and the second friction plate 17. This solves the problem in the prior art where, during the clutch installation process, operators easily misalign the installation angle of the second friction plate 17 to the shallow groove of the outer cover or the installation angle of the first friction plate 15 to the deep groove of the outer cover, resulting in subsequent parts not being able to be installed smoothly, affecting production efficiency and product quality.

[0035] like Figure 1 As shown, this anti-misfit device also ensures the coaxiality between the clutch center sleeve assembly and the lifting plate 11 by coaxially fitting the positioning sleeve 23 onto the positioning rod 22 and coaxially engaging the center hole on the positioning sleeve 23 and the clutch lifting plate 11, thereby improving the assembly quality of the product.

[0036] like Figure 1 As shown, the pull plate 27 is located at the top of the positioning rod 22, which avoids wasting the length of the positioning rod 22 compared to other positions on the positioning rod 22.

[0037] In another implementation, please refer to Figure 1 The positioning rod 22 is driven by the cylinder 3 to extend and retract. More specifically, the cylinder 3 is equipped with a slider 33, and the bottom of the positioning rod 22 is fixedly connected to the slider 33. The outer wall of the slider 33 is sealed to the inner wall of the cylinder 3. The cylinder 3 has an air inlet at the top and a bottom. The slider 33 slides along the inner wall of the cylinder 3 between the two air inlets. The upper and lower air inlets are each connected to a solenoid valve 32 through an air pipe. When the lifting plate 11 is installed on the center sleeve assembly, the power supply 31 is turned on, and the ventilation device supplies air to the solenoid valve 32. When the sensor 26 detects the toothed ring of the first friction plate 15 in the first toothed groove, the solenoid valve 32 closes the lower channel. The ventilation device sends gas from the upper part of the solenoid valve 32 to the upper part of the cylinder 3. Under the action of the gas, the slider 33 begins to move downward, thereby driving the positioning rod 22 to retract.

[0038] like Figure 1As shown, if the sensor 26 does not detect the toothed ring of the first friction plate 15 in the first toothed groove, the solenoid valve 32 closes the lower channel, and the ventilation device sends gas from the lower part of the solenoid valve 32 into the lower part of the cylinder 3. Under the action of the gas, the slider 33 begins to move upward, thereby driving the positioning rod 22 to extend outward.

[0039] In another implementation, please refer to Figure 1 The sensor 26 can be selected as a distance sensor 26 and is set at the position corresponding to the first tooth groove and the tooth ring of the first friction plate 15.

[0040] In another implementation, please refer to Figure 1 The friction plate can be a commonly used eight-tooth structure, with eight first and eight second tooth grooves, arranged at equal intervals in the circumferential direction. Two adjacent ring teeth of the same friction plate are spaced 45° apart in the circumferential direction, and the first and second adjacent tooth grooves on the inner wall of the assembly box 21 are spaced 22.5° apart in the circumferential direction.

[0041] In other implementations, such as Figure 1 As shown, the positioning sleeve 23 and the center hole on the lifting plate 11 are interference-fitted. More specifically, the bottom of the positioning sleeve 23 can be designed with a rubber sleeve that fits with the center hole on the lifting plate 11, thereby ensuring that the lifting plate 11 and the positioning sleeve 23 are coaxial. The positioning sleeve 23 and the positioning rod 22 are coaxial, and the center sleeve assembly is coaxially fitted onto the positioning rod 22, thus ensuring the coaxiality of the lifting plate 11 and the center sleeve assembly, thereby ensuring the assembly quality of the clutch.

[0042] Of course, there are other ways to make the positioning sleeve 23 and the center hole on the lifting plate 11 coaxially cooperate, such as setting a clevis at the bottom of the center sleeve, which will not be elaborated here.

[0043] Please see Figures 1 to 4 Based on the assembly method of the anti-misfit device for a motorcycle clutch described above, we will give the steps for clutch installation regarding whether the first friction plate 15 and the second friction plate 17 are installed in place, specifically divided into three cases.

[0044] The first case, such as Figure 1 and Figure 2 As shown, if the teeth of the first friction plate 15 and the second friction plate 17 can be installed in the correct positions, that is, if the first friction plate 15 can be engaged into the shallow groove of the outer cover during subsequent assembly, and the second friction plate 17 can be engaged into the deep groove of the outer cover during subsequent reassembly, the assembly method includes the following steps:

[0045] S1: As with existing technology, we first assemble the clutch pressure plate 14, friction plate, driven plate 16 and center sleeve into a center sleeve assembly;

[0046] S2: Then, with the pressure plate 14 facing down, the assembled center sleeve assembly is installed into the assembly box 21, and the positioning rod 22 passes through the center of the center sleeve assembly; the first friction plate 15 is engaged in the first tooth groove, and the second friction plate 17 is engaged in the second tooth groove. The ring teeth of the first friction plate 15 and the ring teeth of the second friction plate 17 can be installed in the correct position, that is, the anti-misalignment pad 25 and the second friction plate 17 do not interfere with each other;

[0047] S3: Fit the clutch spring 13 onto the pin of the pressure plate 14;

[0048] S4: Install the lifting plate 11 onto the center sleeve assembly, and the positioning sleeve 23 and the center hole of the lifting plate 11 are coaxially engaged.

[0049] S5: Insert the bolt 12 through the side hole of the lifting plate 11 into the spring 13;

[0050] S6: The retaining ring 24 is inserted between the positioning sleeve 23 and the pull plate 27. The sensor 26 detects the presence of the friction plate teeth in the first tooth groove. The sensor 26 controls the positioning rod 22 to retract. The lifting plate 11 presses down on the spring 13 until the lifting plate 11 and the bolt are in contact. The center sleeve assembly is fixed and the bolt 12 is tightened. There will be no slippage between the first friction plate 15, the driven plate 16 and the second friction plate 17. The retaining ring 24 acts like a washer to ensure that the first friction plate 15, the driven plate 16 and the second friction plate 17 are in close contact. Without the retaining ring 24 inserted between the positioning sleeve 23 and the pull plate 27, the first friction plate 15, the driven plate 16 and the second friction plate 17 cannot be in close contact.

[0051] The second scenario, such as Figure 1 and Figure 3 As shown, if both the first friction plate 15 and the second friction plate 17 are installed in the second tooth groove, that is, if the first friction plate 15 is not misaligned with the position of the second friction plate 17, the outer ring teeth of the first friction plate 15 cannot engage with the shallow groove of the clutch cover. The assembly method includes the following steps:

[0052] S1: The preceding work is the same: assemble the clutch pressure plate 14, friction plate, driven plate 16 and center sleeve into a center sleeve assembly.

[0053] S2: With the pressure plate 14 facing downwards, the center sleeve assembly is installed into the assembly box 21, and the positioning rod 22 passes through the center of the center sleeve assembly; the first friction plate 15 is engaged in the second tooth groove, the second friction plate 17 is engaged in the second tooth groove, the anti-misalignment pad 25 and the second friction plate 17 do not interfere with each other, but at this time there are no friction plate teeth in the first tooth groove;

[0054] S3: Next, the clutch spring 13 is fitted onto the pin of the pressure plate 14;

[0055] S4: Install the lifting plate 11 onto the center sleeve assembly, and the positioning sleeve 23 and the center hole of the lifting plate 11 are coaxially engaged.

[0056] S5: Insert the bolt 12 through the side hole of the lifting plate 11 into the spring 13;

[0057] S6: The retaining ring 24 is inserted between the positioning sleeve 23 and the pull plate 27. The sensor 26 detects that there is no friction plate in the first tooth groove. The sensor 26 controls the positioning rod 22 to extend outward. The center sleeve assembly cannot be fixed. The bolt 12 is tightened. The first friction plate 15, the driven plate 16 and the second friction plate 17 are not in close contact, and slippage occurs naturally. In this case, the operator knows that the clutch is not installed properly and takes the clutch out of the assembly box 21.

[0058] S7: Reassemble the clutch.

[0059] The third scenario, such as Figure 1 and Figure 4 As shown, regardless of whether the first friction plate 15 is installed in the first toothed groove or the second toothed groove, as long as the second friction plate 17 is installed in the first toothed groove, the toothed ring of the second friction plate 17 will not be able to engage with the deep groove of the outer cover during subsequent assembly. The assembly steps are as follows:

[0060] S1: The clutch pressure plate 14, friction plate, driven plate 16 and center sleeve are still assembled into a center sleeve assembly;

[0061] S2: With the pressure plate 14 facing downwards, the center sleeve assembly is inserted into the assembly box 21, and the positioning rod 22 passes through the center of the center sleeve assembly; the second friction plate 17 is engaged in the first tooth groove, and the anti-misalignment pad 25 and the ring teeth of the second friction plate 17 interfere with each other. At this time, the pressure plate 14 cannot fall into the bottom of the assembly box 21, and the bottom of the pressure plate 14 and the inner interior of the assembly box 21 cannot be tightly attached, but the operator may not notice it.

[0062] S3: Fit the clutch spring 13 onto the pin of the pressure plate 14;

[0063] S4: Install the lifting plate 11 onto the center sleeve assembly, and the positioning sleeve 23 and the center hole of the lifting plate 11 are coaxially engaged.

[0064] S5: Insert the bolt 12 through the side hole of the lifting plate 11 into the spring 13;

[0065] S6: Even if the operator does not notice that the friction plate is installed incorrectly, because the bottom of the pressure plate 14 and the interior of the assembly box 21 cannot fit together, the gap between the positioning sleeve 23 and the pull plate 27 is small, and the retaining ring 24 cannot be inserted between the positioning sleeve 23 and the pull plate 27. Even if the sensor 26 controls the positioning rod 22 to retract, the first friction plate 15, the driven plate 16 and the second friction plate 17 still cannot fit together. At this time, the operator tightens the bolt 12, and the first friction plate 15, the driven plate 16 and the second friction plate 17 will naturally slip. In this case, the operator knows that the clutch is not installed properly and removes the clutch from the assembly box 21.

[0066] S7: Reassemble the clutch.

[0067] This assembly method, through the description of the three scenarios above, enables the operator to determine whether the ring teeth of the first friction plate 15 and the second friction plate 17 are properly installed by observing whether slippage occurs between the first friction plate 15, the driven plate 16, and the second friction plate 17 when tightening bolt 12. If the installation position is incorrect, and slippage occurs between the first friction plate 15, the driven plate 16, and the second friction plate 17 when tightening bolt 12, the operator can reinstall the clutch components. This avoids the second friction plate 17 being installed at a shallow groove in the outer cover, or the first friction plate 15 being installed at a deep groove in the outer cover, which would prevent subsequent components from being installed smoothly, thus affecting production efficiency and product quality.

[0068] In summary, the anti-misfit device of the present invention, through the design of anti-misfit pad 25 and sensor 26 in the first tooth groove, ensures that when the ring teeth of the first friction plate 15 and the ring teeth of the second friction plate 17 are not correctly installed in the corresponding tooth grooves, the first friction plate 15, driven plate 16 and second friction plate 17 of the clutch installed in the assembly box 21 cannot be completely pressed together. As a result, when tightening the clutch bolt 12, slippage will occur between the first friction plate 15, driven plate 16 and second friction plate 17. The operator can then reinstall the clutch and adjust the position of the ring teeth of the first friction plate 15 and the second friction plate 17. This solves the problem in the prior art where, during the clutch installation and production process, operators easily misalign the installation angle of the second friction plate 17 to the shallow groove of the outer cover or the installation angle of the first friction plate 15 to the deep groove of the outer cover, resulting in subsequent parts not being able to be installed smoothly, affecting production efficiency and product quality. Meanwhile, this anti-misfit device also ensures the coaxiality between the clutch center sleeve assembly and the lifting plate 11 by coaxially fitting the positioning sleeve 23 onto the positioning rod 22 and coaxially engaging the center hole on the positioning sleeve 23 and the clutch lifting plate 11, thus improving the assembly quality of the product. The assembly method of this invention allows the operator to determine whether the ring teeth of the first friction plate 15 and the ring teeth of the second friction plate 17 are properly installed by observing whether slippage occurs between the first friction plate 15, the driven plate 16, and the second friction plate 17 when tightening the bolt 12. If the installation position is incorrect, and slippage occurs between the first friction plate 15, the driven plate 16, and the second friction plate 17 when tightening the bolt 12, the operator can reinstall the clutch components. This avoids the second friction plate 17 being misaligned into the shallow groove of the outer cover, or the first friction plate 15 being misaligned into the deep groove of the outer cover, which would prevent subsequent components from being installed smoothly, affecting production efficiency and product quality. Therefore, this invention effectively overcomes the shortcomings of the prior art and has high industrial application value.

[0069] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
