Abstract

The invention provides an anti-mismatching device for a motorcycle clutch and an assembling method, and belongs to the technical field of motorcycle clutch production auxiliary equipment structures. According to the mismatch prevention device, through the design that the mismatch prevention cushion block and the inductor are arranged 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 assembly box cannot be completely attached; therefore, when a bolt of the clutch is fastened, the friction plates slip, and an operator reinstalls the clutch and adjusts the positions of the ring teeth of the first friction plate and the ring teeth of the second friction plate, so that the problem that in the prior art, in the installation and production process of the clutch, the friction plates cannot slip is solved. The problem that the installation angle of the second friction plate is staggered to the position of the shallow groove of the outer cover or the installation angle of the first friction plate is staggered to the position of the deep groove of the outer cover by an operator is easily caused.

Description

Technical Field

[0001] The invention belongs to the technical field of motorcycle clutch production auxiliary equipment structure, and in particular relates to a motorcycle clutch anti-mismatch device and an assembly method. Background Art

[0002] The main function of a motorcycle clutch is to ensure that the motorcycle starts and runs smoothly, meet the requirements of gear shifting, cut off the power, and facilitate braking; it is mainly composed of friction plates, pressure plates, driven plates, outer covers, lifting plates and other components. The combination, separation and semi-combination of multiple friction plates play the role of transmitting or cutting off power respectively. The design of the friction plate with ring teeth is mainly to disperse the impact force during the operation of the clutch, thereby extending the service life of the clutch. The design of the deep and shallow grooves of the clutch cover is mainly to improve the sealing performance and lubrication effect, 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 of the clutch, the installation angle of the first friction plate close to the lifting plate should be staggered with other friction plates, so that the ring teeth of the first friction plate can be installed in the shallow groove of the outer cover, and the ring teeth of other friction plates can be installed in the deep groove of the outer cover.

[0004] During the installation and production process of the clutch, the operator is prone to misalign the installation angle of a non-first friction plate to the position of a shallow groove in the outer cover, or misalign the installation angle of the first friction plate to the position of a deep groove in the outer cover, resulting in the subsequent parts not being installed smoothly, affecting production efficiency and product quality. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide an anti-mismatching device and assembly method for a motorcycle clutch, which is used to solve the problem that in the prior art, during the installation and production process of the clutch, the operator is prone to mismatch the installation angle of a non-first friction plate to the position of a shallow groove of the outer cover, or mismatch the installation angle of the first friction plate to the position of a deep groove of the outer cover.

[0006] To achieve the above-mentioned purpose and other related purposes, the present invention provides an anti-mismatch device for a motorcycle clutch, which is used to assist in installing the clutch of a motorcycle, and comprises an assembly box, a positioning rod, a positioning sleeve and a retaining ring. The clutch is installed in the assembly box, and the lifting plate of the clutch faces upward; the friction plate in the clutch that is closest to the lifting plate is the first friction plate, and the other friction plates are the second friction plates; the inner wall of the assembly box is provided with a first tooth groove and a second tooth groove that are spaced apart from each other, and an anti-mismatch pad and a sensor are arranged in the first tooth groove; when the pressure plate of the clutch is fitted with the inner bottom of the assembly box, the top of the anti-mismatch pad is lower than the first friction plate and higher than the second friction plate; the positioning rod is a telescopic rod arranged inside the assembly box, and the sensor controls the telescopic movement of the positioning rod; the positioning sleeve is coaxially mounted on the positioning rod, and the positioning sleeve and the center hole on the clutch lifting plate are coaxially matched; a pull plate is arranged on the positioning rod, and the positioning sleeve is located below the pull plate, and the retaining ring is used to be inserted between the positioning sleeve and the pull plate.

[0007] Optionally, the positioning rod is driven by a cylinder to achieve extension and retraction.

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

[0009] The method for assembling a clutch using the above-mentioned anti-mismatching device for a motorcycle clutch comprises 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 downward, 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: Fitting the spring of the clutch onto the bolt of the pressure plate;

[0013] S4: Installing the lifting plate onto the center sleeve assembly, wherein the positioning sleeve and the center hole of the lifting plate are coaxially matched;

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

[0015] S6: When there is no interference between the anti-error pad and the ring teeth of the second friction plate, and the sensor detects the presence of the ring teeth of the friction plate in the first tooth groove, the retaining ring can be inserted between the positioning sleeve and the pulling plate to tighten the bolts, so that the first friction plate, the driven plate and the second friction plate are tightly attached without slipping.

[0016] Optionally, when there is interference between the error-proofing pad and the ring teeth of the second friction plate, and or when the sensor detects that there is no ring teeth of the friction plate in the first tooth groove, the method further includes the following steps:

[0017] S7: Reassemble the clutch.

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

[0019] 1. The anti-mismatching device is designed with an anti-mismatching pad and a sensor in the first tooth groove, so that 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 groove, the first friction plate, the driven plate and the second friction plate of the clutch installed in the assembly box cannot be completely close together, so when the bolts of the clutch are tightened, the first friction plate, the driven plate and the second friction plate will slip. The operator reinstalls the clutch accordingly and adjusts the position 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 prior art, during the installation and production process of the clutch, 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, resulting in the inability to smoothly install subsequent parts and components, affecting production efficiency and product quality. At the same time, the anti-mismatching device also ensures the coaxiality between the clutch center sleeve assembly and the lifting plate by coaxially fitting the positioning sleeve on the positioning rod and coaxially matching the positioning sleeve with the center hole on the clutch lifting plate, thereby improving the assembly quality of the product.

[0020] 2. This assembly method uses the design of the anti-mismatch pad and sensor in the first tooth groove of the anti-mismatch device of the motorcycle clutch, so that the operator can determine whether the ring teeth of the first friction plate and the second friction plate of the clutch are properly installed during the installation process according to whether there is slippage between the first friction plate, the driven plate and the second friction plate when tightening the bolts. If the installation position is wrong and slippage occurs between the first friction plate, the driven plate and the second friction plate when tightening the bolts, the operator reinstalls the various components of the clutch, thereby avoiding the installation angle of the second friction plate being staggered to the position of the shallow groove of the outer cover, or the installation angle of the first friction plate being staggered to the position of the deep groove of the outer cover, resulting in the subsequent components not being able to be installed smoothly, affecting production efficiency and product quality.

[0027] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0028] See also Figures 1 to 4 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0029] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0030] See also Figure 1The present invention provides an anti-mismatch device for a motorcycle clutch, which is used to assist in installing the clutch of a motorcycle. First, let us introduce the structure of the clutch. The clutch is a part of a continuously variable transmission commonly used in motorcycles. The clutch includes a pressure plate 14, a bolt post is arranged on the pressure plate 14, a bolt hole is opened on the bolt post, and friction plates and driven plates 16 stacked in sequence are installed on the pressure plate 14. The spring 13 passes through the friction plates and the driven plates 16 and is sleeved on the bolt post. The above parts cooperate with the center sleeve to form a center sleeve assembly of the clutch. Technical personnel in this field can master the detailed structure of the clutch by consulting the information.

[0031] like Figure 1 As shown, we have given different friction plates different names. The friction plate 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, to facilitate subsequent description.

[0032] like Figure 1 As shown, we will next introduce the structure of the anti-mismatching device in detail, which 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 upward; the inner wall of the assembly box 21 is provided with a first tooth groove and a second tooth groove spaced apart from each other, and an anti-mismatching pad 25 and a sensor 26 are provided in the first tooth groove; when the pressure plate 14 of the clutch and the inner bottom of the assembly box 21 are fitted together, the top of the anti-mismatching 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 arranged inside the assembly box 21, and the sensor 26 controls the telescopic movement of the positioning rod 22.

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

[0034] like Figure 1As shown, according to the structure of the anti-mismatching device described above, we have designed that the anti-mismatching pad 25 and the sensor 26 are arranged in the first tooth groove, so that when the ring teeth of the first friction plate 15 are not engaged in the first tooth groove and / or the ring teeth of the second friction plate 17 are not engaged in the second tooth groove, the first friction plate 15, the driven plate 16 and the second friction plate 17 of the clutch loaded into the assembly box 21 cannot be completely close to each other, so that when the bolts 12 of the clutch are tightened, the first friction plate 15, the driven plate 16 and the second friction plate 17 will slip, and the operator can know that the clutch is not installed properly, and then reinstall the clutch and adjust the positions of the ring teeth of the first friction plate 15 and the ring teeth of the second friction plate 17, thereby solving the problem that in the prior art, during the installation and production process of the clutch, the operator is prone to misalign the installation angle of the second friction plate 17 to the position of the shallow groove of the outer cover, or misalign the installation angle of the first friction plate 15 to the position of the deep groove of the outer cover, resulting in the subsequent parts cannot be installed smoothly, affecting the production efficiency and product quality.

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

[0036] like Figure 1 As shown, the pull plate 27 is arranged at the top end of the positioning rod 22 , which can avoid wasting the length of the positioning rod 22 compared to being arranged at other positions of the positioning rod 22 .

[0037] In another embodiment, see Figure 1 The positioning rod 22 is driven by the cylinder 3 to extend and retract. A more specific design is that a slider 33 is provided in the cylinder 3, and the bottom of the positioning rod 22 is fixedly connected to the slider 33. The outer wall of the slider 33 is sealed with the inner wall of the cylinder 3. The upper and lower parts of the cylinder 3 are each provided with an air inlet. 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 gathered into 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 equipment supplies air to the solenoid valve 32. When the sensor 26 detects that there is a gear ring with the first friction plate 15 in the first tooth groove, the solenoid valve 32 closes the lower channel, and the ventilation equipment 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 starts to move downward, thereby driving the positioning rod 22 to retract.

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

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

[0040] In another embodiment, see Figure 1 The friction plate can be selected from a commonly used eight-tooth structure, so that the first tooth groove and the second tooth groove each have eight teeth, and are arranged at equal intervals in the circumferential direction. Two adjacent ring teeth of the same friction plate are spaced 45° in the circumferential direction, and the adjacent first tooth groove and the second tooth groove on the inner wall of the assembly box 21 are spaced 22.5° in the circumferential direction.

[0041] In other embodiments, Figure 1 As shown, the locating sleeve 23 and the center hole on the lifting plate 11 are interference fit. More specifically, a rubber sleeve can be designed at the bottom of the locating sleeve 23 to cooperate with the center hole on the lifting plate 11, thereby ensuring that the lifting plate 11 and the locating sleeve 23 are coaxial, and the locating sleeve 23 and the locating rod 22 are coaxial, and the center sleeve assembly is coaxially mounted on the locating rod 22, so the coaxiality of the lifting plate 11 and the center sleeve assembly is guaranteed, thereby ensuring the assembly quality of the clutch.

[0042] Of course, there are other ways to achieve coaxial cooperation between the positioning sleeve 23 and the center hole on the lifting plate 11, such as providing a claw at the bottom of the center sleeve, which will not be described in detail here.

[0043] See also Figures 1 to 4 Based on the assembly method of the anti-mismatch device of a motorcycle clutch described above, we will give the step-by-step instructions for installing the clutch based on whether the first friction plate 15 and the second friction plate 17 are installed in place, which is specifically divided into three situations.

[0044] The first case, such as Figure 1 and Figure 2 As shown, if 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 first friction plate 15 can be snapped into the shallow groove of the outer cover in the subsequent assembly, and the second friction plate 17 can be snapped into the deep groove of the outer cover in the subsequent transfer, the assembly method includes the following steps:

[0045] S1: Like the prior art, we first assemble the clutch pressure plate 14, friction plate, driven plate 16 and center sleeve and other parts into a center sleeve assembly;

[0046] S2: Then the pressure plate 14 faces downward, and 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 buckled in the first tooth groove, and the second friction plate 17 is buckled 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 error-proofing pad 25 and the second friction plate 17 have no interference;

[0047] S3: Fit the spring 13 of the clutch onto the bolt 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 matched;

[0049] S5: Insert the bolt 12 from 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, and the sensor 26 detects the presence of the ring teeth of the friction plate in the first tooth groove. The sensor 26 controls the retraction of the positioning rod 22, and the lifting plate 11 presses the spring 13 downward until the lifting plate 11 and the bolt column are fitted together. The center sleeve assembly is fixed, and the bolt 12 is tightened. The first friction plate 15, the driven plate 16 and the second friction plate 17 will not slip. The role of the retaining ring 24 is similar to that of a gasket, ensuring that the first friction plate 15, the driven plate 16 and the second friction plate 17 are tightly fitted. 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 tightly fitted together.

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

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

[0053] S2: The pressure plate 14 faces downward, 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 buckled in the second tooth groove, the second friction plate 17 is buckled in the second tooth groove, the error-proofing pad 25 and the second friction plate 17 do not interfere with each other, but at this time there is no ring tooth of any friction plate in the first tooth groove;

[0054] S3: Then, the spring 13 of the clutch is mounted on the bolt 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 matched;

[0056] S5: Insert the bolt 12 from 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, and the sensor 26 detects that there is no ring tooth of the friction plate in the first tooth groove. The sensor 26 controls the positioning rod 22 to extend outward, and the center sleeve assembly cannot be fixed. The bolt 12 is tightened, and the first friction plate 15, the driven plate 16 and the second friction plate 17 are not tightly attached to each other, and slipping occurs naturally. In this case, the operator knows that the installation of the clutch is unqualified, and the clutch in the assembly box 21 is taken out;

[0058] S7: Reassemble the clutch.

[0059] The third case, such as Figure 1 and Figure 4 As shown, no matter the first friction plate 15 is installed in the first tooth groove or the second tooth groove, as long as the second friction plate 17 is installed in the first tooth groove, the gear ring of the second friction plate 17 cannot be snapped into the deep groove of the outer cover during the subsequent assembly process. The steps of the assembly method are as follows:

[0060] S1: Assemble the clutch pressure plate 14, friction plate, driven plate 16 and center sleeve into a center sleeve assembly;

[0061] S2: The pressure plate 14 faces downward, and the center sleeve assembly is installed into the assembly box 21. The positioning rod 22 passes through the center of the center sleeve assembly; the second friction plate 17 is buckled in the first tooth groove, and the anti-error 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 part of the assembly box 21 cannot be tightly attached, but the operator may not notice it;

[0062] S3: Fit the spring 13 of the clutch onto the bolt 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 matched;

[0064] S5: Insert the bolt 12 from 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 inner part of the assembly box 21 cannot be tightly attached, 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 be tightly attached. 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 naturally slip. In this case, the operator knows that the clutch is not installed properly and takes out the clutch in the assembly box 21.

[0066] S7: Reassemble the clutch.

[0067] Through the description of the above three situations, the present assembly method enables the operator to determine whether the ring teeth of the first friction plate 15 and the second friction plate 17 of the clutch are properly installed during the installation process according to whether there is slippage between the first friction plate 15, the driven plate 16 and the second friction plate 17 when the bolts 12 are tightened. If the installation position is wrong, the first friction plate 15, the driven plate 16 and the second friction plate 17 slip when the bolts 12 are tightened, the operator reinstalls the various components of the clutch, thereby avoiding the installation angle of the second friction plate 17 being staggered to the position of the shallow groove of the outer cover, or the installation angle of the first friction plate 15 being staggered to the position of the deep groove of the outer cover, resulting in the subsequent components cannot be smoothly installed in place, affecting production efficiency and product quality.

[0068] To sum up, the anti-mismatch device of the present invention is designed with an anti-mismatch pad 25 and a sensor 26 in the first tooth groove, so 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, the driven plate 16 and the second friction plate 17 of the clutch loaded in the assembly box 21 cannot be completely close to each other, so that when the bolts 12 of the clutch are tightened, slippage will occur between the first friction plate 15, the driven plate 16 and the second friction plate 17. The operator reinstalls the clutch accordingly and adjusts the positions of the ring teeth of the first friction plate 15 and the ring teeth of the second friction plate 17, thereby solving the problem in the prior art that during the installation and production process of the clutch, the operator is prone to misalign the installation angle of the second friction plate 17 to the position of the shallow groove of the outer cover, or misalign the installation angle of the first friction plate 15 to the position of the deep groove of the outer cover, resulting in the subsequent parts cannot be smoothly installed in place, affecting production efficiency and product quality. At the same time, the anti-mismatching device also ensures the coaxiality between the clutch center sleeve assembly and the lifting plate 11 by coaxially fitting the positioning sleeve 23 on the positioning rod 22, and the positioning sleeve 23 and the center hole on the clutch lifting plate 11 are coaxially matched, thereby improving the assembly quality of the product. The assembly method of the present invention enables the operator to determine whether the ring teeth of the first friction plate 15 and the second friction plate 17 are installed properly according to whether the first friction plate 15, the driven plate 16 and the second friction plate 17 of the clutch slip when the bolt 12 is tightened during the installation process. If the installation position is wrong, the first friction plate 15, the driven plate 16 and the second friction plate 17 slip when the bolt 12 is tightened, and the operator reinstalls the various components of the clutch, thereby avoiding the installation angle of the second friction plate 17 being staggered to the position of the shallow groove of the outer cover, or the installation angle of the first friction plate 15 being staggered to the position of the deep groove of the outer cover, resulting in the problem that the subsequent components cannot be installed smoothly, affecting the production efficiency and product quality. Therefore, the present invention effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

[0069] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may 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 a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
