Description

Technical Field

[0001] The invention belongs to the technical field of continuously variable transmission detection equipment, and in particular relates to a working condition testing device and a testing method for a primary clutch of a motorcycle. Background Art

[0002] The continuously variable transmission is currently widely used in the transmission system of motorcycles. It uses a transmission belt and a master and driven wheel with variable working diameters to transmit power, and can achieve continuous changes in the transmission ratio, thereby obtaining the best match between the transmission system and the engine operating conditions.

[0003] The continuously variable transmission includes components such as the front pulley clutch, the rear pulley clutch and the starter disc. The front pulley clutch is also called the primary clutch in daily production. It is mainly responsible for transmitting power. It is located at the front end of the scooter transmission case and consists of a pulley disc and a pulley bead. The pulley disc consists of two discs, and the pulley bead is close to the inner side of the pulley disc at idle speed. The starter disc refers to the driving wheel set and the driven wheel set in the continuously variable transmission. They are composed of a movable cone disc and a fixed cone disc. The continuously variable transmission realizes the continuous change of the transmission ratio by moving the movable cone discs of the driving wheel set and the driven wheel set axially on the driving and driven shafts.

[0004] Before the primary clutch is installed on the motorcycle, it is necessary to perform a working condition test on the cooperation between it and the starting plate. The method adopted in the prior art is to directly install the primary clutch on the motorcycle for testing. Each test requires the entire motorcycle to work together, resulting in a waste of resources. At the same time, as the test progresses, the performance of the motorcycle changes as the motorcycle is used for an increased period of time. The test conditions cannot be guaranteed to be completely consistent, which results in a certain error in the operator's judgment of the test results. Summary of the invention

[0006] To achieve the above-mentioned purpose and other related purposes, the present invention provides a working condition testing device for a primary clutch of a motorcycle, comprising a power component and a simulated starting disk component, wherein the simulated starting disk component comprises a first limiting ring and a second limiting ring, both of which are rotatably arranged; the first limiting ring and the second limiting ring are connected by an elastic portion, a stop portion is arranged between the first limiting ring and the second limiting ring, and the outer side of the first limiting ring is in contact with the outer side of a moving disk of the primary clutch; the power component drives the primary clutch to rotate, and the moving disk moves outward under the action of the puli beads inside the primary clutch, and drives the first limiting ring to move toward the second limiting ring, and the elastic portion is compressed; the stop portion limits the moving distance of the first limiting ring.

[0007] Optionally, it also includes a positioning shaft; the main shaft of the primary clutch is fixedly mounted on the positioning shaft, the first limiting ring and the movable plate are both slidably mounted on the main shaft, and the second limiting ring is fixedly mounted on the positioning shaft; the power component drives the positioning shaft to rotate, driving the primary clutch and the second limiting ring to rotate, and the rotation of the primary clutch drives the first limiting ring to rotate.

[0008] Optionally, it also includes a first positioning plate and a second positioning plate; the first limiting plate is fixedly mounted on one end of the positioning shaft, and the other end of the positioning shaft is rotatably connected to the second positioning plate; the power component drives the first limiting plate to rotate, thereby driving the positioning shaft to rotate.

[0009] Optionally, it also includes a locking nut and an adjustment pad installed on the positioning shaft; the first positioning plate, the primary clutch, the second limiting ring, the adjustment pad, the locking nut and the second positioning plate are sequentially mounted on the positioning shaft.

[0010] Optionally, the stop portion is a step surface arranged on the inner side surface of the second limiting ring.

[0011] Optionally, the stop portion is a protrusion arranged on the second limiting ring toward the inside.

[0016] S1: selecting the simulated starting disk component according to the model of the primary clutch, and installing the primary clutch and the simulated starting disk component in sequence;

[0017] S2: starting the power component to drive the primary clutch to rotate to a specified speed;

[0018] S3: The puli beads generate centrifugal force as the primary clutch rotates, and the movable plate moves to the right under the centrifugal force of the puli beads, driving the first limiting ring to press the elastic part;

[0019] S4: the first limiting ring moves to a specified distance, and the stopper prevents the first limiting ring from moving further;

[0020] S5: After the first limiting ring stops moving for a specified time, the power component reduces the power output, the centrifugal force of the puli beads decreases, and the elastic part rebounds;

[0033] 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.

[0034] See also Figure 1 The present invention provides a working condition test device for a motorcycle primary clutch, including a power component and a simulated starting disk component 2. The simulated starting disk component 2 cooperates with the installation of a primary clutch 1 to simulate the movement state of the primary clutch 1 on the motorcycle. The primary clutch 1, as we are familiar with, includes a fixed disk 11, a movable disk 12, a main shaft 14 passing through the two disks, and a puli bead 13 installed between the two disks, which will not be described in detail here.

[0035] like Figure 1 As shown, the specific structure of the simulated starting disk component 2 includes a first limiting ring 21 and a second limiting ring 22 that are both rotatably arranged, the first limiting ring 21 and the second limiting ring 22 are connected by an elastic portion 23, a stop portion 24 is arranged between the first limiting ring 21 and the second limiting ring 22, the outer side of the first limiting ring 21 is in contact with the outer side of the moving disk 12 of the primary clutch 1; the power component drives the primary clutch 1 to rotate, and the moving disk 12 moves outward under the action of the puli beads 13 inside the primary clutch 1, and drives the first limiting ring 21 toward the second limiting ring The positioning ring 22 moves, and the elastic part 23 is compressed; the stop part 24 limits the moving distance of the first limiting ring 21; the first limiting ring 21 is driven by the moving disk 12 of the primary clutch 1 to compress the elastic part 23, and the stop part 24 limits the moving distance of the first moving ring, and then the elastic potential energy stored in the elastic part 23 is used to drive the moving disk 12 to move back, thereby simulating the entire movement of the primary clutch 1 in the motorcycle vehicle. The overall structure is simple and easy to assemble and produce; compared with the prior art of using a trailer vehicle to test the working condition of the primary clutch 1, resources are saved and costs are reduced.

[0036] The elastic part 23 can be a compression spring with suitable elastic force, and the power component can be a DC motor for easy movement, which will not be described in detail here.

[0037] In another embodiment, see Figure 1 , and also includes a positioning shaft 3; the main shaft 14 of the primary clutch 1 is fixedly mounted on the positioning shaft 3, the first limiting ring 21 and the movable plate 12 are both slidably mounted on the main shaft 14, and the second limiting ring 22 is fixedly mounted on the positioning shaft 3; the power component drives the positioning shaft 3 to rotate, driving the primary clutch 1 and the second limiting ring 22 to rotate, and the rotation of the primary clutch 1 drives the first limiting ring 21 to rotate. The design of the positioning shaft 3 provides reliable support for the primary clutch 1, the first limiting ring 21 and the second limiting ring 22. At the same time, the power component only needs to drive the positioning shaft 3 to rotate to drive the primary clutch 1, the first limiting ring 21 and the second limiting ring 22 to rotate together, thereby simplifying the structure of the entire working condition test device.

[0038] In another embodiment, see Figure 1, also includes a first positioning plate 4 and a second positioning plate 9; the first limit plate is fixedly mounted on one end of the positioning shaft 3, and the other end of the positioning shaft 3 is rotatably connected to the second positioning plate 9; the power component drives the first limit plate to rotate, thereby driving the positioning shaft 3 to rotate; the design of the first limit plate and the second limit plate ensures that the primary clutch 1 and the simulated starting plate component 2 installed on the positioning shaft 3 will not separate from the positioning shaft 3; at the same time, the first positioning plate 4 is driven to rotate by the power pickup to drive the rotation of the positioning shaft 3. Compared with the power component directly driving the positioning shaft 3 to rotate, the entire public test device will run more smoothly.

[0039] In another embodiment, see Figure 1 , also includes a locking nut 7 and an adjusting pad 6 installed on the positioning shaft 3; the first positioning plate 4, the primary clutch 1, the second limiting ring 22, the adjusting pad 6, the locking nut 7 and the second positioning plate 9 are sequentially mounted on the positioning shaft 3 against each other, so that the main shaft 14 of the primary clutch 1 and the second limiting ring 22 are fixedly installed on the limiting shaft; at the same time, the size of the adjusting pad 6 can be selected accordingly according to the size of the primary clutch 1 and the size of the simulated starting disk component 2.

[0040] In another embodiment, see Figure 1 The stop portion 24 is a step surface arranged on the inner side of the second limiting ring 22. This embodiment provides a design method for the stop portion 24. This structural form improves the structure of the second limiting ring 22 itself, that is, it can achieve the function of the stop portion 24 without adding new components.

[0041] In another embodiment, see Figure 1 The stopper 24 is a protrusion disposed on the second limiting ring 22 facing inward. This embodiment provides another design of the stopper 24, which will not be described in detail.

[0042] In another embodiment, see Figure 1 The first positioning plate 4, the main shaft 14 and the second limiting ring 22 are all connected to the positioning shaft 3 through a spline structure. The design of the first limiting plate, the primary clutch 1, the second limiting ring 22, the adjustment pad 6, the locking nut 7 and the second limiting plate abutting against each other in sequence not only ensures that the positions of the above-mentioned components are relatively fixed, but also facilitates the disassembly, assembly and replacement of the components.

[0043] In another embodiment, see Figure 1 , also includes a test bench, the power component and the second positioning plate 9 are fixedly mounted on the test bench to ensure the smooth operation of the entire working condition test device.

[0044] In another embodiment, see Figure 1 A deep groove ball bearing 8 is provided at the rotation connection between the positioning shaft 3 and the second positioning plate 9 to reduce the resistance encountered by the positioning shaft 3 when rotating in the second positioning plate 9, thereby improving the working efficiency of the working condition test device.

[0045] In other embodiments, Figure 1 As shown, the designer may also set a butterfly gasket 5 between the adjustment pad 6 and the second limiting ring 22, which will not be described in detail here.

[0046] See also Figure 1 and Figure 2 The testing method of the working condition testing device of the motorcycle primary clutch 1 described above comprises the following steps:

[0047] S1: According to the model of the primary clutch 1, the corresponding power component, the first positioning plate 4, the positioning shaft 3, the second positioning plate 9, the adjustment pad 6 and the simulated starting plate component 2 are selected. The power component can be a DC motor to facilitate movement, and then the DC motor is fixedly installed on the test bench, the first positioning plate 4 is connected to the output shaft of the DC motor, and then the positioning shaft 3 is installed on the first positioning plate 4; then, from left to right, the primary clutch 1 to be tested, the simulated starting plate component 2, the butterfly gasket 5 and the adjustment pad 6 are installed on the positioning shaft 3 in turn, and then the above-mentioned components are locked on the positioning shaft 3 with the locking nut 7, and then the tail end of the positioning shaft 3 is inserted into the second positioning plate 9. In order to reduce resistance, a deep groove ball bearing 8 is installed at the rotating connection between the second positioning plate 9 and the positioning shaft 3.

[0048] S2: After the components in the previous step are installed, the power component is started to drive the first positioning plate 4 to rotate. The first positioning plate 4 rotates, driving the positioning shaft 3 to rotate. The positioning shaft 3 rotates, driving the primary clutch 1 to rotate.

[0049] S3: As the power of the power component increases, the rotation speed of the primary clutch 1 gradually increases until the puli beads 13 inside the primary clutch 1 move radially outward under the action of centrifugal force, and the centrifugal movement of the puli beads 13 drives the moving plate 12 of the primary clutch 1 to move to the right, and then the moving plate 12 drives the first limiting ring 21 to move to the right, pressing the elastic part 23;

[0050] S4: As the first limiting ring 21 moves, the elastic portion 23 also stores the elastic potential energy until the first limiting ring 21 moves to the step surface of the second limiting ring 22, that is, moves to the stop portion 24. The first limiting ring 21 moves a specified distance because the step surface, that is, the stop portion 24, prevents the first limiting ring 21 from continuing to move. The specified distance is determined according to the model of the primary clutch 1 to be detected.

[0051] S5: After the first limit ring 21 stops moving for a specified time, which is generally 1 second, the power component reduces the power output, the speed of the first positioning plate 4 decreases, that is, the speed of the positioning shaft 3 decreases, and the speeds of all components on the positioning shaft 3 also decrease, and naturally the centrifugal force of the puli beads 13 inside the clutch is reduced;

[0052] S6: The elastic portion 23 gradually releases its elastic potential energy, and the first limiting ring 21 drives the movable plate 12 back to the initial position under the action of the resilience of the elastic portion 23; thus, a simulated working cycle of the primary clutch 1 ends;

[0053] S7: After that, the power component increases the power output, and the rotation speed of the primary clutch 1 increases again, and the primary clutch 1 starts a new round of working cycle. According to the detection standard, the working cycle can last for 5,000 times, 10,000 times, 20,000 times, etc.; after completing the working condition test of a primary clutch 1, the various components on the positioning shaft 3 are disassembled one by one. When the next primary clutch 1 is detected, it is considered whether to replace the entire simulated starting disk component 2 or replace the elastic part 23 of the simulated starting disk component 2 alone according to the specific situation.

[0054] In summary, the working condition test device of the primary clutch 1 of a motorcycle of the present invention simulates the design of the starting disk component 2, utilizes the first limiting ring 21 to compress the elastic part 23 after being driven by the moving disk 12 of the primary clutch 1, and the stop part 24 limits the moving distance of the first moving ring, and then utilizes the elastic potential energy stored in the elastic part 23 to drive the moving disk 12 to move back, so as to simulate the entire movement of the primary clutch 1 in the motorcycle vehicle, and the overall structure is simple and easy to assemble and produce; compared with the prior art using the trailer vehicle to test the working condition of the primary clutch 1, it not only saves resources but also reduces costs; the testing method of the present invention fully utilizes the advantages of the low cost and easy assembly and replacement of the simulated starting disk component 2 through the steps of the working condition test device design based on the primary clutch 1 of the motorcycle, ensures that each test of a primary clutch 1 can correspond to the use of a simulated starting disk component 2, ensures that the test conditions of a batch of primary clutches 1 of the same model can be consistent, and makes the operator's judgment on the test results more accurate. Therefore, the present invention effectively overcomes the shortcomings of the prior art and has a high industrial utilization value.

[0055] 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.
