Technical Field

[0001] This utility model relates to the field of sensor detection technology, specifically to a device for detecting the damping characteristics of a wet multi-plate clutch. Background Technology

[0002] The wet multi-plate clutch damping characteristic testing equipment is a core testing tool in the motorcycle transmission system manufacturing field. Its core function is to accurately collect key parameters such as damping force, displacement, and speed of the clutch damping spring at different working angles, and generate damping characteristic curves. This solves the problems of low efficiency, large data dispersion, and inability to meet the performance requirements of high-end clutches in traditional testing methods.

[0003] The testing equipment consists of a test host, transmission system, force measuring system, control system, safety protection device, and foot device. The clutch assembly to be tested is installed in an adjustable fixture. The equipment drives the assembly to operate according to preset parameters, and synchronously collects torque and displacement data at different angles. The software analyzes the data to generate characteristic curves and automatically determines the product's qualification.

[0004] When matching wet clutches to high-end motorcycles with large displacement engines, the high horsepower of these clutches places extremely high demands on the smoothness of clutch shifting. Therefore, it is necessary to quickly test the damping characteristic curves of the clutch damping spring at different working angles. In view of this, we propose a wet multi-plate clutch damping characteristic testing device. Utility Model Content

[0005] The purpose of this invention is to provide a wet multi-plate clutch damping characteristic testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wet multi-plate clutch damping characteristic testing device includes a working platform, a push-button switch on the working platform, movable feet fixedly installed at the bottom of the working platform, and a testing component on the working platform, the testing component comprising: A mounting plate is fixedly mounted on the working platform.

A measuring amplifier is fixedly mounted on the sliding frame, a movable end torque sensor is fixedly mounted on the sliding frame, a movable end clamping module is provided on the movable end torque sensor, and a handle is fixedly mounted on the sliding frame.

[0007] In a further embodiment, multiple sets of slide rails and sliders are provided, and the measuring amplifier is connected to the moving end torque sensor.

[0009] In a further embodiment, the grip is positioned behind the torque sensor on the mobile end, and an anti-slip sleeve is fitted onto the grip.

[0010] In a further embodiment, the mounting plate is provided with an auxiliary component, which includes a rubber block. The rubber block is fixedly mounted on the sliding frame, and an mounting block is fixedly mounted on the mounting plate. A rubber sleeve is fixedly mounted on the mounting block.

[0013] Compared with the prior art, this utility model provides a wet multi-plate clutch damping characteristic testing device, which has the following beneficial effects: 1. This wet multi-plate clutch damping characteristic testing equipment is designed to meet the high-precision testing requirements of high-end motorcycle clutches. It incorporates a testing component that, in conjunction with a motor, drives a fixed-end torque sensor via a reducer. The fixed and moving-end clamping modules hold the clutch, preventing slippage and displacement during testing. Dual torque sensors simultaneously collect damping force data at different angles. The amplified signals are then transmitted to the control system, enabling the fusion processing of multiple parameters including torque, torsion angle, and rotational speed. The slider can adjust the distance between the two clamping modules by sliding along the guide rail, adapting to the testing of clutches of different specifications.

[0014] 2. In order to adapt the device to the high-frequency operation requirements of batch clutch testing, the wet multi-plate clutch damping characteristic testing equipment is equipped with an auxiliary component. When the sliding frame moves to the rear limit distance, the component, together with the rubber block and rubber sleeve, collide and buffer to offset the sliding inertia of the slider and avoid rigid impact between the clamping module and the clutch. At the same time, when the sliding frame moves to the front limit distance, the spring pushes the round rod and the impact block to slide along the sliding groove. The impact block and the limit block buffer to prevent the sensor from being damaged due to the vibration of the sliding frame. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0019] Please see Figures 1-5 This utility model provides a technical solution: A wet multi-plate clutch damping characteristic testing device includes a working platform 1, a push-button switch 2 on the working platform 1, and a movable foot 3 fixedly installed at the bottom of the working platform 1.

[0020] In one embodiment of this utility model, a test component 4 is provided on the work platform 1. The test component 4 includes a mounting plate 41, which is fixedly mounted on the work platform 1. A support frame 42 is fixedly mounted on the mounting plate 41. A reducer 43 is fixedly mounted on the support frame 42. A motor 44 is fixedly mounted on one end of the reducer 43. A fixed-end torque sensor 45 is fixedly mounted on the other end of the reducer 43. A fixed-end clamping module 46 is provided on the fixed-end torque sensor 45. A slide rail 47 is fixedly mounted on the mounting plate 41. A slider 48 is slidably mounted on the slide rail 47. A sliding frame 49 is fixedly mounted on the slider 48. Amplifier 410 is fixedly mounted on sliding frame 49. A movable torque sensor 411 is fixedly mounted on sliding frame 49. A movable clamping module 412 is provided on movable torque sensor 411. A handle 413 is fixedly mounted on sliding frame 49. Multiple sets of slide rail 47 and slider 48 are provided. Measurement amplifier 410 is connected to movable torque sensor 411. Movable torque sensor 411 and movable clamping module 412 are directly opposite fixed torque sensor 45 and fixed clamping module 46. Handle 413 is located behind movable torque sensor 411. Anti-slip sleeve is provided on handle 413.

[0021] In this embodiment, before testing, the clamping distance is adjusted according to the specifications of the wet multi-plate clutch to be tested: Hold the handle 413 with the anti-slip sleeve, push the sliding frame 49 to drive the slider 48 to slide along multiple sets of slide rails 47 until the distance between the fixed end clamping module 46 and the moving end clamping module 412 matches the clutch size. Then, fix both ends of the clutch onto the two sets of clamping modules respectively to ensure a firm clamping and prevent slippage during testing. Adjust the test parameters using the button switch 2 to start the testing process: The motor 44 rotates, and after the speed is adjusted by the reducer 43 on the support frame 42, it drives the fixed end torque. The sensor 45 rotates, which in turn drives the clutch to rotate synchronously. During the rotation process, the fixed-end torque sensor 45 and the moving-end torque sensor 411 synchronously collect damping force data of the clutch at different working angles. The signal collected by the moving-end torque sensor 411 is amplified by the measuring amplifier 410 and transmitted to the control system together with the data from the fixed-end sensor. The control system uses an intelligent data analysis algorithm to achieve the fusion processing of multiple parameters such as torque, torsion angle, and speed, generate a dynamic damping characteristic curve in real time, automatically identify curve features, calculate key indicators such as torsional strength and peak value, and determine whether the product quality is qualified.

[0022] In one embodiment of this utility model, an auxiliary component 5 is provided on the mounting plate 41. The auxiliary component 5 includes a rubber block 51. The rubber block 51 is fixedly installed on the sliding frame 49. The mounting block 52 is fixedly installed on the mounting plate 41. The rubber sleeve 53 is fixedly installed on the mounting block 52. The limit block 54 is fixedly installed on the slide rail 47. The slider 48 is provided with a sliding groove 55 and a mounting groove 56. One end of the spring 57 is fixedly installed inside the slider 48, and the other end of the spring 57 is fixedly installed with a round... An impact block 59 is fixedly installed at one end of the rod 58 and the other end of the round rod 58. There are multiple sets of rubber blocks 51, mounting blocks 52, rubber sleeves 53, limiting blocks 54, sliding grooves 55, mounting grooves 56, springs 57, round rods 58 and impact blocks 59. The multiple sets of rubber blocks 51 and multiple sets of rubber sleeves 53 are positioned correspondingly. The springs 57 are set inside the mounting grooves 56. The round rods 58 slide inside the mounting grooves 56. The impact blocks 59 slide inside the sliding grooves 55. The impact blocks 59 are directly opposite the limiting blocks 54.

[0023] In this embodiment, when adjusting the clamping distance or pulling the sliding frame 49 to reset after detection, if the sliding frame 49 moves to the rear limit distance, the rubber block 51 on the sliding frame 49 will collide with the rubber sleeve 53 on the mounting block 52. The elastic properties of the rubber will offset the inertial impact force of the sliding slider 48, avoiding rigid collision between the clamping module and the clutch, and protecting the clutch and sensor from damage. When the sliding frame 49 moves forward to the front limit distance, the impact block 59 on the slider 48 will contact the limit block 54 on the slide rail 47. At this time, the spring 57 in the mounting groove 56 is compressed, pushing the round rod 58 to drive the impact block 59 to slide along the sliding groove 55. The elastic deformation of the spring 57 buffers the impact force, preventing the torque sensor from being damaged due to inertial vibration of the sliding frame 49.
