Description

A Clutch Dynamic Visualization Maintenance Training Device Technical Field

[0001] This utility model belongs to the field of automotive teaching equipment technology, specifically relating to a clutch dynamic visualization maintenance training device. Background Technology

[0002] In the field of automotive repair education, the structural principles and maintenance training of clutch systems is an essential part of vocational education. Currently, the industry commonly uses static disassembly and assembly models or enclosed training platforms for teaching. These traditional methods have significant drawbacks: firstly, clutch hydraulic lines are mostly made of metal, making it impossible for students to directly observe the oil flow path and pressure transmission process; secondly, key mechanical components such as the pressure plate and release bearing are completely obscured by the outer casing, allowing only a partially dissected static model to demonstrate the structure, and failing to dynamically present the mechanical linkage process during clutch engagement and disengagement.

[0003] The prior art, disclosed in application number CN201610521723.5, is a training device for a manual transmission with a clutch. Although this training device can demonstrate the electrical parameter testing and mechanical operation of the transmission after disassembly and assembly, the clutch hydraulic circuit in this training device still adopts a traditional closed design. The oil flow state and the operation process of the slave pump cannot be visualized. It does not involve the simulation of the maintenance process of the clutch hydraulic system, such as the teaching of oil change and venting operations or injection of typical fault scenarios such as air resistance and oil leakage. It is difficult to meet the core needs of clutch maintenance teaching.

[0004] Therefore, how to achieve full-process visual teaching of clutch structure principles and maintenance processes has become an urgent problem to be solved in vocational education. This can not only effectively improve students' understanding of the complex mechanism of the clutch system and their practical skills, but also fill the gap in dynamic demonstration and interactive training in the teaching of dynamic clutch systems, thereby cultivating high-quality technical talents who are more in line with the needs of the modern automotive repair industry. Summary of the Invention

[0005] To address the problems in clutch training, such as the lack of visualization of the dynamic process of the hydraulic system, limited simulation functions for maintenance procedures, and insufficient safety interaction design, which make it difficult for trainees to grasp the systematic knowledge of "hydraulic circuit drive-mechanical response," this invention provides a clutch dynamic visualization maintenance training device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a dynamic visualization maintenance training device for clutches, comprising a frame body and a demonstration platform mounted thereon. The frame body is equipped with lockable casters. A clutch master cylinder is mounted on the demonstration platform. On the front of the demonstration platform, a clutch assembly, a drive motor, and a clutch slave cylinder are mounted via brackets. The drive motor simulates engine output power, and its output shaft is connected to the flywheel of the clutch assembly. The clutch slave cylinder uses an electric push rod to perform the driving action, and the end of the push rod is connected to the release fork of the clutch assembly. By driving the release fork to swing around its pivot point, the release bearing is moved, completing the dynamic simulation of the clutch disengagement process. A running light strip is arranged between the clutch master cylinder and the clutch assembly, replacing hydraulic pipeline connections. A disengagement switch, an oil change switch, and a fault switch are mounted on the front of the demonstration platform, and a [missing information - likely a device name or function] is mounted on the back of the demonstration platform. The system includes a power conversion module, a power transformer module, an interlock module, a relay module, and a light strip controller. An external 220V AC power supply is split into two paths via a leakage current protector. One path directly powers the drive motor, while the other path, after being converted to 12V DC by the power conversion module, supplies power to the clutch master cylinder, clutch slave cylinder, interlock module, and relay module in parallel. The light strip controller is connected to the power conversion module via the power transformer module, providing it with a 5V low-voltage power supply. The disconnect switch, oil change switch, and fault switch are connected in series in the three-way control circuit between the power conversion module and the interlock module. The interlock module contains three relays, whose outputs are connected to the signal inputs of the light strip controller. The signal outputs of the light strip controller are connected to the running light strip to control its flashing frequency and color changes. The signal inputs of the relay modules are connected to the control circuit of the disconnect switch, and the signal outputs of the relay modules control the start and stop of the clutch master cylinder and clutch slave cylinder.

[0007] As a further supplement to the above technical solution, a manual separation observation device is installed on the front of the demonstration stand. The manual separation observation device includes a shift fork handle, a separation shift fork and a separation bearing driven by a mechanical linkage structure, and the shift fork handle is used to realize the manual demonstration of the release of the clutch pressure plate spring.

[0008] As a further supplement to the above technical solution, a two-dimensional planar schematic diagram of clutch disengagement is provided on the front of the demonstration stand.

[0009] As a further supplement to the above technical solution, a display module is provided on the front of the demonstration stand, which is used to display comparison parts of new, worn, and deformed clutch plates.

[0010] As a further supplement to the above technical solution, a panel ambient light and a title backlight are installed on the front of the demonstration stand, and both are powered by a power conversion module. The panel ambient light is arranged on the front edge of the demonstration stand, and the title backlight is arranged in the title area.

[0011] As a further supplement to the above technical solution, a remote control module is installed on the back of the demonstration stand and is powered by a power conversion module. The remote control module is connected in parallel in the control circuits of the clutch disengagement switch, the oil change switch, and the fault switch. The remote control module is wirelessly connected to a handheld remote controller for remotely controlling clutch disengagement, oil change, and simulating fault conditions.

[0012] As a further explanation and limitation of the above technical solution, the flowing light strip is inserted into a transparent flexible tube, the two ends of which are fixed between the clutch master cylinder and the clutch assembly mechanism, and the middle part is fixed to the front of the demonstration stand by a buckle.

[0013] As a further explanation and limitation of the above technical solution, the friction plates and pressure plate components of the clutch assembly adopt a partially transparent or dissected structure, which facilitates intuitive observation of the internal working state and wear of the clutch.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This invention simplifies the hydraulic system and reduces maintenance by using a running light strip threaded through a transparent flexible tube to connect the clutch master cylinder and the slave cylinder of the clutch assembly, replacing the hydraulic lines. Furthermore, an electric push rod replaces the slave cylinder, simplifying the hydraulic system and reducing maintenance difficulties. Additionally, the friction plates and pressure plate components of the clutch assembly are partially transparent or have a dissected structure. The running light strip, in conjunction with the electric push rod, drives the release fork to move the release bearing, dynamically simulating the clutch disengagement process. This allows trainees to directly observe the internal workings of the clutch, enhancing the demonstration's intuitiveness and interactivity, and effectively solving the problem of invisible hydraulic movements in traditional training devices.

[0016] 2. This utility model features a manual separation observation device, a two-dimensional display of the clutch separation diagram, and a display module on the front of the demonstration stand. The manual shift fork handle drives the separation shift fork and the separation bearing. Combined with the structural analysis of the two-dimensional diagram and the comparative display of new, worn, and deformed clutch plates, it helps trainees to deeply understand the mechanical linkage principle of clutch separation and the influence of component status on clutch performance.

[0017] 3. This utility model integrates panel ambient light, title backlight and remote control module. The ambient light and backlight enhance the visual recognition of the demonstration area. The remote control module enables remote control of clutch disengagement, oil change and fault simulation, which greatly enhances the interactivity of the teaching scenario and enables students to master fault diagnosis skills in hands-on practice.

[0018] 4. This utility model adopts a lockable universal wheel, integrates various module electrical control systems and leakage protection design. It converts 220V AC power to 12V DC power and 5V low voltage power through a power conversion module. The low voltage DC and leakage protection device ensure teaching safety.

[0022] To further illustrate the technical solution of this utility model, taking the Beijing BJ80 clutch as an example, and referring to Figures 1-2, the following four embodiments will further explain this utility model.

[0023] The clutch master cylinder, clutch assembly mechanism, and manual disengagement observation device involved in this example are all physical models, and since they are all existing technologies, their specific structures are not described in detail. The clutch slave cylinder uses an electric push rod to simulate the actuator, and a running light strip replaces the original hydraulic lines connecting the clutch master cylinder and clutch slave cylinder. The table below shows the basic information of the key components and modules procured in this example, facilitating quick understanding and application by those skilled in the art.

[0024] Specifications: Electric actuator, stroke 20mm (with wings), speed / torque 8mm / s (80N / 8KG), voltage DC12V; drive motor: permanent magnet synchronous motor, 15 revolutions / minute, power 28W; center output shaft 8mm; holeless running light strip, ultra-narrow patch multicolor flexible light strip, 5V / WS2812B, 4mm light strip controller with 5V running light strip leakage protection 1P+N25A; power conversion module S-120-12, 12V 10A power transformer module MK-1052, 24V / 12V to 5V 3A interlock module containing three relays, connected to 12V circuit, control light strip signal input relay module; five-claw relay JD194, 12V 80A, with relay socket; remote control module: 12V four-way remote control switch + medium power remote control, connected in parallel to manual switch control circuit. Table Example 1

[0025] As shown in Figure 1, a dynamic visualization maintenance training device for clutches includes a frame body 1 and a demonstration platform 2. Lockable casters 3 are installed on the frame body 1. The clutch assembly 6, drive motor 7, and electric push rod are all fixed to the demonstration platform 2 via brackets 5. The drive motor 7 simulates engine output power, and its output shaft is connected to the flywheel of the clutch assembly 6. The push rod end is connected to the release fork of the clutch assembly 6. By driving the release fork to swing around its fulcrum, the release bearing is moved, completing the dynamic simulation of the clutch disengagement process. The clutch master cylinder 4 is installed on the demonstration platform 2, and a flowing light strip 9 is arranged between the clutch master cylinder 4 and the clutch assembly 6. The flowing light strip 9 is threaded through a transparent flexible tube, with both ends of the transparent flexible tube fixed to the clutch master cylinder 4 and the clutch assembly 6 at two different locations. The middle part of the transparent flexible tube is fixed to the front of the demonstration platform 2 by a clip. A disengagement switch 10, an oil change switch 11, and a fault switch 12 are installed on the front of the demonstration platform 2. The back of demonstration stand 2 is equipped with a power conversion module, a power transformer module, an interlock module, a relay module, and a light strip controller.

[0026] As shown in Figure 2, the external 220V AC power supply is protected by a residual current device (RCD) 13. When a leakage or short circuit occurs, the RCD automatically cuts off the power supply to ensure teaching safety. Of course, the PE wire in the circuit is connected to the main frame 1 to ensure reliable grounding of the equipment's metal components and prevent the risk of leakage. The output of the leakage current protector 13 is divided into two paths. One path directly powers the drive motor 7, and the other path is converted to 12V DC by the power conversion module and then connected in parallel to power the clutch master pump 4, clutch slave pump 8, interlock module, and relay module through branch circuits. The disconnect switch 10, oil change switch 11, and fault switch 12 are connected in series in the three-way control circuit between the power conversion module and the interlock module. The interlock module contains three relays, and the output of each of the three relays is connected to the signal input of the light strip controller. The closing / opening of the relay contacts controls the output signal of the light strip controller. The 12V DC is converted to 5V DC by the power transformer module to power the light strip controller. The signal input of the light strip controller receives the relay signal from the interlock module, and the output is connected to the flowing light strip 9. The different signals from the light strip controller control the flashing frequency and color change of the flowing light strip 9 to achieve dynamic demonstration. The signal input terminal of the relay module is connected in series in the control circuit of the disengagement switch 10. When the disengagement switch is pressed, the relay module is triggered, and its output terminal controls the start and stop of the clutch master pump 4 and the clutch slave pump 8 to realize the electric drive of clutch disengagement.

[0027] Furthermore, the friction plates and pressure plate components of the clutch assembly 6 adopt a partially transparent or dissected structure, facilitating direct observation of the clutch's internal working condition and wear. Example 2

[0028] Traditional training devices can only demonstrate the clutch structure through static anatomical models, making it difficult for trainees to understand the dynamic linkage between the release fork, release bearing, and pressure plate. Therefore, a manual separation observation device and a two-dimensional diagram were added. By combining mechanical linkage demonstrations with planar illustrations, the teaching loop of operation-observation-understanding is strengthened, enabling trainees to intuitively grasp the mechanical principles of clutch disengagement.

[0029] As shown in Figure 1, a manual disengagement observation device 14 and a clutch disengagement diagram 15 are installed on the front of the demonstration stand 2. The manual disengagement observation device 14 includes a shift fork handle, a disengagement shift fork driven by a mechanical linkage structure, and a disengagement bearing. The shift fork handle allows manual operation to demonstrate the clutch pressure plate spring release process, enabling trainees to more intuitively understand the dynamic process of clutch disengagement and engagement. The clutch disengagement diagram 15 visually displays the internal structure and working principle of the clutch in a two-dimensional plane.

[0030] Furthermore, a display module 16 is provided on the front of the demonstration stand 2 to display new, worn, and deformed clutch discs for comparison, with relevant parameters and names labeled to facilitate a direct understanding of the impact of each component's condition on clutch performance. Example 3

[0031] Traditional teaching methods lack a visual demonstration of clutch wear. To enhance the visibility of the demonstration area in a dark environment, we added a lighting system that visually echoes the flowing light strips, highlighting the teaching title and supporting the multimedia teaching scenario.

[0032] As shown in Figures 1 and 2, a panel ambient light 17 and a title backlight 18 are installed on the front of the demonstration stand 2. The panel ambient light 17 is arranged at the edge of the front of the demonstration stand 2, and the title backlight 18 is arranged in the title area. Both are connected in parallel to a 12V circuit, powered by a power conversion module branch, and controlled by a leakage current protector 13. Example 4

[0033] To address the issues of limited operating perspective and cumbersome fault simulation procedures in multi-person teaching scenarios, and the inability to demonstrate dynamic fault scenarios via button switches, a remote control module was added to the button switch design to wirelessly control clutch disengagement, oil change, and simulate fault states.

[0034] As shown in Figure 2, a remote control module is installed on the back of the demonstration stand 2, powered by a power conversion module. The remote control module is connected in parallel to the control circuits of the disengagement switch 10, the oil change switch 11, and the fault switch 12. The signal output terminal of the remote control module forms a parallel control loop with the manual push-button switch. The remote control module wirelessly connects to a handheld remote control, which has three function buttons corresponding to "Disengagement," "Oil Change," and "Fault." After receiving a signal, the remote control module closes its internal relay contacts, replacing the on / off state of the manual switch, thus achieving the same logic control. This forms a dual control mode of manual push-button + remote control. This design allows teachers to flexibly operate the demonstration from different positions, improving teaching interactivity and efficiency. Students can quickly grasp the operating essentials of the clutch in various states through intuitive observation, enhancing their practical skills.

[0035] Detailed operation method and demonstration process:

[0036] System initialization: Connect to 220V power supply, turn on leakage protection device 13, panel ambient light 17 and title backlight 18 automatically light up, drive motor 7 drives flywheel to rotate, flowing light strip 9 is constantly green to simulate hydraulic oil flow, simulating clutch engagement state.

[0037] 2. Separation Simulation Demonstration: Press the separation switch 10 or the remote control "Separate" button, the relay module starts the master pump 4 and slave pump 8 (i.e., electric push rod), the electric push rod drives the separation fork, the separation bearing presses down the clutch pressure plate, the flywheel spins freely, and the gearbox input shaft stops rotating; after releasing the separation switch 10 or the remote control "Separate" button, the pressure plate resets, and the clutch engages.

[0038] 3. Manual disengagement operation: When explaining the transmission principle with reference to the clutch disengagement diagram 15, manually operate the disengagement observation device 14 shift fork handle to observe the mechanical process of the disengagement shift fork driving the disengagement bearing to move.

[0039] 4. Oil change simulation: Press the oil change switch 11 or the remote control "oil change" button, and the running light strip 9 will flash green in a cycle to simulate the liquid circulation and oil change process in the pipeline.

[0040] 5. Fault simulation and troubleshooting: Press fault switch 12 or remote control "fault" button, the running light strip 9 will flash yellow and green alternately, the pump 8 will move abnormally, and the electric push rod will not respond. Students need to observe the abnormal path of the light strip to teach fault identification and troubleshooting.

[0041] 6. Wear Comparison Teaching: With the clutch disengaged, observe the contact area between the friction plate and the pressure plate inside the transparent clutch assembly mechanism 6. Compare the thickness reduction and surface ablation marks of the clutch plate in module 16 to understand the fault logic of clutch plate wear / deformation → clutch slippage. This will enable students to gain a deeper understanding of the functions and fault manifestations of each clutch component and improve their fault diagnosis and troubleshooting abilities.

[0042] 7. System Reset: Turn off the leakage current protector 13, turn off the panel ambient light 17 and the title backlight 18, stop the drive motor 7 from rotating, the flywheel gradually stops, and the equipment enters the standby state.
