Description

Technical Field

[0001] The embodiments of this utility model belong to the field of automotive repair training, and more specifically, relate to a mobile training platform that displays the internal structure using original vehicle clutch system components. Background Technology

[0002] The clutch system is a crucial component of a car's transmission system, its primary function being to establish a controllable connection between the engine and the transmission. In manual transmission vehicles, the clutch allows the driver to control the connection and disconnection between the engine and the transmission via a pedal, enabling gear shifting and starting. Due to wear and tear on the connection, the clutch system requires frequent maintenance and repair, necessitating a large number of mechanics familiar with its mechanical structure and operating principles for routine maintenance and troubleshooting.

[0003] Traditional maintenance data and training materials are primarily paper-based, resulting in a limited and unintuitive information delivery method. Hands-on training with actual vehicles is costly, and understanding the working principles requires operation and observation from different locations such as inside the vehicle, engine compartment, and under the vehicle. Teaching the internal structure requires disassembling and dismantling the clutch and transmission assemblies from the vehicle, which is extremely time-consuming. Therefore, the design of a clutch system training platform requires collaboration between engineers with accurate knowledge of the clutch system structure and instructors familiar with the training process.

[0004] The clutch system training platform is a device specifically designed for teaching and training. It simulates the working principle and operation process of an automotive clutch, helping students and technicians better understand the structure and function of the clutch system. If traditional textbooks combined with hands-on practice are used to train maintenance personnel, fully mastering the structure and principles of the Mengshi B platform parking brake system would require a significant amount of time and resources.

[0043] The working principle is as follows:

[0044] First, the outer transmission shaft assembly (not shown in the figure) is designed to be extended, and it is extended to 110 mm. Then, the clutch housing 3 is fixed on the overall support 6 by a special support, and the clutch assembly is sequentially composed of a clutch driven plate, a clutch pressure plate 13, a release bearing, a release guide sleeve, a clutch release fork, a transmission shaft end cover, a transmission shaft assembly, a transmission shaft bearing (the structure of the clutch assembly is conventional, so its structure is not described in detail). The transmission shaft assembly, the transmission shaft end cover and the transmission shaft bearing are sequentially fixed and connected and fixed to the overall support 6. The release bearing is installed on the release bearing guide sleeve, and the clutch release fork is arranged on one side of the release bearing guide sleeve and is fixed on the clutch housing 3. The flywheel plate 14, the clutch driven plate and the clutch pressure plate 13 are sequentially connected and connected with the transmission shaft assembly. The flywheel housing 2 is connected with the clutch housing 3, and the clutch input shaft hand wheel 1 is fixed to the flywheel housing 2. The inside of the flywheel plate 14 is provided with 8 bolt holes, which are connected with a special fixing plate and fixedly connected with the clutch pressure plate 13. The clutch driven plate is provided with a spline hole which can slide on the spline of the transmission shaft assembly in the center, and the clutch driven plate is connected with the transmission shaft assembly through the spline hole. The air cylinder assembly 11 serves as a high-pressure gas storage container. When the clutch pedal 9 is stepped on, the hydraulic pump oil pressure pushes away the clutch booster air pressure valve, and the air pressure drives the clutch. The clutch pressure plate 13 and the clutch pressure cover are connected by a plurality of groups of transmission pieces distributed around to transmit torque. The clutch pedal 9 is located in the front left of the training table, and the release lever at the connection between the clutch pedal 9 and the clutch release fork is provided with a clutch booster. After stepping on the clutch pedal 9, the hydraulic pump delivers oil pressure to the clutch booster assembly, the clutch booster assembly opens the air valve port, high-pressure gas enters the clutch booster, thereby driving the release lever to move and work, and the release lever drives the clutch release fork to move. The overall support 6 is spliced by 60 mm aluminum profiles, and the bottom of the overall support 6 is fixed with a nylon directional wheel 8 and a nylon universal wheel 10 by screws. At the same time, the clutch housing 3 and the clutch inside are fixed on the overall support 6 by a special fixing support. In order to facilitate the observation of the internal structure of the clutch and the action process, the clutch housing 3 and the flywheel housing 2 are cut by a numerical control machine to form a trapezoidal observation port with a length of about 1 / 5, and a transparent observation window is provided, so that students can directly observe the internal structure and working state of the clutch, thereby deepening the impression and understanding of the working principle of the clutch system.

[0045] In the working process of the training table, the clutch input shaft hand wheel 1 simulates power input, and the clutch input shaft hand wheel 1 is rotated by hand to drive the driving shaft to rotate, and the inner group bolt holes of the flywheel disc 14 are fixed with the driving shaft, so as to drive the flywheel disc 14 to rotate. The outer group bolt holes of the flywheel disc 14 are used for installing the clutch pressure plate 13, and at this time, the torque of the driving wheel is transmitted to the clutch driven plate by the friction of the contact surface of the flywheel disc 14 and the clutch driven plate. The clutch driven plate is a steel plate covered with a friction material, and a spline hole, which can slide on the spline of the transmission one shaft assembly, is arranged at the center of the clutch driven plate. The clutch pressure plate 13 is fixed on the flywheel disc 14, and the clutch pressure plate 13 is provided with a compression spring, and a radial notch is formed in the close-to-center part, so as to form an elastic lever. When the clutch pressure plate 13 is not fixed on the flywheel disc 14, the compression spring is not stressed, and is in a natural state without elastic force; when the clutch pressure plate 13 is fixed on the flywheel disc 14, the compression spring generates compression force, so that the clutch driven plate is clamped between the clutch pressure plate 13 and the flywheel disc 14, and the clutch driven plate, the clutch pressure plate 13 and the flywheel disc 14 rotate synchronously with the transmission one shaft assembly. Then, the clutch pedal 9 is stepped on, the hydraulic pump behind the clutch pedal 9 transmits oil pressure to the hydraulic control gas boosting device 4 through the oil pipe, the hydraulic control gas boosting device 4 opens the gas valve port, so that the high-pressure gas enters the clutch booster (which is a gas-driven thrust rod structure, and is a conventional structure, so it is not described in detail; the hydraulic control gas boosting device is responsible for the conversion from hydraulic pressure to gas pressure, and the overall gas pressure control and power transmission. The clutch booster assembly is the part directly connected with the separation rod and other components in the whole boosting system, and it operates under the gas pressure converted by the hydraulic control gas boosting device 4, so as to push the clutch separation yoke to move), so as to push the separation rod to work, the booster push rod pushes the clutch separation yoke to move, the two claws on the clutch separation yoke push the separation bearing guide sleeve to move on the driven shaft, and the separation bearing is arranged on the separation bearing guide sleeve and moves with the separation bearing guide sleeve. At this time, the clutch is in the separation state, in order to engage the clutch, the force acting on the clutch separation yoke gradually decreases, the separation bearing and the separation bearing guide sleeve move backward, and the clutch pressure plate 13 moves backward to clamp the clutch driven plate between the clutch pressure plate 13 and the flywheel disc 14.

[0046] In summary, the clutch operation process of the actual vehicle is simulated, so that the students can intuitively observe the internal structure and working state change of the clutch, master the operation skill and working principle of the clutch system, further consolidate the training knowledge, and improve the efficiency of automobile maintenance training.

[0047] Those skilled in the art can easily understand that the above description is only a preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
