[0024] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0025] The distribution mechanism simulation device of a special vehicle maintenance training simulator relates to the field of simulation training simulators. Its purpose is to invent a comprehensive simulation training device that has the same operating environment, the same fault phenomena, the same fault troubleshooting process, and the same physical and visual experience as the actual equipment, so that the crew can locate the fault point based on the fault phenomenon and carry out maintenance.

[0026] This invention patent discloses a distribution mechanism simulation device for a special vehicle maintenance training simulator, comprising a distribution mechanism simulation component and a drive box assembly, wherein the distribution mechanism simulation component is as follows: Figure 1 As shown,

[0027] The external components of the distribution mechanism simulation part include: an inner end cap (1.1), a limit bracket assembly (1.2), a distribution mechanism housing (1.3), a steering arm assembly (1.4), a clutch pointer sleeve (1.5), and a clutch scale plate (1.6);

[0028] The internal structure of the distribution mechanism simulation components, such as Figure 2 , 3 As shown, the simulated distribution mechanism internal components include: a clutch sleeve shaft assembly (2.1), a gear shift shaft assembly (2.2), an electromagnetic clutch (2.3), three gear meshing assemblies (2.4), an outer end cover (2.5), a gear shift disc assembly (2.6), a gear shift disc drive motor (2.7), a large gear meshing assembly (2.8), a bearing (2.9), a steering arm drive motor (2.10), and a clutch pointer drive motor (2.11).

[0029] Connection relationships of internal components in the distribution mechanism simulation component:

[0030] The first bearing (2.9) fixes the large gear in the first gear meshing assembly (2.4) onto the shaft of the clutch sleeve shaft assembly (2.1). Then, the large gear in the first gear meshing assembly (2.4) and the clutch scale plate (1.6) are connected by screws to fix their positions. The clutch scale plate (1.6) rotates with the rotation of the large gear in the first gear meshing assembly (2.4). The central shaft of the clutch pointer drive motor (2.11) is fixed together with the small gear in the first gear meshing assembly (2.4) by screws.

[0031] The large gear in the second gear meshing assembly (2.4) is fixed to the rotating shaft of the steering arm component (1.4) by the second bearing (2.9). The large gear in the second gear meshing assembly (2.4) and the limit frame assembly (1.2) are then connected by screws to fix their positions. The limit frame assembly (1.2) rotates with the rotation of the large gear in the second gear meshing assembly (2.4). The central rotating shaft of the steering arm drive motor (2.10) and the small gear in the second gear meshing assembly (2.4) are fixed together by screws.

[0032] The gear shift drive motor (2.7) is fixed to the gear shift assembly (2.6) via the third bearing (2.9). The small gear in the third gear meshing assembly (2.4) is fixed together with the rotating shaft of the gear shift assembly (2.6). The large gear in the third gear meshing assembly (2.4) is fixed to the gear shift shaft assembly (2.2). The gear shift shaft of the gear shift shaft assembly (2.2) passes through the center hole of the electromagnetic clutch (2.3). The electromagnetic clutch (2.3) is fixed to the distribution mechanism housing (1.3).

[0033] The large gear meshing assembly (2.8) is used to connect and fix the bearing (2.9), the outer end cover (2.5) and the inner end cover (1.1) are used to connect and fix the entire distribution mechanism simulation component, and the clutch pointer sleeve (1.5) is used to protect the pointer.

[0034] The simulation component of the distribution mechanism also includes four reset buttons to simulate fault repair, such as... Figure 4 As shown, it includes: four reset button switches (3.1) and an inspection window cover (3.2). The four buttons are: gear shift disk drive motor reset button, steering arm drive motor reset button, clutch pointer drive motor reset button, and electromagnetic clutch reset button.

[0035] The host computer issues fault requests, and the crew repairs faults by controlling the corresponding fault location drive motor through the drive box assembly. The drive box assembly is connected to the distribution mechanism simulation device via external cables. The drive box assembly... Figure 5 As shown, it includes: a drive box housing (4.1), a gear shift disk drive motor driver (4.2), a steering arm drive motor driver (4.3), a clutch pointer drive motor driver (4.4), a gear shift disk drive motor controller (4.5), a steering arm drive motor controller (4.6), a clutch pointer drive motor controller (4.7), and a data acquisition system board (4.8).

[0036] Working principle of clutch pointer drive motor: When the clutch pointer drive motor (2.11) rotates, it drives the small gear to rotate, the small gear drives the large gear to rotate, and the large gear drives the clutch scale plate (1.6) to rotate in the limit groove of the inner end cover (1.1), thereby achieving the simulation of setting faults and restoring normal state.

[0037] Working principle of the steering arm drive motor: When the steering arm drive motor (2.10) rotates, it drives the small gear to rotate, the small gear drives the large gear to rotate, and the large gear drives the limit frame assembly (1.2) to rotate in the limit groove of the inner end cover (1.1), thereby achieving the simulation of setting faults and restoring normal state.

[0038] Working principle of the gear shift disk drive motor: When the electromagnetic clutch (2.3) is energized, it locks the gear shift shaft of the gear shift shaft assembly (2.2), preventing the large and small gears in the gear meshing assembly (2.4) from rotating, thus locking the gear shift disk and preventing it from rotating. When the electromagnetic clutch (2.3) is not energized, the rotation angle of the gear shift disk can be adjusted by the gear shift disk drive motor (2.7). This achieves the simulation of setting faults and restoring normal operation.

[0039] After removing the fixing screws of the inspection window cover (3.2), the fault can be eliminated by pressing the corresponding reset button (3.1) to simulate the operation of replacing the part. Only by pressing the corresponding button can the fault be eliminated and the distribution mechanism be restored to normal.

[0040] A drive motor uses a corresponding motor driver and motor controller. For example, the clutch pointer drive motor driver and clutch pointer drive motor controller can only control the rotation angle of the clutch pointer drive motor, and cannot control the rotation of the other two motors.

[0041] This invention will provide trainees with simulations of fault phenomena that closely resemble real-world installations. The fault setting process is as follows: Figure 6 As shown.

[0042] Instructors can configure fault settings via the host computer. After setting the fault, the acquisition system board controls the drive motor or electromagnetic clutch of the distribution mechanism simulation device through the drive box assembly to generate fault phenomena. Trainees analyze the fault in the distribution mechanism simulation device, determine the fault location, and then press the corresponding reset button to generate an electrical signal, which is transmitted to the acquisition system board. The acquisition system board then transmits the signal to the host computer, which evaluates the operation. If the operation is correct, the signal is transmitted back to the acquisition system board, which controls the drive box assembly to control the drive motor or electromagnetic clutch, restoring the distribution mechanism simulation device to normal operation, and the trainee completes the fault repair. If the operation is incorrect, the distribution mechanism simulation device retains the fault phenomenon, and the trainee's operation is considered incorrect.

[0043] Fault 1: When the host computer sets the fault to be caused by "the clutch pointer sleeve on the distribution mechanism is not adjusted to the marked number "1", the acquisition system board controls the drive box assembly to drive the clutch pointer drive motor (2.11) to drive the clutch scale plate (1.6) to rotate, so that the clutch pointer sleeve (1.5) pointer points to the marked number "0".

[0044] Fault 2: When the host computer sets the fault to be caused by "the two adjusting bolts on the pointer sleeve have inconsistent adjustment range", the acquisition system board controls the drive box assembly to drive the clutch pointer drive motor (2.11) to drive the clutch scale plate to rotate, so that the pointer of the clutch pointer sleeve (1.5) cannot accurately point to the number on the clutch scale plate (1.6).

[0045] Fault 3: When the host computer sets the fault to be caused by "internal fault of the distribution mechanism", the acquisition system board controls the drive box assembly to drive the electromagnetic clutch (2.3) inside the distribution mechanism, so that the speed change shaft component (2.2) of the distribution mechanism is locked and cannot be rotated.

[0046] Fault 4: When the host computer sets the fault to be caused by "incorrect adjustment of bolt joint length on the rear longitudinal tie rod assembly", the acquisition system board controls the drive box assembly to drive the steering arm drive motor (2.10) to drive the limit frame assembly (1.2) to rotate and adjust the position of the limit frame assembly (1.2).

[0047] Fault 5: When the host computer sets the fault to be caused by "loose locking nut of bolt joint", "incorrect adjustment of the length of the final limit screw on the rear longitudinal tie rod (left and right) component" or "loose locking nut of limit screw", the acquisition system board controls the drive box assembly to drive the steering arm drive motor (2.10) to drive the limit frame assembly (1.2) to rotate and adjust the position of the limit frame assembly (1.2).

[0048] Fault 6: When the host computer sets the fault to be caused by "the pointer on the distribution mechanism does not coincide with the corresponding guideline on the scale of the distribution mechanism", "the horizontal shaft coupling of the speed change linkage is loose", or "the adjustment link of the speed change control system is loose", then the acquisition system board controls the drive box assembly to drive the gear plate drive motor (2.7) to drive the gear plate component (2.6) to rotate, and adjust the relative position of the gear plate scale line and the gear plate pointer.

[0049] After a fault is generated, the occupant determines the fault point based on the fault phenomenon. After determining the fault point, the occupant presses the reset button switch of the corresponding fault distribution mechanism simulation device. The host computer controls the gear shift disk drive motor / steering arm drive motor / clutch pointer drive motor or electromagnetic clutch to return to the initial position through the drive control box assembly. This completes the training process from setting the fault, generating the fault phenomenon, troubleshooting the fault, locating the fault point, and restoring normal operation, thereby enabling the occupant to become familiar with the faults of the distribution mechanism.

[0050] The key point of this invention is that the entire system is based on the above-mentioned structural components as a basic framework, and then embeds the corresponding electronic control system and software system to jointly construct a complete maintenance simulation system, realizing the teaching and training functions required by the user.

[0051] The data acquisition system board completes the driving and information acquisition of the distribution mechanism simulation device. Based on the fault point sent by the host computer, it controls the gear shift disk drive motor / steering arm drive motor / clutch pointer drive motor or electromagnetic clutch rotating or locking components to generate fault phenomena. After troubleshooting the distribution mechanism based on these phenomena, trainees restore its function, thus achieving fault simulation of the distribution mechanism simulation device.

[0052] The fault reproduction and troubleshooting of the distribution mechanism simulation device allows trainees to conduct repeated training, and the fault phenomena can be randomly set among the fault points.

[0053] This invention provides a distribution mechanism simulation device for a special vehicle maintenance training simulator. It integrates common distribution mechanism fault manifestations and simulates the faults, providing trainees with a more realistic and comprehensive fault simulation with higher simulation accuracy. This represents a breakthrough compared to similar equipment currently in service.

[0054] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
