Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle testing technology, and in particular to a testing and experimental device for an integrated power unit of a vehicle. Background Technology
[0002] Currently deployed vehicles all utilize integrated power units that combine the powertrain and transmission, employing a modular maintenance design. However, during actual maintenance, if any component within the module, such as the clutch, gearbox, generator, or starter, malfunctions, the integrated power unit must be hoisted and installed. After maintenance, if the operating parameters of a component do not meet technical requirements or the malfunction persists, the above steps must be repeated until all component operating parameters meet the standards. Each time the power compartment is hoisted out and installed, it takes approximately 100 minutes.
[0003] Most testing platforms are bulky and immobile. Local repair shops rely on vehicle-mounted systems and can only conduct tests inside the vehicle. Repeated disassembly causes damage to parts (high-strength bolts, quick connectors, aviation plugs, etc. have a limited number of uses), affecting the service life of parts. In addition, the time spent is too long, reducing repair efficiency. Multiple hoisting operations can easily increase safety hazards.
[0004] Therefore, to address the above issues, an external, mobile testing and inspection device for integrated vehicle power units is proposed, which reduces repetitive hoisting procedures for integrated power units, lowers safety risks, and improves maintenance efficiency. Utility Model Content

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0027] Example 1: As Figures 1 to 4 As shown, this application provides a testing and inspection device for an integrated vehicle power unit, including a test bench. The test bench consists of a chassis 1, a seat 2, and an equipment box 3. A seat 4 is fixedly connected to the seat 2, and multiple casters 5 are fixedly connected to the chassis 1. Two of the casters 5 are equipped with braking mechanisms to secure the test bench in its operating position and prevent displacement during use. Both the equipment box 3 and the seat 2 are hinged with doors 25.
[0028] The equipment box 3 contains an engine detection device 6, which includes a first oil pressure sensor 7, a water temperature sensor 8, a speed sensor 9, an exhaust temperature sensor 10, an intake pressure sensor 11, and a foot pedal 12.
[0029] The first oil pressure sensor 7, water temperature sensor 8, speed sensor 9, exhaust temperature sensor 10, and intake pressure sensor 11 are all electrically connected to the controller 13. The foot pedal 12 is installed on the side wall of the equipment box 3 for easy access by personnel. In use, the engine detection device 6 can employ electronic control and adjustment technology to automatically monitor and diagnose the engine of the vehicle by comparing oil pressure and water temperature and observing the sealing of external pipelines, thereby determining whether the engine has any faults.
[0030] The equipment box 3 is also equipped with a clutch detection device 14, which includes a clutch assembly 15, a connecting pipeline 16, and a second oil pressure sensor 17.
[0031] During test drives, the clutch can be disengaged or engaged by depressing the clutch assembly 15, allowing for checks on its operational status. During this process, the travel of the clutch assembly 15 is observed, and the transmission oil pressure is monitored using the second oil pressure sensor 17. This allows for checks on the clutch's disengagement and engagement, and helps determine if any clutch malfunctions are present.
[0032] The equipment box 3 is equipped with a gearbox testing device 18, which is connected to an air pipe 19, a shifting device 20, and a gear shifting control mechanism.
[0033] A shifting device 20 is installed on the test bench. The switching of each gear of the transmission is controlled by the air pipe 19 and the gear shifting mechanism. The working condition of the transmission can be detected, and it is convenient to check whether there are problems such as gear grinding and disengagement when shifting gears. At the same time, it can be observed whether there is oil leakage in the pipeline, so as to determine whether there is a fault in the transmission.
[0034] The power detection box 21 is installed inside the seat 2. The power detection box 21 is equipped with a power generation control box 22 and a current transformer 23.
[0035] In vehicles, a generator is typically used as the primary power source, supplying power to electrical devices via the main distribution box and thermal protection switch box. By connecting the generator in parallel with a battery, the power system of the armored vehicle is formed. In this embodiment, the generator control box 22 and current transformer 23 are modified and installed in a test bench via optimized wiring, forming a DC generator that integrates power generation, voltage stabilization, overcurrent protection, and overvoltage protection. During use, it automatically adjusts the generator's excitation current to maintain the generator's output terminal voltage within a specified range.
[0036] The equipment box 3 has multiple heat dissipation holes on its side wall and a dustproof net 24 is installed on the equipment box 3. The dustproof net 24 is located outside the heat dissipation holes and can dissipate heat from the equipment inside to maintain its operating condition.
[0037] In actual use, the testing equipment for integrated vehicle powertrain according to the embodiments of this application is as follows:
[0038] The vehicle to be tested can be electrically and piped to the test bench. During operation, the engine operating parameters can be collected in real time through the first oil pressure sensor 7, water temperature sensor 8, speed sensor 9, exhaust temperature sensor 10 and intake pressure sensor 11 in the engine testing device 6, and the signals are transmitted to the controller 13. The operator can simulate throttle control through the foot pedal 12 to realize comprehensive monitoring and fault diagnosis of the engine.
[0039] Through the clutch assembly 15 and connecting pipe 16 in the clutch detection device 14, the operator can step on the clutch pedal to simulate the clutch disengagement and engagement process. The second oil pressure sensor 17 can monitor the changes in transmission oil pressure. Combined with the observation of the push rod stroke, it can be determined whether the clutch is working normally and whether there are faults such as incomplete disengagement or poor engagement.
[0040] Through the air pipe 19 and shifting device 20 in the transmission detection device 18, the operator can perform gear switching operations to check whether the shifting is smooth, whether there is any grinding or disengagement, and at the same time observe the sealing of the pipeline to determine whether there is any oil leakage or abnormal operation of the transmission. The generator control box 22 and current transformer 23 in the power detection box 21 can simulate the working state of the vehicle power system, realize the automatic adjustment of the generator output voltage and current and the overvoltage and overcurrent protection functions, and ensure that the generator operates within a safe range.
[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
