Description

Technical Field

[0001] This utility model relates to the technical field of gearbox testing equipment, specifically to an electronic control console for gearbox testing. Background Technology

[0002] As the core component for power transmission in a machine, the transmission's reliability, lifespan, and efficiency have a decisive impact on the overall performance, reliability, and efficiency of the machine. Furthermore, the transmission is a priority assembly component during the overall assembly process, and its location within the machine's space is limited. Repairing it requires disassembling numerous other parts, resulting in significant rework time and costs.

[0003] If problems are discovered outside the factory, the equipment typically needs to be transported in-house for disassembly and repair, further increasing repair time and costs, and severely impacting brand image. Therefore, better early detection and handling of transmission problems, preventing defective products from progressing to the next stage, and improving transmission reliability significantly impacts production efficiency, transmission and overall machine maintenance costs, overall machine reliability, and brand image.

[0004] Tractor gearboxes, especially power shift hydraulic differential gearboxes, have complex structures, including not only mechanical transmission parts but also hydraulic transmission and electrical control parts. Therefore, tractor gearbox testing platforms need to verify the reliability of their mechanical transmission parts and monitor their internal hydraulic and control status to ensure their functional and quality reliability.

[0005] Some commonly used gearbox testing equipment is equipped with an electronic control console, while others are not. Testing equipment without an electronic control console will use a communication cable to connect to a computer to process data. However, the existing electronic control consoles are simply used to control the operation of the testing equipment and display test data, without other functions. The overall functionality is relatively simple and cannot meet the needs of multi-performance testing equipment that integrates multiple tests. Utility Model Content

[0006] This invention provides an electronic control console for gearbox testing, which has conventional control and display functions, and can also test the steering performance of the gearbox and monitor the status of the gearbox. It can also collect test data and determine whether the performance status of the gearbox is qualified.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An electronic control console for gearbox testing includes an electronic control console frame, a steering test mechanism, a gearbox monitoring component, a data processing terminal, a data acquisition unit, a connector, and a power converter. The steering test mechanism is mounted on one end of the electronic control console frame and is used to test the steering performance of the gearbox.

[0021] Please see Figures 1 to 3 As shown, an electronic control console for gearbox testing includes an electronic control console frame 1, a steering test mechanism 2, a gearbox monitoring component 3, a data processing terminal 4, a data acquisition unit 5, a connector 6, and a power converter 7. The steering test mechanism 2 is mounted on one end of the electronic control console frame 1 and is used to test the steering performance of the gearbox. The gearbox monitoring component 3 is installed on the gearbox and connected to the connector 6 via wiring to monitor the hydraulic pressure and oil temperature inside the gearbox.

[0022] The data processing terminal 4 is located at the other end of the electronic control bench 1 and is used to control the gearbox and process and judge the test data information of the gearbox. The data acquisition unit 5 is located at the top of the electronic control bench 1 and is used to receive the test data information of the gearbox and transmit the data to the data processing terminal 4 through the line. The connector 6 is located on the inner side of the electronic control bench 1 and is connected to the steering test mechanism 2, the gearbox monitoring component 3 and the gearbox through the line. The power converter 7 is located on the inner side of the electronic control bench 1 and above the connector 6, and is used to connect the power supply and provide the electronic control bench with the starting power.

[0023] The steering test mechanism 2 includes a support frame 21, a steering wheel 22, a rotating shaft 23, and an angle sensor 24. The support frame 21 is located inside the electronic control table 1. One end of the rotating shaft 23 is mounted on the support frame 21, and the other end extends upward out of the outer surface of the electronic control table 1. The steering wheel 22 is mounted on the extended end of the rotating shaft 23. The angle sensor 24 is mounted on the end of the rotating shaft 23 near the support frame 21 and is used to transmit the angle information of the steering wheel 22 to the data processing terminal 4 via the data acquisition unit 5.

[0024] The gearbox body contains a clutch, and an external proportional valve is installed. Different current signals passing through the proportional valve affect its opening, thereby adjusting the hydraulic pressure at the clutch and ultimately controlling its operating state. During steering testing, the proportional valve is first connected via a circuit. Then, the steering wheel 22 is rotated, driving the angle sensor 24 to confirm the steering wheel 22's rotation angle. The data processing terminal 4, based on the steering wheel 22's rotation angle, controls the current passing through the proportional valve using PWM, thereby controlling the hydraulic pressure at the clutch, and consequently controlling the gearbox output shaft speed and steering. An auxiliary current detector can also be used on the circuit to detect the actual current passing through the proportional valve. The pressure sensor 31 of the gearbox monitoring component 3 is connected to the clutch to detect the working hydraulic pressure at the clutch engagement point. Finally, by determining the actual current of the proportional valve, the output shaft speed, and the hydraulic pressure at the clutch, the system determines whether the clutch's steering operation is normal.

[0025] The transmission monitoring component 3 includes a pressure sensor 31 and a temperature sensor 32 for mounting on the transmission. The pressure sensor 31 is used to transmit the hydraulic pressure data of the transmission to the data processing terminal 4 via the data acquisition unit 5, and the temperature sensor 32 is used to transmit the hydraulic oil temperature data of the transmission to the data processing terminal 4 via the data acquisition unit 5.

[0026] The control panel 1 is also equipped with a display screen 8 and control buttons 9. Both the display screen 8 and control buttons 9 are located on the upper surface of the control panel 1. The display screen 8 is used to display information from the data processing terminal, and the control buttons 9 are used as the power switch for the control panel and the operation switch for the gearbox testing device.

[0027] In use, this utility model is interconnected and used in conjunction with a gearbox and a gearbox testing device via wiring. The gearbox testing device can drive the gearbox to operate and test the output shaft speed of the gearbox, etc. The gearbox testing device can be any existing publicly available equipment. In addition to conventional control and display functions, the electronic control console can also test the steering performance of the gearbox through the steering test mechanism and monitor the status of the gearbox through the gearbox monitoring component. It can also collect test data and determine whether the performance status of the gearbox is qualified.
