Description

Technical Field

[0001] This invention relates to the field of testing system technology, and in particular to an electronically controlled clutch testing system and method. Background Technology

[0002] Electronically controlled clutches are one of the core components of automotive powertrain systems. Compared to traditional mechanical clutches, they achieve automated and precise control of clutch engagement and disengagement through the coordinated work of electronic control units (ECUs), actuators (such as motors and hydraulic cylinders), and sensors. They are widely used in the power coupling systems of dual-clutch transmissions (DCTs), automatic manual transmissions (AMTs), and hybrid vehicles.

[0003] As the automotive industry moves towards intelligent and electric vehicles, the market is placing stringent demands on the response speed, control precision, durability, and reliability of electronically controlled clutches. The performance of an electronically controlled clutch directly affects the smoothness of gear shifting, fuel economy, and driving safety. Therefore, during product development, production, and quality testing, it is essential to comprehensively verify all performance indicators using a professional testing system.

[0004] Testing of electronically controlled clutches often relies on real-vehicle road tests. While real-vehicle road tests can reflect the actual working performance of the clutch, they are time-consuming, costly, and difficult to achieve controllable testing of the clutch's limit performance and durability. They also pose certain safety risks. Summary of the Invention

[0005] The purpose of this invention is to provide an electronically controlled clutch testing system and method, which aims to solve the problems of long testing cycles, high costs, and difficulty in controlling the testing of traditional electronically controlled clutches.

[0006] To achieve the above objectives, in a first aspect, the present invention provides an electronically controlled clutch testing system, comprising a test bench, a control panel, a clutch detection fixture, an electronic pump fixture, a solenoid valve fixture, and a gas source; the control panel is mounted on one side of the test bench, the electronic pump fixture is disposed on one side of the test bench, the solenoid valve fixture is disposed on both sides of the electronic pump fixture, and the clutch detection fixture is disposed on the side of the solenoid valve fixture away from the electronic pump fixture.

[0007] The test bench includes a frame and casters. The frame is fixedly connected to the control panel and is located on one side of the control panel. The casters are mounted on the bottom of the frame.

[0008] The test bench also includes a brake lever, which is mounted on the side of the frame near the caster wheel.

[0009] The clutch detection fixture includes a clutch actuator and a first fixture, the first fixture being assembled on one side of the frame, and the clutch actuator being disposed on one side of the first fixture.

[0010] The electronic pump fixture includes an electronic pump assembly and a second fixture. The second fixture is mounted on one side of the frame, and the electronic pump assembly is disposed on one side of the second fixture.

[0011] The solenoid valve fixture includes a solenoid valve assembly and a third fixture. The third fixture is mounted on one side of the frame, and the solenoid valve assembly is disposed on one side of the third fixture.

[0012] Secondly, the present invention also provides an electronically controlled clutch testing method, applied to the electronically controlled clutch testing system as described in the first aspect above, comprising the following steps: The electronically controlled clutch to be tested is assembled on the clutch testing fixture, and the electronically controlled clutch is connected to the air pressure sensor, displacement sensor and weighing sensor; The electronic pump fixture simulates the pedal action via the control panel. The control panel receives the signal and controls the solenoid valve fixture to supply air to the clutch detection fixture. The clutch testing fixture outputs thrust to control clutch disengagement / engagement. The air pressure sensor, displacement sensor, and weighing sensor on the test bench detect displacement parameters, output force, and sealing performance throughout the process.

[0013] This invention discloses an electronically controlled clutch testing system. The test bench provides support and a mounting foundation for other mechanisms and is equipped with a pressure sensor, a displacement sensor, and a load cell. In use, the electronically controlled clutch is connected to these sensors. The control panel controls the electronic pump fixture to simulate pedal operation. Upon receiving a signal, the control panel controls the solenoid valve fixture to open the air source, supplying air to the clutch detection fixture. This outputs thrust and displacement to control clutch disengagement / engagement. Simultaneously, the pressure sensor, displacement sensor, and load cell on the test bench detect the displacement parameters, output force, and sealing performance throughout the process. This eliminates the need for on-vehicle road testing, enabling mass production of the electronically controlled clutch system. It lays the foundation for the electronic control of clutch systems in the heavy-duty truck industry, thus solving the problems of long testing cycles, high costs, and difficulty in controlling the testing of traditional electronically controlled clutches.
