Problems solved by technology

At present, the measurement of AT clutch leakage is realized by means of gas pressurization. The defect of this measurement method is that it cannot simulate the actual operating conditions of the clutch. Therefore, a method that can dynamically measure the clutch leakage on the test bench is needed. method

Abstract

The invention relates to a clutch leakage testing device and testing method, belonging to the field of transmission testing, comprising: a fuel tank, an oil inlet pipe, a test device, a solenoid valve, a heating device and a computer. The circuit is connected to the solenoid valve, the solenoid valve is connected to the test device through the pipeline, the test device is connected to the oil tank through the pipeline, and the computer controls the on-off of the solenoid valve. In the invention, the clutch to be tested is placed on the test platform, and the leakage is measured during rotation. Accurately control the pressure, and the measurement environment is similar to the real working environment of the tested clutch. The invention realizes various working conditions of any combination of oil temperature, oil pressure and rotational speed, and can fully test the leakage amount under various working conditions by simulating the actual working condition of the clutch inside the transmission. Through the leakage measurement of the clutch by the invention, the result is true and reliable.

Description

technical field [0001] The invention relates to a clutch leakage test device and a test method, belonging to the technical field of transmission tests. Background technique [0002] At present, there is a certain degree of leakage in AT clutches on the market, and the leakage and pressure are interrelated, so the size of the leakage directly determines whether a given pressure can meet the needs of the clutch. At present, the measurement of AT clutch leakage is realized by means of gas pressurization. The defect of this measurement method is that it cannot simulate the actual operating conditions of the clutch. Therefore, a method that can dynamically measure the clutch leakage on the test bench is needed. method. Contents of the invention [0003] In view of this, the object of the present invention is to provide a clutch leakage testing device and testing method. [0004] A clutch leakage testing device, comprising: a fuel tank, an oil inlet pipe, a testing device, a s...
