Embodiment 1

[0051] test a clutch

[0052] S1: In the state of parts, the transmission case near the A clutch is drilled to form an outer hole; the outer hub of the A clutch is drilled to form an oil hole.

[0053] S2: After the transmission is assembled, fix the temperature sensor on the transmission housing with screws to ensure that the temperature sensor can be aligned with the oil hole on the outer hub of the clutch after passing through the outer hole.

[0054] S3: Install the transmission on the transmission loading test bench.

[0055]S4: Start the experiment; control the outer hub of clutch A to fix, test the temperature difference of the clutch friction plate under different slip and torque, and record the data, as shown in Table 1.

[0056] Table 1

[0057]

[0058] S5: According to the test data in Table 1, use processing software such as EXCEL or MINTAB to fit the relationship between the clutch temperature difference and slip and torque, such as figure 1 Shown; At the s...

Abstract

The invention relates to a method for testing the temperature of a clutch friction plate in a complete machine state of a transmission. The method comprises the following steps: in a part state, punching an outer hole in a transmission shell corresponding to a to-be-tested clutch, and punching an oil hole in an outer hub of the to-be-tested clutch; after the transmission is assembled, enabling the temperature sensor to penetrate through the outer hole and the oil hole and then extend into the outer hub of the clutch to be tested so as to fix the temperature sensor, and installing a transmission on the transmission loading test bench; starting the test, and controlling the outer hub of the to-be-tested clutch to be fixed and the inner hub to operate according to a set rotating speed. The measuring method is low in cost, and only the temperature sensor needs to be fixed by punching on the transmission shell and the temperature sensor is inserted into the clutch outer hub by punching. Through the test method, the temperature of the clutch under different rotating speed differences can be measured. The temperature has great reference significance in control of sliding friction of the clutch in software, and the conditions such as burning loss of the clutch caused by unreasonable parameter setting are avoided.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a method for testing the temperature of clutch friction plates in the complete state of the transmission. Background technique [0002] Among the failure modes of the whole vehicle, the judgment conditions of the failure modes such as slippage failure and runaway failure are all related to the slip of the clutch. In the design and development of the transmission, it is necessary to understand the state of the friction plates in the clutch under different working conditions (different slips, different torques). At the same time, combined with the experimental results, it is confirmed whether the judgment conditions of the software failure mode are reasonable: whether the judgment conditions are too strict, that is, the fault is falsely reported when the clutch will not be damaged; or the judgment conditions are too loose, that is, when the clutch friction plate has When the...
