Problems solved by technology

[0002] In the process of new product development and design improvement of automatic transmissions, bench tests are particularly important. Tests can verify and discover problems, and can provide important references for product design. In the past, bench tests were mainly used for complete machines, because The test can accurately reflect the real working state of the transmission, but with the advancement and innovation of technology, the importance of component testing has become more prominent. Brake bands are one of the important components of automatic transmissions. In the past, friction was mainly obtained through machine tests. Performance data such as coefficients and braking time are subject to many interference factors, such as the influence of tolerances between various parts and inaccurate control conditions, etc., which is unfavorable for the study of the performance of a single brake band. The obtained brake band performance data results are often not reliable and not stable enough

specific Embodiment approach 1

[0020] combine figure 1 , 2 , 3 and 4, the present embodiment discloses a brake band experimental device for an automatic transmission, comprising a brake band 3, a clutch 4 and a brake pressure supply oil circuit 16, the brake band 3 is sleeved on the outside of the clutch 4, The clutch 4 is arranged inside the base 12, the right end of the clutch 4 is connected with the turntable 2, the middle part of the turntable 2 is provided with a cylindrical shaft body, the shaft body is provided with a shaft oil hole, the clutch 4 is sleeved on the shaft body, the turntable 2 and the positioning Disc 1 is connected, the right end of positioning disc 1 is connected with the rotating shaft on the stand, and the rotation of the drive shaft on the stand drives positioning disc 1 to rotate, positioning disc 1 drives turntable 2, turntable 2 drives clutch 4 to rotate, and the barrel of turntable 2 A fixed sleeve 6 is arranged in the body of the shaft, and a lubricating oil through hole is ...

specific Embodiment approach 2

[0033] This embodiment is based on the specific implementation mode 1, combining image 3 As shown, further, the end of the fixed sleeve 6 has a stepped outer edge, and a washer 5 is arranged between the stepped outer edge and the clutch 4 .

[0034]The clutch is sealed by the gasket 5, and the axial movement of the clutch is prevented at the same time, the stability of the clutch operation is improved, and the problem of the reduction of the contact area with the brake band caused by the movement of the clutch during the experiment of the brake band experimental device is solved.

specific Embodiment approach 3

[0035] This embodiment is based on the specific implementation mode 1, combining image 3 As shown, further, the fixed sleeve 6 is also provided with a fixed shaft, which passes through the turntable 2 and is inserted into the positioning hole on the positioning plate 1, and the fixed shaft and the positioning hole adopt an interference fit.

[0036] The fixed shaft ensures that the fixed sleeve 6 is coaxial with the positioning disc 1, thereby ensuring that the clutch 4 and the brake band 3 remain coaxial, and solves the problem that the clutch 4 and the brake band 3 are not coaxial and affect the experiment.
