Description

TECHNICAL FIELD

[0002] As one of the main components of the automobile power assembly, the function of the transmission affects the driving stability and the steering stability of the vehicle, so the transmission needs to be diagnosed and calibrated after production to ensure its normal function. The off-line test is the last test before the transmission is shipped, and the test needs to be carried out on a closed assembly test bench. The off-line test time of a single transmission directly affects the test efficiency of the off-line test bench. The front end of the transmission is a hydraulic torque converter, and the transmission is connected with the test bench through the hydraulic torque converter. When the test starts, the measured part needs to be docked and positioned with the test bench. After the test is completed, the measured part needs to be separated from the docked test bench, and the measured part exits the test bench.
