[0002] A transmission is a mechanism used to change the speed and torque from the engine. It can fix or shift gears to change the transmission ratio between the output shaft and the input shaft, and is also called a gearbox. The transmission consists of a transmission mechanism and a control mechanism. Some automobiles also have a power take-off mechanism. Most of the transmission mechanisms use ordinary gear transmissions, and some use planetary gear transmissions. The ordinary gear transmission mechanism generally uses sliding gears and synchronizers, etc.
[0003] After the traditional transmission simulation bench clamps the transmission, the transmission and gear shifting performance of the transmission can be detected, but it is more inconvenient to detect the NVH and other performances of the transmission; for this reason, we provide a clamping tool for simulating an automotive transmission test bench. After fixing the transmission, it is also convenient for the transmission to detect its NVH, and the detection performance is more practical, effectively making up for the above problems.
