Description

Technical Field

[0002] An automatic transmission (English: Auto Transmission) is a transmission device that can automatically shift gears according to the vehicle speed and engine speed, which is different from a manual transmission. There are four common types of automatic transmissions in automobiles, namely hydraulic automatic transmissions (AT), mechanical continuously variable transmissions (CVT), electronically controlled mechanical automatic transmissions (AMT) and dual-clutch automatic transmissions. Transmissions are commonly used transmission devices in mechanical transmission processes, and their main function is to change torque, speed and rotation direction. In order to ensure the quality of the transmission, it is necessary to test it during production and maintenance.

[0003] The existing automatic transmission detection device usually needs to be fixedly installed on the detection table when in use, and the traditional installation method mostly uses bolts to fix the connection. The installation process of this method is relatively cumbersome, which greatly reduces the detection efficiency. In addition, in the actual detection process of the existing automatic transmission detection device, due to the various types of transmissions, the outer diameters of the input shafts and output shafts of various types are different. During the detection process, a special connector is often required to connect the speed sensor and the motor. Therefore, the existing automatic transmission detection device has the disadvantages of being inconvenient for quick installation and fixation and poor adaptability of the connector.
