[0002] The purpose of the gearbox is to change the transmission ratio and expand the range of variation of the drive wheel torque and speed. The gearbox is a key component in the car. Once a problem occurs, it will greatly affect the use of the car. Therefore, the gearbox needs to pass testing before leaving the factory to ensure that it is qualified before it can be used.

[0003] At present, the invention patent with patent number CN202110445475.1 discloses a gearbox test bench, including a base, on which an engine, a torque tester, a gearbox unit, and a flywheel are installed in sequence, and a lifting device is installed on the base, and the lifting device is located on one side of the gearbox unit; the gearbox unit includes a gearbox base with adjustable height and horizontal position, and the gearbox base is fixedly connected to the base. The gearbox base is installed on the gearbox base, which adjusts the height and horizontal position of the gearbox base to keep the horizontal position of the gearbox consistent with that of the torque tester and the flywheel. However, the equipment bench cannot adjust and rotate the position of the gearbox front and back. When the gearbox is tilted or staggered with the test equipment front and back, the position of the gearbox needs to be manually adjusted.
