  Transmission tilt test system—product background


  The gearbox tilt test system is used to test the tilt state of the automobile gearbox. This system tests and verifies the inclination state of the gearbox under various road conditions. The tilting table is suitable for the automobile gearbox to operate in the tilting state of the four directions of pitch and rotation. The test bench is tilted through axial tilt and axis rotation. To achieve the transformation of the transmission attitude, the tilting movement in the four directions can be controlled independently or in combination.
