Abstract: A transmission shaft automatic connection and disengagement device and test equipment. An input shaft drives a transmission shaft to rotate through a second connection shaft, a ratchet assembly, a first connection shaft and an output shaft so as to apply an acceleration torque, gears of the input shaft and the first connection shaft can be completely engaged and completely separated through extension and retraction of piston rods of a first group of air cylinders and a second group of air cylinders so as to achieve an effect that when a driving shaft needs to perform driving, a power system gets involved, and after driving is completed, the power system is cut off, and through the ratchet assembly, the transmission shaft can be prevented from driving a motor to work in reverse.

Abstract: The present disclosure belongs to the technical field of automobile chassis suspension system tests, and provides a wheel acceleration torque system and test equipment for an automobile chassis simulation road test. The automatic connection and separation mechanism is connected with a transmission shaft of a wheel; the automatic connection and separation mechanism can apply acceleration torque of the torque shaft to the transmission shaft, and can separate the acceleration torque applied to the transmission shaft; and the wheel acceleration torque system and the test equipment can adapt to the requirement for applying the acceleration torque in a test of a test bench, simulate to apply the acceleration torque which the wheel bears in the actual road running process, ensure that a test state of a tested wheel and suspension system is close to a test state of a real automobile test field.
