Automobile power assembly suspension damping performance detection device

The invention relates to the technical field of performance detection, and discloses an automobile power assembly suspension damping performance detection device, which comprises a rotary spacing regulation and control structure, a sliding part fixing structure and a hub caliper type part fixing structure. The automobile power assembly suspension damping performance detection device can be installed on a shaft body at the bottom of an automobile carriage and a hub of an automobile, can reflect changes of the amplitude and frequency of vibration of the automobile by checking the distance difference between the laser range finder and the ground in the driving process, can more intuitively reflect the damping performance of the automobile, and can be used for detecting the damping performance of the automobile. Besides, due to the fact that the device can enable the detection instrument to be in a vertical suspension state all the time according to the gravity of the device, and a difference value caused by auto
