During the use process, the size specifications of the main push rod, the branch push rod, the push disc, the metal rubber component and the damping spring are selected according to the tonnage of the vehicle and the intensity of impact vibration; when the suspension shock absorber is installed, a certain pretightening force is given to the reset spring to ensure that a certain distance is left between the upper edge of the sleeve and the loop bar base, the suspension shock absorber support is fixed on a frame, and the suspension shock absorber can move downwards for a small distance due to the influence of self gravity; when impacted by a road surface, the resulting vibrations will vibrate along the trilateral component of the suspension damper. In the running process, when a vehicle passes through an uneven road surface, the vehicle is subjected to impact vibration in the horizontal direction and the vertical direction; when accelerating suddenly or braking emergently, the vehicle is mainly subjected to vibration in the horizontal direction.
