The automobile damping shaft slogan is a general term in the automobile chassis industry, and the automobile damper is actually a vibration damper. The damper is used not only in suspension but also in other locations in automobiles. For example, it can be used as a bumper on a vehicle bumper for a cab, a seat, a steering wheel, and the like.

In the automotive suspension system, the barrel damper is widely used, and both the compression and the extension stroke can be used as the vibration damper, and the new type damper, which includes the inflatable damper. Adjustable damper with resistance and resistance.

Description of the working principle of the two-way action cylinder damper. In the compression stroke, the vehicle wheel is moved closer to the vehicle body, and the damper is compressed, at which time the piston 3 moves downward in the damper. The volume of the lower chamber of the piston is reduced, the oil pressure is increased, and the oil flows through the flow-through valve 8 to the chamber (upper chamber) above the piston. The upper chamber is occupied by the piston rod 1 by a portion of the space, so that the increased volume of the upper chamber is smaller than the volume of the lower chamber, and the portion of the oil then pushes the compression valve 6 back to the reservoir 5. The oil savings of these valves create a damping force for the suspension to be compressed. When the damper is in the extension stroke, the wheel is equivalent to being away from the vehicle body, and the damper is stretched. At this time, the piston of the damper moves upward. The oil pressure in the upper chamber of the piston rises, the circulation valve 8 is closed, and the oil in the upper chamber pushes the extension valve 4 into the lower chamber. Due to the existence of the piston rod, the oil flowing from the upper chamber is not enough to fill the increased volume of the lower chamber, and the main chamber causes the lower chamber to generate a vacuum degree. At this time, the oil in the storage cylinder pushes the compensation valve 7 into the lower chamber to be replenished. . Due to the throttling action of these valves, the suspension acts as a damping force during the extension movement.
