Description
Technical Field
The utility model relates to the technical field of damping and shock absorption, in particular to a shock absorption and shock absorption mechanism.
Background
Damping valve arrangements for shock absorbers generally comprise a damping valve body having at least one through-opening for a damping medium and at least one valve disk which bears against the damping valve body. The valve disk at least partially covers the through-flow opening in the damping valve body under the action of the closing force. The damping valve device is flown through by a damping medium. The damping medium flows through the through-opening in the damping valve body and presses against the valve disk that rests on the damping valve body. If the damping medium pressure exceeds the closing force of the valve disc, the valve disc lifts from the damping valve body and lets the damping medium flow through the valve. In this case, the pressure equalization occurs relatively abruptly. If the damping medium pressure now drops, the valve disk, to which the closing force is applied, immediately re-closes and at least partially covers the through-opening in the damping valve body. The damping valve device has the advantages that the contact area between the valve disc and the damping valve body is small, the valve disc is easy to deform after long-term use, the fastening action of the damping valve body on the valve disc is weakened, the joint tightness of the damping valve body and the valve disc can be reduced, the damping force value is reduced, and the durability is reduced. The existing damping valve device also has the problems that when damping medium such as hydraulic oil flows through, the hydraulic oil is easy to generate bubbles, the quality of the hydraulic oil is reduced, the service life is shortened and the like. In addition, the existing damping valve device has the problems that damping is not adjustable, single damping setting cannot be suitable for changeable application occasions, and the like.
