When the automobile passes through the uneven road surface, although the shock absorption spring in the shock absorption system can filter the shock of the road surface, the spring can still do reciprocating motion, and the shock absorber is used for inhibiting the spring from jumping back and forth. The shock absorber has the structure that a piston rod with a piston is inserted into a cylinder, and the cylinder is filled with oil. The piston is provided with oil guide grooves, so that the oil in the two parts of the space separated by the piston can be supplemented with each other. The working principle of the shock absorber is that when the frame and the axle or the vehicle body and the axle are vibrated to move relatively, the piston in the shock absorber moves up and down, oil in the cavity of the shock absorber repeatedly flows into the other cavity from one cavity through different pores, and at the moment, the friction between the hole wall and the oil and the internal friction between oil molecules form damping force on the vibration, so that the vibration energy of the vehicle is converted into oil heat energy, and then the oil heat energy is absorbed by the shock absorber and dissipated into the atmosphere. The guider is one of important parts in the shock absorber, plays a good role in guiding the movement of a piston rod in the shock absorber, ensures the smoothness of the piston in the operation process, and simultaneously communicates the working cylinder with the oil storage cylinder through an oil hole of the guider in the movement process of the piston.
The structural design of current annular runner and oil guide groove, the diapire process that the downthehole fluid of frizing got into annular runner need pass through one section inclined plane, and the flow efficiency of fluid is lower, and in the in-service use process, because long-time use, fluid is lower at annular runner's the efficiency of passing through, leads to director both ends oil return unbalanced, and fluid distributes inhomogeneously, and life is short.
