Description

A kind of automobile shock absorber with buffer mechanism

technical field

The utility model relates to an automobile shock absorber with a buffer mechanism, which belongs to the technical field of automobile shock absorbers.

Background technique

The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jumping. Shock absorber is too soft, automobile body can hop up and down, shock absorber can bring too great resistance too forcedly, cloggy bedspring works normally. In the process of refitting the suspension system, hard shock absorbers should be matched with hard springs, and the hardness of the springs is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers. The device connected with the crankshaft that causes the vibration is used to counteract the torsional vibration of the crankshaft (that is, the phenomenon that the crankshaft is twisted by the impact force of the cylinder ignition). In the suspension system, due to the shock of the elastic element, the shock absorber is installed in parallel with the elastic element in order to improve the ride comfort of the car. In order to attenuate the vibration, the shock absorber used in the automobile suspension system is mostly hydraulic The working principle of the shock absorber is that when the frame (or body) and the axle vibrate and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly passes through different pores from one cavity into another cavity. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the car is converted into heat energy of the oil, which is then absorbed by the shock absorber and released into the atmosphere. When the oil passage section and other factors are constant, the damping force increases or decreases with the relative movement speed between the frame and the axle (or wheel), and is related to the viscosity of the oil.

In order to improve the driving stability of the car, a shock absorber is usually installed in the car suspension. Most of the shock absorbers currently on the market are hydraulic shock absorbers. At this time, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity through different gaps into another cavity. At this time, the friction between the hole wall and the oil and the friction between the oil molecules The internal friction forms a damping force on the vibration, so that the vibration energy of the car is converted into the heat energy of the oil, which is absorbed and dissipated into the air by the shock absorber. Although this hydraulic shock absorber has better damping effect to a certain extent, it does not have a buffering effect, and the impact force will greatly affect the service life of the shock absorber, thereby affecting the shock absorption and shock isolation effects. For this reason, it is necessary to design a new technical solution that can comprehensively overcome the deficiencies in the above-mentioned prior art.
