The working principle of automotive shock absorption involves three main stages: 1. Compression stroke stage: When the axle and frame are close to each other, the shock absorber provides a smaller damping force. In this way, the elastic element can fully exert its elastic effect, thereby mitigating impact. At this stage, elastic elements play a major role. 2. Suspension extension stroke stage: When the axle and frame are far away from each other, the shock absorber needs to provide greater damping force to quickly absorb shock. 3. Automatic adjustment stage: When the relative speed between the axle (or wheel) and the frame is too high, the shock absorber needs to have the ability to automatically increase the fluid flow. In this way, the damping force can always be maintained within a certain range, preventing the car from being subjected to excessive impact loads. In summary, the working principle of automotive shock absorbers is to lower the set resistance force in different driving states to ensure the smoothness and safety of vehicle operation. |
