How to Harmonize the Elasticity of Ball Valve Shock Absorber in Automobile
It is known that the ball valve shock absorber plays an important role in the automobile, and this role will not cause too smooth and easy damage in the driving of the automobile. However, the elasticity of the ball valve shock absorber is a key issue. If the elasticity is not well adjusted, it may directly cause the vibration or spring damage of the automobile components.
The greater the damping force of the ball valve damper, the faster the vibration will be eliminated. However, if the damping force is too large, the role of the elastic elements will not be fully exerted, and even the excessive damping force may cause damage to some connecting parts and the frame.
In order to harmonize the elastic element and the shock absorber, the following requests are made for the shock absorber:
1. During the suspension tightening stroke (the stroke when the axle and frame move close to each other), the damping force of the shock absorber should be small, so that the elasticity of the elastic elements can be fully applied to mitigate the impact;
2. In the suspension stretching stroke (the stroke that the axle is relatively far away from the frame), the assembling force of the shock absorber should be large, so as to reduce the vibration quickly;
3. When the relative speed between the axle (or wheel) and the frame is too high, the shock absorber should be able to automatically increase the cross-sectional area of the fluid flow channel, so that the damping force is always within a certain limit, so as to avoid being subjected to excessive impact loads.
At present, two-way acting cylinder shock absorbers are widely used in automobiles. The shock absorbers that can reduce vibration in both the tightening and stretching strokes are called two-way acting shock absorbers. Another kind of shock absorber only works during the stretching stroke. It is called one-way shock absorber.
In fact, many times the car runs on a too smooth road. When turning, the ball valve damper is constantly maintaining the car, making the car tilt to a certain extent, but not roll over. This is the ball valve damper working.
