Detection device for detecting coaxiality of shock absorber
Technical Field
The utility model relates to a axiality detects technical field, specifically is a detection device for detecting bumper shock absorber axiality.
Background
The shock absorber is used for inhibiting the shock when the spring absorbs the shock and rebounds and the impact from the road surface. The damping device is widely applied to automobiles and is used for accelerating the attenuation of the vibration of a frame and an automobile body so as to improve the driving smoothness of the automobiles. When the shock absorber passes through the uneven road surface, although the shock absorbing spring can filter the shock of the road surface, the spring can still reciprocate, and the shock absorber is used for inhibiting the spring from jumping.
In order to improve the running smoothness of the automobile, a shock absorber is arranged in the suspension in parallel with the elastic element, and is used for attenuating the shock. At the moment, the friction between the hole wall and the oil and the internal friction between oil molecules form damping force on vibration, so that the vibration energy of the automobile is converted into oil heat energy, and then the oil heat energy is absorbed by the shock absorber and is emitted into the atmosphere. When the cross section and other factors of the oil passage are not changed, the damping force is increased and decreased along with the relative movement speed between the vehicle frame and the vehicle axle (or the vehicle wheel) and is related to the viscosity of the oil.
The coaxiality is a positioning tolerance, and the theoretical correct position is a reference axis. Since different points of the measured axis relative to the reference axis may appear in all directions in space, the tolerance zone is a cylinder with the reference axis as the axis, the tolerance value is the diameter of the cylinder, and the symbol "Φ" is added before the tolerance value.
