Embodiment
The present invention is further described below in conjunction with accompanying drawing and instantiation.
Variable-damping shock involved in the present invention is by changing the useful area of the restriction that vibration damper fluid flows through, thereby reaches the purpose of the damping force that changes vibration damper.This kind variable-damping shock is as shown in Figure 1 on the basis of existing bitubular dydraulic shock absorber, bore 1～4 pair of circular hole that centre distance does not wait at the clutch release slave cylinder tube wall along its generatrix direction, the equilibrium position in hole is the residing equilibrium position of piston of vibration damper under the load rating of vehicle.As shown in Figures 2 and 3, the hole size that is bored on the clutch release slave cylinder is Φ 1.0～3.0mm, hole centre distance is 25～60mm, and the environment outside hole and the clutch release slave cylinder is separated, and the concrete size in the hole on its clutch release slave cylinder, hole centre distance and quantity should be decided according to the vehicle of used vibration damper.As shown in Figure 4, be designed to 1 pair or when being a kind of length more than 1 pair and pitch-row, if piston amplitude is smaller, when only moving, piston upper and lower cavity fluid can also flow when the quantity in hole between two holes except flowing by piston valve system between two holes on the clutch release slave cylinder; If piston amplitude is bigger, when it vibrates outside two holes, piston upper and lower cavity fluid can only flow by piston valve system, because effective throttle orifice that fluid flows reduces, under identical velocity of piston, damping force when the damping force when piston moves between two holes is moved outside two holes than piston is little, so this variable-damping shock can provide " soft ", " firmly " two kinds of damping forces.In like manner, as shown in Figure 5, when the quantity in hole is 2 pairs or when being 2 kinds of length more than 2 pairs and pitch-row, this variable-damping shock can provide " soft ", " in ", " firmly " three kinds of damping forces; As shown in Figure 6, when the quantity in hole be 3 pairs or when being 3 kinds of length more than 3 pairs and pitch-row, this variable-damping shock can provide 4 kinds of damping forces; As shown in Figure 7, when the quantity in hole is 4 pairs and pitch-row when being 4 kinds of length, this variable vibration damper can 5 kinds of damping forces.
