Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is one embodiment of the utility model, and in Fig. 1, the top of vibration damping casing 3 is close via two casing O circles 7
Encapsulation fits in main damping lumen 19, vibration damping casing 3 and the inherently existing damper product of vibration damping plunger 2, only not
Crossing is that the outer wall of vibration damping casing 3 is thickeied and polished, and processes twice casing O ring slot 6, is further processed into main damper tube
The plunger of chamber 19；There are two each one of left and right for the secondary damping lumen 9 parallel with main damping lumen 19, as shown in Fig. 2, each leisure
Internal upper part assembly is equipped with spring 8 with the secondary damping plunger 11 of damping O circle 12, lower part；Main damping lumen 19 and two secondary dampings
Lumen 9 is connected on top through air flue 16, and the top of main damping lumen 19 and two secondary damping lumens 9 is by with end cap screw thread 13
End cap 17 is through 14 sealing of end cap O circle；The middle part of end cap 17 is equipped with pressure regulator valve connector 20, as shown in Figure 1.Main damping lumen 19 with
The top end of two secondary damping lumens 9 is arranged in parallel on a common damping cavity pedestal 18, as shown in Figure 3.End cap O circle
14 are mounted in the end cap O ring slot 22 of 18 upper surface of damping cavity pedestal.
In the sealed connection of dynamic cooperation between vibration damping casing 3 and main damping lumen 19；Two casing O circles 7 are assemblied in shock-reducing sleeve
In the casing O ring slot 6 of 3 outer ring surface of pipe, the seal chamber that there is air in one end, i.e., main damping lumen 19 are formed.Pressure regulator valve connector
20 install a pressure regulator valve (existing product) by pressure regulator valve screw thread 21, can be hindered by it to main damping lumen 19 and two are secondary
Air conditioning pressure is filled with or discharged in Buddhist nun's lumen 9, is reached and is adjusted car body and the utility model mated condition.By on end cap 17
Multiple bolts hole 15 and connector, engaging lug 1 car body and double leval jib axis connection are got up.
Working principle is: the utility model is exactly the independent suspension structure and a combined vibration-damping set of a car body
Body, when the compression of vibration damping casing 3 increases, while vibration damping plunger 2 bounces back, main damping lumen 19 and two secondary damping lumens 9 are simultaneously
It is compressed；Secondary damping plunger 11 in two secondary damping lumens 9 is moved down by compression simultaneously, and spring 8 is also compressed.Pressure becomes smaller
When, they tend to set back again.When finding effectiveness in vibration suppression decline, it can be inflated and be adjusted or replaced by the pressure regulator valve of installation
Certain O circle of abrasion, realizing improves effectiveness in vibration suppression.
