The utility model to achieve the goals above, adopts the following technical scheme that：A kind of damping of dual spring forward-reverse spiral
Device device, be by：First outer spring, the second outer spring, the first outer support circle, the second outer support circle, shank, shell are constituted；Subtract
Shake device is made of shank and shell, and one end of shank is fixed by the way that hex bolts is correspondings with dustband, the other end of shank and outside
One end of shell corresponds to fitting, and by being sealed between dustband and shank, shell is arranged between two cylinders for one end of shell
Round estrade is constituted, and the diameter of shell one end is more than the diameter of the other end, and bulge loop is arranged in one end outer wall of shell, close to the one of shank
The periphery at end is respectively set the first outer support circle and the second outer support circle, outside the second outer support circle inner face and the first outer support circle
End face corresponds to fitting, and the first outer support circle and the second outer support circle are that cross section is inverted U-shaped loop configuration, and is propped up outside first
Support ring and the second outer support circle are concentric circles, and the diameter of the second outer support circle is more than the diameter of the first outer support circle, is propped up outside first
The second outer spring is formed between the outer wall of support ring and the outer wall of the second outer support circle places cavity, the inner face of the first outer support circle
First outer spring is set between one end end face of shell, and the first outer spring is located at shank periphery, the inner end of the second outer support circle
Second outer spring is set between face and the end face of shell bulge loop, and one end of the second outer spring is located at the second outer spring and places cavity
Interior, the other end of the second outer spring is located at shell one end periphery, and the diameter of the first outer spring is less than the diameter of the second outer spring.
First outer spring is located at the inside of the second outer spring, the axial line weight of the first outer spring and the second outer spring
It closes.
The winding direction of first outer spring is that counterclockwise, the winding direction of the second outer spring is square clockwise
To.
First outer spring is equal pitch spring, and the second outer spring is variable-pitch spring.
The utility model has the beneficial effects that：The utility model installs the first outer spring and the second outer bullet additional on damper
Spring, the first outer spring it is left-handed be equal pitch spring, the second outer spring dextrorotation be variable-pitch spring, the right complementation of two springs, one the first from left,
The effective spring that avoids intersects deformation, increases the whole lifting capacity of damper, and entire damper is made of multiple springs,
It can be combined into the spring force value curve of a variety of different-stiffness, can be combined under different transport conditions according to different vehicles
The support force value to match, this reality utility model is simple in sturcture, ingenious in design, and low production cost is easy to operate, using effect
Significantly, durable, long-time service is hardly damaged, and is suitble to popularity application.
