And cross bar, the sliding block of lower frame are hinged.
A pair of symmetrical long connecting rod 8 is hinged on the rear transverse rod 25 of upper frame 1, long connecting rod 8 is cut with scissors with set square 7 respectively
It connects, an angle of set square 7 and the rear transverse rod 25 of lower frame 2 are hinged, another angle of set square 7 passes through short connecting rod 26 and sliding block
27 is hinged.
Nonlinear spring group is made of main spring structure 6 and auxiliary spring structure 5, and main spring structure 6 is oppositely oriented by two
Spring be set with composition, on boss 15, boss 15 is fixed together 6 liang of end caps of main spring structure with sliding block 27, passes through one
Main shaft 16 across nonlinear spring group center is together by a threaded connection with sliding block 27.It is traversed in 6 two sides of main spring structure
Two axis 14 are fixed together with lower frame 2.Auxiliary spring structure 5 is made of leaf spring 19 and roller 17, and 17 center of roller has
Pin both ends are processed trench structure by one short pin 30, and 19 one end of leaf spring is inserted and secured in trench structure, and upper and lower two
Leaf spring 19 is hinged on one end of the first lifting lug 20, the second lifting lug 21, and the first lifting lug 20 and 21 other end of the second lifting lug are logical
It crosses short axle 28 and the first plate 22, the second plate 23 is hinged, big handwheel 12 is sleeved on main shaft 16 and small handwheel 13, is had on small handwheel 13
Position limiting structure is contacted to limit and be moved forward and backward with auxiliary spring structure 5, and small handwheel 13 is linked together by screw thread with third plate 29.
Big handwheel 12 is connect by screw thread with the first plate 22.
Working process and principle of the invention:
The working process and principle of height adjustment: as shown in Fig. 6, Fig. 7, Fig. 8 and Fig. 9, when the driver of different heights makes
Used time, eye ellipse status requirement when in order to guarantee that eyes are in driving condition, the height of seat suspension will be adjusted, and be wanted
After guaranteeing that height adjusts, the anti-vibration performance of suspension does not change.The level that the present invention passes through control nonlinear spring group entirety
It is mobile, and the deflection of nonlinear spring group constant realizes above-mentioned requirements in moving process.By rotating the big handwheel in Fig. 2
12, it is threaded due to big handwheel 12 and casing one and between lower frame 2, when rotating big handwheel 12, casing then edge
Its axis direction, that is, horizontal direction it is mobile.This has just driven entire nonlinear spring group to move horizontally, and comes from the visual angle of Fig. 3
It sees, if nonlinear spring group is integrally moved to the left,
Short connecting rod 26 pulls set square 7, and set square 7 drives long connecting rod 8, and the angle between set square 7 and long connecting rod 8 increases
Greatly, then the height of seat suspension increases, to adapt to the lesser driver of height；If nonlinear spring group integrally moves right
Dynamic, short connecting rod 26 pulls set square 7, and set square 7 drives long connecting rod 8, and the angle between set square 7 and long connecting rod 8 reduces, then seat
The height of chair suspension increases, to adapt to the higher driver of height.Nonlinear spring group is during moving horizontally, groups of springs
Deflection it is constant, therefore height adjustment on weight regulation process without influence.
The working process and principle of weight regulation: when different weight driver in use, due to weight difference, will lead to
The decrement of nonlinear spring group is different, on the one hand causes equilbrium position when suspension work to change, in addition, will lead to suspension
Anti-vibration performance reduces, and suspension of the invention is Nonlinear Suspension System, and driver's weight matches just with the Nonlinear Characteristic Curve of suspension
Therefore the low frequency vibration isolation performance being able to achieve will be adjusted to adapt to the weight of driver.If the driver of different weight
It uses, adjusts the small handwheel 13 in Fig. 2, big handwheel 12 does not rotate at this time, and small handwheel 13 drives the rotation of intermediate optical axis, optical axis
Thread connection between right end and third plate 29, and third plate 29 does not rotate and then, then third plate 29 is similar in ball-screw
Nut will be moved along the axis direction of optical axis.This will change the decrement of the main spring in nonlinear spring group, and weight is larger
Driver use, then be moved to the left third plate 29, increase the pre compressed magnitude of spring；The lesser driver of weight uses, then
So that third plate 29 is moved right, reduces the pre compressed magnitude of spring.
Realize nonlinear principle: the present invention realizes that power-displacement of horizontal direction groups of springs is special by nonlinear spring group
Property non-linear, i.e., the low dynamic rate characteristic of high static rigidity is presented, then by being made of short connecting rod 26, set square 7 and long connecting rod 8
The link mechanism vertical direction that converts entire suspension for this horizontal direction nonlinear characteristic non-linear force-displacement it is special
Property, to meet the needs of engineering truck low frequency vibration isolation performance.The nonlinear characteristic of nonlinear spring group is by will be linear
Main spring realization in parallel with the leaf spring structure of roller structure is equipped with.When sliding block 27 moves horizontally, main spring decrement
Variation, while sliding block 27 pushes roller 17 to make two spring deflections, two leaf springs play the work of rigidity correction at this time
With.The force-displacement behavior of sliding block horizontal direction is presented non-linear.This nonlinear characteristic is transformed by link mechanism again
The vertical direction of entire seat suspension, then this suspension has nonlinear characteristic in the vertical direction.
