Description
Technical field
The present invention relates to shock-absorption device field, particularly relate to a kind of amortisseur and damping balance system.
Background technology
On all kinds of vehicles such as automobile, it is equipped with amortisseur, its object is to concussion when rebounding after suppressing shock-absorbing spring shock-absorbing and the impact from road surface.Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, but spring self also has reciprocating motion, and amortisseur is just used to suppress this spring to jump, making wheel quickly settle out maintenance has one to stablize lasting adhesive force with ground.
From operation principle, piston lever of reducer simply holds the spring compressed, and upsprings under certain speed.When vehicle translational to protruding road surface, impact force action is on harder spring, and its length of compression is when being not equal to ground level (height=bump height that spring-compressed length+car body rises here does not include the height that rapid translation is thrown), vibrations just produce, and now amortisseur is not also started working.So, amortisseur says it should is antivibrator accurately, and not having obvious damping effect has been Stabilization.
Current vehicle all adopts hydraulic damper mostly, when its operation principle is to shake when between vehicle frame (or vehicle body) and vehicle bridge and relative motion occur, piston in amortisseur moves up and down, and the fluid in snubber cavity just flows into another intracavity from a chamber through different holes repeatedly.Vibrations are formed damping force by now friction between hole wall and fluid and the intermolecular internal friction of fluid, make thump energy be converted into fluid heat energy, then are dispersed in air by absorber.But current amortisseur technology there is problems of damping force and do not couple with spring, damping force and spring damping force come in and go out very big, are not overdamp occur, it is simply that underdamping, apart from optimal critical damping target farther out.(when resistance makes vibrating object can not just make periodic vibration and can full out return to the situation of equilbrium position, for critical damping；Directly arrive equilibrium point friction, and the time of advent is longer for overdamp；Vibration is also had for underdamping or undamped) after arriving equilibrium point
What the most emerging magnetorheological cushion technique electromagnetic shock absorber majority showed at present is all the relation close fit more making damping force with spring, makes vehicle more smooth out relevant, but cost is abnormal high, and general car does not have such configuration.And, if the amortisseur that performance is superior more still increases damping effect on the basis of former spring, even if spring extension damping force couples discrepancy with antivibrator damping force and reaches critical damping, also can only be to ensure that the due elastic effect of spring does not interfere with spring works, increase the regularity and stability of vehicle, but can not fundamentally reduce the vibrations of vehicle.
To sum up, to further avoid vehicle vibration, it is necessary to be spring-compressed length equal or close to the height on protruding road surface, then can keep that car body is substantially parallel with road surface can be shaken by freeing vehicle.It is clearly vehicle and must adopt the spring of ultra-soft, there is super large compression travel and just have desirable effect.But, soft spring stability is excessively poor, and the left and right damping of car is just as the left and right of balance, and when running into powerful bend centrifugal force, brake weight or anxious acceleration, vehicle's center of gravity is difficult to ensure that.So in order to ensure safety, current car enterprise mostly adopts very hard spring preferentially to ensure ride safety of automobile coefficient, reduces the comfortableness taken, and the impact of road pavement is relatively big, adds the maintenance cost of highway, and can reduce the property passed through simultaneously.

Rotating cylinder drive system 400 includes the first motor the 401, second motor the 402, first rotating shaft the 403, second rotating shaft the 404, first runner 405 and the second runner 406.The sidewall of upper rotating cylinder 310 and lower rotating cylinder 320 is respectively provided with one section of tooth bar, engages with the first runner 405 or the second runner 406.First motor 401 drives the first runner 405 to rotate by the first rotating shaft 403, thus driving upper rotating cylinder 310 to rotate；Second motor 402 drives the second runner 406 to rotate by the second rotating shaft 404, thus driving lower rotating cylinder 320 to rotate.Two motors work alone, thus realizing the independently rotated of upper rotating cylinder 310 and lower rotating cylinder 320.
Preferably, the first rotating shaft 403 and the second coaxial nested setting of rotating shaft 404, it is possible to reduce shared space, black box can be simplified simultaneously.
The initial position of main piston 505 position between the 3rd inner casing porose area 204 and the 4th inner casing porose area 205, lower floating piston 504 rides on inner casing dividing plate 203.Thus, the first chamber 211 is constituted between unidirectional excess flow valve chip module 502 and upper floating piston 503, the second chamber 212 is constituted between upper floating piston 503 and lower floating piston 504, constitute the 3rd chamber 213 between lower floating piston 504 and main piston 505, between the cylinder bottom of main piston 505 and damping inner casing 200, constitute the 4th chamber 214.
When vehicle craspedodrome state, the position that the second bearing 332 that main piston 505 is between the 3rd inner casing porose area 204 and the 4th inner casing porose area 205 flushes, all porose areas are in opening.When wheel contacts up with protruding road surface, car body and tire do close motion, and the relative damping inner casing 200 of main piston 505 moves upward, the 3rd inner casing porose area 204 discharge damping fluid to exocoel.Along with main piston 505 moves upward, the 3rd inner casing porose area 204 area is gradually reduced, and the pressure of the 3rd chamber 213 gradually rises, and damping fluid overcomes the elastic force of the second spring 507, pushes lower floating piston 504 open, the second inner casing porose area 202 strengthen the discharge capacity to exocoel；Meanwhile, the damping fluid of exocoel enters the 4th chamber 214 by the 4th inner casing porose area 205, makes main spring compress.When wheel walks to protruding apex, main piston 505 stop motion, thus the distress resolves that main piston 505 is to the second chamber 212, second spring 507 promotes lower floating piston 504 airtight with inner casing dividing plate 203, stoping damping fluid to flow out from the second inner casing porose area 202, now main piston 505 terminates up and changes into descending.
When wheel cross protruding apex descending time, the relative car body of wheel does away from moving downward, the relative damping inner casing 200 of main piston 505 moves downward, and the damping fluid of the 4th chamber 214 enters exocoel by the 4th inner casing porose area 205, enters the 3rd chamber 213 again through the 3rd inner casing porose area 204.Owing to now the 3rd inner casing porose area 204 stream excessively is less, outer cavity pressure is made to raise, thus realizing the suppression effect of upspringing to main spring.Along with main piston 505 continues descending, the inflow-rate of water turbine of the 3rd inner casing porose area 204 constantly increases, the tension force of main spring is constantly decayed, now the 3rd inner casing porose area 204 area of passage and with main spring compress the inversely proportional relation of stretch amount, and make main spring variable and damping fluid close to constant value within the unit interval, thus give one critical damping value of main spring.
When vehicle walk to recessed road surface descending time, the relative car body of wheel does away from motion, the relative damping inner casing 200 of main piston 505 moves downward, the flowing hole area summation of the 3rd inner casing porose area 204 is close to main piston 505 area of section, the area of passage summation of the 4th inner casing porose area 205 is far longer than the area of section of main piston 505, thus ensureing that main piston 505 is in the interval motion of the 4th inner casing porose area 205, realize undamped state to greatest extent, do not interfere the quick extension of main spring, realize wheel quickly walk to the bottom on recessed road surface and do not lose the main spring purpose to the support of car body.Up in like manner undamped, because all moving objects are entirely instantaneous weight loss state walking to recessed road surface vehicle body, support force (the main spring that current vehicle adopts that the size of weightless sense is remaining after depending on the extension of main spring, extension stroke there is also damping not in addition, thus causing the tire moment liftoff).Therefore in this case ensure the more rapid motion of main spring, make car body obtain maximum support, do undamped design at this.
When automobile walks to bend, the effect of centrifugal force can make vehicle's center of gravity be moved out, and the main spring of inner side amortisseur is slowly upheld losing certain weight, and automobile chassis will be the trend slowly lifted.Now need lower rotating cylinder 320 rotates cut out in advance: now the design range of movement of main piston 505 should be travelled to and fro between in the region of the 3rd inner casing porose area 204, but has very big uncertainty.When main piston 505 moves to the lower section of the second bearing 332 and the 4th inner casing porose area 205 is closed, the 4th chamber 214 and the 3rd chamber 213 cut off can not be through, damping fluid can be made not flow, cause main piston 505 stuck, and therefore the design exists unidirectional excess flow valve 206.When wheel and car body do close motion, the relative damping inner casing 200 of main piston 505 moves upward, main piston 505 top and outer cavity pressure is made to raise, promote damping fluid to enter the 4th chamber 214 through unidirectional excess flow valve 206, and main piston 505 continues up the 4th inner casing porose area 205 that leaves and works at the 3rd inner casing porose area 204.Main piston 505 does back and forth movement at the 3rd inner casing porose area 204, and damping fluid comes and goes turnover the 3rd chamber 213 and the 4th chamber 214 through the part porose area of the 3rd inner casing porose area 204 and the gap of the second bearing 332.4th inner casing porose area 205 can not discharge damping fluid to exocoel, main piston 505 is promoted relatively not move downward by damping inner casing 200, also it is prevented that car body is lifted trend by upholding of main spring, it is ensured that at whole bend no matter car speed, how the constant damping effect of car body terrain clearance is without change.
For outside amortisseur, the weight that the main spring accepting the inner side amortisseur that inner side centrifugal force transfer comes is gradually decreased by the main spring of outside amortisseur, therefore significantly compressed making the main spring in outside amortisseur, car body significantly sinks, and the relative damping inner casing 200 of main piston 505 has significantly uptrend.All rapid movement vehicles are in bend, the main spring of outside amortisseur to bear the weight of car load more than 60 about percent, this technology is pursued maximum damping effect and is used super large stroke ultra-soft spring, meet vehicle and cross the protruding road surface moment compression its length target equal or close to protruding pavement-height, outside main spring can not bear inner side centrifugal force and shift the weight come, so outside main spring will have significantly compression vehicle body the trend of inclination of significantly sinking, this is the big unsurmountable reason that current vehicle can not use ultra-soft spring.
In order to stop this trend, upper rotating cylinder 310 rotates closes, and makes the second inner casing porose area 202 and the 3rd inner casing porose area 204 close, it is achieved the inner chamber pressurize in region corresponding to the second inner casing porose area 202 and the 3rd inner casing porose area 204.When this trend occurs, the weight of centrifugal force superposition acts on main piston 505, the inner casing oil liquid pressure in the second inner casing porose area 202 and the 3rd this section of region of inner casing porose area 204 is made to pass to lower floating piston 504 and upper floating piston 503, making the first spring 506 stress, collaborative main spring carrying car weight ensures that vehicle body does not roll.Now when outside meet protruding road surface up time, the relative damping inner casing 200 of main piston 505 moves upward, and make lower floating piston 504 driven under the effect of damping fluid, between main piston 505 and lower floating piston 504, relative distance does not change and simultaneously upper and lower, damping fluid promotes and moves on upper floating piston 503 and compress the first spring 506, first chamber 211 reduces, and damping fluid is expelled to exocoel from the first inner casing porose area 201；Along with continuing to go up a slope, main piston 505 and the synchronized continuation of upper floating piston 503 are up, compress the first spring 506, the first inner casing porose area 201 area of passage is caused to reduce, thus the first chamber 211 pressure raises, push unidirectional excess flow valve chip module 502 open, make damping fluid be discharged into exocoel from shunting porose area 207.Upper enforcement the 4th chamber 214 of main piston 505 increases, and the damping fluid of exocoel enters the 4th chamber 214 by the 4th inner casing porose area 205.
When wheel goes upward to protruding apex, main piston 505 is static in a flash, without pressure in the first chamber 211, shunting porose area 207 stops discharge damping fluid, unidirectional excess flow valve chip module 502 stops the damping fluid that shunting porose area 207 is discharged, the backtracking when main piston 505 is descending, so far up end.
When crossing protruding apex and being descending, unidirectional excess flow valve chip module 502 is closed and is tapped porose area 207 and closes, main spring is relatively distant from car body with wheel is descending, the main piston 505 moved downward also relative damping inner casing 200 moves downward, damping fluid can only from the first inner casing porose area 201 district by entering the first chamber 211, the first corresponding spring 506 and main spring all store huge compression stress, now the first inner casing porose area 201 provides only small inflow-rate of water turbine, the expansion force of the first spring 506 promotes upper floating piston 503, lower floating piston 504 damping inner casing 200 relative to main piston 505 has downward movement tendency, owing to the first inner casing porose area 201 stream excessively is less, thus causing the 4th chamber 214 to raise together with outer cavity pressure, first spring 506 and main spring tension force is big and the first inner casing porose area 201 cross flow little, the result that restriction interacts mutually obtains accurate damping value, movement velocity required for guarantee main piston 505 and piston rod 501, meet the steady numerous technical specifications of automotive safety.
To sum up, by at the different situations different operating to upper and lower two rotating cylinders, making amortisseur can meet the shock attenuation needs under various road conditions, the damped coefficient of amortisseur is all the time close to critical damping, reach spring and damp desirable coupling effect, better having adapted to the shock attenuation needs of automobile.
In another scheme of the present embodiment, it is possible to reference to crossing curved inner side amortisseur and crossing the structure of curved outside amortisseur so that it is only there is cylinder structure in a upper rotating cylinder or a lower rotating cylinder and each corresponding damping, thus meeting the damping needs of certain a single state.

For two elementary cells, as shown in Figure 6 and Figure 7, this amortisseur also includes the 3rd rotating cylinder 340.As such, it is possible to selectively one or two in rotating cylinder 310 and the 3rd rotating cylinder 340 is closed in pass, thus the hardness of larger range of adjustment amortisseur.
Further, when vehicle is crossed curved, first close and close rotating cylinder 310 load-bearing, and bend through in journey crossing, along with the increase of the increase of steering angle of vehicle, the increase and decrease of speed or bend angle, all can again increase vehicle outside spring load, now need to close the 3rd rotating cylinder 340 set up and carry out load-bearing, operation principle ibid, does not repeat at this.When additionally brake weight acts on amortisseur, identical with outer curve damping operation principle.
