Description
The present invention in conjunction with the suspension system of Improvement type frcition damper, is particularly to the suspension system of tool improvement frcition damper relevant for a kind of suspension system, is used to be subjected to the vehicle or the machine of random shock or stable vibrations.
Suspension System is used in various application, for example the shock absorbing that is experienced in the vehicle and machine run, vibrations or other interference.Typical application is for example used the shock absorbing that experiences at bicycle or locomotive.For example, when bicycle touched bump, indenture, stone, hole, hole or other obstacles, bicycle has developed into had Suspension System, the person of riding is experienced bump or vibrations provide buffering.The preceding pipe of the front fork of bicycle frame and handle, position, trailing wheel Rocker arm assembly and other positions of seat are pitched, are connected to the bicycle car before or after representative type, this bicycle Suspension System be used in.
The damping system of bicycle Suspension System also is widely known by the people, for example licenses to people's such as Tuner US Patent 5,456,480, and it has disclosed a hydraulic damping Shock absorber that uses at bicycle car fork.Though this system has had welcome damping force characteristics, they are quite complicated and meticulous, and cost an arm and a leg.In addition, though the hydraulic damping system has improved alleviating their weight, and reduced the weight of damping liquid especially, but still wished to provide weight lighter system.Specifically, be desirable to provide a damping system that does not need damping liquid fully.Eliminate damping liquid and just wish to eliminate the potential possibility of leakage of the damping system of using damping liquid.Industry thus continue to exist need one simply, not expensive and weight-saving damping system, to be used for the bicycle Suspension System.
At present, the Shock absorber of most of used for vehicle is velocity response formulas, and oleo damper is a main flow in this field.For all liq, high-speed susceptibility is the intrinsic propesties of all kinds fluid.Therefore, the hydraulic damper nationality is by the resistance to flow of liquid by the hole, and bigger strength is arranged during than low speed when high speed.The essential disadvantages of this type Shock absorber is exactly to jump apart from ground or the road surface bump as a traffic worker, because bump connection speed height, so apparent very firm of this Shock absorber.When this elastic qualities moved towards whole bottom, this Shock absorber effect was fewer and feweri.This is because Shock absorber stops its self speed, and to become less efficient be zero up to speed, and these quality bounce-back and other directions of migration.
Because its high-speed sensivity, so the summation of an oleo damper produce power consumption is closely to close to be connected in operating frequency.Therefore generally be to need in conjunction with valve start in most in different speed fields, to reach wideer frequency range effect.This clearly makes the design of oleo damper complicated, and increases productive costs.
The US Patent 5,951,033 that licenses to people such as Winter has disclosed a frictional damping system that uses in the bicycle Suspension System.This frictional damping system has at least one pair of sliding members, a friction producing component is positioned between this sliding members, thereby one of sliding members rub to produce, and motion produces damping to the sliding members slide relative for the friction of friction producing component at least.This friction producing component can be located within the shell spare, and this shell spare is fixed in one of this sliding members, and other sliding memberss are faced and contacted to this friction producing component.This frictional damping system may be further designed to provider tropism's susceptibility, make the damped motion of this slip at first direction greater than damped motion in contrast to the second direction of first direction.So directional sensitivity can be by when the slip of sliding members, with respect to tilt one of them surface of this friction producing component moving direction.
On the other hand, traditional frcition damper has represented inappreciable speed sensitivity.In any case but, because " crisp " that it produces sense, so this Shock absorber is not too welcome.The tradition frcition damper combines a sliding plunger, and the size of this piston is bigger for the internal channel of a rigidity pipe, and piston is then at this passage axial motion.For making this piston begin to move, execute axial force at piston and must overcome maximum static friction force between this piston and the pipe along this pipe.In other words, when the axial force of bestowing piston during less than maximum static friction force, this piston will be not can be with respect to this pipe motion and this pipe and this piston show as together and be similar to a solid individuality.Under this state, the not support effect and seem too firm of this frcition damper.This is far from ideal, especially for the suspention of the vehicle.
Move along pipe when maximum static friction force and beginning that piston overcomes, do not considering under the piston velocity that this dumping force generally is a constant.A traffic worker jumps apart from ground or the situation of road shocks if we repeat, and this frcition damper begins when impacting to show that one is unlimited initial firm, then when the motion of the whole bottom of this elastic qualities, and dumping force maintenance constant.When impacting density hour, this Shock absorber may be played the part of a similar rugged construction simply and do not had the effect that cushion rubber is provided.On the other hand, if impact relative big of density, this damper does not then have effect, and is former because a constant and the low damping force that frcition damper produces.
So, need development one location sensitive formula Shock absorber, wherein dumping force depends on the position of elastic qualities with respect to non-resilient quality.When the input of a lot of energy and temporarily be stored in the spring, this spring large deformation and this elastic qualities are towards the motion of whole bottom.In this case, a higher dumping force is required and consumes this intake.When intake hour, this spring can not be out of shape too much on the other hand, and so produce a much smaller response force.In this case, this damping unit should be with a high resistant drag excessively response and the cushioning effect that jeopardize spring.Opposite, this damping unit should produce a much smaller dumping force according to spring force, and allows smooth-going this elastic qualities of buffering of this spring.In a word, this location sensitive formula Shock absorber can produce the response force that a dumping force is proportional to spring, rather than the strong speed according to moving mass.
The purpose of this invention is to provide a position-inducing shock eliminator, it can produce a dumping force that is proportional to this spring response force, and almost irrelevant with the speed of moving mass.
Another object of the present invention provides a position-inducing shock eliminator, and wherein this dumping force depends on the position of elastic qualities with respect to non-resilient quality.
In order to achieve the above object, position-inducing shock eliminator according to the present invention comprises that one contains the location sensitive damper of a upper end and a lower end shell spare, one sleeve pipe that invests this shell spare shroud inwall, at least one slidably saddle that is placed in this sleeve pipe, this saddle has first diameter, to be placed in the pilot bearing of sleeve pipe lower end; One is clipped in one first spring of this saddle and this pilot bearing; One center shaft is from the extension downwards of this saddle and by this first spring and this pilot bearing, this center shaft has one second diameter; One is embedded in the lining of shell spare upper end; One is connected in the carriage of center shaft and this saddle opposite side; One is placed in one second spring between this lining and this carriage; Wherein this bushing design is about as much as first diameter of this saddle for its bottom diameter and successively decreases towards the upper end.
The invention provides the design of an innovation, to reach the notion of above-mentioned location sensitive formula Shock absorber.This location sensitive formula Shock absorber comprises a hollow, cylindrical modules, and it has an internal diameter along axial change.One ring-type piece slides with respect to the inwall of above-mentioned hollow circuit cylinder, and the diameter of this ring-type piece is greater than the internal diameter of cylindrical assembly.When this saddle with respect to this hollow circular cylinder when endwisely slipping, this hollow circular cylinder and this saddle on diameter interference and the friction drag that causes will be played the part of the source of an expenditure of energy.At least one or two whole said elements will be by elastomeric material, and for example elastic body or plastic cement are made, with for smooth-going dumping force curve is provided.In a most preferred embodiment, this slip block is made by rigid material, and hollow column will be made on every side by investing a rigidity pipe in the gum sleeve.
When this slide block was parked in the lower end of this gum sleeve, the interference of diameter was minimum between gum sleeve and ring-type piece, and this to close the friction force impedance be very little.Therefore when this saddle began upwards to move with respect to hollow column, resistance to sliding at the beginning was very little.This resistance to sliding oblique line rising gradually then, because when this saddle moves axially to full compression, the interference of diameter increase slowly between this saddle and the gum sleeve.This friction force that increases has gradually been eliminated when should the tradition frcition damper beginning because of high stiffness, and produce from being fixed to " crisp " sense of sliding between conversion.
When the resilience of this system, this friction force is change of direction but still keep a large amount of immediately.When the lower end of this this gum sleeve of saddle migration, this dumping force reduces then gradually, and its mode of action is similar but in contrast to compression stroke.According to existing invention, the overall reaction of this Shock absorber comprises a spring one location sensitive damper.
An important feature of the present invention is to utilize the rubber sluggishness to be a kind of method of expenditure of energy.Need use part for high damping, the rubber sluggishness of rubber element is because of vibrations circulations is controlled in another passage that circulating distortion and this sluggishness are played the part of the energy damping.
Another feature of the present invention is in conjunction with making lubricant guarantee smooth-going conversion and the minimizing abrasion of dumping force on the friction force surface.The lubricant that is applied between contact interface fills up the irregular of surface and improves the ride comfort that slides.Lubricant also helps to alleviate any unstable friction force, and this friction force is common in and comprises in the elastomeric friction.For the possibility that further reduces wear, can on the stiffener mating surfaces, be coated with the last layer protective substance, for example iron husband dragon (teflon) (trade name PTFE polytetrafluoroethylene) or and so on thing.
Be apparent that very the location sensitive formula dumping force curve of this expectation can nationality can be influenced the saddle of friction force and reach by most different-diameters, material and roughnesss of surface.
The features and advantages of the present invention can be further understood in detailed description by following most preferred embodiment, and this embodiment indicates corresponding element with reference to several views of this accompanying drawing with corresponding figure number.

The first best specific embodiment of location sensitive formula Shock absorber of the present invention is depicted in Fig. 2.This location sensitive formula Shock absorber has mainly comprised a location sensitive formula damping, a main spring 11 and other elements.This damper comprises rigidity saddle 1, a shell spare 4 that is connected to center shaft 2 to have gum sleeve 3 and is fixed in its madial wall.Best, shell spare 4 is made the intensity of palpus and rigidity to have by metallic material.Should be appreciated that, have must intensity and the other materials of rigidity also can be used for making this shell spare 4.One lining 5 is fixed in the upper end of this shell spare 4, and a carriage 6 is fixed in the bottom of center shaft 2.In the application of locomotive, this lining 5 is to be connected on the main body of locomotive not in this demonstration), and this carriage 6 is to be connected on wheel or the locomotive on the unsprung block (not in this demonstration).
One little spring 12 is arranged on 14 of a packing ring 13 and pilot bearings, and this pilot bearing 14 is fixed on this shell spare 4, and center shaft 2 is by the line of centers of this bearing.Usually nationality is by pressing tight carriage 6, with the distance that shortens lining 5 and carriage 6 with main spring 11 precompressed.This precompressed load is passed through this packing ring 13, this saddle 1, is reached these center shaft 2 starts and balance by spring 12.The lower end that one a plastic cement big envelope 15 and a crown cap 16 are seated in this shell spare 4 together enters the chamber 17 of this shell spare 4 to prevent dust and water.
The invention is characterized in the non-definite value of internal diameter of this gum sleeve 3.In order to show the geometric profile of gum sleeve and saddle the best, Fig. 3 has shown the amplification profile of gum sleeve and saddle.As shown in Figure 3, it is maximum and successively decrease toward the upper end in the lower end that this gum sleeve 3 is designed to its internal diameter.Up to certain restriction, the internal diameter of gum sleeve 3 can not reduce again, because can cause the interference with center shaft.Should in directly crossed this be restricted to the upper end all will be maintained fixed.The upper end that one rubber draft gear 18 is placed in chamber 17 is to prevent that saddle 1 touches the metal surface when saddle 1 when upwards and outwards (tops-out) is to maximum displacement.
The strength placement property of main spring 11 can and get by Fig. 1 b estimation.Location sensitive formula Shock absorber overall response in conjunction with main spring 11 and this location sensitive formula damper then is shown in Fig. 1 c.Shown in Fig. 1 c, the response of making a concerted effort of this location sensitive formula Shock absorber is started from scratch in the position of null displacement, and along with displacement increases and increases gradually.This has eliminated traditional friction force damper because of the sense of " crisp " that conversion caused from the static friction to the cliding friction suddenly.
In most preferred embodiment, gum sleeve 3 is made up of 9,10 in two zones.In zone 9, has only saddle 7 gum sleeve 3 of may nipping, because saddle 8 tools one are less than the less diameter of the diameter of regional 9 minimums, so can't touch rubber surface.The rubber diameter in zone 9 reduces minimum, thereby causes friction force and significantly increase.This design-calculated feature is to bear to add all additional weights in the vehicle.Because of the resistance in zone 9 is relatively little, after each displacement cycle, elastic qualities is free to retract the static center of elastic qualities and main spring 11.
At regional 10 o'clock, because of the internal diameter of gum sleeve 3 diameter less than saddle 8, saddle 8 rubber bush 3 that begins to nip, this will cause than zone 9 increases more rapidly in the dumping force degree.And the internal diameter in zone 10 reduces faster than zone 9, thereby in big displacement, dumping force has more rapidly to be increased.This feature provides in the required dumping force level of desirable expenditure of energy.
The dumping force that produces when location sensitive formula damper is tilted under any circumstance as main spring 11, and this dumping force is to be proportional to spring force.In other words, the consumption of (circle zone of Fig. 1 c) energy is the gross energy (gross area above Fig. 1 c under the straight line) that is proportional to the input Shock absorber forever in each displacement cycle.This is that the present invention improves a little with respect to the key that known Shock absorber provided.
Under the normal circumstances, because the essential speed sensitivity of damper fluid, oleo damper shows strong velocity correlation.As a result, this liquid Shock absorber may be too firm under the high-frequency load, but not enough dumping force is provided under the low frequency load.In order to reach the performance of wanting down, a plurality of interior valves of normal introduction design in that wideband more is wide.This makes that the design of oleo damper is complicated and increases productive costs.It is main expenditure of energy source that location sensitive formula Shock absorber of the present invention utilizes friction force.Friction force is to the impedance much smaller than damper fluid of the susceptibility of speed.As a result, the present invention provides the damping of broad frequency range under low cost, and because of having eliminated the damping liquid of Shock absorber, so common problem relevant for fluid seepage is avoided.
Gum sleeve 3 the most handy rubber compositions, with resistance to wear, heat, chemical damage, and under continuous pressure, show low deformation set, so that consistent performance performance to be provided.Under needs high damping force situation, rubber composition has higher hysteresis loss in the cyclicity distortion, and may be as the extra ducts of expenditure of energy.
Another key character of the present invention is to make with lubricator to guarantee smooth-going conversion and the minimizing abrasion of dumping force on the friction force surface.The lubricant that is applied between the sliding interface of 3 of saddle 1 and gum sleeves fills up the irregular of surface and improves the ride comfort that slides.Lubricant also helps to alleviate any viscosity friction force, and this friction force is common in and comprises in the elastomeric friction.For the possibility that further reduces wear, can on the stiffener mating surfaces, be coated with the last layer protective substance for example iron husband dragon (teflon) (trade name PTFEpolytetrafluoroethylene) or and so on thing.
In the operation of the most preferred embodiment of Fig. 2, air will be inhaled in the chamber 17.In the stroke of compression, the air that is inhaled into is to be compressed, and causes higher air pressure.In the stroke that rebounds, air pressure reduces.This effect may become air bellow and assist main spring 11 so that the buffering of elastic qualities to be provided.Not wishing to have under the situation of air bellow, on center shaft 2 and saddle 1, passage aisle is set, be used for guiding air turnover chamber 17 to prevent cumulative stress.Fig. 5 shows this change place.
Fig. 4 shows the second embodiment of the present invention.Wherein saddle 22 and 23 is made by the elastic material of for example natural rubber, and hollow column 24 is to be made by similar nylon 6-6 (nylon6-6) or metal, though hollow column 24 is also to be made and can still be made by the elastic body among first embodiment of Fig. 3 by elastic body.In order still to produce the curve of location sensitive formula dumping force, the geometrical property of hollow column 24 still keeps, and promptly being has bigger internal diameter in the lower end and reduce gradually towards the upper end.
In Fig. 6, show the saddle of revising in the third embodiment of the present invention 1, this saddle comprises the elastic parts 21 that a rigid central part 19, four rigidity friction elements 20 and are attached to center piece 19 and friction element 20.Rigidity friction element 20 may be made by metal or plastic cement.In this embodiment, hollow column 24 will for example metal or plastic cement be made by the material of rigidity.When saddle when hollow column 24 up moves, elastic parts 21 provides the DE of running into the required adaptation of always tightening of passage.Preferable wear-resistant rigidity material provides the solution of elastic body wear problem, has therefore prolonged the service life of damper.In order to protect friction element 20 and hollow column 24, with resin such as iron husband dragon (Teflon) or similar this type of thing coat the contact surface of friction element 20 or hollow column 24 inwall or above-mentioned both all want.Aforementioned lubricated profit also can adopt.
Fig. 7,8 the 4th embodiment display position induction type Shock absorber are applied in the design of bicycle front-wheel suspention.This Shock absorber is made up of 50 of the interior pipes of a pair of slides within along outer tube 51.These two outer tubes are connected in bridging element 53, the action of these two outer tubes 51 synchronously of this element.The inside of pipe 50 in two springs 52 are placed at, and be fixed at metal piece 54 on the spring, and column cylinder 55 is fixed in the lower end, this column cylinder is fastened at outer tube 51 in 57.
The lower end of interior pipe 50 is a right angle and a circular-arc cross section 56 by special deformation.One is fixed in the rubber draft gear 58 of metal cylinder 55, is in order to prevent when interior pipe 50 arrives topmost the metallic contact in metal cylinder 55 and circular-arc cross section 56.Another rubber draft gear 59 is placed in the bottom of outer tube 51, in order to prevent when interior pipe 50 arrives bottommost the metallic contact in outer tube 51 and circular-arc cross section 56.
One rubber layer 60 is fixed on the surface of cylindrical metal cylinder 55, and the external diameter of this rubber layer 60 is minimum in the upper end, and increases gradually toward the lower end.The internal diameter in zone 56 and the external diameter of the upper end of rubber layer 60 are the same, therefore, when zone 56 arrives the upper end of rubber layer 60,56 surfaces that touch rubber layer 60, zone.
When interior pipe 50 moves down with respect to outer tube 51, zone 56 snaps into rubber layer 60 gradually, and the lower end interlock of past more rubber layer 60 is many more.Induction type dumping force in position is that nationality is produced by the friction force between zone 56 and the rubber layer 60 as a result.This dumping force also has location sensitive formula curve as shown in Figure 1.
