Description
The present invention relates to a kind of link plate of the preamble according to claim 1.Other favourable configuration possibility of the present invention is described in dependent claims and claim arranged side by side.In addition, the invention still further relates to a kind of flat link chain and a kind of chain-driven unit of constructing under the situation of this flat link chain that comprising that under situation about using, constitutes according to link plate of the present invention.In addition, the invention still further relates to a kind of vehicle with this chain-driven unit.
Start the link plate of described type and flat link chain as known in every way by prior art as described in also wanting after a while.Known in addition, this link plate and using the flat link chain that constitutes under the situation of this link plate being restricted aspect its power transmission capacity and having possibility thus: at first link plate for example damages owing to the power peak value and lost efficacy.This inefficacy can be presented as breaking of this link plate, wherein, other each link plate that is arranged between the identical articulated elements begins to cause the inefficacy of whole flat link chain or break from this link plate, because must be born the power transmission responsibility of this link plate that breaks certainly together and bear stronger load thus.This stronger load makes each link plate more near the limit of its power transmission capacity, perhaps even surpass this limit.
Now, task of the present invention is, a kind of link plate and a kind of flat link chain that uses this link plate are provided, and this flat link chain has higher intensity.In addition, should reduce wearing and tearing and make the elasticity of link plate or flat link chain extend less.The present invention also should make the part that must assemble seldom make flat link chain.This realizes like this according to the present invention: the contact pin thickness of at least some link plates is constructed greatlyyer, promptly makes link plate according to the present invention thicker thus.
This makes in the chain hinge big and make the level and smooth otch share height with neat punching out face by putting face between the link plate and pressure piece or wobble-member.In addition, realize extraordinary perpendicularity between wobble-member or pressure piece and the link plate thus.By this neat by putting that face can reduce or even avoiding the shearing of chain thigh.Also can reduce and avoid edge surrender under the best circumstances by less pressure.
But with respect to punching out quality and wobble-member bending load or pressure piece bending load, contact pin thickness can not increase arbitrarily.What also will consider is that instrument cost and punching out thickness hypergeometric example relatively increase.
Additionally produce advantage in link plate configuration according to the present invention and the application in toothed chain thereof: the turning over effect that the moment between tooth and the contact pin causes of passing through when chain enters into gear is subjected to favourable influence, because contact pin is guaranteed with respect to the good vertical degree of tooth.Obtain the reduction of the shear load in the guiding and tooth portion preferably thus or avoid.In addition, produce less pressure thus, can reduce or avoid the edge surrender thus.
According to the present invention, the concrete dimension scale on some numerical value is proved to be particularly advantageous.Therefore for example particularly advantageously be that the ratio of pitch 1 and contact pin thickness d is in 3.7 to 5.5 the scope.Also advantageously, wobble-member height or pressure piece height h and contact pin thickness d are in 1.3 to 1.9 ratio.And it is particularly advantageous that the ratio of wobble-member width or pressure piece width w and contact pin thickness d is in the scope between 0.8 to 1.2.In addition, particularly advantageously be that the ratio that ring encloses width s of portion and contact pin thickness d is in the scope between 0.8 to 1.2.
As mentioned above, the present invention also relates to be used for especially transmission for vehicles, the flat link chain of vehicle transmission system or vehicle motor auxiliary drive, this flat link chain has a plurality of link plates that hingedly are connected each other by wobble-member or pressure piece, wherein, pressure piece distribute transverse to the longitudinal direction of flat link chain and on pressure piece and link plate, be configured with separately construct crookedly by putting face, pressure piece and link plate along these by putting face each other by putting with transmission power, the width that extends transverse to the longitudinal direction of flat link chain being arranged and has an arc length in the cross section of extending, observing on the longitudinal direction of flat link chain separately transverse to this width by putting mask.
For the flat link chain of said type, the application in the apparent vehicle drive unit and have different configurations surely.In as the application in the stepless awl dish chain speed change gear (CVT) of a transmission for vehicles part, pressure piece has the end face of special shaping, by the pulling force as frictional force between these end face transmission awl dishes and the chain.In other application of great majority in vehicle drive unit, flat link chain is a toothed chain, and promptly link plate has tooth at least one side, by the pulling force between these teeth transmission gears and the chain.For example by US-PS 4,906,224 is known in the prior art for this toothed chain.This toothed chain uses on a plurality of positions in vehicle drive unit, for example in full wheel transfer case, use, engine behind front wheel lateral arrangement formula speed changer (Front-Quer-Getriebe) at the axial distance that is used for jumping to differential mechanism uses, be used as the chain of the hydraulic pressure auxilitary unit of speed changer inside, as the valve mechanism Quality Initiative of explosive motor or as other auxilitary unit (coolant pump of vehicle, lubricating pump, air condition compressor, generator, starter motor, hybrid servo-motor, brake booster and similar device) chain.
The flat link chain of said type is made up of a plurality of link plates, and these link plates hingedly are connected each other by pressure piece.
Power between pressure piece and the link plate is delivered in this is being undertaken by putting on the face, these by put face and not only be configured on the pressure piece and also be configured on the link plate and pressure piece and link plate along these by putting face each other by putting.Pressure piece is also referred to as pin or bearing pin, and they respectively are inserted in two connecting piece perforations as waving hinge in couples, and these connecting piece perforations connect to a macropore usually at the chain that is used for conical disc winding contact transmission.
On pressure piece, be configured with different function faces.The pressure piece that in a hole of flat link chain, is located opposite one another on scroll zones or rolling surface each other by putting.When chain bends on this position to carry out the roll extrusion campaign according to the predetermined bending angle of pressure piece geometrical shape.
Pressure piece this pressure piece by put rest on the face link plate by putting on the face, thus, face between produce surface pressure by what put face and pressure piece by putting at link plate at this.These must satisfy a plurality of requirements by putting face.The surface pressure that is produced makes pressure piece not rotate in the hole of link plate owing to should also should not use as antitorque rotary device like this by putting face excessive and on the other hand by the moulding of putting face on the one hand.
For this purpose, known have segmentation by putting the flat link chain of face, described segmentation have two visibly different radiuses by putting every section in face.Therefore US 6277046 shows and has two by putting the flat link chain of face on pressure piece, and described have two different radiuses by putting mask.Realize antitorque commentaries on classics now by these different radiuses, thus, pressure piece does not rotate in the hole of link plate.Described another kind of known flat link chain among the US 5236399, this flat link chain is realized antitorque commentaries on classics like this: two different radiuses also respectively are being set on the face or are making the center of radius dislocation by putting.
Except this antitorque commentaries on classics, also must satisfy flat link chain resistance to fracture and durable requirement by putting face.For this purpose, the surface pressure in the contact area between pressure piece and the link plate does not allow to surpass predetermined value.According to understanding so far, this need have small curve and thus larger radius of curvature by putting face.Therefore,, need to increase radius of curvature, so that realize by putting reducing of contact pressure in the face according to previously described known flat link chain.
Unexpectedly confirm now, the existence that is not small radii of curvature (deep camber thus) is responsible for the appearance by the pressure stress peak value in the contact area of putting face by putting face and link plate of pressure piece, produces local peak stress but strengthen ground in the transition region between different curvature radius.This makes and recognizes now, in known flat link chain, from a radius of curvature to the transition region of another radius of curvature, there is the obvious stress peak value, has the obvious stress peak value when exactly under this transition tangentially, is not promptly having the situation of bending, distributing.
A corresponding view has been shown among Fig. 1 of accompanying drawing.This illustrates: with the small radii of curvature of K mark with the transition region between the larger radius of curvature of G mark in pressure stress peak value of appearance, but pressure stress in the zone of small radii of curvature than not obvious height in the zone in larger radius of curvature.Promptly this understanding is as follows: be not that small radii of curvature is responsible for the appearance of the high pressure stress peak value in part, but represent one to disturb the position from a radius of curvature to the transition region of another radius of curvature.
Promptly verified, although the pressure piece that reverses when bending at flat link chain is provided with rolling surface, but produce pressure piece by putting reversing on the face, promptly, even when flat link chain has antitorque rotary device, in the surface of contact zone of the link plate of flat link chain and pressure piece, also relatively rotate, by putting shearing motion is taking place on the face promptly between pressure piece and link plate, this causes that at the transition portion from a radius of curvature to another radius of curvature promptly the curvature of link plate is no longer coordinated mutually with the curvature of pressure piece by putting the mistake coupling of face.
This shearing makes the face carrying in the contact area between pressure piece and the link plate carry out the transition to the line carrying of investigating and make the contact pressure in this contact area improve thus on the width of pressure piece now, so that appears among Fig. 1 of accompanying drawing the pressure maximum value shown in this at this.Reckon without this situation so far,, only be adapted to big as far as possible radius of curvature so that the load in the surface of contact zone between reduction pressure piece and the link plate because according to usual understanding.
Therefore there is the goal conflict:, also must resist pressure piece reversing on the other hand with respect to link plate by putting the requirement that to consider the surface pressure of permission in the face zone on the one hand.
Flat link chain can be configured to vehicle drive unit, this flat link chain has a plurality of link plates that hingedly are connected each other by wobble-member, wherein, pressure piece distribute transverse to the longitudinal direction of flat link chain and on pressure piece and link plate, be configured with separately construct crookedly by putting face, pressure piece and link plate along these by putting face each other by putting with transmission power, the width that extends transverse to the longitudinal direction of flat link chain being arranged and have an arc length observing on the longitudinal direction of flat link chain in the cross section of extending transverse to this width by putting mask separately has at least three zones with different curvature by putting face along this arc length.
Therefore, in other words, obtaining one has such by putting the flat link chain of face, these have at least three zones with different curvature by putting face along the longitudinal direction observation along flat link chain in a cross section of its length of curve, avoid the big transition in the curvature thus, but still be provided with zone with small radii of curvature and larger radius of curvature, so that resist pressure piece reversing with respect to link plate.
Therefore understanding changes: opposite with known understanding, not to depend on providing as far as possible little curvature in the face zone with larger radius of curvature by putting, but give pressure piece by putting face the different curvature of sufficient amount is set by what put face and link plate, but avoid causing the curvature transition of heavily stressed peak value.
Propose according to a favourable further configuration at this, the ratio of maximum curvature and minimum curvature is at least the factor 2.Realize by this configuration: exist pressure piece with respect to enough antitorque commentaries on classics of link plate and with have also enough little curvature transition by putting face together along the feature that its arc length or length of curve are provided with at least three different curvature, thus by put in the zone of curvature transition, do not producing on the face do not allow high pressure stress.
Also propose at this, curvature can remain unchanged respectively along arc length at each intra-zone at least three zones, promptly observes in a cross section along the axis longitudinal direction of flat link chain, and length of curve or arc length can be made up of at least three arc sections.Realize thus: the transition decomposition between the different curvature of segmental arc diminishes, investigate as radius of curvature, pressure piece at the flat link chain that is used for vehicle drive unit, compare from 1mm to 5mm with the big radius transition that causes heavily stressed peak value, the transition of each radius of curvature for example can be arrived 5mm then at first from 1mm to 3mm.
Also propose, curvature changes along arc length separately at each intra-zone at least three zones.In other words, this means in three different zones inconstant curvature is set, but curvature for example can change continuously in each zone.Thus, in the axial longitudinal section of flat link chain, observe, can form by spiral pieces by putting face, the curvature of these spiral pieces and thus radius of curvature change continuously along arc length.Except these spiral pieces, axially observing in the longitudinal section, also can form by putting the face shape by oval section, the curvature of these oval sections changes between minimum value and maximum value continuously.And except that these shapes, the section that also can form by hyperbola or parabola as the section of length of curve or complete be commonly along arc length have curved section by putting face, the second dervative of these curved sections rises.
In addition, propose according to a further configuration, have curved section by putting face along arc length, these curved sections are positioned at the middle part of arc length to a great extent along the arc length of minimum profile curvature radius.
Realize by the middle part that minimum profile curvature radius is arranged in to a great extent arc length: maximum curvature is positioned at the outside by the end regions separately of putting face, realize in this pressure piece thus: be arranged in by the layout of the end regions separately of putting face with minimum profile curvature radius and compare, this layout rigidity more greatly and crooked thus less.Therefore, be uniformly distributed on all link plates arranged side by side each other at the unbending situation lower pulling force of pressure piece, link plate obtains higher durability and flat link chain can transmit higher pulling force generally.
Realize thus by such flat link chain: in by the transition region between the different curvature radius of putting face, no longer produce significant contact stress transition.And the antitorque commentaries on classics of pressure piece in the hole of link plate compared with known flat link chain and is improved.

Fig. 2 of accompanying drawing shows a part of known CVT flat link chain 1, and this CVT flat link chain is made up of a plurality of wobble-members or pressure piece 2,3 and link plate 4.Show the zone of using the A mark in Fig. 2 in Fig. 1 of accompanying drawing enlargedly, therefore, Fig. 1 has described pressure piece 2 and link plate 4.
Fig. 3 of accompanying drawing shows now according to the pressure piece 5 of the flat link chain 7 of first form of implementation and the zoomed-in view of link plate 6.
As directly appreciable like that, between pressure piece 5 and link plate 6, be configured with two regional 8 and 11 by putting face, wherein, by put face zone 8 by on the pressure piece 5 by put on face 9 and the link plate 6 complementally construct constitute by putting face 10.By put face zone 11 in a similar manner by on the pressure piece 5 by putting forming on face and the link plate 6 by putting face.
Fig. 3 of accompanying drawing shows first form of implementation according to flat link chain of the present invention now, wherein, on the pressure piece 5 by putting face 9 and complementally being configured with zone by putting face 10 on the link plate 6 therewith with different curvature.Now in order diagrammatically to express these curvature, in Fig. 3 of accompanying drawing, zone with different curvature respectively dots out by means of corresponding different radius of curvature 13,14,15,16, wherein, each radius of curvature 13,14,15,16 vertically is drawn on the zone with different curvature respectively, for naked eyes just is difficult to the different curvature visually recognized by putting on the face 9,10 so that can diagrammatically represent.
But Fig. 3 of accompanying drawing directly shows, curvature regional medium and small than in radius of curvature 14 in the zone of radius of curvature 13, thus, radius of curvature in zone 13 than in zone 14 greatly.Radius of curvature with corresponding manner in zone 15 than in the zone in 14 littler and therefore curvature in zone 15 than big in zone 14.Thus, pressure piece 5 by put face 9 and therewith complementally link plate 6 by putting face 10 by putting in the face zone 8 along having had three different curvature by the arc length or the length of curve of putting face 9,10.Fig. 3 additionally also illustrates, and also is being configured with another 16, the four zones, the 4th zone along arc length and has the radius of curvature 16 different with radius of curvature zone 13,14,15 by putting on the face 9,10.Also have the different zone of curvature by putting face zone 11 with corresponding manner, wherein, three zones with different curvature only are set at this.
Fig. 4 of accompanying drawing shows the pressure piece according to the flat link chain of second form of implementation now, and wherein, this pressure piece also relates to the pressure piece of the flat link chain that is used for conical disc winding contact transmission.
With reference number 17 mark rolling surfaces, pressure piece 5 is gone up roll extrusion by this rolling surface being positioned at the pressure piece on opposite (also relate to pressure piece to) in this pressure piece 5, and wherein, this basic bit-type can be found out by means of Fig. 2 of accompanying drawing.Pressure piece 5 also has two by putting face 18,19, these by put face be arranged in a unshowned link plate structure complementally by putting on the face.The top have a point by putting face 18 with the B mark, have the curvature maximum value at that point, promptly this point is also perpendicular to having its minimum value so that represented radius of curvature is described by putting face 18.Increase at both direction from this B radius of curvature, thus, curvature is diminishing by putting on the face 18 continuously from a B on the both direction.Increasing and on the direction of arrow 21, increasing according to oval section on the direction of arrow 20 at this from a B radius of curvature according to spiral pieces.
Fig. 4 below show an analogue by putting in the face 19 from having peaked some C of curvature, wherein, radius of curvature is increasing according to a hyperbolic line segment on the direction of arrow 22 and is increasing according to a parabolical branch line segment on the direction of arrow 23.
Fig. 5 of accompanying drawing and Fig. 4 show a view similarly, and wherein, the pressure piece 24 shown in Fig. 5 of accompanying drawing relates to the pressure piece of a toothed chain, and this toothed chain for example can be used as the toothed chain that is used for drive unit or uses as the toothed chain of conveying equipment.Pressure piece 24 also has a rolling surface 25, this pressure piece on this rolling surface can pressure piece right with the pressure piece corresponding setting of this pressure piece on roll extrusion.Pressure piece 24 also have a top by put a face 26 and a below by putting face 27.By putting this such selection that is configured in of face 26, make on by the both direction of putting face 26, to increase along the arc length of also representing by brace 12 from a B radius of curvature (this radius of curvature is also perpendicular to representing by putting the facial contour with dashed lines).Radius of curvature is increasing at both direction from the point (corresponding to minimum profile curvature radius) with maximum curvature with the C mark with corresponding manner by putting on the face 27.
As seeing in addition, when on by the arc length of putting face or length of curve, observing, by the maximum curvature of putting face and thus minimum profile curvature radius roughly be distributed in when putting the middle part of face, can realize the resistance to compression design of pressure piece.
Fig. 6 of accompanying drawing is used for this respect is made an explanation now.With letter b or C also respectively the mark top by put on the face and below by put on the face, separately by putting the point that face inside has maximum curvature and has minimum profile curvature radius thus.As directly can finding out by means of this accompanying drawing, some B or C roughly are positioned at the middle part of arc length 28, and the zone with radius of curvature shown in the dotted line also is distributed in the below of this arc length.Though the front is stated, the point with maximum curvature roughly is positioned at middle part (measuring) by putting face along arc length on arc length 28, verified, when a B or C are arranged in 40% to 60% scope D of arc length 28, reaches similar favourable effect.The below of this scope and pressure piece overlaps by 30 to 60 degree angular ranges of the tangent line of putting face, and wherein, this 30 to 60 is spent angle and measure between tangent line 29 and chain direct of travel 30.If point now separately with maximum curvature by putting face be positioned at arc length 28 total length 40% to 60% or be positioned at tangent line 29 and spend with respect to 30 to 60 of chain direct of travel 30, then obtain rigidity and unbending thus pressure piece, this also makes the pulling force of available flat link chain or toothed chain transmission increase.
Fig. 7 of accompanying drawing also show now between the pressure piece 5 of flat link chain (wherein, the notion of flat link chain also comprises toothed chain) and the link plate 6, selected below distributes by the contact pressure of putting in the face in the view.Showing that the contact pressure maximum value of giving prominence to shown in Fig. 1 disappears by distribute contact pressure with flat link chain of the contact pressure of the known flat link chain of with reference to the accompanying drawings Fig. 1 more immediately between distributing according to Fig. 7.In order to represent to distribute by the contact pressure of putting in the face, in two accompanying drawings, selected normalized each other representation, thus, the length of arrow separately also represent by put face the amplitude of the contact pressure in the point of corresponding observation.Can directly find out thus, disappear according to the significant contact pressure maximum value of Fig. 1 by means of visual inspection.
