Abstract
A rubber crawler has a structure in which connecting members are sequentially fitted onto wing portions adjacent to each other without using steel cords for resisting tensile force applied to the rubber crawler. Accordingly, the rubber crawler of the present invention has excellent characteristics in that breakage of steel cords due to the tensile force can be prevented, and torsion of the rubber crawler can be reduced.
Description
Technical field
The present invention relates to be mainly used in the rubber belt track of vehicle for construction and civil engineering machinery, more particularly, relate to a kind of rubber belt track that adopts the tension members of brand-new structure.
Background technology
Always, the tension force that is applied thereto for rubber belt track is born is longitudinally buried steel cord underground therein as tension members.But, when making this steel cord form ring-type, can form superimposed portion according to usual way, therefore, there is such shortcoming in this rubber belt track: can make the operator feel vibration, and can not be adapted to higher moving velocity relatively.Because tension members is formed by steel cord, so obviously also have such problem, that is, it can rupture when being subjected to big tension force.
On the other hand, a kind of rubber belt track that does not adopt the steel cord structure is disclosed in TOHKEMY 20000-313371 communique.Yet wherein in the rubber belt track of being recorded and narrated, it is metal-cored all to be assembly parts, and thus, its manufacturing operation extremely bothers, and it has higher intensity hardly.That is to say, owing in the assembling process of metal-cored and tension members, need special attention, so its operation is relatively poor, in addition, owing on the position that is equivalent to metal-cored alar part, adopt two clavas, that is, adopt thinner material, aspect intensity, have problems so can predict it.In addition, also exist this claval link of connection when being subjected to stretching, relatively to be easy to problems such as extension in this structure, thereby need further improvement.
Thus, the applicant is carrying out the exploitation of the rubber belt track of newest structure, wherein, replaces steel cord always, and metal link is connected in the alar part of adjacent metal core as tension members.
In the rubber belt track of this newest structure, form the hole that connects usefulness at metal-cored alar part, and correspondingly adopt the link of two ends buckle, then in turn this dogging is combined in the hole and, and then it is embedded in the rubber and forms rubber belt track whole metal-cored ring-types that is connected to become.In such rubber belt track, owing to can not adopting steel cord to make it become ring-type as tension members, thus aspect vibration, obtained very big improvement, and obtained higher tensile strength.Even so, still in fact such rubber belt track is still waiting further improvement.
Summary of the invention
The present invention relates to the further improvement of new type rubber crawler belt, it is further simplified metal-cored structure, and makes the structure of engaging part more firm.
Rubber belt track of the present invention has: the rubber elastomer of ring-type; Metal-cored, this is metal-cored to be made of the projection in the interior week that protrudes from rubber elastomer and the left and right alar part that is embedded in the rubber elastomer; And flange, this flange is formed on the periphery of rubber elastomer, and wherein, the left and right alar part of adjacent metal core is by each chimeric two link and linking together in turn longitudinally thereon.
Because rubber belt track of the present invention has above structure, so, need not along rubber elastomer vertically bury steel cord underground as tension members, replace, with link metal-cored alar part is coupled together, with this link as tension members.And this link is configured on the left and right alar part in each mode of two on each alar part and these alar parts is linked together.Compare with the situation of always using steel cord and to have higher-strength, and metal-cored distortion is had bigger binding force.And, in rubber elastomer, be subjected to the link of tensile force and accept being embedded on the same plane from the metal-cored alar part of chain wheel driving power, can prevent from thus metal-coredly from rubber elastomer, to deviate from.
With regard to metal-cored, be easy to rotate in order to make link, the cross sectional shape with the chimeric position of link in the left and right alar part can be circular.In addition, also can make a side that does not contact link of alar part trapezoidal.Can prevent metal-cored swing revolution so effectively, shape with the position of link tabling in the metal-cored alar part can be made for, cross sectional shape of a side of its contact link is a circular, and the cross sectional shape that does not contact a side of link is trapezoidal.This makes when rubber belt track being wound on idle pulley and the sprocket wheel, can not make the gyroscopic movement of link can not get restriction, and, when producing bigger relative turning force between metal-cored and the link, maybe when producing oppositely directed therewith swing turning force, the trapezoidal dip plane of that side that does not contact with link usually of alar part contacts with link, thereby stops the further rotation under the above-mentioned situation.The angle of inclination of the dip plane that this is trapezoidal is 5～30 degree.
And what make alar part forms the different salient of cross sectional shape of cross sectional shape and fitting portion with the chimeric front end of link, can prevent from thus to make coming off of back link in assembling process or at rubber belt track.Thus, leading section is formed along the salient of the vertical of rubber elastomer or thickness direction extension.
In addition, also can make the position in the left and right outside of metal-cored projection have the salient that extends along fore-and-aft direction.This salient towards front and back at least one side protrude, and it forms flat condition usually.This salient part or integral body are embedded in the rubber elastomer.Because the cross sectional shape of alar part is a circular, so it rotates in rubber elastomer easily.And this salient has the effect that can prevent this rotation.This salient can be in the left and right outside that be close to projection, and the centre of alar part that also can be between link can also be at the front end of alar part.The left and right outside in projection forms under the situation of the salient that is flat condition, can make this salient expose (protrusion) from rubber elastomer and rail portion when becoming runner and travelling.These also are applicable to invention scheme described later about metal-cored formation.
As link, the preferable alloy goods according to the size of rubber belt track and the relation of tensile force, also can adopt plastic product under some occasion.This link has the engagement section at its two ends, and this engagement section has the inner peripheral surface of circular, and this engagement section is embedded in metal-cored alar part in turn.And, respectively use two links at metal-cored left and right alar part, so that tensile force obtains dispersion, and resist metal-cored distortion with this.Have following severally as the structure of this engagement section, that is, two sides become ring-type etc. to the structure of inner opening or at opposition side to the structure of inner opening or sealing in the same side, and wherein to become the intensity of structure of ring-type the highest in sealing.In addition, also can make a side of link have the par,, and this par is exposed from the caoutchouc elasticity surface and become rail portion when travelling so that this par and runner state in opposite directions is embedded in this link in the rubber elastomer.In addition, also can adopt the parts of other shapes as link, this point will describe in conjunction with the accompanying drawings in the back.Configuration as link can have various schemes, for example is configured to symmetrical scheme, non-symmetrical scheme, staggered scheme and the combination of using scheme or above-mentioned several schemes of second link.
The rubber belt track of employing second link of the present invention has: the rubber elastomer of ring-type; Metal-cored, this is metal-cored to be made of the projection in the interior week that protrudes from rubber elastomer and the left and right alar part that is embedded in the rubber elastomer; And flange, this flange is formed on the periphery of rubber elastomer.Wherein, be formed with embedded hole on the end of alar part, in the embedded hole of the end of adjacent metal-cored alar part, chimeric cross section is the bending front end of second link of " コ " word shape, thereby makes whole metal-cored linking together.
In addition, in some cases, runner travels on the inner peripheral surface of rubber belt track, under the other situation, on the alar part in the left and right outside of metal-cored projection guide rail is arranged.In addition, cross sectional shape that can be by changing metal-cored alar part or form salient thereon link can not be deviate from.These are applicable to each scheme among the present invention about metal-cored formation.
And metal-cored alar part there is no need one and is decided to be one, also can resemble to be divided into a plurality of forks the tuning fork, and link is entrenched in whenever respectively and sticks.This makes alar part integral body flatten, the useless rotation and the swing of alar part in the time of preventing to travel.More particularly, alar part can be for having and the structure of two forks that link is chimeric and extend the trifid structure of flap portion between two forks.
Rubber belt track of the present invention has above structure, it does not adopt steel cord always, thus, not only its intensity is significantly increased, and has simplified assembling operation and improved the stack-mounted reliability, in addition, in rubber elastomer, link and metal-cored alar part are buried underground at grade, can reduce twisted phenomena thus, and can reduce the metal-cored situation of deviating from from rubber elastomer that takes place.

The specific embodiment
Further describe embodiments of the invention below in conjunction with accompanying drawing.Fig. 1 is the birds-eye view of inner peripheral surface side of the rubber belt track of first example of the present invention.Fig. 2 is the lateral plan of Fig. 1.Fig. 3 is the birds-eye view of inner peripheral surface side of the rubber belt track of second example of the present invention.Fig. 4 is the lateral plan of Fig. 3.Fig. 5 is the cutaway view at A-A line place.Fig. 6 is the cutaway view at B-B line place.Fig. 7 is the cutaway view at C-C line place.
Among the figure, 1 is rubber elastomer, and it is the matrix of rubber belt track.In Fig. 1 and Fig. 3, this rubber elastomer 1 forms ring-type continuously on the above-below direction of paper.2 is metal-cored, is formed with a pair of protruding 3,4 of the inner peripheral surface that protrudes from rubber elastomer 1 on it, left and right alar part 5,6 is arranged at it.This alar part 5,6 is embedded in the rubber elastomer 1, and the cross sectional shape of this alar part 5,6 is circular.In addition, in example shown in Figure 3, be formed with salient (par) 7,7 in the outside of projection 3,4, this salient 7,7 comprises that the partial sum of the inner peripheral surface that is exposed to rubber elastomer 1 is embedded in the part in the rubber elastomer 1.This salient 7,7 has the function of the swing that prevents metal-cored front and back or left and right directions, and its surface is the rail portion of travelling for runner.
On metal-cored 2 alar part 5,6 of disposed adjacent, respectively be arranged with two links (10a, 10b) and (10c, 10d), they are staggered front to back arranges and chimeric with each alar part 5,6, thereby link together whole metal-cored 2, and these links (10a, 10b) and (10c, 10d) left-right symmetric in Fig. 1 is arranged.That is to say that chimeric link 10a, 10b are staggered front to back shape with these links 10a, the chimeric one-tenth of 10b on the alar part 5, link together metal-cored 2 thus.Link 10c, the 10d of alar part 6 sides also carries out chimeric with the same manner, left and right alar part 5,6 is connected with (10c, 10d) symmetrical shape with link (10a, 10b).Though do not illustrate, it is asymmetric that obvious link also can be configured to the left and right sides.
In addition, when this rubber belt track was wound on idle pulley and the sprocket wheel, because link is rigid body, so the distortion at position that is embedded with this link is less, the result did not inevitably have the distortion of rubber elastomer at the position of link to increase.At link with leave between the rubber elastomer of Width of this link, the difference of this distortion is bigger, causes producing on the rubber elastomer at this position this stretching and the strain concentrating that causes of compressive deformation because of repeatedly thus.
Thus, for example, if interior all sides and/or the outer circumferential side at the rubber elastomer 1 of the inside and outside Width that leaves link 10 forms depression B1～B4 as shown in Figure 8, then can avoid compressing repeatedly the strain concentrating that is caused, thereby can prevent the aging of rubber belt track, can improve the durability of rubber belt track.
For rubber belt track, when rubber belt track was distorted or is crossing protrusion on the tread, be full of cracks etc. took place in rubber elastomer 1 easily that cover link 10b, the 10d of and arranged on left and right sides.Consider this point, on rubber belt track, constitute flange 8a, 8b, flange 8a, 8b are constituted cover link 10b, 10d as shown in Figure 9.Thus, it is very thick that the rubber thickness of the outer circumferential side of link 10b, 10d becomes, even for example protrusion has collided on this position, external force also can be because of rubber elastomer ( flange 8a, 8b) obtains buffering and absorption, and can not making like that, big power is passed to link 10.Thus, the crack that caoutchouc elasticity produces can be reduced, and then the durability of rubber belt track can be improved.
Figure 10 is the birds-eye view of the variation of presentation graphs 9.In this embodiment, on the outer peripheral face of the link 10a, the 10c that are not covered, also be formed with heavy section 8c, thereby durability is improved by flange 8a, 8b.The thickness of this heavy section 8c can suitably be selected according to the size and the predetermined usage condition of rubber belt track.
Chimeric between link (10a, 10b, 10c, 10d) and metal-cored 2 the alar part 5,6, can according to circumstances as shown in Figure 11 link 10a, 10b, 10c, 10d be configured to left-right symmetric, at this moment, can use above-mentioned 8a, 8b as mentioned above like that, in addition, can be for example under the tread of not shown runner, add salient 8d in order to prevent to vibrate also.
Figure 12 is the transparent view of first example of expression link 10.That is to say that this link 10 forms flat ring-type, its two ends are made the inboard respectively and are roughly semi-round engagement section 11a, 11b.
As second example of link 10, as shown in Figure 13, also can make engagement section 11a, 11b in the same side to inner opening.As shown in figure 14, as the 3rd example of link 10, also can make engagement section 11a, 11b at opposition side to inner opening.
The the 4th, the 5th example as link, as Figure 15 and shown in Figure 16, in lateral plan, a side (being generally interior all sides of rubber belt track) 10x can be made flat part, the mediad inboard of opposite side (outer circumferential side) 10y is kept out of the way, inner face is made at two ends be circular engagement section 11a, 11b.In addition, though do not illustrate, much less also can adopt the link of spectacle.
Under situation about relevant link 10 being used in the rubber belt track, rubber elastomer enters this and keeps out of the way the position, thus, the rubber elastomer layer that has been increased by this volume from the external force of tread cushions and absorbs in the process of moving, thereby weakened the power that is applied on the link, and then also can reduce the generation of crackle on the rubber elastomer.Thus, can improve the durability of rubber belt track.
Figure 17 is the cutaway view of the main portion of the rubber belt track when adopting link 10 shown in Figure 15.Rubber elastomer 1 cover link 10 around.Because being formed with bending on the outer circumferential side of link 10 keeps out of the way face 10y, so therefore rubber elastomer 1 is full of (1a) herein extraly.Keep out of the way under the situation of face 10y the integral thickness of rubber elastomer 1 very thin (1b) not forming this bending.When the convex shaped part of tread side collides this face in the process of moving, buffering effect under the situation of rubber elastomer thin (1b) a little less than, cause rubber elastomer 1 to occur crackle easily.Yet, keep out of the way face 10y in this case being formed with bending, owing to exist bending to retreat face 10y, make the loading of rubber elastomer 1 therefore increase (1a).Like this, when convex shaped part collides this face, cushion and absorb by rubber elastomer 1, thereby make the power that is applied to link 10 be unlikely to big.Thus, can reduce rubber elastomer 1 situation of crackle takes place, and then can improve the durability of rubber belt track.
In order to improve gleyness, preferably on link 10, offer through hole.In example shown in Figure 12, on link 10, be formed with through hole 11c.By this structure, rubber is entered in curing process in the 11c of this hole, bondingly become more reliable thereby make.Obviously this through hole 11c is applicable to the link 10 of whole embodiment.
Figure 18 expresses other examples of metal-cored 2 alar part 5,6, and this figure is the cutaway view same with Fig. 5.In this embodiment, make every effort to, prevent metal-cored 2 swing revolution, improve travelling comfort and useful life longevity, and can prevent and take off wheel by constructing improvement to metal-cored 2.That is to say, be not circular 9a with the surface of link 10 contacted sides in the alar part 5, with this circle 9a mutually continuously front end narrow down and form trapezoidal 9b.And the leaning angle of establishing two dip plane 9c, the 9d of trapezoidal 9b is θ
1, θ
2, the tiltangle of outer circumferential side then
1Be substantially equal to the allowable angle of inclination when being wound on above-mentioned idle pulley and the sprocket wheel, and, the tiltangle of interior all sides
2For allowing the play angle of metal-cored 2 swing.Further specify angle θ
1According to the radius of the idle pulley of conduct coiling object and sprocket wheel and different, be generally 5 degree to 30 degree, angle θ
2For identical or than smaller angle (be generally 5 to 20 about degree) therewith.
And, metal-cored 2 alar part 5,6 must and link 10 be entrenched togather reliably, even in assembling process and be embedded in the rubber elastomer 1 and for runner travel the back both can not throw off.Thus, can form salient 13 as shown in figure 19 at the front end of alar part 5,6, perhaps in another example of metal-cored 2 of representing as Figure 20 along the salient 13 of the longitudinal extension of rubber elastomer, the perhaps salient 13 that extends along the thickness direction of rubber elastomer in other examples of metal-cored 2 of representing as Figure 21.
As mentioned above, the cross sectional shape of metal-cored 2 alar part 5,6 is a circular, and this shape makes it turn round in rubber elastomer 1 easily.Also there is such essentiality thus, that is, forms salients, and this salient is embedded in suppresses metal-cored 2 revolution in the rubber elastomer 1 at alar part 5,6.The situation of guide rail of the portion of travelling of salient in that example (par) 7 double as runners has been described in Fig. 3, but salient is not limited to this, as Figure 22 A to Figure 22 D and shown in Figure 23, at the substantial middle of alar part 5,6 or the front end of alar part 5,6, be formed on the upwardly extending salients in front and back (being generally the par) 7a, and this salient is embedded in the rubber elastomer 1 fully or partly, can eliminate the revolution problem of metal-cored 2 alar part 5,6 thus.In addition, salient 7a can be arbitrarily with respect to the position of alar part 5,6, it can show as from the inboard of alar part 5,6 and stretch out, or at the 7as that is located on the central portion, even this position also can be brought the plat part 7b that forms together by alar part 5,6 at above-below direction.Obviously, can be suitable for equally at the formed salient of the front end of alar part.Also can be formed with depression or hole etc. on the salient 7a (7as), so that it has the effect of anchor with respect to rubber elastomer 1.
Figure 24 is the birds-eye view of the improvement example of expression link 10, and Figure 25 is its lateral plan.In this example, be provided with tabular surface 10f, expressed the example that being provided with the tabular surface 10f that protrudes slightly among the figure in the side of link 10e.This par 10f can be used as above-mentioned salient, or at this point as the running rail of runner.
Figure 26 is the birds-eye view after expression fits together this link 10e and metal-cored 2, and the link 10e that has this par 10f by configuration replaces link 10a, 10c.From this figure as can be known, supported by cooresponding par 10f as the guide rail of the portion of travelling of runner, thereby can keep longer track, and then can guarantee effectiveness in vibration suppression.Obviously, need not form rail portion on one's body certainly, have the effect of simplifying shape and cost-cutting, and can also realize metal-cored lightness, be easy to advantage thereby have carrying metal-cored 2.
Figure 27 is the birds-eye view of inner peripheral surface side that alar part 5,6 is divided into the example of two fork 5a, 5b and 6a, 6b, and this figure has specially only drawn metal-cored 2 and the view of link 10g.And Figure 28 is the cutaway view at the D-D line place of Figure 27.
In the drawings, be provided with alar part 5a, 5b and 6a, 6b left and right, and they are embedded in the rubber elastomer.And link 10g forms flat ring-type.This link 10g is chimeric with alar part (5a, 5b) and (6a, 6b) in turn.Thus, the constituting of rubber belt track, metal-cored 2 and link 10g on the above-below direction of paper, be connected to become ring-type, this alar part 5a, 5b and 6a, 6b and link 10g are embedded in the not shown rubber elastomer with chimeric state.
The cross sectional shape of alar part 5a, 5b and 6a, 6b is circular, and this cross sectional shape is slightly less than chimeric surface (semicircle shape) 11a, the 11b of link 10g, and this makes it to be entrenched togather with link 10g and revolution smoothly.This rotating being characterised in that, the resistance after reducing like that as described above to be wound on idle pulley and the sprocket wheel.
And, though the cross sectional shape of metal-cored 2 alar part (5a, 5b) and (6a, 6b) self is circular, but owing in rubber elastomer, be embedded with two such alar parts, similar with the bigger situation of alar part width in fact, can reduce metal-cored 2 swing revolution significantly.In addition,, on alar part 5,6, be formed with protruding 5c for link 10g correctly being provided with and maintaining on the position of regulation, 6c, obviously this projection goes for whole embodiment.
Figure 29 is the birds-eye view with the inner peripheral surface side of an example of alar part trifurcate.That is to say, formed flap portion 5o, 6o between alar part 5a, 5b and 6a, 6b, and its cross section is flat condition at fore-and-aft direction, its length has also increased.Thus, alar part integral body (5a, 5b, 5o), (6a, 6b, 6o) can obtain and form the roughly the same effect of alar part of the bigger par of width, can weaken metal-cored 2 swing revolution thus.
Figure 30 is interior all side birds-eye vieies of rubber belt track, and wherein, rubber belt track is formed by connecting by the second link 10h that is different from above-mentioned link, and Figure 31 is the lateral plan of this rubber belt track, and Figure 32 is the cutaway view at the E-E line place of Figure 30.
10 for above-mentioned forming ring-type and being the link of flats of having illustrated, is formed with the roughly fitting portion of semicircular in shape at its two ends.Such link 10 is to be entrenched in turn on the metal-cored alar part 5,6 with two chimeric modes every one.On the other hand, the second link 10h is " コ " word shape of lengthwise, left and right kink 10h
1, 10h
2Be cylindric, with the two ends 10h of the second link 10h
1, 10h
2Be entrenched in by first link 10 in the hole 50,60 of one metal-cored 5,6 the front end in past, link together whole metal-cored 2 thus.Rubber belt track of the present invention is metal-cored 2 and link 10,10h under this state are embedded in the not shown rubber elastomer and form.In addition, these two kinds of links can be entrenched on the left and right alar part symmetrically, or can chimericly become shape interlaced with each other.
Employing is in the structure of each chimeric two link of left and right alar part, and not only the length of alar part is very long, and has two chimeric inadequate situations of link.In addition, adopt the rubber belt track of tension members always to have following problem, promptly, perhaps rubber belt track is distorted under the effect of external force, or rubber belt track is subjected to the effect of shearing force, thereby fracture takes place and so-called raw edges phenomenon occurs in the edge that causes the Width of rubber belt track, so durability is relatively poor.
Yet in this example, first link 10 links together alar part self, and the second link 10h with the front end of alar part as connecting portion, link together in turn metal-cored by the first such link 10 and the second link 10h.This trident alar part has following feature thus, that is, even because the length of alar part is shorter, also can make link keep enough intensity, and because can be from the horizontal chimeric second link 10h, so, simplified metal-cored connection.Further, because the front end of this second link 10h and alar part 5,6 is entrenched togather mutually, so, therefore and higher parts near the widthwise edges of rubber belt track, therefore exist rigidity, thereby can reduce the generation of raw edges phenomenon.And the second link 10h also has and prevents first link to left and right effect of deviating from, and the effect that metal-cored alar part is positioned.
In addition, though second link is entrenched in the hole of left and right outer end of alar part, also can be according to circumstances, such as shown in figure 33, make the left and right medial extremity of itself and alar part chimeric.Like this, when at the outer end of alar part and interior distolateral employing second link, can not use link 10.
In addition, second link can have such new feature,, in left and right outer end or the inner of alar part two holes or a Long Circle hole is set, with curve 10h that is
