Fig. 1 is the birds-eye view of ground plane one side of rubber belt track in the past, and Fig. 2 is the a-a line section drawing of Fig. 1.In addition, Fig. 3 is illustrated in drive wheel 31 and the bearing wheed 32 and rubber belt track 21 state of contact on the running gear that uses rubber belt track 21.As shown here, the outside face in the main body 22 of rubber belt track 21 is separated with the compartment of terrain in its strip length direction and is formed with a plurality of plate teeth 23.Under the state of hanging, rubber belt track 21 is drawback movement by drive wheel 31 transferring power at this, along with the drawback movement of this rubber belt track 21, contacts with ground successively around the plate tooth 23 of extension portion.
At this moment, the edge portion 24 of the end face of plate tooth 23 knocks with ground at first, produce to impact thus, by the further ground connection successively of plate tooth 23 (edge portion 24), and produces this impact repeatedly, forms vibration, has rubber belt track 21 problem of drawback movement reposefully.Certainly much less the rolling on the rubber belt track inner peripheral surface of bearing wheed 32 can produce bigger vibration.
Usually, in the inside of the main body 22 of rubber belt track 21, be embedded with arbor 25 accordingly with the position of plate tooth 23, plate tooth 23 and arbor 25 superimposed parts constitute high rigid portion 28.On the other hand, the part of the main body 22 in plate tooth 23 interval each other on the strip length direction does not only have plate tooth 23 but also does not have arbor 25, so become the rigidity low rigid portion 29 lower than high rigid portion 28.
Therefore, this deflection when deflection on above-below direction of the rubber belt track 21 when bearing wheed 32 is on the high rigid portion 28 and this bearing wheed 32 are on the low rigid portion 29, the deflection when being on the low rigid portion 29 is big, causes deflection that difference is arranged.Therefore, when rubber belt track running gear was walked, bearing wheed 32 carried out up-and-down movement with the amplitude of deflection difference, has produced vibration by this up-and-down movement.The vibration of carrying out up-and-down movement by bearing wheed 32 like this and producing, its reason is that the poor rigidity of high rigid portion 28 and low rigid portion 29 is big.In addition, in above accompanying drawing, the 26th, for the connecting hole that cooperates with not shown sprocket, the 27th, be formed on the arbor 25, to side-prominent projection of the interior week of rubber belt track 21.
Summary of the invention
By the vibration that rubber belt track running gear produces, make operator's travelling comfort variation, and can cause being equipped on electronic machine on operating machine etc. by this vibration and produce fault, misoperation.The object of the present invention is to provide a kind of rubber belt track that can reduce the vibration that takes place in the walking.
Purport of the present invention is a kind of rubber belt track that reduces vibration, is to be made of non junction ring-shaped rubber elastomeric material, arbor, tension element, plate tooth; This arbor is embedded in the rubber elastomer with a determining deviation on the length direction of this rubber elastic material, this tension element is from this arbor of outer encirclement and be embedded in the rubber elastomer equally, this plate tooth at the outer circumferential side of rubber elastomer to form with the same spacing of the spacing of arbor, it is characterized in that, the aspect of the plate tooth at the position relative with arbor is straight line roughly on the Width of rubber elastic material, about the cross sectional shape of the plate tooth on the length direction of rubber elastic material is roughly the symmetry trapezoidal, the width on the length direction of rubber elastic material of arbor and plate tooth about equally, the position of this plate tooth is by towards the direction opposite with working direction dislocation configuration.
And specifically, be such rubber belt track: the position of plate tooth is configured to towards the direction opposite with working direction dislocation 1/6～1/3 spacing, in other words, and in the configuration that misplaces of the end face of plate tooth and the almost nonoverlapping scope of arbor.
As previously discussed, in the running gear that rubber belt track of the present invention has been installed, on the length direction of rubber belt track, its whole rigidity difference diminishes, therefore, up-and-down movement when rolling on vibration in the time of can reducing around being hung on drive wheel ground connection and the inner peripheral surface of bearing wheed at rubber belt track can reduce vibration thus.

The specific embodiment
As above-mentioned embodiment explanation in the past, in the running gear that uses rubber belt track, the propulsive effort of machinery transmits with drive wheel, arbor, plate tooth, ground-surface order, and the vibration edge during walking passes to body in the path in contrast to this.Particularly the spacing at spacing that makes arbor and plate tooth is uniformly-spaced and relatively disposes in the rubber belt track in the past of this arbor and plate tooth at same position in overlooking, because plate tooth and arbor form high rigid portion, so the power during the edge portion ground connection of the plate addendum face in the walking is delivered to arbor easily, this is a present situation.
This be because, when the edge portion ground connection of plate addendum face, even the plate tooth causes the caoutchouc elasticity distortion, because plate tooth and arbor relatively dispose, so just be directly delivered to arbor from the concavo-convex vibration that produces of for example walking surface of ground plane one side.
The present invention is the relation that resets the arbor of rubber belt track and plate tooth, the transmission of not ignoring propulsive effort, reduce the rubber belt track of the generation of vibration, in the configuration of arbor and plate tooth, the position that makes the plate tooth is towards direction dislocation configuration this plate tooth opposite with working direction, and it is disposed at low rigid portion side, and make plate tooth easy deformation so that its vibration can not be directly passed to arbor during the edge portion ground connection of plate addendum face.That is, allow the action of plate tooth, make the rigidity of high rigid element descend thus, reduce the poor rigidity of high rigid element and low rigid element, make the rigidity of the two approaching, thereby can reduce the vibration that produces by the bearing wheed up-and-down movement owing to misplacing.
In addition, even under the situation of the configuration dislocation that makes the plate tooth, because the plate tooth produces distortion during the edge portion ground connection of plate addendum face, have certain effect, but preferably plate tooth and arbor do not constitute high rigid portion jointly, preferably its vibration can not be directly delivered to the structure of arbor, that is, and and the end face of plate tooth (edge portion) and arbor non-overlapping structure in overlooking.
Embodiment
Followingly be described in more detail the present invention with reference to accompanying drawing.Fig. 4 is the birds-eye view of ground plane one side of rubber belt track of the present invention, and Fig. 5 is the A-A line section drawing of Fig. 4.Among the figure, the 1st, rubber belt track of the present invention, the 2nd, the rubber elastic material of non junction ring-type, the 3rd, be formed at the plate tooth of outer circumferential side, the 4th, the edge portion of the end face of plate tooth 3.The 5th, be embedded in arbor in the rubber elastic material 2 with a determining deviation, the 6th, be used for the connecting hole that cooperates with the tooth of drive wheel.Plate tooth 3 in this example clips connecting hole 6 and is divided into left and right sides two parts, is the shape of a straight line but form accordingly at Width with arbor 5, and the cross section on its length direction forms roughly trapezoidal.In addition, among the figure not shown towards rubber elastic material 2 length direction and the steel cord buried underground.
So, the rubber belt track 1 shown in here, plate tooth 3 forms roughly straight line on the Width of rubber elastic material 2, on the length direction of rubber elastic material 2, symmetry trapezoidal roughly about the cross sectional shape of plate tooth forms.And this plate tooth 3 is being fastened with the pass of arbor 5, and the two width on the length direction of rubber elastic material 2 about equally.For such plate tooth 3, its position (with respect to arbor 5) is disposed to the direction opposite with the working direction of rubber belt track about 1/4 spacing that misplaces.In this case, should the end face that makes plate tooth 3 not with arbor 5 equitant scopes in respect to the position of arbor dislocation ground configuration plate tooth.
Fig. 6 is the figure of the state of expression when above-mentioned rubber belt track 1 formed running gear around being hung on drive wheel 11, bearing wheed 12 and not shown idle pulley.And, fasten in the rubber belt track 1 and the pass of bearing wheed 12 especially, originally can arrive the arbor 5 of the high rigid element of formation and the overlapping part of plate tooth 3, but make plate tooth 3 towards opposite side dislocation with working direction, even so to this position, can former state directly not go up unchangeably on the high position of rigidity yet, because plate tooth 3 is retreated, so rigidity step-down, even when contacting with walking surface in the edge portion 4 of the end face of such plate tooth 3, this plate tooth 3 is not overlapping with arbor 5, so its action can not moved by arbor 5 bigger restrictions, can reduce the rigidity at this position thus yet.
On the other hand, because plate tooth 3 is misplaced towards an opposite side with working direction,, can make the rigidity at this position improve so on the contrary so it is outstanding to low rigid element.Therefore, the poor rigidity of the two diminishes, and the up-and-down movement of bearing wheed 12 tails off, and can reduce the generation of vibration.
Fig. 7 is the birds-eye view of ground plane one side of the 2nd embodiment of expression rubber belt track of the present invention.In this example, plate tooth 3 is to clip connecting hole 4 and to be divided into the left and right sides two-part, be make its only a side (being the right side in the figure) the plate tooth towards with the example of the opposite side dislocation of working direction of rubber belt track.When being installed to rubber belt track on the vehicle, according to circumstances different with vibrative degree in the outside in the inboard of vehicle sometimes, this example is with dealing with this situation.Certainly, a side of the plate tooth 3 that misplaced is positioned at has the side ground of considerable influence that this rubber belt track is installed to vibration.
Being described as follows of bis in the accompanying drawing:
