Description
Technical field
The present invention relates to the transmission band of a kind of preceding sections according to claim 1.
Background technology
Transmission band as above is often used between two axles in power train to transmit driving force.A pair belt wheel walked around by transmission band, and each belt wheel is separately positioned on different axles.By the CONTACT WITH FRICTION between the first belt wheel and transmission band, the rotary motion of the first belt wheel is converted into the translational motion of transmission band.By the CONTACT WITH FRICTION between transmission band and the second belt wheel, the translational motion of transmission band and then be converted into the rotary motion of the second belt wheel.Therefore second belt wheel is brought driving by the first belt wheel by transmission.
A kind of commonly known purposes of above-mentioned transmission band is in the buncher for sulky vehicle (such as pedal motorcycle).In this variator, each belt wheel all includes a pair pulley sheaves, and each pulley sheaves is respectively provided with inwardly angled side, in order to the side surface of Contact Transmission band.According to two wheel discs distance relative to each other, transmission band runs along belt wheel with bigger or less radius.By changing the distance of in driving pulley or in driven pulley pulley sheaves, the gear ratio between two belt wheels can under a definite limitation unrestricted choice.
Generally, in pedal motorcycle, transmission band is applied to has the stretch-draw element including elasticity or rubber ring, is embedded with multiple stretch-draw fiber in this ring, it is possible to provide protection coverage between stretch-draw fiber (layer) and rubber ring.Multiple supporting members are arranged on rubber ring, are supported on a pair belt wheel for by stretch-draw element, and each supporting member is respectively provided with a pair contact surface, in order to support the CONTACT WITH FRICTION with a pair pulley sheaves.Supporting member is made up of relatively hard and wear-resistant material (usually thermoplastic, such as polyamide), in order to the forced contact of reply and transmission pulley durably.Each supporting member is positioned in the recess in the outer surface of the rubber ring being arranged at stretch-draw element, and each supporting member is therefore relative to longitudinally fixed at transmission band of stretch-draw element.Owing to rubber ring is provided with recess to hold the part of supporting member, therefore its nominal altitude reaches the diameter of stretch-draw fiber or several times of height.
Nearest open WO2014-080288A1 and WO2014-080289A1 teaches, and rubber ring can save from the stretch-draw element of traditional transmission band.In this case, stretch-draw element is made up of one or more stretch-draw cores or line, and described stretch-draw core or line are made up of crossed fiber, such as aromatic polyamides, it is possible to is applied or is otherwise provided with cover layer.If applying this coating or cover layer, its thickness will be typically smaller than the height of stretch-draw core, and under any circumstance, this coating or cover layer are not provided with the described recess of the rubber ring being applied in above-mentioned traditional transmission band.If it addition, use single stretch-draw core, just it is generally arranged to multiple placed side by side, spiral coiling.In this particular case, required fixing by the friction between them, by by these adhering components or otherwise adhere to and/or make supporting member be provided with the stretch-draw core-thrusting stretch-draw element and therefore sealed with the stretch-draw core of stretch-draw element part realizes in the vertical between stretch-draw element and supporting member.
Although this existing transmission band avoids due to the deformation of rubber ring and the energy loss that causes in operating process, and additionally reduce manufacturing cost by exempting rubber ring, but with include this rubber ring as compared with the traditional transmission band of a part for its stretch-draw element, it was observed that reduce service life to a certain extent.Based on this observation, applicant sets about studying the main cause in the service life of this reduction, and designs solution based on thus obtained understanding.Therefore, the expectation of the disclosure and purpose are to improve the service life of existing transmission band.
Summary of the invention
According to the disclosure, in existing transmission band, namely when there is no rubber ring, the stretch-draw element produced on belt wheel and when being wound around around belt wheel with arc at transmission band bends between the supporting member concentrating on transmission band, and this bending is distributed more step by step around the belt wheel arc of this winding in traditional transmission band.Because stretch-draw element is rigidly fixed to supporting member, does not therefore bend can produce at these supporting member places in a longitudinal direction thereof.Therefore the bending needed for stretch-draw element produces the edge at supporting member.Therefore stretch-draw element track in the belt wheel arc being wound around can be seen as by the multiple sharp turns in succession separately of the straight section corresponding to supporting member position or bending.Therefore, the bending stress in stretch-draw element concentrates on described bending place therein, thus endangering its durability and/or service life.Advantageously reduce this bending stress, bend more step by step along the belt wheel arc being wound around especially by making stretch-draw element.
In the first alternate embodiment of the transmission band according to the disclosure, the longitudinal direction (i.e. circumference) along transmission band that curves through of stretch-draw element provides interval (i.e. gap) advantageously to be affected between supporting member in succession.Due to this measure, the bending of stretch-draw element produces in the gap between supporting member, it is achieved thereby that stretch-draw element more progressively, namely more slow bending.Preferably, this gap be supporting member along at least the 10% of described longitudinal yardstick (i.e. the thickness dimension of supporting member), and the twice or more of this supporting member thickness can be reached.Preferably, with absolute value, this gap is 1-5mm length, is more preferably 2-4mm, and the thickness of supporting member combined in particular is 2-9mm, it is preferred to 3-6mm.
In a practical embodiments of this first embodiment, protection coverage puts on the stretch-draw core of stretch-draw element in the described gap between supporting member in succession.By this cover layer, curve through described in stretch-draw element and the gap between supporting member in succession is more equally among distributed and is advantageously affected.In this aspect preferably, the thickness of cover layer is maximum at the adjacent supporting member place of cover layer, and gradually reduces towards the gap center of cover layer thinnest part.Thus, at least relative to the stretch-draw element bending of the gap location between stretch-draw element leap supporting member, the stretch-draw element bending in the edge of supporting member is suppressed.
Alternatively, in the second alternate embodiment of transmission band, curving through of stretch-draw element provides elastic component so that stretch-draw element is advantageously affected in the bending of the position (also) of supporting member between supporting member and stretch-draw element.Therefore, this elastic component achieve more progressively, namely more slow stretch-draw element bending.This elastic component can be implemented by the layer of elastic compressible material (such as synthetic rubber), and it adheres to supporting member, adheres to stretch-draw element or adhere to both.
In a practical embodiments of this second embodiment, elastic component is also implemented which the described protection coverage of the stretch-draw core of stretch-draw element.Fully encapsulate at elastic component, namely assembly stretch-draw core, the layer thickness of elastic component can be changed, and thus the bending of stretch-draw element will focus on the relatively thin part place of elastic component.Preferably, in this thin section gap that to be arranged in the first embodiment of transmission band between support component set.

Detailed description of the invention
Fig. 1 illustrates the buncher 2 including the first belt wheel 100a and the second belt wheel 100b.Each belt wheel 100a, 100b are separately mounted on belt shaft 200a, 200b.Transmission band 1 runs on the two belt wheel 100a, 100b.
Each belt wheel 100a, 100b all include a pair pulley sheaves 101a, 101b.Each pulley sheaves 101a, 101b are respectively provided with the contact surface 102 of inclination, and the contact surface 102 of described inclination is in the face of the contact surface 102 of another pulley sheaves 101a, 101b.In each belt wheel 100a, 100b, pulley sheaves 101a, 101b can at corresponding belt shaft 200a, 200b axially with respect to moving each other, thus can change two pulley sheaves 101a, 101b contact surface 102 between distance.Owing to the contact surface 102 of two pulley sheaves 101a, 101b relative to each other separates in the radially outward direction of belt wheel 100a, 100b, therefore make two pulley sheaves 101a, 101b be close together and force transmission band 1 to be moved radially outward to continue to run with larger diameter.Vice versa, makes transmission band 1 radially-inwardly to move away from each other two pulley sheaves 101a, 101b, in order to continues to run with more minor diameter.
When the first belt wheel 100a is driving pulley, the second belt wheel 100b is driven by transmission band 1 by the first belt wheel 100a.Ratio section between first belt wheel 100a and the second belt wheel 100b can run residing radius with 1 each place in belt wheel 100a, 100b and change by changing transmission along different directions.
Fig. 2 illustrate the transmission according to prior art with 1 a part.Existing transmission band 1 includes multiple supporting member 50, each supporting member 50 be substantially plate shape and along transmission with 1 longitudinally opposed layout.At the sidepiece place towards opposite shaft orientation, supporting member 50 is provided with contact surface 54a, 54b, contacts for the surface 102 that contacts with pulley sheaves 101a, 101b.The two contact surface 54a, 54b relative to each other inclined position, in order to the gradient on the contact surface 102 of wearing band wheel disc 101a, 101b.Existing supporting member 50 includes end section 20 and top section 30, limits slot-shaped opening 55 between end section 20 and top section 30.The part of supporting member 50, the part especially extended radially inward from the edge 56 front principal plane of supporting member 50 are convergents, in order to adjacent supporting member 50a, 50b relative to each other tilt, so that transmission band 1 can bend.
Transmission also includes the stretch-draw element 10 extending through the opening 55 of each supporting member 50 with 1.Stretch-draw element 10 include in transmission band with multiple coiling 41a, 41b provide stretch-draw line 40, each coiling respectively along transmission with 1 whole circumference extend in the vertical.Coiling 41a, 41b of stretch-draw line 40 position abreast, thus being substantially filled with the width of the opening 55 of supporting member 50.Stretch-draw line 40 can be made up of metal, plastics or aramid fibre, and when being made up of aramid fibre, line 40 can weave or have other braiding structure.It is used as other materials, such as carbon fiber or glass fibre.Stretch-draw element 10 can include coating or the cover layer of stretch-draw line 40, in order to increases its durability and/or abrasion resistance (when being made up of fibrous material) particularly in stretch-draw line 40.
In order to make existing transmission band 1 run by expection, supporting member 50 is fixed to stretch-draw element 10, for instance by being arranged on binding agent between supporting member 50 and stretch-draw element 10, by being provided with reciprocal interlocking portion or being likely to only be fixed by friction.As described in WO2014-080288A1, along transmission with 1 longitudinal extension thereof measure time, adjacent, namely supporting member 50a, 50b of arranged in succession are fixed to stretch-draw element 10 with the mutual spacing place of about 0.1mm.
In existing transmission band 1, time between transmission is with 1 pulley sheaves 101a, the 101b being clamped in corresponding belt wheel 100a, 100b, transmission with 1 around belt shaft 200a, 200b with produced by arc winding place stretch-draw element 10 bending concentrate on transmission with in the multiple relatively anxious kinks between adjacent support elements 50a, 50b of 1.Each this kink place in stretch-draw element 10, sizable bending stress produces in each coiling 41a, 41b of stretch-draw line 40.According to the disclosure, if stretch-draw element 10 realizes bending more progressively, so that it may improve durability and existing transmission band 1.
In the transmission according to the disclosure with (this first embodiment schematically shows in figure 3) in first embodiment of 300, sizable mutual spacing or gap 3 are arranged on transmission with between supporting member 350a, 350b in succession of 300.Due to this gap 3, therefore stretch-draw element 310 is given the space of bending, so that produced stretch-draw element 310 local buckling radius advantageously increases, and bending stress advantageously reduces for the transmission band 1 of prior art.In shown transmission with in the example of 300, with supporting member 350a, 350b compared with the transmission thickness with the size in the longitudinal direction of 300, i.e. supporting member 350a, 350b, gap 3 is of the same size with approximate in the longitudinal direction of 300 in transmission.By applying this big gap 3, transmission can be obviously prolonged with the service life of 300.But, at least the small gap 3 of 1mm, ten times of namely commonly used interval or at least the 10% of described thickness just can improve this service life significantly and advantageously originally.
In the transmission according to the disclosure with (this second embodiment schematically shows with the sectional view with supporting member 350 of the stretch-draw line 40 of stretch-draw element 310 in the diagram) in second embodiment of 300, elastic component is arranged on the transmission according to the first alternative embodiment with in the gap 3 between supporting member 350a, 350b in succession of 300 according to the disclosure.In particular, this elastic component 4 is by relatively the making according to suitable (compliant), the i.e. material (such as rubber) of elastically deformable of stretch-draw line 40 being attached to stretch-draw element 310.By this elastic component 4, the bending of required stretch-draw element 310 is by the gap 3 between supporting member 350a, 350b of being advantageously distributed in succession.Preferably, this elastic component 4 fully assembly stretch-draw element 310, otherwise, the surrounding that stretch-draw element 310 will be exposed between supporting member 350a, 350b.In order to strengthen further stretch-draw element 310 this progressively, the bending of more equal distribution, it is seen that elastic component 4 thickness diametrically reduces from corresponding supporting member 350a, 350b towards the center in gap 3 or middle M, also as shown in Figure 4.By this latter feature, curving through of required stretch-draw element 310 increases its local buckling radius and is distributed best in a longitudinal direction thereof.
About transmission with 300 this rear one, second new embodiment, it should be noted that, by not providing elastic component 4 diametrically between the stretch-draw line 40 of stretch-draw element 310 and the end section 20 of supporting member 350 and top section 30, bending required between the stretch-draw line 40 of stretch-draw element 310 and the end section 20 of supporting member 350 and top section 30 is not adversely affected.Therefore, new transmission can be advantageously fixed to together with these posterior components of 300 in the way of WO2014-080288A1 or WO2014-080289A1 instructs, namely by applying binding agent betwixt and/or by carrying out welding with (ultrasound wave) welding.
In particular, it should be noted that this required bending between stretch-draw element 310 supporting member 350 can be modified in stretch-draw line 40 by aromatic polyamides and Fypro being all merged into.Certainly, other components and/or material can be applied to optimize some characteristic of stretch-draw line 40, but, the original Fypro by adding little share in the aramid fibre of main composition part, it has been found that be greatly improved the stretch-draw line 40 bending (especially when applying ultrasonic bonding) relative to supporting member 350.More particularly, aramid fibre now mainly determines the stretch-draw intensity of line 40, and Fypro mainly determines the line 40 bending strength relative to supporting member 350.
In the transmission according to the disclosure with (the 3rd embodiment schematically shows with the sectional view with supporting member 350 of the stretch-draw line 40 of stretch-draw element 310 in Figure 5) in the 3rd embodiment of 300, wherein, elastic component 5 between the end section 20 and top section 30 of supporting member 350, the edge of (Fig. 2) opening 55 of stretch-draw element 310 traverse with relatively according to suitable, namely the form of the Embedded Division 5 of the material (such as rubber) of elastically deformable be included therein.By providing this Embedded Division 5 (as shown by arrows, this Embedded Division 5 can be compressed by the stretch-draw line 40 of stretch-draw element 310), stretch-draw element 310 is flexible in the position (also) of supporting member 350, so that produced stretch-draw element 310 local buckling radius advantageously increases, and bending stress advantageously reduces for the transmission band 1 of prior art.
In the transmission according to the disclosure with (the 4th embodiment schematically shows with the sectional view with supporting member 350 of the stretch-draw line 40 of stretch-draw element 310 in figure 6) in the 4th embodiment of 300, wherein, elastic component 6 with stretch-draw line 40, relatively according to suitable, namely the form of the cover layer of the material of elastically deformable be included therein.Stretch-draw element 310 be longitudinally oriented, the section of this cover layer 6 that includes being added into stretch-draw line 40 fits in inside the opening 55 of supporting member 350.By providing this cover layer 6, stretch-draw element 310 is flexible in the position (also) of supporting member 350.Additionally, also as shown in Figure 6, the layer thickness of described cover layer 6 reduces from supporting member 350 towards being arranged on the transmission middle M with the gap (the first alternative embodiment according to according to the disclosure) between supporting member 350a, 350b in succession of 300.
