Description
Technical Field
The invention belongs to the technical field of rubber tracks, and particularly relates to a centrosymmetric low-power-consumption rubber track.
Background
At present, most of commonly used rubber tracks are of a structure with core metal, namely, the metal core metal which is longitudinally arranged at equal intervals along the track is embedded in the track. The metal core is heavy and easy to induce vibration, and the metal core is easy to peel off from rubber under high speed or heavy load conditions, so that the metal core is only suitable for low speed and light load occasions, such as engineering machinery, low speed agricultural machinery and the like.
In order to meet the use requirement of high speed and heavy load, the rubber track needs to abandon the original structure depending on metal core. If the use requirement of high speed and heavy load is met by depending on the improvement of the sizing material formula, a series of problems of poor rigidity and strength of the crawler belt and the like can be caused, such as no metal core support and poor transverse rigidity of the crawler belt; the driving teeth are made of nonmetal rubber, and the rigidity and the strength are difficult to ensure.
In addition, the lack of the transverse rigidity of the rubber crawler without the metal core metal structure can also aggravate the inconsistent tensioning of the two sides of the crawler in the process of traveling, and cause the serious abrasion of the related structure at one side of the crawler. The main reason is that the structures on two sides of the crawler belt are asymmetrical, so that the bending rigidity of two sides of the crawler belt is inconsistent, and the two sides of the crawler belt are tensioned differently when the crawler belt is bent around the wheel, so that the crawler belt tends to have lateral displacement towards one side.

the invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
A centrosymmetric low-power consumption rubber track, as shown in fig. 1 to 6, comprises a track body 1, wherein rubber protrusions 2 (the rubber protrusions are used for driving or guiding the track and can be called as driving teeth or guiding teeth) are arranged on the inner side surface of the track body, reinforcing units 17 are arranged on the rubber protrusions, a cord layer 13 is arranged in the track body along the track traveling direction, and transverse reinforcing units 16 are arranged in the track body. The rubber lugs are typically arranged in rows, each row may be provided with one or more rubber lugs, the rows of rubber lugs being spaced apart in the length direction of the track. The reinforcing unit is arranged on the upper side of the transverse reinforcing unit, namely, the reinforcing unit is closer to the inner side of the track, and the part of the reinforcing unit corresponding to the rubber bulge extends into the rubber bulge, so that the strength of the rubber bulge can be effectively improved, and the requirement of heavy-load use is met.
The inner side of the crawler body is provided with a rubber bulge part, the outer side of the crawler body is provided with a denser rubber pattern bulge, and the crawler body, the rubber bulge and the corresponding rubber pattern bulge form a rigid part of the crawler. The inner side of the crawler body is provided with a part without the rubber bulge, the outer side of the crawler body is provided with sparse rubber pattern bulges, and the crawler body and the rubber pattern bulges form a flexible part of the crawler. The flexible part has bending rigidity obviously lower than that of the rigid part, and the flexible part mainly provides bending deformation when the crawler belt is wound, so that power consumption and heat generation when the crawler belt is wound are reduced. The rubber crawler belt provided by the invention is composed of flexible parts with low bending rigidity and rigid parts for providing transverse rigidity of the crawler belt in the length direction in an alternating mode.
The transverse spacing of the rubber bulges is consistent with the corresponding space of the flexible part to form a rolling surface so that the loading wheels and the like can pass through when rolling on the crawler. Generally, the reinforcing units are generally disposed on the raceway surface 15 and inside the rubber bumps (above the cord layer).
in an alternative example, the transverse reinforcing unit 16 comprises reinforcing elements 3 corresponding to rubber lugs in the track body, which are located in the track body corresponding to the rubber lugs and extend transversely of the track, significantly increasing the overall rigidity of the track. The reinforcing elements are typically disposed outboard of the cord layer.
In an alternative embodiment, the lateral stiffening unit may be a stiffening layer added to the flexible portion or to the entire track in order to increase the lateral stiffness of the flexible portion. The reinforcement layers are distributed transversely along the track, and in particular, the reinforcement layers may be added to the flexible portion or to the entire track, and when the reinforcement layers cover the entire track, the width of the reinforcement layers is slightly less than the total width of the track, but exceeds the distribution of the track rolling surface across the width of the track. The reinforcing layer is much less stiff in the length direction than in the width direction to facilitate bending. The reinforcing layer can be formed by bonding equal-length bars or wires with rubber or weaving other materials, and the length direction of the bars or wires is transverse (X) along the crawler belt. The bar or the wire rope can be made of metal wires, glass fiber rods and other high polymer materials or engineering plastics with better toughness.
Of course, other fabrics such as canvas, nylon cloth, etc. may be used for the reinforcement layer. The reinforcing layer is arranged close to the cord layer, can be positioned at any side of the cord layer, and also can be arranged at both sides, and for the condition of arrangement at both sides, the number of layers arranged at both sides of the cord layer can be equal or unequal. The reinforcement layer can significantly increase the lateral stiffness of the flexible portion of the track without significantly increasing the bending stiffness of the flexible portion.
In an alternative example, the reinforcing layers referred to by the above-mentioned transverse reinforcing unit comprise a first reinforcing layer 5, a second reinforcing layer 6 and a third reinforcing layer 7 arranged in that order from the inside towards the outside of the track body, said reinforcing elements 3 being located between the first and the third reinforcing layers.
In an alternative embodiment, the second reinforcing layer is arranged at intervals between every two adjacent reinforcing elements. The reinforcing element further increases the rigidity of the rubber track and homogenizes the ground pressure distribution of the track. The reinforcing element can be a metal plate, a metal rod, a glass fiber rod or a glass fiber plate, and other plates or bars made of high polymer materials or engineering plastics with good toughness. The length of the reinforcing element in the track is slightly less than the total width of the track, but exceeds the distribution range of the track rolling surface on the track width, and the width does not exceed the total width of the rigid part.
It should be pointed out that, the reinforcing element generally corresponds the rubber arch setting of each row, promptly, the reinforcing element is in between rubber arch and the rubber decorative pattern arch, evenly transmits the effort of bogie wheel etc. to the track to the rubber decorative pattern arch steadily, better assurance track whole atress balanced, the atress situation is better.
in an optional embodiment, the reinforcing unit comprises a plurality of reinforcing layers, specifically an upper flexible reinforcing layer 8 and a lower flexible reinforcing layer 9 which are sequentially arranged from the inner side to the outer side of the crawler body; a gap 10 is left between the upper flexible reinforcing layer 8 and the lower flexible reinforcing layer 9 which are positioned in the rubber bulges.
the single or a plurality of flexible reinforced layers penetrate through the inner part of the rubber bulge and connect the rubber bulge together through the flexible part along the longitudinal direction of the crawler belt so as to improve the toughness of the rubber bulge. The flexible reinforced layer is generally made of fiber fabric, such as canvas and nylon cloth, and may be formed by further weaving bars or wires with equal length with rubber bonding or other materials, and the length direction of the bars or wires is along the transverse direction (X) of the track. The bar or the wire rope can be made of metal wires, glass fiber rods and other high polymer materials or engineering plastics with better toughness.
In an alternative embodiment, in order to further increase the rigidity, toughness or fatigue strength of the rubber bumps, the reinforcing unit may be a reinforcing element with certain rigidity embedded inside the rubber bumps. Specifically, the first reinforcing element 11 is arranged on the upper surface of the upper flexible reinforcing layer, so that the guiding capability of the rubber protrusion is improved. Usually, the first reinforcing element is flat or extends through the track surface to the inside of each rubber protrusion of each row, and in the width direction of the track, the first reinforcing element exerts a structural reinforcing effect on each rubber protrusion, so as to mainly enhance the strength of the guide surface of each rubber protrusion. In addition, a second reinforcing element 12 can be arranged on the lower surface of the lower flexible reinforcing layer, so that the toughness and rigidity of the rubber bulge are improved. Typically, the second reinforcing element has a ridge 18 towards the inside of the track. Each reinforcing element is of a thin-wall structure and can be made of metal, plastic or other materials with certain rigidity and strength, and other fiber fabrics such as canvas and nylon cloth can be used as each reinforcing element.
The flexible reinforcing layers and the reinforcing elements are arranged at intervals in the rubber bulge, and the rigid part and the flexible part are in smooth transition, so that the rigidity and the toughness of the rubber bulge are reasonably matched, the stress concentration in the meshing process of the rubber bulge and a driving wheel (or a driving chain wheel) is reduced, and the bearing capacity and the fatigue resistance of the rubber bulge are improved.
In an alternative embodiment, the reinforcing unit extends transversely along the track, and a row of rubber lugs are connected together by the track above the cord layer by the track, and the reinforcing unit can be a single or a plurality of reinforcing layers extending transversely along the track, and the reinforcing layers penetrate through the rubber lugs and the raceway surface along the transverse direction (X) of the track, are arranged at intervals inside the rubber lugs, and smoothly transition between the rubber lugs and the raceway surface, so as to reduce stress concentration of the rubber lugs and the guide contact with a bogie wheel or a guide wheel or a driving wheel. The reinforcing layer is generally made of fiber fabric, such as canvas and nylon cloth, and may be formed by further weaving bars or wires with equal length with rubber bonding or other materials, and the length direction of the bars or wires is along the transverse direction (X) of the track. The bar or the wire rope can be made of metal wires, glass fiber rods and other high polymer materials or engineering plastics with better toughness. The reinforcing layer may also be made of metal, polymer material, engineering plastic, etc. in the form of a thin layer or sheet.
it should be noted that the rubber track structure provided by the invention adopts a symmetrical arrangement method, the symmetrical arrangement means that all structures on both sides of the track are symmetrical relative to the central plane of the track, namely all structures of the track on one side of the central plane of the track are completely the same as those on the other side after being mirrored through the plane, and it is required to be noted that the central plane of the track is positioned in the middle of the track width, is vertical to the track width direction and is parallel to the track length direction. Mainly comprises the following symmetrical forms:
a. the cord layers of the track are symmetrical along the center plane of the track. If the cord with S twist direction is adopted on one side of the central plane, the cord with Z twist direction and the same material and size is adopted on the other side, if a group of cord with S twist direction and a group of cord with Z twist direction are adopted on the other side, a group of cord with Z twist direction and the cord with S twist direction are also used on the other side at the same position, and the other arrangement forms are analogized in turn. Other materials with the same physical dimension can be used for the cord layer to meet the symmetry requirement.
b. The overall dimension of the crawler belt comprises the dimension and the appearance of the rubber bulges, the rubber pattern bulges and the like which are symmetrical along the central plane of the crawler belt body.
c. The rubber materials used at the symmetrical positions of the two sides of the crawler along the central plane of the crawler are the same.
d. The technological manufacturing and other methods of the symmetrical positions of the two sides of the crawler along the central plane of the crawler are the same.
e. The rubber bulges, the rubber pattern bulges, the reinforcing units and the transverse reinforcing units on the crawler body are symmetrically arranged on the central plane of the crawler body.
f. if the reinforcing unit and the transverse reinforcing unit are formed by adopting twisted wire harnesses and the like, and the wire harnesses are not parallel to the crawler in the transverse direction, the arrangement of the wire harnesses is considered according to the requirement that the cord layers similar to the crawler in the step a are symmetrical along the central plane of the crawler.
It should be noted that, if the reinforcing unit, the transverse reinforcing layer, the inner cord layer of the crawler belt body and the like are formed by the wire harness with the twisting direction, the wire harness with the S and Z twisting directions can be arranged in an alternate staggered mode and the like, so that the influence caused by asymmetry can be reduced to the maximum extent.
According to the rubber crawler belt provided by the invention, the rubber pattern bulges 4 are arranged on the outer side of the crawler belt body, in an optional embodiment, the rubber pattern bulges are distributed more densely corresponding to the rigid part of the crawler belt, and are distributed sparsely corresponding to the outer side of the flexible part of the crawler belt. Because the overall structure of the crawler belt is composed of rigid parts and flexible parts which are alternately arranged, when the crawler belt is surrounded, bending deformation is mainly provided by the flexible parts, the transverse rigidity is provided by the rigid parts, and the heating and power consumption are lower when the crawler belt is bent.
It should be noted that the rubber pattern lugs are arranged symmetrically about the track about a track center plane 14 (which is referred to herein as the center plane of the track in the middle of the track width, perpendicular to the track width, and parallel to the track length). The bending rigidity of the two sides of the crawler belt can be symmetrical, so that the two sides of the crawler belt are tensioned uniformly on a walking system.
When the product is processed and manufactured, a preformed vulcanization mold is generally used for positioning a hard element (for example, a rod, a plate or a thin plate, a thin-walled element and the like with higher rigidity) and performing preformed vulcanization together with rubber, after the preformed vulcanization, other flexible layers (such as fibers or similar cord layers and other structures) are laid on a preformed semi-finished product, and then glue is injected or placed on the flexible layers for further performing the pre-vulcanization or the normal vulcanization, so that a finished product is finally formed. The flexible layers have different spatial positions or are difficult to perform once and then laid completely after vulcanization, and a multiple-time performing scheme can be adopted. The vulcanization process can adopt a mould pressing or injection molding vulcanization mode, and can adopt sectional vulcanization or integral vulcanization.
The crawler belt has reasonable structural design, ensures the stable integral performance of the crawler belt through a symmetrical structural form, and is composed of the flexible parts with low bending rigidity and the rigid parts for providing the transverse rigidity of the crawler belt alternately, the bending rigidity of the flexible parts is obviously lower than that of the rigid parts, and the flexible parts mainly provide bending deformation when the crawler belt is wound, so that the power consumption and the heat generation when the crawler belt is wound are reduced, and the use performance is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
