Abstract
Description

[0001] The invention relates to the technical field of rubber crawler track production for crawler vehicles, in particular to an improved anti-deformation high-tooth anti-derailment rubber crawler track. Background Art
[0002] In the existing technology, rubber tracks, as an important walking component, are widely used in various vehicles and mechanical equipment, especially in occasions that require good passability and high ground pressure distribution, such as agricultural machinery, engineering vehicles and military vehicles. However, traditional rubber tracks often face problems such as derailment, deformation and severe wear in complex terrain or high-intensity use conditions. These problems not only affect the running stability and safety of the vehicle, but also greatly shorten the service life of the track.
[0003] In particular, the core metal structure of traditional rubber tracks is often simple in design and has a single tooth shape, which leads to the lack of tight engagement between the track and the drive wheel during driving, especially when turning or climbing, which requires greater traction, and is prone to derailment. In addition, due to the lack of an effective limiting structure between the core metals, the track is prone to deformation when subjected to lateral force, further exacerbating the risk of derailment.
[0004] Therefore, in order to improve the anti-derailment performance and anti-deformation ability of rubber tracks, the industry has been seeking a new track structure to overcome the shortcomings of the existing technology. In particular, in application scenarios that require frequent crossing of complex terrain, high loads, and high stability, higher requirements are placed on the performance of rubber tracks. Summary of the invention
[0005] The invention aims to provide an improved anti-deformation high-tooth anti-derailment rubber crawler track to improve the stability and durability of the crawler track.
[0006] To achieve the above object, the technical solution adopted in the present invention is: provide an improved anti-deformation high-tooth anti-derail rubber crawler, the improved anti-deformation high-tooth anti-derail rubber crawler comprising: A plurality of core metals, the core metals are neatly arranged, the core metals include a bridge, a guide protrusion, a tooth wing, and an auxiliary guide rail, the guide protrusion is arranged on both sides of the bridge, the guide protrusion includes a wide end and a narrow end, and the wide end and the narrow end of the guide protrusion on the adjacent core metals are interlocked; the tooth wing is arranged on the outer side of the guide protrusion; the upper surface of the auxiliary guide rail is flat, and the auxiliary guide rail is arranged on the tooth wing; A rubber layer is coated on the surface of the core gold.
[0007] In one embodiment, the auxiliary guide rails on the tooth wings on both sides extend forward / backward respectively, so that the auxiliary guide rails form a staggered structure.
[0008] In one embodiment, a first reinforcing rib is provided between the auxiliary guide rail and the guide protrusion; and a second reinforcing rib is provided between the auxiliary guide rail and the tooth wing.
[0009] In one embodiment, upwardly protruding rubber reinforcement ribs are provided on both sides of the rubber layer.
[0010] In one embodiment, the top of the bridge is in the shape of a horizontally arranged cylinder, and the bottom of the bridge is in the shape of a square platform.
[0011] In one embodiment, an X-shaped slit is provided on the rubber layer between two adjacent bridges.
[0012] In one embodiment, the core gold is phosphated.
[0013] In one embodiment, the method for preparing the rubber layer material comprises the following steps: S1, premixing treatment; placing the styrene-butadiene rubber and nitrile-butadiene rubber of the mass ratio components and the mixed solvent in an internal mixer for internal mixing treatment; S2, a first stage of mixing; the premixed rubber obtained in S1 and the carbon black, white carbon black, tear-resistant resin, and wear-resistant reinforcing filler of the mass ratio components are placed in an internal mixer for mixing; S3, two-stage mixing; mixing the rubber compound obtained in S2 and the activator of the mass ratio component and placing them in an internal mixer for mixing; S4, refining; mixing the rubber compound obtained in S3 with sulfur and accelerator in a mass ratio and placing them in an internal mixer for internal mixing; S5, flat plate vulcanization: placing the refining rubber, core gold and cord prepared in S4 in a flat plate vulcanizer device for vulcanization treatment.

In addition, the special arrangement and structural design of the core gold, combined with the comprehensive coating of the rubber layer, provide excellent anti-deformation support for the crawler. This structure can effectively disperse and withstand the pressure and impact from the ground, maintain the stability of the crawler shape, extend the service life, and reduce the performance degradation or damage caused by deformation. The flat upper surface design of the auxiliary guide rail and the reasonable layout of the tooth wing further enhance the contact stability and grip between the crawler and the ground or the drive wheel. This not only improves the passability of the crawler on uneven ground, but also ensures the stability and controllability of the vehicle when driving at high speed or climbing steep terrain.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] See also Figure 1 to Figure 2 The embodiment of the present application provides an improved anti-deformation high-tooth anti-derailment rubber crawler, comprising a plurality of core metals 1 and a rubber layer 2. The core metals 1 are neatly arranged, and the core metals 1 include a bridge 11, a guide protrusion 12, a tooth wing 13, and an auxiliary guide rail 14. The guide protrusion 12 is arranged on both sides of the bridge 11. The guide protrusion 12 includes a wide end 121 and a narrow end 122. The wide end 121 and the narrow end 122 of the guide protrusion 12 on the adjacent core metals 1 are mutually engaged; the tooth wing 13 is arranged on the outside of the guide protrusion 12; the upper surface of the auxiliary guide rail 14 is flat, and the auxiliary guide rail 14 is arranged on the tooth wing 13; the rubber layer 2 is coated on the surface of the core metal 1.
[0024] By interlocking the wide end 121 and the narrow end 122 of the guide protrusions 12 on the adjacent core metals 1, not only the stability of the track in a straight state is enhanced, but also when engaged with the drive wheel, this interlocking structure can form a more solid limiting effect, effectively preventing the track from derailing due to external forces during driving, greatly improving the operating safety and reliability of the rubber track on complex and changeable terrain.
[0025] Specifically, the inner and outer sides of the wide end 121 and the narrow end 122 of the guide protrusion 12 are both planes, and the planes are parallel to the length direction of the crawler track, and the rubber layer 2 at the guide protrusion 12 is relatively thin, and the two side surfaces are kept as planes parallel to the length direction of the crawler track. When the road wheel moves on the crawler track, the side surface of the guide protrusion 12 can play a good guiding role (the side surface of the guide protrusion 12 is set as a plane parallel to the length direction of the crawler track, which can greatly increase the effective guiding area of the guide protrusion 12, thereby improving the guiding effect), and greatly improve the stability of the crawler track during driving.
[0026] Optionally, the bridge 11 may be composed of a cylindrical top arranged transversely (along the width direction of the track) and a square platform-shaped bottom.
[0027] In one embodiment, the auxiliary guide rails 14 on the two side wings 13 extend forward / backward respectively, so that the auxiliary guide rails 14 form a staggered structure.
[0028] The staggered secondary guide rails 14 are designed so that during the operation of the crawler, whether it is subjected to lateral bending force or longitudinal tensile force, the secondary guide rails 14 between adjacent core metals 1 can support and limit each other, forming a stable mechanical closed loop. This closed loop structure can effectively disperse and resist external forces, avoiding deformation or damage of the crawler caused by local stress concentration.
[0029] In addition, the staggered layout of the auxiliary guide rails 14 increases the structural rigidity of the track in the lateral and longitudinal directions. When turning, the lateral bending force on the track can be more effectively dispersed and borne, reducing the deformation of the track caused by bending; similarly, when longitudinally stretched, the staggered auxiliary guide rails 14 can be tightly connected like a chain, enhancing the tensile strength of the track.
[0030] In addition, since the track is not easily deformed when subjected to force, it can maintain a more stable driving posture, reduce vehicle shaking or loss of control caused by track deformation, and thus improve the running stability and safety of the vehicle. Compared with traditional rubber tracks, it also has better shock absorption and noise reduction performance. It has good consistency in power transmission, can effectively reduce vibration intensity when subjected to impact force, and provide drivers and passengers with a more comfortable riding experience.
[0031] Finally, by enhancing the deformation resistance and overall structural strength of the track, the wear and damage of the track under harsh working conditions are reduced, the service life of the track is significantly extended, and the use cost and maintenance frequency are reduced.
[0032] In summary, the staggered auxiliary guide rail 14 design of this embodiment achieves high-strength lateral and longitudinal positioning of the crawler track through a clever mechanical structure layout, thereby ensuring the stability and safety of the crawler track under various complex working conditions.
[0033] In one embodiment, a first reinforcing rib 15 is provided between the auxiliary guide rail 14 and the guide protrusion 12 ; and a second reinforcing rib 16 is provided between the auxiliary guide rail 14 and the tooth wing 13 .
[0034] The first reinforcing rib 15 directly connects the guide protrusion 12 and the auxiliary guide rail 14 to form a more solid support structure. During the running of the crawler, the guide protrusion 12 needs to withstand the impact and lateral force from the ground to keep the crawler correctly guided. The addition of the first reinforcing rib 15 effectively disperses these forces, preventing the guide protrusion 12 from being deformed or damaged due to excessive force, thereby ensuring the guiding accuracy and stability of the crawler.
[0035] The auxiliary guide rail 14 is an important component of the crawler structure, and its strength is directly related to whether the crawler can remain intact and stable under harsh working conditions. The second reinforcing rib 16 is provided to tightly connect the auxiliary guide rail 14 and the tooth wing 13 together to form a more solid whole. In this way, when the crawler is subjected to longitudinal stretching or lateral bending, the second reinforcing rib 16 can absorb and disperse part of the stress, reduce the burden on the auxiliary guide rail 14, and prevent it from breaking or deforming due to excessive force.
[0036] The synergistic effect of the first reinforcing rib 15 and the second reinforcing rib 16 not only enhances the local strength of the guide protrusion 12 and the auxiliary guide rail 14, but also improves the overall rigidity and stability of the entire track structure. This double-reinforced design enables the track to maintain better passability and durability when dealing with complex terrain and harsh working conditions, thereby extending the service life of the track and reducing maintenance costs. The setting of the reinforcing ribs also helps to optimize the stress distribution of the track during the force-bearing process and reduce local wear and damage caused by stress concentration. This can not only improve the reliability and safety of the track, but also further reduce the frequency of maintenance and replacement during use.
[0037] In this embodiment, by providing the first reinforcing rib 15 and the second reinforcing rib 16, the rigidity and overall strength of the guide protrusion 12 and the auxiliary guide rail 14 are significantly improved, providing a strong guarantee for the stable operation of the crawler track under complex working conditions.
[0038] In one embodiment, rubber reinforcement ribs 21 protruding upward are provided on both sides of the rubber layer 2. The presence of the rubber reinforcement ribs 21 enables the track to maintain better structural stability when dealing with sudden impacts or heavy loads. The raised design of the reinforcement ribs increases the thickness and rigidity of the rubber layer 2, thereby improving the track's resistance to impact forces. This design is particularly suitable for application scenarios that require frequent handling of harsh working conditions or heavy-load transportation. In addition, the rubber reinforcement ribs 21 can not only directly enhance the rigidity of the track, but also optimize the stress distribution of the track during the force-bearing process. When the track is subjected to external force, the reinforcement ribs can guide the stress to be transmitted along a more reasonable path to avoid local damage caused by stress concentration. This stress dispersion effect helps to extend the service life of the track and reduce the frequency of replacement due to local wear or damage.
[0039] In addition, the rubber reinforcement ribs 21 and other structures of the crawler (such as the toothed wings 13, the auxiliary guide rails 14, etc.) work together to improve the overall performance of the crawler. The reinforcement effect of the reinforcement ribs complements the design of other structures, so that the crawler can show better anti-deformation ability and stability when dealing with various complex working conditions.
[0040] In one embodiment, an X-shaped slit 22 is provided on the rubber layer 2 between two adjacent bridges 11. Figure 1 As shown, by ingeniously setting an X-shaped slit 22 on the rubber layer 2 between two adjacent bridges 11, the running stability and durability of the crawler track in complex environments are greatly improved. Specifically, a series of problems that may be caused by foreign objects such as gravel or sand falling into the meshing space between the drive wheel and the crawler track (i.e., the area between the bridges 11) are effectively solved, such as affecting the normal meshing transmission, damaging the crawler track or the drive wheel, etc.
[0041] First, the setting of the X-shaped slit 22 provides a downward discharge channel for the gravel or sand that falls into the area between the bridges 11. When the track is running, these foreign objects will be discharged downward and outward along the X-shaped slit 22 under the action of gravity and the movement of the track itself. This mechanism effectively avoids the accumulation of foreign objects in the meshing space, thereby ensuring the normal meshing transmission between the drive wheel and the track. And because the rubber layer 2 has a certain elasticity and deformability, this allows the X-shaped slit 22 to maintain its shape while also being able to adjust to a certain extent according to the shape and size of the foreign object. This flexibility ensures that foreign objects can be discharged smoothly from the slit without being stuck due to mismatched slit sizes.
[0042] By timely expelling foreign matter, the design effectively prevents gravel or sand from damaging the track or drive wheel when the drive wheel and the track are engaged. The presence of foreign matter during the engagement process often leads to increased local pressure and may even scratch or wear the surface of the track and drive wheel. The expelling function of the X-shaped slit 22 greatly reduces the risk of such damage.
[0043] The timely removal of foreign matter ensures good contact and stable transmission between the drive wheel and the track, which helps improve the vehicle's driving stability and passability in complex terrain and reduces vehicle shaking or stagnation caused by foreign matter interference.
[0044] In one embodiment, the core gold 1 is phosphated. Phosphating can form a dense phosphate conversion film on the surface of the core gold 1, which has good corrosion resistance. It can effectively isolate the core gold 1 from direct contact with corrosive media (such as moisture, oxygen, acid and alkali, etc.), thereby extending the service life of the core gold 1 and reducing performance degradation or damage caused by corrosion. In addition, the surface of the core gold 1 that has been phosphated has improved roughness and microstructure, increasing the contact area and bonding force with subsequent coatings (such as rubber layer 2). This enhanced adhesion helps to improve the stability and durability of the overall structure and prevent the coating from falling off or peeling off. This greatly extends the service life and maintenance cycle of the track and reduces maintenance costs.
[0045] In one embodiment, the method for preparing the rubber layer material comprises the following steps: S1. Premixing treatment: placing butyl rubber or ethylene propylene rubber and a mixed solvent in a mass ratio component in an internal mixer for internal mixing treatment.
[0046] The specific steps are as follows: put the precisely proportioned butyl rubber or ethylene propylene rubber, together with the solvent mixed by ethyl acetate, methanol and acetone, into the internal mixer for meticulous internal mixing. The amount of solvent added must be just right to ensure that the two rubbers can be fully fused. During the internal mixing process, the feeding pressure roller is kept for 185-190 seconds, then the pressure roller is lifted and kept for 240-250 seconds, and then the temperature is raised to 142-148℃ before the rubber is discharged. Next, the rubber is transferred to the open mill, the roller spacing is adjusted to 7.2-7.8 mm, and after uniform rolling with a wrapping roller, cutting with a knife, and tamping 4-5 times, it is rolled. Finally, the roller spacing is fine-tuned to 0.8-1 mm, and a thin triangle package is processed, and it is left to stand for 6-48 hours to obtain a cut-resistant premixed rubber.
[0047] S2, a first stage mixing; the premix obtained in S1 and the components of the mass ratio of graphite powder / nano carbon black, phenolic resin / epoxy resin, nano calcium silicate / nano alumina are placed in an internal mixer for mixing.
[0048] The specific steps are as follows: put the premixed rubber into the internal mixer together with graphite powder / nano carbon black, phenolic resin / epoxy resin and special nano calcium silicate / nano alumina. During the internal mixing process, the charging pressure roller is kept for 205-210 seconds, and after the pressure roller is lifted and cleaned, the pressure roller is lifted again and kept for 115-125 seconds, and then the temperature is raised to 160-170℃ to discharge the rubber. Transfer to the open mill, adjust the roller distance to 8.5-9.5 mm, and after uniform rolling, cutting, and tamping 5-6 times, the sheet is produced and left to stand for 6-48 hours to obtain a mixed rubber compound.
[0049] S3, two-stage mixing: the rubber compound obtained in S2 and the activator of the mass ratio component are mixed and placed in an internal mixer for mixing.
[0050] The specific steps are as follows: After mixing the first-stage mixed rubber with the activator (specifically zinc oxide, stearic acid or silane coupling agent, etc.), put it into the internal mixer for internal mixing again. Keep the pressure roller for 175-185 seconds, lift the pressure roller and keep it for 45-55 seconds, then lift the pressure roller again, and then heat it to 148-152℃ to discharge the rubber. Transfer it to the open mixer, adjust the roller distance to 8.5-9.5 mm, and after uniform rolling, cutting, and tamping 2-3 times, the sheet is produced and left to stand for 6-48 hours to obtain the second-stage mixed rubber.
[0051] S4, refining; mixing the rubber compound obtained in S3 with sulfur and accelerator in a certain mass ratio and placing them in an internal mixer for internal mixing.
[0052] The specific steps are as follows: after mixing the second-stage mixed rubber with the oxide vulcanizer / resin vulcanizer and accelerator, put it into the internal mixer for refining. Keep the pressure roller for 85-90 seconds after adding materials, lift the pressure roller and keep it for 6-7 seconds, then press the pressure roller and keep it for 55-60 seconds, lift the pressure roller again and heat it to 100-105℃ to discharge the rubber. Transfer it to the open mill, adjust the roller distance to 5.5-6.5 mm, and after uniform rolling, cutting and tamping 2-3 times, take out the sheet and let it stand for 6-48 hours to obtain the wear-resistant and cut-resistant rubber composition.
[0053] S5, flat plate vulcanization: placing the refining rubber, core gold and cord prepared in S4 in a flat plate vulcanizer device for vulcanization treatment.
[0054] The specific steps are as follows: put the refining rubber, core gold, cord, etc. into a flat vulcanizer, and vulcanize them for 45-75 minutes at a temperature of 145-155°C under a pressure of 7-18MPa. After the vulcanization is completed, a wear-resistant and cut-resistant rubber track can be obtained.
[0055] During the entire preparation process, the rotor speed of the internal mixer was controlled at 32-42r / min, the pressure was maintained at 0.5-0.7MPa, and the initial temperature of the internal mixer was set at 57-63°C. The front and rear roller speed ratio of the open mixer was adjusted to 1:1.20, the front roller linear speed was controlled at 28-29m / min, the front roller temperature was maintained at 57-63°C, and the rear roller temperature was controlled at 52-58°C.
[0056] The rubber layer made by the above method uses carefully selected butyl rubber or EPDM as the base material, and after multiple mixing and refining processes, graphite powder / nano carbon black and other wear-resistant additives are added, which significantly improves the wear resistance of the rubber layer. This enables the rubber layer to resist external friction and wear during use and prolong its service life. In the preparation process, the rubber layer is effectively enhanced in cutting resistance through specific mixing and open mixing processes, as well as the addition of reinforcing agents such as nano calcium silicate / nano alumina. This enables the rubber layer to maintain good integrity when facing sharp objects or cutting forces, reducing the risk of breakage and fracture. In addition, the addition of phenolic resin / epoxy resin, as well as the fine control during multiple mixing and refining processes, gives the rubber layer excellent mechanical properties such as tensile strength, tear strength and hardness. This ensures that the rubber layer can withstand large stress and deformation during use and maintain stable performance.
[0057] In summary, the rubber layer made by the above method has excellent wear resistance, cutting resistance and good mechanical properties, thereby greatly improving the service life of the track. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
