Description

Technical Field

[0001] The utility model relates to the technical field of steel-based rubber crawlers, in particular to a high-speed lightweight steel-based rubber crawler. Background Art

[0002] The tracks that are widely used in the market are divided into three categories: pure rubber tracks, rubber-coated steel-based tracks, and pure steel-based tracks, each with its own advantages and disadvantages.

[0003] The advantages of pure rubber tracks are the material itself, which is light in weight, low in noise, and has good ductility. It can be used in light tracked vehicles with a curb weight of less than 800Kg. The disadvantage is that it has relatively high requirements for the use environment and load quality, and the speed cannot exceed 10Km / h, otherwise tearing, belt debonding, etc. will occur, and the overall safety of the vehicle cannot be guaranteed.

[0004] Rubber-coated steel-based crawler tracks, commonly known as engineering crawler tracks, have the advantages of a wide range of application environments, less restrictions on geographical and environmental conditions, a wider range of applications, no restrictions on loads, and different types of crawler tracks can be selected according to the equipment's curb weight; the disadvantage is that in actual use, the crawler itself is heavy. Considering factors such as application scenarios, the crawler speed design is not allowed to be higher than 15Km / h, otherwise there is a risk of the track coming off, which will cause unknown risks and safety hazards to the chassis;

[0005] The advantage of steel-based tracks is that they have a wide range of applications and are not restricted by geographical and environmental conditions. The disadvantage is that during actual use, the track itself has a large speed limit and the speed is very low. The track itself is heavy and will cause certain damage to the road during travel. It will generate a lot of noise, and friction will produce sparks and high temperatures, etc., and cannot be used in special industries and environments.

[0006] A Chinese patent (authorization announcement number CN 217753928 U, 2022.11.08) discloses an anti-derailment track iron tooth; its technical solution overcomes the technical defect of easy debonding between the iron tooth body and the rubber track by embedding the iron tooth body into the rubber track and pouring adhesive, but the meshing surface of the iron tooth body does not have a rubber coating, and directly contacts the driving wheel during work, and cannot overcome the problem of high operating noise; and its iron tooth body, reinforcement base plate and reinforcement angle plate are all solid structures, which increase the deadweight of the track and cannot be applied to high-speed design requirements; its structure using anti-slip teeth as driving teeth still has the problem of low driving bearing capacity, and cannot be applied to high-speed operation.

[0007] Therefore, how to provide a high-speed, lightweight steel-based rubber track that can combine the advantages of the above three types of tracks, achieve noise reduction while ensuring the structural compactness and high tensile strength of the track, and meet the speed design requirements equivalent to the running speed of armored tracks; improve adaptability to the traveling environment; and have good operating safety, stability, and maneuverability are problems that technical personnel in this field urgently need to solve.

[0069] The tooth steel base and track section of a high-speed lightweight steel-based rubber track provided in this embodiment are both plate structures, which have the structural characteristics of light weight; the anti-dropout tooth section 1111 formed by bending and the track section bottom plate 113 of the U-shaped bent plate structure both improve their own structural strength through the bending structure; the anti-dropout tooth section 1111 plays a role in preventing the track from dropping off; by setting an independent driving gear core 112 on the anti-dropout tooth section plate 111, the track can be suitable for high-speed driving to meet the design requirements of the running speed. Each tooth steel base component is fixed with a corresponding track section bottom plate 113, which enables the track to have the ability to operate in complex environments such as sand, mud, ice and snow, and can meet higher driving speed requirements.

[0071] In some embodiments, there are multiple driving gear cores 112 , and the multiple driving gear cores 112 are symmetrically arranged on both sides of the anti-dropout gear segment 1111 .

[0072] A plurality of driving shifting gear cores 112 are symmetrically arranged on both sides of the anti-slip gear segment 1111, which can improve the stability of the track driving force.

[0087] The utility model discloses a method for manufacturing a high-speed lightweight steel-based rubber crawler:

[0088] 1. Prepare anti-slip joint plates with the required number of track sections.

[0089] 2. Prepare a drive gear core with twice the number of required track sections.

[0090] 3. Place the drive gear core in the clamping grooves on both sides of the anti-dropout gear plate for positioning, and fix the drive gear core to both sides of the anti-dropout gear plate by spot welding. There should be no more than 6 welding points on each side, and the welding points should be full to form a gear system steel-based welded parts.

[0091] 4. Prepare wire rope sleeves with twice the number of required track sections.

[0092] 5. Prepare two steel ropes of the required track circumference length.

[0093] 6. Put the wire rope sleeve into the wire rope and evenly distribute it according to the track pitch; put the first and second ends of the wire rope into a wire rope sleeve together, use a press to press the wire rope sleeve to form a ring-shaped wire rope, and all sleeves are pressed and closed with the wire rope to form a combined steel cable.

[0095] 8. Prepare the track segment base plates with the required number of track segments.

[0096] 9. Prepare twice the number of hexagonal bolts, grade C, M5x175, thread length, 12mm, custom bolt shanks, and hexagonal nuts, grade A and grade B, M5.

[0097] 10.

[0101] Specifically, take the basic belt width of 200mm as an example. The anti-slip joint plate is made of frosted 304 stainless steel plate by stamping and bending. The stamped and bent part is 170mm long, 40mm wide, 63.5mm high and 2mm thick. It is stamped and formed in one time to ensure the overall structure is stable and the thickness is uniform; the anti-slip joint plate is the most important part of the overall structure. After being wrapped with rubber, it forms an independent tooth structure. During the high-speed operation of the crawler, it is always ensured that there are 2-3 anti-slip teeth in the middle of the load-bearing wheel to avoid the crawler from slipping due to high-speed transmission.

[0102] The driving gear core is stamped from frosted 304 stainless steel plate, formed in one step, with a material thickness of 2mm. It is installed on both sides of the anti-slipping gear plate and is spot welded to the anti-slipping gear plate as a whole. The single-side welding points are not more than 6 points; that is, the adjustment of the processing technology is simplified while increasing the structural strength of the anti-slipping gear plate. After the whole is covered with a rubber coating layer, a tooth-shaped structure is formed, which is used as a driving gear and an auxiliary anti-slipping gear.

[0103] The annular steel wire rope and the casing are used as the link structure. φ4 (7×7×0.1) steel wire rope is used and is evenly inserted into the steel wire rope casing according to the pitch size. The steel wire rope casing adopts a frosted 304 stainless steel C-type tube with an outer diameter of 6mm, an inner diameter of 4.2mm, and a length of 25mm. After the steel wire rope is evenly inserted, the C-type tube is pressed to close with a press machine, and is completely fastened to the steel wire rope; after the pressing is completed, the steel wire rope casing and the anti-slip tooth plate are welded according to the predetermined size, and the single-side welding points are not more than 6 points.

[0104] Track segment bottom plate and fastening bolts. The track segment bottom plate is the main load-bearing structure of the track. It is made of 2mm frosted 304 stainless steel plate by one-time stamping and bending to ensure the overall structure is stable and the thickness is uniform. After one-piece stamping, the dimensions are 166mm long, 38mm wide, and 29mm high. The two side ends are round tube sleeve structures with a trapezoidal groove in the middle. The connecting fixing bolts are hexagonal bolts C-grade M5x175 thread length 12mm custom bolts. The hexagonal head is bored and ground to make its surface rough with a roughness of 25Ra / um. The fixing bolts pass through the single-sided fixing through hole of the anti-slip gear plate and the single-sided sleeve structure of the track segment bottom plate. On the other side of the connecting end plate of the anti-slip gear plate, hexagonal nuts A-grade and B-grade M5 are used for fastening. The hexagonal head is bored and ground to make its surface rough with a roughness of 25Ra / um.

[0105] The steel wire layer and fiber fabric layer are laid between the track segment bottom plate and the anti-slip tooth segment plate after the internal steel base structure is connected and before the rubber coating is applied to increase the tensile and wear resistance of the track; 84 φ1 steel wires are used to ensure the radial force of the track. The fabric layer is made of Kevlar fiber cross-woven and can be symmetrically located on both sides of the steel wire and in contact with the track segment bottom plate and the anti-slip tooth segment plate.

[0106] After the above parts are arranged according to the size and layout requirements, they are placed in the mold and the rubber is poured; after the pouring is completed and cooled, the mold is removed and the track is completed.
