Description

Technical Field

[0001] This utility model relates to the field of all-terrain vehicle technology, specifically to a combined high-speed track for a tracked all-terrain vehicle. Background Technology

[0002] Tracked all-terrain vehicles are tracked all-terrain engineering vehicles that can travel in various geographical environments such as high-altitude mountains, tropical jungles, deserts, swamps, rivers and lakes, and have high off-road passability, amphibious function, high flexibility and reliable protection capabilities. The vehicle has a maximum speed of ≥50km / h and is required to travel on paved roads. Currently, there are three main technical approaches on the market: First, ordinary metal tracks, which have a maximum speed of only 5-10km / h, are too slow to meet the road conditions and are prone to damaging the road surface when traveling on paved roads; second, integral rubber tracks, which require the design and development of large molds for integral molding and vulcanization, resulting in high costs and non-adjustable track length. When the track is damaged, the entire track needs to be replaced, leading to high maintenance costs. For example, a rubber track block with publication number CN117401051A and a detachable rubber track for vehicles, although detachable, still have high maintenance costs; third, tracks using rubber belts with metal track teeth, where the rubber belt is prone to breakage under impact, resulting in unstable quality. Rubber plates are also required when traveling on paved roads. For example, a widely applicable multi-terrain adaptable track with publication number CN111071359B includes an inner belt body made of stainless steel and an outer belt body made of rubber. The outer belt body is located outside the inner belt body, and the inner belt body includes several spliced ​​unit plates spliced ​​together in a strip shape. Summary of the Invention

[0003] The purpose of this invention is to provide a track with a metal link + rubber track plate structure, which can be flexibly adjusted according to the required track length, without the need for large molds for integral molding, resulting in low cost and reliable quality; the metal track links are connected by rubber-coated pins, ensuring reliable strength and preventing track breakage; the rubber layer of the rubber-coated pins pre-tightens the metal track links, meeting the requirements for high-speed driving; furthermore, when the rubber plate is damaged, only the damaged part needs to be replaced, without replacing the entire track, making maintenance convenient and cost-effective.

[0004] The technical solution of this utility model is: a combined high-speed track for tracked all-terrain vehicles, comprising multiple unit structures, with adjacent unit sections rotatably hinged together by a bracket pin, so that multiple unit structures are connected in series to form a closed-loop track; The unit structure includes rubber track plates, with metal rubber-coated track links connected to the upper end of the track plates via fastening devices. Each metal rubber-coated track link includes multiple mounting blocks connected in sequence, with horizontal pin holes on the side of each mounting block. The mounting blocks of adjacent metal rubber-coated track links are alternately inserted into each other, so that the pin holes on them are coaxially aligned, thereby forming a common connection channel for the bracket pin to pass through and achieve hinge connection.

[0005] Furthermore, the hanger pin includes a cylindrical metal pin; and a rubber layer tightly covering the outer circumferential surface of the metal pin. The rubber layer is composed of multiple coaxial cylindrical rubber segments arranged at intervals, with an annular gap formed between adjacent rubber segments.

[0006] Furthermore, the metal-coated track link includes a drive tooth and five sequentially connected mounting blocks, which are connected to the drive tooth and arranged in an alternating manner, such that the pin connection holes of the mounting blocks are located on both sides.

[0007] The first, third, and fifth mounting blocks have right-side pin connection holes on their right sides, and the second and fourth mounting blocks have left-side pin connection holes on their left sides. The upper surfaces of the first and fifth mounting blocks are provided with rubber track plate mounting holes; the upper surface of the third mounting block is provided with metal teeth; and the upper surfaces of the second and fourth mounting blocks are covered with a rubber layer.

[0008] Furthermore, the track plate has a boat-shaped structure with mounting holes.

[0009] Furthermore, the fastening device includes bolts, washers, and connecting nuts.

[0010] Furthermore, the metal rubber-coated track link is placed on the upper surface of the track plate, and the rubber track plate mounting hole of the metal rubber-coated track link is aligned with the mounting hole on the track plate. The bolt passes through and is fastened to the two by the cooperation of the washer and the connecting nut.

[0011] Furthermore, the drive teeth of the metal-coated track link mesh with the tooth grooves of the drive wheel II to achieve power transmission and ensure reliable drive of the track under high-speed conditions.

[0012] Furthermore, the rubber layer on the surface of the metal-coated track link cooperates with the rubber layer on the rim of the support roller III to buffer contact impact and reduce wear during high-speed operation; the metal teeth form a lateral limiting structure to constrain the lateral displacement of the support roller III and prevent the track from slipping off.

[0013] The beneficial effects of this utility model are: 1. This utility model meets the requirements for high-speed driving on paved roads while possessing high reliability. The core transmission chain consists of metal-coated rubber track links and bracket pins. This metal structure provides the high strength and tensile strength of traditional metal tracks, fundamentally solving the problems of pure rubber tracks being prone to breakage and unable to withstand high-speed, high-horsepower drives. The rubber layer of the bracket pins provides elastic cushioning and vibration damping at the hinges, absorbing the impact and noise generated during high-speed operation, making the ride smoother and meeting the stability requirements for high-speed driving. As the part in direct contact with the ground, the rubber track pads effectively protect the paved road surface from metal scratches while providing good grip and driving comfort.

[0014] 2. This utility model significantly reduces manufacturing and maintenance costs, and the length is flexibly adjustable. The entire track is composed of multiple independent metal-coated rubber track links connected in series by bracket pins, and finally fitted with individual rubber track plates. This eliminates the need for expensive, large-scale molds for integral rubber tracks of different lengths, greatly reducing production costs and barriers to entry. Users can flexibly combine tracks of the required length according to vehicle model and needs, just like assembling chains, offering strong versatility. When track plates are worn or damaged, the damaged track plate can be replaced individually simply by unscrewing the connector, without scrapping the entire expensive track, greatly reducing maintenance and lifecycle costs.

[0015] 3. This invention improves service life and operational stability while reducing wear on surrounding components. The rubber layer on the metal-coated track link engages with the rubber rim of the track roller, forming a soft contact that effectively reduces friction and wear between the metal and rubber, protecting the track link itself and extending the service life of the track roller. Metal teeth, acting as limiting teeth, engage with both sides of the track roller to prevent lateral track slippage during high-speed turns or tilts, ensuring operational safety and stability. The rigid meshing of the drive teeth with the drive wheel ensures efficient and reliable power transmission, preventing slippage, making it particularly suitable for high-speed, heavy-load conditions.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0019] Example 1: Refer to Figure 1 The metal-coated rubber track link 3 is the core load-bearing and transmission component in the composite track. Its structure includes a drive tooth 3-1, a left-side pin connection hole 3-2, a rubber layer 3-3, a metal tooth 3-4, a rubber track plate mounting hole 3-5, and a right-side pin connection hole 3-6. This link uses a staggered arrangement of multiple mounting blocks. The first, third, and fifth mounting blocks have right-side pin connection holes 3-6 on their right sides, while the second and fourth mounting blocks have left-side pin connection holes 3-2 on their left sides. The third mounting block has a metal tooth 3-4 at its upper end for lateral restraint; the second and fourth mounting blocks are covered with a rubber layer 3-3 for cushioning and wear reduction; and the first and fifth mounting blocks have rubber track plate mounting holes 3-5 at their upper ends for mounting track plates 2. This link is hinged to adjacent links via a bracket pin 1, forming a reliable and flexible chain structure. Its drive tooth 3-1 can mesh with the drive wheel II, effectively transmitting power and ensuring driving performance at high speeds.

[0020] Example 2: Refer to Figures 2-4 The track link unit is assembled from a metal rubber-coated track link 3, a bracket pin 1, and rubber track plates 2. The bracket pin 1 consists of a metal pin 1-2 and multiple spaced-apart cylindrical rubber segments 1-1, as shown in the diagram. Figure 4During assembly, the bracket pin 1 is pressed into the aligned pin holes (left pin connection hole 3-2 and right pin connection hole 3-6) of two adjacent chain links after alternating insertion. The connection is secured and vibration-damping thanks to the interference fit between the rubber layer 1-1 and the hole wall. The track plate 2 is a boat-shaped rubber plate, fixed to the rubber track plate mounting hole 3-5 at the upper end of the metal-coated rubber track link 3 by connecting bolts 4, washers 5, and connecting nuts 6. This structure protects the paved road surface and facilitates individual replacement of the track plate 2 after wear, significantly reducing maintenance costs.

[0021] Multiple track link units are hinged end to end by the bracket pin 1 to form a track chain of any length. No integral mold is required, resulting in low manufacturing cost and strong adaptability.

[0022] Example 3: Refer to Figure 5 The combined track system, working in conjunction with the drive wheel II and track roller III, utilizes track I and the drive wheel II. Specifically, the drive teeth 3-1 of the metal-coated track link 3 mesh correctly with the tooth grooves of the drive wheel II, achieving efficient power transmission and meeting the requirements of high-speed travel on paved roads. The rubber layer 3-3 on the upper surface of the track link contacts the rubber layer on the rim of the track roller III, effectively buffering vibration and reducing wear and noise during high-speed operation. The metal teeth 3-4 are located on both sides of the track roller III, forming lateral restraint and preventing the track from slipping off during turning or tilting. This track system combines the strength of a metal structure with the elasticity of rubber materials, resulting in high overall reliability and a long service life, making it particularly suitable for the high-speed, multi-condition use requirements of all-terrain vehicles.

[0023] This utility model presents a combined track system of metal track links and rubber track plates, preventing high-speed tracks from damaging paved roads. Depending on the track length requirements, metal track links 3 are connected by bracket pins 1 to form a single chain, which is then fitted with rubber track plates 2 to create a high-speed rubber track. When the rubber track plates 2 wear out, only the damaged ones need to be replaced, thus meeting the requirements for high-speed travel on paved roads for tracked all-terrain vehicles. While meeting the high-speed travel requirements on paved roads, this design also addresses the issues of high track manufacturing and maintenance costs, and unreliable quality.

[0024] The above provides a detailed description of the combined high-speed track for a tracked all-terrain vehicle provided by this utility model. Specific examples have been used to illustrate the structure and working principle of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.
