Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of crawler track structures, and particularly relates to an X-shaped anti-skid and durable double-pin crawler track structure. Background Art
[0002] Track structures not only play an important role in the military field, but are also widely used in agriculture, construction and other fields. As a key component in engineering machinery and military equipment, there are indeed some challenges and problems in the design and use of tracks, mainly including the following aspects:
[0003] 1. Wear and tear: The track will rub against the ground during use, and long-term friction will cause the track to wear out. Especially when working in harsh environments, such as rocky, muddy or high-temperature environments, the wear rate will be faster.
[0004] 2. Adaptability limitations: Although tracks can provide good traction in complex terrain, they may still be difficult to adapt to certain special terrains (such as extremely rugged or soft land).
[0005] 3. Environmental impact: Tracks may cause damage to the ground during operation, especially in sensitive environments such as grasslands, wetlands or agricultural land.
[0006] There are currently two types of track shoes:
[0007] One is the metal single-pin track. Due to its structural characteristics, the contact area between the pin and the bushing is small, resulting in faster wear. Especially in harsh working environments, such as hard roads or terrains containing a lot of sharp gravel, the wear will be more serious. And because the single-pin track wears quickly, the pin and bushing need to be replaced frequently, which increases maintenance costs and downtime. Most single-pin tracks are integrally cast. Since the track pin has a large friction area and rotation angle during use, it wears quickly. When the pin ear wears more, the track length will increase. After exceeding a certain value, it cannot be used and has a short lifespan. In addition, the cast track has poor rigidity and is prone to bending and breaking. In addition, there are meshing holes on the track with a tooth meshing structure, which are easy to get stuck with foreign objects and the track is prone to falling off, so it is not suitable for use on high-speed vehicles.
[0008] The second is the metal double-pin track. The weight of the metal track is relatively heavy, which will increase the weight of the whole machine and increase energy consumption. In addition, the metal double-pin track is costly, heavy and less economical. The metal track will cause damage to the ground during operation. Utility Model Content
[0009] The purpose of the embodiment of the utility model is to provide an X-shaped non-slip and durable double-pin track structure, aiming to solve the problems of high cost and heavy weight of the existing track structure, as well as poor passability and damage to the ground when faced with terrain restrictions.
[0010] The utility model is implemented as follows: an X-shaped non-slip and durable double-pin crawler structure includes an induction tooth and a crawler section, and also includes: two pin shafts passing through the induction tooth, and bushings arranged at both ends of the crawler section; both ends of the two pin shafts are respectively connected to the crawler section through bushings, and the pin shafts pass through the bushings; the induction tooth is located in the middle of the road wheel, and both ends of the two pin shafts are fixedly connected through a locking device; a rectangular groove is arranged on the outer side of the crawler section, and an X-shaped grounding rib is arranged in the groove; an engaging hole is arranged on the inner side of the crawler section, and the crawler section is transmission-connected to the driving wheel through a plate hole engaging structure.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0029] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0030] like Figure 1-Figure 9As shown, an X-shaped non-slip and durable double-pin track structure provided by an embodiment of the utility model includes an induction tooth 1 and a track segment 6, and also includes: two pin shafts 5 passing through the induction tooth 1, and bushings 2 arranged at both ends of the track segment 6; both ends of the two pin shafts 5 are respectively connected to the track segment 6 through the bushings 2, and the pin shafts 5 pass through the bushings 2; the induction tooth 1 is located in the middle of the road wheel, and both ends of the two pin shafts 5 are fixedly connected by a locking device 4; a rectangular groove is arranged on the outer side of the track segment 6, and an x-shaped grounding rib 3 is arranged in the groove; an engagement hole is arranged on the inner side of the track segment 6, and the track segment 6 is transmission-connected to the driving wheel through a plate hole engagement structure.
[0031] In the embodiment of the utility model, through the above design, the four corners of an induction tooth 1 are connected to the track segment 6 through the bushing 2 and the pin 5, and each track segment 6 has two induction teeth 1 connected to the bushing 2 and the pin 5. The induction tooth 1 is located between the left and right track segments 6. The induction tooth 1 plays a role in adjusting the track segment 6 to prevent the track segment 6 from falling off when the vehicle turns and rolls. The driving wheel has a small pitch and a large number of teeth, which can make the track run smoother. The double-pin track is equipped with locking devices, such as locking nuts. These devices ensure that the position of the pin in the track is stable; the two ends of the x-shaped grounding rib are rounded. The x-shaped grounding rib 3 is based on the commonly used eight-shaped grounding rib in the current design, and is improved to an x-shaped grounding rib 3 here. The x-shape comes from the hourglass, and the upper and lower parts are triangles. The triangle has stability, which can not only increase the contact area between the track and the ground, but also improve the traction and stability of the vehicle.
[0032] like Figure 1 and Figure 8 As shown, as a preferred embodiment of the utility model, the induction tooth 1 is hollow and a locking nut 7 is provided on the induction tooth 1.
[0033] In the embodiment of the utility model, the induction tooth 1 is contracted inward by the cooperation of the bolt and the locking nut 7, so that the induction tooth 1 clamps the two pins 5 to prevent the pins 5 from shaking relative to the induction tooth 1.
[0034] like Figure 1 and Figure 8 As shown, as a preferred embodiment of the utility model, both sides of the top of the induction tooth 1 are chamfered, and the two sides of the top of the induction tooth 1 form a 45° angle, and the top of the induction tooth 1 is connected with a rounded corner.
[0035] like Figure 1-Figure 9 As shown, as a preferred embodiment of the utility model, the inner wall of the bushing 2 is provided with internal threads, both ends of the pin shaft 5 are provided with external threads, the locking device 4 is elliptical, and a bolt is penetrated and connected in the middle of the locking device 4.
[0036] In the embodiment of the utility model, the diameter of the external thread at both ends of the pin shaft 5 is 3.5 cm, so as to facilitate fixing and disassembly; the pin shaft 5 is responsible for connecting the track section 6, so that the track section 6 can circulate around the driving wheel and the idler wheel; the locking device 4 is located at both ends of the track system, that is, near the driving wheel and the idler wheel, and directly acts on the track to ensure that it maintains a proper tension state during the entire operation process. The track power source of the double pin track of this embodiment is mainly the driving wheel, which is connected to the engine through gears or belts. When the engine is running, the driving wheel rotates accordingly. The teeth on the driving wheel mesh with the teeth on the inner side of the track. When the driving wheel rotates, it drives the track chain to roll along the wheel, thereby pushing the vehicle forward or backward.
[0037] like Figure 1 As shown, as a preferred embodiment of the present utility model, the material of the track segment 6 is vulcanized rubber.
[0038] In the embodiment of the utility model, when making the double-pin crawler type, different materials are considered to have different effects: Traditional vulcanized rubber: rubber materials have good shock absorption performance, which can reduce noise and vibration during operation; the production cost of rubber crawlers is relatively low, and the maintenance and replacement costs are also low; rubber crawlers are lighter than metal crawlers, which helps to reduce the total weight of the vehicle and improve fuel efficiency and maneuverability. There are also disadvantages: the strength and bearing capacity of rubber crawlers are usually lower than those of metal crawlers, and they are not suitable for heavy machinery. Metal: Made of high-strength steel, it can withstand the high load and high impact of heavy machinery, but the metal crawler is heavier, which will increase the overall weight of the vehicle, affect fuel efficiency and maneuverability, and in terms of snow rescue operations, the metal crawler may generate large noise and vibration during operation, which will cause potential dangers, and the production cost is relatively high, and the maintenance and replacement costs are also high.
[0039] Comparison of double pin tracks of different materials
[0040]
[0041]
[0042] If a metal double-pin crawler is used, its cost is much higher than that of a traditional vulcanized rubber double-pin crawler, and it is not suitable for the snow rescue operation environment. Therefore, this embodiment adopts a traditional vulcanized rubber double-pin crawler.
[0043] like Figure 2-Figure 5 As shown, as a preferred embodiment of the utility model, the forward inclination angle of the crawler section 6 is 15 degrees.
[0044] In the embodiment of the utility model, in order to make the rescue work in the snow safer and more convenient, the track plate needs to adopt a forward inclination angle similar to that of a tank track. Figure 2As shown, the track segment 6 adopts a forward inclination angle of 15 degrees on the front side of the vehicle, which helps to increase the contact area between the track and the ground, thereby improving traction and making the vehicle more stable when driving on soft ground such as snow; the X-shaped ground ribs 3 are located outside the square concave surface of the track segment 6, and the two ends of the X-shaped ground ribs 3 are rounded, which can increase the contact area between the track and the ground, which is beneficial to improving the traction and adhesion between the track and the ground.
[0045] In order to ensure the convenience of snow rescue workers, this design minimizes the manual cleaning of track grooves. The double-pin type is easy and quick to clean, and there is no need to remove the entire piece like the single-pin type;
[0046] A plate hole meshing structure is adopted, and the plate hole meshing structure is located between the track shoe and the track pin. The previous slot design is removed and a meshing hole is used to match the driving wheel pitch to reduce the entry of foreign matter; the induction tooth is located at the connection between the front and rear track shoes and in the middle of the road wheel. The induction tooth is changed to a hollow structure to reduce weight while improving silt removal capacity; the traditional vulcanized rubber double-pin track has greatly enhanced anti-skid ability, reduced cost and long life, which is conducive to the operation of snow rescue vehicles.
[0047] This embodiment takes snow rescue as an example. Since the target track is on the snow, in actual scenarios, due to deep snow accumulation and poor road conditions, the snow becomes an ice surface under pressure. Ordinary single-pin tracks have fewer contact points and relatively weak traction, and are prone to slipping. In addition, the stability in the snow is poor, and the vehicle may easily lose control due to slipping of one side of the track. The single-pin track generates a lot of noise during operation, which may disturb wild animals or cause potential dangers such as avalanches, which will increase the risk of rescue operations.
[0048] At present, most snow rescue vehicles use double-pin tracks, which is also the most ideal and efficient snow rescue method. Double-pin tracks can not only provide the necessary traction and stability, but also simplify the maintenance and repair process and improve rescue efficiency. Based on this, this implementation case also adopts a double-pin track structure.
[0049] The above description is only a preferred embodiment of the present invention and is 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.
