[0001] Related applications

[0002] The present application claims priority to Chinese Patent Application No. 202411036839.0, filed on July 30, 2024, and incorporates by reference the entire disclosure of the aforementioned patent application as part of the present application. TECHNICAL FIELD

[0003] The present disclosure relates to the technical field of crawlers, in particular to a crawler structure for realizing single-track steering function. BACKGROUND

[0004] According to the characteristics of the crawler, the crawler vehicle has the advantages of high passability and strong load capacity, and is widely used in agricultural machinery, engineering vehicles and military vehicles. At present, most crawler vehicles are provided with two or more than two crawlers, and the steering effect is realized by differential rotation or opposite direction rotation of the two crawlers. Due to the limitation of the double-crawler steering principle, the double-crawler vehicle must be installed with two or more than two crawlers, which leads to the fact that the width of the crawler vehicle is inevitably affected by the number and width of the crawlers, that is, the width of the vehicle is greater than or equal to the width of the two crawlers. At the same time, because the vehicle steering must be realized by the rotation of the two crawlers at different speeds and in different directions, it is required that the crawler vehicle must rely on a coaxial and opposite transmission mechanism or a similar complex steering mechanism, which increases the structural complexity of the crawler vehicle.

[0043] In one track unit 10, the middle connector 2, the first pin shaft 3 and the middle pin ear 7 are independent of each other, as shown in FIGS. 1 and 2. Alternatively, the middle connector 2 and the first pin shaft 3 are connected as a whole (i.e. integrated structure), and the first pin shaft 3 is detachably connected with the middle pin ear 7. Alternatively, the middle pin ear 7 and the first pin shaft 3 (and the track shoe 1) are connected as a whole (i.e. integrated structure), and the first pin shaft 3 is detachably connected with the middle connector 2.

[0046] A vehicle is introduced below, as shown in FIG. 1 to FIG. 5, the vehicle contains a frame 11 and a front fork 15 and a steering handle 12 connected in turn, the front fork 15 is connected with the frame 11 through the shaft connecting ear 13, the vehicle also contains only one of the above-mentioned track structure capable of realizing single-track steering function (also can be called track capable of realizing single-track steering), the wheel 14 is connected with the track structure capable of realizing single-track steering function, and the wheel 14 can drive the track structure capable of realizing single-track steering function to walk and steer.

[0047] Along the circumference of the wheel 14, the outer circumferential surface of the wheel 14 contains the first outer large diameter section 1401, the second middle large diameter section 1402, the intermediate small diameter section 1403, the second middle large diameter section 1402 and the first outer large diameter section 1401 connected in turn.

The intermediate small diameter section 1403 can abut against the upper surface of the supporting block 6.

[0049] As shown in FIG. 3 to FIG. 5, the matching and plugging of the first plug-in grooves 1404 with the outer side section 502 is similar to the gear meshing connection, and the matching and plugging of the first plug-in grooves 1404 with the outer side section 502 can prevent the wheel 14 from being separated from the track structure capable of realizing single-track steering function. The matching and plugging of the second middle large diameter section 1402 with the guide tooth 8 is also similar to the gear meshing connection, which can better guide the matching and plugging of the first plug-in grooves 1404 with the outer side section 502.

[0050] When the wheel 14 rotates, the track structure with the single-track steering function can be driven forward by the wheel 14, and the wheel 14 can supply power to the track structure with the single-track steering function. When steering is needed, the handlebar 12 drives the fork 15 and the wheel 14 to swing left or right, and the track plates 1 of the two adjacent track units 10 below the fork 15 can be correspondingly rotated around the first pin shaft 3 of the rear track unit 10, so as to realize the steering function of the track structure with the single-track steering function.

[0051] By applying the track structure with the single-track steering function of the embodiment of the present disclosure to the track motorcycle, the wheel type and ski steering structure in the related art can be removed, and a steering device in the form of a motorcycle handlebar can be used. By twisting the handlebar 12, the vehicle can be guided to turn, and thus, since the driver sits on the rear seat of the motorcycle and most of the weight is borne by the rear bearing wheel, the vehicle will not be subjected to great turning resistance when the handlebar is twisted to guide the vehicle to turn. In order to optimize the turning performance of the vehicle, a guide wheel for assisting steering can be additionally arranged in the middle of the vehicle to improve the steering efficiency. Since the track structure is used throughout the vehicle, there is no additional wheel type and ski steering mechanism, the maintenance cost and difficulty of the track vehicle are reduced, the passability of the vehicle on various roads is improved, and the motorcycle vehicle originally designed with two tracks can be converted by changing the tracks from being arranged on both sides to being arranged in the middle below the vehicle, so as to reduce the width of the vehicle and improve the passing ability of the vehicle on narrow roads.

[0052] The above is only a specific embodiment of the present disclosure, and cannot be used to limit the scope of the present disclosure. Therefore, the replacement of equivalent components or equivalent changes and modifications made within the scope of the present disclosure should still be within the scope of the present patent. In addition, the technical features in the present disclosure can be freely combined with each other, and the technical features can be freely combined with each other.
