[0031] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0032] Wheeled vehicles have poor passability on complex or soft roads, which limits their all-round combat capability. This embodiment proposes a lightweight wheel track for a special vehicle, which can be assembled on the front and rear tires when needed to increase the ground contact area between the vehicle and the ground and improve the all-round passability of the vehicle.

[0033] like Figure 1 As shown, the special vehicle lightweight wheel track includes a short track segment 1, a long track segment 2 and an inter-segment connection structure 3. Figure 2 As shown, the lightweight wheel track of the special vehicle is integrally mounted on the tire, which can better wrap the tire and improve the vehicle's passability on soft roads.

[0034] The short track segment 1 and the long track segment 2 have the same structure. The long track segment 2 in this embodiment is one track pitch longer than the short track segment 1. Through different combinations of the long track segment 2 and the short track segment 1, tracks with different loop lengths can be assembled.

[0035] like Figure 3As shown, the track segment is composed of a number of core metals, a colloid and two track pins 4. Among them, the two track pins 4 are located at the front and rear ends of the track segment, and a number of core metals are distributed between the two track pins 4. The core metals and the track pins 4 are vulcanized on the colloid. The distance between adjacent core metals is the track pitch. The colloid adopts a multi-layer composite rubber material, which has strong wear resistance and tear resistance.

[0036] like Figure 4 As shown, the core metal is formed of carbon fiber composite material, the bottom is a flat surface for supporting the tire, and the two ends are wrapped with curved surfaces that limit the tire. The overall structure is a C-shaped structure, which can improve the lateral and longitudinal stiffness of the track segment.

[0037] The track pin 4 is formed by plying carbon fiber composite materials, and a plane portion for limiting the position is provided at both ends. Figure 5 shown.

[0038] like Figure 6 As shown, the inter-segment connection structure 3 is located between two track segments and is used to connect two adjacent track segments. Figure 7 and 8 As shown, the inter-segment connection structure 3 includes an end coupler 5, a stopper 6 and a middle coupler assembly. The end coupler 5 is designed to be contoured, which can better wrap the tire and limit the tire to prevent the tire from falling off the track when the vehicle is moving. Fig. 9 As shown, the end coupler 5 includes an end coupler carbon fiber skeleton 5-1 and an end coupler colloid 5-2, and the end coupler colloid 5-2 is vulcanized on the end coupler carbon fiber skeleton 5-1. The end coupler 5 and the limit block 6 are assembled at both ends of the track pin 4. The limit block 6 is made of high-strength steel and is installed between the bottom pin holes of the end coupler 5. The two ends of the two track pins 4 are respectively inserted into the two bottom pin holes of the two end couplers 5, and the flat part on the track pin 4 fits with the side inclined surface of the limit block 6 to play a limiting role.

[0039] The two middle coupling assemblies are assembled in the middle section of the track pin 4 and are located between the two end couplings 5. Fig.10 and 11 As shown, each middle coupler assembly includes an upper middle coupler 7 and a lower middle coupler 8. The upper middle coupler 7 and the lower middle coupler 8 are butt-jointed, and both consist of a middle coupler carbon fiber skeleton 9-1 and a middle coupler colloid 9-2, and the middle coupler colloid 9-2 is vulcanized on the middle coupler carbon fiber skeleton 9-1.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
