[0027] A combined tire includes two side wheels 1 and a connection assembly 2. The connection assembly 2 includes a plurality of mutually independent tooth plates 21; the side wheel 1 includes a first tire body, in which a first support body is arranged; the first support body includes a first rim 14, in which a first connecting plate 11, a first hub 12 and a plurality of first spokes 13 arranged circumferentially on the surface of the first hub 12 are arranged; the first connecting plate 11 is located on one side of the plurality of first spokes 13; preferably, the sum of the widths of the first connecting plate 11 and the first spokes 13 is equal to the width of the first rim 14; a plurality of slots 111 are arranged circumferentially on the side of the surface of the first connecting plate 11 away from the first spokes 13; the first connecting plate 11 is also provided with a plurality of first bolt holes 112, such as Figure 4 shown.

[0028] During installation, the two side wheels 1 are arranged opposite to each other, and the two sides of the plurality of 21 teeth are respectively plugged into the slots 111 on the first connecting plates 11 of the two side wheels 1. The connecting bolts 4 are passed through the first bolt holes 112 on the two first connecting plates 11, and then the two side wheels 1 are fastened together by the nuts 5. Figure 1 shown.

[0029] It is worth noting that the width of the tooth piece 21 in Embodiment 1 is equal to the sum of the depths of the slots 11 of the two side wheels 1, which can well hide the tooth piece 21 and increase the tire width.

[0030] Embodiment 2:

[0031] Different from the first embodiment, in the present embodiment, an intermediate wheel 3 is further provided between the two side wheels 1; wherein the intermediate wheel 3 comprises a second tire body, a second support body is provided in the second tire body, and the second support body comprises a second rim 34; a second hub 33 and a plurality of second spokes 31 circumferentially provided on the surface of the second hub 33 are provided in the second rim 34; a second connecting plate 32 is provided between two adjacent second spokes 31; preferably, a through groove 321 is provided on the second connecting plate 32 at a position corresponding to the slot 111 of the first connecting plate 11; a second bolt hole 322 is provided on the second connecting plate 32 at a position corresponding to the first bolt hole 112 of the first connecting plate 11, as shown in FIG. Figure 5 shown.

[0032] During installation, the two side wheels 1 are arranged opposite to each other, and the middle wheel 3 is placed between the two side wheels 1; first, each tooth piece 21 is inserted into the through slot 321 on the second connecting plate 32 in sequence, and then the parts of the tooth piece 21 extending out of the through slot 321 on both sides are respectively plugged into the slots 111 of the two side wheels 1, and finally, the connecting bolt 4 is passed through the first bolt hole 112 and the second bolt hole 322, and then the two side wheels 1 and the middle wheel 3 are fastened together by the nut 5. Figure 2 shown.

[0033] It is worth noting that the width of the tooth piece 21 in the second embodiment is equal to the sum of the depth of the slots 111 of the two side wheels 1 and the width of the second rim 34, thereby well hiding the tooth piece 21 and increasing the tire width.

[0034] Embodiment 3:

[0035] Based on the structure of Example 1, this embodiment adds an axle seat 22 coaxial with the first hubs 12 of the two side wheels 1 to the connecting component 2; wherein, a plurality of slots are arranged at equal intervals along the circumferential direction on the surface of the axle seat 22 for plugging in a plurality of gear pieces 21; and a groove matching the two ends of the axle seat 22 is added in the middle of the first connecting plate 11.

Figure 3 shown.

[0037] However, it is worth noting that the width of the tooth piece 21 in Example 3 is greater than the sum of the depths of the slots 111 of the two side wheels 1. After installation, a portion of each tooth piece 21 is exposed between the two side wheels 1. This increases the width of the tire while forming a blade-shaped fin structure to increase grip. This embodiment is mainly used in outdoor sandy land, uneven construction sites, mountains or grasslands, etc., to improve the overall stability of the vehicle body.

[0038] Further preferably, anti-skid treads are provided on the outer surfaces of the first tire body and the second tire body.

[0039] The utility model can realize three combination forms, namely, a two-wheel combination type, a three-wheel combination type and a two-wheel exposed gear type, through connecting components. It has a simple structure and is convenient for installation and disassembly. By increasing the tire width, the tire stability is improved and the problem of insufficient tire grip on uneven outdoor terrain can be solved, thereby effectively improving the overall balance performance and carrying capacity of the vehicle body.
