[0026] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the scope protected by the utility model.

[0027] As shown in FIGS. 1-6 The utility model provides a kind of wheel of traditional cross-country pulley, including tire body 1, the tread 2 of tire body 1 is the arc structure of two ends low middle high;Tread 2 middle part is inwards recessed to form stable groove, to increase the sliding stability of wheel.

[0028] In the embodiment, tire body 1 is made of rubber material.

[0029] The wheel of traditional cross-country pulley provided by the utility model, by setting stable groove in the middle part of the tread 2 of tire body 1, can increase the sliding stability of traditional cross-country pulley, improve the simulation degree of simulating sliding real snow, and the wheel designed with M-shaped groove 3 can bring the improvement of product performance and experience when applied to traditional cross-country pulley product.

[0030] As an optional embodiment of the utility model, as shown in FIG. 1As shown, the stabilizing groove is an M-shaped groove 3 structure. The stabilizing groove is arranged along the whole circumference of the tread 2. By arranging the M-shaped groove 3, the whole tire body 1 can be regarded as two independent wheels, namely wheel A and wheel B, and since the M-shaped groove 3 is only inwardly recessed from the tread 2, the wheel A and the wheel B are still integrated and closely connected, so that when straight rolling is performed, the wheel A and the wheel B do not have a wheel speed difference, and the rolling directions of the wheel A and the wheel B are consistent, thereby ensuring the straight moving direction performance.

[0031] Further, the corner 4 of the M-shaped groove 3 is a sharp corner structure or a circular arc transition structure.

[0032] By arranging the M-shaped groove 3, in addition to the effect of improving stability, the M-shaped groove 3 can also prevent foreign matters such as stones on the road surface from being clamped into the groove.

[0033] Moreover, in order to further improve the foreign matter clamping prevention effect, the corner 4 of the M-shaped groove 3 can be arranged as a circular arc transition structure to prevent the corner 4 from clamping foreign matters.

[0034] In order to ensure stability during straight movement and prevent foreign matters from entering, the middle part of the M-shaped groove 3 is located inside the profile line of the tread 2 to form a gap 5 between the M-shaped groove 3 and the ground. The gap 5 allows the wheels to form two independent contact parts, reduces friction, improves drainage performance, ensures movement stability, and the middle clamping angle of the M-shaped groove 3 can prevent stones from entering and clamping foreign matters.

[0035] In an optional embodiment of the utility model, the middle clamping angle 6 of the M-shaped groove 3 is 90 degrees. Of course, other clamping angles can also be used, but the clamping angle is preferably greater than 60 degrees to prevent foreign matters from entering.

[0036] As another optional embodiment of the utility model, the stabilizing groove is a V-shaped groove structure.

[0037] When the V-shaped groove structure is used, although it can also improve stability, compared with the M-shaped groove 3, it has the problem of being easy to enter foreign matters such as stones, and the optimal embodiment is the M-shaped groove 3.

[0038] As a further improvement of the utility model, the corner 4 of the V-shaped groove is a sharp corner structure or a circular arc transition structure.

[0039] In order to reduce the clamping of foreign matters, a more suitable scheme is that the corner 4 is a circular arc transition structure.

[0040] In order to prevent foreign matter clamping, in this embodiment, the clamping angle of the V-shaped groove is an obtuse angle.

[0041] As a further improvement of the utility model, it also includes a hub installed on the tire body 1, and the hub is made of aluminum alloy.

[0042] The wheel of the traditional cross-country slide pulley has a groove in the middle of the tire, and the middle of the wheel has an M-shaped groove, so that the wheel can be regarded as two independent wheels, namely wheel A and wheel B.

[0043] The cross-country slide pulley comprises the wheel.

[0044] The wheel of the cross-country slide pulley is different from a conventional wheel in that the middle of the wheel has an M-shaped groove.

[0045] The wheel has an M-shaped groove in the middle, so that the wheel can be regarded as two independent wheels, namely wheel A and wheel B.

[0046] The M-shaped groove can destroy the water film on a wet and slippery road surface, and improve the drainage performance of the wheel.

[0047] The M-shaped groove can reduce the friction area between rubber and the ground, so as to increase the sliding speed and the influence of sand and stones on the wheel.

[0048] The M-shaped groove in the middle of the wheel can effectively prevent stones from being stuck in the groove, and reduce the influence of stones on sliding. FIG. 6 When the angle between the wheel and the ground is 60°, the wheel surface and the ground form the maximum friction, and can provide strong ground adhesion for the user when turning.
