Among them, the wheel 200 may be the traveling wheel 303 of the bogie 300, which functions to support the bogie 300 and drive the bogie 300; the wheel 200 may also be the guide wheel 3041 of the bogie 300, which provides driving guidance for the bogie. The wheel 200 can also be the stabilizing wheel 3042 of the bogie 300, which provides the function of providing lateral stability to the bogie 300 and preventing rollover; of course, the wheel 200 can also be other wheels, such as automobile wheels. Among them, the guide wheel 3041 and the stabilizer wheel 3042 each belong to a type of the horizontal wheel 304.

如图1-6所示，根据本公开实施例提供的安全轮100，包括至少两个单体10和连接件2。As shown in FIGS. 1-6, a safety wheel 100 provided according to an embodiment of the present disclosure includes at least two cells 10 and a connecting member 2.

如图1-8所示，多个单体10大体为圆弧形结构，且多个单体10依次连接，形成圆环形结构，即安全轮100大体为圆环形结构。As shown in FIG. 1-8, the multiple monomers 10 are generally arc-shaped structures, and the multiple monomers 10 are sequentially connected to form a circular ring structure, that is, the safety wheel 100 is generally a circular ring structure.

安全轮100的旋转轴的延伸方向为轴向，即附图中的x轴延伸方向，其中x轴正方向为前，x轴负方向为后。过安全轮100的圆心且垂直于轴向的面为圆周面。在圆周面上，以安全轮100的圆心为起点向外直线延伸的方向为径向，其中靠近安全轮100的圆心的方向为内，远离安全轮100的圆心的方向为外。在圆周面上，绕安全轮100的圆心旋转的方向为周向，即附图中的w方向，其中w正方向为顺时针方向，w负方向为逆时针方向。The extension direction of the rotation axis of the safety wheel 100 is the axial direction, that is, the x-axis extension direction in the drawing, wherein the positive direction of the x-axis is forward and the negative direction of the x-axis is rear. A surface passing through the center of the safety wheel 100 and perpendicular to the axial direction is a circumferential surface. On the circumferential surface, a direction extending straight outward from the center of the safety wheel 100 as a starting point is radial, wherein the direction near the center of the safety wheel 100 is inward and the direction away from the center of the safety wheel 100 is outward. On the circumferential surface, the direction of rotation around the center of the safety wheel 100 is the circumferential direction, that is, the w direction in the drawing, where the positive direction of w is clockwise and the negative direction of w is counterclockwise.

The single body 10 has a front-to-back symmetrical structure, so the safety wheel 100 does not affect the function of the safety wheel 100 after the safety wheel 100 is flipped relative to the circumferential surface. The trailing end 10b is the original leading end 10a.

When inflating the tire 5, the gas enters through the second vent hole 43 and the first vent hole 32, passes through the gap between the cushion washer 3 and the cell 10, and then enters the tire 5 through the gap between the plurality of cells 10. To complete the inflation.

在一些实施例中，缓冲垫圈3的内表面3b为旋转面。如图4-5所示，缓冲垫圈3 的内表面3b的母线为曲线或折线。缓冲垫圈3适于套装在轮辋4上，且适于与轮辋4过盈配合，则缓冲垫圈3的内表面3b将受压变形。因此，缓冲垫圈3的内表面3b的母线为曲线或折线时，缓冲垫圈3与轮辋4的接触更加紧密。In some embodiments, the inner surface 3b of the buffer washer 3 is a rotating surface. As shown in Fig. 4-5, the generatrix of the inner surface 3b of the buffer washer 3 is a curve or a polyline. The buffer washer 3 is suitable for being fitted on the rim 4 and is suitable for interference fit with the rim 4, so that the inner surface 3 b of the buffer washer 3 will be deformed under pressure.
