Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example 1

Referring to the attached drawings 1-2, the mechanical travelling wheel structure comprises a hub 1, a rim 2 and spokes 3, wherein the spokes 3 are radially connected between the hub 1 and the rim 2, the spokes 3 are rod-shaped or plate-shaped, the rim 2 is annular, a plurality of ground-pulling sheets 4 are uniformly arranged on the rim 2, the thickness of the ground-pulling sheets 4 is gradually increased from inside to outside in the radial direction of the rim 2, the thicker outer ends of the ground-pulling sheets 4 can increase friction and improve wear resistance when contacting with the ground, the ground-pulling sheets 4 are positioned on the outer end surfaces, in the radial direction, of the rim 2, of the outer ends of the ground-pulling sheets 4 protrude out of the outer end surface, in the radial direction, of the rim 2, the heights of the outer ends of the ground-pulling sheets 4 protruding out of the rim 2 are the same, namely, the radius of the top circumcircle of the ground-pulling sheets 4 is larger than the outer diameter of the rim 2, the ground-pulling sheets 4 are positioned on the inner end surfaces, in the radial direction, of the inner ends, the land scraping force during walking in the mud is improved, the land scraping sheets 4 are obliquely arranged in the rotating direction of the rim 2, the contact area is increased when the land scraping sheets 4 enter soil, the projection of the land scraping sheets 4 in the radial direction of the rim 2 is arc-shaped, after the land scraping sheets 4 rotate out of the soil, the arc-shaped land scraping sheets 4 facilitate the falling of the soil carried on the land scraping sheets, the phenomenon that the soil is adhered to the land scraping sheets 4 to influence the traffic capacity is avoided, as shown in fig. 2, the vertical distance value H from the circle center of the rim 2 to the connecting line between the outer end parts of the two adjacent land scraping sheets 4 is not smaller than the radius value R of the outer end face of the rim 2, as shown in fig. 6, when the rim 2 is walking, at least one land scraping sheet 4 is in contact with the ground, the situation that only the rim 2 is in contact with the ground and the land scraping sheets 4 are not in contact with the ground is avoided, the land scraping force during the walking is greatly improved, and the slipping is not easy.
