In addition, there are various combinations in each row of adjacent or periodically spaced support sheets 603, as shown in fig. 6, fig. 6 (1) is a schematic view of a structure in which the support sheets are not twisted, fig. 6 (2) is a schematic view of two adjacent support sheets 603 having different twisting directions and one support sheet 603 having a different twisting direction, and fig. 6 (3) is a schematic view of all support sheets 603 having the same twisting direction, wherein fig. 6 (3) is easy to adjust the rotation structure 103, and fig. 6 (2) requires that the connection bars 503 of the rotation structure 103 are changed from the initial adjacent connection to one connection at intervals, for example, two or three connection intervals are provided, and a combination of support sheets 102 with a certain periodic interval can be realized. In summary, the supporting members 102 can be arranged in many combinations according to the number of rows, directions and periodic intervals.
In particular, the connection between the rotating structure 103 and the support 102 is shown in fig. 10, the specific adjustment force transmission path being: the adjusting ring 104, the adjusting rod 403, the cylindrical rod 402, the clamping part 405, the support 102 and finally the adjusting ring 104 is fixed on the hub 101; the supports 102 of each row are controlled by a rotating structure 103 of the respective row.
In one embodiment, the clamp 405 is formed with a slot into which the other end of the support 102 fits such that the support 102 can translate along the length of the slot. Specifically, shear deformation occurs. It should be noted that the twisting in the present invention includes rotational deformation, tensile deformation, and shear deformation. The support 102 may also be variously combined by shear deformation, as shown in fig. 7, and fig. 7 (1) is a schematic view of the first sub support sheet 6011 and the second sub support sheet 6021 being undeformed; fig. 7 (2) and 7 (3) are schematic diagrams illustrating the first sub-support plate 6011 and the second sub-support plate 6021 being offset in opposite directions; fig. 7 (4) and 7 (5) are schematic diagrams illustrating that the offset directions of the first sub-support plate 6011 and the second sub-support plate 6021 are the same. The adjustable rigidity is realized mainly by adjusting the displacement direction and the displacement magnitude of the top end of the support member 102. Specifically, the connection position of the rotating structure 103 and the supporting member 102 may be two forms, in which the upper end of the supporting member 102 may move along a direction parallel to the axial direction, so as to realize the shear deformation of the supporting member 102 along the axial direction, so as to realize the adjustable stiffness. As shown in fig. 9, fig. 9 is a schematic view of the translational deformation of the supporting member according to the embodiment of the present invention, where the width of the clamping structure may be slightly larger than the width of the supporting member 102, so that the supporting member 102 may be adjusted along the width direction of the clamping structure, the clamping structure may be interference-fit after a certain displacement is applied, the range of the adjustment displacement is determined by the difference between the width of the clamping structure and the width of the supporting member 102, and the adjustment direction has two directions, namely positive and negative directions; the cylindrical rod 402 can also be translated and fixed along the axial direction by adjusting the position of the hole where the cylindrical rod 402 is connected with the hub 101, such as the structure diagram of the hub 101 in fig. 2, and by arraying the second mounting holes 201 along the axial direction by a plurality of holes. The support member 102 can be sheared and deformed by the two adjusting modes, so that a certain shearing force can exist in the support member 102, the stress of the support structure is more uniform, the rigidity is adjustable, and the service life of the support member 102 is prolonged.
In summary, the stiffness adjustment of the present invention can be achieved from multiple dimensions, and the support member 102 can be twisted, stretched, sheared, etc.
In addition, if the number of rows of the supporting members 102 is not only two, the two outermost rows at the two ends can be adjusted and fixed by using the adjusting ring 104, and after the rotation direction or displacement of the remaining middle supporting members 102 can be adjusted by the rotating structure 103, the adjusting rod 403 is directly connected with the boss hole at the inner side of the hub 101 by a screw or a bolt, so that the adjustment and fixation of the inner multiple rows of supporting members 102 are realized. The bearing is realized by utilizing the pulling-shearing-twisting multi-state force, and the uniform stress of the spoke is more easily realized by the twisting force.
In one embodiment, referring to fig. 1, the casing comprises a tread 106 and a cushioning layer 105 disposed inside the tread 106, one end of the support member 102 is connected to the cushioning layer 105, and both the cushioning layer 105 and the support member 102 are made of an elastic material. The buffer layer 105 is made of a high-elasticity high-molecular polymer material and plays a role in buffering and damping in cooperation with an elastic supporting structure. Both such cushioning layer 105 and support member 102 may be constructed of resilient materials such as natural and synthetic rubbers, polyurethanes, foamed rubbers, foamed polyurethanes, block copolymers of block copolyesters and polyamides (such as copolyamides or polyether block amides). The buffer layer 105 can also be embedded with a plurality of reinforcing layers, and the reinforcing layers adopt fiber cords as reinforcing materials, and are mainly one or more of nylon, cotton threads, rayon, polyester fibers and steel wires. The buffer layer 105 may be integrally formed with the support member 102 by casting, or may be connected by gluing, or may be connected by mechanical mortise-tenon connection or assembly connection. The tread 106 has a pattern block on the outer side, which is mainly made of traditional rubber material and adopts low rolling resistance and anti-skid material.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents made by the claims and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
