[0042] In order to better understand the present invention, the following is a further description with examples:
[0043] The design method of a flexible diameter reducing mechanism for a variable diameter wheel of the present invention, and its operation process is as follows figure 1 As shown, including the following steps:
[0044] Step 1: Determine the design variables of the reducing mechanism and the geometric relationship between them;
[0045] Sub-step 1: Assuming that the wheel legs can maintain structural stability during the diameter reduction process (the spokes maintain an isosceles trapezoid shape), such as Figure 2a , B, Figure 3a As shown in b, according to the geometric relationship between the two extreme positions of the variable-diameter wheel opening and closing, the projections in the horizontal direction are equal to:
[0046]
[0047]
[0048] Substep 2: Subtract formula (1) and formula (2) to obtain:
[0049]
[0050] Then the length of the spoke connecting ...
