PURPOSE: A road adaptive type variable driving wheel and a variable driving assembly with the same are provided to automatically unfold a blade portion of the wheel when reaching rough roads by automatically sensing road conditions without a control part and a road condition sensor. CONSTITUTION: A road adaptive type variable driving wheel comprises a main driving part(10), multiple first auxiliary driving parts(20), multiple second auxiliary driving parts(30), and multiple variable driving parts(40). The main driving part is allowed to rotate. The first auxiliary driving parts are rotated in an engaged state with the main driving part. The second auxiliary driving parts are separated from the main driving part and rotated in an engaged state with the first auxiliary driving parts. The variable driving parts are respectively connected to the second auxiliary driving parts and rotated to be folded according to the rotation of the second auxiliary driving parts. The variable driving parts are composed of a head portion and a blade portion stretched and extended from the head portion. The variable driving parts vary in a first mode and a second mode. |
