The invention relates to a multi-freedom-degree composite rolling wheel, and belongs to the field of general mechanical parts. In order to overcome the defects that a general universal sphere composite rolling ball is complex in mounting, obstacle crossing capacity is low, machining and manufacturing are complex, and the ball is not prone to adjusting when the ball encounters obstacles like handstone, the multi-freedom-degree composite rolling wheel combining the universal ball and a universal wheel simplifies the structure of the universal ball composite rolling ball and improves the obstaclecrossing capacity of the rolling wheel to a great degree, when the wheel encounters small obstacles like road face stone, due to the multi-freedom-degree mechanism, a vehicle body does not need to begreatly adjusted, the wheel can independently deflect by an angle to avoid the obstacles, and operation is more convenient; the composite rolling wheel has the following advantages that the structurecan be simplified, assembling is facilitated, under the same condition, the larger obstacle crossing capacity is achieved, machining and manufacturing are easy, operation is convenient, and manpoweris saved.
