Abstract
The invention discloses a thread walking device. The thread walking device comprises an vehicle frame, two or more parallel walking screws, and a transmission mechanism. The invention uses the walking screws rotating in the opposite direction, and adopts an novel vehicle walking manner, in which a drive device drives along the axial direction of the walkinhaodeg screw by using the reverse force produced by threads wound around the walking screw after touching ground; the main body of the vehicle frame is a hollow structure. The drive screw is made of elastic materials, thus the weight of the vehicle frame can be effectively reduced, and the thread walking device can float on water surface after falling into water. By using a difunctional bearing capable of bearing radial forces and axial forces, the off-road driving performance of the walking device can be improved in the no-road region, such as intertidal zones, wetlands, and snow mountains and so on.
