Wheel mechanism with adjustable radius

Abstract

The invention discloses a wheel-type mechanism with adjustable radius, which comprises a wheel composed of a plurality of spokes. On the radius position; it also includes a radius adjustment component and a motor drive component. The motor drive component includes a double output shaft motor arranged in the center of the wheel and installed through the wheel frame. Active bevel gears are installed on the left and right output shafts of the double output shaft motor; The radius adjustment assembly includes screw rods and nuts, guide rails and sliding seats corresponding to the spokes. The guide rails are arranged radially on the wheel frame, and the spokes are installed on the corresponding guide rails through the corresponding sliding seats. Fitted to the corresponding screw mandrel and installed on the corresponding wheel spoke, the driven bevel gear at the inner end of the screw mandrel meshes with the corresponding driving bevel gear. The invention can adapt to different complex terrains, reduces the sense of undulation and impact during the operation of the wheels, and improves the obstacle-surmounting ability of the wheels.

Description

technical field [0001] The invention relates to a wheel structure, in particular to a wheel mechanism with adjustable radius. Background technique [0002] With the development of science and technology and the improvement of human living standards, people have higher and higher requirements for the performance of transportation tools. On the one hand, when the wheeled mechanism moves on flat ground, it is required to have good dynamic characteristics, no ups and downs in walking, and high efficiency; on the other hand, when the wheeled mechanism moves on uneven ground, it is required not only to walk smoothly, No major impact, but also has a certain ability to overcome obstacles. [0003] The shaft of the ordinary wheel mechanism is fixedly installed at the center of the wheel. When driving on uneven ground, it will not only produce bumps with the change of road conditions, but also have a sense of undulation and impact; the wheel mechanism with adjustable eccentricity can...

[0003] The shaft of the ordinary wheel mechanism is fixedly installed at the center of the wheel. When driving on uneven ground, it will not only produce bumps with the change of road conditions, but also have a sense of undulation and impact; the wheel mechanism with adjustable eccentricity can Adjust the distance between the shaft and the wheel center according to the road conditions, but most of these mechanisms are realized by changing the distance between the power shaft and the wheel center (the larger the distance, the stronger the ability to overcome obstacles), and it does not change the wheel body radius of
