Wheel type mechanism of which radius can be adjusted

Abstract

The invention discloses a wheel type mechanism of which the radius can be adjusted. The wheel type mechanism comprises a wheel formed by a plurality of wheel spokes, wherein the wheel comprises the wheel spokes, and further comprises a radius adjusting assembly and a motor driving assembly; the wheel spokes are arranged on the left side and the right side; more than three wheel spokes on each side are uniformly distributed on the periphery and are positioned at the same radius positions; the motor driving assembly comprises a dual-output shaft motor which is arranged in the center of the wheel and is mounted through a wheel frame, wherein driving bevel gears are respectively mounted on the left output shaft and the right output shaft of the dual-output shaft motor; the radius adjusting assembly comprises screw rods, nuts, guiding rails and sliding bases, which are arranged corresponding to each of the wheel spokes; the guiding rails are radially arranged on the wheel frame; each of the wheel spokes is mounted on the corresponding guiding rail through the corresponding sliding base; the screw rods are radially arranged; the nuts are screwed with the corresponding screw rods and mounted on the corresponding wheel spokes; driven bevel gears at the inner ends of the screw rods are meshed with the corresponding driving bevel gears. The wheel type mechanism disclosed by the invention can adapt to different complex terrains, the sense of undulating and the sense of impact when the wheel travels are reduced, and the obstacle crossing capacity of the wheel is improved.

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
