Problems solved by technology

[0006] 2. Due to the restriction on the change rule of the length of the telescopic rod, the position of the support point of the telescopic rod on the rim is far from the stress point of the rim, which can be obtained by calculation, which leads to the support of the "X" spokes on the rim The effect is not good, that is, the force performance of the rim structure of the rim is not good
[0007] 3. The "X" type spokes use telescopic rods, including sliding pairs. When the sliding pairs are closely matched, it is easy to cause jamming, and the expansion and contraction is not flexible, making the deformation unreliable; when the sliding pairs are loosely matched, the gap between the moving pairs Larger, so that the shaking of the telescopic rod is large, resulting in an increase in the empty space of the entire rim structure, that is, the rim cannot maintain a circular shape, which will reduce the motion accuracy and structural reliability

Abstract

The invention discloses a synchronous telescopic deformation type track leg composite traveling device which comprises a wheel rim, a travel driving mechanism and a deformation wheel component, wherein a track is coated outside the wheel rim; the deformation wheel component comprises a deformation motor and more than three supporting lead screws; the deformation motor is positioned in the middle of the wheel rim; nut joints are mounted on the supporting lead screws by thread fit; the nut joints are contacted with the wheel rim so as to form linkage support; the supporting lead screws are connected with the output end of the deformation motor through a transmission component and are rotated under drive of the deformation motor; and in the rotating process of the supporting lead screws, the nut joints translate on the supporting lead screws so as to change the shape of the wheel rim. The device disclosed by the invention has the advantages of simple and compact structure, flexible motion manner, high terrain adaptive capacity and the like.

Description

technical field [0001] The invention mainly relates to the field of machine walking devices, in particular to a synchronous telescopic and deformed wheel-foot-leg compound walking device, which is especially suitable for mobile robots, engineering vehicles and other fields. Background technique [0002] As we all know, small ground mobile robots used for dangerous operations such as fires, mine disasters, and nuclear leaks have become another hot spot in the field of mobile robot research due to their small size, low cost, strong survivability, and flexible movement. The most basic walking modes of mobile robots are wheeled, crawler and legged. Among them, the wheeled structure runs smoothly, high speed and high efficiency, but its ability to overcome obstacles and adapt to complex terrain is very limited; the grounding ratio of the crawler walking device is The pressure is small, and it can adapt to soft terrain such as sandy soil and mud, but it also has the disadvantages ...
