Embodiment Construction

[0021] figure 1 It is a structural schematic diagram of the present invention. As shown in the figure, the walking wheel walking mechanism of the present embodiment includes a vehicle frame 3, a driving wheel 7 arranged at the bottom of the vehicle frame 3 and a foot wheel 5 for balancing the vehicle frame 3; the foot wheel 5 can be locked or rotated to The end face of the wheel is perpendicular to the vertical direction. The wheel walking mechanism of this embodiment adopts the configuration principle of a rickshaw and a trolley, and the driving wheel 7 mainly plays a load-bearing role. Cooperating with the vehicle frame 3 of the truss structure, the load-bearing capacity of the structure can be effectively improved Therefore, the present invention has higher bearing capacity. When the caster wheels 5 at both ends of the vehicle frame 3 are running on structured terrain, the caster wheels 5 are used for auxiliary support. Rotate as far as the vertical direction is vertical, ...

Abstract

The invention discloses a walking wheel walking mechanism, which comprises a vehicle frame, a driving wheel arranged at the bottom of the vehicle frame, and a caster wheel for balancing the vehicle frame; the caster wheel can be locked or rotated until the wheel end face and The vertical direction is vertical, and the walking mechanism of the walking wheel of the present invention can adapt to unstructured terrain and has functions such as transportation, drilling, and pushing and pulling, so as to overcome the shortcomings of existing walking wheels with poor running comfort, so as to improve the performance of the wheel on unstructured terrain. Passability and good ride comfort.

Description

technical field [0001] The invention relates to the field of walking mechanisms, in particular to a walking wheel walking mechanism. Background technique [0002] When traditional wheels walk on soft unstructured terrain such as sandy ground, they will suffer from poor passability or even inability to walk due to subsidence and slippage. In order to solve the problem of vehicles operating on such unstructured terrain, domestic and foreign scholars have proposed and developed a variety of Walking wheel mechanism, and the existing walking wheel mechanism is actually a polygon that can roll. When a polygon rolls on the ground, it will produce a polygon effect, that is, when the walking wheel is rolling, its wheel center will fluctuate up and down, and the speed will not change. Uniform, for example, when the number of legs is 4, the difference between the maximum and minimum speed of the wheels can be doubled, and in some cases, such as when turning, the speed of the left and r...
