Problems solved by technology

Traditional wheeled vehicles are prone to slipping or even unable to move on deep and soft ground, and cannot achieve such a function. Unconventional walking mechanisms can be used to solve this problem due to their strong adaptability and passability on soft ground.

specific Embodiment approach

[0069] When driving on conventional hard roads such as highways, the wheels remain in a rimless state without deformation, and the driving principle is the same as that of conventional wheels.

[0070] When driving on deep soft ground such as swamps and tidal flats, the deformation sleeve 102 is driven to rotate relative to the half shaft 101. Since the driving sprocket 201 is synchronized with the deformation sleeve 102, the driven wheel sprockets 203a-f are connected to the hub 101 and the half shaft 101. Synchronously, so at this time the driving sprocket 201 and the driven sprocket a203a-f rotate at a differential speed, and because the driving sprocket 201 is connected with six groups of driven sprockets a203a-f through the roller chain 202, so the driving sprocket 201 will drive the driven sprocket a203a-f to rotate, thereby driving the worm a301a-f connected to it to rotate synchronously. Because the worm gears a302a-f and the worms a301a-f keep meshing, the rotation of...

Abstract

A deformable wheel mechanism, which is composed of a hub part, a sprocket set and a rotating mechanism; the half shaft in the hub part is connected to the flange fixed on the hub through a spline, which provides forward power for the entire deformed wheel, and deforms The sleeve is emptied on the half shaft and connected with the driving sprocket in the sprocket group through splines; each sprocket in the sprocket group is fixed through the corresponding light hole on the web; the rotating mechanism is evenly distributed inside the hub, Corresponding to the driven sprocket respectively; the hub is the main support, and the tire block in the rotating mechanism bears the ground force and transmits it to the hub. The present invention is an unconventional walking mechanism that is safe, reliable, installable and easy to operate. By changing the shape of the wheel, the interaction form between the wheel and the deep, soft ground is increased to improve the driving force of the ground to the vehicle, so as to ensure that the vehicle can operate normally The technical requirements for improving the vehicle's passability on deep and soft ground while maintaining the driving ability on the road.

Description

[0001] 【Technical field】 [0002] The invention relates to a deformable wheel mechanism, specifically, a walking mechanism that can be used not only on roads but also on deep muddy ground with no hard bottom, and belongs to the technical field of engineering machinery. [0003] 【Background technique】 [0004] About 50% of the earth's land area is inaccessible to vehicles. There is a type of deep muddy ground that is soft and has no hard bottom, such as some paddy fields, tidal flats, wetlands and swamps in the south, where it is difficult for animals and humans to move without means of transportation. [0005] In response to this problem, people have designed some special-purpose unconventional running gears, and these running gears will support the vehicle body at first, and will provide driving traction simultaneously. Traditional wheeled vehicles are prone to slipping or even unable to move on deep and soft ground, and cannot achieve such a function. The non-conventional wa...
