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

[0063] 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.

[0064] 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 203a-f differentially rotate, and because the driving sprocket 201 is connected with the six groups of driven sprockets 203a-f through the roller chain 202, so the driving sprocket 201 will drive the driven sprockets 203a-f to rotate, thereby driving the worms 301a-f connected thereto to rotate synchronously. Because the worm gears 302a-f and the worms 301a-f remain in mesh, the rotation of the ...

Abstract

A deformable wheel mechanism is composed of a hub portion, a chain wheel set and rotating mechanisms. An axle shaft in the hub portion is connected with a flange fixed on a hub through splines to provide power for movement of the whole deformable wheel. A deformable sleeve hollowly sleeves the axle shaft and is connected with a driving chain wheel of the chain wheel set through the spline. Chain wheels of the chain wheel set are positioned through corresponding unthreaded holes in a web. The rotating mechanisms are evenly disposed on the inside of the hub and corresponding to driven chain wheels. The hub is the main support, and tire blocks of the rotating mechanisms bear the ground acting force and transmit the same to the hub. As an unconventional walking mechanism, the deformable wheel mechanism is safe and reliable, capable of mounting and adjusting and convenient to operate and has the advantages that by changing form of the wheels, acting force between the wheels and the deep and soft grounds is increased to improve driving force to the vehicle by the ground, thus driving performance of the vehicle on the conventional ground is guaranteed, and meanwhile, technical requirement on the vehicle to run on the deep and soft ground is increased.

Description

【Technical field】 [0001] 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. 【Background technique】 [0002] 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. [0003] 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 walking mechanism...
