Bionic low-vibration walking wheel

Abstract

The invention discloses a bionic low-vibration walking wheel. The bionic low-vibration walking wheel comprises a first wheel leg mechanism and a second wheel leg mechanism, the first wheel leg mechanism is fixedly arranged on the second wheel leg mechanism through a plurality of connection bolts, and the first wheel leg mechanism and the second wheel leg mechanism are structurally identical. The bionic low-vibration walking wheel is designed on the basis of bionic engineering principles, the synergic foot movement of an ostrich and the energy absorption and vibration attenuation characteristics of the metatarsophalangeal joint tendons of the ostrich. When the walking wheel travels on the sandy ground and hard ground, wheel center fluctuation and vibration are evidently weakened while a traction performance of a normal walking wheel is achieved. The bionic low-vibration walking wheel is simple in structure, stable in operation, excellent in sinking resistance, low in soil disturbance according to the wheelmark and superior to a traditional walking wheel in traction performance. In addition, the bionic low-vibration walking wheel is low in wheel center fluctuation, the vibration attenuation effect is more evident along with the increasing of the rotation speed, and accordingly the comfortableness of a driver is improved, vehicular mechanical parts are less prone to fatigue failure, and the bionic low-vibration walking wheel is suitable for extensive popularization and application.

Description

technical field [0001] The invention relates to the field of bionics, in particular to a bionic low-vibration walking wheel. Background technique [0002] my country's deserts, Gobi and semi-arid areas have a total area of ​​1.308 million square kilometers of sand, accounting for about 13.6% of the country's total land area. etc. all need high-performance desert off-road walking mechanism. In addition, with the successful landing of Chang'e-3 on the moon and the start of Mars exploration, deep space exploration has received unprecedented attention. The study of deep space patrol probes traveling in complex ground environments such as soft sand has not only scientific significance but also far-reaching strategic significance. , because the walking wheel has the characteristics of high passability in the soft ground environment, in order to improve the traction of the vehicle on the soft road, researchers have developed various forms of walking wheel structures. However, ther...

Problems solved by technology

[0003] The purpose of the present invention is to solve the polygonal effect of the above-mentioned existing walking wheels. The wheel legs will explode a large instantaneous impact force at the moment of contact with the hard ground. The vibration caused by such impact force makes it difficult for drivers and passengers to adapt. To cause problems such as fatigue damage to the mechanical parts of the vehicle, and provide a bionic low-vibration walking wheel
