Deformable wheel

Abstract

Provided is a deformable wheel. Spokes can extend or contract in the radial direction, and a cam in a hub controls a hydraulic loop of the spokes. When the spokes rotate to be close to the vertical line of the surface of a vehicle frame by a certain angle, the hydraulic loop of the spokes is closed by the cam, and the spokes can bear weights; when the spokes rotate away from the vertical line of the surface of the vehicle frame by a certain angle, the hydraulic loop of the spokes is opened by the cam. The shape of the wheel changes along with the change of the shape of pavement, and therefore the wheel can cross over various barriers. Due to the fact that the angle of the cam can be adjusted, the height of the axis can be adjusted, and a vehicle body can be kept stable on an inclined pavement or a curve. Due to the fact that the pressure of liquid in the hub can be adjusted, proper pre-pressure can be adjusted and applied to a flexible pavement, and a vehicle with the wheels can run quickly and accurately on various rugged pavements.

Description

technical field [0001] The invention relates to a deformable wheel, which belongs to the fields of walking machines, off-road vehicles, wheelchairs and the like. Background technique [0002] Nowadays, many countries are actively researching the mobile handling technology of complex terrain, and it is of great significance and wide application for vehicles or machines to quickly pass through various rough roads. Various machines, as human production tools, reduce labor intensity and improve production efficiency. However, in many occasions, machines cannot or are difficult to reach, and the application of automation technology achievements is limited. It is very important for people who need a wheelchair to move smoothly and safely over various obstacles. At present, vehicle shock absorption mainly relies on the damping parts on the suspension. However, considering the weight of the vehicle body and the need to bear greater pressure on the outer wheels when turning, the sho...

AI Technical Summary

Problems solved by technology

At present, vehicle shock absorption mainly relies on the damping parts on the suspension. However, considering the weight of the vehicle body and the need to bear greater pressure on the outer wheels when turning, the shock absorption parts should not be too soft. When there is a sudden bump on the road, the wheels will Generate an upward jump, due to the inertia of the wheel itself, the shock absorption system is difficult to absorb this energy, and the shock absorption effect is limited

The current walking machines rely on cameras or sensors to detect ground conditions. For soft roadbeds (such as leaf piles or soft soil, etc.), it is difficult to predict the height after compression, and the machine may be in danger of overturning

For robots that imitate human or animal walking, the walking speed is limited due to the discontinuity of foot movements
