Deformable wheel

Abstract

A deformable wheel is composed of a rubber ring, a track, fixed spokes, pneumatic spokes, air guiding pipes, transmission wheels, a transmission shaft, an air pressure regulator and a controller. Thefixed spokes are located on the upper portion of the wheel, and the pneumatic spokes are located on the lower portion of the wheel; the pneumatic spokes are connected with the air pressure regulator through the air guiding pipes, the air pressure regulator regulates the pressure in the pneumatic spokes, and thus the pneumatic spokes can be extended or shortened; the air pressure regulator is connected with a power supply of a vehicle through the controller; the transmission wheels are mounted at the outer ends of the fixed spokes and the pneumatic spokes, the track is mounted on the outer sides of all the transmission wheels, and the rubber ring is mounted outside the track; and the transmission shaft is connected between a power output shaft and the transmission wheels and outputs power from the power output shaft to the transmission wheels, and the transmission wheels drive the track to rotate. Through the controller, the air pressure regulator can be controlled to regulate the pressure in all the pneumatic spokes, so that the pneumatic spoke in the middle is shortened, the pneumatic spokes on the two sides are extended, and accordingly the contact area of the rubber ring outsidethe track and the ground is increased.

Description

technical field [0001] A deformable wheel. Background technique [0002] Existing wheels usually do not have the function of deformation, and can only maintain the same shape when driving on various grounds. Vehicles with relatively wide wheels or conventional crawlers will cause the vehicle's dynamic force due to the large friction between the wheels or crawlers and the ground. Larger losses will weaken the dynamic performance of the vehicle and increase fuel consumption. For vehicles with relatively narrow wheels, although the friction between the wheels and the ground is small when driving on dry and flat ground, the power loss of the vehicle is small, which can reduce fuel consumption, but when driving on wet and slippery ground, the friction force will Insufficient and slipping or even breaking down.

[0002] Existing wheels usually do not have the function of deformation, and can only maintain the same shape when driving on various grounds. Vehicles with relatively wide wheels or conventional crawlers will cause the vehicle's dynamic force due to the large friction between the wheels or crawlers and the ground. The loss is large, the power performance of the vehicle is weakened, and the fuel consumption is increased

For vehicles with relatively narrow wheels, although the friction between the wheels and the ground is small when driving on dry and flat ground, the power loss of the vehicle is small, which can reduce fuel consumption, but when driving on wet and slippery ground, the friction force will Insufficient and slipping or even breaking down

In order to prevent the wheels from slipping on icy, snowy or muddy roads, anti-skid chains are usually used to increase the friction between the wheels and the ground to reduce the occurrence of wheel slippage, but the loading and unloading process of anti-skid chains is often cumbersome and not convenient enough to use
