Description

wheel propeller

Technical field:

The invention belongs to the field of dual-purpose vehicles for land and air, in particular to a wheel-type propeller.

Background technique:

We can see a phenomenon. In the recent period, people have been constantly attacking the compound vehicles that can drive on the ground and fly in the sky, although these impacts are too tragic. The predecessors continue to be the fallen martyrs, and the latecomers continue to step on the footsteps of the martyrs, surpassing them and advancing bravely. It can be seen that the technical difficulty and innovation span requirements of developing flying cars are far beyond people's estimates. Perhaps people who have been struggling in this field have never cared about the difference between pioneers and martyrs, because everyone is driven by curiosity and great dreams.

It is not difficult to find that various countries have invented and produced flying cars with various performances. However, it is still difficult to satisfy people on the two thematic goals of flying cars: 1. The ability to drive on the ground, due to the addition of a lot of necessary devices for flying, the flying car has lost its good vision to a large extent. Carrying capacity and good looks, as well as poor performance through. 2. At present, among the flying cars launched by various countries, especially the schemes in the process of commercialization, none of them have the vertical take-off and landing capability, and all of them use the taxi take-off method similar to that of fixed-wing aircraft. There is a big problem with this method. In densely populated areas, during times of war, and under natural disaster conditions, we simply cannot find a suitable take-off and landing site. That is to say, the flying ability of a flying car without vertical take-off and landing capability is basically a waste and decoration that is difficult to use.

With the continuous expansion of the scope of people's activities, the scale of cities is also expanding, and natural disasters occur frequently under climate change, the demand for more practical and breakthrough new transportation tools is increasing. Looking back at the above, the disadvantages of the current flying cars are as follows: 1. It is necessary to use the runway and other places to take off and land; 2. The ability to drive on the ground is poor; 3. The shape is not beautiful; It cannot be used in areas with narrow spaces such as cities, mountains, and dense forests.

Invention content:

In order to solve the above technical problems, the present invention provides a wheeled propeller.

A wheel-type propeller is characterized in that it includes an inner support ring, an outer buffer tire is arranged on the outside of the inner support ring, and a plurality of propeller blades are arranged inside the inner support ring, and the propeller blades are connected to the engine through the propeller shaft and the shaft coupling. connect.

The wheel-type propeller described above is characterized in that the outer end of the propeller blade is fixedly connected to the inner support ring.

The wheel-type propeller is characterized in that the outer end of the propeller blade is separated from the inner support ring, and the inner support ring is connected to the propeller shaft through a clutch.

The wheel-type propeller described above is characterized in that the propeller blades have multiple blades, and the propeller blades are evenly distributed inside the inner support ring.

The wheel-type propeller is characterized in that the wheel-type propeller is connected to the vehicle body through an overturned axle, and the wheel-type propeller can be rotated through the overturned axle so as to be parallel or perpendicular to the ground.

The wheel-type propeller of the present invention separates the two functions of ground driving and air flight, and generally requires the combination of multiple sets of devices to realize it. The present invention can be realized simply by changing the function of a single component, thus greatly reducing the use of parts The production cost is reduced, and the safety of the product is further improved at the same time; the appearance with a better overall sense can be designed by using the invention, the three-dimensional traffic in the continuously expanding city can be realized, the construction land of urban roads and airports can be reduced to protect land resources, and the The vehicle can switch freely between ground and sky modes, and the invention can also become a good army aviation weapon platform, possessing certain material transportation and regional monitoring capabilities.
