Moving blade raceway

Abstract

The invention is a means of propelling a vehicle such as a wheel or a track, comprising one or more moving parts called blades which can tilt around an axis different from the direction of movement of the vehicle to move from a position allowing propulsion on the ground to a position ensuring propulsion in a fluid. The main applications are land vehicles which can travel both on roads and on uneven or muddy ground and sail on water or, in certain versions, take off and land vertically and fly in all directions, as well as a boat, a submarine or an aircraft which can land on a beach or roll on shallows.

Description

Title of the invention: Rolling track with moving blades Technical field

[0001] The invention is a wheel or track raceway, improved to adapt to the environment on or in which a vehicle moves. Prior art

[0002] CN107962922A of April 27, 2018 by CUI JIE, LI QIAN, QIAO YANXIN, WANG YI, CHANG QI, ZHUANG CHENYI, SUN HONGLAI, CHEN ZHIPENG and CHEN YANG is known, which describes a track provided with a plurality of paddles arranged on the outer end faces of the tracks and which provide propulsion for an amphibious vehicle in water. These paddles are permanently perpendicular to the outer faces of the tracks, so that they are not well suited to the movement of the vehicle on hard ground.

[0003] We also know CN108422821 (A) of August 21, 2018 by SUN SHILIANG which describes a similar device, which has the same drawback.

[0004] We also know CN110733305 (A) of January 31, 2020 by WANG XINGBO, LI XINYU and ZHANG SIMING which describes a blade comprising a plurality of flexible blades ensuring the propulsion of a vehicle in water, but which is also poorly suited to the movement of a vehicle on hard ground.

[0005] We also know US 10259280 (B 1) of April 16, 2019 from ROE RICHARD DARIN [US] which describes a vehicle equipped with wheels allowing it to roll on ground, which have blades on their lateral part to ensure the propulsion of the vehicle on water, but the efficiency of the drive on water of this device is low.

[0006] We also know BRI 12023023953 (A2) of January 30, 2024 by HOFREITHER KLE-MENS [AT] and KINAST LUKAS [AT] which describes an aircraft equipped with two rotating propulsion devices for generating a thrust vector each comprising blades whose periodic adjustment creates a thrust vector normal to the axis of rotation of the rotor. Such propulsion devices are often called cyclorotors.

[0007] Finally, RU2060203 (Cl) of May 20, 1996 by FEDCHISHIN VITALIJ G [RU] is known, which describes a device comprising such cyclorotors ensuring the propulsion of a ship which has a means of accessing a flat shore by the support of drums of propulsion discs which can roll along an underwater plane. Technical problem

[0008] The devices described above do not allow a vehicle to be ensured as good a quality ride on hard ground as is permitted with wheels or tracks, as well as efficient aquatic propulsion or flight based on the principle of paddle wheels or cycloro-tors. Brief description of the drawings

[0009] The invention will be well understood, and other aims, advantages and characteristics thereof will appear more clearly on reading the description which follows, which is illustrated by Figures 1 to 2.

[0010] [Fig-1] is a side view of a tracked vehicle, the blades of which are in a so-called propulsion position on the ground.

[0011] [Fig.2] is a side view of a tracked vehicle, the blades of which are in a so-called propulsion position in a fluid. Statement of the invention

[0012] The invention is a means of propelling a vehicle such as a wheel or a track, characterized in that it comprises at least one mobile part called a blade which can tilt around an axis different from the direction of movement of said vehicle to pass from a position called propulsion on the ground to a position called propulsion in a fluid. Detailed description of the invention

[0013] The principle of the present invention is to provide the raceway of a wheel or track of a vehicle with movable portions which can serve as blades for its propulsion in a fluid, whether mud, water or air. These movable parts are hereinafter and hereinafter referred to as blades.

[0014] Such a blade can tilt around an axis different from the direction of movement of said vehicle to move from a so-called propulsion position on the ground to a so-called propulsion position in a fluid. Advantageously, this axis is perpendicular to the direction of movement of the vehicle. It can also advantageously be horizontal.

[0015] In the case where the propulsion means is a wheel, a blade may be a portion of this wheel which can pivot around an axis substantially parallel to the axis of rotation of the wheel.

[0016] In the case in which the propulsion means is a track, a blade may be a portion of this track which can pivot around an axis substantially parallel to the axis of rotation of one of said wheels supporting said track.

[0017] In both cases, it is advantageous for the position of said blades to vary between said so-called ground propulsion position and said fluid propulsion position, depending on their position during the advancement of the vehicle. They may, for example, be substantially perpendicular to the direction of movement of the vehicle in the lower part of the propulsion means and parallel to this direction. of movement in the upper part of the propulsion means. This differentiates them from the old paddle wheels whose upper part could hit waves which opposed the progress of the boat.

[0018] Advantageously, the propulsion means is provided with a means for determining the position of said blades according to different rules to adapt to the environment on or in which the vehicle is moving, the user or a computer choosing to keep them permanently in a so-called propulsion position on the ground when the vehicle is traveling on the ground, and to make them pass cyclically from this position to a so-called propulsion position in a fluid when it is traveling on water. Rules for positioning the blades can be chosen according to the nature of the terrain, which can be analyzed by computer to determine the most appropriate rule.

[0019] All means known to those skilled in the art familiar with cyclorotor technologies, which make it possible to vary the position of the blades as a function of their position in the cycle, can be implemented.

[0020] A blade advantageously comprises only a portion limited to the raceway of said propulsion means, that is to say to the part of this means which can actually come into contact with the ground. This makes it possible, for example, to continue to benefit from the flexibility of a tire in the case where the propulsion means is a wheel.

[0021] Maintaining a blade in the so-called propulsion position in a fluid is advantageously elastic, the resistance of the ground or the fluid on which it moves being able to modify this position to temporarily bring it closer to the so-called propulsion position on the ground. This makes it possible to travel on irregular surfaces such as uneven ground or shallows.

[0022] The invention is also a vehicle provided with a propulsion means according to the invention described above, and the method of propelling a vehicle by a propulsion means according to the invention described above. Applications

[0023] The main applications of the present invention are land vehicles that can travel on roads as well as on uneven or muddy ground and sail on water or in certain versions take off and land vertically and fly in all directions, as a boat, a submarine or an aircraft that can land on a beach or drive on shallows. These vehicles can be used for leisure or work but also for military combat. They can be piloted by humans or be drones.
