Description

The invention relates to methods of transportation and is a device that can be used as a vehicle for a wide range of applications from children's toys and engineering robots to most types of existing transport.

The prototype of the invention is the ball rover Tiguntseva S.G. Patent 2297356 from 2002.12.05, where the movement of the inner device of the sphere is carried out by shifting the center of gravity located in the lower hemisphere. The disadvantage of the invention is the presence of a wheel between the center of gravity (engine) and the sphere, which structurally does not allow to fulfill the center of gravity at the boundary of the sphere and to achieve maximum stability. Also, the problem of control associated with the synchronization of rotation of the wheels within the sphere has not been solved, which complicates the applicability of the invention described by the author.

The aim of the invention is to use a method of movement by placing a self-propelled carriage inside the sphere, eliminating the indicated disadvantages and facilitating the applicability of the invention.

The technical result of the proposed invention is the combination of a sphere and a self-propelled cart with load-bearing wheels located in the same plane (classical or diamond-shaped arrangement of wheels), equipped with a propeller with a center of gravity shifted to the lower boundary of the sphere, with a structural element that excludes the self-propelled cart overturning during extreme acceleration. As a result of this, an increase in the stability, controllability of the invention is achieved, as well as optimization of the design and an increase in the versatility of use, passability, efficiency, safety of movement, in addition, it becomes possible to use other features of the invention.

The technical solution of the proposed invention is the use of a sealed sphere, as well as a sphere with valves that control communication with the external environment, which houses a cart with wheels located in one plane, a propeller, control elements, control and additional stability.

When the driving wheels of the trolley move, the sphere moves in the same direction, due to the displacement of the center of gravity. When turning, in the course of movement, the movement vector of the driving wheels and the center of gravity inside the sphere are shifted in the direction of the wheels turning, due to which the direction of movement of the sphere is changed. In the course of extreme acceleration when the trolley is displaced to the top of the sphere, the stop, rigidly attached to the frame, ensures that it is impossible to overturn inside the sphere, and when acceleration decreases, it ensures that the cart returns to the proper position. Thus, increased stability, handling, versatility, speed, safety and cross-country ability of the vehicle are provided.

The method of increasing versatility, cross-country ability and stability is based on the fact that the moving sphere has a center of gravity significantly shifted to the lower boundary, which achieves maximum stability during movement and the ability to overcome obstacles. The listed features and buoyancy provide versatility - comparable characteristics of movement on land, water and on difficult sections of the path.

The method for increasing controllability consists in the possibility of using the principles of a classic automobile turning mechanism and in the possibility of further increasing controllability by using a mechanism for turning all wheels or providing synchronous turning of two wheels with their diamond-shaped arrangement inside the sphere.

The method for increasing the efficiency of energy consumption is based on the fact that due to a small area of contact with the surface, a decrease in the friction force is achieved, due to rotation, the aerodynamic properties of the sphere increase.

The method of increasing the permeability is based on a large diameter of the sphere, which makes it possible to overcome vertical obstacles of comparable size, while the rotation of the sphere, with a small pressure on the surface, ensures the efficiency of movement over horizontal obstacles. The tightness and controlled connection with the atmosphere provide the possibility of stable characteristics of movement in swampy areas and water environments, as well as at the boundaries of environments.

The way to improve safety is based on the fact that the center of gravity is shifted to the bottom of the ball and on the total torque. When colliding with an obstacle, the center of gravity, tending to the obstacle, turns the payload to the part of the ball farthest from the obstacle, while the moment of rotation of the sphere distributes the collision energy. This provides security within the sphere.

Passive safety is achieved by the absence of striking protrusions made of solid material on the flat outer surface of the ball and by a torque that distributes the collision vector with an external object.

An example of how the method works. When the carriage "5" moves along the inner surface of the sphere "1", the torque from the wheels of the carriage "6" due to the friction force is transferred to the inner surface of the sphere "1", as a result of which the center of gravity "4" is shifted and a torque is created in the direction of movement of the carriage , and the sphere moves along the surface "7". The rotation of the wheels "6" provides the displacement of the center of gravity "4" and the vector of motion in the direction of the turn, and ensures the rotation of the sphere "1" in the corresponding direction. At the same time, the device "8" provides a safety stop in the event of extreme acceleration and movement of the trolley to the upper part of the sphere, at the end of the acceleration the center of gravity will shift downward under its own weight, the stop, while providing protection against trolley overturn

The proposed method of movement allows increasing the indicators of stability, controllability, versatility, cross-country ability, efficiency, safety and speed of movement.
