Description

The technical field to which the invention relates.

The invention relates to vehicles that use the conversion of rotational motion into translational and additionally uses the work of gravitational forces.

The level of technology.

Inertial propulsors are known, the action of which is based on the rotation of unbalances with an angular velocity that changes during one revolution, due to which a difference in the moments of centrifugal forces is formed, which creates a traction force in the direction of a larger moment of force.

A propulsion device of a vehicle is known, comprising a housing, shafts installed in it, on which flywheels are mounted movably (unbalances), and mechanisms for rotating the flywheels around the shafts. The mover is made of two interconnected and symmetrically located identical parts, in each of which the flywheels contain a frame structure, and the shafts are cranked. The mechanism of rotation of the flywheels around the crankshafts consists of drums and a wheelset movably mounted on the lateral parts of the shafts. The wheelset is connected by a gear to the corresponding drum and connected to the engine. The drums are made in the form of two gears connected by side rods (see RF patent 2392165, CL B62D 57/02, CL F03G 3/08). Due to the design of the drums transmitting rotation to the flywheels with a change in the points of application of force in one rotation period, the angular speed of the flywheels changes from maximum in the upper position to minimum in the lower one. The movement is due to the difference in angular speeds of rotation of the flywheels and, accordingly, the difference in centrifugal forces. The specified invention does not allow to achieve high efficiency due to the fact that in each rotation period there are centrifugal forces opposite to the direction of movement - in the first half-cycle they act in the direction of movement of this device, in the second half-cycle in the direction opposite to its movement.

An inertial propulsion device is also known, the action of which is based on the rotation of unbalances with an angular velocity that changes during one revolution. The mover contains two groups of four unbalances. Each unbalance is mounted on the driven shaft and is associated with an individual drive. Each mechanism for rotating the driven shaft with an angular speed that changes during one revolution contains a crank mounted on the drive shaft and a translational kinematic pair formed by the crank and groove in the unbalance. Unbalanced driven shafts and drive shafts are installed in separate housings. In each group, the unbalances in pairs are rotated 180 ° relative to each other, and 90 ° relative to the unbalances of the other group. The adjacent driven shafts rotate in mutually opposite directions. Drive shafts are interconnected by pairs of identical gears (see RF patent 2097600, class F03G / 00, class B 1/16). The principle of creating traction is similar. Cranks rotating at a constant speed apply force to unbalances for one revolution at different distances, smoothly changing their angular velocity. The presence of a large number of unbalances with a shift of each group by 90 ° makes it possible to achieve greater smoothness of movement, but does not allow to achieve high efficiency, again due to the fact that in each rotation period each of the half-period unbalances works against the movement of the device. In addition, the design is quite complicated due to the presence of a large group of unbalances and requires an additional design for the direct movement of the mover on the surface of the movement.

The aim of the present invention is to provide a compact vehicle with increased efficiency due to the fact that the body of the inertial propulsion device is a rolling element on the surface, and the movement is created by continuous rotation of the unbalances, the centrifugal forces of which in the first half-cycle of rotation are directed to the horizontal movement of the propulsion, and in the second half-cycle serve to increase its potential energy by raising the center of mass of the inner cylinder of the propulsion housing, which returns in the next half-cycle tin in the form of kinetic energy of motion.

Disclosure of the invention.

This goal is achieved by the fact that in an inertial propulsion device comprising a housing, driven shafts installed in it with unbalance fixed on each of them, rotated in mutually opposite directions, and mechanisms for rotating the driven shafts, while the unbalances are rotated 180 °, according to the invention, unbalances rotate coaxially in a vertical plane with constant angular velocity, and the body consists of two cylinders - internal and external, with the possibility of coaxial rotation of the external cylinder relative to the internal one hundred in the direction of movement of the inertial propulsion device, while the rotation in the opposite direction is limited by the locking mechanism, and the inner cylinder is an unbalance with a displaced center of mass vertically from the axis of symmetry due to the location in its lower part of the engines, mechanisms for rotating driven shafts, their structural elements fastenings and unbalanced loads. The inventive inertial propulsion improves efficiency and, due to the simplification of the design, its compactness is achieved.

The inventive inertial propulsion device comprises a housing consisting of an external cylinder 1 rotating on the outer surface of the inner cylinder 2, due to the rolling elements 3. The rotation of the external cylinder is freely carried out in one direction in the direction of movement of the inertial propulsion device. In the opposite direction it is limited by locking mechanisms 4, 5. The following elements are placed in the inner cylinder: two unbalances 6, 7 mounted on one axis coinciding with the common geometric axis of the cylinders and rotated 180 ° relative to each other; an engine 8 transmitting rotation to the unbalance 6 through the rotation mechanism of the driven shaft 9, an engine 10 transmitting rotation to the unbalance 7 through the rotation mechanism of the driven shaft 11; unbalanced loads 12, 13; common axis 14. The shape of the inner cylinder is shown in FIG. 4. Due to this design of the inner cylinder, as well as the location of engines, rotation mechanisms and unbalanced loads in it, its center of mass is located below the geometric axis coinciding with axis 14.

The implementation of the invention

The inventive inertial propulsion device operates as follows. The motors 8, 10 transmit torque through the rotation mechanisms of the driven shafts 9, 11 to the unbalances 6, 7 shown in FIG. 5 and FIG. 6, which begin to rotate on axis 14 with a constant angular velocity w synchronously in opposite directions. For each unbalance during rotation, the centrifugal force F acts:

F = mw ² R,

where m is the mass of unbalance,

w is the angular velocity of its rotation,

R is the radius of rotation, that is, the distance from the axis of rotation to the center of mass of the unbalance.

The projection of the force F on the Y axis is mutually balanced, since it is directed opposite to each other, and doubled in the projection on the X axis, since it is directed in one direction. The force diagram is shown in FIG. 5. In the first half-period of unbalance rotation, the projection of centrifugal forces F _x acts in the direction of the X axis. Since the outer cylinder 1 rotates freely along the surface of the inner cylinder 2 in the direction of travel, the inertial propulsion device moves a distance S due to the rolling of the outer cylinder along the supporting surface . The work of centrifugal forces And in this case is determined by the formula:

или A=2F_xcpS,

or A = 2F _xcp S,

where F _xcp is the projection of the average centrifugal force for a half-period of rotation of unbalances,

S is the distance the mover has moved.

In the second half-cycle of rotation of the unbalances 6, 7, the centrifugal forces F are directed in the opposite direction from the direction of movement. If the outer cylinder 1 freely rotated in both directions on the surface of the inner cylinder 2, then the inertial propulsion device, due to the full symmetry of the forces acting on it, would have performed the same movement S in the opposite direction, and the propulsor made reciprocating movements relative to the starting point of movement. In this design, the rotation of the outer cylinder in the opposite direction from the direction of movement is limited by the locking mechanism 4. Therefore, in the second half-cycle, the work of centrifugal unbalance forces 6, 7 is not aimed at moving the propulsion device in the opposite direction, but at overcoming the moment of gravitational force acting on the inner cylinder 2.

A diagram of the acting forces is shown in FIG. 6.

Since the outer cylinder 1 is locked relative to the inner cylinder 2 in the second half-cycle, the centrifugal forces acting on the unbalances 6, 7 perform the work of turning the entire structure relative to the fulcrum of the outer cylinder on the supporting surface. While the moments of centrifugal forces, as well as the forces of gravity acting on unbalances of 6.7, are greater than the moment of gravity acting on the inner cylinder 2, which is an unbalance, the whole structure is rotated by a certain angle, but as soon as the moments are balanced, the rotation ends.

GL = 2FL _{3 1} + 2mgL ₂

G = Mg

where G is the force of gravity acting on the inner cylinder,

M is the mass of the inner cylinder,

m is the mass of unbalance,

g is the acceleration of gravity,

L ₁ - the shoulder of centrifugal force,

₂ L - shoulder gravity acting on the unbalanced mass,

₃ L - shoulder gravity acting on the inner cylinder

As a result of the rotation of the entire propulsion structure relative to the fulcrum, the center of mass of the inner cylinder 2 rises to a height Δh.

The work of centrifugal forces in the second half-cycle is spent on the accumulation of potential energy of the propulsion:

E = MgΔh,

where E is the potential energy accumulated during the second half-cycle,

g is the acceleration of gravity,

Δh is the height to which the center of mass of the inner cylinder was raised,

M is the mass of the inner cylinder.

As soon as the moment of gravity acting on the inner cylinder 2 becomes larger than the moments of forces acting on the unbalances 6, 7, the rotation of the entire propulsion structure relative to the fulcrum begins in the direction of movement along the X axis, and the accumulated potential energy E, according to the law of conservation of energy, begins go into the kinetic energy K:

E = K

wherein M _d - mass inertial mover,

V _x is the speed in the direction of the X axis.

In each half-cycle, the described processes are repeated.

Thus, the inventive inertial propulsion device, in the first half-cycle of rotation of the unbalances performs translational motion, and in the second period accumulates the energy of rotation of the unbalances in the form of potential energy, then passes into the kinetic energy of the translational motion. Due to the accumulation of energy in every second half-cycle of unbalance rotation, the efficiency of the propulsion increases. In addition, due to the simplification of the design, the compactness of the inventive inertial propulsion is achieved.
