Description

one

This invention relates to vehicles, in particular to wheeled propulsive engines.

Wheeled engines are known, consisting of an axis with two disks fixed to them, having a cylindrical bearing surface parallel to the axis. The side planes of such disks coincide with the plane of rotation.

A disadvantage of the known wheel thrusters is that the movement of the vehicle is carried out only by frictional forces between the disks and the ground, and in soft soil, where shear strength is low, they have low permeability.

The purpose of the invention is to increase the permeability.

This is achieved by the fact that the disks are set obliquely to the axis mirror-image relative to each other.

FIG. 1 shows a sinusoidal propulsion device, front view; in fig. 2 - the propeller and its raceways, top view.

A sinusoidal propulsor consists of a smallpox 1, on which two disks 2 and 3 are fixed, having a cylindrical rolling bearing surface parallel to axis 1, which passes through the geometric center of this cylinder. The disks 2 and 3 are set obliquely to the axis at identical angles mirroring one with respect to the other, with the intersection line of the lateral 4 and 5 planes of the disks 2 and 3 perpendicular to the axis i, therefore

the lateral 4 and 5 planes of the disks 2 and 3 are ellipses, at the price-ipe which passes the axis 1. The small axes of these ellipses are parallel and the large ones intersect, and the intersection point is equally removed from the centers of both ellipses.

When moving along a solid rpyniy, the propeller moves due to frictional forces alone between the bearing surfaces of disks 2 and 3 and soil 6, as with a conventional wheeled propulsion device. In this case, both rolling tracks in the plan have the form of sinusoidally curved ribbons 7 and 8 with a width of 1 / equal to the length of the contact line, each sinusoidal tape (for example, 7) being a mirror image of the other (11, 1.8).

When driving on soft ground, the disks 2 and 3 under the action of the weight of the vehicle Q, applied to the axis 1, of the external torque, are deepened into

soil 6 on the value of it. Then each raceway; will have width B greater than /. In this case, in addition to the friction forces between the onopiioi surface of the disks 2 and 3 and the ground 6 pyvl after additional pulling forces, you have the following forces directed backwards towards the direction of movement and upwards, which are resultant force vectors K., perpendicular These forces support the forward and upward movement, creating an additional useful effect, provided that the depth of penetration h does not exceed the radius of the cylindrical supporting surface of the disks R.

Subject matter

A sinusoidal propulsion vehicle, containing an axis with two fixed disks on it, having a cylindrical bearing surface parallel to the axis, characterized in that, in order to increase the permeability, the disks are mounted inclined to the axis mirror-image relative to each other.
