Description

The invention relates to vehicles intended for use in difficult terrain.

Known pulse propulsion for a vehicle with a converter of rotation of inertial masses in unidirectional linear motion and driven by two autonomous engines [RF Patent No. 2131059, IPC F03G 3/08].

The disadvantages of the known pulsed propulsor are the design complexity and the presence of two independent engines.

Closest to the invention, the technical solution is a jumping vehicle, comprising a housing and a base, with wheels mounted on it by means of springs and a jump pulse engine. Hopping pulsed motor is a solenoid with a magnetic core-pusher [RF Patent No. 22259299, IPC B62D 57/02, bull. No. 24, 08/27/2005].

The disadvantages of the known jumping vehicle are large dynamic loads at the initial moment of the jump, due to the impact of the core-pusher when it interacts with the ground on which the vehicle is located.

The objective of the invention is to provide opportunities to reduce dynamic loads. This goal is achieved by the fact that in a vehicle including a housing and a base, wheels and an impulse mover fixed to the base, the impulse mover consists of an elastic power element, an impeller with variable eccentricity and an engine driving the impeller, and the base rests on the wheels with help of Z-shaped supports with elastic elements working on torsion.

The drive to the wheels is through a Z-shaped gear from an engine located on the base.

The elastic power element is made in the form of a movable leaf spring fixed at an angle to the base on the rails, with the possibility of its complete cleaning inside the case. The elastic force element has the ability to rotate relative to the base.

The drawing shows a General view of the vehicle.

SUMMARY OF THE INVENTION On the basis of the vehicle 1, a housing 2, an engine 3, a pulse propulsion device consisting of an impeller 4 and an elastic force element 5 fixed in the guides 6 are mounted. The impeller 4 is mounted on the axis with the possibility of radial displacement, thereby achieving a change in the eccentricity of the wheel 4. The elastic force element 5 has the ability to move along the guides 6. This changes its free length and rigidity of the protruding part. The base of the vehicle is supported on wheels 7 through Z-shaped supports 8. Each Z-shaped support 8 is fixed with its upper end to the base 1 through a torsion-resistant elastic element 9. Moreover, one end of the elastic element 9 is rigidly fixed to the base 1, and the other to the support 8, which allows the support 8 to swing around the axis of the elastic element 9 when it is twisted. In addition, the Z-shaped support makes it possible to carry out the mechanical drive of the wheel 7 mounted on it from the engine 3. The drive can be chain either using bevel gears or other.

The vehicle operates as follows.

Driving on flat terrain occurs using wheels 7.

The drive to the wheels 7 is carried out from the engine 3 through the Z-shaped supports 8. In this case, the torque can be applied to both all the wheels simultaneously, and to individual ones. To change the direction of movement of the wheel 7 can be rotated.

To overcome obstacles by a jump, an impulse mover is introduced into the action. To do this, along the guides 6 from under the base 1 extends the elastic power element 5 until it comes into contact with the ground on which the vehicle is located. Depending on the direction of further movement, the elastic power element 5 is rotated by a certain angle relative to the base 1. Depending on the required range of a single jump, the eccentricity of the impeller 4 changes. The impeller is set in motion from the engine 3 and, coming in contact with the elastic power element 5, deflects it, thereby repels the vehicle from the ground. To reduce friction losses, the outer surface of the impeller 4, acting on the elastic force element 5, can be made in the form of a rolling bearing. The vehicle breaks off the support and makes a jump. When the vehicle is landing, the elastic elements 9 of each support 8 and the elastic power element 5 act as shock absorbers.

The vehicle can be controlled by the on-board computer. To increase the efficiency of the vehicle, the engine 3 can operate in intermittent mode only at the initial moment of the jump. Further flight is carried out with the engine turned off. Moreover, the engine of the vehicle can be either thermal, or electric, or any other kind, depending on operating conditions.

The elastic force element 5 at the initial moment of the jump is elastically deformed, thereby eliminating shock loads on the entire vehicle. The flight range of the vehicle can vary by changing the degree of eccentricity of the impeller 4 or by adjusting the stiffness of the elastic power element 5. The stiffness of the elastic power element 5 is changed by moving it along the guides 6. In this case, the free length of the elastic power element 5 changes, and it is also possible to completely remove elastic power element inside the body to achieve better cross-country ability of the vehicle when driving on wheels.
