The invention relates to vehicles intended for use in complex terrain.
Known pulse propulsion for the vehicle with the transducer rotation of the inertial mass in a unidirectional linear motion and driven by two independent motors [RF Patent №2131059, IPC F03G 3/08].
The disadvantages of the known pulse propulsion is the design complexity and the presence of two independent engines.
Closest to the invention, the technical solution is Bouncing vehicle, comprising a housing and a base, attached to it by means of springs wheels and hopping impulse engine. Hopping pulse motor is a solenoid with a magnetic core-pusher [RF Patent №2259299, IPC B62D 57/02, bull. No. 24, 27.08.2005].
The disadvantages of the known Bouncing of the vehicle are large dynamic loads at the initial moment of the jump, due to the percussive action of the core-pusher when interacting with the soil, which is a vehicle.
The objective of the invention is the ability to reduce dynamic loads. This goal is achieved by the fact that in a vehicle, comprising a housing and a base, wheels and pulse propulsion, closed the prisoners on the basis pulse propulsion consists of an elastic force element, the impeller with variable eccentricity and the motor which drives the impeller, and the base rests on the wheels by means of Z-shaped supports with elastic elements, working in torsion.
The drive to the wheels through a Z-shaped transmission from the engine, located at the base.
Elastic force element is designed as a movable plate spring fixed at an angle to the base on the guides, with the possibility of complete cleaning of the inside of the case. Elastic strength member is able to rotate relative to the base.
The drawing shows the General appearance of the vehicle.
The essence of the invention. Based on 1 vehicle mounted housing 2, a motor 3, the pulse propulsion, consisting of the impeller 4 and the elastic force element 5 fixed to the rails 6. The impeller 4 is fixed on the axis with the possibility of radial displacement than is achieved by changing the eccentricity of the wheel 4. Elastic force element 5 is able to move along the rails 6. This changes its free length and rigidity of the protruding part. The basis of the vehicle based on wheel 7 through a Z-shaped support 8. Each Z-shaped support 8 its, upper end of the anchor is and to the base 1 through the elastic element 9, working in torsion. With one end of the elastic element 9 is rigidly fixed to the base 1, and the other on a support 8, which allows the support 8 to swing around the axis of the elastic element 9 at its curl. In addition, Z-shaped bearing allows mechanical drive installed on it wheels 7 from the engine 3. The actuator may be a chain or by using bevel gears, or in any other.
The vehicle operates as follows.
Movement on flat terrain with the help of the wheels 7.
The drive to the wheels 7 is supplied from the motor 3 through the Z-shaped support 8. When this torque can be sum up as to all the wheels simultaneously, and to separate from them. For changing the direction of movement of the wheel 7 can be rotated.
To overcome obstacles by jumping into the action introduces a pulse propulsion. For this purpose the guides 6 of the base 1 extends elastic force element 5 before contact with the ground on which the vehicle. Depending on the direction of further movement of the elastic force element 5 is rotated at a certain angle relative to the base 1. Depending on the required range of a single hop is changing the eccentricity of the impeller 4. The impeller is driven from the far East is the engine 3 and, coming in contact with the elastic force element 5, rejects it, thus pushes the vehicle from the ground. To reduce friction losses, the outer surface of the impeller 4, acting on the elastic force element 5 may be made in the form of a rolling bearing. The vehicle is detached from the support and jumps. When boarding the vehicle, the elastic elements 9 each support 8 and the elastic force element 5 performs the function of shock absorbers.
Driving a vehicle can be carried out on-Board computer. To improve the efficiency of the vehicle engine 3 can operate in intermittent mode only at the initial moment of the jump. Further flight is carried out with the engine switched off. Moreover, the vehicle engine can be either thermal or electric or any other kind, depending on the conditions.
Elastic force element 5 at the initial jump elastically deformed, thereby eliminating shock loads on the entire vehicle. The range of the vehicle can be varied by changing the degree of eccentricity of the impeller 4, or by adjusting the stiffness of the elastic force element 5. The change in the stiffness of the elastic force element 5 is displaced who eat it along the guides 6. This changes the free length of the elastic force element 5, and it is also possible to completely remove the elastic force element inside of the case to achieve the best terrain vehicle while moving on wheels.

SUBSTANCE: method for controlling machine for tilling land involves movement and contact of actuating elements of the machine with the soil. The actuating elements are moved a step forward and then stopped. Support keeps the actuating elements from recoiling when other actuating elements and the machine are moved and these movements are repeated for the required number of times and without increasing number of actuating elements and passage on the ground. The load of the wheels of the machine is adaptively reduced without their skidding. When tilling the soil, resistance of the moving actuating element to recoiling is increased or by supports, so that the propulsive force coincides with the required value, or by self rotation of the moving actuating element, turning it into a support-anchor. The actuating elements are moved along the machine to increase speed with little grabbing across - for increasing the width of grabbing, or combining them, thereby increasing the grabbing width. By shifting supports or restrictors, the stepping motion of the actuating elements is reversed. The stepping actuating elements are moved in succession or together depending on the working conditions. When there is differential drive of the actuating elements, the stepping sequence and the speed of motion is determined by the resistance of the actuating elements. Low resistance actuating elements are put in front of elements with high resistance and maintain the working order or protection when obstacles are encountered. The machine for tilling land has a mechanism for movement and lifting actuating elements. The machine also has detachable stepping actuating elements for tilling the land, supports and drives for longitudinal movement, as well as supports and drives for transverse movement of actuating elements. The drive for actuating elements has an oscillation source which is in form of one ball and socket joint or off-axis roller. The machine also has guide actuating elements. Detachable moving actuating elements are in form of a plough, ripper, paring plough, cultivator, bulldozer, grader, grubber, brush breaker, or some other actuating element with supports for generating propulsion force. The detachable actuating elements are mounted on sections of the step pathway. Actuating elements are installed with provision for rotation for adjusting the row spacing.

The used system is unbalanced with the center of masses coinciding in the static condition with the center of gravity of this system and with one of the ellipse focal points. The movement of the system is exercised by the successive step relocations in the moments of the impulse action of the inertial forces along the long axis of the ellipse of the maximal value disturbing force directed from the main focus point in the movement direction. The method of the controlled movement of the transport vehicle in the preset direction provides for utilization for production of the tractive effort of the propeller generating impulses of the inertial forces.
