The invention relates to mechanics and can be used in vehicles in order to transfer the load of the body on the suspension and the elimination of conditions of occurrence of fluctuations in the body during overcoming vertical irregularities of the road.

Known spring spring used to transfer the load of the body on the suspension of the vehicle, and to mitigate impacts and shocks transmitted from the suspension to the body while overcoming the vehicle vertical irregularities of the road, and consisting of an elastic element, one end of which is connected with the source of vibrations (suspension)and the other with the receiver oscillation (body).

The disadvantages of spring spring is that it when moving the suspension up transmits this movement to the body and thereby enables the formation of occurrence of the pulse energy is mass of the body, which is the main part of the mass of the entire vehicle, and the mass in this case is directly proportional to the derivative of the pulse energy. Also spring spring has a narrow operating range of the transmitted load in the mitigation of impacts and collisions. Thus, at low loads, the spring raises the body above its normal position and when the vibrations of the suspension is not compressed, and therefore not absorbs shocks and aftershocks, at high loads the spring lowers the body below the normal state is, fully compressed, and absorbs shocks and tremors.

The technical result of the claimed spring small resistance is to eliminate the conditions of oscillation of the body while overcoming the vehicle vertical irregularities of the road.

The applicant analogues of this device is unknown.

This technical result is achieved by the fact that the device is a spring of small resistance (see drawing)containing pneumonectomy 1, the discharge capacity 2, a compressor 3, a sensor 4 pressure difference between the discharge capacity of 2 and pneumonectomy 1, the tube 5 connecting the compressor 3 and the discharge capacity of 2, the tube 6 connecting pneumonectomy 1 and the discharge capacity of 2, the tube 6 connecting pneumonectomy 1 and the discharge capacity of 2, the unloading valve 7, the sensor 8 point With the connection of the springs with the receiver of the oscillations with respect to a connection of the springs with the vibration source, pneumonias 9 with the exhaust valve 10 and the intake valve 11, a tube 12, which connects the inlet valve 11 and the receiving tank 14, the tube 13 connecting the unloading valve 7 and the receiving tank 14, while pneumonectomy 1 through pipes 5 and 6 is additionally connected to the discharge capacity of 2 and a compressor 3, a sensor 4 pressure difference connected with pneumonectomy 1, loading and unloading capacity 2 to what Apana 7, and the position sensor 8 is connected to the compressor 3 and the discharge valve 7.

If you change the weight of the vehicle position sensor 8, if the point is below the normal position, includes a compressor 3, which blows air through a connecting tube 5 into the discharge capacity 2, where through the connecting tube 6, the air enters pneumonectomy 1, where increasing the air pressure raises the point C.

When the points in the normal position of the sensor 8 keeps the compressor off. The pressure in pneumomassage 1 and the discharge capacity becomes equal and normal. If the point is above the normal position, the sensor 8 opens the discharge valve 7, the pressure in pneumomassage 1 and the discharge vessel 2 is reduced and the point C is omitted.

When the points in the normal position of the sensor 8 holds the valve 7 closed. The position sensor 8 has enough inertia, i.e. at the operating frequency and equal amplitude fluctuations in the normal position of point C, the sensor 8 is not activated.

With a slight hesitation point And that meet the specified requirements, the motion of the point And up the pressure in pneumomassage 1 slightly increases and excess air through the connecting pipe 5 is discharged in the discharge container 2, and the motion that is key And down air again enters the spring 1. The discharge capacity is sufficient that the pressure points on the receiver remained virtually unchanged. Due to the fact that the air through the connecting tube 5 flows freely into the discharge vessel, the sensor pressure difference 4 between the tank 2 and pneumonectomy 1 when these vibrations to the opening of the valves 7 and 10 are not triggered. In all cases, these fluctuations valves 10 and 11 are open.

As soon as the oscillation amplitude point And goes beyond the slightest hesitation, the sensor differential pressure 4 under the excessive pressure in pneumomassage 1 necessarily during the movement of the point And opens up the unloading valve 7 and the valve 11 to the establishment of normal pressure in pneumomassage 1, simultaneously, through open valve 11 through the tube 12 the same amount of air receiving tank 14 enters pneumonias 9. After that, when the point a begins to move down, under pressure, the air from the discharge vessel 2 through the connecting tube 5 enters pneumonectomy 1, compensating for the loss of air through the discharge valve 7, while through the open valve 10 through the tube 13 into the discharge capacity 2 the quantity of air equal to released through the valve 7. Thus, when the impact of the wheel on the suspension height of the vehicle receives the pulse energy of the derivative of the mass which is the mass of the suspension. In addition, the resulting energy is transferred to the receiver and passed to pneumonectomy useful work. The resonant oscillation of the vehicle to prevent by opening or closing the valves 10 and 11.

Spring small resistance containing pneumonectomy, the discharge capacity of the compressor, gauge pressure difference between the discharge capacity and pneumonectomy, the tube connecting the compressor and the discharge capacity, the tube connecting pneumonectomy and discharge capacity, the discharge valve, the position sensor point of connection of the springs with the receiver of the oscillations with respect to the point of connection of the springs with the vibration source, pneumonias with exhaust and intake valves, the tube connecting the inlet valve and the receiving tank, a pipe connecting the discharge valve and the receiving container, and pneumonectomy through tubes is additionally connected with the discharge capacity and the compressor, the sensor differential pressure connected with pneumonectomy, the discharge capacity and the discharge valve, and a position sensor connected to the compressor discharge valve.
