The invention relates to the field of transport engineering, in particular can be used in the suspension vehicle.

Known shock absorber of a suspension containing the reservoir formed by the main pipe and installed coaxially it an extra tube, a piston fixed to the rod, the separator piston, a pump located between the piston and the dividing piston, valve, connecting rod cavity with the tank (patent RF №2072924, IPC 6 B60G 17/04).

A disadvantage of the known design is the damping of the oscillations by reducing the thrust force on the drive wheels when driving over bumps.

The closest technical solution, selected as a prototype, is the shock absorber of a suspension containing the reservoir formed by the main pipe and installed coaxially it an extra tube, a piston fixed to the rod, the separator piston, a pump located between the piston and the dividing piston, valve, connecting rod cavity with the tank, the pump is provided with two valves, one of which is through the passage in the pump housing, connects the cavity between the piston and the pump with the tank, and the other connects the cavity between the piston and the pump cavity between the pump and the dividing piston, and the pump is provided with a spring is ajknym disk with fixed therein at least one shaft, the working end is made from cut and communicates with the slot in the pump casing, in addition, valve, connecting rod cavity with the tank, connected to the cavity between the pump and the separator piston or cavity between the piston and the pump, while the rod end is installed to the upper spring-loaded piston with a hole, and the rod is fixed buffer (patent RF №2226157, IPC B60G 11/26, 2002).

A disadvantage of the known design is that the damping of the vehicle (including suspension), caused by microprofiles road, due to the expiration of the damping fluid through the throttling holes. This vibrational energy is transferred into heat energy shock absorber fluid [1], causing it to heat and when reaching a certain temperature to the abnormal conditions of the process in the absorber [1]. It is also known from the law of conservation of energy that energy does not arise out of nowhere. We conclude that the vibrational energy caused by microprofiles road, arises from the energy of the translational motion of the vehicle, thereby reducing it, which is equivalent to reducing the thrust force on the drive wheels.

The technical result is to reduce heat shock absorber fluid and the use of vibrational energy to drive the equipment the project vehicle.

The technical result is achieved in that the device for damping oscillations of a vehicle containing a shock absorber having a piston rod with a piston separating the inner portion of the upper and lower cavity, additionally performed two channels, and the channel connects the upper chamber of the shock absorber by line, which is connected with the first solenoid valve and the line connected to the control unit and slide through the channel made in the body of the spool, and the first electromagnetic valve connected to the line which is connected to the spool through a channel made in the body of the valve, and the lower channel connects the lower cavity of the shock absorber with the line, which is connected to the second electromagnetic valve and the line connected to the control unit and slide through the channel made in the body of the valve and the second solenoid valve connected to the line which is connected to the spool through a channel made in the body of the slide valve, the slide valve has a plunger located in the middle position due to the spring, and the movable electromagnet driven by a control unit, in addition, there is a line connecting two channel made in the body of the spool, with the entrance to the hydraulic motor, and also has a line connecting the two Kahn is La, made in the body of the spool, with the output of the motor, in addition, the hydraulic motor is driven with external devices.

Distinctive features of the prototype is that in the device for damping oscillations of the vehicle is additionally performed two channels, and the channel connects the upper chamber of the shock absorber by line, which is connected with the first solenoid valve and the line connected to the control unit and slide through the channel made in the body of the spool, and the first electromagnetic valve connected to the line which is connected to the spool through a channel made in the body of the valve, and the lower channel connects the lower cavity of the absorber by line, which is connected to the second electromagnetic valve and the line connected to the control unit and with the valve through a channel made in the body of the valve and the second solenoid valve connected to the line which is connected to the spool through a channel made in the body of the slide valve, the slide valve has a plunger located in the middle position due to the spring, and the movable electromagnet driven by a control unit, in addition, there is a line connecting two channel made in the body of the spool, with the entrance to the hydraulic motor, and also has claimed the al, connecting two channel made in the body of the spool, with the output of the motor, in addition, the hydraulic motor is driven with external devices.

Comparative analysis of the proposed solutions and selected as the prototype shows that the proposed device for damping oscillations of the vehicle allows to damp the vibrations through the use of vibrational energy to drive the equipment of the vehicle, thereby when driving on uneven increasing free thrust, reducing overall fuel consumption and heat shock absorber fluid [1].

The drawing shows a device for damping oscillations of the vehicle. The device consists of a shock absorber 1 having a shaft 2 with a piston 3, separating the inner part of the upper 4 and lower cavity 5, it executes two channels 6 and 7, with the upper channel 6 connects the upper cavity 4 of the absorber by line 8, which is connected with the first solenoid valve 9 and line 10 connected to the control unit 11 and the valve 12 through the channel 13, is made in the body of the spool 12, and the first solenoid valve 9 is connected to the line 14 which is connected to the valve 12 through the channel 15, is made in the case the spool 12, and the lower channel 7 connects the lower cavity 5 of the shock absorber 1 with highway 16, which is connected with the which the electromagnetic valve 17 and line 18, connected to the control unit 11 and the valve 12 through the channel 19, is made in the body of the spool 12, and the second electromagnetic valve 17 is connected to the line 20 which is connected to the valve 12 through the channel 21, is made in the body of the spool, the spool 12 has a plunger 22, which is in the middle position by the spring 23, and the movable electromagnet 24, driven by a control unit 11, in addition, there is a line 25 connecting the two channels 26 and 27 made in the body of the valve 12, with the entrance to the hydraulic motor 28, and also has a line 29 connecting the two channels 30 and 31 made in the body of the valve 12, with the output of the motor 28, in addition, the hydraulic motor 28 is driven external equipment.

Device for damping vibrations of the vehicle operates as follows. During movement of the vehicle when it hit a bump, the shock absorber 1 starts to be compressed, the rod 2 and the piston 3 displace the damping liquid from the bottom of the cavity 5. In the damping fluid is delivered under pressure through the channel 7, line 16, the solenoid valve 17, line 20 and channel 21 in the cavity between the valve body 12 and the plunger 22 by moving the plunger 22 and thereby opening the channels 13, 27, 30. At the same time damping fluid under pressure from line 16 enters the line 18 and the lock control 11, as a result, the control unit 11 supplies electric current to the electromagnetic valve 9, which is closed. Further damping fluid under pressure enters through the open channel 27 and the line 25 to the input of hydromotor 28, passing through it causes the gear to rotate with shafts running gear is removed torque to drive external equipment. From the hydraulic motor 28 damping fluid flows through line 29 and the channel 30 into the internal cavity of the valve 12 and then through the channel 13, line 10, 8, and channel 6 in the upper cavity 4. Another way damping fluid can't pass because the channels 19, 26, 31 are blocked by the plunger 22 and the channel 15 is blocked by the plunger 22 and the electromagnetic valve 9 due to the excess pressure in the line 18 compared to highway 10. When reverse motion of the piston movement of the shock absorber fluid is in flip, with the gear of the motor 28 to rotate in the same direction as before.

If the torque produced by the motor 28, is directed to the drive wheels, while reversing the roughness of the gear motor 28 to rotate in the opposite direction. For this purpose, when the reverse gear is engaged, the control unit 11 supplies electric current to electromagnet the e valves 9 or 17 in the reverse order, than was specified. In addition, when the differential pressure in lines 10 and 18, the control unit 11 shifts the plunger 22 of a movable electromagnet 24 by means of the electromagnetic field in the direction opposite to the displacement of the plunger 22 when the vehicle ahead. As a result, when the compression damping fluid is delivered under pressure from the lower cavity 5 through the channel 7, line 16, and 18 channel 19 (as the plunger 22 is displaced in the opposite direction) in the internal cavity of the valve 12. Then, through the channel 31 and highway 29 in the hydraulic motor 28, causing the rotation of the pinion in the opposite direction, through line 25 and channel 26 of the damping fluid is delivered into the internal cavity of the valve 12. From slide 12 of the damping fluid passing through the channel 15, line 14, the solenoid valve 9, line 8, and channel 6 in the upper cavity 4. When reverse motion of the piston movement of the shock absorber fluid is in flip, with the gear of the motor 28 to rotate in the same direction as before.

The workflow using the specified device is designed to absorb the energy of oscillations in the suspension, reduce fuel consumption and to increase traction when driving the vehicle over bumps, and lower the heat shock absorber fluid, thereby improving the living conditions of the Oia works shock absorber [1].
