Work process and the principle of the present invention are as follows:
Heavy engineering vehicle, during hauling operation, is uneven place when running to Active workings or road
Time or when bringing to a halt for some reason, evoke load-carrying frame weaving, make to be fixed on vehicle frame and interaxle energy regenerative vibration damping
Luffing damping vibration made by device 1, and first built-up piston 13 along cylinder barrel 12 slide downward, makes energy regenerative vibration damping
Device 1 cavity of resorption fluid is squeezed, the high-voltage oil liquid of vibroshock cavity of resorption, by the second of built-up piston 13
Bent road throttling oil duct, piston rod the second oil duct, the first high-pressure oil pipe 5 connect with the 5th high-pressure oil pipe 29,
Pressure jump is fed back to control device by the first pressure transducer 33 being installed on the first high-pressure oil pipe 5
42, control device 42 according to pressure jump value size, its one end of automatically delaying and the 5th high-pressure oil pipe 29
The opening time of the first electromagnetism check valve 23 connected, the damping dynamic stiffness of vibroshock cavity of resorption suitably increases,
Make the damping dynamic stiffness of vibroshock cavity of resorption with road conditions Automatic adjusument, reduce the frequency of vibration between vehicle frame and vehicle bridge
Rate and amplitude, can effectively protect vehicle frame to exempt from destruction；When the first electromagnetism check valve 23 is unidirectional with the 3rd electromagnetism
Valve 25 is opened simultaneously, and hydraulic oil the 3rd high-pressure oil pipe, the 7th high-pressure oil pipe 31 enter hydraulic motor 21,
Due to air bag 16 pressurized, gas enters Oil-gas Separation pressure balance type accumulator 22 by high-pressure air pipe
Air chamber 223, its elastic diaphragm 221 deforms, and makes the fluid pressure of liquid chambers increase, the part of liquid chambers
Highly pressurised liquid is also in hydraulic motor 21, and high-voltage oil liquid drives hydraulic motor 21 to drive 41 turns of electromotor
Dynamic generating, its electric current produced enters electric capacity 44 via DC/DC changer 43, and electric energy is filled by electric capacity 44
Enter in accumulator 45；Vibroshock epicoele oil liquid pressure reduces, and hydraulic motor 21 exports fluid, through the 8th
High-pressure oil pipe 32, the 4th high-pressure oil pipe 28, the 3rd electromagnetism check valve 25, the 6th high-pressure oil pipe 30,
Two high-pressure oil pipes 6, piston rod the first oil duct, the first bent road throttling oil duct of built-up piston 13 flow back to subtract
Shake device epicoele, owing to air bag 16 compression volume diminishes, and cylinder barrel 12 cavity of resorption when making built-up piston 13 move down
The volume that the volume of drain increases with cylinder barrel 12 epicoele is close, makes the fluid that hydraulic motor 21 is discharged
Vibroshock epicoele can be flowed back to completely, it is achieved circulating pressure oil stream generates electricity.
Built-up piston 13, along cylinder barrel 12 upward sliding, makes vibroshock epicoele fluid be squeezed, vibration damping
The high-voltage oil liquid of device epicoele, by the first of built-up piston 13 the bent road throttling oil duct, piston rod the first oil
Road, the second high-pressure oil pipe 6 connect with the 6th high-pressure oil pipe 30, be installed on the second high-pressure oil pipe 6
Pressure jump is fed back to control device 42 by two pressure transducers 34, controls device 42 according to pressure jump
Value size, opening of the second electromagnetism check valve 24 that its one end of automatically delaying is connected with the 6th high-pressure oil pipe 30
Opening the time, the damping dynamic stiffness of vibroshock epicoele suitably increases, make the damping dynamic stiffness of vibroshock epicoele with
Road conditions Automatic adjusument, reduces frequency and the amplitude of vibration between vehicle frame and vehicle bridge, can effectively protect vehicle frame to exempt from
Go to pot；When the second electromagnetism check valve 24 is opened with the 4th electromagnetism check valve 26 simultaneously, hydraulic oil is through
Three high-pressure oil pipe the 27, the 7th high-pressure oil pipes 31 enter hydraulic motor 21, and high-voltage oil liquid drives hydraulic motor
21 drive electromotor 41 to rotate generating, and its electric current produced enters electric capacity via DC/DC changer 43
44, electric energy is filled with in accumulator 45 by electric capacity 44；Vibroshock cavity of resorption oil liquid pressure reduces, hydraulic motor
21 outlet fluid through the 8th high-pressure oil pipe 32, the 4th high-pressure oil pipe 28, the 4th electromagnetism check valve 26, the
Five high-pressure oil pipe the 29, first high-pressure oil pipes 5, piston rod the second oil duct, the second bent road of built-up piston
Throttling oil duct flows back to vibroshock cavity of resorption, and owing to air bag 16 presses suffered oil pressure to reduce, highly pressurised liquid enters oil gas
The liquid chambers 222 of separating pressure balanced type accumulator 22, its elastic diaphragm 221 deforms, and makes air chamber 223
Gas pressure increase, the internal gas pressure of air bag 16 increases therewith, and air bag 16 volume becomes big, makes
The volume that when moving on built-up piston 13, the volume of cylinder barrel 12 epicoele drain increases with cylinder barrel 12 cavity of resorption
Close, the fluid making hydraulic motor 21 discharge can flow back to vibroshock cavity of resorption completely, it is achieved circulating pressure oil stream
Generating.
Heavy engineering vehicle during hauling operation, on more straight road surface close at the uniform velocity travel time, first
Fluid pressure fluctuation at pressure transducer 33 is less, and four electromagnetism check valves are all in closed mode, oil
The liquid chambers 222 of edema caused by disorder of QI tripping force balance type accumulator 22 and the 7th high-pressure oil pipe 31, hydraulic motor 21,
8th high-pressure oil pipe 32 connects, but by the first electromagnetism list between the 7th high-pressure oil pipe 31 and vibroshock upper and lower cavity
Block to valve 23 and the second electromagnetism check valve 24, by between the 8th high-pressure oil pipe 32 and vibroshock upper and lower cavity
Three electromagnetism check valves 25 and the 4th electromagnetism check valve 26 block, and hydraulic motor 21 does not works, Oil-gas Separation
The air chamber 223 of pressure balance type accumulator 22 and air bag 16 UNICOM, air bag 16 be in irregular repeatedly
Shrinking, expand less deformation state, the elastic diaphragm 221 of separating pressure balanced type accumulator 22 is in
The most protruding irregular relatively small deformation state.
