Detailed description of the invention
With reference to the accompanying drawings, in conjunction with the embodiments, the built-in oil-pressure damper of high accuracy provided this utility model is with stepless
Adjustable damper valve, is described in detail.
Embodiment
The high accuracy stepless adjustable damper valve of built-in oil-pressure damper of the present embodiment, including the piston being sequentially connected with up and down
Bar 1, dynamic valve system, intermediate sleeve 9, operating valve system, piston valve system 20, dynamic valve system is mounted to intermediate sleeve 9 top, intermediate sleeve 9 and piston
The metal adapter sleeve of bar 1 end is threaded, and operating valve system is enclosed in intermediate sleeve 9 by end mechanism riveting, piston valve system 20 with
Intermediate sleeve 9 is threaded.This orifice valve the whole series valves system is positioned in the working cylinder 2 of vibroshock, and working cylinder 2 is divided into upper and lower two
Chamber, is moved up and down by piston rod 1 and drives valve to work.
Dynamic valve system includes upper end capping 5, adjusts thimble 7, electric magnet 8, movable valve plug 10, and movable valve plug 10 includes movable valve plug spring
The seat of honour 11, movable valve plug spring 12, movable valve plug spring lower seat 13, movable valve plug bottom valve system 14, dynamic thimble 17, dynamic thimble spring 16, on
End seal lid 5 and electric magnet 8 are assembled to outside intermediate sleeve 9 upper end, by piston rod 1 lower end metal adapter sleeve and intermediate sleeve 9 screw thread
Clamping, adjusts thimble 7 and movable valve plug 10 is assembled to intermediate sleeve 9 inner upper end, by the work in movable valve plug spring 12 and intermediate sleeve 9
Make the riveting of valve system to be encapsulated in intermediate sleeve 9, adjust thimble 7 and apply pretightning force by the movable valve plug spring seat of honour 11 to movable valve plug spring 12,
Dynamic thimble 17 can move up and down with servo valve system after powered up, and the dynamic dynamic thimble 17 of thimble spring 16 auxiliary resets.
Intermediate sleeve 9 top is divided into movable valve plug 10 to provide motion for guide space, and bottom is divided into operating valve system to provide fluid to lead to
Road, uniform 8 the fluid normal open holes of its sidewall, process screw thread for connecting metal adapter sleeve and the work of piston rod outside end and centre
Plug valve system 20, is encapsulated in dynamic valve system and the riveting of operating valve system inside intermediate sleeve bottom intermediate sleeve 9.
Operating valve system includes having normal open hole and dynamic thimble 17 to seal in the middle of excessive valve seat 18 and float valve 19, excessive valve seat 18
Hole, normal open hole allows oil gang up movable valve plug 10 top, it is ensured that movable valve plug 10 moves accurately and reliably, and dynamic thimble 17 seals Kong Dangdong valve
When core 10 moves, fluid string ensures that excessive valve seat 18 oil pressure is consistent outside excessive valve seat 18, improves Adjustment precision；Separately cross bottom valve
Seat uniform 8 damping force normal open holes, 18 ends, when no power, upper and lower cavity fluid is by producing damping force, is adjusting thimble 7 He
Effect low suspension valve 19 lower end of movable valve plug spring 12 compresses with enclosed mechanism and seals, and upper surface compresses close with excessive valve seat 18
Envelope, intermediate sleeve 9 lower end is connected with piston valve system 20 by screw thread, and whole valve body is inserted in the working cylinder of vibroshock, electric magnet 8
It is connected with controller ECU by two lines.
No power work process: electric magnet 8 no power, movable valve plug 10 is motionless, and excessive valve seat 18 and float valve 19 compress close
Envelope, when piston rod 1 is pulled up, working cylinder 2 epicoele fluid enters excessive valve seat 18 by intermediate sleeve 9 sidewall fluid normal open hole
Normal open hole, fluid through float valve 19 inner chamber to piston valve system 20 generation recovery damping force；The working cylinder when piston rod 1 compresses
2 cavity of resorption fluid pass through this passage reverse flow, produce recovery damping force, and flow channel is shown in Fig. 2.
According to the difference of electric current, when electric magnet 8 produces different magnetic force, magnetic force overcomes movable valve plug spring 12 pre-compression force,
Movable valve plug 10 can move up, and now moves thimble 17 and excessive valve seat 18 all will move upward, and fluid is through the stream of float valve 19
Logical area increases, and therefore damping can reduce.
Energising work process: electric magnet 8 is energized, and movable valve plug 10 upwards moves, the gap of excessive valve seat 18 and float valve 19 increases
Adding, when piston rod 1 stretches, working cylinder 2 epicoele fluid arrives excessive valve seat 18 He by behind intermediate sleeve 9 sidewall fluid normal open hole
The gap of float valve 19, working cylinder 2 epicoele hydraulic oil promotes float valve 19 to produce gap with riveting sealing simultaneously, and fluid passes through, and produces
Oil generation liquid recovery damping force, oil passage is shown in Fig. 2, and when electric magnet 8 is energized, and piston rod 1 compresses, working cylinder 2 cavity of resorption fluid is from mistake
The gap of bottom valve seat 18 and float valve 19 enters intermediate sleeve 9 sidewall fluid normal open hole, this hole enter the epicoele of working cylinder, produces
Compression damping power, oil passage is shown in Fig. 3.
The most built-in oil-pressure damper is with stepless adjustable damper valve upper end by O I 3, O II 4, and oil removal is close
Envelope, lower end is sealed by O IV 15 oil removal；Adjustment thimble 7 is carried out oil removal sealing by O III 6；Motion portion after oil removal sealing
Part adjusts accurately and reliably and the life-span is long.
