Specific embodiment
To make those skilled in the art be better understood from technical scheme, below in conjunction with the accompanying drawings and specific embodiment party
Formula elaborates to the present invention.
As shown in Figure 1 The embodiment provides a kind of electromechanical damping, including：Two supporting oil cylinders 20, variable
Pump 10, fuel tank 30, accumulator 40, pilot-actuated valve 50, proportional pressure reducing valve 70；Shockless bumper device 100.Specifically, two supporting oil
Cylinder 20 is arranged between the chassis of mobile device and pontic；Variable pump 10 is by fluid pressure line and the rodless cavity 21 of supporting oil cylinder 20
Connection, variable pump 10 are that supporting oil cylinder 20 provides supporting force；The rod chamber 22 of supporting oil cylinder 20 is connected with fuel tank 30；Accumulator 40
Rated pressure less than variable pump 10 rated pressure, accumulator 40 connected with the rodless cavity 21 of supporting oil cylinder 20 by fluid pressure line
It is logical；Pilot-actuated valve 50 is arranged between accumulator 40 and rodless cavity 21, and pilot-actuated valve 50 has makes rodless cavity 21 and accumulation of energy
What device 40 was blocked blocks position and makes the conduction position of rodless cavity 21 and the conducting of accumulator 40, and pilot-actuated valve 50 also has a left side
Pilot control chamber 60 and right pilot control chamber 80, are provided with guide's spring 81, rodless cavity 21 and right elder generation in left pilot control chamber 60
Lead control chamber 80 to connect；Proportional pressure reducing valve 70, which is arranged between rodless cavity 21 and left pilot control chamber 60；Wherein：Work as supporting
When oil cylinder 20 is not affected by impact, the hydraulic oil in right pilot control chamber 80 causes pilot-actuated valve 50 to be in and blocks position, and works as
When supporting oil cylinder 20 is impacted, left pilot control chamber 60 causes 50 switching-on position of pilot-actuated valve with guide's spring 81
Put, so that the hydraulic oil in rodless cavity 21 is entered in accumulator 40 by pilot-actuated valve 50；Shockless bumper device 100 includes microseism
Microseism cylinder body 101 is divided into a left side by cylinder body 101 and the microseism piston 102 being arranged in microseism cylinder body 101, microseism piston 102
Microseism chamber 103 and right microseism chamber 104, right microseism chamber 104 are connected with the rodless cavity 21 of supporting oil cylinder 20, left microseism chamber
103 are connected with fuel tank 30, are provided with microseism spring 105 in left microseism chamber 103.
Understood according to above-mentioned, the position of blocking residing for pilot-actuated valve 50 is determined by its two control chamber with conduction position, i.e.,
Left pilot control chamber 60 and right pilot control chamber 80, two control chamber are connected with rodless cavity 21 and proportional pressure reducing valve 70 respectively, are made
When proper mobile device travels on smooth-riding surface, the pressure of the hydraulic oil in rodless cavity 21 is steady, the right side connected with rodless cavity 21
Left guide's control that the pressure of the hydraulic oil in pilot control chamber 80 is provided more than 81 thrust of guide's spring and proportional pressure reducing valve 70
The pressure of the hydraulic oil in chamber processed 60, so that pilot-actuated valve 50 is in blocks position；And work as mobile device and travel on and jolt
During road surface, when supporting oil cylinder 20 is given a shock impact, impulsive force passes to the hydraulic oil in rodless cavity 21, and the pressure of hydraulic oil is fast
Speed raise, proportional pressure reducing valve 70 cause left pilot control chamber 60 in hydraulic oil proportional pressure increase, now, with guide
Under 81 force action of spring, so that pilot-actuated valve 50 is switched to conduction position from position is blocked, now, in rodless cavity 21
Hydraulic oil is entered in accumulator 40 by pilot-actuated valve 50, so that the pressure oil in rodless cavity Room 21 is gradually reduced,
The piston for holding oil cylinder 20 is moved down to alleviate impulsive force, just as guide's spring 81 is by compression.
Using the flowing of pressure oil come damping vibration, prior 2 points are the present invention：By the pressure in rodless cavity 21
Oil flows to accumulator 40 to play cushioning effect；Control pilot-actuated valve 50 blocking position and leading by proportional pressure reducing valve 70
Switch between logical position, so as to control the break-make of rodless cavity 21 and accumulator 40.So that mobile device can either be smooth
Road surface smooth-ride, can make pressure oil flowing on road surface of jolting again and play buffering work to shake by controlling pilot-actuated valve 50
With.
Understood according to above-mentioned, be when supporting oil cylinder 20 the reason for supporting oil cylinder 20 can play cushioning effect to mobile device
When being impacted, the pressure oil in rodless cavity 21 is exported or claims to be extruded so that the piston of supporting oil cylinder 20 is moved down, from
And buffering is played to impact endurance test shock, in said structure, on the one hand, the pressure oil in rodless cavity 21 enters right microseism chamber 104
In, on the other hand, the pressure oil in rodless cavity 21 is entered in accumulator 40, so that the pressure oil two-way in rodless cavity 21
Derive, and then make the piston of supporting oil cylinder 20 move down to play shock absorbing effect.Importantly, the microseism of the present invention
Buffer 100 in rodless cavity 21 pressure change reaction it is sensitiveer (coefficient of elasticity of microseism spring 105 can arrange it is less with
Improve the sensitivity of reaction), when supporting oil cylinder 20 is subject to less impact, the pressure oil in rodless cavity 21 initially enters right microseism
Chamber 104, so as to pass through microseism piston 102 so that microseism spring 105 compresses, so that less suffered by supporting oil cylinder 20
Impact endurance test shock is instantly obtained buffering, and when supporting oil cylinder 20 is subject to greater impact, pilot-actuated valve 50 can be just opened so that nothing
Pressure oil in rod cavity 21 enters accumulator 40, so that the larger impact endurance test shock that supporting oil cylinder 20 is subject to is eased.Cause
This says that shockless bumper device 100 can buffer less impact endurance test shock, and accumulator 40 can buffer larger impact endurance test shock, so as to
Electromechanical hybrid electro damping of the invention is made to can adapt to the situation of different impact endurance test shocks so that mobile device is on any road
Face can smooth-ride.
Preferably, pilot-actuated valve 50 is bi-bit bi-pass reversal valve.
Preferably, switch valve 90 is provided with the return line of variable pump 10 and accumulator 40.
Preferably, switch valve 90 is two-position two-way solenoid valve.
Above example is only the exemplary embodiment of the present invention, is not used in the restriction present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can be made respectively to the present invention in the essence and protection domain of the present invention
Modification or equivalent are planted, this modification or equivalent also should be regarded as being within the scope of the present invention.
