When generating relative motion between vehicle frame and axle, piston can generate accordingly or the movement of up or down；Piston to
Upper shift motion is extension stroke, and the stroke that piston moves down is compression travel.The hydraulic oil in hydraulic cylinder 3 can pass through at this time
Resistance trimming section, frequency modulation section, single turbine energy regenerating section between A hydraulic fluid ports, B hydraulic fluid ports, and then lower bunker 6 is flowed to from upper bunker 4, or
Upper bunker 4 is flowed to from lower bunker 6.
Due to the viscous effect of hydraulic oil in cylinder body, when hydraulic oil flows through resistance trimming section, the capillary that works in resistance trimming section
Damping can be generated to the flowing of hydraulic oil, to form the damping moved to piston；The size of the damping is passed through by control system
The configuration S of solenoid valveRnControl, and then realize the resistance trimming of resistance trimming section；
When hydraulic oil flows through frequency modulation section, change the configuration S of solenoid valve by control systemmn, then adjustable vibration-damper
System frequency, and then realize the frequency modulation of frequency modulation section；
When hydraulic oil passes through single turbine energy regenerating section, passed through from M three-way pipes according to the flow direction of hydraulic oil or hydraulic oil
Cross check valve V3, turbine T, check valve V4The lower bunker 6 of flow direction, while the G power generations of turbine T drawing generators, realize shaking for extension stroke
Swing energy consumption recycling；Or hydraulic oil passes through check valve V from lower bunker 65, turbine T, check valve V6Flow to M three-way pipes, while turbine T
The vibration energy-dissipation recycling of compression travel is realized in drawing generator G power generations；It is irretrievable just to solve vibration energy-dissipation for we in this way
Problem.
Now the present embodiment is described further by following three points.
1, the operation principle about single turbine energy regenerating section
When hydraulic oil needs flow to N three-way pipes from M three-way pipes, piston moves up, and this trip is extension stroke, because
Check valve V5、V6Cut-off effect, hydraulic oil be merely able to from M three-way pipes pass through check valve V3, turbine T, check valve V4The lower oil of flow direction
Storehouse 6；Hydraulic oil pushes the wheel rotation of turbine T, the G power generations of turbine T drawing generators to realize the vibration energy-dissipation of extension stroke simultaneously
Recycling.
When hydraulic oil needs flow to M three-way pipes from N three-way pipes, piston moves down, and this trip is compression travel, because
Check valve V3、V4Cut-off effect, hydraulic oil be merely able to from N three-way pipes pass through check valve V5, turbine T, check valve V6Flow to M tri-

It can recycling.
2, about resistance trimming section, the order of connection of frequency modulation section, single turbine energy regenerating section
Resistance trimming section, frequency modulation section, the order of connection of single turbine energy regenerating section are other than according to being linked in sequence of such as Fig. 2, also
It can be connected according to frequency modulation section, single turbine energy regenerating section, resistance trimming section, it is of course also possible to according to single turbine energy regenerating section, adjust
Resistance section, frequency modulation section etc. are linked in sequence.
3, the title about " single turbine recover energy and R formulas vehicle shock absorber of connecting "
In the title of " single turbine recover energy and R formulas vehicle shock absorber of connecting ", first in " and series connection "
" simultaneously " indicate that resistance trimming section is adjusted with parallel capillary, second " string " indicates that frequency modulation section is adjusted with tandem capillary.Its " R
The meaning that formula " indicates is as follows：
In the resistance trimming section of capillary, with capillary R8, R4, R2, R1 and its corresponding solenoid valve control system control
Under mode that the resistance (Resistance) of damper is adjusted.Its main feature is that：Other than hydraulic cylinder body, according to capillary
Resistance (Resistance) characteristic of pipe, by the multichannel of in parallel (or series connection) (can be four tunnels can also four tunnel of right and wrong) capillary
Pipe according to specific parameter (such as：The flow resistance etc. of hydraulic oil under area or length or some operating mode) according to certain
Rule (such as：The binary coding rule of 8421 equal ratios or other equal ratios or non-equal ratio are regular) it arranges, pass through control
System is controlled to achieve the purpose that adjust damping to the solenoid valve of corresponding capillary.The above is exactly in resistance trimming section
The meaning of " R formulas ".
In frequency modulation section, because the structure that we adjust frequency by capillary adjusts damping in the way of with above-mentioned capillary
Structure has many similarities with mode, so we, which will utilize capillary and solenoid valve to reach, adjusts the intrinsic frequency of damper system
The mode of rate is also referred to as " R formulas ".It is as follows in the meaning specific explanations of frequency modulation section, " R formulas "：
In the frequency modulation section of capillary, with capillary m8, m4, m2, m1 and its corresponding solenoid valve control system control
Under mode that damper system intrinsic frequency is adjusted.Its main feature is that：Other than hydraulic cylinder body, capillary caliber is utilized
Its resistance (Resistance) small characteristic when big, according to the capacity characteristic of capillary, the multichannel by series connection (or in parallel) (can
Tetra- tunnels Yi Shi can also four tunnel of right and wrong) capillary according to specific parameter (such as：Area or length or volume etc.) according to
Certain rule (such as：The binary coding rule of 8421 equal ratios or other equal ratios or non-equal ratio are regular) it arranges, pass through
Control system to the solenoid valve of corresponding capillary controlled to reach by adjust the quality of the hydraulic oil for participating in oscillation into
And achieve the purpose that adjust damper system intrinsic frequency.
When as long as damper has any one meaning in above-mentioned two " R formulas " meaning, it is known as R formulas by us
Damper or R formula vehicle shock absorbers.In R formula dampers, when existing capillary resistance trimming section also has capillary frequency modulation section,
Resistance trimming section, the way of frequency modulation section capillary can be equal, can not also wait.The capillary of R formula dampers removes and is processed into " M " shape
The other shapes such as helically shaped, serpentine shape can also be processed outside.These types of shape is only specific listed several shapes,
Many shapes can also be set out in practical application, it can be depending on specific requirement be flexible.
In addition, in R formula dampers, how carefully capillary is not necessarily intended to, and so-called refers to carefully just that hydraulic oil flows through capillary
It will produce resistance when pipe；That is, the capillary described in us is exactly hydraulic oil will produce when flowing through resistance oil pipe or
Oil circuit.
As described above, the utility model can be realized preferably.
The embodiment of the utility model is simultaneously not restricted to the described embodiments, other are any without departing from the utility model
Changes, modifications, substitutions, combinations, simplifications made by under Spirit Essence and principle, should be equivalent substitute mode, are included in
Within the scope of protection of the utility model.
