Detailed description of the invention
nullEmbodiment: a kind of dual tube shock absorber,It is characterized in that,Including black box (1)、Piston rod (2)、Shell (3)、Middle cylinder (4)、Inner casing (5)、Check valve (6)、Piston (7)、Valve seat (8)、Shuttle valve (9)、Compression valve assembly (10)、Rubber bushing assembly (11),It is provided with piston rod (2) through black box (1),One of piston rod (2) is equipped with check valve (6),This head of described piston rod (2) and check valve (6) periphery are equipped with one of piston (7),This head of described piston rod (2) and check valve (6) and piston (7) periphery are provided with inner casing (5),Inner casing (5) periphery is provided with middle cylinder (4),Middle cylinder (4) periphery is provided with shell (3),The other end of piston (7) is sequentially provided with valve seat (8)、Shuttle valve (9)、Compression valve assembly (10)、Rubber bushing assembly (11).
Principle illustrates as follows:
When automobile turning along with the rotation of steering wheel, the angle of turn sensor on steering wheel sends parameter, the parameter of vehicle speed sensor, has master controller to process to amplifier result, and amplifier is to servo valve instruction.
Closing all passages of amortisseur inner carrier cylinder, locked piston rod, between wheel and vehicle body, amortisseur becomes support member.Stop spring-compressed, overcome the weight that centrifugal force offsets.Therefore vehicle body is controlled with the distance (vehicle body sinking) on ground.
Due to left and right shock absorber piston cylinder pathway closure, lock piston is after death.When due to after weight offset support spring release propulsive thrust also locked by piston lever of reducer.(vehicle body thrust upwards) keeps vehicle body to cross curved front attitude turning.
Operation principle according to vibroshock, vehicle shock absorber has been improved by we.
Amortisseur internal structure is made improvements, also can coordinate amortisseur servo valve, improve amortisseur performance.Reaching comfortable and handling, the safety of bend improves.
Amortisseur servo valve passes through direction sensor, vehicle speed sensor, displacement transducer, braking sensor, according to different road surfaces, different speed, bend etc., provides different parameters by servo valve amplifier.
The effect of amortisseur servo valve:
Automobile is crossed vehicle body in the process of hollow and is sunk.Become the attitude of double swerve.Reach the solution of the attitude of balance:
Cross hollow and cause the genetic analysis rocked:
Supporting wheel with tare is spring.Because the weight=vehicle body of the compression distance=vehicle body of spring and ground level.
Impulsive force when hollow crossed by automobile time, the compression distance of spring produces change.Support the power of vehicle body also in change.It is the quality decision according to amortisseur control spring function that control impulsive force and vehicle body rock size.
In common amortisseur:
1. partial compression valve and rebuilt valve composition, damping is fluid, and by valve block, flexible and gap length, produces power.
2. amortisseur is according to different automobile types, the requirement of different vendor, arranges damping force.
3. not individually for the setting crossing hollow parameter.
Therefore a lot of vehicle rocking on hollow road, the performance of size degree and amortisseur has relation.
Solution:
Automobile comfort level: this amortisseur servo valve has real-time guiding mechanism, by displacement transducer, the extension distance of detection spring.Calculate the decompression of spring supporting vehicle body.Provide parameter.By amortisseur servo valve.Adjust pressure in amortisseur and have piston rod counterbalance spring because crossing the support force of hollow, play maintenance car body balance.Reach the effect of balance.
Bend crossed by automobile: when automobile is crossed curved, the effect of centrifugal force.Body gesture seriously offsets, and have impact on that automobile is handling and safety.
Bend body sway genetic analysis:
Steering wheel rotation when crossing curved, tire can produce a drift angle and then produce steering force, and this strength acts on roll center and center of gravity, then leads to tare transfer.Strengthen vehicle body to produce to roll along with the increase of drift angle and the transfer of tare.
When crossing bend, vehicle body supports spring along with the increase of speed Yu centrifugal force with wheel, and decrement increases, and causes spring to shorten.The distance on vehicle body and ground reduces (weight=vehicle body of the compression distance=vehicle body of spring and ground level), when crossing bend, effect due to centrifugal force, after tare offsets, the support spring-compressed of another side, (amount of spring compression=weight) needs release, and therefore the propulsive thrust of spring raises the distance of wheel and vehicle body.The curved attitude of mistake formed.At this moment automobile is handling and poor stability.Speed controls bad.Vehicle accident can be had time serious.
Solution:
When automobile turning along with the rotation of steering wheel, the angle of turn sensor on steering wheel sends parameter, and the parameter of vehicle speed sensor has master controller to process to amplifier result, and amplifier is to servo valve instruction.
Close all passages of amortisseur inner carrier cylinder, locked piston rod.Between wheel and vehicle body, amortisseur becomes support member.Stop spring-compressed, overcome the weight that centrifugal force offsets.
Therefore vehicle body is controlled with the distance (vehicle body sinking) on ground.
Due to left and right shock absorber piston cylinder pathway closure, lock piston is after death.When due to after weight offset support spring release propulsive thrust also locked by piston lever of reducer.By vehicle body thrust upwards, keep vehicle body cross curved before attitude.
Example: according to the technical parameter of amortisseur servo valve as voltage 12V, maximum current 1.8A rated pressure 250bar, as system pressure 250bar, piston diameter 30mm, during diameter of piston rod 24mm.
Show that cavity of resorption piston compressing area be 4.52 square centimeters of epicoele piston areas is 4.93 square centimeters according to hydraulic principle radius x radius x3.14=area.
Drawing according to data above, 1130 kilograms of maximum recuperabilities of piston rod locked maximum, force support force 1232 kilograms change piston diameter can draw different maximum support power.
The diameter changing piston rod can draw different recuperabilities.
Reduce braking distance:
Amortisseur on market is by actually used experience.Performance quality can affect braking distance.Solution;
When braking sensor detects that automobile processor when braking sends the adjustment amortisseur damping of instruction amortisseur servo valve and adds big wheel earth-grasping force.
