Preferably, described second damping hole 503 is two with described 4th damping hole 503 '.
The specific works principle of the present invention is as follows:
nullWhen the cylinder body of the first cylinder chamber 20 of the first oil gas damping unit 1 shrinks relative to the cylinder body of the first hydraulic oil cylinder chamber 10，The volume that the volume that first hydraulic oil cylinder chamber cavity of resorption 102 reduces increases more than the first hydraulic oil cylinder chamber epicoele 101，Therefore hydraulic oil is flowed to the first cylinder chamber's cavity of resorption 203 and the first hydraulic oil cylinder chamber epicoele 101 by the first hydraulic oil cylinder chamber cavity of resorption 102，Now the first check valve 502 is opened，When the cylinder body of first piston 30 and the first cylinder chamber 20 moves downward relative to the cylinder body of the first hydraulic oil cylinder chamber 10，The damping force that first piston 30 and the first cylinder chamber 20 are subject to is less，This is equivalent to the effect of the spring in traditional suspension，Flowed to the second hydraulic oil cylinder chamber epicoele 101 ' and the second hydraulic oil cylinder chamber cavity of resorption 102 ' of the second oil gas damping unit 2 by the section hydraulic oil of the first hydraulic oil cylinder chamber cavity of resorption 102 with valvular oil pipe 3 and the first oil gas damping unit 1 and the first hydraulic oil cylinder chamber epicoele 101 simultaneously，Pressure in second oil gas damping unit 2 is increased，So can reduce the "Left"-deviationist of vehicle thus ensure lateral stability.nullWhen the cylinder body of the first cylinder chamber 20 of the first oil gas damping unit 1 stretches relative to the cylinder body of the first hydraulic oil cylinder chamber 10 when，The volume that the volume that first hydraulic oil cylinder chamber cavity of resorption 102 increases reduces more than the first hydraulic oil cylinder chamber epicoele 101，Therefore hydraulic oil is by first cylinder chamber's cavity of resorption 203、First hydraulic oil cylinder chamber epicoele 101 flows to the first hydraulic oil cylinder chamber cavity of resorption 102，Now the first check valve 502 is closed，When the cylinder body of first piston 30 and the first cylinder chamber 20 moves upward relative to the cylinder body of the first hydraulic oil cylinder chamber 10，The damping force that first piston 30 and the first cylinder chamber 20 are subject to is bigger，This is equivalent to the amortisseur effect in traditional suspension，Flowed to the first hydraulic oil cylinder chamber epicoele 101 and the first hydraulic oil cylinder chamber cavity of resorption 102 of the first oil gas damping unit 1 by the section hydraulic oil with valvular oil pipe 3 and the second oil gas damping unit 2 second hydraulic cylinder lower cavity oil and the second hydraulic jack epicoele simultaneously，Pressure in first oil gas damping unit 1 is increased，So can reduce the Right deviation of vehicle thus ensure lateral stability.
The concrete control process of the present invention is as follows:
(1), the compression travel of mixed connection formula oil vapor damping device.
As a example by the first oil gas damping unit 1, when the cylinder body of first piston 30 and the first cylinder chamber 20 shrinks relative to the cylinder body of the first hydraulic oil cylinder chamber 10, the cylinder body of the first cylinder chamber 20 moves downward, owing to the volume of the minimizing of the first hydraulic oil cylinder chamber cavity of resorption 102 is more than in the first hydraulic oil cylinder chamber epicoele 101 volume increased, so time the first hydraulic oil cylinder chamber cavity of resorption 102 in hydraulic oil compressed and moved to both direction: one is to flow to first cylinder chamber's cavity of resorption 203 by the first damping hole 501 and the first check valve 502, owing to the pressure of the hydraulic oil in first cylinder chamber's cavity of resorption 203 increases by the first floating piston 201, compression first cylinder chamber's epicoele 202 makes the volume of noble gas reduce further, the i.e. volume of nitrogen reduces, pressure in first cylinder chamber's epicoele 202 increases；Two is to flow to the first hydraulic oil cylinder chamber epicoele 101 by the second damping hole 503.
Hydraulic oil can produce damping force when flowing through first damping hole the 501, first check valve 502 and the second damping hole 503, this process, owing to first damping hole the 501, first check valve 502 and the second damping hole 503 open wide simultaneously, it is bigger that it flows through area, therefore flow velocity when hydraulic oil flows through first damping hole the 501, first check valve 502 and the second damping hole 503 is relatively low, and its damping force produced is the most relatively small.When hydraulic oil in first cylinder chamber's cavity of resorption 203 compresses the nitrogen in first cylinder chamber's epicoele 202, suppressing elastic force produced by the gas in power main pressured contracting the first cylinder chamber epicoele 202 of the first cylinder chamber 20 motion, it functions as the flexible member-spring in conventional suspension.
Additionally, on the whole when the first oil gas damping unit 1 is compressed, by flowing to the second hydraulic jack epicoele and second hydraulic cylinder lower cavity oil of the second oil gas damping unit 2 with the section hydraulic oil of valve oil pipe 3 and the first hydraulic cylinder lower cavity oil of the first oil gas damping unit 1 and the first hydraulic jack epicoele, pressure within second oil gas damping unit 2 is increased, so can reduce the "Left"-deviationist of vehicle thus ensure lateral stability.
(2), the stretching travel of mixed connection formula oil vapor damping device.
As a example by the first oil gas damping unit 1, when the cylinder body of first piston 30 and the first cylinder chamber 20 is upheld relative to the cylinder body of the first hydraulic oil cylinder chamber 10, then the hydraulic oil in the first hydraulic oil cylinder chamber epicoele 101 is compressed, and forces the hydraulic oil in the first hydraulic oil cylinder chamber epicoele 101 to be flowed to the first hydraulic oil cylinder chamber cavity of resorption 102 by the second damping hole 503.The volume increased due to the first hydraulic oil cylinder chamber cavity of resorption 102 is more than the volume that the first hydraulic oil cylinder chamber epicoele 101 reduces, therefore the hydraulic oil in first cylinder chamber's cavity of resorption 203 flows to the first hydraulic oil cylinder chamber cavity of resorption 102 (now the first check valve 502 is closed) also by the first damping hole 501.Again because of the hydraulic oil in first cylinder chamber's cavity of resorption 203 because first hydraulic oil cylinder chamber cavity of resorption 102 volume increase and by the gas compression in first cylinder chamber's epicoele 202 so that enter the first hydraulic oil cylinder chamber cavity of resorption 102.
By above-mentioned drawing process: owing to the first check valve 502 is closed in stretching travel, the damping force therefore produced is greater than the damping force in compression travel, the most just meet oil gas antivibrator and produce the requirement of asymmetric damping force when effect.The damping force little spring effect be equivalent in traditional suspension during compression, damping force bigger during stretching can decay vibration, is equivalent to the effect of vibroshock in traditional suspension.
Additionally, on the whole when the first oil gas damping unit 1 is stretched, the first hydraulic oil cylinder chamber epicoele 101 and the first hydraulic oil cylinder chamber cavity of resorption 102 of the first oil gas damping unit 1 is flowed to by the section hydraulic oil of the second hydraulic oil cylinder chamber cavity of resorption 102 ' with valvular oil pipe 3 and the second oil gas damping unit 2 and the second hydraulic oil cylinder chamber epicoele 101 ', pressure within first oil gas damping unit 1 is increased, so can reduce the Right deviation of vehicle thus ensure lateral stability.
nullNeed exist for special instruction be，First piston 30 and the second piston 30 ' respectively in corresponding first hydraulic oil cylinder chamber 10 and the second hydraulic oil cylinder chamber 10 ' on、Lower motion,Make the first hydraulic oil cylinder chamber cavity of resorption 102、The hydraulic oil of first cylinder chamber's cavity of resorption 203 reciprocally passes through the first damping hole 501 and the first check valve 502 under the effect of pressure reduction,Second hydraulic oil cylinder chamber cavity of resorption 102 '、The hydraulic oil of second cylinder chamber's cavity of resorption 203 ' reciprocally passes through the 3rd damping hole 501 ' and the 3rd check valve 502 ' under the effect of pressure reduction,The hydraulic oil with pressure reduction each respectively flows through the first damping hole 501、First check valve 502 and the 3rd damping hole 501 '、Consumed energy during three check valves 502 ',Decay vibration,This process is the formation of the damping characteristic of oil gas antivibrator.And the first cylinder chamber's epicoele 202 being connected with first cylinder chamber's cavity of resorption 203 is full of the high pressure nitrogen closed, second cylinder chamber's epicoele 202 ' that second cylinder chamber's cavity of resorption 203 ' is connected is full of the high pressure nitrogen closed, load is born by the elastic deformation of high pressure nitrogen, alleviating impact, this process is the formation of the elastic characteristic of oil gas antivibrator.
