Embodiment
One embodiment of automobile is as shown in Fig. 1 ~ Fig. 3, including vehicle bridge（Not shown in figure）The suspension being connected with vehicle bridge
Structure, suspension frame structure includes air spring 10, guide rod 11 and air damping system, and air damping system includes being fixed on chassis
Source of the gas 1 on crossbeam 7, the magnetic valve 2 being connected by pipeline 6 with source of the gas 1, the air damping being connected by pipeline 6 with magnetic valve 2
Device 3.
Wherein, air bump 3 has working cylinder 32, upper connecting portion 31, lower connecting portion 33, and upper connecting portion 31 is by upper
Mounting bracket 9 and vehicle frame（Not shown in figure）It is connected, lower connecting portion 33 is connected by lower mounting bracket 8 with vehicle bridge.Working cylinder
Charge and discharge valve is provided with 32, the pressure for detecting the internal gas pressure of working cylinder 32 in real time is provided with the charge and discharge valve
Sensor 4, pressure sensor 4 is arranged in charge and discharge valve, so there is no need to do any change to working cylinder 32 in addition,
Set convenient.The signal of pressure sensor 4 is connected with the display that pressure value is measured for showing（Not shown in figure）, the display
On guidance panel 5, guidance panel 5 is located in driver's cabin, is easy to driver observation pressure value.
Magnetic valve 2 is arranged in the upstream of air bump 3, has atmosphere connection port and concatenation on magnetic valve 2
Air inlet and gas outlet in pipeline 6, air damping system also include being used to control magnetic valve 2 in the work of air bump 3
Make to turn on air inlet and gas outlet when gas pressure in cylinder body 32 is relatively low, gas outlet and air company are turned on when gas pressure is higher
Port, disconnection air inlet and gas outlet and the hand control switch for disconnecting gas outlet and atmosphere connection port when gas pressure is suitable
（Not shown in figure）, hand control switch is a kind of three kinds of works of the switch, respectively corresponding above-mentioned magnetic valve 2 with three gears
Make state, the hand control switch is also disposed on guidance panel 5, be easy to driver to observe pressure value, while being adjusted.
Air bump 3 have four and two-by-two positioned at vehicle bridge propons and back axle on, magnetic valve 2 have two and respectively with it is preceding
Bridge is connected with the air bump 3 on back axle, for controlling two air bumps 3 on propons or back axle simultaneously, therefore
Hand control switch has two and is respectively used to control the working condition of two magnetic valves 2.
The operation principle of air damping system is：Due to being provided with pressure sensor 4 on working cylinder 32, therefore driver is logical
The gas pressure in working cylinder 32 can just be grasped in real time by crossing the display on guidance panel 5, so as to air bump
Damping force has one most to get information about.When vehicle is in high-speed working condition downward driving, in order to ensure the even running of vehicle, make car
Relatively good control stability is kept, the excessive damping force of air bump 3 is not needed now, therefore can be by controlling manually
The regulation of system switch makes magnetic valve 2 turn on gas outlet and atmosphere connection port, and at this moment working cylinder 32 will deflate, working cylinder 32
Interior gas pressure will be reduced, and its pressure value can be shown on guidance panel 5 in real time, when pressure be reduced to it is certain suitable
During value, switch the gear of hand control switch, magnetic valve 2 is disconnected gas outlet and atmosphere connection port, so that working cylinder 32
It is interior to keep certain pressure value, it is ensured that certain damping force.
When vehicle is travelled on uneven road surface, in order to ensure the even running of vehicle, make passenger's acquisition is relatively good must multiply
Comfortableness is sat, it is necessary to air bump 3 has than larger damping force, magnetic valve 2 is at this moment made by the regulation of hand control switch
Air inlet and gas outlet are turned on, at this moment working cylinder 32 will be inflated, and the gas pressure in working cylinder 32 will be raised, pressure
Value can be shown on guidance panel 5 in real time, when pressure rise is to certain desired value, switch the gear of hand control switch,
Magnetic valve 2 is set to disconnect air inlet and gas outlet, so that keeping certain pressure value in working cylinder 32, it is ensured that certain damping
Power.
In the other embodiment of automobile：Display and hand control switch can not also on same guidance panel, and
It is to be provided separately；Pressure sensor can also be arranged on other positions of working cylinder；Magnetic valve can also have four, accordingly
Hand control switch also has four, or a magnetic valve only one of which, hand control switch also only one of which.
The implementation of air damping system is for example shown in Fig. 1 ~ Fig. 3, and the concrete structure of air damping system is real with above-mentioned automobile
The air damping system applied described in example is identical, will not be described in detail herein.
