In view of generalization, the pilot valve 3, the first main valve 4, and the second main valve 5 have substantially the same configuration in the present embodiment, in which the first main valve 4 and the second main valve 5 are completely identical, and only the relief port 326 is provided in many different places of the pilot valve 3. In the embodiment, only the valve device part is described, and as for conventional parts of the whole vehicle such as an air compressor, a suspension, an air bag, an air tank and the like, the valve device needs to be used due to mature technology, but the parts are not changed, so that the valve device is not described, and the attached drawings are not shown. In the embodiment, the pneumatic suspension of the rear axle of the automobile is taken as an example, wherein two height sensors 2 are provided, which respectively feed back height signals of the left wheel and the right wheel, and the fed back signals are respectively used for controlling the first main valve 4 and the second main valve 5 of the left wheel and the right wheel corresponding to the inflation/deflation of the suspension air bags. In the concrete implementation, for the pneumatic suspension of the front axle of the automobile, according to the principle that three points determine one plane, the front axle only uses one height sensor 2 for controlling the heights of a left vehicle and a right vehicle, so that a parallel valve is required to be added to a left inflation air path and a right inflation air path. In addition, for the whole pneumatic suspension, only one pilot valve 3 is needed as a main valve switch, and the front axle and the rear axle do not need to be provided with the pilot valve 3 at the same time.
The pilot valve 3 as a master switch, an air compressor and an air tank connected to a main port 325, supply compressed air and pressure Pi to the port 325, and receive intake pressure Pi from a core 322a (area S2) of the main spool 322 toward the port 325. The second valve cavity on the pilot valve 3 is connected with the second valve cavity of the first main valve 4 and the second valve cavity of the second main valve 5, and provides the air pressure Pa throttled by the valve core air tap 322d for them according to the requirement. The area of the pushing end 322b is S1, and the first valve cavity in which the pushing end 322b is located is specifically communicated with the control valve cavity 311 through an air passage and bears the air pressure transmitted from the control valve cavity 311.
The height sensor 2 feeds back the vehicle suspension height information to the controller 1 when the vehicle is running or in other required states, the controller 1 outputs electric signals to control one or more of the control valve of the pilot valve 3, the control valve of the first main valve 4 and the control valve of the second main valve 5 according to program judgment, so that the control valve generates a certain opening degree, after the compressed air of the bypass air path 7 is throttled, by injecting the first cavity 321a of the pilot valve 3 or the first cavity 321a of the first main valve 4 or the first cavity 321a of the second main valve 5, and generates a certain pressure P0 (corresponding to the pilot valve 3) or P1 (corresponding to the first main valve 4) or P2 (corresponding to the second main valve 5), the pressure is less than or equal to the pressure Pi of the inlet 325, and generates a certain pressure to the pushing end 322b, which is (P0 × S1), (P1 × S1), and (P2 × S1), respectively.
Main spool 322 bears thereon: the pressure on the push end 322b side, the pressure on the core 322a side, and the main valve spring 322 c. The elasticity is as follows: f = F0+ k × l, where F0 is the initial force of the spring, k is the spring rate, and l is the amount of compression of the spring in the pressure chamber. Since the compressed air at the pushing end 322b is throttled and the end area of the pushing end 322b is much larger than that of the core 322a, the pressure at the pushing end 322b (P0S 1) can be adjusted within the following range: 0 to (Pi S1).
When the suspension airbag needs to be inflated, the controller 1 outputs a signal, the electromagnet 314 of the control valve body 31 generates a magnetic field, a certain suction force is generated on the control valve core 313, the control valve core 313 overcomes the resistance of the control valve spring 315 and the gravity thereof to move upwards, the control valve nozzle 312 is opened by a certain opening degree, so that air in the bypass air passage 7 enters the interior after being throttled, a certain throttling and pressure P0 after being throttled are formed, when the pressure (P0S 1) at the pushing end 322b of the main valve core 322 is greater than F0+ Pi S2, the main valve core 322 moves towards the side of the air port 325, so that the valve core nozzle 322d is communicated with the air inlet 325 and the inflation inlet, and when the first main valve 4 or the second main valve 5 is also communicated with the air port 325 and the communication pipe 6, the airbag of the automobile suspension is inflated. The intensity and duration of the output signal of the controller 1 determine the amplitude and time of the control valve.
The invention also provides an automobile which comprises the automobile suspension inflation and deflation valve device with instant response.
The control valve body is designed into a structural form with opening degree regulation (throttling), the controller regulates the opening degree of the control valve body by converting signals of the height sensor into control parameters of the control valve body, so that the air pressure acting on the main valve element is regulated, the air pressure and the spring force of the main valve element jointly act to push the main valve element to move, new balance is achieved, and inflation or deflation is realized. Through the height sensor signal of developments, can dynamic control inflate or deflate to reach the transient state demand that pneumatic suspension offset/deflated, realize the immediate response, keep the stability and smooth-going of suspension height, improve the travelling comfort that the car went.
