Accompanying drawing explanation
Fig. 1 is the structural representation of this bus body form regulation system of the embodiment of the present invention;
Wherein: 1-angular transducer, 2-control unit, 3-air receiver, the left air bag electromagnetic valve of 4-, the right air bag electromagnetic valve of 5-, suspension bags on the left of 6-, suspension bags on the right side of 7-, 8-check valve, 9-ECAS control system.
Detailed description of the invention
Fig. 1 shows a specific embodiment of this bus body form regulation system of the present invention, and this system mainly comprises left side suspension bags 6, right side suspension bags 7, angular transducer 1, air receiver 3, left air bag breather pipe, right air bag breather pipe, left air bag electromagnetic valve 4, right air bag electromagnetic valve 5 and control unit 2.Wherein, left side suspension bags 6 is arranged in the left side of passenger vehicle suspension, and right side suspension bags 7 is arranged in the right side of passenger vehicle suspension.Air receiver 3 is the special air receiver of gas spring, and it is for providing source of the gas.Left air bag breather pipe is connected between described air receiver 3 and left side suspension bags 6, to be communicated with air receiver 3 gas phase by left side suspension bags 6.Right air bag breather pipe is connected between described air receiver 3 and right side suspension bags 7, to be communicated with air receiver 3 gas phase by right side suspension bags 7.Left air bag electromagnetic valve 4 is arranged on left air bag breather pipe, to control the break-make of left air bag breather pipe.Right air bag electromagnetic valve 5 is arranged on right air bag breather pipe, to control the break-make of right air bag breather pipe.Control unit 2 is control circuit plate structure, also can be the controller architecture of outsourcing, it was both electrically connected with described angular transducer 1, be electrically connected with left air bag electromagnetic valve 4 again, also be electrically connected with right air bag electromagnetic valve 5, during work, the passenger vehicle angle of inclination size that this control unit 2 can sense according to described angular transducer 1 controls the on off state of described left air bag electromagnetic valve 4 and right air bag electromagnetic valve 5.
In this example, described passenger vehicle suspension is made up of front suspension and rear suspension, and described left side suspension bags 6 has three, and one of them is arranged in the left side of described front suspension, and two other is arranged in the left side of described rear suspension.Described right side suspension bags 7 has three, and one of them is arranged in the left side of described front suspension, and two other is arranged in the left side of described rear suspension.
In order to prevent the gas backflow in the suspension bags 6 of left side, this example is provided with the check valve 8 that described left side suspension bags 6 is pointed in its ventilation direction on described left air bag breather pipe.In like manner, this example is also provided with the check valve 8 that described right side suspension bags 6 is pointed in its ventilation direction on described right air bag breather pipe.
The control method of this routine this bus body form regulation system is specific as follows:
When angular transducer 1 senses that passenger vehicle is tilted to the left, and left-leaning angle exceedes preset value, and (this value can think setting, generally be not more than 28 °) time, angular transducer 1 exports corresponding electric signal to control unit 2, control unit 2 controls left air bag electromagnetic valve 4 and opens after receiving this electric signal, thus the gas making air receiver 3 provide (this gas is generally pressurized air) enters left side suspension bags 6 by left air bag electromagnetic valve 4, suspension bags 6 obtains gas and becomes large rising immediately, the left-leaning angle of passenger vehicle is reduced and reaches safety value (this value also can artificially set, generally be not more than 28 °) after, left air bag electromagnetic valve 4 is closed, suspension bags 6 is to the left stopped to inflate.
When angular transducer 1 senses that passenger vehicle is tilted to the right, and Right deviation angle is when exceeding preset value, angular transducer 1 exports corresponding electric signal to control unit 2, control unit 2 controls right air bag electromagnetic valve 5 and opens after receiving this electric signal, thus the gas making air receiver 3 provide enters right side suspension bags 7 by right air bag electromagnetic valve 5, suspension bags 7 obtains gas and becomes large rising immediately, passenger vehicle Right deviation angle is reduced and after reaching safety value, right air bag electromagnetic valve 5 is closed, and stops suspension bags 7 to the right to inflate.
With reference to shown in Fig. 1, if Passenger Vehicle is configured with ECAS control system 9 simultaneously, when side tilt angle exceedes preset value, this routine this bus body form regulation system can disconnect the power supply of ECAS control system automatically, and work alone, avoid the intervention of ECAS control system and affect the adjustment of air bag height.
Certainly, above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to people can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the Spirit Essence of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
