Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Detailed description provided below and specific embodiment indicate the preferred embodiments of the present invention, but their objects only for explaining, but not limit the scope of the invention.
In FIG, gas spring 1 has been hermetic, and when vehicle load changes, the volume of gas spring 1 is inevitable to be changed, according to the ideal-gas equation under temperature constant state thereupon
p×V
n=const
The air pressure inside of gas spring 1 also can change.When vehicle load increases, the volume of gas spring 1 reduces, and air pressure raises, and when vehicle load reduces, gas spring 1 volume increases, and air pressure reduces.
Pneumatic variable current device 2 is made up of pneumatic variable displacement device 3 and slide rheostat 4, the resistance of slide rheostat 4 is changed by pneumatic variable displacement device 3, therefore, when switch 6 is closed and vehicle power 5 has electric, pneumatic variable current device 2 just can change the field current of electromagnetic damper 7 according to the gas pressure in gas spring 1, thus affects the damping characteristic of electromagnetic damper 7.
In fig. 2, by tracheae 9, the gas in gas spring 1 is incorporated in pneumatic variable displacement device 3, tracheae 9 is linked together by nut 14 and the end cap 15 in pneumatic variable displacement device 3, end cap 15 is threaded with shell 18, by T-shaped bar 19, pneumatic variable displacement device 3 is divided into A chamber and B chamber, the large end of T-shaped bar is equipped with seal ring 16, ensures the tightness between A chamber and B chamber, and the other end of T-shaped bar 19 is fixed together by the slide plate 20 of nut 21 with slide rheostat 4.When the gas pressure acted on T-shaped bar 19 in A chamber is greater than the elastic force of spring 17, T-shaped bar 19 just drives the slide plate 20 of slide rheostat 7 to move right, and according to the connection of wire in Fig. 2, the resistance of slide rheostat 4 will reduce; When the gas pressure acted on T-shaped bar 19 in A chamber is less than the elastic force of spring 17, T-shaped bar 19 just drives the slide plate 20 of slide rheostat 7 to be moved to the left, and the resistance of slide rheostat 4 will increase.
