Embodiment
Vehicle in the utility model embodiment is as shown in Figure 1-Figure 3: vehicle comprises car body, car body is provided with pneumatic spring, pneumatic spring, comprise air bag 1 and auxiliary tank 3, the communicating passage for air current flow is provided with between auxiliary tank 3 and air bag 1, one in described air bag and described auxiliary tank is rotatably equipped with enclosed construction, and described enclosed construction has when pneumatic spring normally works gets out of the way getting out of the way position and when being subject to inertial force, described communicating passage being carried out the close stance of closing of described communicating passage.In the present embodiment, described communicating passage is vent, and the aperture of described vent is arranged at the top of described auxiliary tank.Enclosed construction is included in double-swing shut when being subject to inertial force, and described shut is articulated with in described air bag by rotating shaft 7.Described shut comprises two round sealed plates, and the mutually arranged in a crossed manner and diameter of two round sealed plates of two round sealed plates overlaps, and the outer circumferential face of described round sealed plate coordinates with described vent seal.These two round sealed plates form X-shaped structure, and the below of described shut is hung with the weight for increasing shut inertial force.In the present embodiment, described weight is swing ball 4, described swing ball is fixed on the center position of described shut by connecting rod 6, is provided with air bag cover plate 8 in the upper end of air bag, itself and car body is connected by the base installing hole 5 that auxiliary tank 3 is arranged by pneumatic spring.
In the normal flat road surface travelled, due to the self gravitation effect of swing ball 4, swing ball connecting rod 6 is in vertical state, and X-type flabellum is in opening state at intercommunicating pore, and main gas tank cavity V1 is communicated with accessory air-space cavity V2.Now, the gas volume of inside air bag is V=V1+V2, and because gas volume is large, compressible amount is comparatively large, and the rigidity of air bag is lower, is conducive to run smoothness and travelling comfort.
When vehicle is suddenly braked, due to the effect of inertial force, swing ball 4 i.e. forward rocking motion, X-type flabellum is driven to rotate clockwise around flabellum rotating shaft 7 by connecting rod 6, intercommunicating pore can be closed by postrotational X-type flabellum, close the volume of the volume of air Jin Shengyou main gas tank cavity in rear gasbag 1, the air bag total volume so under braking state is Vb=V1.Like this, due to the remarkable reduction of gas volume, directly cause the compressible amount of front suspension air bag to reduce, the rigidity of air bag directly increases.Thus the deflection of vehicle suspension when effectively inhibit braking, the limiting stopper namely effectively reducing the amount of nodding and vehicle frame clashes into the possibility of vehicle bridge.For general damped condition, because the effect of inertial force is less, the amount of swing ball 4 forward rocking motion is less, flabellum rotating shaft 7 rotation angle is little, but the amount that the gas of intercommunicating pore can be made equally to circulate reduces, equally can the rigidity of increase air bag to a certain degree, reach the effect suppressing braking nose dive.
When vehicle suddenly accelerates, equally due to the effect of inertial force, namely swing ball 4 swings backward, X-type flabellum is driven to rotate counterclockwise around flabellum rotating shaft 7 by swing ball connecting rod 6, intercommunicating pore can be closed by postrotational X-type flabellum, close the volume of the volume of air Jin Shengyou main gas tank cavity in rear gasbag 1, the air bag total volume so under braking state is Vb=V1.Like this, due to the remarkable reduction of gas volume, directly cause the compressible amount of rear suspension air bag to reduce, the rigidity of air bag directly increases.Thus the deflection of vehicle suspension when effectively inhibit braking, the limiting stopper namely effectively reducing the amount of nodding and vehicle frame clashes into the possibility of vehicle bridge.For general accelerating mode, because the effect of inertial force is less, the amount that swing ball 4 swings backward is less, flabellum rotating shaft 7 rotation angle is little, but the amount that the gas of intercommunicating pore can be made equally to circulate reduces, equally can the rigidity of increase air bag to a certain degree, reach the effect suppressing to accelerate layback.
By the application of above-mentioned air bag on the forward and backward air suspension of vehicle, in anxious braking with when suddenly accelerating, can effectively suppress the pitching amount of vehicle adaptively.Thus effectively ensure that the travelling comfort that vehicle travels on straight road, ensure that the driving safety of car brakeing and accelerating mode and the life-span of sprung parts simultaneously.Air spring assembly structure of the present utility model is simple, cost is low, performance good, and engineer applied is worth high.
In other embodiments, swing ball in enclosed construction also can not be established, enclosed construction is arranged to the shut of three circumference uniform distributions around the shaft, when pneumatic spring normally works, these three shuts are in state of equilibrium, and ensureing that communicating passage is unimpeded, an energy when being subject to inertial force in three shuts is by vent seal.
In other embodiments, enclosed construction also can comprise a connecting rod, the lower end of connecting rod is provided with as two shuts in X-type in the present embodiment, rod hinge connection is in air bag and be positioned at above vent, when pneumatic spring is subject to inertial force, connecting rod can swing and drive shut to swing simultaneously, and communicating passage is closed by shut, thus increases the rigidity of pneumatic spring.
The utility model also provides a kind of embodiment of pneumatic spring: as shown in Figure 1-Figure 3, in the above-described embodiments, has made with regard to the structure of the pneumatic spring in vehicle and having illustrated, no longer described in detail in the present embodiment.
