Embodiment
As depicted in figs. 1 and 2, a kind of air damping device for mobile accumulation power supply car, this device comprises liquid flow energy storage battery and four above air bumps, air bump is arranged on the bottom of the liquid flow energy storage battery of mobile power vehicle; This device is four air bumps preferably, are arranged on respectively the bottom, four turnings of the liquid flow energy storage battery of mobile power vehicle; Supply vehicle is in mobile transportation, and air bump can guarantee that liquid flow energy storage battery is steady, safety, and four air bumps make liquid flow energy storage battery stressed evenly, and supply vehicle is more steady in mobile transportation.
As shown in Figure 3, air bump comprises that inside is equipped with compressed-air actuated air spring and the variable vibration absorber of damping, and one end of vibration absorber is positioned at the inside of air spring, and the two fixing compact connects.Air spring has relatively constant low frequency of natural vibration, can improve the stationarity that supply vehicle travels, and the deformation characteristic of air spring is better than Rubber shock-absorbing pad, can be learnt by the contrast force-stroke curve of Fig. 4, Fig. 5 and Fig. 6; Concussion when vibration absorber is mainly used to suppress rebound after spring shock-absorbing and from the impact on road surface, is used the variable vibration absorber of damping to make natural frequency low, vibration absorber long working life.
Air spring main parts size has upper cover 1, clasp 2, piston 3 and backstop 4, also comprises capsule 6 and height adjusting valve 5; Upper cover 1, piston 3 and capsule 6 composition sealing capsules, sealing capsule is filled with compressed air and forms air bag; Piston 3 is one end that a part for vibration absorber is positioned at vibration absorber, air bag is connected with upper cover 1 by clasp 2, and piston 3 is positioned at inside air bag, and backstop 4 is arranged on one end that piston 3 is connected with air bag, backstop 4 can cushion the moment impact load on road surface, avoids vehicle to occur severe jolt.Air spring also comprises auxiliary air reservoir 7, between air spring and auxiliary air reservoir 7, is provided with throttle orifice 8, and throttle orifice 8 can play damping action.Air spring is the rubber bag tank that cord strengthens, rubber bag tank endurance, heat-resisting, good stability of the dimension that cord strengthens.
Levelling valve 5 can make the working depth of air spring under any load, keep necessarily, also can making spring under same load, have different height, therefore, can further guarantee the stationarity of supply vehicle in transportation.Air spring is the rubber bag tank that a kind of cord strengthens, and rubber bag tank endurance, heat-resisting, good stability of the dimension that cord strengthens are filled with Compressed Gas (air pressure is 0.2～0.7MPa) in the air spring of sealing, utilize the compressibility of gas to play spring action; By the connection principle of gas in air spring, can realize easily many bridges axle load and braking equilibrium of forces, protection increases the service life of axle; Between air spring body and auxiliary air reservoir, be provided with a throttle orifice, can play damping action, supply vehicle balance on more severe road surface is travelled.
Air bag utilizes height adjusting valve 5 can control capsule internal gas pressure to make the rigidity of air spring have adjustability, and in the time acting on load on spring and increase, air pressure raises, the rigidity of spring increases, otherwise, in the time that load reduces, air pressure in spring declines, and rigidity reduces.The rigidity of air spring becomes with load, thereby the natural frequency of vibration is constant under any load, makes spring assembly have almost constant performance, extends the life-span of vibration absorber.
The coefficient of elasticity of air spring also can regulate as required automatically, and the coefficient of elasticity of spring is to regulate by the flow of air in air bag bellows.On shortwave road surface or cross at a high speed when curved, the portion gas in bellows can locked, and in the time of bellows pressurized, air mass flow reduces, and makes spring hardening, and to reduce, vehicle body rises and falls and raising vehicle body stability.On prevailing roadway, all air can flow freely, and when bellows pressurized, air mass flow strengthens, thereby soft spring and maximum driving comfort is provided.When long-time low speed driving, spring can deliquescing improve damping comfortableness and fail safe.
Air damping also incorporates traditional chassis lifting technology wherein.While running at high speed, bodywork height reduces automatically, guarantees that good High-speed running stability reduces windage and oil consumption simultaneously thereby improve grounding performance.When jolting road surface, chassis raises automatically, passes through performance to improve at a slow speed.In addition, air damping system can also keep vehicle body level height automatically, and no matter unloaded fully loaded, bodywork height can be invariable, and under any load condition, the spring travel of shock mitigation system all keeps necessarily like this, thereby shock absorbing characteristics can not be affected substantially.Even if therefore, under full load conditions, vehicle body is also easy to control.
