Description
Technical field
The utility model belongs to the air suspension of vehicle, is specifically related to a kind of adapt air spring pressure balance cock on air suspension.
Background technology
The raising required vehicle riding comfort along with people and the development of China's passenger vehicle suspension technology, the application of air suspension on passenger vehicle is increasingly extensive.Traditional air suspension master mode adopts mechanical height valve, namely regulates the inflation/deflation to air bag by the unlatching of levelling valve valve, thus the ride-height keeping vehicle constant.Along with the popularization of system application and the development of wagon control technology, electron steering replaces traditional Mechanical course electronic control system gradually and not only increases the traveling comfort of operation and the sensitivity of reaction, and can add a lot of additional function.But in traditional mechanical type air suspension and electric-controlled type air suspension, air bellow is directly connected with mechanical type levelling valve or electromagnetic valve, when pipeline system leaks, air in air bellow can be revealed completely and cause the rigid impact of vehicle body and bump rubber, causes very large impact to the safety of passenger comfort and system.
Summary of the invention
In order to overcome the problems referred to above that prior art field exists, the purpose of this utility model is, a kind of adapt air spring pressure balance cock is provided, solve in traditional mechanical type air suspension and electric-controlled type air suspension, air when pipeline system leaks in air bellow can reveal the rigid impact causing vehicle body and bump rubber completely, causes the problem that the safety of traveling comfort and system reduces.
The adapt air spring pressure balance cock that the utility model provides, it comprises balance cock upper body, spool, seal gasket, plastic jacket, preloading spring, balance cock connector, one end of described balance cock upper body is connected by the pipeline of negative thread with mechanical type levelling valve or electromagnetic valve, the other end is connected with balance cock connector, it is inner that described plastic jacket is arranged at balance cock connector, plastic jacket inside is provided with preloading spring, described preloading spring one end is connected with the end of plastic jacket, the other end is connected with balance cock connector, it is inner that described spool is arranged at balance cock upper body, spool can be slided by plastic jacket in balance cock connector, described seal gasket is arranged between spool and plastic jacket, seal gasket one end coordinates with balance cock upper body.
Air is applied on seal gasket by the elongated hole in balance cock upper body, seal gasket is the rubber cushion of natural gum main body, be installed between spool and plastic jacket, balance cock upper body inner end surface is pressed at preloading spring effect lower seal rubber pad, play the sealing function of gas, plastic jacket is the orienting sleeve of spring, play support and guide spring effect, preloading spring is avoided to be applied directly on seal gasket, the other end of preloading spring is installed on balance cock connector, spool can slide in balance cock connector, when intake pressure is higher than air bellow internal pressure, promote spool to move to the right, air enters air bellow by the passage of the passage in spool and balance cock connector, balance cock connector is directly threaded with air bellow, also be connected with air bellow by intermediate duct.
The adapt air spring pressure balance cock that the utility model provides, its beneficial effect is, this balancing valve structure is simple, when avoiding system pipeline system leak, the air in air bellow is all drained, guarantee to retain certain pressure air in air bellow, thus the certain traveling comfort of keeping system and safety.

Mark in figure:
1. balance cock upper body; 2. spool; 3. seal gasket; 4. plastic jacket; 5. preloading spring; 6. balance cock connector.
Detailed description of the invention
With reference to the accompanying drawings, in conjunction with the embodiments, to the adapt air spring pressure balance cock that the utility model provides, be described in detail.
Embodiment
With reference to Fig. 1-Fig. 2, the adapt air spring pressure balance cock of the present embodiment, it comprises balance cock upper body 1, spool 2, seal gasket 3, plastic jacket 4, preloading spring 5, balance cock connector 6, one end of described balance cock upper body 1 is connected by the pipeline of negative thread with mechanical type levelling valve or electromagnetic valve, the other end is connected with balance cock connector 6, it is inner that described plastic jacket 4 is arranged at balance cock connector 6, plastic jacket 4 inside is provided with preloading spring 5, described preloading spring 5 one end is connected with the end of plastic jacket 4, the other end is connected with balance cock connector 6, it is inner that described spool 2 is arranged at balance cock upper body 1, spool 2 can be slided by plastic jacket 4 in balance cock connector 6, described seal gasket 3 is arranged between spool 2 and plastic jacket 4, seal gasket 3 one end coordinates with balance cock upper body 1.
Gas replenishment process: because bleed pressure is higher than air bellow internal pressure during air feed, this difference of pressure acts on the outer shroud area of seal gasket 3, when application force is higher than preloading spring 5 application force, backs down sealing rubber pad 3, flows into air bellow by spool 2.
Exhaust process: because air bellow internal pressure is higher than bar pressure during exhaust, air passes through spool 2 channeling at sealing rubber pad 3, when only having the pressure produced when the difference of pressure acting on seal gasket 3 inner ring to act on the predetermincd tension on plastic jacket 4 higher than preloading spring 5, sealing rubber pad 3 is opened, by balance cock upper body 1 passage discharged to air.
Excess pressure value in different air bellows is realized by the size of adjustment preloading spring power 5 when being vented.
