Description
Technical field
The utility model relates to a kind of air suspension three axle passenger vehicle lift bridge control system.
Background technology
Existing a kind of Vehicular air suspension electric-controlled lift system, is by dynamo-electric combination, carries out Vehicular air suspension electric-controlled lift system mechanical and that electronic switch is controlled according to demand.By two pipelines, source of the gas is communicated with air bag spring; Article 1, come round from change-over valve and air bag spring by mechanical levelling valve, hand, Article 2 by highly controlling driving valve, hand communicates with air bag spring from change-over valve.Provide power supply by automatic and hand-operated chargeover switch for electromagnetic valve coil; Make hand be transformed into and highly control driving valve from the air bellow control of change-over valve by direction switch.In this scheme, circuit control needs two switches and corresponding electromagnetic valve, and outside mechanical levelling valve, also needs special height control driving valve, whole control realize more complicated, increasing of the complexity of system, especially electric elements, easily causes the reliability decrease of system.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of three axle passenger vehicle lift bridge control system that realize lift bridge lifting according to vehicle condition.
The utility model overcomes the technical scheme that its technical matters adopts:
These three axle passenger vehicle lift bridge control system, comprise the left front air bag and the right front air bag that are arranged on respectively two ends, vehicle propons left and right, be arranged on left air bag and the right air bag at two ends, lift bridge left and right, the jackshaft that is arranged on lift bridge middle part promotes air bag, and be arranged on respectively the left back air bag I at two ends, back axle left and right, left back air bag II and right back air bag I, right back air bag II, described left front air bag and right front air bag are connected in one end of threeway I through levelling valve I, the another two ends of described threeway I are connected to threeway II and threeway V, jackshaft lifting air bag is connected in the another two ends of threeway II through by pass valve through normally closed solenoid valve and air receiver, the frequent three-way electromagnetic valve I of described left air bag and left back air bag I are connected in threeway III, the frequent three-way electromagnetic valve II of described right air bag and right back air bag I are connected in threeway IV, one end of described left back air bag II and threeway III is connected in threeway V through levelling valve II, one end of described right back air bag II and threeway IV is connected in threeway V through levelling valve III, described normally closed solenoid valve, three-way electromagnetic valve I and normal open electromagnetic valve II are electrically connected on switch.
The beneficial effects of the utility model are: by switch control normally closed solenoid valve, three-way electromagnetic valve I and normal open electromagnetic valve II, in the time that vehicle is subject to heavy lift, jackshaft promotes air bag air pressure and discharges, after left air bag and the ventilation of right air bag, lift bridge wheel is contacted with ground, lift bridge bears carload.When Vehicle Driving Cycle is in good road surface, when car load is lighter, jackshaft promotes airbag aeration, and the air pressure in left air bag and right air bag discharges by normal open electromagnetic valve I and normal open electromagnetic valve II, and now lift bridge wheel is liftoff, effectively reduces vehicle friction force.Control system is simple in structure, and lift bridge lifting can not cause interference to the normal work of the suspension air bag of front-rear axle, has improved the reliability of vehicle.

Detailed description of the invention
Below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the utility model is described further.
These three axle passenger vehicle lift bridge control system, comprise the left front air bag 1 and the right front air bag 5 that are arranged on respectively two ends, vehicle propons left and right, be arranged on left air bag 8 and the right air bag 9 at two ends, lift bridge left and right, the jackshaft that is arranged on lift bridge middle part promotes air bag 2, and be arranged on respectively the left back air bag I 3 at two ends, back axle left and right, left back air bag II 4 and right back air bag I 6, right back air bag II 7, left front air bag 1 and right front air bag 5 are connected in one end of threeway I 10 through levelling valve I, the another two ends of threeway I 10 are connected to threeway II 11 and threeway V 14, jackshaft lifting air bag 2 is connected in the another two ends of threeway II 11 through by pass valve through normally closed solenoid valve and air receiver, the frequent three-way electromagnetic valve I of left air bag 8 and left back air bag I 3 are connected in threeway III 12, the frequent three-way electromagnetic valve II of right air bag 9 and right back air bag I 6 are connected in threeway IV 13, one end of left back air bag II 4 and threeway III 12 is connected in threeway V 14 through levelling valve II, one end of right back air bag II 7 and threeway IV 13 is connected in threeway V 14 through levelling valve III.When car load is heavier or when car test, Push switch makes electromagnetic valve power-off, when normally closed solenoid valve power-off, normally closed solenoid valve loop is closed, jackshaft promotes air bag 2 air pressure and discharges, normal open electromagnetic valve I and normal open electromagnetic valve II circuit communication, left air bag 8 on lift bridge and right air bag 9 are communicated with air receiver by pipeline with the left back air bag I 3 on back axle, left back air bag II 4, right back air bag I 6 and right back air bag II 7, thereby lift bridge wheel contacts with ground, and lift bridge bears carload.
When Vehicle Driving Cycle is in good road surface, car load is lighter, in normal driving process, and Push switch, when electromagnetic valve energising, normally closed solenoid valve circuit communication, the jackshaft on lift bridge promotes air bag 2 and inflates.And normal open electromagnetic valve I and normal open electromagnetic valve II loop are closed, because the left back air bag I 3 on back axle, left back air bag II 4, right back air bag I 6 and right back air bag II 7 are independent with left air bag 8 and right air bag 9 pipelines on lift bridge, air pressure in left air bag 8 and right air bag 9 discharges by normal open electromagnetic valve I and normal open electromagnetic valve II, now lift bridge wheel is liftoff, effectively reduces vehicle friction force.
Because normally closed solenoid valve, three-way electromagnetic valve I and normal open electromagnetic valve II are subject to same switch control, the synchronism of the each air bag work of simple and effective guarantee, Switching Power Supply connects normal electricity, can not be subject to the impact of ignition lock and other consumers, under parking, driving cycle, all can realize the lifting of lift bridge.
Left front air bag 1 and right front air bag 5 are subject to the control of levelling valve I, left back air bag I 3 and left back air bag II 4 are subject to the control of levelling valve II, right back air bag I 6 and right back air bag II 7 are subject to the control of levelling valve III, the height that can ensure homonymy air bag is consistent, inflation/deflation is kept strokes, avoid the problems such as the carrying of homonymy air bag is inconsistent, and vehicle body is unstable.Ensureing, under the prerequisite of the normal work of suspension air bag, to have realized lifting, the decline of lift bridge, both ensureing that air suspension provided reliably, stablizes, comfortable driving performance, realizing again the light conversion that economy run and power carry.
