Description
Technical field
The present invention relates to the control system fields of the lift bridge for commercial car, are promoted for vehicle more particularly, to one kind
The air-path control system of bridge.
Background technology
In recent years, effect of the lift bridge in haulage vehicle was more and more widely received and was applied.When the vehicle is fully laden,
Lift bridge is fallen, and carrying is played；In the case that vehicle is unloaded or load is relatively light, lift bridge can be lifted, reduce tire
Frictional resistance between ground reduces oil consumption, while can also reduce the loss of tire.
In general, the lifting of the lift bridge of commercial car is realized by controlling the inflation/deflation of air bag.Promote operation and system
Dynamic operation is required for using compressed gas, and control system is complicated, of high cost, and when lift bridge is promoted, gas chamber is still braked,
Compressed gas is wasted, braking system performance and efficiency are reduced.
Invention content
The technical problem to be solved by the present invention is to be directed to problems of the prior art offer one kind to carry for vehicle
The air-path control system for rising bridge is normally braked the purpose is to ensure lift bridge brakeless in the state that promoted when declining carrying.
The technical scheme is that this kind includes by carrying air bag, promotion for the air-path control system of vehicle takeup bridge
The elevating control gas circuit of air bag, gas receiver, pressure regulator valve, solenoid valve and switch composition, and by brake chamber, gas receiver, pressure regulation
The control for brake gas circuit of valve, solenoid valve, relay valve and switch composition, the carrying air bag pass sequentially through solenoid valve and pressure regulator valve
It is connect with gas receiver, gas chamber is connected to the branch road that carrying air bag is connected with solenoid valve by relay valve, promotes air bag and leads to successively
It crosses solenoid valve and pressure regulator valve is connect with gas receiver.
The switch is rocker switch.
When lift bridge is promoted or is declined, the high pressure gas in gas receiver is by 3 position-5 way solenoid valve respectively to carrying
Air bag either promotes airbag aeration and carries air bag or promote gas in air bag and arranged to big by 3 position-5 way solenoid valve
Gas.
When lift bridge is loaded state, gas is reached the A mouths of relay valve, vehicle system by 3 position-5 way solenoid valve in gas receiver
When dynamic, the D mouths of relay valve have gas, and the A mouths of relay valve is made to be connected to B mouthfuls, brake chamber inflation braking.When vehicle brakeless, after
The D mouths of dynamic valve do not have gas, the A mouths of braking relay valve and B mouthfuls of disconnections, brake release.
This kind with above structure for vehicle takeup bridge air-path control system lifting and braking it is reliable, simple
Single, pneumatic control system at low cost, and ensure that lift bridge brakeless in the state that promoted, it is normally braked when declining carrying.
