When electric control circuit failure, the output pressure of each bridge modular pressure is then controlled by its pneumatic control circuit.Its control process
As follows, driver depresses brake pedal, electronic control main valve exported according to pedal travel three road relevant pressures air (it is therein all the way in
Way is divided into two-way).The control mouth of five mouthfuls of relay valves is accessed all the way, which is used to control the brake pressure of first three axis.
Another two-way accesses trailer valve, and tow channel gas is exported after trailer valve converts and is pressed onto another five mouthfuls of relay valves, wherein being all the way control
Pressure, another way are gas source.The brake pressure of three axis after this five mouthfuls of relay valves are used to control.It is come out from five mouthfuls of servo valve outlets
Pressure air enters the control mouth of bridge modular pressure, so that control bridge modular pressure is output to the air pressure of brake chamber, reaches
To the purpose of control brake force.But at this time the brake force of each axis be it is the same, cannot be carried out corresponding according to the difference of axis weight
Adjustment.
As shown in figure 3, intelligence rail electric car parks spring brake chamber (spring air chamber in Fig. 3), energy in 2 axis and the setting of 5 axis
Enough park safety of the vehicle when level road, climb and fall are realized without driver.Parking brake function is mainly by parking brake/slow
Solution button (parking button in Fig. 3) parks memory valve, parks relay valve and parking brake gas chamber composition.When normal driving,
It is filled with compressed air in band parking brake gas chamber, spring is compressed, and braking is alleviated.In the case where car speed is zero, when
When driver presses parking brake button (parking button) sending parking brake instruction, memory valve events are parked, relay valve control is parked
The air of donsole is discharged, and parks servo valve events, and the compressed air with parking brake gas chamber arranges Xiang great Qi by parking relay valve,
Spring stretches out, and implements braking.When alleviation, driver presses alleviation button, parks memory valve events, and the control mouth for parking relay valve is filled
Enter compressed air, park servo valve events, the compressed air in gas source enters parking brake gas chamber by parking relay valve, compresses
Spring, parking brake are alleviated.
As shown in figure 4, emergency braking actively triggers after weighing road conditions and urgency level by driver.Operation interface is promptly to press
Button input pattern obtains electric application.By right of way mode, corresponding maximum deceleration should be reached, cannot be released before parking.Emergency braking
Highest priority, once investment, is not influenced by any equipment.Emergency braking function is mainly by danger button, urgent solenoid valve, limit
The components such as pressure valve composition.When driver presses danger button, urgent solenoid valve must be conducted, and compressed air is arrived through pressure limiting valve pressure limiting
Enter brake chamber (gas chamber) after abs valve after the pressure of setting, emergency braking applies.
