Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1, the present invention, which provides a kind of rail vehicle braking, alleviates fault handling method, including blast main 1, total
Braking excision cock 2, brake control 3 and checking cylinder 4 are in series on air hose 1.
Wherein, brake control 3 includes filling wind-powered electricity generation magnet valve 5, air draft solenoid valve 6, relay valve 7.Connected successively by pipeline
Air pipe line is filled in the common chamber for filling wind-powered electricity generation magnet valve 5 and relay valve 7 formation being connected between blast main 1 and checking cylinder 4.By pipeline according to
The common chamber and air draft solenoid valve 6 of the secondary relay valve 7 being connected between checking cylinder 4 and blast main 1 form exhaust pipeline, air draft electricity
6 one end of magnet valve connection exhaust duct (not indicated in figure), the other end of exhaust duct lead directly to air.Brake control 3 further includes tightly
Anxious brake piping, emergency brake pipe include by pipeline be connected in turn bare weight valve 10 between blast main 1 and checking cylinder 4,
The urgent chamber of emergency braking solenoid valve 11 and relay valve 7, bare weight valve 10 are connect by pipeline with air spring 9.In control for brake
The arrival end of device 3 is provided with filter 12.In the pipe that relay valve 7 is often connect with chamber with filling wind-powered electricity generation magnet valve 5 and air draft solenoid valve 6
Road is provided with the first pressure sensor 13 for signal piping wind pressure, is connected between air spring 9 and bare weight valve 10
The second pressure sensor 14 for signal piping air pressure is serially connected on pipeline.
As shown in Figure 1, in service braking, filling wind-powered electricity generation magnet valve 5 electric must fill air pipe line connection, and total wind pressure is via vehicle system
Dynamic excision cock 2, filter 12, relay valve 7 enter checking cylinder 4, realize braking.
In emergency braking, emergency braking solenoid valve 11 obtains electric emergency brake pipe and connects, and total wind pressure is via vehicle system
Dynamic excision cock 2, filter 12, relay valve 7 enter checking cylinder 4, realize braking.
For relay valve 7, in service braking, pre-control AC2 pressure is controlled by filling wind-powered electricity generation magnet valve 5 and air draft solenoid valve 6
System, AC2 pre-controls air chamber pressure are detected by first pressure sensor 13, and have electronic brake control unit to carry out closed loop control
System.When AC2 pre-controls air chamber pressure is more than control deviation less than AC goal pressures, fills the energization of wind-powered electricity generation magnet valve 5 and open AC2 pre-control gas
Wind access is filled in room, increases AC2 air chamber pressures；When AC2 pre-controls air chamber pressure is more than control deviation higher than AC goal pressures,
The air draft access of the pre- air control chambers of AC2 is opened in the power-off of air draft solenoid valve 6, reduces AC2 air chamber pressures；When AC2 pre-control air chamber pressures
During with AC goal pressures relatively, that fills the power-off closing pre- air control chambers of AC2 of wind-powered electricity generation magnet valve 5 fills wind access, and air draft solenoid valve 6 is logical
The air draft access of the electrically disconnected pre- air control chambers of AC2 enables the pre- air control chambers of AC2 basicly stable constant.
BCU is disconnected after the pre- governor pressures of AC2 enter packing state and inputs total wind wind regime, since goal pressure is unchanged, fills wind
Solenoid valve 5 and air draft solenoid valve 6 are all off state, and therefore, the pressure of the pre- air control chambers of AC2 can be basically unchanged, relay valve
Original packing state can be kept, brake-cylinder pressure is made also to keep original pressure constant.When AC2 is packing state, respectively
Although the practical AC2 pressure of vehicle and the bias of goal pressure, all in AC pressure control deviations, the size of deviation may be endless
It is exactly the same.For the vehicle that AC pressure divergences limit under stress, the leakage of the very little of AC2 pressure, which will result in, fills wind-powered electricity generation magnet valve 5 and mends
Air control system, but since the total wind in upstream has emptied, filling the benefit air control system of wind-powered electricity generation magnet valve 5 not only rises AC2 pressure, makes instead
AC2 pressure reductions, the reduction of AC2 pressure, which further makes to fill wind-powered electricity generation magnet valve 5, opens, and the pre- governor pressures of AC2 is caused to be emptied completely.For
AC pressure divergences the pressure divergence upper limit vehicle, if AC2 leakages also very little, then AC pressure is maintained at pressure divergence lower limit
Above time possibility will be very long, during this period of time, does not have and fills wind and air draft control, AC2 pressure can be longer
It keeps being basically unchanged or slowly declining in time.
In emergency braking, if urgent pre- governor pressure AC1 pressure decrease slows, brake-cylinder pressure BC drop to often
Then no longer decline during the pressure value to be matched with pre- governor pressure AC2, will occur at this time brake-cylinder pressure have it is certain become smaller but
It will not alleviate.If urgent pre- governor pressure AC1 pressure declines quickly, brake-cylinder pressure BC follows decline very fast, on relay valve
Hooking shellfish body valve port cannot close in time, then brake-cylinder pressure BC would fall to less than the pressure to match with commonly using pre- governor pressure AC2
Force value, then above hooking shellfish will push total air valve seat to open valve port, prepare to supplement difference from total wind pressure, but total wind pressure at this time
Power is already below BC pressure, therefore valve port will be always on, and brake pressure BC also drops to zero, will occur checking cylinder alleviation at this time.
Due to the above-mentioned characteristic of relay valve 7, braking occurs in certain section compartment of train and does not alleviate, driver operation guest room seat
After lower vehicle braking excision cock carries out pressure alleviation, during the situation that time slack does not delay when occurring once in a while, pass through following processing method
Emergent management is carried out, alleviates braking to rapidly artificial, subsequent rescue is checked or wait in order to which train goes back to library
Specifically comprise the following steps：
Step 1 when vehicle is in relieved state, if certain vehicle braking occurs and do not alleviate, operates vehicle braking at this time
After cutting off cock 2, if braking is still not alleviated, forces to connect the air pipe line that fills in blast main 1 and brake control 3, lead to
Alleviation can be realized in overcharging pipeline air draft.
Specially：
1st, level is braked in operation controller handle to " braking " position, " braking " position for the maximum of controller.
At this point, filling wind-powered electricity generation magnet valve 5 obtains electric-opening, blast main 1 is connected with the common chamber of relay valve 7, service braking chamber is pre-
Governor pressure AC2 by it is common fill wind-powered electricity generation magnet valve 5, vehicle braking excision cock 2 empties, checking cylinder BC pressure passes through in relay valve 7
Exhaust outlet empty therewith, release of brake.
2nd, after alleviation, controller handle is pushed into again " to alleviate " position.
Step 2, when vehicle is in braking application state, after operating certain vehicle braking excision cock 2 at this time, if there is
Braking is not alleviated, then forces to connect the exhaust pipeline in brake control 3, can be realized by exhaust pipeline air draft slow
Solution.
Specially：
1st, controller handle is operated to " alleviation " position.
At this point, 6 dead electricity of air draft solenoid valve is opened, by the common chamber of relay valve 7 by exhaust duct and atmosphere,
The pre- governor pressure AC2 of service braking chamber is emptied by common air draft solenoid valve 6, and checking cylinder BC pressure passes through relay valve 7
Interior exhaust outlet empties therewith, release of brake.
2nd, after alleviation, controller handle is pushed into again to brake initial level.
