Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
A kind of configuration drawn and braked and control system, as illustrated in fig. 1 and 2, in units of a car, each car includes
A set of traction control unit 2, two sets of brak control units 5, passes through train between traction control unit 2 and brak control unit 5
Network 1 realizes information exchange；Four traction inversion modules 3 are connected with traction control unit 2, draws and is connected on inversion module 3
Permanent magnet direct driving motor 4；Often cover on brak control unit 5 and be correspondingly connected with two anti-sliding control valves 6, anti-sliding control valve 6 and permanent magnetism
Direct driving motor 4, which is installed on, to be same as in rotating shaft 7.
Traction control unit 2 transmits electric braking force value signal to brak control unit 5, and brak control unit 5 is connected to braking
Instruction, braking level, the weight of train of brak control unit 5 itself calculating and the electricity system received from traction control unit 2
Power value signal, the air damping power of train needs is finally calculated, is then allocated according to the distribution principle of setting themselves.
In Fig. 2, in units of a bogie, vehicle air feed is connected with two anti-sliding control valves 6.Brak control unit 5
On be connected with a link valve 51, link valve 51 is connected with two anti-sliding control valves 6 being connected in same control unit.It is anti-
Pressure sensor 9 is connected with sliding control valve 6, checking cylinder 10 is connected with pressure sensor 9.Anti-sliding control valve 6 includes anti-
Sliding charge valve 61 and anti-skidding exhaust valve 62.
The open and close of anti-skidding charge valve 61, anti-skidding exhaust valve 62 and link valve 51 is worked as institute by the control of brak control unit 5
When having electric braking normal, link valve 51 is in connected state, and brakes is frame control, when certain root spindle motor failure or electricity occurs
Braking is serious slide electric braking by it is removed when, brak control unit 5 will control link valve 51 to enter off-state, brake simultaneously
The pressure for the checking cylinder 10 that control unit 5 can be read according to pressure sensor 9, the brake force applied in single axle is calculated, works as system
When the adhesion coefficient that power needs reaches the adhesion limit set in brak control unit 5, brak control unit 5 can be by the axle
Anti-skidding charge valve 61 is closed, and the anti-skidding charge valve 61 of an axle still can be at open mode in addition.
Explanation is embodied：
Under traction working condition, when an electrical fault occurs, then the traction inversion module 3 of the axle is controlled to cut off the motor, it is whole
Train only loses the tractive force of an axle.
The empty hybrid control strategy of electricity：Electric empty mixing is preferential using electric braking, the control that insufficient section is compensated by air damping
Principle.Air damping can use permutation car mean compensation algorithm（By adhesion limit control）Or trailer is first mended, reach adhesion in trailer
The principle of motor-car is mended after the limit again.According to Principle of Average Allocation, when the electric braking of an axle breaks down, air damping
Will the mean allocation brake force on all axles again, when motor car bogie reaches the adhesion limit, brak control unit 5 stop to
The bogie supplements air damping power, when another axle of bogie where electric braking failure axle reaches the adhesion limit, braking
Control unit 5 closes the charge valve of the axle anti-sliding control valve 6, but the anti-skidding charge valve 61 of failure axle is not closed, the braking control
Unit 5 processed can continue to apply air damping power to failure axle.The principle of anti-sliding control valve 6 is as shown in Fig. 2 with inflation, protect
Pressure, degassing function.According to trailer is first mended, mend the principle of motor-car again after trailer reaches the adhesion limit, then motor occurs
Bogie where the axle of failure is as trailer bogie processing.
Anti-sliding control strategy：Electric braking possesses each independent antiskid control system with air damping, when electric braking detects
Extend certain time to sliding, or air damping detects after seriously sliding that air damping will require that traction control unit 2 is cut
Except the electric braking of sliding axis, after the electric brakings of sliding axis is removed, air damping will recalculate the air system for needing to compensate
Power, air damping power is compensated according to the empty mixed principle of electricity, this control strategy can be avoided because a certain appearance
Sliding for electric braking and the electric braking force for cutting off a bogie or a car, comparatively, air damping is redistributed
When, the axle that sliding occurs in electric braking only needs to undertake the brake force of very little, can so reduce the probability that sliding axis skid again.
Above control strategy can farthest utilize electric braking, reduce brake shoe abrasion, improve vehicle trouble operation ability.
One in units of bogie brak control unit 5 controls two sets of antiskid valves, and brak control unit 5 passes through every axle
The pressure of checking cylinder 10 that upper pressure sensor 9 is read, the adhesion coefficient for applying brake force needs on every axle is calculated, so as to
Realize the empty mixing of electricity and the anti-sliding control of single axle.
This specific embodiment is only explanation of the invention, and it is not limitation of the present invention, people in the art
Member can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but as long as at this
All protected in the right of invention by Patent Law.
