The feedback control of position；So that the working condition of all hub motors (2a) is changed into generating state by motoring condition, wheel
The electric current that hub motor (2a) issues flows into lithium battery (6) via electric machine controller (5), charges to lithium battery (6)；In turn
Convert the kinetic energy of empty rail vehicle to by hub motor (2a) electric energy of lithium battery (6), hub motor (2a) quick deceleration is straight
To stopping operating, the middle strength regeneration formula electric braking of small size air rail vehicle is realized；
B3, master controller (10) issue control signal to the control terminal (9a) of relay (9), are connected to relay (9)；Simultaneously
Intensity brake control signal makes intensity braking mode in electric machine controller (5) entrance: motor control in master controller (10) sending
Position of the rotor for the hub motor (2a) that device (5) processed combines Hall sensor (2c) to detect relative to stator, controls motor
The on-off moment of the output end of controller (5), input terminal realizes the feedback control to hub motor (2a) rotor-position；So that
The working condition of all hub motors (2a) is changed into generating state, the electricity that hub motor (2a) issues by motoring condition
Stream, flows through braking resistor (7) via electric machine controller (5), relay (9a)；And then the kinetic energy of car body (4) is passed through into wheel hub electricity
Machine (2a), braking resistor (7) are converted into thermal energy, and hub motor (2a) quick deceleration realizes small size air rail vehicle up to stopping operating
Middle intensity resistance-type electric braking.
4. a kind of method that high-intensitive braking is carried out to small size air rail vehicle using the small size air rail Vehicular brake device,
The practice is:
C1, master controller (10) issue control signal to the control terminal (9a) of relay (9), are connected to relay (9)；
Master controller (10) is simultaneously emitted by high-intensitive brake signal to electric machine controller (5) and electric cylinder (11)；Motor control
The operation of device (5) progress C2 step；Meanwhile electric cylinder (11) carries out the operation of C3 step；
Intensity braking mode in C2, electric machine controller entrance: the wheel that electric machine controller (5) combines Hall sensor (2c) to detect
Position of the rotor of hub motor (2a) relative to stator controls the output end of electric machine controller (5), the on-off moment of input terminal,
Realize the feedback control to hub motor (2a) rotor-position；So that the working condition of all hub motors (2a) is by electronic
State is changed into generating state；The electric current that hub motor (2a) issues flows into lithium battery (6) via electric machine controller (5), simultaneously
Braking resistor (7) are flowed through by relay (9a) again；And then by the kinetic energy of empty rail vehicle, it is converted into the electric energy of lithium battery (6), together
When thermal energy is converted by (6) braking resistor (7)；Hub motor (2a) is slowed down rapidly up to stopping operating, and realizes small size air rail
The middle strength regeneration and resistance-type electric braking of vehicle；
The push rod of output rod promotion hydraulic cylinder (12) of C3, electric cylinder (11)；The hydraulic oil of hydraulic cylinder (12) is squeezed, pressure
The pressure of amplification, amplification drives all brake clamps (8b) by oil inlet pipe, generates strong pinching action, makes all
Brake disc (8a) clamps travelling wheel (2)；Realize the mechanical friction braking of small size air rail vehicle.
