Technical field
The present invention relates to a kind of rail vehicle braking system, more particularly, to a kind of high-speed maglev train safety arrestment system
System.
Background technology
Magnetic-levitation train is a kind of modern high technology track vehicle, and the nothing between train and track is realized by electromagnetic force
Contact is suspended and is oriented to, the electromagnetic force tractor-trailer train operation for recycling linear motor to produce.With the raising of train speed, train
Braking energy and speed it is square directly proportional, braking distance is sticked together with speed non-linear growth, and in high speed section wheel track
Power declines, therefore existing high-speed maglev train uses composite braking system to ensure the safety arrestment of train.
The safety arrestment mode that German TR08 types magnetic-levitation train uses is braked for eddy-current brake and sled：When train is promptly made
When dynamic, first using eddy-current brake；When train speed is down to 150km/h, eddy-current brake power greatly weakens, the vortex system of train
Motor magnet is contacted with the braking wearing plate on side, by frictional force brakes；The 10km/h when train speed is down to, closes vortex
Braking system, train put down sled, slide to aid parking point.
Although eddy-current brake is a kind of non adhesion braking mode, but consumption electric energy is big, produces heat height, weight is big, can also
Signal is had an impact, if in dead electricity etc. in emergency circumstances, a large amount of electric energy will be consumed using eddy-current brake, is enabled for making
The stand-by electric energy that train suspends and advances again is reduced.The high-speed maglev train technology that China uses is also often to lead electromagnetic suspension technology,
According to existing train braking system, from the strict sense for be not a kind of safe braking system.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of high-speed maglev train
Sure brake system.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of high-speed maglev train sure brake system, for the safety arrestment of magnetic-levitation train, the system is in magnetic-levitation train
Braked during in high regime using windage, when magnetic-levitation train is in middling speed section using multiple associated with windage braking and friction catch
Braking is closed, friction catch is used when magnetic-levitation train is in low speed segment, until magnetic-levitation train stops.
Preferably, windage braking passes through the windage brake apparatus realization on magnetic-levitation train, friction catch
Realized by the electromechanical brake apparatus on magnetic-levitation train and Magnetically suspended guide rail effect.
Preferably, the brake force that the sum of the wind resistance when windage brake apparatus is opened and magnetic-levitation train running resistance produce
When the deceleration of magnetic-levitation train is not less than the design deceleration of safety arrestment, magnetic-levitation train is in high regime, using windage system
It is dynamic.
Preferably, the wind resistance when magnetic-levitation train speed is not less than 200km/h, and windage brake apparatus is opened is floated with magnetic
When the brake force that the sum of train running resistance produces makes the deceleration of magnetic-levitation train be less than the design deceleration of safety arrestment, magnetic floats
Train is in middling speed section, is combined by adding friction catch with windage braking, and regulation motor tool brake apparatus and Magnetically suspended guide rail
Between active force, make magnetic-levitation train deceleration be equal to safety arrestment design deceleration.
Preferably, when magnetic-levitation train speed is less than 200km/h, windage brake apparatus is disabled, passes through regulation motor tool system
Dynamic active force between device and Magnetically suspended guide rail, makes the deceleration of magnetic-levitation train be equal to the design deceleration of safety arrestment.
Compared with prior art, the invention has the advantages that：
For magnetic-levitation train when high speed stage is run, the thermal capacity limitation of friction catch can not meet the brake request of train,
It cannot be guaranteed that the safety of operation.The high-speed maglev train sure brake system of the present invention is braked in high speed using windage, windage
Braking is a kind of non adhesion braking mode, its brake force and speed it is square directly proportional, there is braking well in high speed section
Effect.
The windage brake apparatus of the present invention can realize unlatching by opening or closing wind wing plate and disable that wind wing plate can
With the design opened using active (power drive unlatching) or passive (by wind-force).
The safety arrestment scheme is braked in the novel friction that middle low speed segment uses and realized by electromechanical brake apparatus, is inherited
The braking thought of conventional friction braking, electromechanical brake apparatus convert electrical energy into mechanical action, and control wearing plate is released simultaneously
Guide rail rail level is compressed, so that produce friction brake force makes train deceleration using frictional force, it is simple and reliable.It is compact-sized, it is small,
It is light-weight；Control performance is good, and precision is high, and response is fast；Energy consumption is low, environment-protecting clean.
By above-mentioned sure brake system, it is tight with most safe most effective way under any abnormal conditions to make train
Anxious emergency, realizes the safety arrestment of high-speed maglev train.

Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of high-speed maglev train sure brake system, for the safety arrestment of magnetic-levitation train 1, the system is in magnetic-levitation train
1 is braked when being in high regime using windage, when magnetic-levitation train 1 is in middling speed section using associated with windage braking and friction catch
Composite braking, friction catch is used when magnetic-levitation train 1 is in low speed segment, until magnetic-levitation train 1 stops.Wherein, windage is braked
Realize that friction catch passes through the motor on magnetic-levitation train 1 by the windage brake apparatus 2 on magnetic-levitation train 1
Tool brake apparatus 3 and Magnetically suspended guide rail effect realization, as shown in Figure 1.
The brake force that the sum of wind resistance and 1 running resistance of magnetic-levitation train when windage brake apparatus 2 is opened produce makes magnetic
When the deceleration of floating train 1 is not less than the design deceleration of safety arrestment, magnetic-levitation train 1 is in high regime, is braked using windage；
Wind resistance and 1 running resistance of magnetic-levitation train when 1 speed of magnetic-levitation train is not less than 200km/h, and windage brake apparatus 3 is opened
The sum of produce brake force make magnetic-levitation train 1 deceleration be less than safety arrestment design deceleration when, during magnetic-levitation train 1 is in
Fast section, is combined by adding friction catch with windage braking, and the effect between regulation motor tool brake apparatus 3 and Magnetically suspended guide rail
Power, makes the deceleration of magnetic-levitation train 1 be equal to the design deceleration of safety arrestment；When 1 speed of magnetic-levitation train is less than 200km/h,
Windage brake apparatus 2 is disabled, by the active force between regulation motor tool brake apparatus 3 and Magnetically suspended guide rail, makes magnetic-levitation train 1
