Description
Technical field
The present invention relates to rail vehicle braking technical field more particularly to a kind of linear eddy-current brakes for bullet train
Device.
Background technique
Foundation brake technology is one of key technology of bullet train, since high-speed train braking energy is huge,
Secure parking is realized in defined braking distance and control of slowing down has certain difficulty.Bullet train generallys use more in the world
The composite braking mode that kind mode of braking matches, main mode of braking includes regenerative braking, resistive braking, friction catch, whirlpool
Stream braking, magnetic rail braking and aerodynamic braking etc..China's EMU is using regenerative braking friction fit braking (disc braking)
Mode, this is also in the world using most high-speed train braking modes at present.Both modes will be by between wheel track
Adhesion plays braking action, but under the severe weather conditions such as rain, snow, and wheel track sticks together state variation, influences the hair of brake force
It waves, braking distance is difficult to ensure；With the raising of train speed, rail adhesion coefficient can also be gradually decreased, and lead to high-velocity section
Brake force is insufficient, and braking distance increases, and safety and conevying efficiency can all reduce.
Linear eddy-current brake is a kind of contactless electromagnetic braking mode, is sticked together independent of wheel track, high-velocity section can
Biggish brake force is played, can be not only used for emergency braking, and can be used for service braking, can effectively shorten braking distance, improves row
Vehicle safety, and there is outstanding advantages of no mechanical wear, noiseless, odorlessness, controllable brake force, it can also reduce mechanical system
Dynamic abrasion, performance driving economy is good, especially suitable for high-speed train braking system.
Linear eddy-current brake is also known as High-Speed Eddy Braking, the basic principle is that braking is mounted on railcar with bar magnet
On bogie and it is located at right above rail, the pole N, S of magnet is alternately arranged, and magnetic pole bottom surface and rail surface keep certain work
Acting air gap, using rail as magnetic induction body.Using the relative motion of magnet and magnetic induction body, current vortex is induced in rail
The main field that (being referred to as vortexed), the magnetic field generated by vortex and magnet generate interacts and main field is made to generate distortion, magnetic force
Line deflects, and generates tangential component (i.e. brake force), to make train deceleration, braking energy is converted into the vortex damage of rail
Consumption.Brake force caused by linear eddy-current brake device acts directly on bogie, is not sticked together limitation by wheel track, therefore in height
Fast section has significant braking effect.
From late 1960s, method, moral, Deng state have just carried out application of the eddy-current brake technology on passenger train
Research, and test for many years.Since 2002, linear eddy-current brake device obtained on the ICE3 bullet train of Germany
Batch business application, and achieve good application effect and economic benefit.At present due to the limit of the factors such as technology and cost
System, China not yet realize the engineering application of bullet train linear eddy-current brake.
Linear eddy-current brake device is mainly by electromagnet, support arm, cross-tie, suspension unit and power transmission bar assembly etc. zero
Component composition, wherein electromagnet makes vortex when eddy-current brake is alleviated for establishing electromagnetic field and structural bearing, suspension unit
On bogie, support arm plays the role of vertical positioning and support, cross-tie when eddy-current brake applies for dynamic device hanging
Two groups of eddy-current brake electromagnet are connected as one, power transmission bar assembly is for transmitting eddy-current brake power to bogie.
The self weight of linear eddy-current brake device is larger, and the height of electromagnet is limited by bogie space, leads to hanging down for magnetic yoke
It is limited to rigidity.When in running order (applying braking), under the multiple action of self weight, electromagnetic attraction and vibratory impulse, electricity
Biggish vertical deflection deformation can occur for magnet magnetic yoke, the rail even magnetic that be easy to cause that eddy-current brake power is unstable, magnetic pole collides with
The harm such as pole damage, influence traffic safety.
