Technical field
Retarder, auxiliary braking, rolling stock and other rail vehicle retarding brakings, aircraft landing be sliding run retarding braking,
Energy-saving and emission-reduction.
Background technique
China is in the initial stage of technological change, industry transformation active period at present, and rolling stock is as a pillar of the economy
Industry, is also carrying out technological change, and the development of bullet train is badly in need of advanced technology also to improve its performance, aircraft carrier it is short
It is also required to advanced technology away from landing, eliminates old technology, hoisting device performance, energy-saving and emission-reduction are an extremely urgent tasks.
Prior art at present: Electro magnetic Track Brake Equipment for Railway and linear electromagnetic eddy current braking device.Electro magnetic Track Brake Equipment for Railway
Using electromagnet, suction pressure is on rail after energization, friction catch, energy consumption.Linear electromagnetic eddy current braking device utilizes electromagnet, leads to
Alternation vortex is generated after electricity on rail, eddy-current loss makes kinetic energy be converted into heat energy dissipation to fall, reach retarding braking purpose, such
Technology will consume a large amount of electric energy, and fever is serious.
I previously it is proposed that several magnetic force retarders technical solution, that plays the same tune on different musical instruments is wonderful, for refering to.
Summary of the invention
The present invention is directed to bullet train complemental brake system, proposes the solution of planetary roller screw Linear magnetic force retarder
Certainly scheme.It is different according to the structure of planetary roller screw Linear magnetic force retarder, it is divided into A type planetary roller screw Linear magnetic
Power retarder, Type B planetary roller screw Linear magnetic force retarder, c-type planetary roller screw Linear magnetic force retarder and D type
Planetary roller screw Linear magnetic force retarder.
Planetary roller screw Linear magnetic force retarder is close with the principle of linear electromagnetic eddy current braking device, planetary roller
Screw rod type linear magnetic retarder replaces existing linear electromagnetic eddy current braking device technology with the permanent magnetic field that permanent magnet generates
The induced magnetic field of armature winding generation is used the power on, to improve auxiliary braking performance, save electric energy and simplify slow
Device structure is conducive to the lightweight of retarder.
The application field of planetary roller screw Linear magnetic force retarder is not limited only to bullet train, common passenger traffic column
All planetary roller screw Linear magnetic force retarder can be used to carry out assisted deceleration system for vehicle, goods train, subway, light rail and aircraft etc.
It is dynamic.
Detailed description of the invention
Fig. 1, Fig. 2, Fig. 3 show the schematic diagram of planetary roller screw Linear magnetic force retarder.Fig. 1 is main view, figure
Middle label 1 is permanent magnet, and 2 be barricade, and 3 be magnet positioning plate, and the part based on label 1,2,3 adds fastening screw
Etc. constituting magnet fixed plate component.Fig. 2 is A-A cross-sectional view, clearly illustrates the pole N in figure and the pole S permanent magnet is alternately arranged, and is used
To generate the permanent magnetic field of alternately variation.Fig. 3 is B direction view, because rail is relatively narrow, so the single-row arrangement of permanent magnet, when for flying
When machine, can multiple row arrangement, run retarding braking for short landing of the aircraft on aircraft carrier to be sliding, civil aircraft is in use, can be in race
One layer of sheet metal is laid on road.
Fig. 4, Fig. 5 show A type planetary roller screw Linear magnetic force retarder, by 12 planetary roller screw of label in figure
Component (being made of lead screw, nut and roller etc.) and 13 driving motor of label form longitudinal extension mechanism, increase the use of wearing plate 9
With friction catch, wearing plate 9 uses nonferromugnetic material.When retarding braking, longitudinal extension mechanism controls magnet fixed plate component
It moves downward, wearing plate 9 is pressed on rail, the permanent magnet on magnet fixed plate component forms the permanent-magnet magnetic of opposite variation
, permanent magnetic field causes inductive loop on rail, and alternately the eddy current of variation generates induced magnetic field, induced magnetic field and permanent-magnet magnetic
Field intercouples to form magnetic coupling braking, and wearing plate 9 and Rail Surface form friction catch, magnetic coupling braking and friction
Braking is combined into a kind of composite braking.Fig. 5 show D-D cross-sectional view, the length and longitudinal extension machine of magnet fixed plate component
The group number of structure according to it needs to be determined that.
Fig. 6 show Type B planetary roller screw Linear magnetic force retarder, and organization plan relative to Fig. 4 increases
Leakage field protective device.Leakage field protective device is made of transversal stretching mechanism and magnetic leakage shielding plate 8.Transversal stretching mechanism is by label
The composition such as 6 driving motor of 5 planetary roller screw components and label.When retarding braking, transversal stretching mechanism moves magnetic leakage shielding plate 8
It opens, magnetic coupling is made to play a role.
Fig. 7 show c-type planetary roller screw Linear magnetic force retarder, low suspension is used for, directly by magnet fixed plate
Component and leakage field protective device composition.Such technical solution requires assembly precision high.
Fig. 8 show D type traveling star roller screw Linear magnetic force retarder, for high suspension, directly by magnet fixed plate
Component and longitudinal extension mechanism composition.When without retarding braking, magnet fixed plate component is far from rail, magnetic coupling braking
It does not play a role.
Fig. 9 show the scheme that Type B planetary roller screw Linear magnetic force retarder is arranged symmetrically, solid using two column magnets
The transversal stretching mechanism of the structure type of fixed board component, the left and right sides shares a driving motor.Since railroad track has two
Rail, so being arranged symmetrically using planetary roller screw Linear magnetic force retarder to increase auxiliary braking effect.Other types
Planetary roller screw Linear magnetic force retarder the scheme being arranged symmetrically can be used.
