Description
Technical field
The present invention relates to technical field of rail traffic, more particularly, to suitable for wheel track railroad train, urban track traffic
Deng the Auxiliary support and guidance method of wheel track vehicle.
Background technology
Rail railway is taken turns so that its freight volume is big, speed is fast, safe and reliable as logistics means important in national economy, train
And the important vehicles of people's trip.With socio-economic development and scientific and technological progress, wheel track railway technology also obtains
Fast development, more and more important effect is played in the development of the national economy and people's lives.Particularly high-speed railway is fast
Speed development, make people's trip more convenient, effectively strengthen interlocal economic interaction and people-to-people contacts；City rail is handed over
Logical and subway construction is effectively improved and alleviated the pressure of urban public transport；And popularization and the freight rail of railway network
The construction of special line, the flowing of personnel and resource is more effectively strengthened, promotes development of national economy etc..Wheel track railway technology is every
Once progress all effectively promotes the development of social economy and the raising of living standards of the people.
But the basic technical features for taking turns rail railway are trains to travel in orbit, pass through connecing for train wheel and rail
Touch the support for realizing train, guiding and driving operation three zones.Because railroad train loading capacity is big, car body is heavy, at a high speed
The rigid contact of wheel and rail necessarily leads to violent friction, vibration and impact during traveling.This not only needs powerful traction
Power overcomes frictional resistance, and friction and impact make wheel track part quickly wear away, and adds maintenance cost and makes security
Reduce, while wheel-rail impact produces vibration and noise and passenger is felt uncomfortable and cause noise pollution to surrounding environment.Therefore,
It is the target that wheel track railway technology is pursued all the time to reduce resistance, mitigation abrasion and damping noise reduction.
Realizing the technical measures that above-mentioned target is usually taken is：Improve the construction criteria of rail track and the smooth-going of track
Degree, wheel track equipment and mitigation car body weight etc. are manufactured using various damping noise reduction technical measures, using special, wear-resistant steel.

Direct ratio, therefore in traditional wheel-rail technology, reducing frictional resistance, mitigation abrasion and the most direct effective measures of damping noise reduction is exactly
Mitigate the weight of wheel-rail train to mitigate the active force between wheel and rail.Therefore, modern railways particularly passenger rail all courts
Train lightweight direction to develop, high ferro train is even more the high cost that spares no expense, and mitigates car using various new materials, new technology
The deadweight of body, and riding capacity number is limited to mitigate train axle weight, train marshalling list is reduced to reduce resistance, while also using more
Motor-car driving lifting traction power reaches the purpose run at high speed to overcome train running resistance.So one side train is light
Quantify and more motor-cars driving greatly increase train manufacturing cost, and limit riding capacity, reduce train marshalling list again limit row
Car freight volume, unit operation cost is set to remain high.Even if so, the speed of service of High Speed Railway Trains is still without reaching people's
It is expected, and high ferro admission fee is expensive, also allows many ordinary peoples to hang back, this is also the one big of high-speed railway popularization and development
Obstacle.Urban track traffic and subway are because passenger is numerous, densely populated place, the vibration of train and noise so that riding comfort
Greatly lower, ground light rail train also causes noise pollution to circuit both sides environment.These are all that conventional wheel rail railway needs to change
Enter the problem of solution.
