Description
Technical field
The utility model is related to technical field of rail traffic, and in particular to the empty iron hanger of releasable car body.
Background technology
Empty iron, i.e. hanging type aerial monorail traffic system, it is different from subway and tramcar, the track of empty iron on the top,
It is suspended from a kind of track traffic run on overhead rail.With the transition in epoch, urbanization process is constantly accelerated, therefore,
City size is grown rapidly.It is sharply increased with the quickening pace of modern life with urban population quantity, the travel amount of people is increasingly
Greatly, the increase of this travel amount, it is not limited in single city, but have diffused between city and rural area, city and
Between city.Existing traffic can not meet the trip of people, and there is different degrees of automobile congestion phenomenon in each big city in the world.
Therefore, people always search for various modes to solve the caused traffic jam issue of growing travel amount.Due to
Empty rail train by traffic above-ground move in the air, based in process of construction on ground building facilities influence it is small, open rear train operation
Speed is fast, track move towards to be laid with flexibly, advantages such as environmentally safe in operational process, therefore it is in many cities, city and
Rapid development has been obtained between city.Since setting is maked somebody a mere figurehead in empty rail road, vehicle is hung at the lower section of track, therefore for sky
The trailer system of rail train is different from the trailer system of conventional train bottom, it is desirable that the trailer system of empty rail train is small, leads
Draw traction electric machine good heat dissipation effect in system, further optimization can be China's sky rail due to the trailer system of empty rail train driving
More solid foundation is established in the further development of train.
