Description
Technical field
The present invention relates to a kind of hanging type aerial track train bogie, belongs to sky rail bogie of car structure-design technique neck
Domain.
Background technology
Empty rail vehicular traffic is one kind of rail traffic vehicles, and its track is box, by steel strut support in the air.Vehicle
Bogie is located in box track, and vehicle is hung on below track by its bogie, is hung and is gone.Empty gauge lines occupation of land is small,
The space that city can be made full use of limited, is suitable for building line in metropolitan bustling center, landscape and sunshine shadow to city
Sound is minimum, and circuit configurations are simpler, and construction investment expense is relatively low, and vehicle can be realized in heavy grade (60 ‰) and small curve half
Safe operation on footpath (30m), this allows for the building that city is can bypass during sky rail vehicle route selection, and vehicle has urban transportation
With the double action gone sightseeing.
At present, the empty rail bogie of car mainly has two kinds of structure types.The first is framework, gear-box, the longitudinal cloth of motor
Put and be rigidly connected, travelling wheel, directive wheel are separately mounted to gear-box, on motor, and suspension gear is by central pin shaft penetrating construction
Bolster is connected, the structure gear case, motor working environment are more severe.It is for second that framework is general frame bearing structure, motor,
Gear-box, directive wheel, brake component are directly connected with framework, and framework lower end extension errant simultaneously sets secondary suspension, this turn
To the connecting interface of frame and car body is more, structure is more complicated.
Such as the A of Chinese invention patent application CN 104442880, " a kind of suspension monorail bogie ", car are disclosed
The lower section of bogie is hung on by hanging draw-gear, it, which hangs draw-gear, includes centrepin and bolster, its centrepin
Upper end is fixed with turning undercarriage bottom, and lower end and the bolster upper end of centrepin are fixed, and setting is waved under damper, bolster in both sides
End is then directly rigidly fixed with vehicle to be connected, so as to realize the hanging operation of vehicle.The structure belongs to second of structure shape above
Formula.
The content of the invention
The technical problems to be solved by the invention are to overcome the disadvantages mentioned above of prior art there is provided a kind of hanging type aerial
Track train bogie.
In order to solve the above technical problems, the hanging type aerial track train bogie that provides of the present invention, including framework, OK
Walk wheel, motor, bolster and the centrepin of driving road wheel, it is characterised in that：The bolster is arranged at framework by flexible member
The top at middle part, the upper end of centrepin is connected with bolster, and the lower section of centrepin sets suspension gear, the suspension gear be used for and
Car body is fixedly connected.
Further, the motor is installed on the front and rear sides of framework, drives the walking of respective side by gear-box respectively
Wheel, road wheel is connected with gear-box, and gear-box is fixed on frame underneath so that bogie is arranged at walking by the gear-box
Wheel top is simultaneously supported.
Bolster is arranged at top in the middle part of bogie by bogie of the present invention by flexible member, and car body passes through suspension gear
It is connected with centrepin with bolster, realizes that vehicle is lifted on the lower section of bogie.The bogie structure is novel, and mounting interface is less,
Bolster reasonable stress, is conducive to the stable operation of vehicle.
In addition, the motor for the road wheel of driving is divided into the two ends of bogie, the casing that bogie passes through gear-box
It is supported.So that bogie structure is compact, and the support strength of bogie results in guarantee, and the operation for improving vehicle is steady
Qualitative and riding comfort.
