Abstract
A kind of framework of narrow-gauge train bogie, including crossbeam, curb girder, longitudinal beam, air spring mounting seat, anti-side rolling torsion rod mounting seat, checking cylinder flap seat, bogie frame are " H " type structure, it is characterised in that：Crossbeam is solid forging structure with curb girder junction, and the upper hanger and lower hanger for braking flap seat use forging structure.The upper hanger of braking flap seat of the present utility model uses forging structure with lower hanger, saves space relative to welding structure, facilitates the installation of brake disc and checking cylinder；Horizontal curb girder junction is solid forging structure, and framework overall welding deformation is reduced while reducing welding capacity, improves the overall static strength of framework, fatigue strength；In local crucial force part, by increasing the thickness of material, to improve its bulk strength.
Description
Technical field
The utility model belongs to rail vehicle truck technical field, more particularly, to one kind be applied to meter-gage circuit or its
The bogie frame of its narrow gauge.
Background technology
The standard gauge bogie applied at present is gauge 1435mm, by prolonged actual motion, forms maturation
Structure.But because gauge is changed into 1000mm, cause parts space arrangement not enough.Conventional bogie frame crossbeam and
It is welding structure between curb girder, in order to meet dynamic property performance during vehicle operation, intensity life requirements, weld seam area is very big,
The gauge occupied is also increased by, and also conventional braking flap seat is welded together using plurality of steel plates, therefore is also accordingly occupied
Bigger space.This problem annoyings designer always, although attempt to structure type being modified to compact structure,
But, in actual moving process, to reach and not interfere between parts, vehicle run stability is normal, meet vehicle fortune
Dynamic performance during row is difficult to realize.
The content of the invention
The purpose of this utility model is to provide a kind of framework for the passenger car bogie for being adapted to gauge 1000mm narrow gauges,
Prevent from interfering between parts in running, while dynamic property performance, intensity life requirements when meeting vehicle operation.
To achieve the above object, the utility model provides a kind of framework of narrow-gauge train bogie, including crossbeam, curb girder, vertical
Xiang Liang, air spring mounting seat, anti-side rolling torsion rod mounting seat, checking cylinder flap seat, bogie frame are " H " type structure, and its feature exists
In：Crossbeam is solid forging structure with curb girder junction high-stress area, and the upper hanger and lower hanger for braking flap seat use forging
Structure.
The upper hanger of braking flap seat of the present utility model uses forging structure with lower hanger, is saved relative to welding structure
Space, facilitates the installation of brake disc and checking cylinder；Horizontal curb girder junction is solid forging structure, is reduced while reducing welding capacity
The overall welding deformation of framework, improves the overall static strength of framework, fatigue strength；In local crucial force part, by increasing
Plus the thickness of material, to improve its bulk strength.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 upward view.
Embodiment
Reference picture 1, Fig. 2, the utility model framework are mainly made up of following components, 1 curb girder, 2 crossbeams, 3 longitudinal beams,
4 checking cylinder flap seats, 5 air spring mounting seats, 6 anti-snake damper mounting seats, 7 pivoted arm positioning seats, 8 vertical damper mounting seats, 9
Anti-side rolling torsion rod mounting seat, 10 transverse damper mounting seats, 11 drawing pull bar mounting seats.Framework by two box curb girders, two
Tubular crossbeam and a longitudinal welding box beam are formed.Crossbeam is solid forging structure, brake hanging with curb girder junction high-stress area
The upper hanger of seat uses forging structure with lower hanger.Curb girder is the recessed fish belly box-structure in middle part, and upper cover plate is by central cover
Plate and end plate composition.Pivoted arm positioning seat and vertical damper mounting seat, transverse damper mounting seat etc. are welded with curb girder, it is internal
There are 6 pieces of stiffener plates.Crossbeam is connected using two seamless steel pipes with longitudinal beam, and drawing pull bar seat and system are welded with crossbeam
Dynamic flap seat.
