Description
Technical field
The utility model is related to railway goods train bogie technical field, and in particular to and scooter 160km/h when a kind of~
200km/h railway red ball bogie framework.
Background technology
Railway goods train bogie mainly has three-piece bogie and framework type bogie.Wherein, three-piece bogie
The shortcomings of there is smaller diamond resistant rigidity, big unsprung mass and relatively difficult installation disc-brake, it is difficult to surpass to make its speed of service
Cross 120km/h, and framework type bogie then has the advantages that diamond resistant rigidity is big, unsprung mass is small, the dynamics of framework type bogie
Performance is substantially better than three-piece bogie.The rapid speed freight car bogie framework of conventional belt shaketable is led with bolster hanger, longitudinal direction
The part such as bar connected mode that is pulled all be employ bearing pin connection structure, by one section operation after, because abrasion the reason for
So that its dynamic performance and part reliability decline, and when bolster trapeze fails, bolster will fall off in hair on track
Raw security incident.And be mainly used in using the fast steering frame without shaketable bolster overhead on passenger train, secondary suspension one
As use air spring, framework must set auxiliary air reservoir, and structure is more complicated, and manufacturing cost is higher, and corresponding bearing capacity
It is relatively low, 16.5t and the requirement with lower axle weight can only be adapted to, it is impossible to adapt to the use requirement of railway freight-car.
Chinese utility model patent (publication number CN 201116125, publication date 2008.09.17) discloses a kind of bogie
Framework, the framework includes being fixed with positioning seat below the longitudinal beam between two curb girders, two crossbeams and two crossbeams, curb girder, above
Air spring seat is fixed with, curb girder two ends are fixed with vertical damper holder, and side rail inner is fixed with outside horizontal damper holder, curb girder
Side, which is fixed with below anti-snakelike damper base, crossbeam two ends, is fixed with anti-side rolling torsion rod seat, and crossbeam uses seamless steel pipe structure, indulges
It is box-shaped dovetail configuration to beam.
Chinese utility model patent (publication number CN 202213591U, publication date 2012.05.09) discloses a kind of light weight
Change welded bogie, the framework includes a pair of curb girder compositions, a pair of beams compositions.Described curb girder composition has hollow
Body structure, includes a pair of upper and lower cover platess being welded to form and a counter-lateral quadrents web；Described crossbeam composition, which includes, to be run through
Sidepiece web and a pair of the hollow steel pipes welded with sidepiece web；In steel pipe both side ends and the outside of sidepiece web,
A pair of air spring support beams are installed by welding with, air spring support beam has hollow body structure.
Above-mentioned patent structure is substantially similar, and its curb girder is more straight, and air spring mounting platform is provided with the middle part of curb girder, main
To be applied to the rail vehicle of swing-bolster-free air spring bearing mode, and existing Railway Freight Car Repair condition can not meet air bullet
The maintenance requirement of spring, based on the main bearing mode carried jointly with cartridge and side bearing of current railway freight-car, when using it is above-mentioned specially
During sharp disclosed framework scheme, will appear from bolster and secondary suspension device arrangement space it is not enough the problem of, it is impossible to ensure vehicle
Hitch highly meets standard requirement；
