Abstract
The utility model relates to a bogie truck framework which comprises two side beams, two crossbeams and a longitudinal beam arranged between the two crossbeams. Positioning seats are fixed under the side beams, and air spring seats are fixed above the side beams; both ends of each side beam are fixed with vertical oscillating damper seats, the inner side of each side beam is fixed with a lateral oscillating damper seat, and the outer side of each side beam is fixed with an anti-snake movement oscillating damper seat; the outer side of each crossbeam is fixed with a brake hanger, the inner side is fixed with a pulling draw rod seat, anti-roll torsion bar seats are fixed under both ends of each crossbeam, and the crossbeams adopt seamless pipe structures; the longitudinal beam forms a box-shaped swallowtail structure. The bogie truck framework avoids the appearance of a large stress area to control the stress level in the allowable range of strength and completely meets the requirements in the conditions of various domestic lines and the operating requirements of 160 kilometers per hour.
Description
Technical field:
The utility model relates to railway passenger car bogie, especially relates to a kind of truck frame.
Background technology:
Bogie truck is a passenger train traveling portion, and framework is the agent structure part of bogie truck, is welded with the various flap seats of bogie truck one, secondary suspension and braking on framework.What influence the panel work performance mainly is the structural strength and the anti-fatigue performance of framework.The overall construction intensity of framework plays key role to the speed-raising of passenger train.From the phase at the end of the nineties in last century, the China railways passenger vehicle has raised speed to 160km/h, and the framework structure fatigue problem successively appears in several bogie trucks of release.Can't satisfy the requirement of 160km/h speed class operation.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of structure optimization, reduces and avoid the appearance of high-stress area, and the truck frame that the whole anti-fatigue performance of truck frame is improved greatly is to overcome the defective that background technology exists.
The technical solution of the utility model is: comprise the longitudinal beam between two curb girders, two crossbeams and two crossbeams, be fixed with positioning seat below the curb girder, be fixed with the air bellow seat above, the curb girder two ends are fixed with the vertical damper seat, the curb girder inboard is fixed with the lateral damper seat, the curb girder outside is fixed with the anti-damper base that crawls, the crossbeam outside is fixed with the braking flap seat, the inboard is fixed with the drawing pull bar seat, be fixed with the anti-side rolling torsion rod seat below the crossbeam two ends, crossbeam adopts the solid drawn pipe structure, and longitudinal beam is a box-shaped dovetail structure.
The utility model crossbeam has replaced the box type construction that is welded by four block plates by solid drawn pipe, and not only bulk strength does not reduce, and has reduced a lot of weld seams, and structural machinability also improves greatly; Longitudinal beam changes box-shaped dovetail structure into by former " fourth " font structure, has improved the overall construction intensity and the rigidity of framework greatly.By above-mentioned optimal design, avoided the appearance of high-stress area, the stress level of integral frame is controlled in the scope that intensity allows, can satisfy the operating needs of 160 kilometers of domestic various different line conditions and speed per hours fully.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
With reference to accompanying drawing, the utility model comprises the longitudinal beam 4 between two curb girders 1, two crossbeams 3 and two crossbeams, be welded with positioning seat 2 below the curb girder, be fixed with air bellow seat 11 above the curb girder, the curb girder two ends are fixed with vertical damper seat 7, the curb girder inboard is fixed with lateral damper seat 8, the curb girder outside is fixed with the anti-damper base 10 that crawls, the crossbeam outside is fixed with braking flap seat 6, the inboard is fixed with drawing pull bar seat 5, be fixed with anti-side rolling torsion rod seat 9 below the crossbeam two ends, crossbeam 3 adopts the solid drawn pipe structure, and longitudinal beam 4 is a box-shaped dovetail structure.
