Abstract
An air spring truck frame without a swing bolster comprises two side beams, two crossbeams, and a longitudinal beam as well as a locating seat between the two crossbeams, an air spring seat, a vertical shock absorber seat, a lateral shock absorber seat, an anti-wandering shock absorber seat, a brake lifting seat, a draw bar seat, an anti-side rolling torsion bar seat and an anti-overshoot seat; the connection position of the crossbeams and the sides beams is provided with a lateral-side beam connecting seat for transition; and the anti-wandering shock absorber seat and the anti-overshoot seat are welded on the crossbeams of the frame. In the utility model, the lateral-side beam connecting seat is adopted for transition at the large stress block at the connection position of the crossbeams and the side beams of the frame, thus avoiding the original welding lines, and leading the fatigue resistance at the position to be improved greatly; and the anti-wandering shock absorber seat and the anti-overshoot seat are welded on a vertical plate and a lower cover plate originally, but now welded on the crossbeams of the frame, thus greatly improving the stress state of the anti-wandering shock absorber seat and the anti-overshoot seat, leading the whole stress level of the frame to be controlled in the range allowed by material strength, and completely meeting the service requirement of various line conditions at home and abroad and speed of 160 kilometers per hour.
Description
Technical field
The utility model relates to the bogie truck in railway traffic passenger transportation field, especially relates to a kind of framework of swing-bolster-free air spring bogie truck of the 160km/h of being suitable for speed class.
Background technology
Bogie truck is a passenger train traveling portion, and framework is the main body carrying structure of bogie truck.On framework, be welded with various flap seats such as lifting bogie truck one, secondary suspension and braking.High-stress area during vehicle operating on the framework mainly is distributed in the various flap seats position of welding on framework horizontal stroke, curb girder junction and the framework.The crossbeam that present domestic bogie truck is generally taked framework and curb girder directly dock to contact and carry out welding processing and form.But when train was specifically runed, the situation of this place's weld stress concentration was obvious, and weld fatigue intensity is low; Resist and crawl damper base and prevented that red seat was welded on the riser and lower cover of truck side sill, fatigue resistance is low.
Summary of the invention
It is more reliable that technical problem to be solved in the utility model provides a kind of structure, the truck frame that anti-fatigue performance improves greatly.
For solving the problems of the technologies described above, the utility model provides a kind of swing-bolster-free air spring truck frame, comprise longitudinal beam, positioning seat between two curb girders, two crossbeams and two crossbeams, air bellow seat, vertical damper seat, lateral damper seat, anti-snakelike damper base, braking flap seat, drawing pull bar seat, anti-side rolling torsion rod seat and prevented red seat, it is characterized in that: horizontal, curb girder junction is provided with the transition of horizontal curb girder Connection Block, resists and crawls damper base and prevented that red seat was welded on the truck transom.
The utility model adopts the transition of horizontal curb girder Connection Block at the horizontal stroke of framework, the high-stress area of curb girder junction, has avoided original weld seam, and the fatigue resistance at this place is improved greatly; The anti-damper base and prevented that red seat was welded on the truck transom by changing on former riser that is welded on truck side sill and the lower cover of crawling, both strained conditiones have been improved greatly, the integrated stress level of framework is controlled in the scope that strength of material allows, can satisfies the operating needs of 160 kilometers of various different line conditions in home and abroad 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 two curb girders 1, longitudinal beam 3 between two crossbeams 2 and two crossbeams, be welded with positioning seat 4 below the curb girder, be fixed with air bellow seat 5 above the curb girder, the curb girder two ends are fixed with vertical damper seat 6, the curb girder inboard is fixed with lateral damper seat 7, beam-end is fixed with anti-snakelike damper base 8, the crossbeam outside is fixed with braking flap seat 9, the crossbeam inboard is fixed with traction seat 10, the crossbeam bottom is fixed with anti-side rolling torsion rod seat 11, crossbeam top is fixed with anti-red seat 12, horizontal curb girder junction has increased horizontal curb girder Connection Block 13, anti-snakelike damper base on the while framework, prevented red seat, positioning seat and traction seat are changed into by welded-steel plate construction and forging and the smithwelding structure, the axle box damper base changes forging structure into by cast structure, the defective of effectively having avoided welding and casting to produce.
