Abstract

A high-speed motor train unit trailer bogie comprises a wheel pair, a spiral spring group, an axle box, a framework, an air spring, an anti-side-rolling torsion bar, an anti-snaking shock absorber, a central traction, a disc-shaped foundation brake and a swing bolster, wherein a longitudinal beam between two cross beam steel pipes is integrally designed, two ends of the longitudinal beam are provided with brake hanging seats, the middle of the longitudinal beam is provided with a transverse shock absorber seat, a cross side beam connecting seat is designed by adopting a forged piece variable cross section, one end of the cross side beam connecting seat is in butt joint assembly welding with the cross beam steel pipes, and the other end of the; and a rubber spring is arranged below the spiral spring group, and the axle box is connected with the framework through an axle box rubber node. The utility model discloses the rational arrangement and the integration of each module make this trailer bogie have sufficient fatigue strength, sufficient bearing capacity, and the bogie has good vertical travelling comfort and horizontal travelling comfort on straight circuit and curve, has good stability when the high-speed operation, reduces the track effort simultaneously.

Description

The EMU trailer bogie
Technical field
The utility model relates to a kind of EMU trailer bogie, especially relates to a kind of EMU trailer bogie with the above speed operation of 300km/h.
Background technology
Bogie truck is the critical component of railway vehicle, and trailer bogie is meant in the train the not bogie truck of drive.Existing trailer bogie, the strength at repeated alternation of framework is low, and safe reliability is lower during high-speed cruising; One is low with secondary suspension device flexibility, and cushioning ability is poor; Wheel is to location inaccuracy, less stable during high-speed cruising.The existence of the problems referred to above makes existing trailer bogie can not satisfy the requirement of EMU safety and stability operation, makes the high-speed rail transportation system lose the operation economy and the reliability that should have.
The utility model content
Technical problem to be solved in the utility model provides a kind of framework and has enough strength at repeated alternations and load-carrying capacity, one is good with secondary suspension device flexibility, cushioning ability is strong, and wheel is to locating accurate EMU trailer bogie, to overcome the defective that background technology exists.
For solving the problems of the technologies described above, the utility model provides a kind of EMU trailer bogie, comprise that two wheels that have brake disc are right, four coil spring groups, four pivoted arm axle boxes, a welded framework, two air bellows, an anti-side rolling torsion rod, two groups of anti-shock absorbers that crawl, central authorities' traction, one cover dish-type foundation brake, a bolster, each is taken turns the pivoted arm axle box is installed at two ends, pivoted arm axle box top is equipped with the coil spring group, a framework is installed on the coil spring group, the framework top is equipped with two air bellows, air bellow is controlled by levelling valve, the air bellow bottom has the urgent spring of V-shape, central authorities' traction is installed between two air bellows, what play draw is two pull bars, pull bar is the Z font, two are equipped with a bolster above the air bellow, the auxiliary air reservoir of bolster double as air bellow, an anti-side rolling torsion rod and two groups of anti-shock absorbers that crawl are installed between bolster and the framework, anti-side rolling torsion rod and air bellow are linked together, and every side of framework is equipped with two anti-shock absorbers that crawl, framework and wheel between the dish-type foundation brake is installed, it is characterized in that: framework is a H type welded structure, curb girder is a concave shape, and the longitudinal beam between two crossbeam steel pipes is formed and adopted integrated design, across two crossbeam steel pipes, form box type construction, the two ends of longitudinal beam are the braking flap seats, and the centre is the lateral damper seat, and horizontal curb girder Connection Block adopts the design of forging variable section, one end docks assembly welding with the crossbeam steel pipe, and the other end becomes box type construction with the curb girder upper cover plate with the lower cover assembly welding; Coil spring group below is equipped with low rigidity rubber spring, and two air bellows are the Daqu capsule, and the urgent spring of air bellow is a V-shape, makes secondary suspension have relatively low stiffness when air bellow does not have gas; The pivoted arm axle box is connected with framework by the axle box rubber nodal point.
The reasonable Arrangement of each module of the utility model and integrated makes this trailer bogie have enough strength at repeated alternations, enough load-carrying capacitys; One of flexible, balance is that vertical suspension gear and two is the LF device, makes bogie truck have good vertical traveling comfort on level tangent track and curve; Optimize one be, two be that lateral stiffness and two is that horizontal damping makes bogie truck have good horizontal traveling comfort on curve; One of optimization is that registration device adds that the anti-shock absorber that crawls makes bogie truck have good stable when high-speed cruising, reduces rail effect power simultaneously.
Description of drawings
Fig. 1 is an overall structure scheme drawing of the present utility model;
Fig. 2 is a framework structure scheme drawing of the present utility model.
The specific embodiment
With reference to Fig. 1, the utility model is installed in each with pivoted arm axle box 2 and takes turns two ends to 1, be connected with framework 4 by rubber nodal point 12, make wheel, guaranteed the stability of high-speed cruising accurate at location dimension and locating stiffnesses vertical, vertical and horizontal with respect to framework; Four coil spring groups 3 are installed on pivoted arm axle box 2, rubber spring 11 is installed below coil spring group 3, can reduce by one is the rigidity of vertical suspension, and has cushioning effect; A framework 4 is installed on coil spring group 3, two air bellows 5 are installed on framework 4, air bellow 5 is by levelling valve 14 controls, and air bellow 5 bottoms have the urgent spring 13 of V-shape, make that when air bellow does not have gas secondary suspension has relatively low stiffness; Central authorities' traction 6 is installed in the middle of air bellow 5, a bolster 7 is installed on two air bellows 5, an anti-side rolling torsion rod 8 is installed between bolster 7 and framework 4, one group of anti-shock absorber 9 that crawls is installed in framework 4 both sides, dish-type foundation brake 10 is installed at framework 4 with between taking turns 1.
With reference to accompanying drawing 2, framework 4 is the H type, is welded by two curb girders 15 and two crossbeam steel pipes 16, is connected by Connection Block 20 between the horizontal curb girder, Connection Block 20 1 ends dock assembly welding with crossbeam steel pipe 16, and the other end becomes box type construction with curb girder upper cover plate 21 with lower cover 22 assembly weldings.Two 16 of crossbeam steel pipes form integrated box-structure across two longitudinal beams 17, and the two ends of longitudinal beam 17 are braking flap seats 18, and the centre is a lateral damper seat 19.
