Abstract

The utility model relates to a power bogie which comprises wheel pairs, a spiral spring assembly, axle boxes, a bogie frame, air springs, an anti-rolling torsion bar, anti-yaw dampers, a central retractor, a basic brake and a swing bolster, wherein, the bogie frame is in an H-shaped welding structure; a side beam is in a down concave shape; a transversal side beam connecting base adopts a forging and various section design; one end of the transversal side beam connecting base is in butt joint and assembly welding with beam steel tubes, and the other end is in assembly welding with the upper cover plate and the lower cover plate of the side beam into a box structure; a brake hanger is welded on the outer ends of the beam steel tubes; a transversal damper base is welded on the side beams of the bogie frame; rubber springs with low rigidity are arranged under the spiral spring assembly; the two air springs are big bellows; when the air springs are out of air, secondary suspension has lower rigidity; and the swing axle boxes are connected with the bogie frame through axle box rubber nodes. The utility model has the advantages of enough fatigue intensity, enough bearing capability and favorable vertical comfort and transversal comfort; at the same time, the acting force of a track is decreased.

Description

Power truck
Technical field
The utility model relates to a kind of motor train unit power truck, especially relates to a kind of motor train unit power truck with the above speed operation of 200km/h.
Background technology
Bogie truck is the critical component of railway vehicle, is starting before the motor train unit, and the overall trip speed of passenger train mainly adopts the traction operation way of power concentration below 160km/h, and the day bus bogie truck is drive not, and running velocity is low.In addition, the strength at repeated alternation of existing truck frame 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.In view of this, present bogie truck 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 power truck, to overcome the defective that background technology exists.
For solving the problems of the technologies described above, the utility model provides a kind of motor train unit power truck, 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, one group of 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, 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, an anti-side rolling torsion rod and two groups of anti-shock absorbers that crawl are installed between bolster and the framework, and every side of framework is equipped with two anti-shock absorbers that crawl, framework and the wheel between the dish-type foundation brake is installed, it is characterized in that: framework is a H type welded structure, and curb girder is a concave shape, and the horizontal curb girder Connection Block of curb girder 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; The outer end of two crossbeam steel pipes is welded with the braking flap seat, and the lateral damper seat is welded on the truck side sill; Coil spring group below is equipped with low rigidity rubber spring, and two air bellows are the Daqu capsule, and secondary suspension does not have relatively low stiffness when air bellow has 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 bogie truck 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 the utility model structural representation;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is a framework structure scheme drawing in the utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model is installed in each with pivoted arm axle box 3 and takes turns two ends to 2, and axle box is connected with framework 1, makes wheel to accurate at location dimension and locating stiffnesses vertical, vertical and horizontal with respect to framework, has guaranteed the stability of high-speed cruising; Four coil spring groups 4 are installed on pivoted arm axle box 3, and can reduce by one is the rigidity of vertical suspension, and has cushioning effect; A framework 1 is installed on coil spring group 4, two air bellows 5 are installed on framework 1, air bellow 5 makes that by levelling valve control secondary suspension has relatively low stiffness when air bellow does not have gas; A bolster 8 is installed on two air bellows 5, an anti-side rolling torsion rod 7 is installed between bolster 8 and framework 1, one group of anti-shock absorber 6 that crawls is installed in framework 1 both sides, dish-type foundation brake 9 is installed at framework 1 with between taking turns 2.
With reference to Fig. 3, framework 10 is the H type, be welded by two curb girders 13 and two crossbeam steel pipes 15, connect by Connection Block 11 between the horizontal curb girder, Connection Block 11 1 ends dock assembly welding with crossbeam steel pipe 15, the other end becomes box type construction with curb girder upper cover plate 12 with lower cover 14 assembly weldings, and braking flap seat 16 is arranged on the braking crossbeam, and lateral damper seat 17 is on truck side sill.
