The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Fig. 1～2, plant standard gauge apart from controllable type bogies for railway vehicles, comprise that front and back wheel is to 1, two groups of bogie side frames 2, a bolster 7 and two groups of central mounting springs 10, described two ends of taking turns 1 are provided with antifriction-bearing box 9, the two ends drawing strickle guide of described bogie side frame 2 is carried on antifriction-bearing box 9 by adapter 3, the two ends of described bolster 7 are arranged on central mounting spring 10, described central mounting spring 10 is arranged in the central square frame of described bogie side frame 2, bolster 7 both sides on described central mounting spring 10 tops are provided with shock attenuation unit 6, the damper spring pair that shock attenuation unit 6 comprises the wedge body 17 of hollow and sets within it, described damper spring pair consists of spring 16 in the outer spring 15 of coaxially arranged vibration damping and vibration damping, spring 16 one end and bolster 7 butts in the outer spring 15 of described vibration damping and vibration damping, spring 16 other ends and wedge body 17 inner cavity top butts in the outer spring 15 of described vibration damping and vibration damping, described wedge body 17 is provided with oblique friction face a and vertical friction face b, described oblique friction face a contacts with the Eight characters face of bolster 7, described vertical friction face b contacts with the column wearing plate 18 on bogie side frame 2 central square frame sidewalls.The angle of described oblique friction face a and vertical surface is 37.5 °.Described bolster 7 both sides, top are provided with bottom side bearing 11, and bottom side bearing 11 is the long stroke elastic side bearing of normal contact, and it comprises side bearing box 14, side bearing lid 12 and elasticity lining post 13, and described elasticity lining post 13 is arranged in the cavity consisting of side bearing box 14 and side bearing lid 12.Saddle resilient sleeper-bearing 4 and U-shaped drawing strickle guide wearing plate 5 are also installed between described adapter 3 and bogie side frame 2, described saddle resilient sleeper-bearing 4 is arranged on adapter 3, described U-shaped drawing strickle guide wearing plate 5 is welded on bogie side frame 2, and described U-shaped drawing strickle guide wearing plate 5 bottoms and saddle resilient sleeper-bearing 4 are accepted.
As shown in Fig. 3～6, shock attenuation unit 6 is arranged on bolster 7.Relative bolster upward movement under the effect of wedge 17 spring 15 and pre-compression force of spring in vibration damping 16 outside vibration damping.But have a bevel friction pair between bolster 7 and wedge 17, under the guiding of bevel friction pair, the upward movement of wedge 17 produces cross motion trend to the right, 18 of wedge 17 friction faces and side frame column friction plates are closely reclined and form facade friction pair.Like this, the vertical force that damper spring produces power forms a conicity force F under the effect of oblique friction face a, and this component just becomes the positive pressure F between wedge 17 and column friction plate 18.When bolster 7 drives wedge 17 up-down vibration, under positive pressure F effect, 18 of wedge 17 and column friction plates produce friction, so just Vehicular vibration ability can be converted into frictional heat energy and consume, thereby eliminate Vehicular vibration.
Be positioned at bolster 7 connects position central mounting 10 with bogie side frame 2 and be comprised of the D7 cylindrical steel spring assembly that meets AAR standard, each spring assembly comprises spring 20 in the outer spring 19 of the carrying of two stage stiffness and carrying, carry outer spring higher than carrying interior spring.Central mounting 10 is comprised of 9 groups of spring assembly that comprise spring 20 in the outer spring 19 of carrying and 5 groups of carryings.
So-called two stage stiffness refers to: when vehicle load hour, bogie truck is only by outer spring 19 carryings of higher carrying, the rigidity of whole suspension is little; When vehicle load is larger, to carry the further compression of outer spring 19 and jointly carried by the outer spring 19 of carrying and the interior spring 20 of carrying, the rigidity of whole suspension is larger.The damper spring pair of shock attenuation unit 6 is also same principle.
As shown in Figure 7, during long stroke elastic side bearing 11 work, the long stroke elastic side bearing 11 of car body body side bearing compression, utilizes the precompressed elastic force of elasticity lining post 13 to form positive pressure between body side bearing and bottom side bearing lid.When bogie truck and car body relatively rotate, required moment of gyration when car body body side bearing and bottom side bearing lid contact surface produce friction force and form on vehicle straight line high-speed cruising; When vehicle passes through curve, car body under centrifugal force sidewinders, and at this moment leans on the body side bearing in curve outside with the long stroke elastic side bearing 11 of the further compression of sidewindering of car body, elasticity lining post 13 is moved down, until kill.Can prevent that so again elasticity lining post 13 from being caused steering resistance square excessive by body side bearing excessive compression, is beneficial to curve passing through and passes through.
As shown in Figure 8, Figure 9, adapter 3 is arranged on bogie side frame 2 drawing strickle guide positions and coordinates with rolling bearing system 9.During adapter 3 work, top saddle resilient sleeper-bearing 4 and U-shaped drawing strickle guide wearing plate 5 make adapter 3 with bogie side frame 2 at drawing strickle guide position without abrasion, increase the service life of adapter and bogie side frame, extend maintenance cycle.Saddle resilient sleeper-bearing 4 can provide longitudinal rigidity, realizes the elasticity location of adapter, makes bogie truck have good curving performance.
