The utility model relates to a kind of improved railway goods train bogie axle box spring suspension device, this device is used to realize the elasticity location of axle box, further improve the dynamic performance of vehicle, more effectively improve the stationarity of vehicle operating, reach the purpose that prolongs vehicle component and rail service life.Belong to one of technical measures that improve the railway truck drive ability.
Lorry is in service, the load of vehicle be by bolster → pillow spring → bogie side frame → adapter → bearing reach the wheel right.Be used for retraining the axle box suspension gear of wheel to relative position between, the framework, its shape, structure take turnss right constraint control and suppress to take turns right serpentine locomotion all playing an important role to taking turns right location.Majority is that rigid axle case hangs between China railways lorry bogie side frame and the adapter.Because this rigid suspended cushion that is not provided with, easily produce the rhombus dislocation between the side frames in the vehicle operating, this rhombus dislocation will cause the critical speed of vehicle to reduce, and vehicle resonance easily takes place, thereby make the horizontal force between the wheel track strengthen the abrasion aggravation that causes between wheel track.When particularly vehicle moves on curve and since the dislocation of the rhombus of bogie truck will make wheel to and track between produce the bigger angle of attack and bigger guidance force, not only quicken the abrasion of wheel track, even can cause vehicle derailing.Chinese patent: " supporting and the elastic shear pad in the roller bearing adapter stabilizer bar bogie side frame elasticity " (ZL942209699) discloses a kind of axle box spring suspension device, this device has designed a kind of taper rubber metal pad as one of critical component of realizing the axle box resilient suspension, the rubber metal pad of this taper, because righting moment is little, can not more effectively satisfy the requirement of vehicle to lateral stability.
The purpose of this utility model is that design a kind ofly can more effectively be satisfied the axle box spring suspension device of vehicle to the lateral stability requirement than the disclosed axle box spring suspension device of ZL942209699, makes vehicle keep good riding quality.
Technical solutions of the utility model be to the disclosed taper elastic caoutchouc of ZL942209699 heap improve promptly in roller bearing adapter stabilizer bar, keep original bogie side frame elasticity spanner in, change the taper rubber metal pad between bogie side frame and the supporting saddle into the splayed resilient rubbber cushion, like this, the bogie side frame elasticity spanner of former setting still works to increase the anti-rhombus dislocation of bogie truck, and the axle box spring suspension device that adopts the splayed rubber pad connects the impact that can more effectively relax between the wheel track, improve the tractive performance of vehicle, smoothly by curve and the abrasion that reduce wheel track.
Selecting the longitudinal and transverse rigidity of axle box of appropriate design is the key that can the utility model reach promising result.This requires the utility model can select vertical stiffness to satisfy the requirement to vertical deflection easily; Require tractive performance to have related parameter to adjust easily, obtain vertical, the lateral stiffness of demand; Require elastic positioning structure stable and have a bigger rotation righting moment.Promptly in order to implement low wheel-rail force, the Rubber Parts that the axle box spring suspension device is used not only requires to have good positioning, and requires to have certain vertical natural bow value and suitable vertical, located lateral rigidity.
In the design, find to adopt the flat rubber pad, obtain bigger lateral stiffness, vertical deflection is just very little, expect high camber, the thickness thickening, and lateral stiffness just reduces, and therefore is difficult to reach the requirement that not only increases vertical deflection but also improve longitudinal and transverse rigidity.If select the cone rubber heap for use, it is less that it rotates righting moment around bearing spindle, and the lateral stability of vehicle is poor.So the utility model designs a kind of splay rubber pad.This splayed rubber pad has bigger vertical deflection, lateral stiffness, longitudinal rigidity and around the rotation righting moment of X-axis, Y-axis, Z axle, can realize the resilient connection of axle box better: can more effectively relax the impact between the wheel track, improve the tractive performance of vehicle and suppress the right serpentine locomotion of wheel, be beneficial to the abrasion that vehicle waltzs through curve, reduces wheel track.
Below in conjunction with drawings and Examples the utility model is further described:

Fig. 7: the critical speed of bogie truck and shear rigidity Ks and bending stiffness Kb graph of a relation.
The utility model is by bogie side frame 1, adapter, elastic caoutchouc spare and be pressed with the right antifriction-bearing box 5 of wheel and form, it is characterized in that the elastic caoutchouc spare 3 between bogie side frame 1 and the bearing 5 is splay rubber pad; Splay rubber pad 3 is that the splayed rubber bodies 7 of one, last 6 times liner plates 8 of liner plate constitute by sulfuration; Last liner plate 6 usefulness general steel plates are pressed into, and are welded with locating dowel pin 9 on it and are used for being assembled together with the last liner plate 6 equiform lower surfaces of going up adapter 2; Following liner plate 8 usefulness general steel plates are pressed into, and are welded with locating dowel pin 10 on it, are used for being assembled together with the upper surface of the equiform following adapter 4 of following liner plate; The lower surface of following adapter 4 is processed with the cambered surface that matches with bearing 5 is contained on the bearing 5 its seat, and the two sides E of following adapter 4 leads the assembling of platform 1-1 gap by its upper rail 4-1 and bogie side frame 1; The last plane C of last adapter 2 is that spill contacts with bogie side frame 1 cushion cap face, and C face central authorities are welded with locating dowel pin 14 and connect assembling with bogie side frame 1, leaves the gap between two ramp D of last adapter 2 and bogie side frame.
If the axle box locating stiffness of bogie truck: laterally for Kx, vertically for the available two-wheeled of this connection of Ky between bending stiffness Kb and shear rigidity Ks represent, the two-wheeled that the vertical and horizontal rigidity of suitably choosing the splayed configuration rubber pad can make bogie truck between produce suitable shear rigidity Ks and bending stiffness Kb.
So the utility model can pass through hardness, thickness, the physical dimension of the rubber bodies 7 of change resilient rubbber cushion 3, adjust vertically, lateral stiffness and deflection value, satisfy requirement, make it that curving performance and vertical, horizontal power performance preferably be arranged the different dynamic parameter; As change the wrap angle sigma of Eight characters face and bearing 5, can make the focus of elastic axis of three faces of rubber pad 3 meet at the below of bearing, with guarantee elastic support have bigger anti-ly sidewinder, antidive, anti-yawing ability and recovery coefficient, can more effectively suppress to take turns right serpentine locomotion.
If bearing 5 as rigid body, and is had X, Y, three direction main shafts of Z, Rubber Parts is bearing on the bearing 5, when bearing 5 along X, Y, Z axle and when X, Y, Z axle rotate, rubber parts will produce recuperability and righting moment, and its recovery coefficient has K11, K22, K33, K44, K55, K66, calculate by formula, the K66 ≈ 0 of flat rubber pad, K44 are negative value.And splayed rubber pad 3 recovery coefficients around X-axis on the occasion of, around the Z axle bigger numerical value is arranged.
Certain heavy 23 tons of bogie truck are with flat rubber pad, taper rubber metal pad and splayed rubber pad, and the recovery coefficient contrast is as follows:
Table 1
| Recovery coefficient | The plane pad | Eight characters pad | The taper rubber pad |
| K11 kgf/cm | 3140 | 3190 | 2700 |
| K22 kgf/cm | 3140 | 7400 | 2700 |
| K33 kgf/cm | 140230 | 24420 | 13000 |
| K44 kgf/cm | -1133540 | 119780 | -667000 |
| K55 kgf/cm | 1133540 | 12360 | 667000 |
| K66 kgf/cm | ≈0 | 514440 | ≈0 |
| Amount of deflection (mm) | 1-2 | 5-8 | About 8 |
As known from Table 1, though the plane pad has bigger longitudinal and transverse rigidity, vertical deflection little (being generally 1-2mm), and to rotate recovery coefficient K44 around X-axis be negative value, around Z axle rotation recovery coefficient K66 very little (≈ 0).Though conical rubber metal pad has bigger winding degree and longitudinal and transverse rigidity, but rotating recovery coefficient K44 around X-axis is negative value, rotation recovery coefficient K66 very little (≈ 0) around the Z axle, have only the splayed rubber pad both to have bigger vertical deflection, bigger longitudinal and transverse rigidity (K22, K11) is arranged and again around the gyro rigidity (K55, K66) of Y-axis and Z axle.And its anti-rotation rigidity of conical axle box rubber metal pad is little, can not suppress better to take turns right hunting, tests its critical speed and is about 90km/h, and lateral performance is still satisfied inadequately.So plane and conical Rubber Parts all can not suppress to take turns the right operation of crawling completely effectively, improve the abrasion of tractive performance, curving performance and the reduction wheel track of bogie truck.And the utility model design-calculated splayed configuration resilient rubbber cushion, its vertical deflection value can reach 5-8mm, and the hunting critical speed can reach 140km/h, can improve the bogie truck tractive performance effectively and reduce wheel-rail wear.
The power property arguments of the splayed rubber blanket of the utility model design is decided by hardness, thickness, geometric parameter, the wrap angle sigma of rubber blanket, adjusts above-mentioned factor and can obtain required longitudinal and transverse rigidity and deflection value. Make its existing preferably curving performance, higher critical speed is arranged again. As change the wrap angle sigma of Eight characters face and bearing, and can make three surface elastic main shaft focuses of rubber blanket 3 meet at the below of bearing, to ensure larger anti-rotation restoring moment, better suppress the right hunting of wheel. So the utlity model has and to select easily and adjust its vertical stiffness, reach required winding degree, the advantage that requires to satisfy low wheel rail force.
