In figure, each parts label is as follows: framework composition 1, vertical hydraulic damper 2, spring guide pillar 3, steel coil spring 4, rubber stack positioner 5, large fluted nut 6, buffer rubber gasket 7, lifting block 8, little fluted nut 9, axle box 10 (wherein: through hole 10a, the vertical gear of arc 10b, infrared journal temperature detection hole 10c), positioning step 11, spring cotter 12, straight pin 13, detent 14, rigidity packing ring 15.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Railway goods train bogie one is as shown in Figure 1 hanging and locating device of axle box, comprises axle box 10, is arranged on axle box 10 tops and framework and forms vertical hydraulic damper 2 between 1 bogie side frame, be arranged on above axle box 10 both sides spring bearing platforms and framework forms spring guide pillar 3, steel coil spring 4 and the rubber stack positioner 5 between 1 bottom and is arranged on the lifting block 8 below axle box 10 both sides spring bearing platforms.What the vertical hydraulic damper 2 in the present embodiment adopted is two-stage or multistage change damping shock absorber.
Shown in Fig. 2, upper transverse plane and the framework of spring guide pillar 3 forms 1 bottom and is fixedly connected with, insert in rubber stack positioner 5 inner rings in the stage casing of spring guide pillar 3, rubber stack positioner 5 bottom surfaces are located in above the spring bearing platform of axle box 10, rubber stack positioner 5 bottoms, outer ring are set with buffer rubber gasket 7, buffer rubber gasket 7 is provided with rigidity packing ring 15 above, and steel coil spring 4 is arranged between rigidity packing ring and the upper transverse plane of spring guide pillar 3.
The lower end of spring guide pillar 3 is passed successively the through hole 10a on the spring bearing platform of axle box 10 and is lifted by crane the centre hole on block 8, and is provided with first order screw thread, positioning step 11 and second stage screw thread from top to bottom; On first order screw thread, be equipped with rubber stack positioner 5 bottoms and be tight against the large fluted nut 6 coordinating, lifting block is nested with between positioning step 11 and second stage screw thread, is equipped with and lifting block 8 can be locked to the little fluted nut 9 of positioning step 11 bottom surfaces on the screw thread of the second stage.
And steel coil spring 4 gets loose separatedly with the upper transverse plane of spring guide pillar 3 when empty wagons, steel coil spring 4 is when loaded vehicle and the upper transverse plane butt pressure-bearing of spring guide pillar 3, and the holder when lifting of lifting block 8 is connected on below the spring bearing platform of axle box 10.
Principle of work of the present invention is as follows: rubber stack positioner 5 links into an integrated entity by spring guide pillar 3 and large fluted nut 6, transmits vertical, the vertical and horizontal load of vehicle between framework composition 1 and axle box 10.During due to empty wagons, load is less, steel coil spring 4 tops not yet touch transverse plane on spring guide pillar 3, now only there are rubber stack positioner 5 carrying pressurizeds, during loaded vehicle, rubber stack positioner 5 continues to bottom offset, and combines carrying pressurized with steel coil spring 4, guaranteed the requirement of lorry two stage stiffness under empty and load operating mode, realize the elasticity positioning function of single stage suspension, effectively reduced the wheel-rail impact power of vehicle, improved vehicle dynamics performance;
Simultaneously, connection by spring guide pillar 3, lifting block 8, little fluted nut 9 and axle box 10 is spacing, framework is formed to 1 and be combined into integral body with the reciprocity unsprung weight of wheel, when lifting, holder is connected on the through hole 10a bottom of the both sides spring bearing platform of axle box 10, can realize integral lifting, the transhipment of bogie truck, simple in structure, compact, reliable, optimized assembling space, eliminated the hidden danger of the axle box suspension rod handling slippage that adopts T-shape structure;
Therefore, the two-stage thread connecting mode that spring guide pillar 3 arranges is the integrated design, simple in structure, compact, dependable performance, guarantee that positioning performance is stable, be conducive to meet requirement vertical, that vertical and horizontal have different locating stiffnesses, can alleviate unsprung weight, reduce wheel track dynamic deformation from motion, reduce wheel-rail wear.
In addition, again as shown in Figure 2, the centre hole both sides of lifting block 8 are provided with detent 14, and the lower end of spring guide pillar 3 is provided with cylinder pin hole corresponding to detent 14 places, in cylinder pin hole, be provided with the straight pin 13 matching with detent 14, prevent from lifting by crane block 8 and rotate; The lower end of spring guide pillar 3 is respectively arranged with cotter-pin hold corresponding to the notch place of large fluted nut 6 and little fluted nut 9, in cotter-pin hold, be provided with the spring cotter 12 matching with the notch of large fluted nut 6 and little fluted nut 9, prevent that large fluted nut 6 and little fluted nut 9 from rotating, getting loose.
Shown in Fig. 3, the through hole 10a on the spring bearing platform of axle box 10 is rounded or oval, the setting of this through hole 10a, can prevent rubber stack positioner 5 and spring guide pillar 3 under empty and load operating mode because each interferes to displacement deformation; In addition, the periphery of through hole 10a is provided with the vertical gear of the arc 10b coordinating with rubber stack positioner 5 location, outer ring, and play and rotation occur in the outer ring that the vertical gear of this arc 10b can limit rubber stack positioner 5, guarantee its positioning action; Simultaneously, the saddle basifacial of axle box 10 is provided with infrared journal temperature detection hole 10c, having solved existing roller bearing adapter stabilizer bar one is that axle box can not adopt the deficiency of infrared temperature when circuit moves, can detect in real time the train bearing temperature under running state, avoid visiting because leaking the hot box trouble causing, guarantee safety of railway traffic.
