For achieving the above object, the technical solution of the utility model is:
A kind of rail vehicle truck secondary suspension device, a plurality of steel coil springs are set between car body and bogie truck, two ends up and down at each described steel coil spring are provided with upper padding plate and lower bolster, described upper padding plate is captiveed joint with car body, described lower bolster is captiveed joint with bogie truck, described upper padding plate and lower bolster are formed by two-layered steel plates and middle rubber layer, have the stopper protrusion that the inner ring to described steel coil spring stretches out on described upper padding plate and lower bolster.
Further, described stopper protrusion is an annular.
Further, lower floor's steel plate in described stopper protrusion and the described upper padding plate and the upper strata steel plate in the described lower bolster are one-body molded.
Further, the sulfuration of described rubber layer and described two-layered steel plates is structure as a whole.
Further, the height of described stopper protrusion is that 1 of described steel coil spring free height is enclosed to 2 circles.
Further, the height of described stopper protrusion is that 1.5 of described steel coil spring free height is enclosed to 2 circles.
Further, the thickness of described rubber layer is 30 ~ 40mm.
Further, the center of described upper padding plate and described lower bolster has and is used for fixing the opening that is connected usefulness.
Further, the diameter of described opening is 100 ~ 120mm.
Further, be bolted to connection respectively between the upper strata steel plate in the described upper padding plate and the lower floor's steel plate in the described lower bolster and described car body and the bogie truck.
Content to sum up, rail vehicle truck secondary suspension device described in the utility model, used the steel coil spring, load-carrying capacity improves, and when vehicle need pass through little curve, promptly when spring produces big displacement, stopper protrusion by two inside annulars plays backstop action preferably, blocks the spring bar of spring end, effectively avoid the spring unstability, and then guarantee that vehicle passes through curve smoothly.
Description of drawings
Fig. 1 is the utility model package assembly scheme drawing;
Fig. 2 is the utility model suspension gear structural representation.
As depicted in figs. 1 and 2, car body 1, bogie truck 2, steel coil spring 3, upper padding plate 4, lower bolster 5, upper strata steel plate 6, lower floor's steel plate 7, rubber layer 8, upper strata steel plate 9, lower floor's steel plate 10, rubber layer 11, last stopper protrusion 12, following stopper protrusion 13, upper shed 14, under shed 15, last bolt 16, following bolt 17.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As depicted in figs. 1 and 2, rail vehicle truck secondary suspension device described in the utility model, be arranged between car body 1 and the bogie truck 2, the secondary suspension device is used to reduce the vibration that locomotive is produced owing to the impact from rail, improving the reliability of equipment in the car body and the stationarity of locomotive operation, is the elastic connecting device between car body 1 and the bogie truck 2.
The secondary suspension device comprises a plurality of steel coil springs 3 that are arranged between car body 1 and the bogie truck 2, adopts steel coil spring 3 can significantly improve the load-carrying capacity of this secondary suspension device.Be provided with upper padding plate 4 and lower bolster 5 at the two ends up and down of each steel coil spring 3, upper padding plate 4 is captiveed joint with car body 1, and lower bolster 5 is captiveed joint with bogie truck 2.
Upper padding plate 4 is made up of upper strata steel plate 6, lower floor's steel plate 7 and middle rubber layer 8, and rubber layer 8 is structure as a whole with upper strata steel plate 6 and 7 sulfurations of lower floor's steel plate.Lower bolster 5 is made up of upper strata steel plate 9, lower floor's steel plate 10 and rubber layer 11, and rubber layer 11 is structure as a whole with upper strata steel plate 9 and 10 sulfurations of lower floor's steel plate.The setting of rubber layer 8 and rubber layer 11 is to have less lateral stiffness when making 3 work of steel coil spring, improves the state of stress of steel coil spring 3 simultaneously.Rubber layer 8 and rubber layer 11 thickness be 30 ~ 40mm, wherein preferred 34mm.
The center of upper padding plate 4 has and is used for fixing the upper shed 14 that connects usefulness, and the center of lower bolster 5 has and is used for fixing the under shed 15 that connects usefulness, and the diameter of upper shed 14 and under shed 15 is 100 ~ 120mm, wherein preferred 110mm.Captive joint with following bolt 17 by last bolt 16 respectively between upper strata steel plate 6 in the upper padding plate 4 and the lower floor's steel plate 10 in the lower bolster 5 and car body 1 and the bogie truck 2, last bolt 16 and 17 whiles of play bolt can also play a part the whole spring installation of handling.
Vehicle is during by little curve, car body 1 and bogie truck 2 produce very big angle of revolution, cause steel coil spring 3 to produce big horizontal displacement, when steel coil spring 3 produces big displacement, because last stopper protrusion 12 and following stopper protrusion 13 are separately fixed on car body 1 and the bogie truck 2 by upper padding plate 4 and lower bolster 5, and go up the inside that stopper protrusion 12 and following stopper protrusion 13 also stretch to steel coil spring 3, then can play the effect of actv. stop, block the spring bar of steel coil spring 3 ends, effectively prevent steel coil spring 3 unstabilitys, guarantee the smooth curve of vehicle, and then guarantee the stationarity of vehicle operating, it has increased substantially the little curving performance of vehicle by succinct structure.
The height of last stopper protrusion 12 and following stopper protrusion 13 is difficult for oversize or too short, the too short effect that does not have backstop, the oversize lateral stiffness of whole steel coil spring 3 that then can make is excessive, and then influence vehicle performance, through lot of experiment validation, in the present embodiment, the height of last stopper protrusion 12 and following stopper protrusion 13 is preferably 1 circle of steel coil spring 3 free heights to 2 circles, wherein, optimum value adopts the 1.5-2 circle.
As mentioned above, given in conjunction with the accompanying drawings scheme content can derive the similar techniques scheme.In every case be the content that does not break away from technical solutions of the utility model, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical solutions of the utility model according to technical spirit of the present utility model.
