Abstract
The invention discloses a secondary flex coil spring suspension device for a 100% low-floor tramcar. The secondary flex coil spring suspension device comprises a framework formed by two side beams and two cross beams together. Two secondary flex coil springs are fixedly arranged on lower installation bases at the two ends of each cross beam. In each cross beam, a vertical damper is arranged beside one secondary flex coil spring, a vertical stopping part is arranged beside the other secondary flex coil spring. A transverse stopping part is fixedly arranged on the inner side of the middle of each side beam, a transverse damper is fixedly arranged on the outer side of one end of each side beam, and the vertical stopping parts, the vertical dampers, the transverse stopping parts and the transverse dampers are all symmetrically arranged about the central point of the framework. The secondary flex coil spring suspension device has the advantages that the secondary flex coil springs can bear vertical load from a tramcar body and improve the operation stability of the tramcar, and meets the requirement that a large turning angle is generated when the tramcar passes through small-curve tracks; the transverse stopping parts and the vertical stopping parts limit the maximum transverse displacement and side rolling displacement of a tramcar body relative to a bogie; the vertical dampers and the transverse dampers are used for improving the vibration damping performance of the tramcar and improving the stability and the smoothness.
Description
Technical field
The present invention relates to light rail train technical field, particularly a kind of is high circle spring suspension gear for two of 100% low floor tramway train.
Background technology
Low floor light rail train is in a kind of extensively use abroad novel, low freight volume Rail Transit System, there are efficient and convenient, energy-conserving and environment-protective, safety and comfort, take the advantages such as path resource is few, low cost, the construction period is short, operation cost is low, be also developed rapidly at home at present.Wherein 100% low floor light rail train better becomes the emphasis of light rail train development with it without platform, upper and lower passenger's convenience, traveling comfort and safety are set.Bogie truck is its important constituent elements, secondary suspension system is the pith of bogie truck composition, the feature of secondary suspension system is: utilize two to be vertical stiffness and the lateral stiffness of high circle spring, actv. has reduced the vibration of train, be that high circle spring two ends add rubber pad two simultaneously, can hinder the vibration damping of making an uproar, adjust the vertical and transverse height of spiral spring, passenger is taken more comfortable, train operation is more steady; It is Vertical Vibration Reduction performance that vertical damper is used for improving vehicle two, and it is lateral vibration absorbing performance that lateral damper is used for improving vehicle two, improves the stationarity that vehicle bend passes through.
At present, domestic 100% low floor tramway train is also in development, and in order to realize low floor, necessary employing is simple and reliable for structure, the secondary suspension system that space hold is few.This system is simpler than traditional secondary suspension system architectures such as air spring suspension, takes up room less, is more suitable for 100% low floor tramway train.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, providing a kind of is high circle spring suspension gear for two of 100% low floor tramway train.
The technical solution used in the present invention is such: a kind of is high circle spring suspension gear for two of 100% low floor tramway train, comprise the framework of two curb girders and two common compositions of crossbeam, described crossbeam two ends are respectively equipped with lower installation seat plate, on lower installation seat plate, being fixed with two two is high circle spring, on every lower installation seat plate, one two is that high circle spring side arranges vertical damper, another root two is that high circle spring side arranges vertical backstop, inner side, described every curb girder middle part is fixedly installed a horizontal backstop, outside, crossbeam one end is fixedly installed lateral damper, described each vertical backstop, vertical damper, laterally backstop and lateral damper all arrange according to framework central point.
As preferably, described two is that high circle spring top is provided with rubber tie plate, and bottom is provided with lower rubber tie plate.By this preferred structure, can effectively reduce two is lateral stiffness value, relaxes from the transverse force excitation between wheel track, improves lateral direction of car operation stability.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows:
1, adopt four two to be the framework both sides that high circle spring is arranged in bogie truck, full side bearing structure, can bear the vertical load from car body on the one hand, can improve on the other hand the running stability of vehicle; Meanwhile, two is that high circle spring is arranged on framework outside, the requirement that produces larger corner when this design can meet vehicle by little curve track;
2, laterally backstop has limited respectively the maximum transversal displacement of the relative bogie truck of car body and has sidewindered displacement with vertical backstop, has avoided, in the time that two are high circle spring inefficacy, can transmitting the vertical force load from car body simultaneously;
3, vertical damper, mainly provides vehicle to sidewinder damping, and that improves vehicle sidewinders stability and running stability;
4, lateral damper is used for improving lateral direction of car cushioning performance, improves the lateral stability of vehicle and the stationarity that bend passes through;
5, integral structure is simple, small and exquisite, realizes 100% low floor created favourable space for tramway train.
