Abstract
The utility model discloses a secondary flex coil spring suspension device for a 100% low floor tramcar. The secondary flex coil spring suspension device comprises a framework consisting of two side beams and two transverse beams, two secondary flex coil springs are fixedly arranged on lower mounting seat plates at two ends of each transverse beam, a vertical damper is arranged beside one secondary flex coil spring, a vertical stopper is arranged beside the other secondary flex coil spring, a transverse stopper 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 stoppers, the vertical dampers, the transverse stoppers and the transverse dampers are symmetrically arranged around the center 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 car body and improve running stability of the car, the car can generate a large rotating angle when passing a small curve rail, the maximum transversal displacement and side rolling displacement of the car body relative to a bogie are limited by the transverse stoppers and the vertical stoppers respectively, the vertical dampers and the transverse dampers are used for improving the damping performance of the car, and stability and smoothness are improved.
Description
Technical field
The utility model relates to light rail train technical field, and 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.
Utility model content
Goal of the invention of the present utility model 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 adopted in the utility model 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 beneficial effects of the utility model are:
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.
Brief description of the drawings
