Abstract
The utility model discloses a secondary sandglass spring suspension device for a 100% low floor tramcar. The secondary sandglass spring suspension device comprises a framework consisting of two side beams and two transverse beams, fixing seats are arranged at two ends of each of the two transverse beams, two sandglass springs are fixedly arranged on the fixing seats, a vertical stopper is arranged beside one sandglass spring, a vertical damper is arranged beside the other sandglass spring, transverse stoppers are correspondingly arranged on the inner sides of the middles of the two side beams of the framework, a transverse damper is 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 distributed around the center of the framework. The secondary sandglass spring suspension device has the advantages that the sandglass springs effectively reduce vibration of a train and can also resist noise, so that passengers feel more comfortable when taking the train, the train runs more smoothly, the vertical dampers and the transverse dampers are used for improving secondary vertical and transverse damping performances of the tramcar respectively, smoothness of the tramcar passing a curve is improved, and the secondary sandglass spring suspension device is simple in structure, smaller in occupied space and suitable for the 100% low floor tramcar.
Description
Technical field
The utility model relates to light rail train technical field, and particularly a kind of is hourglass 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 the important constituent elements of 100% low floor light rail train, and secondary suspension system is the pith of bogie truck composition.
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.
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 hourglass 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 hourglass spring suspension gear for two of 100% low floor tramway train, comprise two curb girders and two common frameworks that form of crossbeam, the two ends of two crossbeams are provided with permanent seat, on described permanent seat, be fixedly installed two hourglass springs, a hourglass spring side arranges vertical backstop, another root hourglass spring side arranges vertical damper, two inner side, curb girder middle part correspondences of described framework arrange horizontal backstop, curb girder one end arranged outside lateral damper, each vertical backstop, vertical damper, horizontal backstop and lateral damper distribute according to framework central point.
As preferably, before described hourglass spring bottom is connected with permanent seat, a backing plate is first set.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, utilize vertical stiffness and the lateral stiffness of hourglass spring, bear vertical force and transverse force load from car body, effectively reduced the vibration of train;
2, hourglass spring, from as elastomeric material, can hinder the vibration damping of making an uproar, and passenger is taken more comfortable, and train operation is more steady;
3, to be used for improving vehicle two be Vertical Vibration Reduction performance to vertical damper; Lateral damper, be lateral vibration absorbing performance for improving vehicle two, improve the stationarity that vehicle bend passes through;
4, laterally backstop has limited respectively the maximum transversal displacement of the relative bogie truck of car body and has sidewindered displacement with vertical backstop;
5, take up room littlely than traditional secondary suspension systems such as air spring suspension, be more suitable for 100% low floor tramway train;
6, have simple in structure, dependable performance, cost of manufacture low, adapt to empty and load requirement preferably, easily by compared with remarkable advantages such as small curve radius.
Brief description of the drawings
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Mark in figure: 1 is hourglass spring, 2 is vertical backstop, and 3 is vertical damper, and 4 is horizontal backstop, and 5 is lateral damper, and 6 is framework, and 7 is backing plate, and 8 is permanent seat.
