A suspension frame is provided with a longitudinal supporting beam fixed in the middle of a train body of the magnetic-levitation train; one end of each suspension guide module is sleeved on the longitudinal supporting beam through a bearing, and the suspension guide modules are arranged on both sides of the longitudinal supporting beam in pairs in a bilateral symmetry manner; and the suspension guide module comprises a transverse support and an electromagnet arranged at one end of the support, and an air spring connected with the train body is arranged on the suspension guide module. By adopting the structure, the suspension controller for each module can serve as an independent system, so that the design difficulty of the controller is lowered, the stability of the suspension system is enhanced, the dynamic characteristics of running of the magnetic-levitation train are improved, the requirements to the design and manufacturing accuracy of the functional surface of the guide rail are further lowered, and the total cost is reduced.
Description
Technical field
The utility model relates to magnetic-levitation train, especially often leads (EMS type) magnetic-levitation train manufacturing field of equipment.
Background technology
The floating train (EMS type) of normal magnetic conduction is to utilize conventional DC electromagnet electromagnetic attraction that train is floated, and drives with the linear electric motors no touch, is divided into two kinds of frame modes of high-speed type and low speed type.The low speed type is representative with the HSST of Japan, and high-speed type is representative with the TR series of Germany.
Low speed EMS magnetic-levitation train is suspended jointly by a plurality of vertically end to end magnetic bogie trucks, and each bogie truck as shown in Figure 1.All have independently and suspend, lead and drive function.Be connected by air bellow 1 between bogie truck and the car body.Each bogie truck by two relatively independent, sidewinder beam 2 bonded assembly modules 3 and constitute by anti-.Owing to sidewinder beam 2 and be connected by anti-between the module of bogie truck both sides with hanger 5, be connected by air bellow with car body, can think decoupling zero on physical construction between each module.But module is approximately rigid body, and motion in vertical direction is a two degree freedom system.Two of the inside modules ends (electromagnet 4) that suspend connect by rigid body, cause existing strong machinery to intercouple between the state of kinematic motion at two ends.
Each suspension bogie of high speed EMS magnetic-levitation train as shown in Figure 2, comprise two groups of C type suspension arch, by levitating electromagnet 15, guiding electromagnet module 14 and the spring chain structure that suspension framework 13 overlap joints are constituted, utilize a longeron 12 that two adjacent suspension frameworks 13 connections are formed.Two adjacent suspension frameworks transmit load mutually by the levitating electromagnet linkwork, when one of them part levitating electromagnet et out of order, can be born the load of suspension framework by adjacent part levitating electromagnet.For load and electric current to levitating electromagnet average distribution, by to the filling of air bellow 11, load that suspension framework 13 is regulated in exhaust.Therefore, respectively the suspending a little of each suspension bogie, and all have mechanical couplings between each suspension bogie.
Because magnetic suspension train adopts multiple spot Suspension Control technology, and this because the coupling that the physical construction characteristic causes must cause intercoupling between each suspension controller, influences the suspension system stability of car load.Processing method commonly used is with the external disturbance of this coupling as system, is suppressed by the robustness that improves system, and the design difficulty of controller strengthens.And suspension, guiding and drive system proposed higher design and accuracy of manufacture requirement to three function faces of guide rail, makes setting accuracy and require basically all to have increased manufacturing, the installation and maintenance cost of guide rail and beam in 1 mm.
Summary of the invention
Deficiency in view of existing magnetic floating train suspending system, the purpose of this utility model provides a kind of new magnetic floating train suspending block construction, make it to overcome the above shortcoming of prior art, start with from physical construction and to improve coupling condition, thereby reduce the design difficulty of controller, improve the stability of suspension system, improve the dynamic characteristics of magnetic-levitation train operation.
The purpose of this utility model realizes by following means.
A kind of magnetic floating train suspending block construction, mainly constitute by suspension framework and the air bellow etc. that places the suspension and the guiding electromagnet of suspension framework bottom and be arranged on the suspension frame ends, it is characterized in that the suspension framework has a longitudinal supporting beam that is fixed on the car body middle part of magnetic-levitation train; One end of suspension oriented module is connected on the support beam by bearing carrier ring, and left-right symmetric is arranged in pairs in longitudinal supporting beam both sides; Described suspension oriented module is made of horizontal support and the electromagnet that is arranged on support one end, and it is provided with and is used for the air bellow that connects with car body.
Adopt structure of the present utility model, each electromagnet and horizontal support constitute the oriented module that independently suspends, be connected by rolling bearing between each module and the longitudinal supporting beam, can freely rotate within the specific limits, connect by air bellow respectively between each module and the car body around support beam.Therefore, the part load of each module independent bearing vehicle, the mode of operation of its mode of operation and other modules is irrelevant, has realized full decoupled between each module.Therefore the suspension controller of each module can be used as the autonomous system design, has reduced the design difficulty of controller, improves the stability of suspension system, improves the dynamic characteristics of magnetic-levitation train operation.The raising of control quality also can reduce the design and the accuracy of manufacture requirement of guide rail function face.And physical construction also can modularization, is convenient to production and processing, cost-cutting.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In Fig. 3: the suspension framework has a longitudinal supporting beam 111 that is fixed on the car body middle part of magnetic-levitation train.One end of suspension oriented module is socketed on the support beam 111 by bearing 113, and suspension oriented module left-right symmetric is arranged in pairs in longitudinal supporting beam both sides.The suspension oriented module is made of horizontal support 112 and the electromagnet 115 that is arranged on horizontal support one end, and the suspension oriented module is provided with and is used for the air bellow 114 that connects with car body.
In a bogie truck unit, longitudinal supporting beam 111 is socketed with at least two pairs of suspension oriented modules.Adopting three pairs of suspension oriented modules of socket in the present embodiment is example.
Above what state only is the preferred implementation of the utility model method, should be pointed out that under the prerequisite that does not break away from the utility model method essence, can make some changes and should be included in the protection domain of the present utility model in reality is implemented.
