Description
Technical field
The invention belongs to the magnetic-levitation train technical field, particularly middle low-speed maglev train running gear.
Background technology
Usually in the magnetic-levitation train in order to guarantee that magnetic-levitation train smoothly by curve bend, arranges running gear below every joint compartment, two fixed-point type running modules that rotate with car body and cross travel can not occur can be set at most.When running gear during more than two, the running gear that has more must guarantee with car body transverse shifting to occur, and the guarantee vehicle passes through curve smoothly.And in existing technology, the traction electric machine of magnetic-levitation train all is that linear electric motors drive, and is subjected to the restriction of installing space, and the linear electric motors driving power is less, can't reach designing requirement.
Maglev vehicle running mechanism in the past generally has two kinds of structures: respectively arrange a slide unit in the end of two side girders, or at the single bolster of center arrangement.Longitudinal towing mechanism at vehicle adopts the Z-shaped drawing pull bar, and the longitudinal traction power of vehicle is provided.The first situation, the two ends of longitudinal beam for suspension frame respectively adopt a slide unit above air bellow to link to each other with car body.Single suspension rack has 4 slide units, air bellow under the bolster is as load-supporting part, be installed in four ends of module out of shape, make the end installing component of running module more, limit the utilization in space, suspension rack middle and lower part, so that the length of available linear motor rotor is shorter, can't give full play to the towability of linear electric motors, affect the service efficiency of linear electric motors, reduced the floating overall towability of car of magnetic.The second situation arranges respectively in the middle part of two side girders to connect bolster at two air bellows by two air bellows that bolster links to each other with car body.Although this structure has been saved the space on the longeron, has reserved the space to linear electric motors, it is larger that suspension rack is installed the space that needs, and floor height has raise.
Summary of the invention
The purpose of this invention is to provide a kind of middle low-speed maglev train running gear, this device can solve the problem that the end installing component is more and floor compartment raises of running module effectively.This running gear has simple in structure, and productive costs is low, installs easy to manufacturely, can increase the advantages such as linear electric motors power.
The objective of the invention is to be achieved through the following technical solutions: a kind of running gear of middle Low-speed maglev vehicle, comprise suspension rack, air bellow and slide unit, be provided with slide unit in the middle of its suspension rack, slide unit links to each other with air bellow by bolt, lower end and the pedestal on the suspension rack of air bellow are affixed, the same side of slide unit and suspension rack is equipped with the longitudinal tie seat, longitudinal tie one end links to each other with the longitudinal tie seat of slide unit, the other end is connected with the longitudinal tie seat of suspension rack, has the lateral traction pull bar to link to each other between left and right two slide units.
The working process of apparatus of the present invention and principle:
The compartment is connected with suspension rack by slide unit, the weight that slide unit bears car body by left and right carriage saddle boss, and the air bellow that finally is connected with carriage saddle by the left and right sides passes to suspension rack, forms portable running mechanism.
The compartment is connected with portable running mechanism by slide unit, and vehicle is by curve the time, and portable slide rest device can produce transverse shifting with car body, so that car body passes through curve bend smoothly.
Compared with prior art, the invention has the beneficial effects as follows:
One, cancelled the former slide rest device that is secured in the running module end, replace the slide rest device that is fixed on the suspension rack intermediate arrangement, an air bellow is only installed in the slide unit end, in the whole running mechanism, air bellow quantity has reduced half, simplify the structure and manufacturing process, reduced manufacturing and maintenance cost.
Two, the mid-slide unit design of adopting air bellow to cooperate has replaced bolster and end slide unit structure, realized flexibly connecting between car body and the suspension rack, can guarantee that like this vehicle can pass through curve track smoothly, can replace again the structure of original complexity, reduce manufacturing cost.
Adopt mid-slide unit to replace four jiaos of slide units and bolster structure, structure is more simple, and it is comparatively convenient to install.Obtain more space to lengthen the length of linear motor rotor, increased linear electric motors power.Realize simultaneously transverse shifting between car body and the suspension rack, realize the cross travel compensation between car body and the suspension rack.
The present invention is described in further detail below in conjunction with accompanying drawing and concrete embodiment.

The specific embodiment
Embodiment
Fig. 1-3 illustrates, and one embodiment of the present invention are: a kind of running gear of middle Low-speed maglev vehicle comprises suspension rack 4, air bellow 3 and slide unit 2.Be provided with slide unit 2 in the middle of the suspension rack 4, slide unit 2 links to each other with air bellow 3 by bolt, pedestal on the lower end of air bellow 3 and the suspension rack 4 is affixed, the same side of slide unit 2 and suspension rack 4 is equipped with the longitudinal tie seat, longitudinal tie 1 one ends link to each other with the longitudinal tie seat of slide unit 2, the other end is connected with the longitudinal tie seat of suspension rack 4, has lateral traction pull bar 5 to link to each other between left and right two slide units 2.
4 of each slide unit 2 and suspension racks also have longitudinal tie 1 to transmit longitudinal force.Slide unit 2 on the suspension rack 4 is middle, has enlarged the space of suspension rack top.And replaced original bolster, the transversal dynamic performance when having improved curve negotiating with slide unit 2.
Compare running mechanism of the present invention with former end running mechanism and replaced four original slide units in both sides with two middle slide units.Slide unit directly links to each other with air bellow by bolt, has replaced the bolster of original use.Reduced the lateral direction of car vibrations, simplified simultaneously part, reduced the probability that breaks down, but actv. improves the work efficiency of running mechanism.Manufacturing process is simplified, improved the structure of end running gear, thereby greatly facilitated running mechanism processing and installation, installing for other equipment provides enough spaces, improve simultaneously the transversal dynamic performance of the floating car of magnetic, when crossing bend, reduced the lateral excursion in compartment.
