Description
Technical field
The utility model 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 the 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 take place can be set at most.When running gear during more than two, the running gear that has more must guarantee with car body horizontal movement to take place, and could guarantee that 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 Z font drawing pull bar, and the longitudinal traction power of vehicle is provided.First kind of situation, the two ends of suspension frame longeron respectively adopt a slide unit above air bellow to link to each other with car body.Single suspension frame 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 frame middle and lower part, made that the length of available linear motor rotor is shorter, can't give full play to the towability of linear electric motors, influence the service efficiency of linear electric motors, reduced the floating overall towability of car of magnetic.Second kind of 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.Though this structure has been saved the space on the longeron, has reserved the space to linear electric motors, it is bigger that the suspension frame is installed the space that needs, and floor height has raise.
The utility model content
The purpose of this utility model provides a kind of middle low-speed maglev train traveling equipment, and this equipment can solve the problem that the end installing component is more and floor compartment raises of running module effectively.This traveling equipment has simple in structure, and productive costs is low, installs easy to manufacturely, can increase advantages such as linear electric motors power.
The purpose of this utility model is achieved through the following technical solutions: the traveling equipment of low speed magnetic floating vehicle in a kind of, comprise suspension frame, air bellow and slide unit, be provided with slide unit in the middle of its suspension frame, slide unit links to each other with air bellow by bolt, pedestal on the lower end of air bellow and the suspension frame is affixed, the same side of slide unit and suspension frame 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 frame, has the lateral traction pull bar to link to each other between left and right two slide units.
The working process of the utility model device and principle:
The compartment is connected with the suspension frame by slide unit, the weight that slide unit bears car body by left and right carriage saddle boss, and finally the air bellow that is connected with carriage saddle by the left and right sides passes to the suspension frame, 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 laterally with car body and move, and makes car body smoothly by the curve bend.
Compared with prior art, the beneficial effects of the utility model are:
One, cancelled the former slide rest device that is secured in the running module end, replace the slide rest device that is fixed on suspension frame 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 frame, can guarantee that like this vehicle can pass through curve track smoothly, can replace the structure of original complexity again, 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 laterally moving between car body and the suspension frame, realize the cross travel compensation between car body and the suspension frame.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail.

The specific embodiment
Embodiment
Fig. 1-3 illustrates, and a kind of embodiment of the present utility model is: the traveling equipment of low speed magnetic floating vehicle in a kind of comprises suspension frame 4, air bellow 3 and slide unit 2.Be provided with slide unit 2 in the middle of the suspension frame 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 frame 4 is affixed, the same side of slide unit 2 and suspension frame 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 frame 4, has lateral traction pull bar 5 to link to each other between left and right two slide units 2.
4 on each slide unit 2 and suspension frame also have longitudinal tie 1 to transmit longitudinal force.Slide unit 2 on the suspension frame 4 is middle, has enlarged the space of suspension frame top.And replaced original bolster, the transversal dynamic performance when having improved curve negotiating with slide unit 2.
Compare running mechanism of the present utility model 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 part simultaneously, reduced the probability that breaks down, but actv. improves the work efficiency of running mechanism.Manufacturing process is simplified, improved the structure of end traveling equipment, thereby greatly facilitated running mechanism processing and installation, installing for other equipment provides enough spaces, improve the transversal dynamic performance of the floating car of magnetic simultaneously, when crossing bend, reduced the lateral excursion in compartment.
