Description
Technical field
The present invention relates to a kind of parts of running module of middle low speed magnetic suspension train.
Background technology
In existing in the low-speed maglev train running gear, for the smooth running that guarantees magnetically supported vehicle especially smoothly by bend, in running gear, must be provided with can with the running module of cross-car displacement.This kind running module comprises the air bellow that is provided with on four jiaos on the suspension frame, and two air bellows of adjacent suspension frame support a Mobile Slide, and Mobile Slide is provided with two horizontal linear bearings.Car body is supported on the linear bearing.Its trailer coupling mainly is made up of draw bar, Mobile Slide and linear bearing thereof, passes to Mobile Slide by the suspension frame by draw bar, drives car body by linear bearing on the Mobile Slide again and vertically advances.Like this can normal delivery tractive force longitudinally, simultaneously when bend, running module is by producing horizontal moving between horizontal linear bearing on the Mobile Slide and the car body, thereby makes car body can waltz through bend.But existing this module has the following disadvantages: one, since Mobile Slide be arranged on two air bellows between the adjacent suspension frame, a common running module relates to four Mobile Slides, eight air bellows, eight linear bearings, whole magnetic-levitation train needs a lot of air bellow and linear bearing, complex structure, the cost height.Two, two the horizontal linear bearings on each Mobile Slide when bearing car body weight, also will guarantee side travel smoothly.All very high to the accuracy requirement of linear bearing itself and installation like this, make that the assembling of magnetically supported vehicle running mechanism and maintenance difficulties are big, installation and maintenance cost height.Three, two air bellows under slide unit and the slide unit are as load-supporting part, be installed in four ends of running module, make the end mounted component of running module a lot, the base of middle and lower part, end is roomy, has limited the length at the linear motor stator electric of suspension frame middle and lower part, and the power of linear electric motors is descended, and the crest clearance of adjacent linear motor rotor is increased, the efficient of linear electric motors reduces, and wastes energy, and has also limited the running velocity of magnetically supported vehicle.
Summary of the invention
Purpose of the present invention just provides a kind of movable type, the mid-middle low-speed maglev train running module trailer coupling of air bellow, adopts the running module of this trailer coupling simple in structure, and productive costs is low, installs easy to manufacture; Linear electric motors power is big, the efficient height, and the magnetically supported vehicle running velocity is fast.
The present invention solves its goal of the invention, the technical scheme that is adopted is: a kind of movable type, the mid-middle low-speed maglev train running module trailer coupling of air bellow, comprise: two draw bars on suspension frame, the suspension frame and air bellow, its constructional feature is: the midway location of suspension frame laterally is provided with bolster, and the air bellow of the both ends of bolster below it is fixedly supported on the suspension frame; The center of bolster is connected with guiding piece by connecting pin, and the two ends of guiding piece are hinged with draft arm respectively, and the other end and the car body of draft arm are hinged, and two draft arms lay respectively at the place ahead, the rear of guiding piece; The two ends of bolster also with the suspension frame on two draw bars hinged.
Principle of work of the present invention is: by the draw bar between suspension frame and the bolster, tractive force is delivered on the bolster by the suspension frame, by guiding piece tractive force is delivered to draft arm again, drive the car body longitudinal movement by draft arm.Since the center and the bolster pin joint of the guiding piece on the bolster, the trailer coupling of guiding piece and two draft arm formation zigzags.When vehicle is crossed bend, the guiding piece of zigzag and draft arm generation is horizontally rotated, and make cross travel between car body and bolster, also promptly when guaranteeing that tractive force transmits, can not make car body waltz through bend to the outer constraint of the relative motion plus between suspension frame and car body.
Compared with prior art, the invention has the beneficial effects as follows:
One, cancels the former Mobile Slide that is secured in the running module end, replaced the bolster that is fixed on suspension frame midway location.Utilize the rotation of zigzag trailer coupling, realize the horizontal of car body and bolster and rotation displacement compensation, rather than the slip of the horizontal linear bearing on the slide unit realizes.Guaranteeing that magnetically supported vehicle can be smoothly by under the prerequisite of curve track like this, replacing the linear bearing of original costliness, make maintenance cost and obviously reduce, and assembling is being easy with maintenance with cheap, easy-to-install zigzag trailer coupling.
Two, an air bellow is only installed in the end of bolster, and quantity has reduced half, also simplifies the structure and makes assembly technology, has reduced manufacturing and maintenance cost.
Three, the air bellow of bolster and end thereof is positioned at above the suspension frame, does not have the midway location of other parts, and installing space is big, and assembling and easy to maintenance is installed, and has further reduced installation and maintenance cost;
Four, the air bellow of bolster and its underpart is arranged in the middle part of suspension frame, the parts of four end positions of suspension frame are significantly reduced, the end takes up room little, the linear motor rotor length of middle and lower part, suspension frame both sides can increase, and increases the power of linear electric motors, simultaneously, spacing between the linear motor rotor of adjacent suspension frame reduces, the end effect of linear electric motors weakens, and efficient improves, the running velocity height of magnetically supported vehicle.
The present invention is described in further detail below in conjunction with accompanying drawing and concrete embodiment.

The specific embodiment
Embodiment
Fig. 1,2,3 illustrates, a kind of specific embodiment of the present invention is: a kind of movable type, the mid-middle low-speed maglev train running module trailer coupling of air bellow, comprise: two draw bars 2 on suspension frame 1, the suspension frame 1 and air bellow 3, the midway location of suspension frame 1 laterally is provided with bolster 4, and the air bellow 3 of the both ends of bolster 4 below it is fixedly supported on suspension frame 1; The center of bolster 4 is connected with guiding piece 7 by connecting pin 6, and the two ends of guiding piece 7 are hinged with draft arm 8 respectively, and the other end and the car body of draft arm 8 are hinged, and two draft arms 8 lay respectively at the place ahead, the rear of guiding piece 7; The two ends of bolster 4 also with suspension frame 1 on two draw bars 2 hinged.
Obviously, the present invention in the specific implementation, draft arm 8 can also be installed on car body.That is: after the mode of draft arm 8 by pin joint was installed in the car body bottom, draft arm 8 carried out pin joint with rolling disc again.
The various support mechanisms that the running module that adopts trailer coupling of the present invention then can be led on the bolster 4 to the load-bearing of car body are realized.As: the outside, the two ends suspention at bolster 4 has suspension rod 9, and the other end of suspension rod 9 and the pipe link of car body are hinged.Suspension frame 1 is realized vertical load-bearing by suspension rod 9 floatedly, supports car body.Simultaneously, owing to suspension rod 9 is suspended on the suspension frame 1, and car body is hinged by pipe link and suspension rod 9, thereby can pass through the swing of suspension rod 9 between car body and the suspension frame, and realizes that the longitudinal travel that laterally reaches of the two compensates.
