Description
Technical field
The present invention relates to a kind of middle low speed magnetic suspension train running mechanism.
Background technology
The running mechanism in every joint compartment all is identical in the usually middle low-speed maglev train.For the smooth running that guarantees magnetically supported vehicle and smoothly by bend, the running mechanism in every joint compartment can be provided with two fixed-point type running modules that can rotate with car body and cross travel can not take place at most.When running module during more than two, the running module that has more then must be to take place relative to cross travel and the portable running module that rotates with car body.
The main composition of fixed-point type running module is: air bellow is arranged on four ends of suspension frame, slide unit is fixed on two air bellow tops of adjacent running module, connect adjacent running module and support car body, the tractive force that linear motor rotor on the suspension frame and the stator on the track produce is delivered to slide unit by draw bar, slide unit and car body are fixed, and by slide unit tractive force are passed to car body.
Portable running module then its slide unit is not captiveed joint with car body, but is connected with car body by two horizontal linear bearings that are provided with on the slide unit; Tractive force passes to slide unit by the suspension frame by draw bar, drives car body by the linear bearing on the slide unit 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 running mechanism has the following disadvantages: one, because slide unit is arranged on two air bellows between the adjacent suspension frame, a common running module and four slide units, eight air bellows are associated, portable running module also is associated with eight linear bearings.Whole magnetic-levitation train needs a lot of air bellow and linear bearing, complex structure, cost height.Two, two the horizontal linear bearings on the slide unit of portable running module when bearing car body weight, transmitting tractive or braking force, 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, limited length, made the power of linear electric motors less, and the crest clearance of adjacent linear motor rotor is increased in the linear motor rotor of suspension frame middle and lower part, the efficient of linear electric motors reduces, and influences the running velocity of magnetically supported vehicle.
Summary of the invention
Purpose of the present invention just provides the mid-middle low speed magnetic suspension train running mechanism of a kind of air bellow, this running mechanism 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: the middle low speed magnetic suspension train running mechanism that a kind of air bellow is mid-, the running mechanism in every joint compartment comprises that at least one can take place that the portable running module of relative cross travel and two can rotate with car body and fixed-point type running module that cross travel can not take place with car body, movable type or fixed-point type running module include: two draw bars on suspension frame, the suspension frame and air bellow, and its constructional feature is:

Working process of the present invention and principle are:
Tractive force on two fixed-point type modules passes to bolster by the draw bar of both sides, and bolster bears car body weight by center pin, simultaneously tractive force is directly passed to car body effectively, makes the operation of car body high-speed smooth ground.Two draw bars are separately positioned on the front and rear above the suspension frame, two draw bars and bolster constitute zigzag, like this when the suspension frame is crossed the relative car body of bend and is rotated, bolster in the zigzag structure can rotate around center pin, thereby compensate the change in location at the two ends of draw bar effectively, make car body pass through bend smoothly.
Portable running module is delivered to tractive force on the bolster by the suspension frame then by the draw bar between suspension frame and the bolster, by guiding piece tractive force is delivered to draft arm again, drives the car body longitudinal movement by draft arm.Because the center and the car body pin joint of the guiding piece on the bolster, and the trailer coupling of two ends and two draft arm formation zigzags.When vehicle was crossed bend, the guiding piece and the draft arm of zigzag horizontally rotated generation, and allowed car body and bolster and guiding piece point of connection can produce cross travel.Simultaneously, the suspension frame is realized vertical load-bearing by suspension rod, supports car body; Because suspension rod is suspended on the suspension frame, and car body is hinged with suspension rod, thereby can realize that the longitudinal travel that laterally reaches of the two compensates by the swing of suspension rod between car body and the suspension frame.Also be that the point of connection of car body and guiding piece and the point of connection of suspension rod all can produce laterally and the longitudinal travel compensation; When guaranteeing tractive force transmission and load-bearing, can not make car body waltz through bend to the outer constraint of the relative motion plus between suspension frame and car body.
In a word, during the magnetically supported vehicle operation, two fixed-point type running modules can rotate in the junction with car body, and several portable running modules then can rotate in the junction with car body and horizontal relative displacement, thereby can guarantee that magnetically supported vehicle passes through bend steadily, smoothly.
Compared with prior art, the invention has the beneficial effects as follows:
One, cancelled the former slide unit that is secured in the running module end, replace the bolster that is fixed on suspension frame midway location, an air bellow is only installed in the end of bolster, in the whole running mechanism, air bellow quantity has reduced half, simplify the structure and make assembly technology, reduced manufacturing and maintenance cost.
Two, portable running module utilizes the rotation of z font trailer coupling and the swing of suspension rod, realize the cross travel compensation between car body and suspension frame, 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, making maintenance cost and obviously reduce with cheap, easy-to-install zigzag trailer coupling and suspension rod, and assembling with keep in repair easy.
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 not located in the end 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.
