Description
Technical field
The utility model belongs to normal conducting electromagnetic levitation type levitation train running mechanism technical field, more particularly to middle low speed
Maglev vehicle suspension rack structure.
Background technology
It is significant poor to exist between normal conducting electromagnetic levitation type (EMS) maglev vehicle system and common rail vehicle system
Not, the bogie relative to conventional rails vehicle is mainly reflected in, maglev vehicle supports car body using suspension rack.Suspension rack does not have
Wheel makes vehicle suspension and walking to structure using levitating electromagnet and the suction and repulsive force of interorbital thereon.It
Advantage is, with the substitution Wheel Rail Contact that suspends, to greatly reduce the abrasion in vehicle operation, reduce the operation of vehicle into
This.Noise is very small in operation for magnetic-levitation train simultaneously, when town and country are run with very big advantage.
Existing medium-and low-speed maglev vehicle suspension frame torr arm configuration is divided into two kinds.One kind employs integral structure structure,
A flange is respectively welded in longeron two ends, and trailing arm is connected by flange with longeron, the company of being bolted between flange and trailing arm
Connect, steady pin is also fitted between flange and trailing arm.This integral type support arm structure is primarily present following deficiency：Flange is with indulging
Beam needs welding, the bad control of malformation caused by welding；Flange is bolted with trailing arm, is difficult to control trailing arm with indulging
The position relationship of beam, and structural stability is difficult to ensure that；Flange only three sides open up bolt hole, do not form envelope between flange and trailing arm
Connection is closed, and the corresponding bolt hole of trailing arm opens up the complexity that position increases installation；Linear electric motors installation and removal can only edge
The longitudinal direction for train is mounted and dismounted successively, it is necessary to will be close to headstock or the linear electric motors close to the tailstock are also unloaded successively,
The linear electric motors at middle part can just be taken out, therefore the maintenance workload after train marshalling list is big.Another medium-and low-speed maglev vehicle suspension
The support arm structure of frame equally uses integral structure.But this structure is for the ease of linear electric motors from suspension rack both sides direction
Take out, the main part of trailing arm is concentrated on the end of suspension rack.While the requirement in order to ensure structure and intensity, this structure
Occupy linear electric motors increases the space of length in longitudinal direction.Therefore, although this support arm structure is easy to tearing open for linear electric motors
Dress, but limit the length of linear electric motors, so that the peak power of suspension rack from ceiling structure.
Utility model content
The utility model provides a kind of medium-and low-speed maglev vehicle suspension frame torr arm configuration, and it can efficiently solve existing trailing arm
The accuracy of manufacture that structure is present requires that high, structural stability is not enough, disassembling and assembling machine is inconvenient, motor length is limited and adjacent motor
The problems such as being spaced larger.
The purpose of this utility model is achieved through the following technical solutions：A kind of medium-and low-speed maglev vehicle suspension frame torr
Arm configuration, including the longeron being connected with trailing arm, trailing arm top are irregular " isosceles triangle " structure, are somebody's turn to do the upward position of " isosceles triangle "
Provided with the first boss structure as tenon, the cross section of first boss structure is " three-back-shaped ", uniform two row in its four surfaces
Screw；The left and right sides for being somebody's turn to do " isosceles triangle " is hollow structure, is provided with close to first boss structure side and is used as the second of tenon
Boss structure, two be vertical angle adjacent to side, and the cross section of second boss structure is also " three-back-shaped ", its four surface uniform two
Arrange screw；Opposite side is the quadrilateral shape that two horizontal planes are insertion plane；Trailing arm bottom is " Г fonts " knot with mounting seat
Structure, it is the mortise with first boss respective outer side edges, its uniform two exhausting hole in four surfaces, " Г fonts " to be somebody's turn to do " Г fonts " horizontal ends
Vertical end be provided with mounting seat, square position is band muscle inclined-plane.
Coordinated between the trailing arm top and trailing arm bottom by boss structure joggle, and be fastened by bolts.
Coordinated between the trailing arm top and longeron by second boss structure joggle, and be fastened by bolts.
, also can be using as tenon second boss structure setting, in longeron end, trailing arm top is with indulging during the joggle coordinates
Coordinated between beam end by second boss structure joggle, and be fastened by bolts；Also tenon first boss structure will can be used as
The horizontal ends of trailing arm bottom are arranged at, are coordinated between trailing arm top and trailing arm bottom by first boss structure joggle, and pass through
Bolt is fastened.
Further limit, the tenon that trailing arm top coordinates with trailing arm bottom, i.e. the four of first boss structure surface has
Screw corresponding with four surfaces of mortise of trailing arm bottom.
Further limit, the mortise coordinated with trailing arm top of trailing arm bottom, i.e. the four of mortise surface has and trailing arm
The tenon on top, the i.e. corresponding through hole of first boss structure.
The beneficial effects of the utility model are：
The integral type trailing arm knot of existing maglev vehicle is being instead of using this medium-and low-speed maglev vehicle suspension frame torr arm configuration
After structure and flange, when the linear electric motors of suspension rack need demolition and maintenance in the middle of traveling portion mechanism, only need to turn on trailing arm bottom with
If the bolt stem between trailing arm top on joggle interface, you can trailing arm bottom is removed, enough spaces can be possessed and carry out straight line
The dismounting and installment work of motor, greatly reduce maintenance cost, are brought great convenience to attendant；Eliminate in the past
Welding deformation, reduce alignment error；The vacant linear electric motors of trailing arm increase the space of length in longitudinal direction, it is allowed to straight line
The raising of motor length, the lifting for suspension rack peak power provides possibility, while so that the linear electric motors of two adjacent suspension racks
Interval is smaller, and its end effect is reduced to a certain extent, electric efficiency is improved.
