Description
Technical field
The utility model is related to medium-and low-speed maglev technical field of vehicle, particularly suspension rack design and manufacturing technology field.
Background technology
Medium-and low-speed maglev train is relative to wheel-rail train and high-speed maglev train, with safety, economy, peace and quiet, green etc.
Distinguishing feature.Its every kilometer cost and operation expense are below subway and light rail, and current China Changsha is existing one
Medium-and low-speed maglev train puts into commercial operation, and the ground such as Sichuan Chengdu also has among medium-and low-speed maglev train builds or plan.
In existing medium-and low-speed maglev vehicle suspension frame design, trailing arm and vertical sled are usually placed in the two of longeron
End.The medium-and low-speed maglev vehicle suspension frame design of this arrangement has the following disadvantages：As shown in figure 1, due to load
Concentrate in the middle part of longeron, existing arrangement make it that the static deflection amount of the longeron of suspension rack is relatively large, the end of suspension rack
Different occurs in the levitation gap at portion and middle part, and position of the levitation gap sensor on suspension rack is usually fixed
, therefore due to the influence of system amount of deflection, the measurement horizontal plane between electromagnet and F rails can be made different gaps occur so that outstanding
Floating controller can not be accurately controlled levitation gap, influence the suspension stability of system.In addition, middle part levitation gap is too small
Levitating electromagnet can be easily caused to be collided with F rails again, so as to damage the parts such as levitating electromagnet.
Utility model content
The purpose of this utility model is to provide a kind of medium-and low-speed maglev vehicle suspension frame, and it is quiet that it can efficiently solve suspension rack
The problems such as state assembly deflections amount is larger, suspension stability is not enough.
The purpose of this utility model is achieved through the following technical solutions：A kind of medium-and low-speed maglev vehicle suspension frame,
Longeron and anti-rolling sill component including left and right setting, the vertical center line both sides of side rail inner are respectively provided with one group of anti-rolling sill
Mounting seat, anti-rolling sill component connects and composes suspension rack by mounting seat and longeron, and linear electric motors are located at the lower section of longeron.Longeron
Lateral surface and mounting seat correspondence position be equipped with boss structure as tenon, the horizontal ends of trailing arm are the lateral surface with longeron
The mortise that boss structure coordinates, its uniform two exhausting hole in four surfaces, trailing arm coordinates with the boss structure joggle, and passes through bolt
It is fixed；The medial surface of longeron is respectively equipped with vertical sled close to end position.
The cross section of the boss structure is " three-back-shaped ", and the horizontal end of uniform two row in its four surfaces and trailing arm is led to
The corresponding screw in hole.
The anti-rolling sill mounting seat is provided with lightening recesses and lightening hole.
This trailing arm middle medium-and low-speed maglev vehicle suspension frame, left and right longeron is connected by two groups of symmetrical anti-rolling sills
Connect composition；Coordinated between left and right longeron and trailing arm by the boss structure joggle on the outside of longeron on vertical surface, and pass through bolt
Fastening；Four vertical sleds are located at mortise structure of the side rail inner on the outside of end position, longeron in longeron transverse direction
Heart face is arranged symmetrically.The uniform two rows screwed hole of boss structure surrounding, for being connected with trailing arm.Longeron upper surface middle part position is provided with
The circular groove structure coordinated with air spring chuck.This simple in construction, safe and reliable, production cost is low, be easy to dismounting to tie up
A kind of trailing arm middle medium-and low-speed maglev vehicle suspension frame of the smaller assembly deflections amount of shield,
The beneficial effects of the utility model are：Being located proximate to of boss structure on the outside of longeron and matched trailing arm is indulged
It is simple and reliable for structure so that load is uniformly distributed as far as possible in the middle part of beam, longeron assembly deflections amount during reaching full and down operation
It is required that, protect levitating electromagnet；Trailing arm is coordinated with longeron using joggle, is easy to the dismounting of linear electric motors, and be long straight-line electric
Machine provides adequate space, and the end effects of linear electric motors is reduced while preferably lifting the driving force needed for train operation；
Suspension rack uses long longitudinal beam structure, if longeron end is without bolt hole and its relevant position bolt stem, screw being connected with trailing arm etc.
Standard component, so as to reach the requirement of light-weight design so that integral arrangement is more succinct, attractive in appearance.

Fig. 3 is the schematic diagram of anti-rolling sill mounting seat in the utility model.
Fig. 4 is simulation curve of the vertical deflection of the longeron end of the utility model and prior art in curve negotiating
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in figure 1, this trailing arm middle medium-and low-speed maglev vehicle suspension frame mainly includes two longerons that left and right is set
1st, the part such as two sets of anti-rolling sill components 2, four trailing arms 3 and four vertical sled 4 constitutes trailing arm middle medium-and low-speed maglev
Vehicle suspension frame, includes the longeron 1 and anti-rolling sill component 2 of left and right setting, and the vertical center line both sides of the inner side of longeron 1 are respectively set
There is one group of anti-rolling sill mounting seat 7, anti-rolling sill component 2 connects and composes suspension rack, linear electric motors 6 by mounting seat 7 and longeron 1
Positioned at the lower section of longeron 1.The lateral surface of longeron 1 is equipped with the boss structure 5 as tenon, trailing arm 3 with the correspondence position of mounting seat 7
Horizontal ends be the mortise coordinated with the lateral surface boss structure 5 of longeron 1, its uniform two exhausting hole in four surfaces, trailing arm 3 with should
The joggle of boss structure 5 coordinates, and is bolted；The medial surface of longeron 1 is respectively equipped with vertical sled 4 close to end position.
The cross section of the boss structure 5 is " three-back-shaped ", uniform two row in its four surfaces and the horizontal end of trailing arm 3
The corresponding screw of through hole.Each lateral surface center line both sides of longeron 1 are provided with left and right symmetrical boss structure 5 as tenon, and it four
