Description
Technical field
The present invention relates 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 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
Among the ground such as the input commercial operation of medium-and low-speed maglev train, Sichuan Chengdu also have medium-and low-speed maglev train building or planning.
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
Longeron middle part is concentrated on, existing arrangement causes that the static deflection amount of the longeron of suspension rack is relatively large, the end of suspension rack
The levitation gap at portion and middle part occurs different, 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.
The content of the invention
It is an object of the invention to provide a kind of medium-and low-speed maglev vehicle suspension frame, it can efficiently solve the static dress of suspension rack
With deflection it is larger, suspension stability is not enough the problems such as.
The purpose of the present invention is achieved through the following technical solutions：A kind of medium-and low-speed maglev vehicle suspension frame, including
The longeron and anti-rolling sill component of left and right setting, the vertical center line both sides of side rail inner are respectively provided with one group of anti-rolling sill and install
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.Outside longeron
Side is equipped with as the boss structure of tenon with mounting seat correspondence position, and the horizontal ends of trailing arm are the lateral surface boss with longeron
The mortise of respective outer side edges, its uniform two exhausting hole in four surfaces, trailing arm coordinates with the boss structure joggle, and solid by bolt
It is fixed；The medial surface of longeron is respectively equipped with vertical sled near end position.
The cross section of the boss structure is " three-back-shaped ", and uniform two row in its four surfaces is led to the horizontal end of trailing arm
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 by the boss structure joggle on vertical surface on the outside of longeron between left and right longeron and trailing arm, and by bolt
Fastening；Four vertical sleds are located at side rail inner near end position, and the mortise structure on the outside of longeron is 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 structure, safe and reliable, low production cost, be easy to dismounting 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 invention are as follows：Boss structure and matched trailing arm on the outside of longeron are located proximate in longeron
Portion, simple and reliable for structure so that load is uniformly distributed as far as possible, longeron assembly deflections amount will during reaching full and down operation
Ask, protect levitating electromagnet；Trailing arm is coordinated with longeron using joggle, is easy to the dismounting of linear electric motors, and be linear electric motors long
Adequate space is provided, the end effect of linear electric motors is reduced while driving force needed for preferably lifting train operation；It is outstanding
Scaffold uses longitudinal beam structure long, if longeron end is marked without bolt hole and its relevant position bolt stem, screw being connected with trailing arm etc.
Quasi- part, so as to reach the requirement of light-weight design so that integral arrangement is more succinct, attractive in appearance.

Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the schematic diagram of vertical sled in the present invention；
Fig. 3 is the schematic diagram of anti-rolling sill mounting seat in the present invention.
Fig. 4 is the simulation curve with the vertical deflection of longeron end of prior art in curve negotiating of the invention
Specific embodiment
The present invention is further described 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 sleds 4 constitutes trailing arm middle medium-and low-speed maglev
Vehicle suspension frame, including left and right setting longeron 1 and anti-rolling sill component 2, the vertical center line both sides of the inner side of longeron 1 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 as the boss structure 5 of 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 near end position.
The cross section of the boss structure 5 is the horizontal end of " three-back-shaped ", uniform two row in its four surfaces and trailing arm 3
The corresponding screw of through hole.Each lateral surface center line both sides of longeron 1 is provided with left and right symmetrical boss structure 5 as tenon, and it four
The individual uniform two rows screw in surface；The end of trailing arm 3 is provided with corresponding mortise, and its four surfaces are provided with through hole corresponding with tenon；It is convex
Coordinated by joggle between the mortise of platform structure 5 and the end of trailing arm 3, blending bolt fastening.Biggest advantage is great side
Linear electric motors long 6 installation and removal.After being coordinated using joggle, when needing to carry out the dismounting of linear electric motors 6 and install,
The joggle interface between boss structure 5 and trailing arm 3 need to only be opened, trailing arm 3 is unloaded, you can obtain enough spaces by straight line
Motor 6 is installed or removed from suspension rack both sides.Under this configuration, the installation of linear electric motors 6, maintenance and dismounting are all very square
Just, cost has greatly been saved.
