Description
Technical field
This utility model relates to the articulated mounting of rotating hinge, is specifically related to one and is combined with metal joint bearing by mandrel seat
The articulated mounting become.
Background technology
At present, along with the increase of urban passenger flow amount, low-floor light rail vehicle more piece is hung and make-up type is flexible and changeable also
Become inexorable trend, and the floor of low floor vehicle is relatively near away from rail level, there is no traditional hitch space, and urban inner
Track traffic route has the advantages that sweep is little and ramp is steep and many, is badly in need of low-floor rail vehicle attachment means, and cuts with scissors
Connection device can fully meet above-mentioned requirements.
Low floor vehicle articulated mounting, is arranged in coupling part, car body two ends, and fit system is cut with scissors in general employing up and down, by respectively
Articulated mounting limits body movement, makes low floor vehicle have good sharp radius curve ability excessively.Hand over simultaneously as future city
The logical transport main force, the low floor vehicle city that got more and more uses.And articulated mounting is as the important functional part of low floor vehicle, its
Developmental research the most increasingly draws attention.
Between the underbody of low-floor train adjacent compartment, general employing fixes hinge device, typically uses between the roof of adjacent compartment
Rotating hinge device, wherein the fixing hinge device of underbody limits the translation in three directions, it is allowed to three directions rotate, and bear train
Vertical force, the transmission most longitudinal traction of adjacent train (current of traffic) and cross force；Used between roof and turned
Dynamic articulated mounting allows adjacent train spaced winding vertical axis to rotate, and provides vertical and horizontal firm by device inner rubber parts
Degree, it, by coordinating underbody to fix articulated mounting, bears the part longitudinal traction of train, limits sidewindering between adjacent car body
With motion of nodding, make between adjacent train, to only exist the degree of freedom relatively shaken the head, meet city small curve radius requirement, be full simultaneously
Steep gradient requirement crossed by foot train, replaces rotating hinge dress using free articulated device every between the adjacent train roof of certain joint number
Put.
Low floor vehicle car body is connected by upper and lower articulated mounting.The low floor vehicle vehicle used in the market is different, right
The requirement of rotating hinge welding system is the most varied.But low floor vehicle is owing to using requirement, each vehicle to the load of articulated system and
Movement needs is the most substantially similar.And will redesigning for each vehicle rotating hinge system in the market, and 26S Proteasome Structure and Function
Different.For above-mentioned requirements, this patent is by designing the rotational articulated device of a kind of new structure so that low floor vehicle can
Safety and steady by level curve and vertical curve.And low for general low floor vehicle rotating hinge system versatility ability,
The shortcomings such as demolition and maintenance difficulty, maintenance cost are high, manufacture the rotational articulated device of a kind of angle adjustable.
This utility model develops a kind of novel low-floor rail vehicle roof rotational articulated device, limits adjacent car body
Between motion of sidewindering and nod, make between Adjacent vehicles, to only exist the degree of freedom relatively shaken the head, transmission to pull strength and improve car
City small curve radius requirement is met while running comfort.
Find that following patent and the present invention have a similarity by domestic retrieval:
Application No. 200920015082.1, entitled " elastic hinging device for hinging urban low-floor railway vehicles "
Utility model discloses a kind of being coupled together by more piece low floor vehicle for urban track traffic and forms the hinged of elasticity marshalling
A kind of elastic hinge joint device in mechanism, is hinged for elastic ball, and radial rigidity is relatively big, and torsional rigidity is less.It is lowly

As depicted in figs. 1 and 2, upper bulb 2 and lower bulb 3 are all enclosed within the outer ring, joint 62 of metal joint bearing 6, and under
The longitudinal section of the upper end of bulb ring 31 and the lower end of upper bulb ring 21 is zigzag, and the lower end of upper bulb ring 21 is embedded in lower bulb ring
In the upper end of 31.By connecting bolt 312 through union joint 311 and after tightening, bulb ring 21 and lower bulb ring 31 can be made
Inner side all holds outer ring, joint 62 tightly, so that upper bulb 2 and lower bulb 3 can be with outer ring, joint 62 around joint inner rings 61 turns
Dynamic.Therefore can realize rotating hinge in horizontal, longitudinal and vertical rotation, thus realize low floor vehicle can little by sweep and
The circuit that ramp is steep.
Shown in as shown in Figure 1, Figure 3 and Figure 4, upper bulb 2 and lower bulb 3 are all by connecting rod 4 and rubber bulb 8 and lower bottom base 92
Connecting, upper bulb 2 and lower bulb 3 are in the shape of the letter V and are fixed on metal joint bearing 6.Angle between upper bulb 2 and lower bulb 3
It is adjustable, is connecting bolt 312 first to unclamp, then allows bulb 2 relative turning occurs with lower bulb 3 when regulating described angle
Dynamic, tighten connecting bolt 312 after mixing up angle again.
As in figure 2 it is shown, in order to prevent mandrel seat 1 and metal joint bearing 6 from relative movement occurring, prevent metal joint bearing
6 scurry out from mandrel seat 1.Open a ring-type notch 111 in one end of the shaft core 11 of mandrel seat 1, shaft block ring 52 is arranged on
In notch 111 so that metal joint axle and shaft block ring 52 phase top, thus play the anti-effect scurried out.For preventing rainwater, dust
Invading in rotating hinge Deng foreign material, be provided with dust ring 51 in the outside of mandrel seat 1, the longitudinal section of dust ring 51 is fold-line-shaped；Mandrel
One end of seat 1 is additionally provided with end cap 7, is fixed end cap 7 with bolt of cover 71；For strengthening the effect sealed also at end cap 7
It is provided with sealing ring to seal.
It will be apparent that on the premise of without departing from principle described in the utility model, some improvement or the modification made all should regard
For protection domain of the present utility model.
