In addition, (especially, as can be seen from Figure 5), because the setting at elementary suspension interface 110 consequently acts on the supporting power F of general branch in free end 108.1 zones
TRS(namely when running gear framework 104 was supported on wheel unit 103, the total of bearing force who acts on free end 108.1 zones by elementary suspension gear 105 made a concerted effort) is generally about the xz plane parallel, simultaneously with an elementary suspension angle α

Tilt about short transverse (z axle), thereby realized reducing in a large number of space (running gear 102 middle frame main bodys 107 being required).Compare this supporting power F of general branch with the structure among DE41 36 926A1
TRSInclination allow these elementary suspension gear 105.1 more close wheel sets 103, more precisely, the rotation axis 103.2 of more close wheel set 103.The advantage of this method not only comprises: elementary suspension interface 110 can more close wheel unit, has saved significantly the shared space of central part of running gear 102.In addition, the pivot arm 112 that is connected to wheel set bearing unit 103.2 can be a kind of less, lighter and simpler design.
In addition, be included into herein for your guidance according to the whole open text of the pending patent No. 10 2,011 110 090.7() German patent application in the more detailed description details, the supporting power F of general branch of this inclination
TRSCan improve at the pivot interface 111 realize connection that pivot arms 112 are connected with chassis body may, pivot arm and chassis body all be that the lower self-control of load is (owing to act on total with joint efforts F on longitudinal direction and the short transverse
TRSComponent), ought not have support load F simultaneously
TRSShi Rongyi is disassembled.
At last, the advantage of this design is: especially because interface portion is more right near wheel, it has promoted the automated production that passes through the automation casting method of chassis body further.
Basically, although the supporting power F of general branch
TRSInclination about longitudinal direction and short transverse any needs, suitable can be arranged, in the present embodiment, the supporting power F of general branch
TRSWith an elementary suspension angle α
PSF, x=45 ° are tilted about longitudinal direction.Therefore, general branch's supporting power with one with the elementary suspension angles angle [alpha] of complementary angle each other
PSF, z=90 °-α
PSF, x=45 ° are tilted about short transverse.Therefore, this inclination provides compact, a favourable especially design.In addition, it is also better with support load F
TRSBe applied on the framework cylinder 107 from wheel set 103.At last, therefore, column sections or end 108.1 can be a kind of structure that leans forward slightly, and it is conducive to promote the fluidity of cast material and the use of automation casting method.
From Fig. 5, can find out further, since the setting of elementary suspension interface 110 and elementary suspension gear 105.1, the supporting power F of general branch
TRSA wheel countershaft 103.3 that runs through wheel set 103 causes support load to be applied to elementary suspension gear 105.1 and onwards to be applied to chassis body 107 from wheel set 103 better.More precisely, general branch's supporting power F
TRSThe rotation of wheel axis 103.2 that runs through axletree 103.3.
In addition, this structure makes the supporting power F of general branch
TRSThrow of lever lack (for example, the throw of lever A at pivot bolt 113.1 places
TRS), therefore also make the moment of deflection that acts on longeron 108 lower, it allows a kind of lighter design of chassis body 107 conversely.
The further advantage of the above structure is that pivot arm 112 can be a kind of very simple and compact design.More precisely, in the present embodiment, integrate except pivot arm 112 need of the wheel set bearing unit 103.1 of fork (pivot bolt 113.1 usefulness are installed) and provide a corresponding stayed surface for the primary spring arrangement 105.1 of the periphery that is positioned at close wheel set bearing unit 103.1 simply.Therefore, compare with existing structure, do not need complicated arm or like that bearing force is applied to primary spring arrangement 105.1.
Basically, although elementary suspension interface portion 110 can have shape any needs, suitable, in the present embodiment, elementary suspension interface portion 110 is a simple flat surfaces 110.1, its both sides be two projection 110.2(in addition, for reaching purpose placed in the middle, stand near described projection in the surface that elementary suspension gear 105.1 matches with it).This flat surfaces 110.1 has defined a main interface plane, and this main interface plane has been born a part of supporting power F of general branch
TRS
Main interface plane 110.1 and the supporting power F of general branch
TRSSubstantially vertical and substantially parallel with horizontal direction (y axle).Therefore, main interface plane 110.1 tilts about longitudinal direction and tilts about short transverse.More precisely, main interface plane 110.1 tilts about short transverse with main interface plane angle

Therefore, in the present embodiment situation, main interface plane 110.1 is with main interface plane angle [alpha]

As can be seen from Figure 3, in a cross section that is parallel to the xz plane, each crossbeam 109.1 is provided with a cross-sectional plane that is roughly C shape with an interior wall 109.2, a upper wall 109.3 and a lower wall 109.4.The set-up mode of this C shape cross-sectional plane is, in a longitudinal direction, its opening is towards the free end of (being positioned at nearer) chassis body 107, and it is generally by the interior wall adjacent with the center of chassis body 107 109.2 sealings simultaneously.In other words, the open side of crossbeam 109.1 deviates from mutually.
The advantage of this opening design of crossbeam 109.1 is (although the material therefor rigidity is general), not only single crossbeam 109.1 reverse comparatively soft, i.e. torque resistant rigidity about horizontal y axle lower (comparing with the general sealing of crossbeam, the design of box-like).Because interior wall 109.2(is in a longitudinal direction) comparatively be positioned at comparatively speaking the center of crossbeam unit 109, this point also is applicable to crossbeam unit 109 as a whole, so they are less about the antitorque moment impact of horizontal y axle.
In addition, the gap 109.5 that is positioned at chassis body 107 central areas is provided with a maximum axial clearance size L
G, max, it is one minimum longitudinal size L in the crossbeam 109.1 on the longitudinal direction
TB, min100%(be positioned at the central area of chassis body 107).The advantage in gap 109.5 is that under the prerequisite that does not increase chassis body 107 quality, the bending stiffness of (being parallel to the xy-plane) has increased in the main extended surface of two crossbeams 109.1, has therefore realized a kind of lighter structure.
In addition, gap 109.5 can be easily be used for other parts (for example transverse damper shown in Fig. 6 114) of installation and operation device 102, and it is particularly conducive in the modern guideway vehicle the strict restriction about available space.
C shape cross-sectional plane extends across a transverse center section of crossbeam unit 109, and this is because can produce on the torsion stiffness of crossbeam unit particularly advantageous impact on this position.。In the present embodiment, this cross-sectional plane that is roughly C shape extends across the whole extension (namely from a longeron 108 to another longeron 108) of crossbeam unit in a lateral direction.Therefore, in the present embodiment, this C shape cross-sectional plane extends across a horizontal size W
TBC, it is the transverse distance W of 108.4 of the longitudinal centerlines of the longeron 108 in zone, crossbeam unit 109
LBC85%.Even if use this ferrostell chassis body, also can realize in this way a kind of particularly advantageous torsion stiffness.
As for extension in a lateral direction, same (referring to C shape cross-sectional plane) also is applicable to the extension in gap 109.5.In addition, it is worthy of note that the size of axial clearance does not need identical with in a lateral direction.Can select required gap as required.
In the present embodiment, each crossbeam 109.1 has defined a crossbeam line of centers 109.6, and on the first plane that is parallel to the xy plane and being parallel in second plane on yz plane, it is generally shape curve or polygonal.This advantage that is generally crossbeam line of centers 109.6 curve or polygonal shape is, each crossbeam 109.1 is adapted to act on the load distribution of each crossbeam 109.1, thereby make the stress stationary distribution of 109.1 li on each crossbeam, and finally make lighter weight and the stress optimization of chassis body 107.
Therefore, can find out from Fig. 2 and Fig. 6 that crossbeam unit 109 is one and narrows the unit with a center of narrowing central part 109.7 that this narrows the minimum longitudinal size L that central part 109.7 has defined the crossbeam unit
TBU, min(in a longitudinal direction), in the present embodiment, minimum longitudinal size L
TBU, minMaximum longitudinal size L for the crossbeam unit
TBU, max(in a longitudinal direction) 65%.In the present embodiment, this maximum longitudinal size is defined within the junction of crossbeam unit 109 and longeron 108.
In general, the degree that narrows of crossbeam unit 109 can be selected as a kind of variable that concerns that chassis body 107 needs the mechanical characteristics (torsion stiffness that refers to especially chassis body 107) of realization.Under any circumstance, herein described crossbeam unit be designed to the good structure of a kind of balance and torsion stiffness lower (about horizontal direction) and counter-bending rigidity higher (about short transverse).Because running gear framework 104 can provide the certain torsional deflection of the wheel of all four wheels that tend to balance wheel set 103 to the contact force of track, this structure can be advantageous particularly to the Derailment Safety about running gear 102.
Can find out further that from Fig. 3 and Fig. 6 in the present embodiment, free end 108.1 forms of shutdown feature 115 and stops the interface in the part that deviates from elementary spring interface 110.Shutdown feature 115 has been integrated a rotation shutdown feature of car body 101.1 and the function of a vertical shutdown feature.In addition, shutdown feature 115 also is adapted to form a kind of tractions in chassis body 107 and 101.1 of car body on being connected chassis body 107 and connects.Should be pointed out that this structure is advantageous particularly because it provides a kind of Function Integration Mechanism of height and can realize a kind of lighter unit design.
As can be seen from Figure 1, car body 101.1(more precisely, or the same section of car body 101.1 is supported on the first running gear 102 or another part of car body 101) be supported on the second other running gear 116.Aforesaid all parts, the second running gear 116 is the same with the first running gear 102.Yet, when the first running gear 102 for a kind of during with (not indicating) slave operation device that is installed in the actuating device on the chassis body 107,116 of the second running gears be one without this non-slave operation device that is installed in the actuating device on the chassis body 107.
Therefore, according to another aspect of the present utility model, chassis body 107 has formed a standardized component for the first running gear 102 and the second running gear, i.e. dissimilar running gears.By specific type components additionally is installed, can realize being applicable to the customization of chassis body 107 of the particular type of running gear on standard card cage main body 107.This method has highly favourable business impact.This be because, the great amount of cost of in the automation foundry technique, saving, only need produce one type chassis body 107, it has further saved cost in large quantities.
Should be pointed out that again that on the basis of identical chassis body 107, the customization of running gear 102,106 particular type and function herein is not restricted to the difference of driven and non-slave operation device.On the basis of standardized identical frames main body 107, can use the parts (such as the drg of particular type, pitch system, rolling support system etc.) of other any function to realize function difference relevant between this running gear.
Although in preamble only take with built-in running gear of taking turns supplementary bearing as background is described the utility model, should be noted that the utility model also can be used for the situation of taking turns supplementary bearing with external.Only need to do slight change to the running gear framework and get final product, the position of the element such as longeron, magnetic brake particularly is to adapt to different gauges.
Although the utility model has only been made explanation take low-floor rail vehicle as background hereinbefore, yet should be pointed out that it also is applicable to the guideway vehicle of other any type, to solve about reducing the Similar Problems of production difficulty.
