Detailed description of the invention
Below with reference to accompanying drawing and describe this utility model in detail in conjunction with the embodiments.It should be noted that do not conflicting
In the case of, the embodiment in this utility model and the feature in embodiment can be mutually combined.For sake of convenience, the most such as
Occur " on ", D score, "left", "right" printed words, only represent consistent, not to structure with the direction, upper and lower, left and right of accompanying drawing itself
Play restriction effect.
A kind of 100% low-floor tramcar bogie, as it is shown in figure 1, bogie main body mainly by framework 1, wheel to 2, drive
Moving cell 3, secondary suspension 4 etc. form.Wherein:
As in figure 2 it is shown, framework is by carrying underframe 11, journal box spring installation supporting leg 12, driver element installation longeron 13 assembly welding
Forming, each subassembly is become case type closed girder construction by Plate Welding, and entirety meets intensity, rigidity requirement.
Driver element is installed longeron 13 and the supporting leg 12 of axle box installation front and back is connected into an entirety, improves the firm of framework
Degree, reduces framework flexural deformation in the vertical.
Lateral damper mounting seat, horizontal backstop mounting seat, anti-sidewinder device mounting seat integrated 14, be welded on underframe
Middle part, decreases amount of parts, and integration degree is high.
Vertical damper bearing 15 is positioned at four corners of underframe, is connected with underframe riser by welding.
Take turns and become by axletree, elastic wheel, axle box, bearing, circular cone rubber axle box groups of springs.Circular cone rubber journal box spring is pacified
It is contained in the mounting seat that framework journal box spring is installed on supporting leg, between circular cone rubber journal box spring and mounting seat, takes transition to join
Close.This utility model takes minor diameter monolithic wheel that, driver element is longitudinally mounted to lateral wheel, and axle box is arranged in wheel
Side.
Driver element 3 has two sets, is respectively used to drive front and back wheel pair.Often set driver element is by motor, gear-box, shaft coupling
Device, flexible coupling form, and motor is bolted into a rigidity entirety with gear box casing, by three elastic installations
Point is installed longeron with framework driver element and is connected.Gearbox output shaft is connected with wheel by flexible coupling, transmits moment of torsion.
Secondary suspension plays connection bogie and car body, the effect of the power in all directions between transmission bogie and car body.
As shown in Figure 3, Figure 4, secondary suspension by four two be rubber hourglass spring 42, two horizontal backstops 43 of 41, four vertical dampers,
Two lateral dampers 44, single longitudinal traction pull bars 45 and anti-sidewinder device 46 and form.
Two lateral dampers are arranged on median plane, and bottom mount point is connected with framework by bolt, and vibroshock is oblique
Upper installation, is symmetrical arranged with bogie transverse center face X.Two horizontal backstops lay respectively at above two lateral dampers, logical
Cross bolt to be connected with framework.The layout that such a is symmetrical makes the transmission of cross force between car body with framework compare equilibrium.
Thus, four vertical dampers are arranged between framework and car body, and vibroshock mount point architecturally is positioned at the end
Four corners of frame, relative to being arranged in framework rear and front end, its installation site serpentine locomotion amplitude architecturally is little, this
Sample has been reduced by being passed to the vibration of car body by vertical damper, improves vehicle cruising characteristic.
Two lateral dampers are arranged between framework and car body, and framework mount point is positioned in the middle part of underframe, horizontal with bogie
It is arranged symmetrically with to median plane, the horizontal damping force of transmission can be equalized, and the installation site that lateral damper is architecturally can reduce
Passed to the vibration of car body by lateral damper, thus improve vehicle cruising characteristic.Two lateral dampers are used to reduce
The requirement of single shock absorber damping, can improve the service life of lateral damper.
The content that above-described embodiment illustrates should be understood to that these embodiments are only used for being illustrated more clearly that this utility model,
Rather than limit scope of the present utility model, after having read this utility model, those skilled in the art are new to this practicality
The amendment of the various equivalent form of values of type each falls within the application claims limited range.
