Detailed description of the invention
" longitudinally " of the present invention refers to the direction that articulated car extends, and is also articulated car and runs
The rectilinear direction at place, direction, " laterally " then refers to direction vertical with " longitudinally " in horizontal plane.
Fig. 2 is the top view of articulated car underframe embodiment of the present invention；Refer to Fig. 2, the present embodiment carries
Supply a kind of articulated car underframe, including: the crossbeam 31 of horizontal expansion, and longitudinally through crossbeam 31
Central sill 32, crossbeam 31 and central sill 32 include the central sill cover plate 320 at top cross-bar cover plate 310 and top respectively,
Crossbearer cover plate 310 includes the splitted cover board 311 being positioned at central sill cover plate 320 both sides, splitted cover board 311 and central sill
Cover plate 320 is welded and fixed, and the forward and backward side of crossbearer cover plate 310 formed with central sill cover plate 320 vertical
Arc transiting surface 33 to the side smooth engagement extended.
Specifically, central sill 32 may be located on the vertical central axis of underframe, and crossbeam 31 may be located at central sill
The midpoint of 32 is also arranged with central sill 32 square crossing；Wherein, central sill 32 and crossbeam 31 are the most permissible
Use welded steel structure, i.e. central sill 32 can include at the bottom of the central sill of the central sill cover plate 320 at top, bottom
Plate and be welded between central sill cover plate 320 and central sill base plate and the middle web that is positioned at both sides, to enclose
Become hollow, the uiform section steel construction of longitudinal extension；Crossbeam 31 can include top crossbearer cover plate 310,
The crossbeam base plate of bottom and be welded between crossbearer cover plate 310 and crossbeam base plate and the horizontal stroke that is positioned at both sides
Web, to form hollow, horizontal expansion uiform section steel construction；Further, central sill 32 and crossbeam
The thickness of 31 matches, so that central sill cover plate 320 and crossbearer cover plate 310 are in same level, central sill
Base plate and crossbeam base plate are in same level.
Further, assembling for convenience, central sill cover plate 320 can include two splitted cover boards 311, two
Individual splitted cover board 311 is symmetricly set on central sill cover plate 320 both sides, when by two splitted cover boards 311 respectively with in
After side, beam cover plate 320 both sides is welded and fixed, then form the crossbeam 32 of a horizontal expansion.
In the present embodiment, splitted cover board 311 leading flank and trailing flank are near one end of central sill cover plate 320 respectively
Form the transition cambered surface 33 of arc-shaped, and this transition cambered surface 33 end is just direct with central sill cover plate 320
Engage, i.e. only smooth, arc-shaped by one between splitted cover board 311 and central sill cover plate 320 side
Cross cambered surface linking, there are not other salient points.
Alternatively, the side of central sill cover plate 320 can also be tangent with transition cambered surface 33, say, that in
The side of beam cover plate 320 longitudinal extension is located just on the tangent line of transition cambered surface 33 end.
The articulated car underframe that the present embodiment provides, by making the forward and backward side of splitted cover board through arc-shaped
Transition face directly engages with central sill cover plate so that crossbearer cover plate no longer exists any with central sill cover plate weld
Raised points, thus avoid producing stress and concentrate, improve the fatigue life of weld seam, and also can be further
Preventing portion component of stress value is increased to the yield limit of crossbeam, and then improves the bearing capacity of crossbeam, it is to avoid
Beam deformation inefficacy.
The present invention also provides for the manufacture method of a kind of above-mentioned articulated car underframe, refer to Fig. 2, Fig. 3 and
Fig. 4, including:
Step 1, two splitted cover boards 311 of crossbearer cover plate 310 are respectively placed in central sill 32 both sides, and will
Splitted cover board 311 is welded and fixed with the side of 320 two longitudinal extensions of central sill cover plate；Wherein, splitted cover board 311
In longitudinal forward and backward side and be close at described central sill cover plate and be respectively formed with boss 102(such as Fig. 3
Shown in).
Splitted cover board 311 welds with the docking of central sill cover plate 320 i.e., for convenience, can be by splitted cover board 311
The adjacent leading flank in the side towards central sill cover plate 320 and trailing flank on reserve boss 102 respectively,
I.e. respectively process boss 102 towards the side of central sill towards adjacent two side transition positions at splitted cover board 311,
To increase the contact area of splitted cover board 311 and central sill cover plate 320 side, it is ensured that formed after being welded and fixed
Weldquality.
Splitted cover board 311 is pressed predeterminated position clamping after, can be by splitted cover board 311 towards central sill cover plate 320
Side weld with central sill cover plate and be secured together so that the splitted cover board 311 of central sill 32 both sides is collectively forming
The crossbearer cover plate 31 of one horizontal expansion.
Step 2, the boss 102 of the forward and backward side of splitted cover board 311 is ground away, to be formed and central sill
The transition cambered surface 33 of cover plate 320 smooth engagement.Outside for boss 102 part protruded is ground away so that it is
Remaining part forms a smooth arc surface, i.e. forms the transition cambered surface 33 shown in Fig. 4.
The method utilizing the present embodiment can process the articulated car underframe in previous embodiment.
The present embodiment provide articulated car underframe manufacture method, by splitted cover board first reserve boss,
Postwelding again by boss grinding to form round and smooth transition cambered surface, it is possible to achieve convenient, weld splitted cover board securely
With central sill cover plate, be additionally, since the crossbearer cover plate after welding between central sill for seamlessly transitting, no longer exist
Salient point or fin, thus generation stress can be prevented effectively from and concentrate, improve the fatigue life of weld seam；Further,
Also contribute to the bearing capacity of crossbeam, it is to avoid prematurely reach yield limit and cause beam deformation to lose efficacy.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, rather than right
It limits；Although the present invention being described in detail with reference to foregoing embodiments, this area common
Skilled artisans appreciate that the technical scheme described in foregoing embodiments still can be modified by it,
Or the most some or all of technical characteristic is carried out equivalent；And these amendments or replacement, and
The essence not making appropriate technical solution departs from the scope of various embodiments of the present invention technical scheme.
