Description
Technical field
The utility model relates to spoke technical field, relates in particular to a kind of bogie spoke structure.
Background technology
The load carrying ability of bogie is larger, build is also very large, can carry the article that weight is large, very convenient for transporting goods, for the supporting capacity that ensures that wheel is enough, load-carrying carriage wheel must have enough support strengths to bear the weight of whole car body, load-carrying carriage wheel own wt is very large now, and spoke thickness is very large, thereby ensures support strength, but weight can increase greatly again the oil consumption of bogie, therefore how in meeting bogie support strength, to alleviate wheel weight and become a difficult problem.Along with development and the progress of technology, people have developed the various structures that alleviate wheel mass gradually.
For example, Chinese patent Granted publication number: CN201333893Y, on October 28 2009 Granted publication day, discloses a kind of wheel, is composed of a fixed connection by wheel and spoke entirety, and spoke ecto-entad is fixed on the outward flange at the minimum position of wheel internal diameter.And for example, Chinese patent Granted publication number: CN201580208U, September 15 2010 Granted publication day, a kind of lightweight wheel spoke for automobile design is disclosed, spoke is frustum tubular, is evenly equipped with wind hole on bullet profile, and the reinforced rib between adjacent wind hole forms indent or outer male structure, make overall bullet profile form concavo-convex alternate shape, strengthen the type spoke bulk strength with this.In the first scheme, only the change by connection location does not alleviate how much weight, the second is realized the object of removing material expendable weight by beat wind hole on conical suface, the conical surface is spoke and the bearing surface that is connected of wheel rim, after wheel pressurized, conical surface place can form two component, obviously can affect wheel strength at this position borehole, especially, for bogie, in driving process, have larger potential safety hazard.
Utility model content
The utility model is large in order to overcome bogie wheel weight of the prior art, and the deficiency that oil consumption is large, provides a kind of support strength to satisfy the demands, and quality is light, and energy actv. reduces the bogie spoke structure of vehicle oil consumption.
To achieve these goals, the utility model adopts following technical scheme:
A kind of bogie spoke structure, comprise circular disc, the round platform bearing surface that described disc around stretches out and forms, the center of disc is provided with mounting hole, disc is along being circumferentially also evenly provided with some bolts hole, round platform bearing surface is provided with wind hole, the end of described round platform bearing surface extends to form the welding anchor ring being connected with wheel rim, front web face is provided with outer loss of weight circular groove around, the described outer wall of outer loss of weight circular groove and the periphery of spoke connect, the position of the inwall of outer loss of weight circular groove between two adjacent bolts hole forms arc notch to disc central concave, described arc notch is greater than the width between centers of bolt hole and disc to the shortest distance at disc center, the bottom of outer loss of weight circular groove is the 1/2-2/3 of disc integral thickness to the thickness of disc medial surface, the surrounding that is positioned at mounting hole on described front web face is also provided with loss of weight circular groove.
Disc, round platform bearing surface are integral type structure, by punching press, bending forming, junction stress is concentrated, add bogie pressure large, stress raiser easily cracks, in this structure, offered outer loss of weight circular groove at this place, the inwall of outer loss of weight circular groove also has arc notch, make like this stress dispersion at disc edge go out, prevent stress raisers and ftracture, outer loss of weight circular groove, interior loss of weight circular groove have alleviated the weight of spoke significantly simultaneously, have reduced the oil consumption of bogie; During due to vehicle wheel rotation, be subject on the one hand the propulsive effort of wheel hub, be subject on the other hand the friction force of bottom surface, thereby whole spoke is along circumferentially having larger torsion, arc notch is greater than the width between centers of bolt hole and disc to the shortest distance at disc center, can ensure like this torque resistant ability that disc is enough.
As preferably, described interior loss of weight circular groove bottom surface is the 1/2-2/3 of disc integral thickness to the thickness of disc medial surface, the inwall of interior loss of weight circular groove and mounting hole connect, the outer wall upper end of interior loss of weight circular groove is connected with front web face arc transition, and the outer wall lower end of interior loss of weight circular groove is connected with bottom surface arc transition.Interior loss of weight ring plays loss of weight effect on the one hand, also can reduce on the other hand mounting hole stress around and concentrate.
As preferably, the minor increment between described arc notch and interior loss of weight circular groove is more than or equal to 2 times of diameter of bolt hole.The Joint strenght of bolt and bolt hole cooperation place on guarantee disc.
Therefore, the utility model tool is lightweight, oil consumption is little, and the stress that reduces disc and round platform bearing surface junction is concentrated, and improves the beneficial effect of spoke overall performance.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is A-A place cutaway view in Fig. 1.
Fig. 3 is B place partial enlarged drawing in Fig. 2.
In figure: the interior loss of weight circular groove 102 of outer loss of weight circular groove 100 arc notch 101 of anchor ring 6 is welded in disc 1 round platform bearing surface 2 mounting hole 3 bolt hole 4 wind holes 5.
