But, in casting as in the wheel of the type in the hub for vehicle wheel portion of another parts, when applying moment of torsion, it is important that do not produce the difference in rotation direction between hub for vehicle wheel portion and wheel body.Therefore, at the outer peripheral face in hub for vehicle wheel portion, generally, circumferentially spaced be provided with multiple towards axially extended protuberance, when wheel body casts so that the raw material metal of wheel body is filled to the gap between protuberance.When adopting this hub for vehicle wheel portion, the broad area of the outer region in hub for vehicle wheel portion, the raw material metal contiguity of wheel body, meanwhile, outside diametric(al), rotational torque is delivered to wheel body by multiple hub portion of protuberance efficiently.
Then, in this wheel, for the difference in rotation direction between limiting wheel hub portion and wheel body more effectively, it is preferred to the axial length in hub for vehicle wheel portion to be grown, the projecting height of protuberance wants height.
But, if the axial length in hub for vehicle wheel portion is elongated, then the axial length that wheel is all is elongated, in order to avoid the interference with wheel, worries that the layout on other parts on car body produces impact, or is difficult to ensure that the space for loading and unloading wheel.
Additionally, when the projecting height of the protuberance in hub for vehicle wheel portion uprises, the degree of depth then forming the groove between adjacent protuberance deepens therewith, and when the hub for vehicle wheel portion that casts, casting wheel body, the inflow part degree of depth of the motlten metal of the groove being flowed between protuberance deepens.Therefore, with the solidification of motlten metal, it is easy to the near-bottom generation shrinkage cavity of groove between the projections.
Summary of the invention
Then, it is an object of the invention to, it is provided that realize the shortening of axial length and improve casting property, the wheel of the intensity of transmission moment of torsion between hub for vehicle wheel portion and wheel body can be improved simultaneously, and using the motorcycle of this wheel.
In order to solve above-mentioned problem, wheel involved in the present invention includes the hub for vehicle wheel portion 31 with the axle center hole 30 being arranged on axletree 20, and is cast into the wheel body 32 in above-mentioned hub for vehicle wheel portion 31 at axle center part, and above-mentioned hub for vehicle wheel portion 31 includes:
Major diameter basal surface 38, constitutes the outer peripheral face being biased against axial one end；
Minor diameter basal surface 39, constitutes the outer peripheral face being biased against the axial other end, and diameter is less than above-mentioned major diameter basal surface 38；
Inclined substrate face 40, connects above-mentioned major diameter basal surface 38 and above-mentioned minor diameter basal surface 39；And
Multiple first protuberances 45, separate configuration in outer region, and meanwhile, the scope that each leisure crosses over above-mentioned inclined substrate face 40 from above-mentioned major diameter basal surface 38 axially extends.
Thus, when the hub for vehicle wheel portion 31 that casts casts wheel body 32, if motlten metal is flowed into the outer peripheral face in hub for vehicle wheel portion 31 in shaping mould, then this motlten metal encases the first protuberance 45 crossing over major diameter basal surface 38 and inclined substrate face 40 extension, and is filled between the first adjacent protuberance 45.In this condition, if motlten metal cooling, then motlten metal starts solidification from the exterior side of wheel body 32, and the outside leaving wheel body 32 is more remote, and the solidification of motlten metal is more slow.Therefore, if leaving the distance of the outside of wheel body 32, it is susceptible to shrinkage cavity in this part, but when this wheel, cross over inclined substrate face 40 due to the first protuberance 45 from the major diameter basal surface 38 in hub for vehicle wheel portion 31 to extend, therefore, the degree of depth forming the groove between the first adjacent protuberance 45 will not be deep, and shrinkage cavity is difficult to produce.
Such as, when the external diameter that the basal surface Zone Full of the outer peripheral face in hub for vehicle wheel portion is certain, when the periphery of this basal surface extends multiple protuberance of substantially certain altitude, if not making the degree of depth of groove between high, the adjacent protuberance of the height of protuberance enough deep, just it is difficult to ensure that between hub for vehicle wheel portion and wheel body for transmitting intensity necessary to moment of torsion.But, in wheel involved in the present invention, remote position is left towards radial outside in the axle center that major diameter basal surface 38 is positioned at from hub for vehicle wheel portion 31, first protuberance 45 is crossed over inclined substrate face 40 from this major diameter basal surface 38 and is extended, therefore, even if the projecting height of the first protuberance 45 is not region-wide high, it is also possible to guarantee between hub for vehicle wheel portion 31 and wheel body 32 for transmitting the intensity of moment of torsion.Especially, the region extended in inclined substrate face 40 among the first protuberance 45, become with the axis of protuberance with hub for vehicle wheel portion 31 compared with extending parallel to occasion, if the scope of same axial, be then able to ensure that development length is long.Therefore, shortening the axial length occasion in hub for vehicle wheel portion 31, the projecting height that also can not make the first protuberance 45 is high, increases the contact area of itself and wheel body 32, it can be ensured that for the enough intensity of moment of torsion transmission.Therefore, in wheel involved in the present invention, the degree of depth owing to forming the groove between the first adjacent protuberance 45 is not deep, therefore, and the generation of shrinkage cavity when also can suppress to cast.
Can also on above-mentioned major diameter basal surface 38, between multiple above-mentioned first protuberance 45 that circumference is adjacent, arrange axially extend, the second protuberance 46 that above-mentioned first protuberance 45 of aspect ratio is low.
This occasion, between the first multiple protuberance 45 that circumference is adjacent, by the second protuberance 46 that aspect ratio the first protuberance 45 is low, it is possible to increase the contact area between hub for vehicle wheel portion 31 and wheel body 32.
It is also possible that the end of above-mentioned minor diameter basal surface 39 side of above-mentioned first protuberance 45 is connected with above-mentioned minor diameter basal surface 39.
This occasion, axially elongated in hub for vehicle wheel portion 31 of the development length of the first protuberance 45, the contact area between hub for vehicle wheel portion 31 and wheel body 32 increases.Further, since the axial end of the first protuberance 45 is connected with minor diameter basal surface 39, therefore, the torsional rigid of the first protuberance 45 improves.
It is also possible that on above-mentioned minor diameter basal surface 39, be provided with multiple 3rd protuberances 47 axially circumferentially spaced.
This occasion, in minor diameter basal surface 39 side, is engaged by the 3rd multiple protuberances 47, hub for vehicle wheel portion 31 and wheel body 32.Therefore, even if in minor diameter basal surface 39 side part, it is also possible to obtain the enough intensity for transmitting moment of torsion to wheel body 32 from hub for vehicle wheel portion 31.
It is also possible that on above-mentioned minor diameter basal surface 39, be provided with multiple 3rd protuberances 47 axially, at above-mentioned first protuberance 45 being connected with above-mentioned minor diameter basal surface 39, connect the axial end of above-mentioned 3rd protuberance 47 circumferentially spaced.
This occasion, owing to the end of the bearing of trend of the first protuberance 45 is connected with the 3rd protuberance 47 on minor diameter basal surface 39, therefore, the torsional rigid of the first protuberance 45 is higher.
It is also possible that the axial end face of above-mentioned major diameter basal surface 38 side in above-mentioned hub for vehicle wheel portion 31, it is provided with the housing recess 41 of the nut 42 that configuration is threadeded with above-mentioned axletree 20.
This occasion, because being used for configuring the housing recess 41 of nut 42, the material of the inboard portion of major diameter basal surface 38 is cut down.Therefore, it is possible to avoid increasing along with the volume in hub for vehicle wheel portion 31 and causing weight to increase, meanwhile, form hub for vehicle wheel portion 31 occasion passing through to cast, it is also possible to the generation of the shrinkage cavity that suppression causes because of the wall thickness increase in hub for vehicle wheel portion.
