By following detailed description, those skilled in the art will know these and other objects of the present invention, feature, aspect and advantage, and the preferred embodiments of the present invention have been introduced in this detailed description in conjunction with the accompanying drawings.
Description of drawings
Below with reference to accompanying drawing, this accompanying drawing forms an original disclosed part:
Fig. 1 is the amplification view of wheel rim of the front vehicle wheel of first embodiment of the invention;
Fig. 2 is the amplification view of wheel rim of the front vehicle wheel of second embodiment of the invention.
The specific embodiment
Introduce selection embodiment of the present invention below with reference to the accompanying drawings.Those skilled in the art can be known that by this specification sheets the explanation to the embodiment of the invention just is used for casehistory below, rather than in order to limit the present invention, because the present invention is determined by attached claim and their equivalent.
Fig. 1 has represented the amplification view of wheel rim 1 of the front vehicle wheel of first embodiment of the invention.Although only represented the wheel rim 1 of front vehicle wheel here, the present invention can be used for front vehicle wheel and rear wheel in the same manner.Wheel rim 1 is made of the substantially rigid material, for example well known to a person skilled in the art those materials.For example, wheel rim 1 can be made of the metallic material of any appropriate, for example aluminium, magnesium or titanium.
Each annular sidewall 2 forms annular stop surface 2b at its (side) exterior section 2a place, so as with common wheel rim brake engages, and circumferential rib 2c is formed at its (outside) free end, so that keep the tyre bead of tire in normal way.The interior section 2d of each annular sidewall 2 is connected with internal annular wall 3 respectively.The exterior section 2a of annular sidewall 2 has thickness t 1, and the interior section 2d of annular sidewall 2 has the thickness t 2 that reduces, and this thickness t 2 is less than t1, so that alleviate the weight of wheel rim 1.Strengthen regional 2e in the middle of having between the exterior section 2a of annular sidewall 2 and the interior section 2d, this centre regional 2e of enhancing has thickness t 3 in its midpoint.Below the 2b of annular stop surface, the regional 2e of middle enhancing has bottom cutting portion 2f, and this bottom cutting portion 2f preferably has female shapes.On the other hand, basic and bottom cutting portion 2f facing surfaces 2g has convex shape.In preferred embodiment shown in Figure 1, t1 is 1.7mm, and t2 is 0.6mm, and t3 is 1.2mm.Therefore, thickness t 3 is less than thickness t 1, and greater than thickness t 2.
When the inner tube of a tyre of tire (not shown) expanded, the exterior section 2a of annular sidewall 2 was subjected to being used to make exterior section 2a along perverted power F.This centre strengthens that regional 2e effectively prevents exterior section 2a because from the power F of the inner tube of a tyre and bending.
Preferably, outer annular wall 5 has core 5a that thickens and a pair of sidepiece part 5b with the thickness T 2 (being used for expendable weight) that reduces that thickness is T1.T2 is less than T1.In preferred embodiment shown in Figure 1, T1 is 1.0mm, and T2 is 0.8mm.Core 5a has more minor radius (comparing with sidepiece part 5b) with respect to center gear coil axis (not shown), and is connected with this sidepiece part 5b in a continuous manner.The thickness of outer annular wall 5 increases continuously towards core 5a from the side zone 5c of sidepiece part 5b.Therefore, between core 5a and sidepiece part 5b, there is not tangible boundary line.Core 5a and sidepiece part 5b form first continuous (gradually) curved surface 6a.The first curved surface 6a is a spill.And core 5a and sidepiece part 5b form second continuous (gradually) curved surface 6b.Second surface 6b is a convex.The first curved surface 6a is towards the bike tyre (not shown), and the second curved surface 6b is towards the cycle hub (not shown).The first and second curved surface 6a and 6b extend to exterior section 2a substantially.Because the first curved surface 6a is set to be used to receive the inner tube of a tyre, therefore most preferably be continuously (gradually) crooked concave surface, and above do not have precipitous step.On the other hand, second surface 6b can comprise step, so that form the core 5a that thickens.
Fig. 2 represented the wheel rim 1 of the front vehicle wheel of second embodiment of the invention ' amplification view.Although only represented here the wheel rim 1 of front vehicle wheel ', the present invention also can be used for front vehicle wheel and rear wheel in the same manner.Wheel rim 1 ' constitute by the substantially rigid material, those materials for example well known in the art.For example, wheel rim 1 ' can constitute, for example aluminium, magnesium or titanium by any suitable metal.
Wheel rim 1 ' major part identical with first embodiment, only additional annular reinforcing member 8 is installed in the outside of internal annular wall 3 and annular sidewall 2.Therefore, same reference numerals is used for same parts/part.
As shown in Figure 2, spoke construction opening 7a is arranged on the internal annular wall 3, is used to receive the spoke nipple (not shown).Additional reinforcing member 8 is formed from a resin, and comprise internal part 42 with a plurality of spoke opening 7b and with a pair of support member 41 of these internal part 42 bonded assemblys.Spoke opening 7b preferably is arranged to consistent with spoke construction opening 7a.Reinforcing member 8 is installed (preferably bonding) outside at internal annular wall 3 and annular sidewall 2 (preferably interior section 2d), like this, strengthen resin component and extend to another annular sidewall 2 (preferably interior section 2d) continuously through internal annular wall 3, so that cover the outer surface region of annular sidewall 2 (preferably interior section 2d) and the outer surface region around spoke construction opening 7a of internal annular wall 3 from one of annular sidewall 2 (preferably interior section 2d).Preferably, reinforcing member 8 extends to another bottom cutting portion 2f by inner (sidepiece) part 2d and internal annular wall 3 from a bottom cutting portion 2f.Reinforcing member 8 is received by bottom cutting portion 2f (recess that is formed by depth D), and like this, the transition portion 45 of surface 2b is steady, preferably smooth from support member 41 to annular stop.
When reinforcing member 8 be applied to wheel rim 1 ' metal master when partly going up, internal annular wall 3 increases at the thickness at spoke construction opening 7a place, the amount that increases is first amount that is formed by a plurality of (more) thick spoke installation portion 42a, internal annular wall 3 adjacent spoke mounting portion 42a between zone line in thickness increase, the amount of increase is second a small amount of that is formed by a plurality of (more) thin pars intermedia 42b (this pars intermedia 42b be arranged in adjacent spoke mounting portion 42a between).
Therefore, the variation in thickness of the internal part 42 of reinforcing member 8 is so that comprise a plurality of thicker spoke installation portion 42a and a plurality of thinner pars intermedia 42b.In Fig. 2, the part on dotted line is represented thinner pars intermedia 42b, and the part below dotted line is represented thicker spoke installation portion 42a.This thicker spoke installation portion 42a covers the spoke construction opening 7a spoke installation region on every side in the annular inner wall 3.This thinner pars intermedia 42b is arranged between the adjacent thicker spoke installation portion 42a.
Reinforcing member 8 is formed by a plurality of resin boards, these resin boards be fixed on annular sidewall 2, on the outer surface region below the 2b of annular stop surface and on the outer surface region of internal annular wall 3.Preferably, resin board is fibre-reinforced resin/plastic plate, and this plate comprises epoxy resin, and one or more impregnated carbon fiber layers are arranged.The resin board of fiber impregnation is welded together, so that form a plurality of integrated single-piece reinforcements.
Therefore, wheel rim 1 ' be the composite rim of making by metal and non-metallic material.Strengthen resin component 6 directly be bonded in wheel rim 1 ' metal parts on.
