Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
embodiment 1
According to shown in Fig. 1 to Fig. 4, a kind of cycle wheel described in the present embodiment, the multiple spokes including flower-drum 5, wheel rim 1 and be connected between flower-drum and wheel rim, described wheel rim inner circumferential is connected with multiple connecting panel 11, each connecting panel is plugged with a straight pin 2, straight pin side radially forms two perforation of passing for two spokes, one end of spoke forms the positioning head 32 offseted with one end of boring a hole, and the positioning head of described two spokes is in the both sides of connecting panel.
Described wheel rim 1 passes through furling plate round machine bending forming by the aluminium alloy extrusions of strip, and the other parts of circumference residing for described connecting panel are in the shaping rear excision of wheel rim with expendable weight, and the connecting panel of final molding is trapezoidal.
Described wheel rim 1 also can adopt carbon fiber or magnesium alloy one-body molded.
Described flower-drum 5 two ends symmetrical molding has the multiple connection protuberances 51 be equally spaced along flower-drum circumference, each described connection protuberance forms two each sides relatively connecting protuberance in order to fixed orifice 511, two fixed orifices connecting described interior spoke and form spherical concave surface respectively.Be connected to the angle of formation 160 degree between two spokes on same connection protuberance on two fixed orifices.So both convenient to connect on protuberance two differences towards the processing of fixed orifice, be also beneficial to the installation of interior spoke, contribute to strengthening shock-absorbing performance simultaneously.
Spoke 4 and outer spoke 3 in described spoke is included and to be connected by threaded coaxial; One end of described outer spoke is positioning head 32, and the other end is male threaded joint 31; One end of described interior spoke is round platform positioning head 41, and the other end is the nut portion 43 be connected with male threaded joint; Interior spoke is arranged with the semisphere shock ring 6 of the plastic material be positioned between round platform positioning head and spherical concave surface.Described positioning head side forms the plane of orientation 321 coordinating with connecting panel and offset to stop outer spoke to rotate.After the perforation of described outer spoke through straight pin, positioning head is against one end of perforation, and plane of orientation 321 is fitted with connecting panel surface simultaneously; Distance between the plane of orientation being connected to the positioning head of two outer spokes on same straight pin just equals the thickness of connecting panel, namely outer like this spoke can not rotate, facilitate interior spoke mutually externally spoke screw, and in after having screwed, spoke, outer spoke are all not easy to produce and rotate, and not easily get loose.
The position that described interior spoke is adjacent with round platform positioning head forms the shock ring auxiliary section 42 that external diameter is greater than interior spoke external diameter.In shock ring auxiliary section external diameter more slightly ensures, spoke and flower-drum connection location have higher mechanical strength, not easily produce distortion, and the fitting surface of the thicker shock ring auxiliary section of external diameter and shock ring has larger area, makes shock ring not fragile, ensure damping effect.
Described nut portion forms a pair or two pairs of parallel facess near one end outer wall of round platform positioning head.Spoke in described parallel faces spanner easy to use rotates.
One end diameter that described round platform positioning head is connected with interior spoke is greater than the diameter of round platform positioning head outer end.One end end face that described round platform positioning head and interior spoke are connected is equal with shock ring surface size and fit completely, can ensure shock ring uniform force like this, and the spherical of shock ring fully coordinates with the spherical concave surface of fixed orifice one end bearing strength is increased; In addition, the outer end of round platform positioning head is less, when the relatively spherical concave surface of such shock ring produces relative rotation, the outer end of round platform positioning head can not produce with spherical concave surface to be touched, rubs, rub between spherical like this concave surface and the fitting surface of shock ring little, extend the service life of shock ring, ensure that the effect of damping.
As shown in Figure 5, be installed on flower-drum at interior spoke, and after being tightened with outer spoke, between interior spoke and fixed orifice, leave gap, when wheel produces vibrations, moment is delivered on shock ring along spoke, forms the angle a of 5-12 degree between interior spoke axis and fixed orifice axis.
The thickness of described connecting panel is 1.5-6.0 mm, and the best is 2.4-4.0mm; The external diameter 2.0-8.0 mm of described interior spoke, the best is 3.2mm; The external diameter 1.5-3.5mm of described outer spoke, the best is 1.6mm; The spherical radius 2.5-4.5mm of described shock ring, the best is 3.35mm.
Through experiment, for the wheel of 26 cun, the thickness of described connecting panel is 2.4-4.0mm; The external diameter of described interior spoke is 3.2mm; The external diameter of described outer spoke is 1.6mm; Wheel can be made when the spherical radius of described shock ring is 3.35mm to possess best mechanical strength and shock-absorbing performance.For the wheel of other size, each numerical value adjusts by experiment.
embodiment 2
A kind of bicycle wheel spoke described in the present embodiment and the connection structure of wheel rim, include wheel rim 1 and spoke, described wheel rim inner circumferential is connected with multiple connecting panel, each connecting panel is plugged with a straight pin 2, straight pin side radially forms two perforation of passing for two spokes, one end of spoke forms and the positioning head 32 coordinating and fix of boring a hole.Described positioning head side forms at least one plane of orientation 321 coordinating with connecting panel and offset to stop outer spoke to rotate.
In order to fixing outer spoke makes it not rotate, perforation one end inwall of described straight pin also can be processed into the shape matched with plane of orientation, or bores a hole and positioning head cooperation position is that polygonal structure also can.In a word, as long as positioning head and connecting panel or cooperation position of boring a hole are non-circular, the fixing of external spoke all can be realized.
embodiment 3
A kind of bicycle wheel spoke described in the present embodiment, includes spoke 4 and outer spoke 3 in being connected by threaded coaxial; One end of described outer spoke is positioning head 32, and the other end is male threaded joint 31; One end of described interior spoke is round platform positioning head 41, and the other end is the nut portion 43 be connected with male threaded joint; The side of described positioning head has one in order to coordinate the plane of orientation 321 of locating to stop outer spoke to rotate with wheel rim.
Although oneself is through illustrate and describing embodiment of the present utility model above, be understandable that, above-described embodiment is exemplary, can not be interpreted as restriction of the present utility model, those of ordinary skill in the art can change above-described embodiment when not departing from principle of the present utility model and aim, revising, replacing and modification in scope of the present utility model.
