Description

Plastic wheel hub

The utility model relates to traffic and transport field, relates generally to a kind of plastics vehicle wheel wheel.

For a long time, people use steel ring vehicle wheel wheel always, and solve attractive in appearance, antirust and wear-resisting problem by plating.But electroplating technology belongs to harmful work, and environmental pollution is serious; Of long duration, electrodeposited coating and spoke cap will come off; Spoke is compiled and transferred is a complicated job, compiles and transfers the improper wheel that will make to become " dragon "; The steel-tired wheel wheel need assemble, so labour intensity is big, complex manufacturing.

At the shortcoming of steel-tired wheel wheel, Europe and Japan have successively developed the Full-plastic bicycle wheel, have caused the attention of customer and manufacturer very soon.The beginning of the nineties, China has developed Tianjin the plastic bicycle wheel wheel of 8 spokes, but, caused the suspection of customer to plastics vehicle wheel wheel practicality because aspect problems such as rim fracture, spoke fracture have appearred in the problem of structure and material aspect after putting on market.9 spoke plastic bicycle wheel wheels (ZL932238904) of the great circle arc transition that Xingyun Jinsu Bike Co., Ltd., Tianjin released in recent years, solved the problem of rim load-bearing capacity difference, but it still only adopts 9 straight spokes, the tension of its spoke, compressive strength are still not really desirable, and (as being used in three-wheel vehicle) spoke still has the anxiety of fracture under big load.Have, the straight spoke of plastics vehicle wheel wheel does not have more than 9 as yet at present again, and the injection moulding cast gate of its mould is generally also below 9, so its injection mo(u)lding time is also longer.

The purpose of this utility model provides not easy fracture of a kind of rim, spoke, and the injection mo(u)lding time is short, intensity height, easy cleaning, novel plastic vehicle wheel wheel handsome in appearance.

The technical solution of the utility model is such:

A kind of plastics vehicle wheel wheel comprises rim, spoke, maincenter, axle sleeve, valve hole and reflective film perforation etc., and rim, spoke, maincenter, valve hole and reflective film perforation adopt the high-pressure injection Shooting Technique once to be injection molded into integral body, at the embedded ingot metal axle sleeve of maincenter.Spoke is 14 above rectangular distributions, and an end of spoke is connected with rim, and the other end is connected with maincenter.

When selecting for use spoke to be even number, per two spokes are crooked relatively respectively and link to each other formation

Shape; On spoke and rim inner edge, be equipped with the reinforced rib of projection, on rim, be provided with reflective film perforation.

The utility model compared with prior art has following advantage:

1, owing to increased the radical of spoke, at first make wheel wheel integral rigidity be enhanced, spoke and rim be easy fracture not all; Next is the number that can increase the injection mould cast gate, and cast gate can be designed into more than 14, therefore can shorten the molding time of product greatly;

2, after linking to each other, two adjacent spokes form

After the shape, the downward static pressure of the beaming roller that every spoke bore can decompose, so the tension of spoke, compressive strength increase;

3, adopt the engineering plastics single injection-molded, abandoned operations such as plating, assembling, spoke volume accent, alleviated labour intensity, reduced productive costs;

4, to mould Dai Gang, meet the bicycle trade developing direction, saved large quantities of steel, alleviated wheel wheel weight;

5, in engineering plastics, mixed ageing resistant and toughness material, withstanding corrosion, antiageing, not yielding;

6, handsome in appearance, bright in luster, make the wheel wheel that just can produce different colours with not homochromy mother.

7, production technology is simple, and surface finish is good, cleans easily.

Below in conjunction with drawings and Examples, further describe the utility model:

Embodiment 1:

A kind of plastics vehicle wheel wheel (as shown in Figure 1), comprise rim 1, spoke 2, maincenter 3, axle sleeve 4, valve hole 5 etc., rim 1, spoke 2, maincenter 3, valve hole 5 and reflective film perforation 6 adopt the ABS engineering plastics to make material, once be injection molded into integral structure with the high-pressure injection Shooting Technique, at maincenter 3 embedded ingot metal axle sleeves 4, the material of axle sleeve 4 can be used 46# unit's steel or other high strength alloy steels; Select 18 spoke rectangular distributions for use, so just can to shorten the time of formed product greatly, improve work efficiency increasing on the mould more than the cast gate number to 16, the spoke number increases the rigidity that can also improve the wheel wheel in addition; One end of spoke 2 is connected with rim 1 inner edge, its intersection is the arc transition about radius 30mm, and the inner edge that makes rim 1 forms the circular arc about 18 radius 30mm, adopt the form of this great circle arc inner edge, can enlarge the protection to rim 1 outer rim, when being subjected to external impacts, this structure can spread suffered external force to whole rim rapidly equably, thereby improved the rigidity of vehicle wheel wheel, made not easy fracture of rim; The other end of spoke 2 be connected with maincenter (as shown in Figure 2), the reinforced rib (as shown in Figure 4) that a projection is respectively arranged in the both sides of spoke 2, both attractive in appearanceization wheel wheels, increased the mechanical strength of spoke 2 again, the valve hole 5(that is provided with the column type hole on rim 1 is as shown in Figure 3), on the inner edge of rim 1, be provided with reflective film perforation 6.

Embodiment 2:

A kind of plastics vehicle wheel wheel (as shown in Figure 5), the title of its constituent elements is identical with embodiment 1 with used material; Also adopt 18 spokes, design goal is also identical with embodiment 1, and its difference is that 18 spokes are divided into 9 groups, and two spokes of every group are crooked relatively respectively and link to each other (as shown in Figure 6) formation

Shape, an end of spoke 2 is connected with the inner edge of rim 1, receives on the maincenter 3 after an end of the other end and adjacent spoke 2 crosses; This structure decomposes on two spokes of every group of wheel lower part the downward static pressure of beaming roller, be delivered to again on the rim 1 by two spokes, equally, when rim 1 is subjected to external impacts, its suffered external force part also is to be delivered on the maincenter 3 by every group of two spokes, thereby has increased tension, the compressive strength of spoke.The inner edge of rim 1 be designed to 18 circular-arc, can enlarge protection like this to rim 1 outer rim, make not easy fracture of rim 1, on spoke 2 and rim 1 inner edge, be equipped with the reinforced rib (as shown in Figure 8) of projection, not only attractive in appearance but also strengthened the mechanical strength of spoke 2 and rim 1; The valve hole 5(that is provided with the column type hole on rim 1 is as shown in Figure 7), on the inner edge of rim 1, be provided with reflective film perforation 6, can improve the safety factor of night running after the Reflector of packing into.

The utility model only needs each part dimension is done suitable adjustment, with regard to applicable each model men and women bicycle and three-wheel vehicle, behind equipped wire tape and the bicycle tube etc., can exchange with the steel-tired wheel wheel and use.China produces 3000 ten thousand of bicycles per year, and this utility model extensive market has high economic benefit and social benefit.
