Specific embodiment
The utility model describes a kind of lightweight child's bicycle wheel, has light-weight, and intensity can also carry
Vehicle body and children's weight.As shown in Figure 1, wheel includes wheel hub 1, spoke 2 and wheel rim 3 and tire 4 made of hard plastic,
Wheel hub 1, spoke 2 and wheel rim 3 are integrated injection molding, advantageously reduce the weight of wheel, while comparing after integrated injection molding
It is relatively high in other molding mode intensity.
As shown in Figure 1, spoke 2 is multiple plates, spoke 2 is evenly distributed on 1 outer peripheral surface of wheel hub and the sheet body of spoke 2
Perpendicular to the axis of wheel, be formed with the spacer holes 5 of multiple hollow outs between spoke 2 and the medial surface of wheel rim 3, spacer holes 5 it is each
A sharp corner is arranged to rounded corner, and spoke 2, wheel hub 1 and wheel rim 3 is avoided to there is the phenomenon that stress concentration after moulding.
2 loading end of spoke of plates is bigger, is conducive to the structural strength for promoting spoke 2, can preferably share application at wheel hub 1
Pressure.
As shown in Figure 1, end center of the spoke 2 close to 1 one end of wheel hub offers reinforced hole 21, reinforced hole 21 is from spoke 2
The intermediate position of spoke 2 is extended to close to one end of wheel hub 1, and the openings of sizes of reinforced hole 21 is from wheel hub 1 to the side of wheel rim 3
To gradually tapering up.After enabling to wheel hub 1 to contact with spoke 2 using reinforced hole 21, the power on wheel hub 1 can be applied more uniformly
Add on spoke 2, can significantly increase the intensity of spoke 2, promotes the bearing capacity of spoke 2.
As shown in Figure 1, the edge of reinforced hole 21 is provided with ribs 22, ribs 22 is outwardly protruded perpendicular to spoke 2.
Since spoke 2 is piece state, in the case where 2 stress of spoke is excessive, spoke 2 is bent along the axial deformation of wheel, on spoke 2
After ribs 22 is set, spoke 2 can be bent along wheel axial deformation and generate obstruction, that is, increase the intensity of spoke 2, promoted
Bearing capacity of the spoke 2 along wheel radial direction.
The spoke 2 of major part wheel is being arranged radially along wheel at present, and the spoke 2 positioned at wheel lower half portion is held in this way
The bearing capacity received is the largest, and with the rotation of wheel, the power that spoke 2 carries is also to be easy to produce fatigue in cyclically-varying
Damage.To solve the above problems, such spoke 2 is carrying as shown in Figure 1, spoke 2 dissipates setting along the tangential direction of wheel hub 1
When the power applied on wheel hub 1, the tangential direction due to spoke 2 along wheel hub 1 dissipates setting, bears the application of wheel hub 1 simultaneously
The quantity of the spoke 2 of gravity becomes more, and the power that every spoke 2 is born is opposite to become smaller, and can reduce 2 bearing capacity cyclically-varying of spoke
Peak value, improve service life.
As shown in Figure 1, the outer peripheral surface of wheel hub 1 is in drum type, i.e., the diameter at position is greater than wheel hub 1 among the outer peripheral surface of wheel hub 1
The diameter of outer peripheral surface at both ends, and the outer peripheral surface of wheel hub 1 is seamlessly transitted from intermediate position to both ends.In this way among wheel hub 1
Part thickness is larger, and because the power that wheel hub 1 carries is entirely applied to the position that wheel hub 1 is contacted with spoke 2, i.e. 1 appearance of wheel hub
The intermediate position in face, is capable of increasing the intensity of wheel hub 1, avoids bending deformation because 1 outer surface of wheel hub centre position intensity is insufficient.
As shown in Figure 1, offering axis hole 11 at the axle center of wheel hub 1, in normal situation, the both ends of axis hole 11 are nearby arranged
There is stepped hole, convenient for accommodating the bearing with locating axle.In the present embodiment, the circumferential surface of axis hole 11 projects radially inwards setting
There is lapping plate 12, lapping plate 12 is respectively positioned on inside axis hole 11 along the axial both ends of wheel hub 1.The bearing of wheel shaft then passes through overlap joint in this way
The both ends of plate 12 are positioned, while lapping plate 12 can also increase the intensity of wheel hub 1.
As shown in Figure 1, axially projecting on the outer peripheral surface of wheel hub 1 be provided with reinforcing rib 13, reinforcement can be also utilized in this way
The structural strength of muscle increase wheel hub.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
