Embodiment 1

[0028] A sheet type plastic wheel, its structure is as follows figure 1 , figure 2 shown. The web 2 of equal cross-section structure is used to connect the wheel hub 1 and the central shaft part 3, and the entire wheel and the metal insert 4 are integrally injection molded, and the material used for injection molding is continuous glass fiber reinforced polypropylene resin. The angles between the centerlines of the lengthwise direction of the adjacent webs 2 can be equal or unequal, preferably equal. In this embodiment, the angles between the adjacent webs 2 are 30 degrees to ensure that the wheels rotate Even by force. The middle surface of the web is perpendicular to the middle surface of the wheel to ensure the convenience of mold release and mold design. The plastic wheel structure obtained can be used as a driven wheel of a bicycle or an electric bicycle.

Embodiment 2

[0030] A kind of sheet type plastic wheel, its main structure is identical with embodiment 1, the sheet structure that adopts is as follows image 3 shown. According to the actual wheel structure, there is a large space for connecting the hub end, but the space for connecting the central shaft part is small. In order to ensure that the overall web is evenly and reasonably stressed, the width of the web connecting the central shaft part end can be increased, and the thickness of the web connecting the hub end can be increased. . In this example, the width of the hub end is 20mm, the width of the connecting shaft part is 10mm, and the thickness of the connecting shaft part is 1.5mm. The thickness of the connecting hub end is 3mm.

Embodiment 3

[0032] A kind of sheet type plastic wheel, its main structure is identical with embodiment 1, the sheet structure that adopts is as follows Figure 4 shown. According to the design aesthetics and stress requirements, the web can be opened with holes of a certain shape. In this example, the end 5 of the web connected to the central shaft part is separated due to the opening, and the end 6 of the web connected to the hub is connected as a whole, and the opening of the web is a trapezoidal structure. The webs are set with equal thickness. The cross-sectional areas of the webs in this design along the length direction are basically equal, and the forces on each section are basically equal, which is conducive to the full utilization of materials.

Abstract

The invention relates to a plastic wheel structure and application thereof. The plastic wheel structure is made of engineering plastics and comprises a hub, a plurality of spoke plates, a central axle component and a partially metal insert. The hub is manufactured by means of integral injection molding, the outer hub and the central axle component are connected with each other by the spoke plates, the spoke plates are distributed along the radial direction of a wheel and are peripherally arrayed in a plane of the wheel in an equal-angle or unequal-angle manner, and the middle surface of each spoke plate is perpendicular to the plane of the wheel. Compared with the prior art, the plastic wheel structure and the application have the advantages that the spoke plates replace spokes, and excellent characteristics of the spokes are inherited while the weight of the wheel can be greatly reduced as the wheel is made of the engineering plastics; the whole wheel is formed integrally, links for respectively manufacturing and assembling three components (a hub component, a spoke component and a face plate component) of the original wheel are omitted, and the productivity is greatly improved; the appearance of the wheel is high in design flexibility as the wheel is manufactured by means of injection molding.

Description

technical field [0001] The invention relates to a wheel, in particular to a plastic wheel structure capable of integral injection molding and its application. Background technique [0002] Most of the currently used bicycle wheel structures are metal spoke wheels. This type of wheel is actually a steel wire suspension structure. The steel wire is in a fully tensioned state in this structure, which can give full play to the performance of the material. After using high-strength steel wire, The number of wires can be reduced. When assembling the wheel, use the spoke steel wire to connect the central axis part (face plate) and the hub according to a certain arrangement rule, and apply a certain pre-tightening force to ensure the overall rigidity. [0003] The structure uses metal parts, and the wheels are heavy, which is not conducive to energy saving and emission reduction. Common spokes are all made of high-strength steel wires, which require additional production processes...
