Wheel frame of the fiber composite material

摘要

A wheel frame of the fiber composite material includes multiple arched frame bars each including a foam body made out of a foam material and a fiber composite cover layer made out of a fiber composite material and wrapped about the foam body, the arched frame bars being joined together by means of connection surface portions of the fiber composite cover layers thereof to form a circular wheel frame, the connection surface portions of each two adjacent arched frame bars forming a support face to work as a support rib supporting the wheel frame. Thus, the fiber composite wheel frame has the characteristic of lightweight and will not easily break.

1. A wheel frame of a fiber composite material, comprising:
a plurality of arched frame bars, each of said arched frame bars comprising a foam body made of a foam material and a fiber composite cover layer made of the fiber composite material and wrapped about said foam body, said arched frame bars being joined together by the fiber composite cover layers thereof to form a circular wheel frame, connection surface portions of each two adjacent said arched frame bars forming a support face to work as a support rib supporting the wheel frame, wherein said foam body of each of said arched frame bars comprises at least one groove formed on the foam body; and the fiber composite cover layer of each of said arched frame bars is partially engaged into the at least one groove of the respective arched frame bar, wherein said fiber composite cover layer of each of said arched frame bar comprises an outer lateral portion for supporting a tire, an inner lateral portion disposed opposite to said outer lateral portion, and two of the connection surface portions opposing each other and two opposing side face portions respectively connected between said outer lateral portion and said inner lateral portion, each connection surface portion of one of said arched frame bars being connected to one connection surface portion of another one of said arched frame bars, and wherein each of said connection surface portions of each of said arched frame bars comprises the at least one groove.
