Problems solved by technology

In this method, although there is a bonding process between the wheel frame and the spokes, the bonding force is still insufficient. In terms of the circumferential pressure resistance of the wheel frame (that is, the radial force from the circumference of the wheel frame to the center of the axis), there will be no pressure resistance. The absence of the gap relatively affects the impact resistance, twist resistance and rigidity of the entire composite material rim

Embodiment Construction

[0019] see Figure 1~6 shown. The composite wheel rim 1 of the embodiment of the present invention includes a ring-shaped hollow frame 10 and a plurality of spokes 20 . Wherein the outer peripheral surface of the wheel frame 10 is used for fixing tires, and a frame interior 11 is provided inside for accommodating brake calipers and brake discs and the like. The spokes 20 are located on one side of the frame interior 11, and corresponding to the axis position of the wheel frame 10, there is a central hole 21, and each of the spokes 20 extends radially from the periphery of the central hole 21, and the outer end It is connected to the inner side wall of the aforementioned wheel frame 10 to support the wheel frame 10 .

[0020] see Figure 4~6 As shown, the carbon fiber cloth of the stacked formed spoke 20 is mainly formed by stacking the first carbon fiber cloth 22 arranged at an angle of ± 45 degrees, through which the first carbon fiber cloth 22 is arranged at an angle of ±...

Abstract

A reinforced structure of a composite material rim, when spokes of the composite material rim are formed by stacking of carbon fiber cloth, a part of the carbon fiber cloth is arranged at a zero degree angle and extends to the wheel frame position from the spoke positions for stacking, thereby connecting the spokes and the wheel frame to improve the circumferential compressive resistance, impact resistance, torsion resistance and rigidity of the entire rim (or wheel frame).

Description

【Technical field】 [0001] The invention relates to a reinforced structure of a composite material wheel rim, and in particular, to a composite material wheel rim that can improve the circumferential pressure resistance, impact resistance, torsion resistance and rigidity of the wheel rim. 【Background technique】 [0002] Composite materials are mainly made of carbon fiber and other materials. Due to their strong and light texture, high temperature resistance, radiation protection, water resistance and corrosion resistance, they are widely used in blades of large wind turbines, racing cars, etc. , automobiles, motorcycles, bicycle bodies, and even large aircraft to reduce weight. This composite material is applied to vehicle rims as an example. The rim consists of two parts: a wheel frame and a wheel spoke. The conventional method of making a composite material wheel rim is to separately form the wheel frame and wheel spokes with composite materials, and then Combined to form a...
