In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of carbon fiber automotive hub structure, carbon fiber wheel
Rim is connected by viscous glutinous substance with arc fiber-reinforced layer with carbon fiber spoke, effectively increases carbon fiber rim and carbon fiber wheel
Bonding strength between spoke, had both met the quick manufacture demand of spoke complex appearance, while also meeting automotive hub light weight
The requirement of change.
To achieve the goals above, the technical solution adopted in the utility model is as follows:
A kind of carbon fiber automotive hub structure, including carbon fiber rim and carbon fiber spoke, the carbon fiber rim have
One hard the first molded join domain, the carbon fiber spoke have the second join domain docked with the first join domain；
First join domain and the opposite side of the second join domain are coated with viscous glutinous substance, the carbon fiber rim and carbon fiber
Spoke is fixed together by viscous glutinous substance, and the periphery of the carbon fiber rim and carbon fiber spoke junction is coated with arc
Shape fiber-reinforced layer.
Further, the arc fiber-reinforced layer with a thickness of 0.8-2mm.
Further, arc length≤30mm of the arc fiber-reinforced layer.
Further, the wall thickness of the carbon fiber spoke is 6-20mm.
Further, the wall thickness of the carbon fiber rim is 3-10mm.
Further, the viscous glutinous substance is high-temp glue, is also possible to high temperature curable and glues other glutinous substances.
In a kind of embodiment, the carbon fiber rim is solid construction.
In another embodiment, the carbon fiber rim is hollow structure, and the carbon fiber rim is circumferentially arranged to be had
The tire slot to concave along diameter, the slot bottom of the tire slot is interior to be equipped with the cavity axially extended.
Wherein, the slot bottom of tire slot is divided into first part between tire slot and cavity and is located at the by the cavity
The second part of a part of opposite side, the thickness of the first part are greater than the thickness of second part.
Further, the first part with a thickness of 3-5mm, second part with a thickness of 0.5-1.5mm.
The utility model has the following beneficial effects: providing a kind of carbon fiber automotive hub structure, carbon fiber rim and carbon
Fiber spoke is connected by viscous glutinous substance with arc fiber-reinforced layer, is effectively increased between carbon fiber rim and carbon fiber spoke
Bonding strength, both met the quick manufacture demand of spoke complex appearance, while also meeting that automotive hub is light-weighted to be wanted
It asks.
