Method for Making a Composite Material Wheel Rim

摘要

A method for making the composite material wheel rim comprises the steps of: configuring a plurality of inner lining chunks individually to the desired position where the spokes are to be mounted so as to allow the inner lining chunks to be integrated with an inner annular portion of the wheel rim, next, integrating the formed inner annular portion with an outer annular portion of the wheel rim to form a semi-finished wheel rim, and then, creating the requested threaded holes for connecting the spokes in the inner lining chunks of the inner surface of the semi-finished wheel rim subject to the requested amount and angles of the spokes. By the prevent method, the semi-finished wheel rim allows to be drilled threaded holes subject to needs to fit different types of wheel hub units so as to increase the yield rate and reduce the inventory of the wheel rims.

1. A method for making the composite material wheel rim, comprising the steps of:
(a) in a first mold used for forming an inner annular portion of the wheel rim, placing a plurality of inner lining chunks individually to the desired position where each spoke is to be mounted, and then laminate-stacking carbon fiber cloth to enable the plurality of inner lining chunks to be encased in so as to process to form the inner annular portion of the wheel rim; (b) placing the formed inner annular portion in a second mold used for forming an outer annular portion of the wheel rim, stacking carbon fiber cloth onto the outer side of the inner annular portion after aligning the alignment point, and processing the combination of the inner annular portion and the outer annular portion so as to form a semi-finished wheel rim; (c) according to the spoke amount of the arranged wheel hub and the assembled angle of each spoke, drilling and tapping the requested holes in the inner lining chunks of the inner surface of the semi-finished wheel rim which is to be connected with the arranged wheel hub so as to form threaded holes, and thus the wheel rim is completely formed.
