Patent ID: 8646850

Claim:
A wheel rim with a brake rotor comprising: a wheel rim, the wheel rim having two retaining walls respectively and annularly formed on two lateral sides thereof, an annular groove annularly defined between the two retaining walls for adapting to retain a tire, the wheel rim having a plurality of support plates spacedly formed on one retaining wall and extending toward a center of the wheel rim to form a hub hole defined therein, the hub hole axially located at the center of the wheel rim for adapting to assemble with a wheel hub; and a brake rotor concentrically connected with the wheel rim and mounted with the other retaining wall of the wheel rim for adapting to be clamped by a disc brake, the brake rotor having a hook portion annularly formed thereon and extending from an outer periphery thereof for buckling with the corresponding retaining wall of the wheel rim, the brake rotor coveringly connected with a lateral surface of the corresponding retaining wall, the hook portion extending toward the annular groove and coveringly connected with an inner surface of the corresponding retaining wall, such that the brake rotor is mounted on the wheel rim; whereby when the brake rotor is clamped by the disc brake, the brake rotor is able to generate a relatively greater braking torque for providing an efficient braking.
