Abstract
An easily mountable disc brake rotor assembly that is lightweight is provided. The bicycle disc brake rotor assembly includes a rotor and an adaptor and is mounted to the front hub of a bicycle. A caliper mounted to the bicycle's suspension fork grips the rotor. The rotor is a ring-shaped plate, which has brake surfaces that are gripped by the caliper. The adapter is mounted to the front hub and has a deformation that secures the rotor to the hub. External and internal splines on the adapter prevent the rotor from rotating and transmit a braking force exerted on the rotor to the hub, respectively.
Claims21
(canceled)
A bicycle disc brake rotor assembly comprising:
- a ring-shaped rotor having a pair of braking surfaces to be gripped by a caliper and
- an adapter including a securing mechanism configured to secure the rotor thereto, a rotation prevention mechanism formed between an outside surface of the adapter and the rotor to prevent rotation of the rotor relative to the adapters and an internal force transmission mechanism configured to transmit a braking force exerted on the rotor to an outer circumferential surface of a hub the internal force transmission mechanism includes a first internal thread configured to engage an external thread formed on the outer circumferential surface of the hub.
(canceled)
A bicycle disc brake rotor assembly comprising:
- a ring-shaped rotor having a pair of braking surfaces to be gripped by a caliper;
- and
- an adapter including a securing mechanism configured to secure the rotor thereto, a rotation prevention mechanism formed between an outside surface of the adapter and the rotor to prevent rotation of the rotor relative to the adapter, and an internal force transmission mechanism configured to transmit a braking force exerted on the rotor to an outer circumferential surface of a hub, the securing mechanism of the adapter includes crimping that deforms the adapter.
(canceled)
A bicycle disc brake rotor assembly comprising:
- a rotor having a pair of braking surfaces to be gripped by a caliper:
- and
- an adapter configured to be mounted to a bicycle hub, the adapter including a plurality of external bosses disposed at equal intervals in a circumferential direction of the adapter to non-rotatably secure the rotor to the adapter, and an internal force transmission mechanism configured to transmit a braking force exerted on the rotor to an outer circumferential surface of the bicycle hub, each of the bosses including a hole formed at a tip of each of the bosses with securing members secured to the holes to secure the rotor to the adapter.
