Abstract
Brake rotors for bicycles are described herein. An example brake rotor for a bicycle includes a carrier to be coupled to a hub of the bicycle. The brake rotor also includes a brake track having braking surfaces to be engaged by brake pads. The brake track is disposed radially outward of the carrier. The brake track has a first thickness and the carrier has a second thickness greater than the first thickness. The brake track is coupled to the carrier such that the brake track is axially movable relative to the carrier while being radially and circumferentially constrained relative to the carrier.
Claims17
A brake rotor for a bicycle, the brake rotor comprising:
- a carrier to be coupled to a hub of the bicycle, the carrier having an arm with an end portion, the end portion having a protrusion extending in a circumferential direction;
- and
- a brake track having braking surfaces to be engaged by brake pads, the brake rotor having a rotational axis defining a coordinate reference, the brake track disposed radially outward of the carrier, the brake track having an inner peripheral edge with a notch, the end portion of the arm disposed in the notch, the brake track being axially slidable on the end portion, the notch of the brake track at least partially defined by a lip that is disposed radially inward relative to the protrusion of the end portion to radially constrain the brake track relative to the carrier.
A brake rotor for a bicycle, the brake rotor comprising:
- a carrier to be coupled to a hub of the bicycle;
- a brake track having braking surfaces to be engaged by brake pads, the brake track disposed radially outward of the carrier, the brake track having a first thickness and the carrier having a second thickness greater than the first thickness, the brake rotor having a rotational axis defining a coordinate reference, the brake track coupled to the carrier such that the brake track is axially movable relative to the carrier while being radially and circumferentially constrained relative to the carrier;
- and
- a positioning portion coupled to the brake track, the positioning portion to dissipate heat from the brake track, wherein the carrier has an arm with an end portion, and wherein the positioning portion has a notch, the end portion disposed in the notch, the end portion to slide in the notch when the brake track moves axially relative to the carrier.
A brake rotor for a bicycle, the brake rotor comprising:
- a carrier to be coupled to a hub of the bicycle;
- a brake track having braking surfaces to be engaged by brake pads, the brake track disposed radially outward of the carrier, the brake track having a first thickness and the carrier having a second thickness greater than the first thickness, the brake rotor having a rotational axis defining a coordinate reference, the brake track coupled to the carrier such that the brake track is axially movable relative to the carrier while being radially and circumferentially constrained relative to the carrier;
- a pin extending through an opening formed in the brake rotor, the pin having a head disposed on a first side of the carrier;
- and
- a clip coupled to the pin and disposed on a second side of the carrier, the head and the pin overlap with a portion of the brake track in an axial direction.
A brake rotor for a bicycle, the brake rotor comprising:
- a carrier to be coupled to a hub of the bicycle;
- and
- a brake track having braking surfaces to be engaged by brake pads, the brake track disposed radially outward of the carrier, the brake track having a first thickness and the carrier having a second thickness greater than the first thickness, the brake rotor having a rotational axis defining a coordinate reference, the brake track coupled to the carrier such that the brake track is axially movable relative to the carrier while being radially and circumferentially constrained relative to the carrier, wherein:
- the carrier has an arm with an end portion, the end portion having a protrusion extending in a circumferential direction, and
- the brake track has a notch with a shape corresponding to the end portion, the end portion disposed in the notch, the end portion to slide in the notch when the brake track moves axially relative to the carrier.
