Abstract
A splash shield for a vehicle wheel disc brake assembly is provided. Each wheel disc brake assembly includes a brake rotor having an inner brake surface and a splash shield. The splash shield includes a central attachment portion. Extending from the central attachment portion is a flange-shaped shield portion. The shield portion has an outer surface with a plurality of generally radially extending vanes formed on the outer surface of the shield portion, the vanes being positioned adjacent the inner brake surface of the brake rotor when the splash shield is mounted to the vehicle.
Claims26
A splash shield for a vehicle wheel disc brake assembly, each wheel disc brake assembly including a brake rotor having an inner brake surface, the splash shield comprising:
- a central disc portion;
- a flange-shaped shield portion extending radially outwardly from the central disc portion, the shield portion having an outer surface;
- a sidewall portion extending between the central disc portion and the shield portion the sidewall portion being substantially perpendicular to the shield portion;
- a plurality of vanes formed on the outer surface of the shield portion, the vanes extending from adjacent an outer edge of the shield portion inward toward the central disc portion;
- and
- wherein the splash shield remains stationary with respect to wheel rotation.
A method of cooling a disc brake rotor comprising:
- directing air along a plurality of vanes extending from a splash shield;
- directing the air from the vanes through an opening formed in a sidewall of the splash shield, the sidewall extending substantially perpendicular to the splash shield.
A system for cooling a disc brake rotor comprising:
- means for directing air along a radial span of the disc brake rotor to cool the disc brake rotor;
- and
- wherein the means for directing air include a shield having a substantially perpendicular sidewall portion;
- and
- wherein the air directing means remain stationary with respect to wheel rotation.
A splash shield for a vehicle wheel disc brake assembly, each wheel disc brake assembly including a brake rotor having an inner brake surface, the splash shield comprising:
- a central disc portion;
- a flange-shaped shield portion extending radially outwardly from the central disc portion, the shield portion having an outer surface;
- a sidewall portion extending between the central disc portion and the shield portion, the sidewall portion having a first and a second edge, the first edge being attached to the central disc portion and the second edge being attached to the shield portion;
- a plurality of vanes formed on the outer surface of the shield portion, the vanes extending from adjacent an outer edge of the shield portion inward toward the central disc portion;
- a plurality of vents formed in the sidewall portion of the splash shield;
- and
- a plurality of tabs attached to the sidewall portion, each tab being associated with one of the plurality of vents.
