Water cooled brake

摘要

A braking system includes at least one rotating disc and at least one brake disc. A brake disc wear plate is configured for retarding engagement with a rotating disc brake pad. Each brake disc has an annular coolant cavity associated with two inlet ports spaced apart 180° and two outlet ports spaced apart 180°. Each outlet port is spaced 90° from an adjacent inlet port. Each port leads to a respective radial channel. The channels are in open flow communication with each other. Inlet port coolant received into an inlet channel flows in both angular directions toward the outlet ports. Heated coolant gathered at an outlet channel is a mixture of coolant received from both inlet channels. Each inlet channel includes a stepped configuration to divert additional coolant to the outermost portion of the coolant cavity, which portion underlies the outermost (and hottest) portion of the wear plate.
