US 12,287,017 B2 · Collection apparatus for collecting particulate matter generated in brake system of transport facility

Abstract

The present invention relates to a collection apparatus for collecting particulate matter generated due to friction between a rotor and a brake pad in a brake system of a transport facility, the collection apparatus including a first collector configured to surround a portion of an outer side surface of the rotor, an upper collector configured to surround a portion of an outer peripheral surface of the rotor, and a second collector configured to surround a portion of an inner side surface of the rotor, wherein the first collector and the second collector are made of porous ceramic foam. According to the present invention, particulate matter generated due to friction between a rotor and a brake pad in a brake system of a transport facility can be efficiently collected, and by reducing the amount of particulate matter generated when braking a transport facility, air pollution can be prevented.
