Abstract:
1. A brake disk assembly comprising: a first disk having multiple first holes defined therethrough, a second disk having multiple second holes defined therethrough, first holes located corresponding to the second holes, a separation member located between the first and second disks, and a hollow area defined between the first and second disks, the hollow area communicating with an external space of the brake disk assembly through at least one gap between the first and second disks to form a heat convection path, wherein the first and second disks each have a friction face formed on an outside thereof, wherein multiple connectors are connected between the first and second disks and located corresponding to the first and second holes so as to define a cooling path penetrating through the first and second holes, wherein the connectors do not extend beyond the first and second friction faces; and wherein the connectors are formed on the first disk by way of pressing, the connectors are connected to first protrusions extending from the first disk and located around the first holes, a distal end of each connector is bent to form a bent portion which contacts the recessed area of the second disk.
