Document Type and Number:
Japanese Patent JP5255729
Kind Code:
B2
Abstract:
There is provided a carbon-ceramic brake disc assembly (200) including a carbon-ceramic brake disc (210) having a first axis hole (211) in the center thereof, and a plurality of first holes (212) around the first axis hole (211), a hat part (220) having a second axis hole (221) in the center thereof, and a plurality of second holes (222) around the second axis hole (221); and a connection unit (230) connecting the carbon-ceramic brake disc (210) and the hat part (220), including bushings (231), each of which includes a head (231a), a body (231b) connecting to the head, and serrations (231c) protruding the outer surface of the body (231b) along the length of the body (231b), with a threaded hole (231d) pierced through the head (231a) and body (231b), lengthwise, the body (231b) being inserted into the first hole (212) in the carbon-ceramic brake disc (210), and the serrations (231c) being penetrated into the internal surface of the second hole (222) in the hat part (220) when forced to be inserted into the second hole (222) in the hat part (220), and a bolt (232) being inserted into the threaded hole (231d) in the head (231a) and body (231b) of the bushing (231). According to the present invention, both configurations of the hat part (220) and the bushing (231) are made simple at low cost. And penetration of the serrations (231c) of the bushing (231) into the hole (222) in the hat part (220) permits a firm connection between the hat part (220) and the carbon-ceramic disc (210).
