High reliability and Lightweight Pre-Mounting Brake System for Commercial Vehicles

摘要

The present invention relates to a brake assembly used for a commercial vehicle capable of increasing cooling performance. The brake assembly includes: a hub portion including a main portion for coupling a bearing housing to which a bearing is mounted so that an axle is inserted and rotated in the bearing housing and a flange portion formed on an outer periphery of the main portion to be coupled with the vehicle; and a disk portion including first and second disks, in which a plurality of ribs are formed between the first and second disks and the first and second disks and the ribs are integrally formed to be coupled with the hub portion. When the hub portion is coupled with the disk portion, coupling protrusions, formed between the first and second disks of the disk portion and protruding inward, are correspondingly coupled to a plurality of coupling grooves formed at the other end of the main portion having the flange portion. A spring gap is provided between the coupling groove and the coupling protrusion and a spring plate is fastened to the spring gap by a bolt.
