Disclosed is a uni-body type heterogeneous material brake disk. In particular, the brake disk includes a friction part configured to be selectively in contact with a pad; and a hub joined with a bearing. More specifically, the friction part and the hub are made of heterogeneous materials through a uni-body type mold. To accomplish this, a connector connecting the friction part and the hub which are vertically spaced apart from each other is laterally spaced apart from the hub, and a bottom of the connector is connected with the hub. In doing so, an elevated platform is formed to prevent a casting from running over between the connector and the hub and an interface made of heterogeneous materials is formed in the connector.
A uni-body type heterogeneous material brake disk, comprising:
The uni-body type heterogeneous material brake disk of claim. 1, wherein material of the friction part is first injected to form the friction part and thereafter, material of the hub is injected to form the hub while forming the interface in the connector, on the same mold.
Dependencies are inferred from the claim text.
