Abstract
The weight of a cast piece, such as a brake caliper casting, is reduced by inserting a core element of lower density than the density of the moulded or cast material into those areas of the cast piece which are not highly stressed when the cast piece is subjected to bending forces. Preferably, the core element is cast in place along with the casting material.
Claims6
A cast brake caliper having a U-shape with two legs interconnected by a bridge portion, said bridge portion being subjected to bending forces, said cast caliper comprising:
- a cast member having said U-shape;
- and
- a core element cast in said cast member in said bridge portion, said core element having a flat plate-like portion extending between and into each of said two legs completely encased on the top and bottom by said cast member and extending to and exposed in both outer edges of said bridge portion, said core element having a density lower than the density of said cast member.
