An Example in Aluminum Casting
Brake Pedals for the Corvette Sports Car
?The Application — The Chevrolet Corvette is a world-class
sports car with outstanding road performance and unique styling.
In designing the Corvette, General Motors engineers had the
mandate to develop a vehicle design that communicated
unrivaled performance and style, while reducing weight for fuel
efficiency and acceleration.
?One component of the interior design is the brake pedal. The
brake pedal was originally designed as a welded steel assembly
that was heavy and required finish treatments for appearance.
?Component Description — The brake pedal in the
Corvette is designed as a offset bar approximately 15″ long with
an integral foot pad (with four slots on the face) on one end of
the pedal bar. The opposite end of the bar has a perpendicular
pivot cylinder for mounting and rotation. On the under side of the
bar there is a pocket in which the brake actuator rod sits with a
pivot pin
?Functionally, the brake pedal has to be a high strength
component (35 ksi tensile strength and 25 ksi yield strength) with
high ductility…
