COMPOUND SMART MATERIAL PUMP AND BRAKE SYSTEM USING THE SAME

摘要

The present invention relates to a compound intelligent material pump and a brake system using the same. According to the present invention, the compound intelligent material pump comprises: a first upper casing (120) comprising a first upper hollow space (110) therein, wherein the lower surface of the first upper hollow space (110) is opened; a first lower casing (160) attached to the first upper casing (120) and provided with a first lower hollow space (150) therein whose flat surface is opened, and a first inlet (130) and a first outlet (140) connected to the lower surface of the first lower hollow space (150); a first diaphragm (170) which is arranged between the first upper casing (120) and the first lower casing (160) to divide the first upper hollow space (110) and the first lower hollow space (150), and can be deformed; and a stackable intelligent material actuator assembly (100) arranged on an upper portion of the first diaphragm (170), and provided with a stackable intelligent material (180) to deform the first diaphragm (170) to reduce the volume of the first lower hollow space (150) when a voltage is applied. According to the present invention, deformation of a piezoelectric material according to a voltage change is used to continuously use braking power of a brake device by battery power even if an engine is stopped.
