ELECTRIC BRAKE SYSTEM

摘要

An electric brake system is disclosed. The electric brake system comprises a hydraulic pressure supply device configured to generate hydraulic pressure using a hydraulic piston that is activated by means of an electrical signal output corresponding to a displacement of a brake pedal, wherein the hydraulic pressure supply device includes: a cylinder block; first and second hydraulic pistons movably accommodated inside the cylinder block and configured to perform a reciprocal movement by means of a rotational force of a motor; a first pressure chamber comparted by means of one side of the first hydraulic piston, one side of the second hydraulic piston, and the cylinder block, and configured to communicate with a first hydraulic circuit connected to one or more wheel cylinders; and a second pressure chamber comparted by means of the other side of the second hydraulic piston and the cylinder block, and configured to communicate with a second hydraulic circuit connected to the one or more wheel cylinders.
