<p>An electronic mechanical brake system is disclosed. According to an embodiment of the present invention, provided is an electronic mechanical brake system, which comprises: a base carrier where a pair of pad plates for pressurizing a disc are installed as being able to move forward and backward; a caliper housing which is supported by the base carrier in order to pressurize the pad plates; a pressurizing member which has a ball nut pressurizing the pad plate by converting rotary motion into straight line motion by being installed in the caliper housing and a ball screw combined with the ball nut; a force sensor which is installed in the ball nut and senses load generated by the operation of the ball nut; a motor for generating rotary force to operate the pressurizing member; and a decelerator which is connected to a rotary axis of the motor and delivers the driving force to the pressurizing member. The decelerator is formed to change the deceleration ratio according to the load sensed from the force sensor.</p> |
