Abstract:
1. A caliper attaching type electrical parking brake in a vehicle, comprising: a main housing that contains a motor and power assembly; an electronic parking brake control unit that controls driving of the vehicle and generates a control signal for implementing parking by receiving a signal of an operation button; the motor being driven by a control signal of the electronic parking brake control unit; the power assembly comprising: the axial force generating gear assembly generating power in an axial direction to presses to press a pad toward a wheel disk; a linear movement unit having a screw shaft configured to move forward, backward, and linearly by receiving the output torque generated by the sun gear; and a caliper installed to cover the wheel disk mounted on a wheel and implementing a parking braking state of the vehicle as a piston presses the pad with a shaft-direction pressing force applied by the screw shaft and a nut of the linear movement unit to restrict the wheel disk.
