ELECTRO ACTUATING WEDGE BRAKE APPARATUS OF VEHICLE AND CONTROLLING METHOD OF THE SAME

摘要

PURPOSE: An electro actuating wedge brake apparatus for a vehicle and a controlling method of the same are provided to improve the accurate of a braking operation by preventing the generation of non-linearity behavior in a wedge driving unit. CONSTITUTION: A wedge brake apparatus includes a driving wedge(110), a counter wedge(120), a wedge column(140), a nut bracket(160), a needle guide(170). One surface of the driving wedge is inclined. The counter wedge is opposite to the driving wedge. One surface of the counter wedge is inclined. The wedge column is installed to the driving wedge and pushes the driving wedge. The nut bracket is installed to the external surface of a ball screw(150) and transfers driving force to the wedge column. The ball screw is rotated by the motor. The need guide connects the wedge column and the nut bracket.
