According to the present invention, a gear booster-type parking brake system comprises: a parking pedal (10) which generates a pedal stroke with a pedal arm (11) coupled to a pedal body (13); a planetary gear (20) which rotates a cable winding unit (15) boosting the pedal rotation force of the pedal arm (11) into gear rotation force to generate pulling force of a parking cable (30); an equalizer (40) which distributes the pulling force of the parking cable (30) as operation force; and a ball in ramp (BIR) caliper (50) which converts the operation force into parking force of the left and right vehicle wheels. The gear booster-type parking brake system uses the operation force boost of the pedal of the planetary gear (20) to generate a parking force proper for mid- to large-sized vehicles. According to the gear booster-type parking brake system, it is possible to satisfy the parking cable pulling amount needed for mid- to large-sized vehicles and configure a compact pedal at the same time.

    본 발명의 기어 배력식 파킹브레이크 시스템은 폐달 바디(13)에 결합된 폐달 암(11)으로 폐달 스트로크를 발생시키는 파킹 폐달(10), 폐달 암(11)의 폐달 회전력을 기어 회전력으로 배력하여 주차케이블(30)의 당김력을 발생시키는 케이블 권취부(15)를 회전시켜 주는 유성기어(20), 주차케이블(30)의 당김력을 조작력으로 분배하는 이퀄라이저(40), 조작력을 좌우 차륜의 파킹력으로 전환시키는 BIR 캘리퍼(Ball In Ramp Caliper)(50)로 구성됨으로써 유성기어(20)의 폐달 조작력 배력을 이용하여 중/대형차량에 적합한 파킹력 발생이 이루어지는 특징을 갖는다.
