The present invention relates to a single drive axle brake for an electric forklift vehicle, which aims to transfer the power of a motor to wheels formed on both sides of a drive axle, comprising: a differential apparatus unit (300) which divides and transfers the power received from the motor (100) to both sides. The differential apparatus unit (300) includes: a differential gear apparatus (340) which divides and delivers the power transferred from the motor to the wheels placed on both sides; and a brake apparatus (360) which constrains the differential gear apparatus (340). The differential gear apparatus (340) includes: a ring gear (crown wheel; 341) of the differential apparatus receiving the power of the motor; a differential gear case (347) engaged with the ring gear (341); a differential pinion (pinion gear) installed to rotate with the differential gear case (347) and to revolve around; and differential side gears (344, 345) placed in the differential gear case (347) engaged with the ring gear (crown wheel; 341) of the differential apparatus, which is engaged with the differential pinion gear. The brake apparatus (360) additionally includes: a main brake (380) which constrains and stops the differential gear case (347); and a sub brake (390) which stops the rotation of the power shaft (349). The present invention is able to improve the safety of a forklift.

    본 발명은 모터의 동력을 주행용 구동축 좌우 양측에 구비된 바퀴에 전달하기 위하여, 상기 모터(100)로부터 전달받은 동력을 양측으로 분리하고 전달하는 차동장치부(300)와, 상기 차동장치부(300)는 모터에서 전달되는 동력을 양측에 구비된 바퀴에 분배하여 전달하는 차동기어장치(340)와, 상기 차동기어장치(340)를 구속하는 브레이크 장치(360)이며, 상기 차동기어장치(340)는 모터의 동력을 전달받는 차동장치의 링 기어(crown wheel; 341)와, 상기 링 기어(341)에 결합되는 차동기어케이스(347)와, 상기 차동기어케이스(347)과 회전하며, 공전할 수 있도록 설치되는 차동 피니언(pinion gear)과, 상기 차동장치의 링 기어(crown wheel; 341)와 결합된 상기 차동기어케이스(347)의 내부에는 상기 차동 피니언(pinion gear)와 치합되는 차동 사이드 기어(Side Gear: 344, 345)가 구비되며, 상기 브레이크 장치(360)는 상기 차동기어케이스(347)을 구속하여 정지시키는 메인브레이크(380)와, 상기 동력축(349)의 회전을 정지시키는 서브브레이크(390)가 더 포함한다.
