The present invention relates to a single drive axle for a motor-driven forklift, for transmitting the power of a motor to wheels provided on both left and right sides of a drive shaft. The single drive axle comprises: a differential device (300) provided in parallel with the shaft of a motor (100); a decelerating means (200) for decelerating the power of the motor (100) and transmitting the same to the differential device (300); the differential device (300) for separating the power received from the decelerating means (200) to both sides and transmitting the same; and one wheel adapter module (400) and the other wheel adapter module (500) coupled to both sides of the differential device (300), and transmitting the power separated by the differential device (300) to externally mounted wheels. A motor driving gear (120) directly connected to a rotating shaft (110) of the motor, and a reduction gear rotation shaft (210) parallel to the rotating shaft (110) of the motor, are provided. A first reduction gear (220) of the decelerating means (200), meshing with the motor driving gear (120), and a second reduction gear (230) coaxially coupled to the first reduction gear, are provided. A differential gear (340) formed to mesh with the second reduction gear (230), the motor driving gear (120), and a power transmission housing (330) formed to embed the decelerating means (200) and the differential gear (340) therein are formed. The power transmission housing (330) is formed to be separated into one power transmission housing (310) and the other power transmission housing (320). Therefore, the safety of the forklift can be increased.

    본 발명은 모터의 동력을 주행용 구동축 좌우 양측에 구비된 바퀴에 전달하기 위하여, 상기 모터(100)의 축과 평행하게 구비된 차동장치부(300)와, 상기 모터(100)의 동력을 감속시켜 상기 차동장치부(300)로 전달하는 감속수단(200)과, 상기 감속수단(200)으로부터 전달받은 동력을 양측으로 분리하고 전달하는 차동장치부(300)와, 상기 차동장치부(300)의 양측에 각각 결합되며 상기 차동장치부(300)에서 분리된 동력을 외부에 장착되는 바퀴에 전달하는 좌, 타측 휠 어댑터 모듈(Wheel adapter Module ; 400, 500)로 이루어진 전동식 지게차량의 싱글 드라이브 액슬에서, 상기 모터의 회전축(110)에 직결된 모터 구동기어(120)와, 상기 모터의 회전축(110)와 평행한 감속기어 회전축(210)을 구비하고, 상기 모터 구동기어(120)과 치합하는 감속수단(200)의 제1 감속기어(220)와, 상기 제1 감속기어와 동일한 축으로 결합된 제2 감속기어(230)를 구비하며, 상기 제2 감속기어(230)에 치합되도록 형성된 차동기어부(340)와, 상기 모터 구동기어(120)와, 감속수단(200)과 차동기어부(340)가 내장되도록 형성되는 동력전달하우징(330)과, 상기 동력전달하우징(330)은 일측 및 타측 동력전달 하우징(310, 320)으로 분리될 수 있도록 형성하는 것을 특징으로 하는 전동식 지게 차량의 싱글 드라이브 액슬.
