The present invention relates to a driving device for a gravity racing vehicle, which performs non-powered driving by using gravity and recovery driving by using driving force, and comprises: a first relay gear which is rotated by being geared with a driving gear coupled to the driving shaft of a first motor; a middle shaft which is coaxially extended to be relatively rotatable with respect to the first relay gear; a counter gear which is mounted to be rotated after being concentrically linked with the first relay gear on the middle shaft; a linking hub which is rotated by being linked with the middle shaft while being concentrically coupled to the middle shaft; a sleeve which is mutually coupled or separated by the sliding movement between the linking hub and the counter gear; an advancing and retreating body which allows the sleeve to advance and retreat to deliver or block the rotating force of the first relay gear to or from the middle shaft; an advancing and retreating driving unit which drives the advancing and retreating body to advance and retreat; a driven shaft which delivers rotating power, applied by the rotation of the middle shaft, to a wheel; a first encoder which detects the number of revolutions of the middle shaft; and a control unit which calculates speed information from the number of revolutions of the first encoder to output the same by means of an output unit. Therefore, according to the driving device for a gravity racing vehicle, driving may be supported in the non-powered state by using gravity on an inclined road, such that the automatic returning of the vehicle by means of driving power may be supported regardless of the inclination on the car recovery route, while providing a simple structure.

    본 발명은 중력을 이용한 무동력 주행 및 동력을 이용한 회수 주행을 수행하는 중력 레이싱 차량용 구동 장치에 관한 것으로서, 제1모터의 구동축에 결합된 구동기어와 치합되어 회전되는 제1중계기어와, 제1중계기어에 대해 상대 회전가능하게 동축상으로 연장된 중간축과, 중간축에 동심상으로 제1중계기어와 연동되어 회전되게 장착된 카운터기어와, 중간축에 동심상으로 결합되며 중간축에 연동되어 회전되는 연동허브와, 연동허브와 카운터 기어 상호간을 슬라이딩 이동에 의해 상호 결합 또는 분리되는 슬리브와, 슬리브를 진퇴시켜 제1중계기어의 회전력을 중간축으로 전달 또는 차단하는 진퇴바디와, 진퇴바디를 진퇴되게 구동하는 진퇴 구동부와, 중간축의 회전에 의해 인가되는 회전동력을 바퀴로 전달하는 종동축과, 중간축의 회전수를 검출하는 제1엔코더와, 제1엔코더의 회전수로부터 속도정보를 산출하여 출력부를 통해 출력하는 제어부를 구비한다. 이러한 중력 레이싱 차량용 구동 장치에 의하면, 경사로를 중력에 의해 무동력 상태로 주행을 지원함과 아울러 회차경로에서는 경사와 관계없이 동력에 의해 자동회차를 지원하면서도 구조가 단순화되는 장점을 제공한다.
