The present invention relates to a driving device for a rubber-tired lightweight electric railway and, more specifically, to a driving device for a rubber-tired lightweight electric railway which has a return spring with the same acting force in compression or stretching between a cart frame and a vehicle body accommodating passengers/cargo to prevent excessive rotary motions of a driving device when a rubber-tired lightweight electric railway vehicle runs on a curved section, alleviate horizontal impacts and vibration to prevent riding comfort degradation, and improve driving stability. The driving device for a rubber-tired lightweight electric railway comprises: a rotating frame installed on a cart frame; and a return spring wherein one side thereof is rotatably connected to and installed on the rotating frame, and the other side thereof is fixed and installed on a vehicle body to allow a rotary motion between the vehicle body and the cart frame.

    본 발명은 고무차륜형식 경량전철용 주행장치에 관한 것으로, 객/수화물을 수용하는 차체와 대차프레임 사이에 압축 또는 신장 시에 동일한 힘이 작용하는 리턴스프링을 구비하여 고무차륜형식 경량전철이 곡선구간 주행시에 주행장치의 과도한 회전운동을 방지하고, 좌우방향의 충격 또는 진동을 완화하여 승차감 저하를 방지하고, 주행안정성을 향상키실 수 있는 고무차륜형식 경량전철용 주행장치에 관한 것이다. 본 발명은 고무차륜형식 경량전철용 주행장치에 있어서, 대차프레임에 설치되는 선회프레임과, 일측은 상기 선회프레임과 회동가능하게 연결 설치되고, 타측은 차체에 고정 설치되어 차체와 대차프레임 간 회전운동이 이루어지도록 하는 리턴스프링을 포함하여 이루어지는 것을 특징으로 한다.
