산악트램의 급경사 급곡선 도로 주행을 위한 분할형 탄성 랙앤피니언 장치 개발

초록

A mountain tram is a type of light rail transit that runs on tracks embedded in roads characterized by steep gradients and sharp curves. In this study, a spur-type rack-and-pinion propulsion system was designed, manufactured, and tested specifically for mountain tram applications. To prevent interference between the rack and pinion caused by wheel wear or tight cornering, the gear profiles were optimized. Structural simulations were performed on the heat-treated steel components, confirming that they remain within allowable stress limits. To mitigate noise and vibration during gear engagement, rubber elastic elements were integrated into the pinion, which features a split-type design for simplified maintenance. Following prototype fabrication, structural integrity was verified through maximum and fatigue loading tests. Finally, a full-scale model bogie was tested on a purpose-built curved track, successfully confirming its operational safety and self-driving performance.
