機場捷運電聯車轉向架製造簡述 Introduction to the Manufacturing of TIAA MRT EMU Bogie Apparatus
組裝完成之完整轉向架。

機場捷運電聯車轉向架是電聯車最重要的部件之一,它直接承載車體自重和載重,引導車輛沿鐵路軌道運行,確保車輛順利通過曲線,並具有減緩來自車輛運行時帶來震動和衝擊的作用,因此轉向架的設計也直接決定了電聯車的穩定性和乘坐的舒適性。
機場捷運轉向架係由轉向架框、承樑及各部相關裝置設備所組成,其中轉向架框係由左右側樑、前後端樑以及中央橫樑等電焊而成,承樑則由承樑本體以及左右承樑錨座組焊而成,焊接完成後須進行各焊道檢查,檢查合格後分別進行熱處理、機械加工以及噴漆等作業,接著進行轉向架目視及尺寸檢測作業,確認各項尺寸合格後即送往轉向架組裝工廠進行各相關裝置設備之組裝,將各相關設備(管件、車輪組、齒輪箱、聯軸器、牽引馬達、煞車組、集電器、保險絲盒、空氣彈簧及主懸吊等)組裝至轉向架框或承樑上,並將承樑與轉向架框相互結合,再進行最後塗裝工作,使其成為完整轉向架。
完整轉向架須進行目視及尺寸量測作業,檢查項目有轉向架框架基準面與軸箱基準面之間的距離、位置最低之零組件至軌面距離(齒輪組底部)、軸距量測、聯軸器齒輪端及馬達端之高度差、設備目視檢查(牽引馬達、輪緣潤滑器、程計、速度感應器)、檢查每個螺栓是否鎖緊並劃線標示、空壓管路及其扣件安裝是否鬆動、電線及電線固定件是否鬆動、塗裝(外觀、厚度)、功能測試(空氣洩漏、煞車單元功能、集電器)、各零件之序號檢查,確認各項檢查合格後才可送至車輛組裝廠與車體結合,進行電聯車後續組裝與測試作業。

The EMU bogie is a significant apparatus in the TIAA MRT System that supports the vehicle’s weight and its loading, guides the train to operate along the rail, ensures the train to pass curves and alleviates vibration and shock caused by train operation. In other words, the bogie design directly determines the stability and comfort of the EMU.
The components of the apparatus consisted of the bogie frame, bolsters and relevant devices. The bogie frame is made from welding the left and right side girders and the central beam together; the bolster is welded with the left and right bolster anchorages. After welding, the welded tracks have to be inspected then subjected to heat treatment, machining and painting operations. Then, the bogie will undergo visual and dimensional testing to confirm its size and sent to the bogie assembly factory to assemble related devices including pipe fittings, wheel sets, gear boxes, couplings, the traction motor, brake set, collector, fuse boxes, air springs, and the main suspension onto the bogie frame or bolster. After the bolster is combined with the bogie frame and with the final coating procedure, the bogie is finally completed.
The completed bogie needs to be subjected to visual and dimensional testing including inspecting the distance between the base level of the bogie frame and axel box, the distance between rail surface and the components with the lowest position (gear unit bottom), wheelbase measurement, height difference between the gear end and the motor side of the coupling, visual inspection of devices (traction motor, flange lubricator, odometer, speed sensor), checking whether each bolt is locked and labeled, whether compressed air piping and fastening installations are loosened, whether wire and cable fastenings are loosened, coating (appearance, thickness), functionality testing (air leakage, brake unit function, collector) and serial number verification of each apparatus. After passing the criteria, the apparatus will then be qualified to send to the vehicle assembly factory for assembly with the main body and proceed on with the subsequent assembly and testing operations.
