轉7和老轉8型轉向架是导框式鑄鋼側架轉向架,其下心盘与搖枕鑄成一体(新轉8已将下心盘和搖枕分开)。使用这两种轉向架的車辆,按其上心盘和車体的固結方法分为两种:用螺栓連結,用铆釘連結.前者在厂、段修时都分解检查,涂油組装;后者仅做外观检查,发現問題时才分解,一般則不分解。在后一种情况下,检修中調整車钩高度就比較困难,往往采用在軸箱頂部加圓铁垫板的方法調整。这是一个值得注意的問題。
Turn 7 and the old transfer type 8 bogie frame is guided steel frame bogie, the lower center of the heart and cast bolster (new transfer has been the next heart and the bolster separated from the bolster). Vehicles using these two bogies are divided into two types according to the method of consolidation of the upper center plate and the body of the vehicle: bolted and riveted, while the former is decomposed and inspected in the factory and section, and oiled and assembled; The latter only to do visual inspection, only to find the problem decomposition, generally do not decompose. In the latter case, it is more difficult to adjust the height of the coupler during maintenance, and it is often adjusted by adding a round iron plate on the top of the axle box. This is a noteworthy issue.
