119型液力传动内燃机车的两台三轴转向架,出于制造和维修合理化方面的原因,结构设计完全是一样的(图1)。 1.构架转向架构架(图2)是带有箱形梁的轻型钢板焊接结构,它包括两根侧梁、两根端梁、两根辅助横梁以及中心销座的枕梁。由于该枕梁位于中间车轴齿轮箱上面,所以象桥一样向 The two three-axle bogies of the 119 Hydrodynamic Diesel Locomotive are exactly the same in structural design for reasons of rationalization of manufacture and maintenance (Figure 1). 1.
