机车采用CC轴式和BBB轴式在技术上各自的优缺点如下。优点:CC轴式简单,可由两台转向架代替三台转向架,车体重量容易分配在两个支点上;BBB轴式灵活,转向架轴距小,适于在多弯道的线路上高速行驶。缺点:C轴式的转向架全轴距大,与B刻式相比,通过曲线的性能差;采用BBB轴苏时,车体重量不易在三个支点上分配,较难采用复杂系统或铰接车体,粘着性能差。此外,在经济性方面,如果性能相同,无 Locomotives using CC-axis and BBB-axis technology in the respective advantages and disadvantages are as follows. Advantages: CC axis simple, can be replaced by two bogies three bogies, body weight easily assigned to the two fulcrum; BBB axis flexible, small bogie wheelbase, suitable for multi-curve lines on the high-speed Driving. Disadvantages: C-axis bogie full wheelbase, compared with the B engraved, through the curve of the poor performance; the use of BBB axle Su, body weight is not easy to distribute on the three fulcrum, it is difficult to use complex systems or hinged Body, poor adhesion. In addition, in terms of economy, if the performance is the same, nothing
