Krupp MaK公司开发了一种电传动内燃机车转向架的设计理论,适用于二轴和三轴转向架,速度范围高达160 km/h,不论从技术观点还是从经济观点看,此种设计构思均是先进的。提出的转向架最基本的特点是:用牵引杆作牵引连接;二级悬挂采用柔性钢质螺旋弹簧,结合模压橡胶组,特别考虑到在横向和转向架转动方向上有不同的弹簧比率;一级悬挂用柔性的钢质螺旋弹簧;轮对在横向面上由一级悬挂弹簧作导向,在纵向面上由装在橡胶套上的拉杆导向。转向架的构架是由焊接的空箱件组成的简单结构。
Krupp MaK has developed a design theory for electrically driven diesel locomotive bogies for biaxial and triaxial bogies at speeds up to 160 km / h, both technically and economically Is advanced. The most basic features of the proposed bogie are as follows: the traction rod is used for traction connection; the secondary suspension is made of a flexible steel coil spring combined with a molded rubber group, taking into account in particular that there are different spring ratios in the transverse direction and in the direction of rotation of the bogie; Grade suspension with a flexible steel coil spring; wheel pair in the horizontal plane by a suspension spring for the guide, in the longitudinal plane by the rubber sleeve installed on the rod guide. The frame of the bogie is a simple structure consisting of welded empty box parts.
