本文系介紹机車車辆二軸轉向架三角形軸箱定位装置与彈性节点的改进情况。以往,这种轉向架的轮对是由轉动的三角形軸箱定位装置导向的,搖枕則按一般方式,由螺旋彈簧与搖枕吊杆支承,螺旋彈簧与摇枕吊杆均安装在轉向架构架侧梁的垂直凹槽內。搖枕吊杆改用榣枕拉杆后,因拉杆距車軸的中心平面太高,所以拉杆还須 This paper introduces the improvement of locating device and elastic node of triangular axle box for two axle bogie of locomotive and rolling stock. In the past, the wheelsets of such bogies were guided by a rotating triangular axle box positioning device. The bolster was normally supported by a coil spring and a bolster boom. Both the coil spring and the bolster boom were mounted on a steering wheel Vertical beams in the frame side rails. Bolster booms switch to the pillow after the pillow, because the rod from the axle center plane is too high, so the rod must
