1. 轴箱橡胶垫 采用轴箱橡胶垫，改善了轮对的垂向振动效果及车轮踏面磨

1. 轴箱橡胶垫 采用轴箱橡胶垫时，轮轨横向力和轮轨间纵向力也比采用刚性承载鞍要小，有效地降低了对轨道的冲击，减少了钢轨的损坏。有利于提高转向架侧架等零部件的疲劳寿命。2. 侧架弹性下交叉支撑装置 交叉支撑装置还能有效的保持转向架的正位状态，减小车辆在直线和曲线运行时轮对与钢轨的冲角，改善曲线通过性能，减少轮轨磨耗。转K6转向架的两侧架之间通过摇枕、弹簧、斜楔连接，增加了新的连接方式，抗菱刚度显着增大。交叉支撑转向架的空、重车抗菱刚度比传统三大件式转向架大为提高。<br><br><br><br>

1. Axle box rubber pad<br>The axle box rubber pad is adopted to improve the vertical vibration effect of wheel set and the wear condition of wheel tread. When the axle box rubber pad is used, the transverse force between wheel and rail and the longitudinal force between wheel and rail are also smaller than that of rigid bearing saddle, which effectively reduces the impact on the track and reduces the damage of rail. It is beneficial to improve the fatigue life of bogie side frame and other parts.<br>2. Side frame elastic lower cross support device<br>The cross support device under the elastic side frame is adopted to improve the anti rhombic stiffness of the bogie, so as to improve the critical speed of hunting instability of the bogie and the stability of straight-line operation of the vehicle. The cross support device can also effectively maintain the normal position of the bogie, reduce the impact angle between the wheel pair and the rail when the vehicle is running in a straight line and curve, improve the curve passing performance and reduce the wheel rail wear.<br>The two side frames of zhuank6 bogie are connected by bolster, spring and wedge, which adds a new connection mode, and the anti rhombic stiffness increases significantly. The anti rhombic stiffness of empty and heavy vehicles of cross supported bogies is much higher than that of traditional three piece bogies.<br>

1. Rubber pad of axle box.The vertical vibration effect of wheelset and the wear condition of wheel tread are improved by using the rubber pad of axle box. When the rubber pad of axle box is used, the transverse force between wheel and rail and the longitudinal force between wheel and rail are also smaller than those of rigid bearing saddle, which effectively reduces the impact on track and reduces the damage of rail. It is beneficial to improve the fatigue life of bogie side frames and other parts.2. Elastic lower cross support device of side frame.Cross-bracing device under the elastic side frame is adopted to improve the anti-rhombic rigidity of the bogie, so as to improve the critical speed of meandering instability of the bogie and the stability of straight running of the vehicle. The cross support device can also effectively maintain the positive position of the bogie, reduce the impact angle between the wheelset and the rail when the vehicle runs in straight line and curve, improve the curve passing performance, and reduce the wheel-rail wear.The two side frames of ZhuanK6 bogie are connected by bolster, spring and wedge, which adds a new connection mode and significantly increases the anti-diamond stiffness. Compared with traditional three-piece bogies, the anti-diamond stiffness of empty and heavy trucks of cross-supported bogies is greatly improved.
