The invention relates to an embedded butt-joint type axle box positioning device capable of actively adjusting longitudinal displacement, comprising an axle box body and an axle box end cover which are in butt joint with the two ends of an axle box connecting arm respectively, wherein an actuator used for active adjustment and positioning connection of longitudinal displacement between a wheel setand a bogie frame is installed in the axle box connecting arm, one end of the actuator is connected to the bogie frame through a rubber joint and connected with a rubber stack positioning part used for transverse positioning, and the other end of the actuator is connected to the axle box body through a rubber joint. Compared with the prior art, longitudinal positioning of the actuator and transverse positioning of the rubber stack are integrated; the axle box body, the axle box connecting arm and the axle box end cover are in butt joint in sequence, the actuator is installed in the axle box connecting arm, and longitudinal positioning and longitudinal displacement active adjustment are synchronously achieved through the actuator, therefore the structural layout of the active axle box positioning device can be greatly simplified, disassembly, assembly and maintenance are facilitated, and meanwhile good longitudinal positioning and transverse positioning can be synchronously achieved.
本发明涉及一种内嵌主动调整纵向位移的对接式轴箱定位装置,包括与轴箱连接臂两端分别对接的轴箱本体与轴箱端盖,其中,轴箱连接臂内安装有用于轮对和转向架构架间纵向位移主动调整及定位连接的作动器,作动器一端通过橡胶关节连接至转向架构架,并连接有用于横向定位的橡胶堆定位部,作动器另一端通过橡胶关节连接至轴箱本体。与现有技术相比,本发明通过集成作动器纵向定位与橡胶堆横向定位,采用轴箱本体、轴箱连接臂以及轴箱端盖依次对接的方式,并将作动器安装在轴箱连接臂内部,利用作动器同步实现纵向定位与纵向位移主动调整,能够大大简化主动轴箱定位装置的结构布局,有利于拆装维护,同时能够同步实现良好的纵向定位与横向定位。
