The invention provides a rubber wheel subway framework and bogie, the framework comprises a cross beam, four motor mounting seats are symmetrically arranged on the two sides of the cross beam in the longitudinal direction, and the motor mounting seats on the same side are arranged at intervals. The length of the framework is greatly shortened, the problems of insufficient rigidity and large machining deformation caused by a long-strip-shaped framework are solved, and the overall rigidity and manufacturability of the framework are improved.
本发明提供了一种胶轮地铁构架及转向架,该构架包括横梁,所述横梁纵向方向的两侧对称设置四个电机安装座,同一侧的所述电机安装座间隔设置。本发明大大缩短了构架的长度,解决了长条形构架带来的刚性不足和加工变形量大的问题,提高了构架的整体的刚性和工艺性。
