The invention relates to a railway engineering vehicle which comprises a vehicle frame (2) and a ceiling (6), wherein a lower hanging type hydraulic drive device mounting frame is mounted on the lowerpart of the vehicle frame (2); a hanging connecting assembly (4) is mounted at the top of the lower hanging type hydraulic drive device mounting frame and connected to the vehicle frame (2) through afastener (3); a lower hanging type hydraulic drive device (1) is arranged in the lower hanging type hydraulic drive device mounting frame; and a heat dissipation device (5) is arranged at the upper part of the ceiling (6), and is connected to the ceiling (6) through a radiator damping support (29). The integrated type hydraulic drive device and the heat dissipation device are arranged below the frame and on the ceiling respectively, so that the overall layout of the vehicle is more compact, the overall gravity center of the vehicle is effectively reduced, the overall dynamic performance of the vehicle is further improved, the mounting space is compressed to the maximum extent, and meanwhile, the operation and living space in the vehicle body can be increased, and modularized mounting canbe realized.

    本发明涉及一种铁路工程车辆,包括车架(2)和顶棚(6),车架(2)下部安装有下挂式液力驱动装置安装框架,所述下挂式液力驱动装置安装框架顶部装有悬挂连接组件(4),悬挂连接组件(4)通过紧固件(3)与车架(2)相连接,所述下挂式液力驱动装置安装框架内装有下挂式液力驱动装置(1),顶棚(6)上部装有散热装置(5),散热装置(5)通过散热器减振支座(29)与顶棚(6)相连接。本发明通过在车架下和顶棚上分别设置集成式液力驱动装置及散热装置,使车辆总体布局更加紧凑,有效降低车辆整体重心,进一步提高车辆整体动力学性能,最大限度压缩安装空间,同时可增加车体内的作业及生活空间,可实现模块化安装。
