The invention discloses a vehicle head assembly and a rail transit vehicle, and relates to the technical field of rail transit vehicles. The vehicle head assembly comprises two functional assemblies distributed in the transverse direction of a bogie; each functional assembly comprises a sand box, a sanding arm located on the front side of the sand box in the longitudinal direction of the bogie and provided with a sanding nozzle at the bottom end, a sanding hose connected between the bottom of the sand box and the sanding nozzle, and a rim lubricating hose connected between the front side of the sand box and the sanding arm. In the transverse direction of the bogie, the sanding hose is located on the inner side of the rim lubricating hose; in the vertical direction of the bogie, the sanding hose is located below the rim lubricating hose. The sand spraying hose and the rim lubricating hose are reasonably arranged, the swing range of the sand spraying hose is located below the swing range of the rim lubricating hose, the swing ranges of the two hoses are staggered, and friction between the two hoses in the swing process of the bogie is avoided. By means of the arrangement mode, the risk that the hose is abraded and fails is reduced, and the running safety of the whole vehicle is effectively improved.

    本发明公开了一种车头总成及轨道交通车辆,涉及轨道交通车辆技术领域,车头总成包括两组沿转向架的横向分布的功能组件;每组功能组件包括砂箱、沿转向架的纵向位于砂箱前侧且底端设有撒砂喷嘴的撒砂臂、连接于砂箱的底部与撒砂喷嘴之间的撒砂软管及连接于砂箱的前侧与撒砂臂之间的轮缘润滑软管;沿转向架的横向,撒砂软管位于轮缘润滑软管的内侧;沿转向架的垂向,撒砂软管位于轮缘润滑软管的下方。通过合理布置撒砂软管和轮缘润滑软管,使撒砂软管的摆动范围位于轮缘润滑软管的摆动范围下方,两软管的摆动范围相互错开,避免两软管之间在转向架摆动过程中发生摩擦。这种布置方式降低了软管磨损失效的风险有效提高了整车的运行安全性。
