The invention relates to a railway vehicle technology, in particular to a pull rod seat, a vehicle body and a railway vehicle. The pull rod seat comprises a base and a connecting seat, wherein the base is used for being fixedly connected with a vehicle body; the top of the connecting base is detachably connected to the bottom of the base, and the connecting base is provided with a connecting structure used for installing a bogie. The pull rod seat adopts a split structure; the pull rod seat has certain structural strength under a normal condition; by means of the structure, normal use can be guaranteed, when collision energy is large, the connecting base can be disengaged from the base, the situation that the collision energy is transmitted to the vehicle body through the pull rod base, and consequently the vehicle body deforms or is damaged is prevented, the vehicle body is protected, the safety of the whole vehicle is improved, and the later-period maintenance difficulty can be reduced.
本申请涉及轨道车辆技术,具体地,涉及一种拉杆座、车体及轨道车辆。该拉杆座包括基座和连接座,所述基座用于与车体固定连接;所述连接座的顶部可拆卸连接于所述基座的底部,且所述连接座设置有用于安装转向架的连接结构。该拉杆座采用分体结构,使拉杆座在正常情况下具有一定的结构强度,能够保证正常使用,并在碰撞能量较大时,连接座会从基座上脱离,防止碰撞能量通过拉杆座传递到车体而使车体产生变形或损坏,从而对车体进行保护,以提高整车的安全性且能够降低后期维修难度。
