The invention provides a lifting seat, a brake clamp assembly and a railway vehicle. The lifting seat comprises a base, a bogie connecting part and a clamp connecting part, wherein the base is provided with a first side and a second side which are oppositely arranged; the bogie connecting part extends and protrudes from the first side of the base and is used for being connected to the bogie; the clamp connecting part extends and protrudes in the direction away from the first side from the second side of the base and is used for being connected to a brake clamp unit; the bogie connecting part is provided with a through hole array and at least one key groove or key; and the bogie connecting part is fixed to a longitudinal framework of the bogie through the through hole array, and at least one key groove or key on the bogie connecting part is matched with a corresponding key or key groove on the longitudinal framework of the bogie. According to the design scheme, only a single part lifting seat in the brake clamp assembly is improved, and through the connecting mode of combining key groove matching and screw joint, the lifting seat is more compact in structure, high in connecting strength with the bogie, capable of bearing larger brake torque, high in installation stability of the brake clamp assembly and better in product reliability. In addition, an existing clamp product does not need to be changed, and the application range is wide.
本申请提供一种吊座、制动夹钳组件及轨道车辆。该吊座包括:基座,其具有相对设置的第一侧与第二侧;从基座的第一侧延伸凸出的转向架连接部,其用于连接至转向架;以及从基座的第二侧向远离第一侧方向延伸凸出的夹钳连接部,其用于连接至制动夹钳单元;其中,转向架连接部上具有通孔阵列及至少一条键槽或键;转向架连接部经由通孔阵列固定于转向架的纵向构架上,且转向架连接部上的至少一条键槽或键与转向架纵向构架上对应的键或键槽配合。此种设计方案,仅对制动夹钳组件中的单个零件吊座进行改进,通过键槽配合与螺接相结合的连接方式,吊座结构更紧凑,与转向架的连接强度高,能承受更大的制动扭矩,制动夹钳组件的安装稳定性高,产品可靠性更好,且无需改动现有夹钳产品,适用范围广。
