The invention discloses a locomotive underframe mounting base and a locomotive under-frame, which belong to the field of a locomotive body structure of a rail locomotive, and aim to solve the problems that the conventional locomotive underframe has the defects of complex structure and many processes in a production process. The locomotive underframe mounting base comprises a mounting base body formed by hanging bases and a support which are fixedly connected with each other; hanging holes for hanging a steering frame formed on the hanging bases; connection holes connected with a vertical damper of the steering frame are formed on the support; the hanging bases are provided with at least four first protruding parts extending vertically; each hanging hole is transversely formed on each first protruding part; the support is provided with at least two second protruding parts extending vertically; and each connection hole is vertically formed on each second protruding part. The locomotive underframe comprises the locomotive underframe mounting base. The locomotive underframe mounting base and the locomotive underframe provided by the invention can simply the locomotive body structure without influencing a structural effect, saves the process cost, and can meet the requirements on the lighten weight design of a locomotive.
Description
technical field [0001] The invention relates to the field of rail locomotive body structures, and relates to a locomotive chassis mounting seat and a locomotive chassis. Background technique [0002] In the design of the existing locomotive underframe, structures such as horizontal and vertical shock absorber seats and bogie hangers need to be set on the side beams of the underframe. Such a design makes the structure of the locomotive body complex, requires a wide variety of raw materials to be purchased, and requires a lot of manufacturing processes. Contents of the invention [0003] In order to overcome the shortcomings of the existing locomotive underframe with complex structure and many production processes, the present invention aims to provide a locomotive underframe mounting seat, which simplifies the structure of the locomotive body as much as possible without affecting the structural performance. The vertical shock absorber seat on the chassis of the locomotive ...
