FIELD: transport. ^ SUBSTANCE: in compliance with first version, freight car bogie comprises two side members and bogie bolster. The latter has opposite ends. Note that each end enters appropriate hole of said side member and is held suspended by spring set. Every side member has axle box opening on its every end to receive bearing adapter assembly. Proposed bogie comprises also two braking rail assemblies supported by said bolster and side members. Every assembly of braking rail comprises elongated main section, support section and deflecting section running between main an support sections. Two suspensions of braking rail with arm and base sections support braking rail assembly ends. Braking rail suspensions can be turned upside down so that support sections of braking head can be displaced laterally to allow adaption to various track patterns. In compliance with second version, one of said arm sections intersects base section, preferable at straight angle, while another arm section intersects base section at acute angle. Note that braking rail suspensions are turned relative to mounting holes on the end of every arm section. Note also that, in the latter case, track pattern between base sections of braking head varies. In compliance with third version, braking head support section is attached to one of the end sections of elongated main section of braking head, while braking rail suspensions can be turned so that two support sections of braking head are shifted laterally and spaced apart. Bogie bearing is arranged on bolster top surface. Note here that bogie bearing comprises disk-like insert made from malleable iron. ^ EFFECT: car bogie unification, adaptation to various track patterns. ^ 14 cl, 22 dwg |
