railway transport; car building. SUBSTANCE: undercar module has box 1 with cover and guides carrying extensible frame 8 locked by stops. Front stops are formed by fastening units 13 of guide retractable cantilevers 5, 6. Module has storage battery insulators suspended from parallel beams of extensible frame. Each fastening unit is made in form of bracket connected to guide and/or box. Bracket is connected with cantilever by shackle with vertical and horizontal axles pressed to resilient stop of extensible frame at coupling of retractable cantilevers. One of them is connected with box flange. one of locking members is made on undercar suspension arranged at a maximum distance from shackle in outward direction. According to other design version, ends of beams are rigidly coupled at one level by cross members, and insulators are formed by seat and inserts with plate-type cross piece 38 on which storage battery is installed with slide fit. Center of mass of storage battery is located as close as possible to beam axes level. EFFECT: improved convenience and reduced labor input in servicing. 11 cl, 11 dwg
