The invention can be used to makeup high-speed passenger trains. The novelty consists in that in the proposed trailer car each non-motorized truck comprises two non-motorized wheel pairs, each of which comprises an axle, two wheels pressed on the axle and three brake disks mounted on the axle and located at equal distances from each other, while in the working part of each brake disc ventilation channels are provided which are formed by cooling fins, and in each end of the body next to a platform sacrificial zones are provided having reduced strength compared to the main part of the body, and the body is made in the form of an aluminum monocoque design, as bearing elements and elements connected with a body are provided aluminum profiles and aluminum sheets, a body floor divides the trailer car into manned and technical parts, the latter of which is designed to accommodate undercar equipment and is closed from the sides by an aerodynamic protective screen, and on a roof a conditioning system and a brake resistance are located. Technical result - increasing the speed limit due to simultaneous reduction of aerodynamic drag, reduction of car weight, possibility of more efficient allocation and placement of undercar equipment and also by improving the efficiency of perception and transmission of traction and braking forces. |
