FREIGHT CAR FOR BULK MATERIAL Russian patent published in 2000 - IPC

FIELD: railway transport; freight cars. SUBSTANCE: freight car 1 for bulk material has barn body 2 with bottom belt conveyor 4 and carrying frame 3 resting on running rear frame 9 provided with mechanisms 12 on ends. Discharge end 6 of bottom belt conveyor 4 is connected with transfer belt conveyor 8 arranged at angle relative to horizontal plane. Running gear frame 9 consists of first and second car frames 10 and 11, respectively, interconnected by coupler. Barn body 2 rests on both car frames through end thrust bearings 19, 20. One of thrust bearings is arranged on slides 21 to provide longitudinal displacement relative to car frame. Slides are made for displacement relative to car frame. Device 25 is installed between car frame and slides to prevent turning over and to provide movable coupling. Slides have several rollers 22 for rolling along car frame 10 or roller path found of car frame. Axes of rotation of rollers pass transversely relative to longitudinal axis of car. Flexible support members spaced transversely relative to longitudinal axis of car and coupling with carrying frame and car frame are installed between carrying frame 3 and car frame 11. Support members found in area between both thrust bearings are made in form of supporting and guiding cups of coil spring capable of moving relative to carrying frame or car frame in transverse direction. EFFECT: increased reliability of car. 6 cl, 2 dwg
