DEVICE FOR TRANSMITTING CROSS HORIZONTAL FORCES FROM RAIL VEHICLE BODY TO BOGIES Russian patent published in 1995 - IPC

FIELD: railway transport. SUBSTANCE: unit of equalizing cross horizontal coupling of body 1 with bogies 2, 3 and 4 has longitudinal torsion shaft 5 installed on body in bearings 6, 7, 8. Fitted on ends of shaft 5 are vertical levers 10, 11, 12 pointed in opposite directions. Cross horizontal rods 16, 17, 18 hinge-couple ends of levers 10, 11, 12 with centers of bogies 2, 3, 4. Rods can be made either or flexible (extending-compressing) which is provided by fitting-in of flexible dissipative members. Rods 16, 17, 18 can be furnished with length adjusters to change cross position of body relative to bogie. Torsion shaft 5 can be either rigid or pliable to torsion; in the latter case rods 16, 17 and 18 can be rigid. Device can be mounted above bogies 2, 3, 4. One of rods 16, 17, 18 can be arranged under corresponding bogie, and other rod, above bogie. Distribution of forces between bogies is determined by relationship of arms of levers 10, 11, 12 being uniform if arms are equal. EFFECT: reduced weight of device transmitting horizontal forces from body to three bogies of vehicle, enhanced dynamic characteristics. 7 cl, 9 dwg
