FIELD: railway transport. ^ SUBSTANCE: invention relates to devices designed for damping vibration of locomotive body relative top bogie. Proposed torsional spring of locomotive has rod 1 with lever 2 hinge coupled with body 3 of locomotive 5, and bearing fixed support 4 and movable support 6. Movable support has hollow cylindrical shell 11 with rod of torsion being arranged in shell for axial and angular displacement. Disk 12 is secured on one of end faces of cylindrical shell. Said disk is provided with pair of spherical projections 13 engaging with curvilinear surfaces 14 of two retainers 15 installed on other disk 16 rigidly secured on said rod of torsion. ^ EFFECT: improved damping characteristics of torsional spring. ^ 6 dwg |
