FIELD: railway transport; vehicle brakes. ^ SUBSTANCE: proposed brake shoe of rail vehicle has off-axial conical working surface and cylindrical rear surface. Distance between axis of rotation of rear surface of shoe and working surface is greater than distance between axis of rotation of working surface and shoe working surface. ^ EFFECT: improved operating characteristic of shoe owing to reduction of possibility of cracking and breaking of edge parts of shoe in operation. ^ 2 dwg |
