FIELD: transport engineering; traction vehicles. ^ SUBSTANCE: proposed tractor cab has vertically installed tetrahedral support pillars 6, 7 between which front and rear windows and doors 10 with windows are arranged. Support pillars 6, 7 are intercoupled by ring-shaped flange 12 with rectangular slots enclosing support pillars 6, 7 from outer side and form sides. Front and rear support pillars 6, 7 are connected over ring-shaped flange by cross-bars to which girders 17 are attached provided with holes for fastening of roof. Arc-shaped beams are connected to ring-shaped flange 12 connecting front and rear support pillars 6, 7. Overwindow beams 21, 22 and window sill beams 23, 26 are connected to support pillars 6, 7 between which front and rear windows of cab cylindrical outline are arranged. Each door 10 is provided with spatial frame 29 consisting of straight vertical and arc-shaped cross tetrahedral bars 30, 31 to which transparent part of door in form of convex panel with cylindrical surface is glued from outside. Crescent-shaped sills 14 are connected under doors 10 with support pillars 6, 7. Angle-section backing are attached to crescent sills 14 of cab in flats of which holes are bade for fastening cab base. ^ EFFECT: improved comfort and safety of driver in tractor cab. ^ 2 cl, 8 dwg |
