FIELD: transport. ^ SUBSTANCE: proposed system comprises, at least, one door leaf that tightly bears against the outside sheathing in door opening in closed state. The other door leaf is outside the vehicle sheathing in open state to clear passage. At least, one door leaf is fitted in skids furnished with a lengthwise guide for, at least, one door leaf. The door opening top skids can be removed with the help of a mounting plate by moving them in direction perpendicular to the vehicle lengthwise axis. There is a drive for, at least, one door leaf and said skids for them to move in the aforesaid direction. The said drive consists of a motor and a chain or belt drive furnished with a guide brace with a pressure roller on its end. The aforesaid brace is arranged in skids parallel to the skids move-out direction. At least, one first and, at least, one second chain or belt drive guide rollers are arranged on both sides of the aforesaid brace. The proposed design allows moving out of skids with a torque. ^ EFFECT: moving out over, lateral shift of one door leaf occurs faster than moving out, but with smaller torque. ^ 16 cl, 7 dwg |
