The door suspension assembly comprises a ferromagnetic flat plate (2) horizontally attached to a support rail (1) intended to be attached to a door frame above a doorway or entrance portal. Two supporting blocks (7, 7') are provided having openings, in which cylindrical bearings with an axial hole are located in which a hollow tube (5) is introduced. Said supporting blocks (7, 7') are provided for supporting a door panel (12). Three connectors (3, 4, 6) are located in a fixed position relative to the flat plate (2). Said connectors support small portions of said hollow tube (5), which extends the same length as a required door travel. A magnet array (17) is supported by a plate (14) connected to said supporting blocks (7, 7'), wherein there is a small magnetic gap between the magnet array (17) and the flat plate (2), such that the magnet array (17) generates a magnetic force attracting the plate (2) and lifting thus the supporting blocks (7, 7') which support said door or door panel (12). The door suspension assembly comprises also a primary (15) of a motor attached to said supporting blocks (7, 7') and a secondary located in the interior of the hollow tube (5).
L'ensemble de suspension de porte comprend une plaque plane ferromagnétique (2) attachée horizontalement à un rail de support (1) destiné à être attaché à un cadre de porte au-dessus d'une entrée de porte ou d'un portail d'entrée. On prévoit deux blocs de support (7, 7') ayant des orifices, dans lesquels se trouvent des paliers cylindriques avec un trou axial, dans lequel est introduit un tube creux (5). Lesdits blocs de support (7, 7') sont destinés à appuyer un panneau de porte (12). Trois connecteurs (3, 4, 6) sont situés en position fixe par rapport à la plaque plane (2). Lesdits connecteurs accueillent de petites parties du tube creux (5), lequel a la même longueur qu'une course de porte requise. Une gamme d'aimants (17) prend appui sur une plaque (14) reliée aux blocs de support (7, 7'). Il y a un petit écart magnétique entre la gamme d'aimants (17) et le la plaque plane (2), de sorte que la gamme d'aimants (17) produise une force magnétique qui attire la plaque (2) et soulève les blocs de support (7, 7') qui accueillent la porte ou le panneau de porte (12). L'ensemble de suspension de porte comprend également un moteur primaire (15) attaché aux blocs de support (7, 7') et un moteur secondaire situé à l'intérieur du tube creux (5).
