Abstract

Device for driving the door of a vehicle, in particular the access door to the inside of a vehicle of the type dedicated to the transport of passengers, from a remote position, such as for example the driving position, said door being operable by longitudinal displacement in both directions, on suitable guides provided by the structure of the vehicle, between preset limits detected with limit switches or any other conventional sensor elements, characterized in that it comprises: - a generator group of movement involving a motor ( 1) direct current fed from the power source of the vehicle and associated with a reduction group that communicates the movement by means of an axis (2) ending in a gear wheel (3); - a movement transmission shaft (5) having a toothed wheel (4) capable of meshing with the toothed wheel (3) associated with the drive shaft (2), and that at the opposite end presents a second gear wheel (6) in the one that meshes the chain in charge of transforming the movement of turning into movement of movement to communicate to the door of the vehicle; - guiding wheels (7) of said chain, as well as other wheels (8) which, subject to the recovery of an associated spring (9), perform a tensioning action on the mentioned chain: - a support piece (10) in which assembly has been assembled, the matrix group being mounted on a guide that allows the relative movement between said drive group and the support piece depending on the position occupied by a cam (11) associated with the drive group by means of a rod ( 12), and this eccentric piece of talmode having two lugs (13, 13 "'') provided for subilization in an opening made in said support piece (10), so that depending on the lug (13, 13 "'') used as a stop element, the group will drive geared to the wheel (4) of transmission of movement to the shaft (5), or occupy a remote position, with both wheels (3, 4) separated and disengaged, allowing the release of the door and its ape manual opening, and arranging said eccentric (11) of an arm (14) by the opposite side to the lugs, provided with a means (15) for attachment, capable of being attached to a cable or other means of traction that at its end opposite is linked to an emergency lever, so that the activation of this emergency lever by any user determines the change of position of the cam (11) associated with the release of the door.
