Definitions

• the present invention relates to a suspension mechanism for sliding doors enneajab ⁇ es, such as those used in rail cars and the like, doors that are locked in the body of the wagons, establishing external surface continuity in them, to in order to improve the conditions of aerodynamic penetration, and that for its opening they must be initially disengaged from said body, in order to be able to subsequently carry out the longitudinal sliding necessary for its opening.
• the object of the invention is to improve the conditions of engagement of the door in the body, for a better closure.
• one of the solutions used as most suitable for this type of doors is to use a horizontal and upper telescopic guide, from which the door is suspended, a guide that, in addition to being able to lengthen and shorten telescopically, is capable of moving in as a whole, when it is folded, in the frontal direction, in order to establish the maneuvering and disengagement of the same, of the corresponding housing of the car body.
• this frontal displacement is nothing more from the theoretical point of view, since in practice it is achieved by a pair of connecting rods, which at one end join the telescopic guide, while on the other they do fixed points of the car body.
• the car body housing must be designed, designed and sized to allow this biased movement of the doors, which implies a structural complexity in the closure significantly greater than if said doors carried out the engagement and disengagement maneuver with trajectories perfectly perpendicular to the general plane of your mouthpiece in the car body.
• the suspension mechanism proposed by the invention fully and satisfactorily resolves the above-mentioned problem, allowing, in accordance with the fundamental objective of said invention, that the sliding door performs its engagement and disengagement maneuvers with a perfectly perpendicular movement with respect to the plane general fitting of it.
• each of these guides is integral with a support , to which a pair of axes are in solidarity, which emerge perpendicularly from the extreme areas of said support and which are sliding with respect to the body of the car or element in question in the direction of its own axes, is say perfectly perpendicular to the closing plane.
• each of these axes is guided by a pair of sheaves, said axis also having a travel limit stop that obviously limits the movement of the door in the direction of disengagement thereof.
• each one of these axes incorporates, in correspondence with the support generatrix of one of the sheaves, a zipper, while the corresponding sheave incorporates a complementary teeth, leaving the respective sheaves of the different axes related to each other by means of a common axis that forces them to a synchronized movement, which is equivalent to a movement also synchronized of the corresponding axes through the respective zippers.
• this solution can be replaced by a torsion bar conveniently attached to the rear end and free of the shafts, which forces them, in a similar way, to a parallel and synchronized mobility.
• Figure 1. It shows a partial cross-sectional detail of a car, at the level of the suspension area of one of its doors, in which the structure of the suspension mechanism constituting the object of the present invention is observed.
• Figure 2. Shows a cross-sectional detail of the assembly represented in the previous figure, in accordance with the cut line AB of said figure.
• the mechanism of the invention focuses its characteristics on the fact that the telescopic guide module (3), opposed to the door fixing (1), is integral with a support (5), elongated in correspondence with the guide itself (3), which in turn are integral with their ends, two axes (6) that, fixed perpendicularly to the support (5), project horizontally towards the interior of the car ( 4), finishing off by its free end in two stops (7), which will be discussed next.
• These axes (6) intended to support the telescopic guide (3) and, through it, to the sliding door (1), are related to the carriage (4) or element in question, each of them , through a pair of rollers (8) and (9), with a grooved periphery corresponding to the curvature of the shaft (6), one located inferiorly, the one referenced with (8), in the vicinity of the support (5) while the other, the referenced with (9), it is located superiorly and in a considerably more remote situation, in order to absorb the stresses towards the axis (6), generated by the weight of the door (1).
• the supero-inner sheave (9) acts, in addition to guiding means for the axis (6), as an axial travel limit stop for said axis (6), when the stop (7) attached to the extremity falls on it free of said axle (6), butt that can nevertheless influence, to limit said movement, on any other fixed element of the structure of the car (4).
• the door (1) is capable of moving outwards, in a movement perfectly perpendicular to the general closing plane, thanks to the movement of its pair of axes (6) on the corresponding pairs of rollers (8) and (9), up to a limit situation defined by the stop (7) in which the telescopic guide (3) is located completely outside the body (4) of the car, remaining in conditions allowing the transverse movement of the door (1), for the corresponding opening maneuver, obviously establishing an antagonistic functionality for the closing maneuver.
• the door (1) or, if applicable, the pair of complementary doors (1) will be operated by any suitable pushing means, such as a pneumatic circuit that acts, for example, on the support (5), pushing or pulling it .
• a pneumatic circuit that acts, for example, on the support (5), pushing or pulling it .
• each axis (6) can be provided with a rack (10), for example on the upper generatrix of the sheave (9), said sheave (9) counting on a complementary teeth (11), and the rollers (9) corresponding to the different axes (6) of the door or doors (1), solidly joined together through a common axis (12), which forces them to a synchronized movement, so that it is impossible for any of these axes (6), it is offset in its longitudinal forward or backward movement with respect to the rest of the group.
