Description

Device for articulated joint of boxes a vehicle on multi-element rails.

The invention relates to a device for the articulated joint of boxes of a vehicle on rails of elements multiple, that when traveling an irregular path allows both necessary horizontal deviation, as well as the movement of nodding between neighboring boxes, which however, especially prevents balances between them.

According to the state of the art, a multitude of articulated joints for articulated box hitch of a vehicle on multi-element rails. Unions articulated made as spheroidal joints absorb the longitudinal, transverse and vertical forces that appear between neighboring boxes during vehicle movement over  multi element rails.

The spheroidal joints are known, by example, in documents DE-AS 16 05 188, DE 42 27 181 A1, DE 43 05 614 A1 and DE 44 46 282 C1. According to document DE 43 05 614 A1 describes an articulated joint that is arranged between two parts of a vehicle. The articulated union presents a bearing that is held with its outer ring on a support support that stands out over the end of the first part of the vehicle. A support stand that stands out over the end of the second part of the vehicle receives in its end a joint elastomeric, which is jointly and severally connected with the inner ring of the bearing. The articulated joint made in this way makes possible to absorb the horizontal deviation by rolling that appears in curved displacements, while the angle of inclination that appears when going through a depression or going through a top is absorbed by the elastomeric joint. Additionally, balances that are absorbed in a limited amount are absorbed appear between the parts of the vehicle. However, to limit controlled balances, or to prevent them completely, it They use additional devices.

From document DE 44 46 282 C1 a known balancing limiter that limits the amplitude of balancing between neighboring boxes. To do this, in the upper area of the portal between two boxes are arranged two articulated bearings, being arranged a first articulated bearing in a console of the first box and a second articulated bearing essentially horizontally displaced laterally from us with respect to the first articulated bearing in a console of the second box. Between both joints acts a connecting rod connecting rod, whose amplitude is limited or dampened by means of springs compression.

From document US 5586506 A a known articulated housing for rail vehicles according to preamble of claim 1 of the present invention, which it allows both the necessary horizontal deviation, as well as the pitching movement between neighboring, coupled boxes. Thus, a spherical joint is used in each articulated housing in the ground area between the neighboring boxes, being planned in addition, in the vertical middle longitudinal plane of the housing articulated, a couple of joint joints of equal effect, for which the lower joint is arranged in the guide area and the upper joint in the roof area of the boxes

Since the vehicle actuator railway needs multiple elements to totally prevent vehicle balancing, state exposed devices Known in the art do not fit this purpose.

Therefore, the objective of the invention is provide a device for the articulated joint of the boxes of a vehicle on multi-element rails, which allows both the necessary horizontal displacements, as well as the pitching movements between neighboring boxes, however prevents the balances between them.

The task is solved according to the invention by the characteristics of the main claim. Also, enter the neighboring boxes of a vehicle on element rails multiple is planned in its vertical vertical longitudinal plane a joint couple. The lower joint is arranged in the floor area and the upper joint is arranged in the box roof area. The lower joint has an eye bearing, housed by a support bracket attached in solidarity with the box, and a bearing fork, housed by a support support joined in solidarity with a box located in front, being able to attach the bearing eye and the fork of bearing through a vertical hinge bolt. Eye of bearing is equipped with a spheroelastic bearing for compensate for pitching movements between neighboring boxes, and the bearing fork is equipped with an articulated bearing inclined to accommodate horizontal deviations between the neighboring boxes and for the alignment of the hinge bolts. The upper joint is made of equal action with respect to the lower joint in the coupling area. The support of upper joint support, which houses the rolling eye, can be guided longitudinally movable on a support bearing jointly and severally with the housing, and support bracket of the upper joint, which houses the fork of bearing, can be guided longitudinally movable in a bearing support jointly and severally with the housing located in front.

In the upper joint, according to the claim 2, means for displacement are provided synchronously in the opposite direction on the bearing supports of a shape that guarantees alignment of the vertical axes of the bolts of hinge in the lower and upper joint.

Other embodiments of the invention are indicated in claims 3 to 7.

The invention is described in detail in then by an exemplary embodiment with reference to the drawings. Sample:

Fig. 2 a longitudinal section through the upper articulation of the device according to the invention with shafts Longitudinal alignment of articulated elements corresponding.

Fig. 3 a longitudinal section through the lower joint of the device according to the invention with shafts longitudinal inclined relative to each other of the elements corresponding articles, as they originate when traveling a depression.

Fig. 4 a longitudinal section through the upper articulation of the device according to the invention with shafts longitudinal inclined relative to each other of the elements corresponding articles, as they originate when traveling a depression.

Fig. 5 a side view of the joint bottom and top of the device according to the invention in its couple-shaped arrangement with inclined longitudinal axes with respect to others of the corresponding articulated elements,  as they originate when going through a depression.

Fig. 6 a side view of the joint bottom and top of the device according to the invention in its couple-shaped arrangement with inclined longitudinal axes with respect to others of the corresponding articulated elements,  as they originate when crossing a top.

Both the lower joint 1, 2, as well as the superior are made of equal action in the area of coupling of the corresponding articulated elements, both that you can limit the description of this part of the device according to the invention to the lower joint 1.

Joint 1 has a rolling eye 3, which is housed by a support bracket 5, rigid, joined in solidarity in the passage area with box 4, which stands out on the end of the first box 4. The bearing eye 3 it has a vertical through hole 6 in which a spheroelastic bearing 7. The spheroelastic bearing 7 allows gimbal movements between boxes 4, 15 neighbors.

The bearing eye 3 is housed by a fork bearing 8, which is housed by a rigid support support 16, united in solidarity in the passage area with box 15, which protrudes over the end of the second box 15. The fork of bearing 8 also has a vertical through hole 9 that axially aligns with the through hole 6 of the bearing eye 3.

The bearing fork 8 is made in two parts, the upper part 10 being joined with part 11 lower of the bearing fork 8 by means of 12 detachable fixing, especially by screws. In the upper part 10 and in the lower part 11 of the fork of bearing 8 is arranged an inclined articulated bearing 13 which allows cardanic movements. The union between the eye of bearing 3 and the bearing fork 8 is realized by means of a hinge bolt 14 used vertically, which goes through of the spheroelastic bearing 7 and through the bearing articulated inclined 13 and there it is fixed with known means.

By articulation 1 both the horizontal deviation between boxes 4, 15 neighbors during the travel of a curve, as well as the pitching movement between these boxes 4, 15 when going through a depression or going through a top, or also an overlap of both deviations.

Unwanted balances between boxes 4, 15 neighbors are not prevented only by the lower joint 1, because mainly they are possible, according to the constructive type, gimbal or spherical deviations. To avoid rocking, it has the joint 2 in the upper area of the portal between the 4, 15 neighboring boxes. While the coupling area of the corresponding articulated elements of articulation 2 and that of the joint 1 are made of equal effect, both the eye of bearing 3, as well as the bearing fork 8 are fixed movable in the longitudinal direction at the end of box 4, 15 corresponding.

For this, the support bracket 5 is guided axially movable and torsionally secure on a support bearing 17, which in turn is fixed by screws in the end of the associated box 4. On the other hand, the support stand 16 is also axially movable and safe against torsion in a bearing support 18, the support being fixed bearing 18 at the end of case 14 also associated by screws.

On the one hand, a traction element and / or compression 19, not shown, arranged between the support bracket 5 and the bearing support 17, especially a spring of compression, and on the other hand, a tensile and / or compression element 19 arranged between the support support 16 and the support bearing 18, especially a compression spring, causes a placement of the upper joint 2 of the shape still by describe, that the vertical axes of rotation of the joint 1, 2 bottom and top line regardless of the path of the path.

When traveling a curve in the path, between 4, 15 neighboring boxes appear deviations around the axis common vertical 20, defined by hinge bolts 14 in the joint 1, 2 lower and upper. In this case, the distance vertical between the ends of boxes 4, 15 neighbors is equal over the total height, and with it, the distance of the joints 1, 2 of the ends of the boxes 4, 15.

When traveling through a depression along the way, enter the 4, 15 neighboring boxes a pitching movement is performed, it is that is, the distance of the ends of the boxes 4, 15, located in front, in the lower zone remains constant due to the planned articulation realization, while decreasing the distance from the ends of boxes 4, 15, located in front, in the upper zone This distance decrease is absorbed through of the movable guide of the support bracket 5, 16 on the supports of bearing 17, 18 associated, so that the support supports 5, 16 move in the bearing supports 17, 18 against the resistance of a compression spring. Traction elements and / or compression 19 placed between the support support 5, 16 and the bearing support 17, 18 cause during the movement of pitching the alignment of the vertical axis 20 remains in the lower joint 1.

In the same way the increase of the distance between the ends of boxes 4, 15 neighbors when crossing a top, while the support brackets 5, 16 are removed from the bearing supports 17, 18 against resistance of the element of tension and / or compression 19, also synchronizing in this been the tension and / or compression elements 19 to the path of displacement of both support brackets.

For the compact realization of the joints 1, 2 arranged in pairs, regardless of the layout of the path, that is, even if the deviation overlap horizontal boxes 4, 15 neighbors with pitching movements appearing at the same time, a vertical axis 20 is guaranteed joint joint 1, 2 lower and upper, and with this, it is possible a horizontal deviation, free of force of the boxes neighbors

The realization of the upper joint 2 prevents unwanted balancing between neighboring boxes 4, 15.

The spheroelastic bearing 7 fixed in the eye of bearing 3 allows, conditioned to the constructive type, gimbal or spherical movements between boxes 4, 15 neighbors and damping in the longitudinal direction of the vehicle oscillations of tensile compression appear. But especially, spheroelastic bearings 7 make it possible, in the previous arrangement over each other with nodding movements between boxes 4, 15 neighbors, the perpendicular positioning of the corresponding hinge bolts 14, resulting in possible horizontal deflection, free of force of the boxes 4, 15 neighbors also for movements in depression or on top.

In addition, the use of a spheroelastic bearing 7 by the elastic layer facilitates the mounting of the bolt hinge 14 lower and upper, because the tolerances through freedom of gimbal movement or spherical.

The means for synchronized scrolling, in the opposite direction of the support bracket 5, 16 on the supports Upper bearing 17, 18 can be provided in embodiments alternatives, not shown, of the invention by means of a scissor arrangement or through a telescopic arrangement, which are arranged between, on the one hand the support brackets 5, 16 upper, and on the other hand the bearing supports 17, 18 Associate superiors.

In addition, according to another embodiment not shown of the invention, between the support brackets 5, 16 or the brackets of associated bearing 17, 18 a device can be arranged damper to cushion the pitching movement between 4, 15 neighboring boxes.

In another embodiment not shown of the invention, the upper joint 2 can be combined with a anti-roll device
