Description
' ~2X482~
The invention relates to elastic self-carrying bel-lows, in particular to vehicles, formed with ribs mutually separated by spaces and connected with connecting means.
From the technical literature various kinds of bellows are known for confining the space between the bodies of two con-nected vehicles at least on three sides.
' Articulated busses used to be provided with bellows i sewn from a cloth coated with a flexible synthetic material, the outer contour of which follows the outline of the body of the articulated bus. The cut and sewn ribs do not maintain the shape of the bellows, so they are provided with an extra reinforcement along the stitching. A further disadvantageous feature of the solution is that the stresses arising in course of the drawing apart of the bellows cause a permanent deforma-tion in the metal reinforcements.
From the patent HU-PS 171 185 elastic bellows made of textile-elastomer are known. The essence of this solution lies in that at least at -the elemen-ts assuring the self-carrying of the bellows are formed of at least -two textile-layers with the elastomer layer lying inbetween. The proflle-width of the vertical ribs is preferably constant, while in dependence on the dimensions of the bellows, from the connection of the horizon-tal ribs towards the vertical symmetry-axis of the bellows the profile-wid-th continuously decreases. The ver-tical and hori-zontal ribs are interconnected by a circular arc with a pre-determined radius and the outer and/or outer edges can be provided with a reinforcement made of a profiled cord.
Another solu-tion has one, three or even more layers containing properly oriented elementary fibres with at least 60 of the elementary fibre~ being of the same orientation. With this solution the elementary fibres are embedded in rubber and . .
lZZ4826 the shearing forces are lower.
~ A common deficiency of the solutions mentioned above lies in their high labour costs, as only manual manufacturing is possible. The deficiencies also influence the useful life of the bellows and the aesthetic appearance thereof.
A further disadvantage lies in the fact that bellows ' are composed of single elements cut out of sheet material.
; Accordingly, considerable waste is produced, increasing produc-tional costs.
From Italian technical literature, extruded bellows made without a textile body are also known. ~'he ribs are mainly hollow and are interconnected by connecting means. The defic-iency of this solution appears in the srnall, scarcely twofold, extensibility, high produc-tion costs and the fact that owing to the large dimensions the bellows can be used only under special conditions.
An object of the invention is to alleviate the defic-iencies of the prior art, i.e. -to develop elastic self-carrying bellows, which can be produced in an easy manner at low cost, and have good extensibility. The ribs should be small-sized, made of cheap and basic materials, and the design should be simple and aesthetic.
The invention is based on -the recognition that by using synthetic materials, preferably polyurethane foam material as a basic ma-terial and by a more simple s-tructural design, the object set forth can be achieved.
According lo the present invention there is provided an elastic self-carrying bellow-body in particular for articu-lated wheeled vehicles for connecting one part of such vehicle to another part of that vehicle and permitting those vehicle parts to move with respect to each other, the bellow-body having an upper arch, a transverse axis, two side walls and a lower B
arch with the upper and lower arches being similar to each other and the two side walls being similar to each other, said bellow-body having a longitudinal axis and ends each of which is adap-, ted to be connected to a portion of a vehicle body to couple ; vehicle body portions together, characterized in that said bellow-body side walls and arches include a multiplicity of ribs which are spaced apart along the longitudinal axis of the hellow-body, each of said ribs having a thickness dimension, and ` interconnecting means connecting adjacent ribs of said multipli-city of ribs, said interconnecting means being monolithic with said adjacent ribs so that said bellow body is monolithic and having a thickness dimension less than said rib thickness dimen-sion whereby bending stresses arising from opening and closing of the bellow-body are principally -taken up by said intercon-necting means so the bellow-body is very expandable and con-tractable.
The majority of the bending stresses arising in course of opening and closing the ribs is taken up in the range where the adjacent ribs meet. In order to decrease the bending stres-ses caused by the considerable bending and as a consequence to prolonge useful life, in a preferred embodiment at least on one side the cross-section of the connecting means is confined by an arc. The theoretical geometric configurations characteristic for the arched parts of the connec-ting means having coinciding symmetry-points or are displaced in relation to each other.
In order to promote mechanization of production and to facilitate assembly, disassembly and exchange, in a preferrred embodiment at least at one place transversely to the ribs the bellows are divided and at the ends thereof an outermost rib is formed.
In a further p~eferred embodiment, in order to assure close connection with the vehicle body the bellow-bodies are lZZ4826 '~ assembled of at least two parts.
In another preferred embodiment, facilitating pro-duction, in the two outerrnost ribs a Bowden-cable is inserted.
The invention will now be described in more detail, by way of example only, with xeference to the accompanying draw-ings, in which:-Figure 1 shows a schematic side-view of the elastic self-carrying bellows according to the invention;
Figure 2 is a frontal view thereof;
Figure 3 is a section taken along line III-III;
Figure 4 is a section taken along line IV-IVi and Figure S is a section taken along the line V-V.
! In the drawings, the self-carrying elastic bellow-body 1 is formed with an upper arch 2, two side walls 3, and a lower arch 4, which are formed with the ribs 5. In the verti-cal symmetrical axis of the elastic self-carrying bellow-body 1 the ribs 5 are divided and are interconnected by means of -the connecting means 16. The ribs 5 are arranged with the spaces d and are elastically i.nterconnected with the connecting means 6, 20 i.e. they are formed of one piece. In general the thickness a of the ribs 5 is larger than the smallest thickness b of the connecting means 6.
The elastic self-carrying bellow-body 1 according to the invention is provided at both ends with an outermost rib 8, incorporating the synthetic pipe lS and the Bowden-cable 9 therein. The elastic self-carrying bellow-body 1 is fixed to f the connected body of the bus along the outermost ribs 8.
The thickness of the connecting means 6 is formed in the range between the outer curvature and the inner curvature, 30 where it has the smaller thickness b.
At the point o~ division the ribs 5 are interconnected by the connecting means 16, which is formed of the stiffening l.ZZ4826 bars 11 provided with the screws 12 co-operating with the clamp-~ ing plate 13. ~rhe stiffening bar 11 is inserted between the two i ribs 5 of the elastic self-carrying hellow-body 1. The screws 12 are welded onto the stiffening bars 11 and pass through the bore formed in the connecting means 6 of the two ribs 5, the flexible sheet 10 protecting against dust, and the clamping sheet 13. The screws 12 are fixed with nuts.
The connecting means 6 may have a cross-section, wherein on the outer and/or inner side it is formed with at least one arc of identical and/or different radius, while the part without the arc is straight. In case of too large dimen-sions, as is the case in the embodiment illustrated llere, the ribs are thinned in the corner-range 14. As a consequence, the stresses arising in course of the mo-tion in the corner-ranges 14 can be considerably reduced, whereby the useful life of the bel-lows according to the invention can be well prolonged.
The described plastic self-carrying bellow-body 1 can be produced in pieces symmetrically divided and perpendicularly to the ribs 5. In this case the single pieces are joined into one unit in a manner known in itself, e.g. by glueing. In such a manner production can be considerably Eacilitated.
In the case of divided elastic self-carrying bellow-bodies 1 division is preferably performed along the plane pass-ing through the ver-tical symrnetry axis and lying perpendicularly to the ribs 5 forming the arch 4. The divided parts are inter-connected by means of the connecting means 16 already mentioned.
The bellows are preferably divided along the plane running perpendicularly to the ribs 5 forming the arch 4 and passing through the vertical symmetry axis of the elastic self-carrying bellow-body 1, because the slightest motions arise just in said range. Accordin~ly, the load of the connecting device can be decreased and as a consequence, the useful life thereof ~224826 can be prolonged.
The elastic self-carrying bellow-body 1 was cast from foamed ~olyurethane, having a density of 0.9 g/cm3, and the hardness was about 95 Shore. Any other basic material may be suitable. The most essential requirement lies in the fact high limit values of fatigue, proper hardness assuring self-carrying, sufficient elasticity and a lightweight structure can be achieved.
The elastic self-carrying bellow-body 1 according to the invention is at least ten times more extensible than the prior art.
