Description

The The invention relates to a vehicle body for a carriage, the on or in the chassis body storable rollers in a rail or the like movable is and for attaching and / or Load a load over a coupling device is designed, wherein the carriage body a has larger side surface, arranged in a coupling receptacle and roller seats are. The invention further relates to a carriage with a carriage body and a trolley set.

Such carriages with carriage bodies are used for moving loads over a rail, for example in automobile production, in order to place seats as precisely as possible in a passenger compartment of a car to be equipped, wherein the vehicle with the load attached can be moved into the interior of the passenger compartment via a crane rail. Due to the different types of load and their insertion into the passenger compartment is often a complex and complex system with different carriages with different rigid and / or movable coupling receptacles necessary. Frequently, the openings and spaces through which or in which the loads are moved to their insertion, very limited, so that a stable, at the same time small-sized version of the trolley and in particular the carriage body is required. In the DE 94 02 896 U1 For example, a trolley is described in the form of a trolley, which is constructed quite expensive and is not universally applicable.

Of the The invention is therefore based on the object to provide a carriage body, which is easier and less expensive to produce and the universal can be used.

The Asked object is inventively achieved in that a first coupling receptacle and a second coupling receptacle are provided and that the first coupling receptacle first roller receptacles and the second coupling receptacle associated with second roller seats are each arranged in an edge region of the larger side surface are, with the respective coupling receptacle spaced from her associated caster recordings is arranged. This can the carriage body universally, for example, with different coupling receptacle sizes and / or -Specified, which, when used in a trolley several forms of load bearing are possible.

Preferably are the first coupling receptacle in a first edge region of the larger side surfaces and arranged the second coupling receptacle in a second edge region of the larger side surfaces. This can also be provided that the roller seats arranged in the edge region of the larger side surfaces are the edge of the area assigned to each coupling receptacle opposite. Thus, coupling receptacle and associated caster receptacles each provided in different border areas, so that both Types of recordings are more freely and easily accessible from the outside, and thus in particular the load unhindered or attached can be charged. It can be provided that the two coupling shots in adjoining border areas and their respective ones Caster shots also arranged in adjacent edge areas are. Here you can in a rectangular construction of the larger side surface the the coupling receptacles having edge abut each other at right angles, while the Border areas with the associated Crash rollers diagonally opposite each other at right angles. that is, in the rectangular structure can two converging sides or edge areas at least one each Coupling recording, while to each opposite lying side or edge regions arranged the associated roller seats are. Used in a rail system, must be to use change from one coupling receptacle to the other the carriage body or the carriage only rotated by 90 ° become. Furthermore, the roller seat, which is arranged in the area, in which the colliding ones Edge areas overlap with the roller seats, so positioned be assigned to both coupling recordings and thus used as a first and as a second caster recording can be.

In another embodiment can the larger side surface one triangular basic shape with preferably two equal, shorter sides and a longer one Side, wherein in the edge region with respect to the longer side preferably the Roller seats as first and second roller seats and the first coupling receptacle in the edge area one and the second Coupling recording in the edge region of the other shorter side can be provided. to preferably uniform force absorption The two coupling shots should be arranged as close together as possible be. Instead of the two shorter ones Pages can also be a different page history, for example, in one convex arc or a trapezoidal shape, be provided.

With regard to a preferably symmetrical load bearing and to simplify the structure, it is proposed that the first edge region is arranged opposite to the second edge region. Thus, also the coupling shots and associated caster receptacles may be arranged opposite one another such that the first coupling receptacle and the second caster receptacles are arranged in an edge region and the second coupling receptacle and the first caster receptacles are disposed in the edge region lying opposite this. Thus, the coupling receptacles and caster receptacles can be arranged mirror-symmetrically in relation to each other in the carriage body, wherein a line connecting both coupling receptacles forms the mirror axis of symmetry. In this way, a completely symmetrical structure can be achieved, which in turn allows a symmetrical load suspension or load and also further simplifies the production of the car body further. In this case, the first coupling receptacle for attaching a load and, preferably, at the same time, the second coupling receptacle for loading a load can be used even when using, for example, the first roller mounts.

It can at least two roller seats as first roller seats be provided. these can approximately in a row along be arranged of the edge region, wherein the outer roller seats to a small amount further from the second narrow side surface than the middle roller take-up are removed. As below yet to explain is, the two roles in a the roles essentially enclosing rail profile run, with the rollers on a first inner tread and on one of the tread opposite second tread support with play, so that the rollers are safe to move perpendicular to the direction of travel guided in the running rail are. The amount corresponds, plus a purposefully provided Game, the difference of rail height and track height.

Prefers however, each coupling receptacle is associated with four caster receptacles, which are preferably arranged in a row and in a preferred symmetrical arrangement arranged with them in one edge portion Flank coupling attachment symmetrically. For this purpose are preferred the two middle rollers by the small amount closer to one towards the larger side surface subsequent side surface arranged in a plate-like design of the carriage body as Narrow side is formed. Due to the paired arrangement of the roller seats, thanks derer in installation position two rollers on the two running surfaces of the Can attack rail results in a further stabilization of the trolley in his Driving behavior in the track rail.

In a particularly preferred embodiment of the carriage body can the first coupling receptacle rigid and the second coupling receptacle be designed to be movable. This will make the uses extended as the carriage body thus universal for different coupling means or attachment and / or Auflastarten be used can. A rigid coupling receptacle can be, for example, a crane hook, an opening to the hanging a load or the like, wherein the coupling receptacle rigid with the carriage body connected is. A movable coupling mount allows a change the relative position of the attached Load to the truck body and thus a swinging of the load into a position in which the moments of force are minimized to the coupling recording. This can further, for example for accurately positioning a load when inserted into a passenger compartment a car, manual corrections are performed.

Prefers the first coupling receptacle is a fork receptacle with a receiving slot for Introduce a coupling member for coupling the load include. The second Coupling receptacle can be a joint mount with one towards the larger side face open Interior for one Joint or a joint body include. Both forms are comparatively simple, stable and force symmetric versions, which can be realized constructively simple, as below shown in detail.

Prefers will continue with a plate-like design of the carriage body with two opposite ones larger side surfaces, where the coupling receptacles, i. the interior and the receiving slot, limited by both larger side surfaces become. Hereby, a simple and inexpensive construction is proposed. Especially the opposite larger side surfaces can also preferably have convex outwardly curved side surfaces, so that in cross-section a preferably lenticular structure with a reinforced cross-section can arise in the middle. This can be with an arrangement of coupling reception be cheap in the middle of the edge area, because here are the biggest forces Lastaufbringung can occur.

For simple and symmetrical force application will further suggest that the receiving slot is introduced into a narrow side adjacent to the first edge region. In order to simplify the structure further or material-saving and thus slimmer and easier to design and in particular to adapt the trolley body to usual, described in more detail below rails with a rail slot, the trolley body with respect to its first edge region with the first coupling receptacle a thicker cross-section with respect to its second edge region. Thus, furthermore, the cross sections are the Er Requirement of the respective coupling recording or coupling adapted.

Preferably have the larger side surfaces at least a support roll receptacle for support rollers for lateral support of the trolley in the rail or the like. According to the state of technology Trolley be arranged in a rail in which the carriage body in Installation position of the used for use roller seats the coupling coupling used to a section laterally on a rail element, for example through a guide slot the rail, passed becomes. In the method with an attached load, the carriage undesirable strike on the rail element and / or possibly on this over a distance grind, causing the attached undesirable can vibrate. For a calmer run of the vehicle to enable and to minimize the kinetic energy losses of the vehicle are the support rollers provided, which are arranged in the installed position in height of the rail element are and expediently can be unrolled in the direction of travel of the trolley.

Preferably the support roller receptacle are spaced apart to the first and second roller seats in the second edge area arranged. This is a preferred embodiment, for example a use of the trolley in a rail with a slot, the in-mounting position under the use of incoming caster shots or rollers and over which is arranged to use coming coupling receptacle. In this case, the slot width is preferably larger by a small amount than the roller diameter or, when using at least one Roller on a larger side surface, between the utmost to a respective slot bank facing areas of the treads of Supporting roles. Thus is touched the carriage in a central location the slot banks just not and becomes with a deflection to one of the slot bank out with his supporting role brought against this, which thereby rolls on the slot bank.

Out the possibilities for the arrangement of the support roller receptacles two are particularly preferred: The support roller receptacle can, for example, a towards the larger side surfaces open support interior for the supporting role include. The support roller can thus be arranged inside the carriage body and preferably protrudes on both sides the larger side surfaces. At a running below two-half Structure of the vehicle can be provided in each half a through hole be aligned with each other in the installation position of the two halves.

In another preferred embodiment of Trolley can support the roller bearing be integrated at least in a larger side surface, the support roller receptacle is designed as a bag that is open to the outside. in this connection the bag is preferably designed so that it is an inserted supporting role enclosing slightly more than half, with the support roller arranged with its axis of rotation parallel to the larger side surface is and the bag is correspondingly cylindrical. in this connection the bag is expediently dimensioned so that the support roller under an elastic or elastic-plastic widening of Bag, in particular the opening edges of the Bag, and / or under an elastic or elastic-plastic compression can be pressed into your pocket and in the bag captive rotatable storable.

Prefers have the roller seats perpendicular to the larger side surfaces in the carriage body introduced roller openings on. Conveniently, can the carriage body one piece connected spacer sleeves which are so aligned with the roller openings and these in their longitudinal direction prolonging are arranged, that thereby extended roller openings on both sides each end in a plane parallel to the larger side surface. Thereby can for all casters same run roller pairs are used, with a pair of barrel rollers of two rollers rotatably mounted on a roller axle consists.

In order to achieve the most compact, inexpensive and simple construction of the carriage body, the roller seats should be spaced as small as possible to each other. The minimum distance is limited by the roller diameter. As a result, in particular in the embodiment of the carriage body in which the first edge region is arranged opposite the second edge region, the inner first roller seats can be arranged close to the second coupling seat. This can limit the mobility of this coupling receptacle or a suspension bolt or the like used in this coupling receptacle by being able to abut laterally against the spacer sleeves in the case of the suspension bolt. As a remedy, it can be provided structurally that the second coupling receptacle is displaced by a required amount from the first caster receptacles, preferably toward the center of the crawler halves. Conveniently, it may be expedient additionally or additionally provided structurally that no integrally connected spacer sleeves are provided on the roller seats, which are arranged away from the first coupling seat up to a certain, maximum close distance. The spacer sleeves can then, as out below leads, if necessary, as not integrally connected to the carriage body components are attached to the carriage body. In a further advantageous development of the spacer sleeves, they can have an outer diameter, which is reduced to the free end of the spacer sleeves, preferably tapered conically.

In another constructive solution can the coupling recording in addition or even further spaced apart from the adjacent caster receptacles, preferably towards the middle of the larger side surface, be positioned and an attached Load, for example by means of a preferably on the suspension bolt circumferentially rotatable arranged load strap on the suspension bolt be hung, the tab in particular in the area of the adjacent Roller cushions are slimmed down so that when they pivot around the hanging bolt, laterally not against within a certain pivoting range the spacer sleeves can strike.

Of the Trolley body can additional multi-purpose shots exhibit. these can for example, sensor as a transmitter, transponder device for reading or reading certain data, induction or pulse generator and the like, by means of which the carriage can be controlled in and monitored. Further can These multi-purpose recordings serve as recordings for takers, for example a driver of an energy chain to the carriage body to dock. In the same way you can the multi-purpose recordings be designed as recordings for stoppers.

The Stopper can serve in installation position for limiting the travel path of the carriage body, wherein the stopper provided against, preferably positionally variable attacks e.g. in the rail can strike. The stopper receptacles should preferably point in the intended direction of travel. Furthermore, they should be in height be arranged for use coming caster recordings, so that they are in the installation position of the trolley inside the rail profile can be positioned. In a plate-like car body, the stopper shots preferably be arranged in a narrow side of the carriage body.

Generally can the multi-purpose recordings can be arranged on any side surface. In the case of its driver receiving function, a side surface is proposed which is parallel to the main attack force of a connected load, because of this larger mechanical personnel can be fed. Is appropriate Also, an arrangement on a side surface of the carriage body, the is perpendicular to the provided direction of travel, since this example Towing more problem-free through a below described Rail can be coupled through.

Especially advantageous is the carriage body from two separate vehicle halves built up. These can have one provided connecting device be connected to each other. This allows the carriage body be designed particularly lightweight, since the constructed from the car body halves Trolley body preferably shell-like, preferably with weight-reducing and Material-saving interiors and reinforcements, such as internal ribbing and the like, can be designed. Of the hälftige Construction further simplifies the construction of the movable coupling receptacle, which may have a joint body described below, the at the installation of the trolley in the intended interior inserted can be. For this purpose, the dividing plane should cut the interior appropriately so that is an insertion of the joint body possible is. Furthermore, can the Stopperaufnahmen be arranged so that they are also in the Dividing plane lie, which production engineering the shape the stopper receptacle itself and from the assembly ago the insertion provided stopper facilitates in the stopper receptacles.

Preferably, the vehicle halves should be identical. Thus, the production can be further simplified enormously, since the production on a half of the carriage 4 can restrict. Preferably, in this case the dividing plane of the carriage body should run parallel to its larger side surfaces. In addition, the carriage halves should rest in the formed as a bearing surface dividing plane. The contact surface can, in particular with an identical structure of the trolley halves, at the same time be mirror symmetry surface of the trolley body.

To the easier to assemble both halves of the car to the carriage body can the car halves Connections with mating in mating plug holes and Including plug-in pins, wherein the plug-in pins preferably project beyond the contact surface. It is obvious that the two-half body of the carriage body, preferred also the construction of identical vehicle halves, even a single coupling recording with associated Include roller mounts or more than two coupling mounts can.

For easier demolding the sidewalls of the Internal ribbing preferably perpendicular to the separation plane.

It is seen a particular advantage in that the carriage body with Help of a spraying or casting technique, in particular by means of plastic injection molding or metal diecasting and here preferably aluminum or zinc die-cast, can be produced. In this case, in particular, the two-half structure proves to be identical Carriage halves as particularly advantageous because only one injection mold is needed. Since coupling shots and rollers recordings and possibly provided screw, clip and / or connectors vertically to the larger side surfaces and thus perpendicular to the contact surface and further arranged the possibly provided Stopperaufnahmen in the division plane could be, can the carriage half with respect to the contact surface be formed completely without undercuts, creating a procedurally simple injection molding is possible. Aluminum as a material is u.a. because of its low weight suggested. Conceivable but are also arbitrary other materials. Plastic as cheaper Material is especially recommended. This can be done via the multi-component injection molding process for example higher loaded areas, such as coupling reception, caster, clips and Clipshots made of a wear-resistant plastic and / or made of a plastic of higher strength be made.

Thus, the support rollers include receptacles 37 one to the larger side surfaces 6 open support interior 41 for the support rollers 38 , The support roller mounts 37 are spaced from the first and second coupling receptacles 7 . 8th and casters 9 . 10 in the second border area 12 and overlapping in the transition 13 and thus arranged at a height in which, as in the 45 and 46 visible, the carriage 2 with a section in a guide slot 42 is arranged.

The support rollers 38 are each with a rotation axis perpendicular to a direction of travel v of the trolley 2 in the support roller seats 37 rotatably mounted. The diameter d of each in a support roller receptacle 37 arranged support roller 38 is smaller by a small amount than the width s of the guide slot 42 so that the support roll 38 only at deflection from her in 45 shown zero position laterally on an inner side of the guide slot 42 abuts and rolls on this in the direction of travel v.

The third embodiment of the vehicle halves 4 is also with an internal ribbing 43 provided in which the individual ribs 44 , each grouped together in a line, approximately parallel and in the direction of one of the two coupling shots 7 . 8th towards and thus in the direction of the approximately expected course of forces in the load case of the respective coupling receptacle 7 . 8th run, so here is a roughly diamond-shaped basic pattern of the internal ribbing 43 results.

The 33 to 39 show a fourth embodiment of the vehicle halves 4 that in the 40 to 44 to the fourth embodiment of the trolley 1 connected together. Notwithstanding the third embodiment of the vehicle halves 4 according to the 21 to 27 or the vehicle 1 according to the 28 to 32 . are the support roller seats 37 each in a larger side surface 6 integrated, with the support roller receptacles 37 as bags 45 with a part-cylindrical supporting interior 41 are formed, which is open to the outside. This includes the bag 45 the pressed-in support rollers 38 in a circumferential angle of slightly greater than 180 ° or encloses this by a little more than half. Thus, the support role 38 after being pressed in under elastic or elastic-plastic widening of the pocket 45 at their edges and / or under an elastic or elastic-plastic compression of themselves in the pocket 45 is stored captive and rotatable.

The 45 gives in a front view a carriage 2 with a carriage body 1 according to its third embodiment again, in which the support roller 38 in the through the two larger side surfaces 6 limited support interior 41 are arranged. The carriage 2 is in the first rail shown here in a cross-sectional view 39 slidably mounted and located in the already mentioned undeflected zero position in which the support roller 38 on both sides at a small distance to the insides of the guide slot 42 is arranged. Here, the carriage protrudes 2 with its movable second coupling receptacle 8th down from the first rail 39 out.

The 46 shows a side view of the in 45 shown trolley 2 with the first rail 39 and in addition to this vehicle 2 attached second rail 40 , in turn, a same carriage 2 By way of example, however, is arranged so that the carriage 2 with his first coupling shot 7 down from the second rail 40 protrudes. This illustrates once the thanks to the structure of the invention of the trolley 2 variable applications of the trolley 2 , It also becomes clear that the position of the support rollers 38 in terms of the height of the larger side surfaces 6 Here is chosen so that they are located exactly halfway up and thus no matter what orientation of the trolley 2 in the rail 39 . 40 , always at the level of the guide slot 42 are arranged.
