Description

.Modular construction of your Hmonian, especially bus.

The present invention relates to a modular road utility vehicle, in particular: a bus, the car body of which is arranged in any number and order perpendicular to the longitudinal axis of the commercial vehicle, n. it has windows and door modules. Depending on the number and arrangement of these, a complete commercial vehicle family can be formed with a high degree of manufacturing and quality assurance, significant cost reduction in operating costs. a stiff, possibly multi-layered, ethoswoven web is embedded.

A particularly new and significant feature of our solution is that each module is a self-supporting load unit whose chain forms a self-supporting koeshest, eliminating the need for a conventional chassis or any other load-bearing element system.

The present invention ensures that each module becomes an independent load-bearing unit by providing a "ring-like" closed outer and inner corpus callosum with a closed spacing to increase the cross section of the outer casing. some modules are molded from their material to the entire body of the car body: longitudinal axis perpendicular to their components! JuLzarn cup couplings are mounted on the mandrel, assembled and bonded to each other.

Through the use of a feedstock tube design, the present invention provides a total rolling stock of commercial vehicles of the same category, thus reducing power consumption, thus providing an ideal solution for hybrid vehicles. At the same time, due to the ring-closed modules and other, if appropriate, known constructional solutions, their strength properties and load bearing capacity are at odds with the prior art.

It is known that the significant increase in fuel prices and the emphasis on environmental protection have increased the market demand for low-cost road utility vehicles with minimal emissions. Fossil fuel requirements can be significantly reduced Hybrid / powered vehicles However, this solution has not been widely adopted due to the fact that manufacturers are converting their traditional vehicles into hybrid vehicles - thus requiring very high net weights to use increased power. Virtually only prototype hybrid vehicle solutions, there are some aato hood manufacturers with a greater number of burns in the US area of belief. state test project.

Neoplan (Neoman) GmbH, for example, casts a steel body with a synthetic resin, but this does not result in significant weight loss, it is important in corrosion protection, which increases the service life of the new vehicle and khles it.

The \ AB1 f, \ ord Amcrfean Bús hvl ístoes, while maintaining the traditional jUrtnu-fclepitcc, made the upper part of the body of the body using composite materials according to the horizontal division; using experience gained in shipbuilding, using reinforcements. The disadvantage of this solution is that they require a significant amount of steel reinforcement to be applied to provide sufficient strength; at the same time, the conventional assembly follows all hehekem where balsa is subject to machining (eg, drilling), due to its absorbency, it is dispersed in a short time. Due to the horizontal division, this solution involves the construction of different molds for each type of vehicle (category), which represents a very significant cost increase compared to conventional manufacturing technology - thus producing only one category. The vehicle is not self-supporting.

Significant reductions in manufacturing costs result from known solutions that re-use commercial vehicle bodywork by reusing standard building blocks, optionally modules.

As the hell of a muscle solution, the sexy patent specification 931 5,6Sktromszamn, in which buses strike a steel trolley of trolley buses, namely a front and a rear module, and the window and door window modules they provide. Bz. Depending on the number of the latter, each yard family can be formed with a significant cost. The description does not cover. for each module, at the same time details the design and positioning of the chassis and the wheels on the semi-hinges and their accessories for each type presented.

Modular body structure is known. US 4.254.9S? See also U.S. Patent No. 5,600,198. in which each unit (module), with the exception of the module including the wheel troughs, has a frame structure consisting of several slabs of the same construction and located along the edges of each module (cell) in the shape of a quasihasah. After each module has been secured to one another, load-bearing members, namely, IF iron beams and a floor resting on them, are fastened to the bottom of the formed body of the bodywork, along its entire length. The bodywork gets its final appearance after exterior and interior flailing. The novelty of the solution lies in the load-bearing eco-trailer, while the developed commercial vehicle has a jet lag.

Modular construction applications can also be found in other areas of the vehicle industry. US Pat. No. 6,227,125 describes a modular construction of the bodywork of a railway vehicle and is considered to be an extension of DE-B-1,158,541, provided that the solution is perpendicular to the longitudinal axis of the bodywork. These semi-modules (C-shape) of various configurations, consisting of horizontal and vertical halves, are interconnected along their horizontal walls. The solution of US Patent No. 6,227,125, using relatively short fol modules, provides easier and more economical production, while providing great variability. The applicants will szendvies ^ / Erke / dispenser, middle layer positioned between the inner and outer fiber-reinforced plastic layers of thermal and acoustic insulation to ensure a smaller dead load provides the conventional solutions used herein are described be considered as the solution to the essential feature of "force-transferring ^five modalities detail with which each top module, and longitudinal sections formed by two half-modules are connected to each other .The load bearing capacity is particularly significant in the lower horizontal walls "recesses ¹ ', running along the entire length of the assembly fartőgerendák placed.

The aim of the present invention was to create a state-of-the-art, thus environmentally friendly, low-maintenance and long-life road commercial vehicle, which, thanks to its structure, can be optimally adapted to urban and suburban public transport and at the same time our goal is nunel lower self-weight bi / tosUaso \ oh „md> az. reduce operating costs and use modern (hybrid) drives.

In view of the state of the art, the modular system was chosen for the design of the commercial vehicle, following the approach that a commercial commercial vehicle is sequentially functional. can be considered as a chain of discrete units (modules). In this way, the correct response acids of each functional unit can be constructed, depending on their order and number, into a commercial vehicle of the appropriate category.

In order to minimize wet weight, we have selected & composites from the materials available in the state of the art. It has been discovered that if we remove a suitably molded composite material with a ring-sealed double chafe structure, a year to fill the closed space with a lightweight material to increase the cross-section, and this self-contained sandwich structure forms the the strength characteristics of the units created will, by themselves, be life-sustaining with respect to any application to the vehicle, including load-bearing capacity. Based on our discovery, model experiments have been conducted which have largely proved the correctness of our assumption; the needle parameters were also better than previously known solutions. The advantageous effect, i.e. that each module is a self-supporting load unit, is associated with the use of a "ring-like" composite shell with an intact surface, which necessarily involves the use of a known low-weight sandwich structure.

This double enclosed shell structure remains intact during manufacture and during subsequent construction of the complete bodywork, with individual modules designed individually as load-bearing units, with their own material perpendicular to the longitudinal axis of the commercial vehicle. , with fasteners and then glued together. (It should be noted here that the term "ring-like" in our title does not refer to the shape, but to the infinite, closed-loop training.)

In accordance with the foregoing discovery, the present invention relates to a modular road utility vehicle which, when mounted, is known for its energy sources, front and rear gears, and its drive train, all necessary steering elements on its front wall, communications and information technology, , regulating, running, ventilating and air-conditioning ícnds / veins rcnde'ke / .k es coexistent is composed of core material filling the space of the outer intestine of the komoo / h material and located along its longitudinal axis perpendicular to its longitudinal axis joined together and fixed with adhesive. Particularly new features of our solution are that the individual modules - namely the front wheel arch and front wheel arch module, the rear wheel arch and the casing of any window / door assembly in any order and number are "ring-closed" , forming an intact surface, so that each module is a self-supporting load unit, which, when glued together, forms a self-supporting body.

For the purpose of the present invention, each module has a hollow encircling groove formed from its own material perpendicular to the longitudinal axis of the vehicle. a matching socket prototype is provided.

In our solution, the composite of the outer and inner sheaths of the inner and outer shell of each "ring-like" closed module is made of high-strength, endless fibers, e.g. carbon fiber, glass fiber - composed of, if necessary, multi-layered webs, are reinforced with their primed closed spaces as quasielastic, homogenized core material by PCR. Foam or epoxy foam.

The road utility vehicle of the present invention can be implemented in a variety of lanes depending on the number and order of the modules for windows and doors. The following embodiments are particularly preferred;

Thus, the road utility vehicles of the present invention are assembled from modules designed as self-supporting load units into self-supporting body bodies, the preferred embodiments of which are

1-4. 6A and 6A show a further embodiment.

In Figure 1, a preferred embodiment of an I pattern modem I is shown in a loving condition. The right and left side walls 9a and the front wall 5, which are connected to the floor 7a with a front wheel arch 7, have a curved roof 3a on both sides, in which, in our exemplary embodiment, longitudinal section installation channels will be described later.

These clusters, which are functionally separated, form an "annular" closed unit, known per se in the form of a sandwich structure; eg> the inner and outer composite shell of the composite shell is filled with the quasle-lastic core of the closed shell, (Refer to Figure 5 for its design.)

It is well appreciated in Fig. 1 that each of the fccopical portions in different planes is always curved, without undercut, in a continuous manner in their material, both along the outer and inner shells (shells).

A.l. feontniodui has an internal ktabknasa with a traditional vehicle cross, but with new features. Since the solution in our embodiment does not use a side door, there is no "bottleneck" for passenger flow and a free space 2 is provided between the front wheel arches 7 to accommodate the wheelchair of a handicapped passenger (This is illustrated in FIG. 10). visible.)

In addition to the ergonomic aspects, the design of the shape 1 is essentially determined by the strength of the coolant segments. THE? in particular, there are, for example, metal inserts (implanted brackets) on the forehead 5, particularly in the interlocking double-head structure, all of which. they improve the strength characteristics and are designed to accept the complete instrumentation of the vehicle.

Λ-eyed I Ifooímodul muga'uu tongue is an elementary end product for incorporating gum snlunktunt blackberry. The bee on the 5 front walls ages to adjust the adjustable safety, balanced steering column for all the years of steering, including the front axle and the element system required to install it, complete with the instrumentation, communications and information system. as well as the elements of heating, ventilation, air-weaving. All these are not shown in the figure, but their design is well known,

Figure 2a shows a perspective view of a window module. In the practice of the present invention, the length of each module, including the window module II, was chosen in accordance with twice the seating distances used in conventional buses (approximately 1.5 to 1.7 inches); this is also advantageous in terms of strength, but they are also sheared by the vehicle lacquers, which are also different due to their design. and allows for multiple seating arrangements.

As shown in Figure 2, this window module 11 integrates the window poles 4b and the roof 3b with mounting ducts 8b and its floor, which are connected to the sides 9b, into a single closed unit. The load bearing capacity of the .11 window module and the stiffness of the heel significantly increase at the junction of the side walls 9b and the floor bb, which are smoothly aligned with their planes, which form a seat. The support seats 10 have the same basic materials and designs as the individual modules (double composite shell sandwich structure, filled with plastic) and are manufactured with tools recessed into the floor 6b. In this way, if an 11-window module is omitted on one or both sides of the seat support (seat benches), the flatness of the floor 6b can be ensured by a flat insert.

The roof 3b also has an emergency exit opening 11,

Figure 2, b shows a rear view of the window module il The figure illustrates well the roof 3b curved at its two edges, which provides an adequate amount of corner stiffening. The installation channels 8 in roof 3b assemble the complete vehicle channels throughout the assembly of each module. form. If necessary, reinforcing tubes (rods) of similar thermal expansion, similar to those of the module material, are inserted into these channels, other than under normal load.

Optionally, using a suitable insert, the window module 11 is also provided with two passageways. This shape of heat can go separately, not shown - it is used on articulated vehicles as the last unit (module) of the front car body (see Figure 111).

Fig. 3 is a perspective view of a door module 111, Bz in all enclosure dimensions, with a window module ii, so that they can be derived from one another by producing the same tool using different inserts, utilizing the capabilities of complex tools. The right side wall 9b has a vertical glide line. exchanger. the bi-back seat bench in / erts / ers / amanak kh can be used to produce a mely door module that has a door opening 25a bounded by 1.2 door posts. In the embodiment shown in Fig. 3, a ramp 16 is formed in place of the support seat 19 using a suitable wood insert. As shown in the figure, the Ili door module integrated a complete flat floor 6b with the auxiliary columns 12 carrying the curved side wall 9c and the elements for mounting the door actuator and the roof 3b resting on these only 4b windows / eru into a closed unit,

Figure 4a is a perspective view of an IR rear module, while Figure 4b shows the same module in side view and Figure 4c shows

The rear module IV is a floor panel 6c with a rear wheel arch 13 and a side wall 9c with a window window, an I? rear .wall and. integrates the roof c based on these into a single closed unit, The roof 3c of the IV rear module is reinforced because when fitted it carries the evaporator unit of the vehicle's air conditioning unit and, if transformed into a trolley with a utility,

The rear wall 17 - a -ke is shown as being divided into a rear wall 26 and a window opening 18.

Sits on the 17 back plates. on the floor 6c, a rear row of seats 15 formed as a podium is provided, which, similarly to a plurality of reclining benches, provides sufficient angular rigidity of the module. The rear seat row 15 has the same material and structure as the modules (see Fig. 4, a).

When mounted, the l'V rear module is the most complex unit. Carries the affected chassis with the complete drive chain and its service units, as well as the complete power supply of the vehicle. All of these units are located in the space below the podium-shaped rear seat row 15 or in connection with the rear wheel arches 13, fixed with inserts placed in the double-shell sandwich structure,

The side opening shown in Figure 4b shows a mounting opening 14 as well as a rear opening 26 shown in the back view 4e for good mounting and servicing.

Figures 5, a and 5b illustrate the construction of a known sandwich structure for each module and their assembly into a jam body in Figs. Figures A to B are shown in detail in side view and in section.

The inner shell 19 and outer shell 20 of Figures 5, a and 5, b are known in the art to form a closed sandwich structure filled with core material 21 The material of the inner and outer shells 19 is a composite (thermosetting matrix) of high strength infinite natural or synthetic reinforced with a web of fibers (preferably carbon fiber or glass fiber). The closed space between the two inner shells 19 and the outer shells 20 is filled by a non-contacting core material, preferably PUR or epoxy foam kL. some: open at the ends of the modules - ·· in a plane perpendicular to the longitudinal axis of the vehicle, with a smoothing groove 22 on one side and a ··· 23 capillary profile on the other end ···

The assembly of the modules in the vehicle is known in the art of positioning fitting and profits; u <, blindly, th, i, o V \ U, R, se, /, e, with ongldeoen u 22 grooves, ilL 23 coupling profiles along. It can be clearly seen that the groove 22 and the groove 22 respectively. Capesotoprofile 23: is made of a double composite shell sandwich construction material, so that the space between the inner and outer outer shells 19 is completely closed. The developed, zippered solution significantly increases the size of the surfaces to be glued, while being more resistant to the complex stresses during use. The adhesive, in addition to the materials used, is also significantly influenced by the mgus / tas height and. choosing the correct ratio of distance between two elements; the optimal value of which was determined by model experiments.

Here we refer to Figures 2-4. 8a also illustrates the role of the mounting channels 8. In cases other than normal load (operating) conditions, a safe solution is provided by inserting a mereum tube (rod) into the mounting ducts 8. Preferably, the material is also composite or has a material close to the hougulasr coefficient.

The embodiments of the elements shown in Figures 2-4 demonstrate that the design of each module has always been a basic consideration for the accessibility of the passenger compartments, the flat floor. At the same time, we also need to adapt to user needs, so Figure 6 shows one. A .1 'feontmodule is provided which has a door aperture 25.

In the embodiment of Figure 6, the driver's lap is a, a. 7 front passageways, found · trained on a 27-step podium forming an associated shell structure that widens from the 25 door openings. The figure also shows the configuration of the dashboard 24. (Otherwise, it has the fenkelonab parts described in Figure 2 which form a continuous closed unit.)

In the following, by way of example, preferred embodiments of commercial vehicles constructed as modules of the "load-bearing" segment of the "ring-bus" described in Figures 2-4, which are various categories of city buses, are shown.

The figure also shows the openings for the lance plate on the roof portions 3b. This approximately 5m long vehicle can accommodate 155 passengers v driver + wheelchair.

As can be seen in the figure, in addition to the row seats, individual shoulder pads 9 corresponding to the soft seat order are used, and the shoulder pads 9 are preferably placed on individual brackets through which heated air can be circulated.

Of course, the foregoing embodiments are merely examples of a preferred embodiment of the present invention; our need for protection is not limited to these, and in addition to the city buses shown, trolleybuses and road vehicles can be designed to meet the demands of the circumstances, according to the circumstances.

While discussing the present invention, we did not mention the vehicle in the photographic system, but as mentioned in the introduction, our primary aim was to create a hybrid-powered vehicle, which can be achieved economically with significant weight reduction. (Of course, other known drive tools can also be used, such as in the case of trolleybuses / 1 \ - Zero Fnussion Vernele)
