Description

TECHNICAL AREA

The present description relates to a paver of the type described in claim 1. It further relates to a feeder.

TECHNOLOGICAL BACKGROUND

In construction machines, and in particular self-propelled construction machines, a large number of machine components and assemblies must be arranged in a limited space. These build sometimes very large. In addition to a primary power generation unit, typically a diesel engine, for example, a hydraulic pump and resource tanks must be arranged. Thus, a fuel tank must be arranged, which should naturally be dimensioned as large as possible in order to avoid frequent tank breaks and related work interruptions. In addition, there are tanks for the hydraulic fluid, and due to today's regulatory requirements regarding the Pollutant emissions typically also required for aids to pollutant reduction in the exhaust. Here, for example, a tank for urea should be mentioned. Due to the desired capacity of these tanks they build very voluminous. Due to the use of construction machinery at low speeds and in the state, at the same time high power requirements, it is necessary to arrange large-sized radiator with powerful fans. At the same time, it is necessary to arrange exhaust aftertreatment and purification systems that are able to effectively after-treat the entire exhaust gas mass flow to meet the emission standards. In addition, a plurality of fluid-carrying lines must be arranged.

Asphalt pavers or pavers for pavers often use high-performance generators with a capacity of up to 60 kW and even more. installed. These serve to operate an electric screed heating and / or to heat conveyors for the property to prevent setting of bituminous material in the conveyors. At the same time built-in bins must be placed in road pavers and feeders, which should also have the largest possible capacity. Thus, especially in road pavers and feeders, the length of an aggregate space in which said machine components are to be arranged, severely limited because the total allowable length of the machine is also generally limited. Furthermore, on the chassis of road pavers and feeders to arrange a conveyor for the built-in, which further also the possible height of the unit space is limited.

In summary, therefore, especially in road pavers and feeders, a large number of sometimes large and bulky machine components and units must be arranged with a small footprint. This results in a necessary very compact arrangement of the machine components in the aggregate space, especially road pavers and feeders. This runs the demand for good accessibility of the machine components for maintenance and Repairs work against. In general, many machine components must be disassembled to gain access to other machine components.

PRESENTATION OF THE SUBJECT OF THE PRESENT DESCRIPTION

A road paver or a feeder should be specified. In accordance with a more specific aspect of the present description, a pavement paver or feeder is provided which allows easier access to the machine components in the aggregate space. In particular, the paver or feeder to be specified so that an unobstructed access to maintenance-intensive machine components is possible, the disassembly of as few other components is required, or even completely unnecessary. In particular, a disability-free access to a primary power generating unit of the machine should be possible. The power generation unit is in exemplary embodiments a diesel engine, which is further arranged in particular with its crankshaft in the direction of travel of the machine. In certain embodiments, the power-generating unit is arranged at least substantially centrally and / or slightly off-center on the chassis of the paver or the feeder.

Furthermore, according to further aspects of the subject matter described herein, the resource tanks should also be accessible as unhindered as possible.

Facilitating access to the components in this way reduces the susceptibility to maintenance and repair errors, and significantly reduces the required downtime. This also results in improved efficiency.

Other effects and advantages of the objects described herein, whether explicitly stated or not, will become apparent in light of the present description.

This is achieved by means of the object specified in claim 1.

The presently described arrangement of machine components in a work space solves tasks that occur in asphalt pavers and feeders to the same extent, and, as stated in the introduction, in a particularly accentuated manner. Both can also be summarized below as "machine" or "construction machine" reference. If, in the context of the present description, reference is made below to a machine or a construction machine, this is to be understood as meaning a road paver and / or a feeder.

Thus, there is described one of the paver or feeder comprising machine components disposed within an aggregate space, the aggregate space having at least one aggregate space access opening, and at least one first machine component pivotally mounted about a pivot axis to a chassis of the construction machine. The at least one first machine component is arranged in the area of the unit space access opening. In particular, the at least one first machine component obstructs and / or obstructs the aggregate space access opening and thus the access to machine components arranged behind it in the pivoted-in state in the unit compartment. The at least one first machine component is pivotable out of the aggregate space about the pivot axis through the aggregate space access opening. Analogous to a book cover can thus be "exfoliated" by swiveling the at least one first machine component of the aggregate space. This is a disability-free access to an inside, that is, the side facing away from the access opening side, which allows at least a first machine component. Likewise, a disability - free access to one of the Aggregate space access opening ago seen behind the at least one first machine component lying further machine component allows.

It will be readily apparent to those skilled in the art, in light of the present disclosure and understanding of technical terminology, that machine components within the meaning of the present specification are components that are operatively coupled or connected to at least one other machine component located within the aggregate space, and thus components , in particular functional components, represent a machine arranged in the unit room or a machine block consisting of different machine components. That is, a machine component within the meaning of the present description contributes to the function of a machine block or is even required for proper function. According to another view, a machine component contributes to the function of at least one other machine component or is required for its function. According to another view, a machine component for your function relies on or is supported by another machine component.

In other words, a machine component is characterized in that it is or is in operative connection with at least one further machine component, and in particular stands or is arranged with at least one further machine component in a functional operative connection.

In a more specific view, a machine component is connected by means for power, fluid and / or signal transmission to at least one other machine component. In particular, the abovementioned agents produce the abovementioned functional coupling. The means mentioned are in particular means which establish a physical connection. The means may be, for example, rigid or flexible shafts, or conduits, in particular connecting conduits, in particular electrical connecting conduits, pneumatic and / or hydraulic conduits pneumatic and / or hydraulic power and / or signal transmission, conduits for the guidance of fluids, in particular liquids and gases and the like, these lists are not to be understood as limiting or concluding.

In particular, the at least one first machine component is functionally and / or coupled by means of the type mentioned with at least one further machine component, or is in operative connection therewith, wherein the at least one first machine component and the at least one further machine component by the pivotability are movable relative to each other. More specifically, it can be provided that the at least one further machine component is arranged stationarily to a chassis of the paver or the feeder. The at least one other engine component may include a power plant, such as a diesel engine.

Engine components within the meaning of the present specification accordingly include, but are not limited to, a tank, a radiator such as a charge air cooler, a water radiator or oil cooler, hydraulic control blocks, manifolds, oil filters, and the like. An oil cooler may be, for example, a hydraulic oil cooler or a lubricating oil cooler. For example, a tank may be a tank for fuel, lubricant, hydraulic fluid, urea for exhaust treatment, or cooling water. All these components have in common that, in the sense of the understanding of a person skilled in a machine component, they are functionally and / or physically coupled or connected to at least one further machine component or are in operative connection.
In certain embodiments, all of the first machine components are pivotable about a common pivot axis. In particular, all first machine components are arranged in a component block. By this is meant that all first machine components are arranged stationary relative to each other. For example, as discussed below, all of the first machine components may be attached to a pivotable unit room door or be arranged a frame of the unit room door. It is not necessary that the first machine components are attached to each other; but they still form a component block with the door or frame of the door. This means that all the first machine components can be swung out of the unit compartment by a single swivel actuator.

It should be noted in this context that in relation to a paver or a feeder and thus to the unit room "up" and "down" clearly defined terms. The machine itself defines a direction of travel and in particular a forward direction of travel, such that " in direction of travel at the front "and" in the direction of travel at the back "are also clear and clearly defined terms, as well as" in the direction of travel to the side "," in the direction of travel left "and" in the direction of travel to the right ". By contrast, "lateral" or "sidewall" with respect to the unit space distinguishes this orientation only from the top and bottom of the unit space. Therefore, "lateral" or "sidewall" relative to the engine compartment space can mean both lateral and front or rear with respect to the direction of travel.

In a further embodiment of the subject matter described herein, a second unit room access opening is disposed. At least one second machine component is pivotally mounted about a second pivot axis to the chassis of the machine such that the at least one second machine component is pivotable out of the unit space through the second unit room access opening. The statements made above with regard to the at least one first machine component can likewise be applied to the at least one second machine component mentioned here.

In certain embodiments, all second machine components are pivotable about a common pivot axis. In particular, all second machine components are arranged in a component block. This is understood to mean that all second machine components are arranged stationary relative to one another. As explained below, for example, all second Machine components may be arranged on a pivotable unit room door or on a frame of the unit room door. It is not necessary that the second machine components are attached to each other; but they still form a component block with the door or frame of the door. This allows all second machine components are swung out of the unit room by a single pivoting operation.

The said aggregate space access openings may be arranged on opposite side walls of the unit space. This allows a two-sided access, in particular to a lying between said first and second machine components area of the unit space or there arranged machine components. In particular, it allows free access to the entire unit space.

An aggregate space access opening may extend at least substantially over an entire sidewall of the aggregate space, and more specifically, both aggregate space access openings may extend across an entire sidewall of the agglomerate space, respectively. This also allows for the best possible access to the entire engine room because dead angles and undercuts within the engine room are avoided or at least minimized.

In certain embodiments, an engine room access opening is located on a left or right side of the engine room in the direction of travel. Furthermore, a first unit room access opening in the direction of travel can be arranged on the right and another unit room access opening in the direction of travel on the left. The lateral arrangement in the direction of travel of the at least one engine compartment access opening provides for best possible access to the engine compartment from one side to which there are generally no other components of the machine which could obstruct access to the engine room access opening. An access from the front and / or back, based on the direction of travel, is at a Road paver or a feeder not unhindered possible. There, for example, a built-in bunker or a screed are arranged.

According to a further aspect of the presently described subject matter, at least one further machine component is arranged behind at least one pivotably arranged machine component when viewed from an engine room access opening. That is, at least a first or at least a second swing-out machine component is disposed between the at least one further machine component and an engine room access opening. By pivoting the pivotally mounted machine component, access to the further machine component through said aggregate space access opening is provided through the corresponding unit space access opening. In exemplary embodiments, the at least one further machine component is disposed between the at least one first machine component and the at least one second machine component, such that by swiveling at least one of the first and second machine components through one of the unit room access openings, access to the at least one other Machine component through the respective unit space access opening is made possible.

In certain embodiments of the described subject matter, the at least one further machine component is arranged stationary relative to the chassis. In this case, the at least one further machine component can be connected to the chassis via vibration dampers, such as rubber mountings.

Furthermore, the at least one further machine component may comprise or be a power generation unit. More specifically, the power plant may be an engine, particularly a diesel engine. In certain embodiments of the subject matter described herein, the engine is arranged with its crankshaft along or parallel to the direction of travel of the paver or the feeder. Due to the arrangement of the Motors with longitudinally arranged crankshaft and the resulting arrangement of the engine with a longitudinal extent parallel to the working and / or direction of travel, this type can be carried out particularly suitably in the manner described herein. It may ancillaries, such as a hydraulic pump or a generator, be coupled to the power generation unit and in particular be provided for driving by the power generation unit. These ancillaries can be arranged stationary to the power generation unit and can be arranged in particular stationary to the chassis.

In this respect, a road paver or a feeder is disclosed, which includes a longitudinally installed motor as a primary power generating unit. By this is meant that the engine is arranged with its crankshaft parallel to the working and / or driving direction of the paver or the feeder. The engine is for example a diesel engine. The road paver or feeder can also be designed according to the embodiments described here. Due to the arrangement of the engine with longitudinally arranged crankshaft and the resulting arrangement of the engine with a longitudinal extent parallel to the working and / or direction of travel, such a paver or feeder may be particularly expedient according to the present disclosure. On the one hand, the arrangement of an engine oriented parallel to the direction of travel crankshaft favors an arrangement of the machine components in the aggregate space according to the present description, in particular with arranged laterally on the machine unit space access openings. This is due to the fact that the motor in the arrangement described has a greater longitudinal than transverse extent, which is why in this arrangement, the machine components in the transverse direction of the machine can be arranged side by side. On the other hand, a particularly good access to a longitudinally installed engine can be ensured by the described arrangement of the machine components in the unit room.

In further embodiments, an aggregate space door is arranged on an aggregate space access opening, and in particular on each aggregate space access opening, which is pivotable about a pivot axis to the chassis of the paver or the feeder. By means of the unit room door, the unit room access opening can be closed. At least one of the first and / or second pivotally mounted machine components may be connected to an equipment room door, such that when the equipment room door is opened, the associated machine component or machine components associated with it swing out or swing out. It is understood that the machine components connected to the unit door are arranged, in particular, on an inner side of the door which points into the unit space. When the unit door is opened, the associated machine components thus also pivot out. Thus, at the same time as opening the unit door, the above-described free access to the unit space, or to further machine components arranged in the unit room and / or to the rear side of the components connected to the door, is made possible. Under the back of these machine components is to be understood as the side of the machine components, which, with the door closed, are arranged to the interior of the unit space hinweisend. By connecting the machine components to a door or a frame of the door, the machine components arranged thereon form a component block of machine components arranged stationary relative to one another. The machine components may be attached to the door. The pivot axes of the door and the associated machine components are in particular parallel to each other. When the machine components in question are attached to the door, the pivot axis of the door also simultaneously forms the pivot axis of the machine components.

It can be provided that a service flap is arranged in at least one pivotable unit room door, which in particular allows access to a machine component connected to the unit room door. It may in particular be possible through For example, the service door can gain access to, for example, a tank or tank neck of that tank connected to the engine room door without having to open the engine room door.

It may be provided that a pivot axis or the pivot axes of the machine components and / or the doors upright, that is, in particular, in particular, upright and further in particular perpendicular, are arranged. It follows that the doors and / or the pivotally mounted machine components are swung out in a horizontal plane. This significantly simplifies handling since the doors and / or components do not need to be lifted when swinging.

It can nevertheless be provided that auxiliary devices for pivoting the pivotally mounted machine components and / or the doors are arranged. Likewise, auxiliary devices may be provided, which make it possible to keep the doors and / or machine components in a specific swung-out position. These may be, for example, hydraulic and / or electric servo drive devices or gas pressure dampers. This facilitates the handling of the swing-out components, especially if it can not be guaranteed that the machine is on a horizontal and level surface.

As already indicated, in certain embodiments of the article described herein, an aggregate space access opening extends at least substantially over an entire sidewall of the aggregate space. The at least one pivotably arranged machine component can fill at least substantially the entire unit space access opening. The largest possible aggregate room access opening facilitates access to the unit room. If as large as possible and / or many machine components are swung out of the unit room, this also increases the accessibility to the unit room.

The above hinged unit room door is in certain Embodiments a unit room side door, which is arranged in the direction of travel of the side of the unit space and laterally limits the unit space in the direction of travel. In particular, can be arranged in the direction of travel right and left a hinged side door. The advantages of the side access in the direction of travel and in particular the two-sided access are described above.

In particular, at least one machine component is connected to each pivotable unit door, such that it swings out with the unit door. Thus, when opening each unit room side door machine components are swung out, with the above-mentioned beneficial effects.

The at least one swing-out machine component may comprise a tank. It may further comprise at least one cooler. Optionally, the at least one swing-out machine component may also include a radiator fan. This list gives examples and is not exhaustive. In general terms, as machine components which can be swiveled out, in particular machine components are suitable which on the one hand are as bulky as possible in order to swing out the largest possible volume of components out of the unit space and thus allow best possible access to the machine components remaining in the unit space when the machine components are swiveled out. On the other hand, it may prove to be advantageous if the swing-out machine components require as few and flexibly to be executed connecting lines, in particular fluid connection lines, which impede the swing-out and pivoting movement as little as possible. This condition is met for example by a tank and / or a cooler.

In other aspects, the at least one swing-out machine component may include hydraulic control blocks or valve blocks. Likewise, the at least one swing-out machine component a Include oil filter.

The aggregate space can be arranged below a driver's cab. This takes into account in a special way the space in a road paver or feeder, in which at a front in the direction of travel side as large as possible Einugugutbunker is arranged.

Furthermore, at least one hydraulic control device, which belongs to the components remaining in the assembly space and in particular can continue to be arranged stationarily relative to the chassis, can be arranged in the unit space. In this case, the at least one hydraulic control device can be arranged on a floor and / or on a front and / or rear wall of the unit space. When these devices are correspondingly flat, they do not hinder access to further components remaining in the assembly space, in particular in the case of said arrangement. Another advantage may be seen in the fact that the numerous connection lines of the one or more hydraulic control devices need not be moved, which favors a clear installation.

Furthermore, at least one cooler may be provided on an upper boundary wall of the unit space and in particular above the at least one machine component remaining in the unit space.

• wenigstens eine Maschinenkomponente ist in dem Aggregateraum angeordnet und vorgesehen, in dem Aggregateraum zu verbleiben,
• wenigstens eine erste ausschwenkbare Maschinenkomponente ist benachbart zu der im Aggregateraum verbleibenden Maschinenkomponente angeordnet, und ist zwischen der im Aggregateraum verbleibenden Maschinenkomponente und einer Aggregateraum-Zugangsöffnung angeordnet, wobei die ausschwenkbare Maschinenkomponente um eine Schwenkachse zu dem Chassis verschwenkbar ist und durch Verschwenken um die Schwenkachse aus dem Aggregateraum herausgeschwenkt werden kann. Die im Aggregateraum verbleibende Maschinenkomponente ist insbesondere ortsfest zu einem Chassis des Strassenfertigers oder Beschickers angeordnet. Die im Aggregateraum verbleibende Maschinenkomponente umfasst insbesondere ein Leistungserzeugungsaggregat. Derart liegt bei einem Ausschwenken der wenigstens einen schwenkbaren Maschinenkomponente eine Seite der im Aggregateraum verbleibenden Maschinenkomponente frei, und es ist ein Zugang zu der besagten im Aggregateraum verbleibenden Maschinenkomponente ermöglicht. Insbesondere liegt durch Ausschwenken der wenigstens einen ersten schwenkbaren Maschinenkomponente ein Leistungserzeugungsaggregat mit gegebenenfalls daran angeordneten Nebenaggregaten an einer ersten Seite des Leistungserzeugungsaggregats frei und es ist ein Zugang zu dem Leistungserzeugungsaggregat ermöglicht.

According to a further aspect of the present description, a road paver or a feeder is described in which machine components are arranged in an assembly space as follows:

• at least one machine component is disposed in the aggregate space and arranged to remain in the aggregate space,
• at least a first swing-out machine component is disposed adjacent to the machine component remaining in the aggregate space, and is disposed between the machine component remaining in the aggregate space and an aggregate-space access opening, wherein the swing-out machine component is pivotable about a pivot axis to the chassis is and can be swung out by pivoting about the pivot axis of the unit room. The machine component remaining in the unit space is in particular arranged stationarily to a chassis of the paver or feeder. In particular, the machine component remaining in the unit room comprises a power generation unit. In such a manner, upon swinging out of the at least one pivotable machine component, one side of the machine component remaining in the assembly space is exposed, and access to the said machine component remaining in the unit space is made possible. In particular, by swiveling the at least one first pivotable machine component, a power generation unit with any ancillary equipment disposed thereon is exposed on a first side of the power generation unit and access to the power generation unit is enabled.

In an exemplary embodiment, at least one second pivotable machine component is disposed on a second side of said machine component remaining in the aggregate space adjacent to the machine component remaining in the aggregate space and is pivotable about a pivot axis out of the unit space. In such a way, upon swinging out of the at least one second pivotable machine component, a second side of the machine component remaining in the assembly space is exposed and access to the said machine component remaining in the unit space is made possible. In particular, by swiveling the at least one second pivotable machine component, a power generating unit with any ancillary equipment disposed thereon is exposed on a second side of the power generator and access to the power generator is made possible.

It goes without saying that the described subject matter also according to this view in accordance with the features described above and can be developed further described specific embodiments.

In a further aspect, the subject matter of the present description is characterized in that the arrangement of the machine components within the unit space is divided into at least two and in particular three juxtaposed component groups. In particular, the machine components are divided within the unit space in parallel to the direction of travel of the machine and across the direction of travel of the machine juxtaposed component groups. The components of the outer component groups or an outer component group are pivotably arranged such that the components of the pivotally arranged component group or the pivotally arranged component groups can be pivoted out of the unit space. It is thus possible to expand the component groups analogous to the arrangement of the leaves in a book or, so to speak, "open". Thus, the lying in the pivoted state between the component groups sides of the component groups or the components arranged there are freely accessible.

Furthermore, an aggregate room door for a paver or a feeder of the aforementioned type is disclosed wherein at least one machine component is connected to the unit room door. The said machine component may in particular comprise at least one tank. The aggregate space door is particularly provided to be pivotally mounted to a chassis of the paver or the feeder. In particular, the unit room door may comprise a frame. On the frame, the machine components connected to the door can be arranged and in particular fastened. Furthermore, a cover element can be provided on one side of the frame, which is provided for an arrangement on the outside of the unit space.

The above-described embodiments of the described objects can of course be combined with each other. Further, not specific disclosed embodiments and modifications of the teaching of this document will be readily apparent to those skilled in the art.

EMBODIMENTS

In FIG. 1 a road paver 1 is shown as an example of a self-propelled road construction machine of the type described here. The asphalt paver comprises a tractor 10 and a screed 20. The screed is coupled by means of pulling arms 21 on the tractor, and is towed during operation of the paver by the tractor in the direction indicated by the arrow at 2 working direction. The tractor includes a chassis 11. In the direction of travel or direction forward a bunker 12 is arranged for built-in. Furthermore, the paver comprises a non-illustrated, but known per se, conveying device for paving material, which is transported from the built-in bin bunker 12 to a rear end of the chassis of the tractor, and there deposited in front of the plank 20 and a not shown, but the Professional also common, transverse distributor is distributed transversely to the direction in front of the screed. Furthermore, a driver's cab 13 and an aggregate compartment 14 are arranged. The engine compartment is located below the driver's cab and behind the built-in bin. Within the aggregate space, various machine components are arranged, such as a power generation unit, a hydraulic pump, hydraulic control units, and tanks for various operating fluids. The power generation unit may in particular be a diesel engine. An exhaust 15 for the exhaust gases of the power generation unit is led out of the unit room and opens, for example, above the cab. To allow access to the unit room, for example, to perform maintenance and / or repair work, an aggregate space access opening is provided, which is closed by an aggregate room door 16. The unit-space access opening is laterally arranged, with respect to the working or driving direction 2, in such a way that lateral access to the unit space is made possible. As shown in the illustration, the unit room access opening extends at least substantially over the entire side wall of the unit space 14. The unit room door 16 is, for example by means of hinges, pivotally mounted about a pivot axis 17 relative to the chassis. To continue to gain access to, for example, a filler neck without opening the entire engine compartment door a service door 18 is integrated in the unit room door 16. At an upper side of the unit space and above the machine components arranged therein, coolers 19 are arranged. These may include air coolers or water coolers, and serve, for example, for cooling the power generation unit, the hydraulic fluid and / or charge air and the like.

In the FIG. 2 is a highly schematic view of the tractor 10 of the paver from the FIG. 1 along in the FIG. 1 drawn line AA shown. In the aggregate space 14, a component group 31 is arranged stationary to the chassis. The component group 31 includes a power generation aggregate. The power-generating unit may be fixedly connected to the chassis by means of rubber buffers or other suitable elastic elements adapted to decouple the chassis from vibrations of the power-generating unit. For example, the power-generating unit is a diesel engine, which is arranged with its crankshaft parallel to the working direction 2. In addition, the stationary component group may comprise, for example, ancillary components of the power generation unit, for example a hydraulic pump and / or a generator and / or an exhaust aftertreatment and / or exhaust gas purification device. Said component group 31 is provided to remain in the unit room. Furthermore, other machine components, such as hydraulic switching blocks, may be fixedly connected to the chassis. These are in the highly schematized view of FIG. 2 not shown. In the working direction laterally of the stationary component group pivotable machine components 32, 33 and 34 are arranged. These may include tanks for pavers of the paver. Operating materials may be, for example, fuel, hydraulic fluid, or urea, which serves to reduce pollutants in the exhaust gas of the power generator. Furthermore, the pivotally mounted engine components may be or include radiators or hydraulic switching units or valve blocks. The pivotable arranged in the direction of work 2 left of the stationary machine components Machine components 32 and 33 are disposed on and connected to an equipment room door 161. In this respect, the components 32 and 33 are arranged stationary relative to each other and constitute a component block. The unit door 161 is arranged about a pivot axis 171 rotatable to the chassis of the paver and connected to a side wall of the unit space. Due to the rotatable mounting of the unit door 161, the latter can be swung out laterally along with the machine components 32 and 33 arranged thereon along a direction indicated by 173 in order to open them. In an analogous manner, on the right side of the tractor or on the right of the component group 31 remaining in the assembly unit, machine components 34 are arranged on a unit room door 162 and connected thereto. The aggregate space door 162 is rotatably connected about a pivot axis 172 with the structure of the asphalt paver. The aggregate room door 162 can thereby be dispensed along with the door-mounted machine components 34 for opening along a direction indicated by 174. For example, the service door 18 located on the door 161 provides access to the machine component 33 without having to open the entire unit room door 161. This can prove to be expedient, in particular, if, for example, the machine component 33 is a tank, in particular a fuel tank, which requires comparatively frequent access. In this case, the filler neck can be arranged such that it is accessible through a covered by the service flap 18 service opening.

FIG. 3 shows the machine shown schematically from the FIG. 2 with the unit room doors 161 and 162 open. When the unit room doors are opened, the machine components 32, 33 and 34 attached thereto are swung out of the unit room 14 through the unit room access opening. Characterized in that the laterally arranged machine components 32, 33 and 34 are pivoted out of the unit space, a free lateral access to the machine components 31 remaining in the unit room is made possible. The accessibility is automatically established when a Aggregate room side door is opened. It may prove advantageous if machine components are arranged on and connected to the pivotable unit room doors, which on the one hand are voluminous and, on the other hand, require the smallest possible number of connecting lines, which can additionally be made flexible. The maximum possible opening angle of the doors or swivel angle of the components may well be more than 90 °, for example up to 180 °. By swiveling voluminous machine components, when swinging out, a maximum of space is created in the unit room and the best possible access to the machine components remaining in the unit room. Due to the fact that machine components are selected for the swing-out arrangement, which require the smallest possible number and flexibly to be executed connection lines, the swiveling out of the unit room doors is hindered as little as possible. In certain embodiments, the component group 31 remaining in the aggregate space substantially comprises only the power generation aggregate, and aggregates disposed thereon and / or driven by it, such as a generator or a hydraulic pump. Furthermore, other machine components that are as compact and flat as possible, such as hydraulic switching units and / or valve blocks and / or coolers on the ground, on a front and / or rear boundary wall, and / or on an upper boundary wall of the unit space 14 may be arranged. In this way, said components do not interfere with lateral access to the component group 31 through the aggregate space access openings. Thus, by opening the unit room doors, for example, disability-free access to the power generation unit can be made possible.

In another aspect, in this embodiment, the machine components are arranged in the aggregate space in three component blocks or "layers" arranged next to one another. In this case, two component blocks are pivotally mounted and are moved out of the unit space when opening the unit room doors, such that only still a middle, stationary component block remains in the aggregate space. In this way, each component block is easily accessible with open unit room doors. In the manner of book pages, the machine components or component groups are arranged in layers. By "flipping" a machine component, access is provided to the machine components located inside of the unit room access openings or doors.

Although the subject matter of the present description has been explained with reference to selected exemplary embodiments, these are not intended to limit the claimed invention. The claims include embodiments that are not explicitly illustrated, and embodiments that depart from the examples shown are nevertheless covered by the claims.
