Description

Die Erfindung betrifft einen Straßenfertiger der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to a paver which Preamble of claim 1 specified type.

Bei einem aus EP-A-0 489 969 bekannten elektrischen Straßenfertiger sind das Primärantriebsaggregat bei seit Jahrzehnten für Straßenfertiger konventioneller Bauweise vor dem Führerstand in das Chassis eingegliedert und der Führerstand so hoch gesetzt, daß der Fahrzeugführer nach vorne über das Primärantriebsaggregat hinwegblickt. Ein elektrischer Straßenfertiger ist ein Straßenfertiger, in dem zumindest wesentliche Funktionskomponenten, wie Fahrantrieb, Fördererantrieb, Querverteilerantrieb und dgl. elektrisch betreibbar sind. Der Verbrennungsmotor des Primärantriebsaggregates dient hauptsächlich oder ausschließlich als Antrieb des Drehstromgenerators, der den Strom für die elektrischen Antriebe erzeugt. Der Verbrennungsmotor kann den Drehstromgenerator direkt oder über ein Zwischengetriebe antreiben. Der Vorteil des sauberen und umweltfreundlichen elektrischen Straßenfertigers wird unter bestimmten Einsatzbedingungen durch den Nachteil des für die Umwelt bzw. Umgebung schädlichen oder störenden Verbrennungsmotor geschmälert, der auch den hinter ihm stehenden Fahrzeugführer mit Lärm, Vibrationen und Abgasen belästigt. Beispielsweise in einem Tunnel oder auf einer überbauten oder abgedeckten Baustelle können Motorenlärm und Abgase unerwünscht sein. Ferner erfordern Reparaturen und Wartungsarbeiten am Primärantriebsaggregat im Straßenfertiger lange und kostenintensive Stillstandszeiten.Diese Arbeiten sind aufgrund oft beschränkten Zugangs mühsam. Bei modernen Straßenfertigertypen mit Kabine muß diese aufwendig demontierbar oder klappbar sein, andernfalls sind u.a. aufgrund der Bauhöhe beim Transportieren Sondertransporte oder Umwege nötig.In an electrical known from EP-A-0 489 969 Asphalt pavers are the primary drive unit at Decades for conventional pavers integrated into the chassis in front of the driver's cab and the The driver's cab is set so high that the driver can move looks over the front of the primary drive unit. An electric paver is a Paver in which at least essential Functional components such as travel drive, conveyor drive, Cross distributor drive and the like. Electrically operable are. The internal combustion engine of the primary drive unit serves mainly or exclusively as a drive of the three-phase generator that provides the electricity for the electric drives generated. The internal combustion engine can the three-phase generator directly or via an intermediate gear drive. The advantage of the clean and environmentally friendly electric paver under certain operating conditions due to the disadvantage that is harmful or disruptive to the environment Internal combustion engine diminished, which also the rear driver standing by him with noise, vibrations and exhaust fumes. For example in a tunnel or on a built-up or covered construction site engine noise and exhaust gases may be undesirable. Further require repairs and maintenance work on the primary drive unit long and cost-intensive in the paver Downtime.This work is due to frequent restricted access tedious. With modern road paver types with cabin this must be disassembled or be foldable, otherwise due to the Height when transporting special transports or detours necessary.

Um kostspielige Stillstandszeiten eines wartungs- oder reparaturbedürftigen Straßenfertigers zu vermeiden, läßt sich im Austausch eine gleichartige Baueinheit auf das Chassis setzen, mit der der Straßenfertiger sofort weiterarbeiten kann. Die hinter dem Führerstand auf dem Chassis angeordnete Baueinheit führt ferner zu dem Vorteil einer besseren Sicht auf den Vorderteil und Gutbehälter des Straßenfertigers vom Führerstand aus, und zu einer verringerten Lärm- und Abgasbelastung des Fahrzeugführers. Dazu kommt, daß der Führerstand wesentlich tieferliegt als bisher, was Transportprobleme wegen der Bauhöhe beseitigt. Die abgenommene Baueinheit kann ferner als Stromversorgungsaggregat an der Baustelle oder an jedem beliebigen Ort benutzt werden. Für schwerwiegende Reparaturarbeiten, die an der Baustelle nicht ausführbar sind, läßt sich die Baueinheit abtransportieren, während der Straßenfertiger an Ort und Stelle verbleibt oder mit einer Austausch-Baueinheit weiter betrieben wird. Bei Einbauarbeiten in einem Tunnel oder auf einer überdachten Baustelle oder auf einer Baustelle innerhalb eines Gebäudes läßt sich die abgenommene Baueinheit an einer weniger störenden Stelle des Tunnels oder außerhalb des Tunnels bzw. außerhalb des Gebäudes aufstellen und mit dem Straßenfertiger durch Kabel verbinden, der dann mit erheblich reduzierter Geräuschentwicklung und ohne Abgase fernversorgt arbeitet.The independent can be used for maintenance or repair work Remove the assembly from the chassis. The work on the primary drive unit can then be conveniently carry out. In addition, there is largely unhindered Access to the functional components and other parts in the Chassis. To costly downtimes road paver in need of maintenance or repair can be avoided, a similar unit can be exchanged put on the chassis that the paver uses can continue working immediately. The one behind the cab assembly arranged on the chassis also leads for the benefit of a better view of the front part and the paver's material container from the driver's cab off, and to reduced noise and exhaust pollution the driver. Add to that the cab lies much deeper than before, which causes transportation problems eliminated because of the height. The removed one The unit can also be used as a power supply unit be used on the construction site or at any location. For serious repair work on the Construction site can not be carried out, the unit can transport away while the paver is on Remains in place or with an exchange unit continues to operate. For installation work in one Tunnel or on a roofed construction site or on a construction site within a building removed assembly in a less disturbing place of the tunnel or outside of the tunnel or outside of the building and with the paver connect by cable, which is then significantly reduced Noise generation and powered remotely without exhaust fumes is working.
