The disclosure relates to a road finishing machine with a screed for producing a paving layer, wherein the screed includes at least one compacting unit for precompacting paving material supplied to the screed. The compacting unit includes at least one eccentric bushing mounted on an eccentric shaft supporting the same and rotatable to a desired angle of rotation to thereby continuously variably set a desired tamper stroke of a tamper bar of the compacting unit. For rotating the eccentric bushing, the compacting unit includes at least one adjusting mechanism, wherein the adjusting mechanism includes an adjusting drive mounted on the eccentric shaft and rotatable along with the eccentric shaft. The disclosure furthermore relates to a method for a continuously variable tamper stroke adjustment at a compacting unit of a road finishing machine.

Tamper stroke adjustment

The disclosure relates to a road finishing machine with a screed for producing a paving layer, wherein the screed includes at least one compacting unit for precompacting paving material supplied to the screed. The compacting unit includes at least one eccentric bushing mounted on an eccentric shaft supporting the same at a desired angle of rotation to thereby continuously variably set a desired tamper stroke of a tamper bar of the compacting unit. For rotating the eccentric bushing on the eccentric shaft, an adjusting mechanism mounted spaced apart from the eccentric shaft and at least partially rotatable along with a rotary motion of the eccentric shaft can be activated. Furthermore, the disclosure relates to a method for a continuously variable tamper stroke adjustment at a compacting unit of a road finishing machine.

A method of paving a road surface by a road paver and a compactor, comprising the following method steps: paving a road surface by means of a paving screed of the road paver, defining a target rolling field by means of an electronic data processing system, determining a relative position of the compactor in relation to the target rolling field, generating a vibration of a main driving switch of the compactor, depending on the relative position to the target rolling field.

A road paver comprises a generator, a control device and a screed, the screed comprising a basic screed and being suited to be modified, by selectively attaching or detaching broadening parts, from a first to at least a second, different screed configuration. The basic screed and the broadening parts each comprise one compacting unit and one electric heating element to be supplied with power from the generator for heating the compacting unit to prevent the laying material from adhering to the compacting unit and to finish a high-quality road pavement. The control device is configured to individually switch on or off each one of the two resistance wire windings of the heating element of the basic screed depending on the screed configuration determined by the control device to distribute electrical power generated by the generator to the individual resistance wire windings.

Method for laying down a pavement consisting of paving material with a road paver screed in which a compaction unit pre-compacts the paving material at cyclical work cycles with a selectable stroke and at a selectable frequency while the pavement is laid down at a selectable paving speed and at least the stroke is automatically adjustable in response to paving parameters.

A track-supporting roller assembly, according to the disclosure, for supporting a crawler track of a crawler chassis includes a bearing unit and a track-supporting roller rotatably coupled to the bearing unit. The track-supporting roller includes at least one supporting body made of plastic. The supporting body serves as a damper and prevents a metal-on-metal contact between track chain links of the crawler track and the track-supporting roller. The track-supporting roller assembly according to the disclosure ensures a reduced noise development in the crawler chassis. At the same time, it is possible to also reduce the wear of the track-supporting rollers to a considerable extent.

A road finishing machine with a thermographic device releasably fixed to a portion of the machine for recording a georeferenced thermographic data record of at least one region of a pavement layer. The thermographic device includes a housing in which a detection unit for detecting a thermographic data record and a further detection unit for detecting a space-related data record for the thermographic data record are disposed.

A method for laying down a pavement in which a compaction unit such as a tamper pre-compacts the paving material with a selectable stroke and at a selectable frequency while the pavement having a selectable pavement thickness is in the process of being laid down at a selectable paving speed, the stroke of the compaction unit is automatically adjustable in response to paving parameters, such as the paving speed and/or the pavement thickness, along a characteristic curve or in a characteristic map. The compaction unit includes an adjusting mechanism which is operable during the paving operation for adjusting the stroke of the compaction unit.

In a paver F comprising a combustion engine M, in particular a diesel engine, of a primary driving aggregate P, functional units having hydraulic pumpstoinclusive a travel pump aggregatewhich can be driven by the combustion engine M for supplying at least one travel drive, a generator G for supplying electric heating devices H of the paver F and/or of a paving screed B of the paver F with electric power, the generator G is driven permanently while at least one pumptoselectively can be disconnected from the combustion engine via at least one shiftable clutch K, K, K. During a heating-up phase of electric heating devices H via the permanently driven generator G at least one of the pumps is disconnected. During transport travel at least one pump of the functional units, except the permanently driven travel pump aggregateand the generator G, is disconnected. During start and, optionally, during warm-up of the combustion engine M pumps of functional units, optionally including the travel pump aggregate, are disconnected.
