Embodiment Construction
[0031] exist figure 1 The paving machine 10 shown schematically in FIG. 2 is used to manufacture road surfaces. Any type of road surface can be involved here.
[0032] The road paver 10 is designed to be self-propelling. For this purpose it has a central drive unit 11 which is formed, for example, by an internal combustion engine with a hydraulic pump for supplying the hydraulic motor and possibly for generating energy for the electric drive and the compressor. dynamo.
[0033] The paving machine 10 has a running gear 12 which is figure 1 In the illustrated exemplary embodiment, it is configured as a wheeled chassis. The chassis 12 is driven by the drive unit 11 in such a way that the road paver 10 can be moved forward in the production direction 13 . On the front part of the road paver 10 viewed in the production direction 13 , the chassis 12 has wheels 14 which are designed as solid rubber wheels in the exemplary embodiment shown here. The rear part of the paving machi...

The invention relates to pavers (10) and to feeders, which are used to produce road surfaces. For this purpose, pavers and feeders have a wheeled chassis, in particular pneumatic tires (15). In orderto produce the road surface evenly, sufficient traction of the tires (15) is necessary. For this purpose, the tire air pressure of the tires (15) is reduced before the start of the production processand increased again for road travel. The manual adjustment of the tire air pressure to the installation conditions and / or to the operating mode of the road construction machine is time-consuming and costly. Therefore, the application creates a method for operating a self-propelled road construction machine and a road construction machine, by means of which road construction machine the traction ofthe wheeled chassis can be adjusted quickly and simply. For this purpose, according to the invention, the traction of the tires (15) is monitored and actively controlled in accordance with the operating mode of the road construction machine.
Description
technical field [0001] The invention relates to a method for operating a self-propelled road construction machine according to the preamble of claim 1 . Furthermore, the invention relates to a road construction machine, in particular a paving machine or feeder, according to the preamble of claim 11 . Background technique [0002] Paving machines and feeders are used to produce road surfaces from asphalt, but also from other road-building materials, such as concrete. The road-building material to be processed is transported from the truck to the construction site and dumped there directly into the storage container of the road-paver or feeder, which conveys the road-building material on to the road-paver. The road construction material is dumped from the truck into the storage container of the road paver or feeder during the advance of the self-propelled paving machine or feeder. Here, the paver or feeder pushes the truck forward. [0003] Pavers and feeders have carriages...
