Abstract (en)
[origin: WO2010006759A1] Self-operating road pavers comprise an internal combustion engine (23) that drives a hydraulic pump for operating hydraulic motors that act as drives (24 - 28) for the chassis and other components of the self-operating street paver. At least some drives (24 - 28), in particular the transportation drive of the street paver, must also operate at the same speed under varying conditions. In order to guarantee this, in known street pavers the internal combustion engine (23) is operated at a relatively high speed. Under normal conditions, this speed is too high, so under such conditions the profitability of known street pavers suffers. The object of the invention is to operate the internal combustion engine (23) of the street paver at a variable speed that is regulated such that the drives (24, 25, 28) that require a constant speed remain substantially constant even if changing loads, and consequent changing speed of the internal combustion engine (23) occur. This allows the internal combustion engine (23) to always be operated in an optimum speed range.
