<P>PROBLEM TO BE SOLVED: To provide a construction machine with a drive unit and with a cooling system that comprises a fan. <P>SOLUTION: The fan 5 is connected to the drive unit 3 by means of a controllable viscous coupling 4, whereby the viscous coupling can be adjusted in such a way that a required fan rotational speed is set on the output side. The invention furthermore describes a method for the automatic fan rotational speed regulation for a cooling system 2 in a construction machine 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
