Abstract (en)
[origin: US2015043971A1] A self-propelled construction machine for working roadways or surfaces includes a machine frame supported by ground engaging units, and a milling drum which can rotate about an axis of rotation extending transverse to the advance direction of the construction machine. The construction machine includes a cooling device for spraying the milling tools of the milling drum with a coolant from a coolant reservoir. The cooling device is designed such that at least one coolant jet extending parallel to the axis of rotation of the milling drum is produced. A single coolant jet which extends transverse to the working direction of the milling drum is sufficient for cooling the milling tools. When the milling drum is rotating, the milling tools of the milling drum pass through the coolant jet successively. Owing to the relatively close arrangement of the milling tools in the circumferential direction of the milling drum, the time intervals in which a milling tool is not passing through a coolant jet are relatively short, and as a result the coolant consumption can be reduced.
