  • Patent number: 11447918
    Abstract: A milling unit for an earth working machine including a milling drum and a milling drum housing; the milling unit comprising a closed operating-medium circuit that includes an operating-medium pump that is embodied to drive the operating medium to circulate in the operating-medium circuit; the operating-medium circuit including a heat exchanger through which operating medium flows during circulating flow of the operating medium; the heat exchanger being arranged on the milling drum housing. Provision is made that the heat exchanger is configured for flow impingement by a cooling gas separate from the operating medium; and that a cooling fan, which is embodied to drive the cooling gas for flow impingement onto the heat exchanger, is arranged on the milling drum housing.

  • Patent number: 11274401
    Abstract: An earth working machine (10), in particular a road milling machine, a stabilizer, or the like, having a milling drum (30) that is mounted rotatably on a machine frame (11) and is populated or populatable on its outer circumference with working tools (31); the working tools (31) to come into contact, during working operation, with the ground that is to be worked to remove it; a drive unit (20) drives the milling drum (30) by means of a drive motor (21); an input drive shaft (33) couplable to the drive motor (21) is attached to the milling drum (30); and a ballast element, constituting a kinetic mass (57), increases the kinetic energy of the milling drum (30). The kinetic mass (57) is couplable to or decouplable from the rotatable milling drum (30), or a rotational member indirectly or directly coupled to the milling drum (30), via a shiftable coupling (55).

  • Patent number: 10774482
    Abstract: The invention relates to a working device for a ground-processing device having a milling drum with a milling drum tube on whose surface working tools are mounted in a projecting manner and are intended to come into contact with the material to be milled during the milling process, wherein the working device has a powertrain for driving the milling drum. In order to improve the running smoothness of a ground-processing machine, provision is made according to the invention for at least one load weight to be arranged, preferably interchangeably, on the powertrain and/or on the milling drum to increase the kinetic energy.

  • Patent number: 10024005
    Abstract: In a self-propelled road milling machine for working road surfaces, comprising a machine frame, comprising a milling drum mounted to rotate and extending in axial direction transverse to the direction of travel, and a milling drum housing enclosing the milling drum, where the milling drum comprises multiple tools circumferentially preferably arranged in the shape of a helix, where the tools, except for the axial peripheral area, feature a specified mutual line spacing, it is provided for the following features to be achieved: an oscillation drive exercises an oscillation stroke on the axis of the milling drum moving to and fro in axial direction relative to the machine frame, where the rotating movement of the tools is superimposable with an axial movement parallel to the axis of the milling drum, the stroke of which is adjustable to the line spacing between two axially neighboring tools.
