Milling unit and earth working machine
The invention relates to a milling unit (28) for an earth working machine (10), encompassing a milling drum (32) and a milling drum housing (30) supporting the milling drum (32) rotatably around a milling drum axis (R); the milling drum housing (30) surrounding the milling drum (32) on several sides; the milling unit (28) comprising a closed operating-medium circuit (44a, 52, 54, 56, 58) that encompasses an operating-medium pump (54) that is embodied to drive the operating medium to circulate in the operating-medium circuit (44a, 52, 54, 56, 58); the operating-medium circuit (44a, 52, 54, 56,58) encompassing a heat exchanger (52); the heat exchanger (52) being arranged on the milling drum housing (30). Provision is made that the heat exchanger (52) is embodied for flow impingement by a cooling gas separate from the operating medium; and that a cooling fan (60), which is embodied to drive the cooling gas for flow impingement onto the heat exchanger (52), is arranged on the milling drumhousing (30).
本发明涉及用于地面加工机(10)的铣削设备(28)，铣削设备包括铣削辊轮(32)和使得铣削辊轮可围绕铣削辊轮轴线(R)转动地受到支承的铣削辊轮箱(30)，铣削辊轮箱(30)从多个侧面包围铣削辊轮(32)，铣削设备(28)具有闭合的运行介质回路(44a、52、54、56、58)，运行介质回路包括运行介质泵(54)，运行介质泵构造成，驱动运行介质以在运行介质回路(44a、52、54、56、58)中循环，运行介质回路(44a、52、54、56、58)包括换热器(52)，换热器布置在铣削辊轮箱上。根据本发明规定，换热器构造成用于与运行介质分开的冷却气体流动并且在铣削辊轮箱(30)上布置散热器风扇(60)，散热器风扇构造成，驱动冷却气体流向散热器(52)。
