CONSTRUCTION MACHINE AND MILLING ROLLER

摘要

The invention relates to a construction machine comprising a machine chassis frame (2) in which a milling roller (18) is mounted such that it can rotate. Said milling roller (18) comprises a roller base body (19) which is driven b y a milling roller drive device (11 to 15) via a transmission unit (32) and comprises a milling tube (25) that can be coaxially slid onto the roller bas e body (19) and can be fastened to the same in an exchangeable manner. The out er surface (46) of the milling tube is equipped with cutting tools. According t o the invention, the milling tube (25) comprises fastening elements (28) which radially project from the inner surface (44) and with which the milling tube (25) can be fastened in a rotationally fixed manner to the roller base body (19) or to a part that is connected to the roller base body (19).
