The invention relates to a construction machine, in particular a road milling machine, recycler or stabiliser, comprising a machine frame (4) that is carried by a chassis (2), a working roller (6) and a drive train (8), which comprises at least the following elements: a drive motor (10); a tractive element gear (12) for the mechanical drive of the working roller (6), comprising a drive element, adriven element and a tractive element (30); a unit (14) for switching the torque between the drive motor (10) and the working roller (6); and a unit (16) for driving at least one hydraulic pump. According to the invention, the elements of the drive train (8) are divided into at least two groups, the first group (3) containing at least the drive motor (10) and the second group (5) containing at least the drive element (11) of the tractive element gear. The first and second groups (3, 5) are interconnected by means of an articulated coupling unit (20).
