Automotive machine for producing carriageways

A soil stabilizer apparatus, comprising:

• a chassis having a direction of travel from a rearward end toward a forward end;
• a forward running gear supporting the forward end of the chassis;
• a rear running gear supporting the rearward end of the chassis, at least one of the running gears being driven so that the apparatus is self-propelled;
• first and second pivot arms having upper ends pivotally connected to first and second sides, respectively, of the chassis and defining a pivotal axis transverse to the direction of travel;
• a working drum located between the front running gear and the rear running gear and mounted on the first and second pivot arms, the working drum including a drum axis extending transversely to the direction of travel;
• a combustion engine arranged between the pivot arms and behind the forward running gear and in front of the rear running gear, the engine having an output axis co-axial with the pivotal axis so that the pivot arms and the working drum pivot about the output axis;
• and
• a power transmission device received by the first pivot arm to transfer drive power from the engine to the working drum, the power transmission device including a belt drive including a first pulley driven by the engine, a second pulley for driving the drum, a drive belt connecting the first and second pulleys, and a tension pulley deflecting and tensioning the drive belt, the belt drive pivoting with the working drum and the pivot arms about the pivotal axis.
