Abstract: A torsional vibration damper for a drive train includes an axis of rotation, a multi-flange damper for damping torsional vibrations, a torque limiter unit for limiting a maximum transmissible torque, an outer hub connecting the multi-flange damper to the torque limiter unit for torque transmission, and an inner hub for connection to a transmission input shaft. The multi-flange damper has a plurality of flanges. The torque limiter unit is arranged radially inside the multi-flange damper and includes an inner plate and an outer plate. The outer hub is arranged radially between the multi-flange damper and the torque limiter unit and the inner hub is arranged radially inside the torque limiter unit. The outer hub includes an external toothing engaged with each of the plurality of flanges and an internal toothing engaged with the outer plate.

Abstract: The invention relates to clutch disc comprising a torsional vibration damper which has an inlet part and an outlet part and a spring device operatively arranged in the peripheral direction between the input part and the output part, wherein the spring device is formed from the first and second spring elements connected behind one another and separated by an intermediate flange, and a centrifugal pendulum which has a pendulum mass carrier arranged about an axis of rotation of the clutch disc and pendulum masses accommodated on same on pendulum paths for oscillation and arranged in a distributed manner over the periphery. In order to improve the insulation effect of the torsional vibration damper and the centrifugal pendulum and/or better adjust same to the required application, the pendulum mass carrier is coupled for conjoint rotation with the intermediate flange and centrally accommodated on the output part.

Abstract: A surface cleaning machine is provided, including a chassis, at least one sweeping roller which is held on the chassis via a swing arm device, an adjusting device for adjusting a position of the at least one sweeping roller relative to a floor/ground, a sensor device which determines one or more quantities characterizing the relative position of the at least one sweeping roller to the floor/ground, and a control device which controls the relative position of the at least one sweeping roller to the floor/ground, wherein the adjusting device acts on the swing arm device, wherein a position of the at least one sweeping roller relative to the floor/ground is adjusted via a pivotal position of or at the swing arm device, and wherein the sensor device is associated with the swing arm device and detects floor/ground contact of the at least one sweeping roller via the swing arm device.

Abstract: A sweeping vehicle is provided including a disc brush and a holding device for the disc brush, the holding device having a holding part and a holding arm pivotably connected to the holding part, the holding device held on the vehicle by the holding part, and the disc brush held on the holding arm. The vehicle includes an adjusting device having an adjustment member of variable length engaging the holding arm, the holding arm being pivotable relative to the holding part upon change in length of the adjustment member. The holding device includes a brush carrier pivotably mounted on the holding arm and a coupling device coupling the brush carrier to the adjusting device, the brush carrier being pivotable relative to the holding arm upon change in length of the adjustment member for pivoting the disc brush about a pivot axis aligned at a slant to the axis of rotation.

Abstract: An exchangeable sweeping brush device for a carrier vehicle is provided. The device has at least one sweeping brush which is rotationally drivable about an almost vertically oriented axis of rotation of the brush and is held on a supporting frame, the supporting frame being detachably connectable to a supporting fork of the carrier vehicle, which is pivotable about a first horizontal pivot axis oriented transversely to the longitudinal axis of the vehicle. The supporting frame comprises a first supporting assembly on which the at least one sweeping brush is rotatably mounted, and a second supporting assembly which is detachably connectable to the supporting fork, the first supporting assembly being connected to the second supporting assembly for pivotal movement about a second horizontal pivot axis and being detachably connectable to the carrier vehicle by at least one tension member. A sweeper having such a sweeping brush device is also proposed.

Abstract: The invention relates to an automotive sweeper with wheels for traveling along a ground surface and with at least one sweeping brush rotatingly drivable for sweeping the ground surface and with a dirt container adapted to be acted upon with a vacuum by a suction unit via a suction conduit and connected to a suction port via an intake line for the purpose of receiving sweepings. In order to develop the sweeper further in such a manner that it achieves an improved cleaning result with as little use of energy as possible it is suggested in accordance with the invention that the suction conduit be integrated into the dirt container at least in sections, wherein the outlet of the intake line opening into the dirt container is arranged next to at least one inlet area of the suction conduit.
