A drive system for a mixer barrel for absorbing weight of the mixer barrel (). The drive system communicates with a base () via a weight supporting element which supports the mixer barrel () and enables relative movement therebetween. The weight supporting element comprises at least one distortable elastic element () enabling the movement between the drive system and the base (). The at least one elastic element () supports the weight of the mixer barrel () above the at least one elastic element (). The drive system () has at least one component () which limits movement of the drive system () and increases a distance between the drive system () and the base () such that a torque strain on the drive system () is braced by the base ().

Drive for mixing drum with elastic element arranged between bearing incorporating drive system and base

A drive for a mixing drum has a compensating device () for the purpose of compensating the motions between a drum () and a bearing bracket (), which consists of a first component (), an elastic element (), and a second component ().

Gearbox for concrete mixer

Axially and radially-loadable bearing which damps in an axial direction for elastic mounting of machines, machine parts, and/or vehicle parts. This bearing has an outer part and two elastomeric or rubber springs located between an inner, often rotating, part and an outer part, which form a cavity area which is preferably filled with damping fluid and in which there is a partition separating the cavity into two chambers. The partition comprises a rigid sliding part guided on the inner part and a rigid fastening part connected in a fixed manner to the outer part. The two rigid parts are connected to one another by means of an elastomeric or rubber thrust washer. Preferably, there is a throttle in at least one of the rigid parts. As a result of the arrangement of a rubber thrust washer between the sliding part and the fastening part, the bearing can absorb radial and Cardan motions at the same time as it absorbs axial loads without jamming, and without the occurrence of a appreciable change of the throttle opening cross-sectional area.
