Abstract:
1. A compensation device which compensates for an angular discrepancy of a mixing drum ( 1 ) relative to a bearing bracket ( 4 ), the compensation device comprising at least a first component ( 5 ) and a second component ( 12 ) of which one of the first component ( 5 ) and the second component ( 12 ) is one of connectable and integral with the bearing bracket ( 4 ), at least one elastic element ( 11 , 15 ) is located between the first component ( 5 ) and the second component ( 12 ), a weight of the mixing drum is transmitted, via the compensation device, to the bearing bracket ( 4 ), the first component ( 5 ) has a mandrel ( 6 ) with an outer surface ( 7 ), at an end of which is attached further surfaces ( 13 ) radially extending from the outer surface ( 7 ) thus forming a cavity, and the second component ( 12 ) has a hollow body ( 8 ) with an inner surface ( 10 ) and an outer surface ( 9 ), the inner surface ( 10 ), at least partially, surrounds the mandrel ( 6 ), other surfaces ( 14 ) extend radially from the outer surface ( 9 ) and form a base, the base extends between the further surfaces ( 13 ) of the first component ( 5 ) into the cavity, the at least one elastic element ( 11 , 15 ) is located between the further surfaces ( 13 ) of the first component ( 5 ) and the other surfaces ( 14 ) of the second component ( 12 ), the further surfaces ( 13 ) of the first component ( 5 ) and the other surfaces ( 14 ) of the second component ( 12 ) are designed such that the at least one elastic element ( 11 , 15 ) is prestressed.
