Starter unit

摘要

The invention relates to a starter unit (1), comprising the following: an input (E) which may be coupled to a drive input; an output (A) which may be coupled to a drive output; a starter element (1) in the form of a hydrodynamic coupling comprising a pump wheel (4) and a turbine wheel (5) which together form a toroidal working chamber (6) and a pump wheel shell (10) which is coupled to the pump wheel (4) in a rotationally fixed manner; and a converter lockup clutch (7) comprising at least two clutch disks which may be brought into frictional functional engagement with each other, directly or indirectly, by means of further transmission means-a first clutch disk (8) and a second clutch disk (9). The first clutch disk (8) is rotationally fixed to the pump wheel shell (10) and the second clutch disk (9) is rotationally fixed to the turbine wheel (5). Means (11) for producing a contact force for producing the frictional connection between the first clutch disk (8) and the second clutch disk (9) are also provided.
