Integrated drive element
Proposed is an integrated drive element ( 110 ) which is particularly suitable for use in an automatic shift transmission of a motor vehicle. The integrated drive element ( 110 ) has at least one electric motor ( 112 ), with preferably precisely two electric motors ( 112 ) being provided which can be used for example for a dual-clutch transmission. Also provided is at least one electronic engine control unit ( 114 ) which is designed for controlling the functionality of the at least one electric motor ( 112 ). Said electronic engine control unit ( 114 ) in turn has a housing ( 116 ). The at least one electric motor ( 112 ) spatially directly adjoins the housing ( 116 ) and/or is at least partially integrated into the at least one housing ( 116 ).
1. An integrated drive element ( 110 ) for use in an automatic transmission, comprising:
at least one electric motor ( 112 ), and at least one electronic engine control unit ( 114 ) configured to control the functionality of the at least one electric motor ( 112 ), wherein the at least one engine control unit ( 114 ) includes a housing ( 116 ), and the at least one electric motor ( 112 ) abuts the housing ( 116 ) directly;
at least one brush carrier ( 138 ) with at least one brush ( 142 ) of the at least one electric motor ( 112 ), wherein said at least one brush carrier is integrated in the housing ( 116 ), wherein the at least one brush ( 142 ) is spring-loaded, and is pressed via at least one spring element ( 140 ) against at least one commutator ring ( 136 ) of the at least one electric motor ( 112 );
at least one sleeve ( 310 ) accommodated on at least one armature shaft ( 132 ) of the at least one electric motor ( 112 ), wherein said at least one sleeve ( 310 ) includes at least one conical guide surface ( 314 ), wherein said at least one conical guide surface ( 314 ) is configured such that when the at least one electric motor ( 112 ) is installed on the at least one housing ( 116 ), the at least one brush ( 142 ) is guided toward the at least one commutator ring ( 136 ).
2. The integrated drive element ( 110 ) as recited in claim 1 , wherein at least one sensor magnet is integrated in the at least one sleeve ( 310 ).
3. The integrated drive element ( 110 ) as recited in claim 1 , wherein the housing ( 116 ) includes at least a first fastening element ( 130 ) for attaching at least one pole pot ( 124 ) of the at least one electric motor ( 112 ).
4. The integrated drive element ( 110 ) as recited in claim 1 , wherein the housing ( 116 ) includes at least a second fastening element ( 154 ) for attaching the housing ( 116 ).
5. The integrated drive element ( 110 ) as recited in claim 1 , wherein at least one armature shaft ( 132 ) passes through the housing ( 116 ).
6. The integrated drive element ( 110 ) as recited in claim 5 , wherein at least one bearing of the at least one armature shaft is integrated in the housing ( 116 ).
7. The integrated drive element ( 110 ) as recited in claim 1 , wherein at least one plug element ( 146 ) is integrated in the housing ( 116 ).
