Abstract: A control device includes a first circuit carrier with electrical components that are electrically conductively connected to one another and a second circuit carrier with electrical components that are electrically conductively connected to one another. The first circuit carrier and the second circuit carrier are electrically conductively connected to one another. The second circuit carrier is fixedly connected in thermally conductive fashion to a fluid-tight thermally conductive carrier element. The second circuit carrier and the carrier element are arranged in a cutout of the first circuit carrier. The carrier element has better thermal conductivity than the first circuit carrier and can be thermally conductively connected to a heat sink. The carrier element is integrated in fluid-tight fashion in an internal region of the first circuit carrier.

Abstract: Blocking apparatus, as well as a gearbox drive unit containing such a blocking apparatus, as well as a method for production of a gearbox drive unit such as this for blocking any rotary movement of a shaft (14) with respect to a housing (16) of a gearbox drive unit (10), having a first blocking element (32) and having a second blocking element (34) which can be moved axially with respect to the first blocking element (32) by means of an electromagnet (44) and at least one return element (42), in order to produce a connection between the first blocking element (32) and the second blocking element (34) such that they cannot rotate with respect to one another, with the electromagnet (44) having an inner pole (47) which is surrounded by an electrical coil (45), and with the inner pole (47) having an axial projection (51) which engages in a corresponding opening (64) in the second blocking element (34), for axial guidance and centering.
