Abstract: An adjustable holding device for sensors includes a main body, on and opposite of which, a bearing body supporting a sensor is adjustably held by a spherical joint. The spherical joint includes a threaded stud, fastened to the main body, that protrudes through an opening in the bearing body, and to which an opening in a body having a spherical outer surface is screwed. The outer surface is held pivotably in and co-rotatably with, about an axis coaxial with the threaded stud, complementarily spherical inner surfaces of two combined half-shells. Through rotation under external force of the combined half-shells, the body having the spherical outer surface can be screwed relative to the threaded stud by displacing the half-shells and the bearing body in the threaded stud direction.

Abstract: An adjustable holding device for sensors, including a main body, on and opposite which a bearing body supporting the at least one sensor is adjustably held by at least one spherical joint having a threaded stud fastened to the main body and protruding through a through-opening in the bearing body and to which an opening in a body having a spherical outer surface is screwed, said outer surface being held pivotably in complementarily spherical inner surfaces of two combined half-shells, and held co-rotatably together with the half-shells about an axis of rotation which is coaxial with the threaded stud and about which the half-shells are accommodated rotatably in the through-opening in the bearing body so that, by a rotation under external force of the at least rotationally coupled half-shells as to the through-opening, the body having the spherical outer surface can be screwed relative to the threaded stud by displacing the half-shells and the bearing body in the direction of the threaded stud.

Abstract: The invention relates to an electric fan, in particular, for motor vehicles, comprising an electric drive motor, a fan wheel coupled with the drive motor, and an electronic control unit for controlling the motor. In order to make the electric fan structurally more simple and more cost-effective to assemble, it is proposed that the drive motor and the control unit be arranged in a common housing, and that the housing have air vents for passage of a flow of cooling air generatable by the fan wheel, and a heat sink of the control unit be arranged at at least one air vent.

Abstract: The invention relates to an electric drive, in particular, for a fan of a motor vehicle, comprising an electric drive motor and an electronic control unit for controlling the drive motor. The drive motor comprises a commutator and associated power supply devices rubbing on the commutator, and the control unit comprises an electronic module arranged on a printed circuit board. In order to design the electric drive so that it is of simpler construction and more cost-effective to assemble, it is proposed that the drive motor and the control unit be arranged in a common housing, with the power supply devices held on the printed circuit board. The invention also relates to an electric fan with an electric drive of this kind.
