A method for producing a control device for mechanically controlling a component. The control device may have a device housing including a motor accommodating space in which an electric motor is arranged. The electric motor may include a motor housing having a stator and a rotor, the rotor including a rotor shaft. The method may include selecting an electric motor from a plurality of electric motors each suitable for a specified application. Each of the plurality of electric motors may have a different respective axial motor length and may have a same respective motor cross section. Further, the method may include adapting the motor accommodating space to the respective axial motor length of the selected electric motor.

Control device and corresponding production method

An electric control device for actuating an actuator may include an electric motor including a rotor for driving the actuator and a substantially cylindrical stator housing having an axial lower side and a circumferential shell. The axial lower side may merge into the circumferential shell via a circumferential edge. The control device may also include an equipment housing including a substantially cylindrical motor mounting which at an axial end is sealed by a mounting bottom and in which the electric motor is arranged with the axial lower side facing the mounting bottom. On the axial lower side, a central, axially projecting motor end portion may be disposed. In the motor mounting between the circumferential shell of the stator housing and the equipment housing, an annular space may be defined. The annular space may be at least partly filled with an adhesive which attaches the stator housing to the equipment housing.

Control device with an electric motor fixed in a motor mounting

A controlling device may include an actuator for mechanically actuating a component. The actuator may be driven by an electric motor. The controlling device provides a return spring. In the case of a failure of the electric motor, the return spring brings about a shifting of the actuator into a starting position. The return spring may be mounted in the controlling device so that it prestresses the actuator into the starting position with a predetermined minimum restoring force.

Controlling device for the mechanical actuating of a component

A control device may include an electric motor having a stator and a rotor with a driveshaft, an output shaft, a transmission having a worm drive with a worm and a worm wheel, and a drive axis of the drive shaft extending inclined to an output axis of the output shaft. The worm may be arranged non-rotatably and may mesh with the worm wheel, which may be rotatably arranged on the output shaft and non-rotatably connected to a first gear wheel, which may be rotatably arranged on the output shaft and may mesh with a second gear wheel, which may be rotatable about an intermediate axis extending parallel to the output axis and may be non-rotatably connected to a third gear wheel, which may be rotatable about the intermediate axis and may mesh with a fourth gear wheel, which may be non-rotatably arranged on the output shaft.

Control device and associated production method

An actuating device for mechanically actuating a component may include a housing having first and second housing parts lying against one another in a separation plane and fastened to one another, and an electric motor arranged in the first housing part and having an input shaft. The device may also include an output shaft rotatably mounted at least on the second housing part and penetrating a wall thereof, the output shaft one of (i) being connected externally on the second housing part with an actuating element for mechanical coupling with the component which is to be actuated, or (ii) forming an actuating element for mechanical coupling with the component which is to be actuated. The device may further include a gear connecting the input shaft with the output shaft, and having an output gearwheel rotatably connected with the output shaft. The second housing part, in relation to an axis of rotation running perpendicularly to the separation plane, may be able to be fastened to the first housing part in at least two different rotation positions. The output shaft may be arranged eccentrically to the axis of rotation on the second housing part. At least one of the first and second housing parts may have at least one bearing point for rotary bearing at least one additional gearwheel. In a first rotation position between the housing parts, the gear without the additional gearwheel may connect the input shaft with the output shaft with a first transmission ratio. In a second rotation position different from the first rotation position, between the housing parts, the gear with the additional gearwheel may connect the input and output shafts with a second transmission ratio different from the first transmission ratio.

Actuating device

A positioning device for mechanically actuating a component may include a housing with first and second housing parts welded to one another via an axial welded connection. The first and second housing parts may have integrally formed first and second bearing points, respectively, of a bearing within the housing. The positioning device may also include a gearing fixed in the housing, the gearing having an output shaft penetrating the second housing part and being drive-connectable with the component outside the housing, and an output wheel non-rotationally fixed on the output shaft and rotatably mounted in the bearing. The positioning device may further include a rotary position detector with a permanent magnet and a Hall sensor, the permanent magnet being arranged on a gear wheel of the output shaft or on the output shaft at an end face of the output shaft, and the Hall sensor being arranged on the first housing part. End faces of the first and second bearing points may interact axially with first and second bearing surfaces, respectively, of the output wheel located opposite each other. The bearing may have a predetermined axial play defined by a difference between an outer axial distance between the first and second bearing points and an inner axial distance between the first and second bearing surfaces.

Positioning device and a method for producing the positioning device

An adjusting device for mechanically actuating a component may include a housing, which may include a first housing part and a second housing part that abut on one another along a dividing plane. The device may also include an electric motor for rotationally driving an actuator arranged on the second housing part and configured to couple to a component. The first housing part and the second housing part may be fastenable to one another via a plurality of first fastening elements disposed on the first housing part and a plurality of second fastening elements provided complementary thereto and disposed on the second housing part. The plurality of first fastening elements and the plurality of second fastening elements may be arranged evenly distributed in the circumferential direction such that the first housing part and the second housing part are fastenable in a plurality of different rotational positions.

Exhaust gas turbocharger comprising adjusting device

A valve train may include a camshaft having first and second slide guides, first and second cams mounted axially adjacent in torque-proof manners on the camshaft, and a cam follower adjustable between a first position, in which the cam follower is drivingly connected with the first cam, and a second position, in which the cam follower is drivingly connected with the second cam. The valve train may also include an adjustment arrangement having adjustable mechanical first and second engagement elements for axially adjusting the cam follower between first and second positions. Each engagement element may be adjustable between basic positions, in which no contact exists with a respective one of the slide guides, and switching positions, in which the respective engagement element cooperates with the slide guide. Each engagement element may have a spring that prestresses it into the switching position. The valve train may further include an arresting device and an actuator for each engagement element, wherein the arresting device, when in a locked position, holds the associated engagement element in the basic position, and the actuator releases the arresting device.
