Embodiment Construction

[0019] as from Figures 1 to 4 As can be seen in FIG. 1 , an adjusting drive comprises a housing 1 and (not shown) a cover and an output device, which is guided through the cover. The housing 1 and the cover are produced from plastic.

[0020] The housing 1 is substantially rectangular parallelepiped including a convex body 1a protruding from a bottom and having a pair of open sides disposed on the bottom. The convex body 1a is bottomed and thus part of the housing 1 and has a substantially circular cross-section on the inside. The convex body 1 a is arranged in an end region of the housing 1 with respect to the longitudinal axis L of the cuboid-shaped part and is dimensioned to accommodate a radially symmetrical electric motor 2 . The electric motor is fixed in the male body 1a and has an output shaft at its upper end protruding into the cuboid part of the housing 1 with a pinion 2a as part of a reduction gear. The upper end is formed, for example, as a motor shoulder and ...

Abstract

The present invention relates to an actuating drive which includes an electric motor (2) and a gearing arranged in a housing (1) which is open on one side and which is closed by a cover. The electric motor (2) is mounted in a recess bulge (1a) of the housing (1) which is substantially sealed off from the gearing. The configuration provides a precise positioning of the electric motor (2) relative to a first axle (3), wherein a first gear of the gearing is assigned to the same and wherein the actuating drive can be manufactured more simply and more cost-effectively than was previously possible. This is achieved in that the electric motor (2) is attached indirectly to the housing (1) by means of an accordingly shaped metal sheet (4), and is positioned in a predetermined location with no radial or axial play.

Description

technical field [0001] The invention relates to an adjusting drive comprising an electric motor and a transmission, wherein the electric motor and the transmission are arranged in a housing which is open on one side, the housing is closed by means of a cover, and wherein The electric motor is supported in a male body which forms part of the housing, largely separated from the transmission. Background technique [0002] Such adjusting drives, also called actuators, are known per se. The adjusting drive is used for adjusting the controller. Especially in vehicle construction, attention is often paid to the installation situation in this regard, in which only little installation space is available for the actuating drive and the actuating drive must therefore be designed very compactly. In this regard, the requirements for power, robustness and reliability must be met, which limits the miniaturization of the adjusting drive, ie it must have a certain minimum size for electric...
