摘要:
The invention relates to a drive and evaluation unit for displacing an object to be displaced, particularly for raising and lowering a side window in a motor vehicle. The drive includes a commutator motor with a stator having two diametrically opposed permanent magnets. The magnets have cross-sectional shapes of a respective peripheral contour segment, having a radial inner peripheral contour segment which encompasses an armature over a respective inner peripheral angle. The armature is provided with ten grooves spaced around its periphery for holding armature windings that are configured as lap windings. The evaluation unit includes a device for determining the rotational position of the armature by evaluating the ripple count of the armature current. According to the invention, the armature windings are configured as short pitch windings, and the inner peripheral angle of the radial inner peripheral contour segment of at least one of the magnets is between 101° and 111°.

A drive unit (10) actuates drives in a motor vehicle with a first housing part (12), in particular a pole pot (12), and a second housing part (14), in particular a gear housing or electronic housing (14, 15), which can be connected with connecting elements (40), wherein the first housing part (12) features receptacles (38) for the connecting elements (40), wherein the receptacles (38) are embodied as centering holes (36) for corresponding centering pins (48), which are arranged on the second housing part (14).
摘要:
Disclosed are a method for operating a piezoelectric drive system (10) used for adjusting movable parts (12, 14), especially in a motor vehicle (13), as well as a piezoelectric drive unit (10) comprising at least one piezo motor (12) that is fitted with at least one piezo actuator (18). At least one frictional element (30) of the piezo motor (12) makes it possible to generate a relative movement in relation to a frictional surface (14) located across from the frictional element (30). The at least one piezo actuator (18) is triggered with an excitation signal (93) by means of an electronic unit (42). A response signal (130) of the drive system (10) is detected using the at least one piezo actuator (18), a change in the load of the drive system (10) being recognized as a result of a change in the response signal (130).

The invention relates to a device for adjusting a seat back (6) of a vehicle seat (4), in which a drive (9) that carries out adjusting processes is integrated. This acts on stagger gears (10, 22), with which the seat back (6) is moved within a range of inclination (13). A torsion element (24) is provided between the stagger gears (10, 22) that compensates the clearance in the stagger gears (10, 22) within a first range of adjustment (18) of the seat back (6) and functions as support for the driver motor within a further range of adjustment (19) of the seat back (6).
摘要:
An electric motor drive mechanism, in particular a window control drive mechanism for a motor vehicle, has an electric motor (10), which has a motor armature shaft (12) that is operatively connected to a gear unit (14) surrounded by a gear housing (16), and also has a motor electronics unit (18) surrounded by an electronic housing (20). The electronics housing (20) has a guide rail (22), extending radially to the motor armature shaft (12), for insertion of the electronics housing (20) via a counterpart guide (23) disposed on the gear housing (16).
