Abstract:
The invention relates to a window-lift drive for motor vehicles, comprising a cable drum (3) mounted in a rotational manner inside a housing, where said cable drum is encircled by a cable connected to the window pane. A crank bolt (1) mounted rotatably in a wall of the housing is connected with and drives the cable drum (3). The housing also contains a braking device, comprising a bell-shaped brake cap (6) and a brake spring (7) positioned inside the bell-shaped brake cap (6). A coupling element, in particular a fork (12) or similar part, can be rotated by the crank bolt (1) and is positioned at a radial distance in relation to said crank bolt (1). A prestressed elastic element (11) is placed between the crank bolt (1) and the coupling element.
Abstract:
The output shaft (3) of the gear should be mounted alone in a pot-shaped gear housing (1) which can be sealed with a gear housing lid (2); to this end, a first bearing is provided between one shaft end and a bearing pot (1.11) on the pot floor (1.1) of the gear housing and a second bearing is provided between a bearing neck (2.1) of the gear housing lid (2) and a shaft collar (4.1) of a concentric driver disc (4) driven by a gearwheel (6), this shaft collar being injection-moulded around the other shaft end and extending outwards through a central opening of the gear housing lid with a gear output member.
Abstract:
The invention relates to a device for supporting the self-locking function of an adjusting motor (1). Said device is linked with a drive-side rotor shaft (5) that interacts on the output side with an output shaft (8) of a transmission, and the motor housing (2) of the adjusting motor (1) is linked with the transmission housing (20) of the transmission. Followers (12) are articulated to the rotor shaft (5) of the adjusting motor (1), said followers establishing and releasing the self-locking connection (21) with the transmission housing (20).
Abstract:
An electro-mechanical actuator (1) including a plurality of motors (2, 3) for driving an output shaft (10). The actuator may be incorporated into a window lift mechanism (30), such as a mechanism including a dual rack and pinion assembly (1314). According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e.g. clutches. A clutch according to one embodiment includes locking pawls (1616, 1618) that resist back-drive. In another embodiment, locking cams (2108) rotate relative to a carrier (2106) to resist back-drive. An actuator consistent with the invention may incorporate an impact mechanism (2616) including a flexible carrier (2618). The carrier (2106) flexes to prevent impact forces at an output gear train (2610, 2612) from coupling to an input gear train (2604, 2606).
Abstract:
A drive device which drives a driven device such as a lift mechanism (8) for lifting a window pane (9), comprising a motor (5) having a rotating shaft (13) and output units (6; 80) connected to the motor, wherein the output units are provided with speed reduction mechanisms (42, 43, 56; 56, 92) decelerating the rotation of the rotating shaft, clutches (21; 71; 81; 200; 300) are installed between the rotating shaft and the speed reduction mechanisms, the clutches allow a rotation to be transmitted from the rotating shaft to the speed reduction mechanisms and prevent the rotation from being transmitted from the speed reduction mechanisms to the rotating shaft, whereby a large load does not apply to the clutches disposed between the rotating shaft and the speed reduction mechanisms and, therefore, a strength required for the clutches can be reduced so as to reduce the size of the clutches.
Abstract:
The invention relates to a cable-controlled window winder, particularly for motor vehicles, comprising a guiding track (10), a catch (20) for a window pane which is positioned movably against the guiding track, and a cable loop (1) that is firmly attached to the catch, connected to a drive unit and guided along the guiding track by reversing elements. According to the invention, the locking element is the base component of the catch (20) positioned movably against the guiding track, said base component of the catch (20) has a supporting area (23), preferably a supporting edge, which by swivelling the catch (20) can be brought into a positive fit with a supporting element (30) provided for along the guiding track (10). In addition, the supporting area (23) of the catch (20) assigned to the supporting element (30) is at a distance from the axis of traction of the cable loop, the supporting element (30) is positioned below the friction element (29) and the window pane (7) is articulated with the catch (20).
