Problems solved by technology

In particular, today, for this reason, electric cable window lift systems on the front and rear doors are offered as units with electric motors with a possible output of 20 W, however, this fact has a drawback: at the rear doors Excessive structural volume must be provided which is not actually necessary
However, the relatively high demands on adjusting the front windows, especially the relatively complex window guidance with low mechanical efficiency etc. hinder the achievement of this goal

Embodiment Construction

[0037] FIG. 1 shows a gear set according to the invention in a cross-sectional view. As shown in FIG. 1 , a turbine 10 is accommodated in a gearbox part 6 consisting of a case bottom 7 and side walls 8 extending perpendicular to the case bottom 7 . Protruding perpendicularly from the bottom 7 is a pivot pin 9 which can be designed as a metal or plastic pin and is firmly connected to the bottom 7 . Pivot pin 9 acts as turbine 10 with image 3 The axis of rotation of the cable drum shown in . The drive shaft of the electric motor extends through a cylindrical hole in the left edge of the gearbox part 6 and has a drive worm 15 meshing with the worm gear 10 at the front end of the drive shaft. The worm gear 10 and the drive worm 15 form a worm gear whose gear ratio is defined by the teeth 11 of the drive worm 15 and the worm gear 10 .

[0038] According to the present invention, the gear ratio of the worm gear is in the range from about 1:38 to about 1:55, preferably in the ran...

Abstract

The window drive system has an electric motor with a worm engaging the teeth (11) of a worm wheel (10). The wheel has a central aperture (16) for a support shaft and apertures (13,14) accommodating drive claws (19,20) on a worm wheel (17). - The wheel has a flange (23), a ribbed drum (18) and a curved portion (28) leading to a channel (27) with an end chamber (26) to accommodate the enlarged end of the window winding cable. The diameter of the drum may be between 22 and 30 mm and the worm gear reduction ratio may be between 1:38 and 1:51.

Description

technical field [0001] The present invention relates to a motor vehicle cable window lift system gear set for manual or engine driven operation, and to an engine driven gear set. Background technique [0002] The numerous requirements placed on engine-driven gear sets for motor vehicle window lift systems by cable actually imply a relatively narrow range of parameters in terms of structural design. Specifically, the following constraints must be taken into account in the structural design: the output power of the electric motor used for electric drive; the available on-board power of the motor vehicle which has an influence on the maximum output power; The friction force brought by the structural design of the window lifting system; at the same time, it is aimed at the structural design of the window lifting system on the front door of the motor vehicle and the window lifting system on the rear door of the motor vehicle; adjusting the maximum stroke required by the window; ...
