ABSTRACT:
An electrical window lift drive especially for use in a motor vehicle, includes a drive housing, an electric motor attached to the housing having a shaft extending into the interior of the housing. A worm gear is mounted on the motor shaft for rotation thereby. A worm wheel is mounted for independent rotation coaxially with respect to a first portion of a bearing shaft inside the housing on a member intermediate the bearing shaft and the wheel. The bearing shaft is supported in the housing on both sides of the worm wheel and extends transversely of the motor shaft. The worm wheel meshes with and is driven by the worm gear. A drive member is mounted coaxially with respect to a second portion of the bearing shaft, and means are provided intermediate the worm gear and the drive member for transferring rotary motion of the worm gear to the drive member.
