TRANSMISSION DRIVE UNIT COMPRISING A LOAD TORQUE LOCK

摘要

The invention relates to a transmission drive unit (10), especially a window winding drive, comprising an electric motor (14) which drives a transmission (30), and a load torque lock (44) which locks the torque (86) introduced by a coupling element (42) on the output side. The load torque lock (44) comprises a coil spring (54) which is arranged on/in a rotationally fixed shaft (50, 52) and engages in a transmission toothed wheel (40) driven, on the drive side, by a rotor shaft (16) of the electric motor (14).
