GEARED MOTOR DRIVE WITH TORQUE SENSING

摘要

A geared motor drive for a vehicle window lifter comprises an electric motor with a motor shaft; a transmission system comprising an input driven by the motor shaft and a drive output; a shock absorber (6) coupling the input to the output of the transmission system; and a sensor for the torque transmitted by the shock absorber. A vehicle window glass lifter incorporating this geared motor drive is also provided. This arrangement reduces the response time before the presence of an object impeding lifting of the window glass is detected.
