Some of the modules correspond to a gear motor C which generates the drive force, provided with a sliding support with fastening screw K and shaft, on which a pulley G is coupled, via which the retraction of the bolts is achieved, and also a friction clutch E which transmits the direction of rotation to the pulley. The same shaft of the gear motor includes a friction clutch E which transmits drive force to the rest of the reducing pinions and chains of the unit, and a primary pinion receiving the rotary action which provides the power for actuation of the door, transported from the displaceable pinion I to the functional pinion B via the chain A. The composition facilitates the addition, substitution or removal of modules at the base. <IMAGE> |
