An electronically actuated and controlled power transmission system includes an electronically controlled inductor (278) which is used as a brake when its reaction member is rotatably locked by the action of pulley (224), inductor (278) moving axially diaphragm (232) relative to back plate (231) of the vehicle starting clutch (230) by varying the friction torque and/or the axial force applied on ball screw mechanism (233/236) by inductor (278) when pulley (224) prevents its rotation. Pulley (225) is driven rotatably by pulley (224) through the action of belt (226), and pulley (225) powers a mechanism transforming its rotation into an alternating axial movement of output rod (285) of gearbox actuator system (280), the alternating axial movement being utilized for the actuation of couplings or synchronizers. When the inductor (278) is electrically energized, rotation of the pulley (225) is prevented through the action of an electronically controlled magnetic friction brake system (223). |
