摘要

Transmission ratio selector device between pulleys of a speed variator which, being such a speed variator, of the type in which the pulleys are of variable width in function of which one of the plates is axially slidable on the axis of rotation, is essentially characterized in that the separation between the fixed and movable plate of one of the pulleys, preferably the motor is regulated through a rotary knob which is connected by radial pin, even bushing externally threaded to a nut fixed to the casing of the corresponding casing. Controls, whose bushing pulls in its displacements to the moving plate of the pulley, having provided means to fix a selected position, consisting of a screw that axially crosses the rotary knob and another concentric body and internal to it, whose internal body serves as track or support for the rotary knob, (Machine-translation by Google Translate, not legally binding)
