ABSTRACT:
A disengageable transmission device is provided in which a driving pinion is used to selectively drive a driven wheel via a wheel train mounted on pivotal lever. The fulcrum of the pivotal lever is positioned so as to minimize the rotational torque effects on the wheel train lever of the contact between the driving pinion and the wheel train and of the contact between the driven wheel and the wheel train. An energy escapement control device is also provided and the torque effects of this device on the wheel train lever are also limited by the positioning of the fulcrum of the lever.
