Abstract
(EN)
An electric starter, comprising a starter motor (24), a power transmission mechanism (22), and a clutch mechanism (26). The power transmission mechanism comprises a power transmission assembly and an energy storage assembly. The power transmission assembly is constructed to comprise a power transmission wheel, the power transmission wheel being directly or indirectly driven by the motor. The energy storage assembly is constructed as a volute spring (222). Both free ends of the volute spring are respectively connected to the power transmission wheel and the clutch mechanism. The power transmission wheel is constructed to have a cavity (2264) for receiving the volute spring, the cavity having an opening. The power transmission mechanism further comprises a volute spring constraining member. The volute spring constraining member forms constraint for the volute spring received in the cavity, the constraint making the volute spring be unable to disengage from the cavity. The present invention also relates to an internal combustion engine having the electric starter.

Démarreur électrique, comprenant un moteur de démarreur (24), un mécanisme de transmission de puissance (22) et un mécanisme d'embrayage (26). Le mécanisme de transmission de puissance comprend un ensemble de transmission de puissance et un ensemble de stockage d'énergie. L'ensemble de transmission de puissance est conçu pour comprendre une roue de transmission de puissance, cette dernière étant directement ou indirectement entraînée par le moteur. L'ensemble de stockage d'énergie est conçu sous la forme d'un ressort en volute (222). Les deux extrémités libres du ressort en volute sont respectivement reliées à la roue de transmission de puissance et au mécanisme d'embrayage. La roue de transmission de puissance est conçue de façon à présenter une cavité (2264) destinée à recevoir le ressort en volute, la cavité comportant une ouverture. Le mécanisme de transmission de puissance comprend en outre un élément de contrainte de ressort en volute. L'élément de contrainte de ressort en volute forme une contrainte pour le ressort de volute reçu dans la cavité, la contrainte empêchant le ressort en volute de se dégager de la cavité. La présente invention concerne également un moteur à combustion interne équipé dudit démarreur électrique.
