INTERNAL COMBUSTION ENGINE STARTING DEVICE, PARTICULARLY FOR MOTOR VEHICLE, AND ROTATING ELECTRIC MACHINE COMPRISING SUCH DEVICE

摘要

The invention relates to a combustion engine starting device, particularly for a motor vehicle, comprising: - a starter (19) constructed to start the combustion engine, particularly via a ring gear (13); - an electric engine constructed to make the starter rotate; and - a contactor (17) having a longitudinal axis (X) and comprising first and second electrical contact elements (58, 59) constructed to control the electrical supply of the electric motor, enabling the latter to operate sequentially in a first pre-rotation phase and a second full capacity phase, each of the first and second contact elements (58,59) being movable along the longitudinal axis between an open state and a closed state, the first element being supported, particularly with a possibility for sliding, by a movable mounting (70) and by the fact that the second element (59) is guided to move into said mounting of the first element (58).
