    • The invention relates to a starter (1) for a combustion engine and to the associated method. The starter comprises an electric motor in which, when electrically powered, it drives the rotation of its rotor shaft about its longitudinal axis in a direction of rotation for starting. The starter further comprises a drive shaft that can be rotationally coupled to the rotor shaft, a pinion (13) mounted on the drive shaft and movable in a translational movement between a rest position and an active position by a movement system. Furthermore, the starter comprises a coupling system (30) that couples a rotary movement in one direction of rotation of the rotor shaft (5) to the pinion (13), the coupling system (30) being able to move from an uncoupled state into a coupled state and vice versa, in which, in the coupled state, the rotor shaft (5) is firmly attached to the pinion (13) in the starting direction of rotation, and in which in the uncoupled state, the pinion (13) is disconnected from the rotor shaft (5) in both directions of rotation. The starter further comprises a movement system for moving the pinion (13) from its rest position into the active position and vice versa, moving the coupling system (30) into the uncoupled state as it moves the pinion into the active position.
    • 本发明涉及一种用于内燃机的起动器(1)及其相关方法。 起动器包括电动机,其中当电动时,其驱动其转子轴绕其纵向轴线在旋转方向上的旋转以用于起动。 起动器还包括可旋转地联接到转子轴的驱动轴,安装在驱动轴上的小齿轮(13),并通过移动系统在静止位置和活动位置之间的平移运动中移动。 此外,起动器包括联接系统(30),其将转子轴(5)的一个旋转方向上的旋转运动耦合到小齿轮(13),联接系统(30)能够从非耦合状态移动到 耦合状态,反之亦然,其中,在联接状态下,转子轴(5)沿着旋转的起始方向牢固地附接到小齿轮(13),并且在非耦合状态下,小齿轮(13) 在两个旋转方向上与转子轴(5)断开。 起动器还包括用于将小齿轮(13)从其静止位置移动到活动位置并且反之亦然的运动系统,当联接系统(30)将小齿轮移动到主动位置时,使联接系统(30)移动到非耦合状态。
