摘要： According to the invention, the first end (2a) and the second end (2b) of the pre-tensioned spring (2) are positioned in their pre-tensioned states against a first stop (1a) and a second stop respectively (1b). The rotating body (1) is first rotated at least X times about its longitudinal axis, without the action of external forces, whereby the first end (2a) engages once in a cam wheel (3) during each rotation, said wheel having at least X+1 teeth (3b) and at least one cam (3a) that runs parallel with the teeth (3b). The cam wheel (3) thus rotates one tooth (3b) further with each rotation of the rotating body (1). After at least X continuous rotations, the rotating body (1) is subsequently subjected to pre-tensioning until the cam wheel (3) and its cam (3a) lies against a third stop (6) and the first end (2a) simultaneously engages in the cam wheel (3). The rotation is then continued in order to increase the torque, whereby the first end (2a) remains engaged in the cam wheel (3) and is released from its position against the first stop (1a). The invention also relates to the use of said method in an actuating drive for setting the valve stroke of a motor vehicle.
摘要翻译：根据本发明，预张紧弹簧（2）的第一端（2a）和第二端（2b）分别位于其预张紧状态下抵抗第一止动件（1a）和第二止动件（1b）。旋转体（1）首先在其纵向轴线处至少旋转X次，而不受外力的作用，由此第一端部（2a）在每次旋转期间接合一次在凸轮（3）中，所述车轮具有至少X + 1个齿（3b）和与齿（3b）平行延伸的至少一个凸轮（3a）。因此，随着旋转体（1）的旋转，凸轮（3）进一步旋转一个齿（3b）。在至少X次连续旋转之后，随后对旋转体（1）进行预张紧，直到凸轮（3）及其凸轮（3a）靠在第三挡块（6）上并且第一端部（2a）同时啮合凸轮（3）。然后继续旋转以增加扭矩，由此第一端部（2a）保持接合在凸轮（3）中并从其位置抵靠第一止动件（1a）释放。本发明还涉及所述方法在致动驱动器中用于设定机动车辆的阀行程的用途。
