Device for reversibly converting linear movements into rotational movements and for converting rotational movements into electrical energy, and vice versa. The device has a central rail and a support element which surrounds the central rail, wherein the support element is arranged so as to be displaceable relative to the central rail in the longitudinal direction of the central rail in linear movements. A plurality of rolling bodies which are in contact with the central rail are rotatably mounted in the support element. The rolling bodies carry out rotational movements during the linear movements of the support element relative to the central rail through interaction with the central rail. The linear movements are also coupled to the drive or output of an electric machine. In this context, the rolling bodies to which elastic preloading forces are applied are arranged in such a way that the central rail is mounted substantially free of play under pressure, wherein the preloading forces cancel one another out and are generated by means of elastically shaped securing clips on the support element. The rotational movements of at least one rolling body form here the drive or output of the electric machine. |
