    • An electric universal drive, comprising a revolving or linearly movable output member (1), further comprising at least two sets of actuators arranged in dedicated carriers (3), in particular piezo actuators (4, 5, 6), which act on a base (7) supported on the output member (1), wherein the at least two sets of actuators alternately press the respectively associated base (7) against the output member (1) and deflect the output member (1) in the direction of the output movement in the spirit of a high-frequency step sequence, wherein furthermore the carriers (3) of the actuator sets are connected in a semi-rigid manner at a location that is laterally offset with respect to the base (7) parallel to the direction of movement of the output member (1), and the carriers (3) are supported on a stator preloaded by a preloading element (9) in a spring-elastic manner with respect to the output member (1), wherein between the preloading element (9) and the respective carrier (3) a toggle lever mechanism (10) having a first toggle lever (24) and transmitting the preloading force is arranged, which engages on the carrier (3) at a location that is offset to the other side compared to the carrier connecting location with respect to the base (7) parallel to the direction of movement of the output member (1), the toggle lever mechanism has a second toggle lever (25), which is arranged between the preloading element (9) and a counter bearing (27) fixed to the stator, wherein the toggle lever mechanism (10) is associated with an operating actuator (28), which is connected to the toggle links of the two toggle levers (24, 25) by way of a coupling member (29), and the arrangement of the toggle lever mechanism (10) is such that the second toggle lever (25) is collapsed when the first toggle lever (24) is extended, and vice versa, and the operating actuator (28) is used to jointly switch the two toggle levers (24, 25) between the extended position and the collapsed position.
    • 通用电动驱动器,具有旋转或线性移动的输出件(1),并且进一步被安排与每个在其自己的支持的至少两个(3)组的致动器,特别是压电致动器(4,5,6),每个一方面(在汽提部 1)支脚(7)的动作,其中,所述至少两组致动器的交替的各相关的脚(7)推压(在分别输出部分1)和(在部件1的驱动器的输出运动)的方向上产生的高频步骤序列的有义 定向,进一步地,其中所述支撑台是在一个相对于基部(7)平行于输出构件的移动方向连接在所述致动器(1)根据在半刚性的方式和一侧移动的位置的载体(3)(3)在每种情况下通过偏置构件(9 )被弹性地支撑在偏置在定子上的从动部件(1)上,其中,在偏置部件(9)和相应的载体(3)之间,d 即偏置力传递肘节机构(10),包括第一肘杆(24)布置,其由偏移相对于载体联合另一方面的相对(7)平行地接合到所述基部到所述输出构件(1)的运动方向,网站上的支撑件(3), 肘节机构包括一个设置在所述偏置构件(9)和一个定子固定的支座(27),肘节机构(10)之间的第二肘杆(25)是一个Betätigungsaktor(28)相关联,通过连接部件(29)与所述膝关节 既是肘杆(24,25)相连,并制成以使得如果所述第一肘杆(24)被拉伸时,第二肘杆(25)铰接在Kniehebelmechanimus(10)的布置,并且反之亦然,并且Betätigungsaktor( 28),用于在延伸位置和Einknickstellung之间的两个肘杆(24,25)的共同切换。
