    • A rotation rate sensor (100) detecting rotation of the same, comprising a base body (102), a primary oscillator (106) which is maintained in a movable position by a primary suspension device (104) in relation to the base body (102), and a secondary oscillator (114) which is maintained in a movable position in relation to the primary oscillator (106) by means of a secondary suspension device (112) which is separated from the primary suspension device (104). The secondary suspension device (112) is so designed that a movement which can be exerted upon the primary oscillator (106) can be transmitted to the secondary oscillator (11) while no substantial movement of the secondary oscillator (114) caused by the coriolis force can be transmitted back to the primary oscillator (106). Furthermore, the main surfaces of the primary oscillator (106) and the secondary oscillator (114) extend substantially on the same plane whereby the movement of the primary oscillator (106) and/or the secondary oscillator also occurs on this plane.
    • 的旋转速率陀螺仪(100),其用于检测旋转包括基体(102),耦合到其主振荡器悬浮液(104)的主振荡器(106),通过一个装置被可移动地支撑在基体(102)相对,以及辅助振荡器(114) 从主振荡器悬浮液(104)分离的辅助振荡器的悬浮液(112)被保持在主振荡器(106)相对移动。 辅助振荡器悬浮液(112)被形成为使得一个到主振荡器(106)可以被放置成抵靠移动到辅助振荡器(114)可被发送,而由科里奥利力引起的辅助振荡器(114)的运动基本上不(到主振荡器 106)被发送回。 此外,主面延伸的主振荡器(106)和在基本相同的平面上的辅助振荡器(114),并且在该平面内还主振荡器(106)和/或辅助振荡器(114)的移动的位置。
