驱动装置
摘要：
本发明涉及一种驱动装置，尤其为用于车辆箱盖的驱动装置，带有：可与基部件(1)或可与可运动的构件(3)相连接的罩壳管(7)；可与可运动的构件(3)或可与基部件(1)相连接的保护管(14)；具有螺纹芯轴(33)和布置在螺纹芯轴(33)上的芯轴螺母(45)的芯轴传动器，通过该芯轴传动器，罩壳管(7)和保护管(14)轴向上可相对于彼此而运动；以及以可旋转方式驱动芯轴传动器的、包括至少一个电动马达(19)的旋转驱动器(18)，其中，驱动装置(5)包括安全线路(28，28′，28″，28″′)，该安全线路在旋转驱动器(18)无效并且从外部将外力引入到驱动装置(5)中的情况下对旋转驱动器(18)产生制动作用。
摘要（英）：

A driving device for a hatch in a vehicle, with a housing tube (7) connected to a base part (1) or to a movable structural component part (3), a protective tube (14) connected to the movable structural component part (3) or to the base part (1), a spindle drive having a threaded spindle (33) and a spindle nut (45) arranged on the threaded spindle (33) by which the housing tube (7) and the protective tube (14) are movable axially relative to one another. A rotary drive (18) drives the spindle drive in rotation includes at least one electric motor (19). The driving device (5) has safety circuits (28,28',28'',28''') that causes a braking effect on the rotary drive (18) when the rotary drive (18) is deactivated and when extraneous forces are introduced into the driving device (5) from the outside.
