Description

驱动装置
技术领域
本发明涉及一种特别是用于汽车活门的驱动装置，它具有和固定的基本部件，特别是汽车车身，或者和可运动的结构部件，特别是汽车活门或者汽车门可连接的壳体管，具有和另一部件，可运动的结构部件或者固定的结构部件个连接的外管（überrohr），具有带有丝杆和设置在丝杆上的丝杆螺母的螺杆传动装置，通过所述螺杆传动装置壳体管和外管轴向可彼此相对运动，具有通过由耦合装置形成的过载保护装置可旋转驱动螺杆传动装置的旋转驱动装置，其中，当超过一定的转矩时可分开它们彼此间的不相对转动连接。 
背景技术
已公开大量这种类型的驱动装置。然而这种驱动的缺陷是，在手动运行时，当连接的控制器失效时，或者在螺杆驱动中建立的耦合脱开时会出现活门位置计算的错误。这样就不再能可靠地起动后舱盖板的最终位置，也就是完全打开的位置，或者完全关闭的位置。 
发明内容
因此本发明的任务是提供一种本文开头所术类型的具有简单和因此成本有利结构的驱动装置，在所述驱动装置中可精确地计算活门的位置。 
根据本发明，这个任务通过下述措施得以完成，即具有多个北极和南极的磁环可旋转运动地设置在传感器元件的附近，其中，和传感器元件共同作用的磁环设置在耦合装置的与丝杆不相对转动连接的部件上，并且传感器元件相对于壳体管位置固定地设置。 
通过这种设置，即使由于驱动装置过负载耦合装置有响应也能检测到汽车活门的位置。 
若霍耳传感器设置在耦合装置的壳体管的内壁上则大大地简化了结构部件的安装。 
附图说明
在附图中示出了本发明的实施例，下面对该实施例进行详细的说明。这些附图是： 
图1：驱动装置的截面图。
图2：图1的驱动装置的放大部分图。 
具体实施方式
在图1中示出的驱动装置具有第一壳体管1，它具胡第一端部2，其中，用底部件3关闭第一端部2。在底部件3上形成螺纹栓4。球形座形式的第一固定装置拧紧到螺纹栓4上。套筒7设置在与第一端部2对置的第二端部6上，在所述套筒中压配合地又设置一个导向套8。然而代替地也可以规定将套筒7和导向导8设计为一体。 
在第一壳体管1的第一端部2的附近设置旋转驱动装置9，所述旋转驱动装置包括电动机10和传动装置11。从电动机10的两个端侧伸出驱动轴12，所述驱动轴在一侧驱动传感器装置13，在另一侧驱动传动装置11。在传动装置11的与电动机10对置的一侧传动器输出轴14朝第二端6方向延伸。耦合装置15在一侧与传动器输出轴14连接，并且在另一侧和螺杆传动装置17的通过导向套8延伸的丝杆16连接。此外，同轴地包围丝杆16的导向管18穿过导向套8延伸。 
在丝杆16上设置丝杆螺母19，所述丝杆螺母可轴向移动，然而在导向管18中不转动的被导向。丝杆螺母19和同轴包围丝杆16的丝杆管20的端部连接，在所述丝杆管中丝杆16在它的与耦合装置15对置的端部借助丝杆导向装置21被导向，以防止丝杆16的径向运动。在与丝杆螺母19对置的端部上螺栓22设置在导向管18上。支撑盘23又套到其上，所述支撑盘用第二固定装置24以另一球形座的形式固定在螺栓22上。 
在导向管18的端部上—所述端部与静止在导向套8中的端部对置—设置导向套25，所述导向套沿轴向方向可移动地对丝杆管20导向。导向管18同轴地被第二壳体管26包围，其中，第二壳体管26用内法兰27支撑在第一壳体管1的第二端部6上，或者支撑在导向套8或者套筒7上。 
第二壳体管26又至少部分地被外管28包围。所述外管28具有内法兰29，所述内法兰靠在支撑盘23上。 
为了支持驱动装置的驶出运动，在导向管18和第二壳体管26，或者外管28之间设置螺旋压力弹簧30，所述压力弹簧支撑在第二壳体管26的内法兰27和外管28的内法兰29上。 
图2示出在图1中示出的驱动装置的部分图，特别是耦合装置15的单个的结构部件。 
所述耦合装置15设置在传动装置11和丝杆轴承31之间。耦合装置15包含内部件32、阻尼元件33、中间部件34、弹簧环35和外部件36。然而也可以有驱动链中的耦合装置的其它位置、耦合的其它结构，例如具有摩擦盘。 
传动器输出轴14借助形状配合连接或者传力连接，例如细齿槽连接，用于传递转矩，和内部件32可插入地连接。内部件32和阻尼元件33、中间部件34形成一种弹性的牙嵌耦合。 
中间部件34通过弹簧环35与外部件36连接。所述弹簧环35在轴向和径向方向固定在外部件36中。 
弹簧环35和中间部件34的连接是通过多个未示出的径向设置的弹簧臂完成的，所述弹簧臂啮合到中间部件34的外壳表面上的径向环绕的波形的或者也未示出的三角形的槽中。 
转矩的传递是通过传动器输出轴14、内部件32、阻尼元件33、中间部件34和弹簧环35传递到耦合装置15的外部件36完成的。 
其中，弹簧环35和中间部件34之间的转矩的传递是通过弹簧臂的端部完成的。从某个转矩起中间部件34相对于弹簧环35旋转，其中，当中间部件继续转动，弹簧臂通过端部首先径向地被向外压，并且紧接着又往回弯曲，其中，端部卡锁到下一个槽中。 
耦合装置15径向和轴向支承在丝杆轴承31中。为此，如图2中可看到的，在外部件上设置具有更小外直径的连接装置37。将丝杠16插入到这个连接装置中。通过细齿槽连接将转矩传递到丝杠16。通过铆钉连接38将丝杠16轴向地固定在外部件36。为了在轴向方向固定耦合装置15，在丝杠轴承31和导向管18之间设置环形盘39。通过环形盘39和绕耦合装置15设置的结构部件绕耦合装置地对在轴向方向起作用的力实施引导。 
外部件36的指向传动装置11方向的端部形成法兰40地向内卷起，并且将支承部件40的盘41保持在一边为内部件32、阻尼部件33、中间部件34和弹簧环35与在另一侧为法兰40之间的一个位置中。整件和盘41相连接的套筒42从盘41继续朝传动装置11方向延伸。在套筒42上设置具有多个北极和南极的磁环43。所述磁环43和传感器元件44共同作用。所述传感器元件设置在印刷电路板45上。所述印制电路板45又设置在耦合装置15的壳体46的内壁上。 
传感器元件44包括至少一个霍耳传感器，然而优选地包括两个具有规定相位偏移的霍耳传感器。虽然在此示出的是一个结构部件，然而也可以使用两个分开的霍耳传感器。 
当在控制装置46未被激活或者在“睡觉”时用手操作汽车的可运动的部件，例如活动门，这时通过霍耳传感器或者两个霍耳传感器的信号，且通过只示出的线路接通控制装置46，通过这一措施，通过与丝杠16不转动地连接的耦合装置15的外部件36和也是不转动地与外部件36连接的磁环43就能感应到丝杠16的旋转运动。
