Spindle drive for closure element of motor vehicle
The invention relates to a spindle drive for a closure element (2) of a motor vehicle (3), comprising a drive unit (4) and a spindle-spindle nut transmission (5) which is connected downstream and has a spindle (6), the spindle drive (1) having drive connections (13, 14) for deriving the drive movement, which connections can be adjusted relative to one another, a first drive connection (13) is axially fixedly connected to the spindle guide tube (8), a second drive connection (14) is axially fixedly connected to the spindle (6), and a drive spring (15) is provided for generating a drive movement along the drive longitudinal axis (9), said drive spring acting on the drive connections (13, 14), the spindle guide tube (8) has a first outer diameter (a) along at least one axial section. According to the invention, the spindle guide tube (8) has a tube end section (17) on the side thereof facing the first drive connection (13), which tube end section (17) has a tube end edge (18), which tube end section (17) widens radially over at least part of the circumference thereof such that the tube end edge (18) has an outer end edge radius (e) that is greater than the first outer diameter (a), and the widened pipe end section (17) locks the drive spring (15) against a movement along the drive longitudinal axis (9).
本发明涉及一种用于机动车（3）的封闭元件（2）的主轴驱动器，其中，驱动单元（4）和连接在下游的具有主轴（6）的主轴‑主轴螺母‑传动机构（5），所述主轴驱动器（1）具有用于导出所述驱动运动的驱动接口（13、14），所述驱动接口能够相对彼此调节，其中，第一驱动接口（13）轴向固定地与所述主轴引导管（8）连接，其中，第二驱动接口（14）轴向固定地与所述主轴（6）连接，其中，设置用于产生沿着所述驱动纵轴线（9）的驱动运动的驱动弹簧（15），所述驱动弹簧作用到所述驱动接口（13、14）上，其中，所述主轴引导管（8）沿着至少一个轴向区段具有第一外径（a）。提出的是，所述主轴引导管（8）在其面向所述第一驱动接口（13）的一侧上具有管端区段（17），所述管端区段（17）具有管端边缘（18），所述管端区段（17）在其圆周的至少一部分上径向扩宽，使得所述管端边缘（18）具有大于所述第一外径（a）的外端边缘半径（e），并且所述扩宽的管端区段（17）锁定所述驱动弹簧（15）以防沿着所述驱动纵轴线（9）运动。
