Spindle drive for closure element of motor vehicle
The invention relates to a spindle drive for a closure element (2) of a motor vehicle, said spindle drive comprising a drive unit (3) and a spindle-spindle nut drive (6) which is drivingly connected downstream of the drive unit (3) and which has a spindle (7) and a spindle nut (8) for generating a drive movement, the spindle drive (1) has two drive sections (9, 10) having a drive joint (11, 12) for outputting a drive movement, the drive joints (11, 12) being adjustable relative to each other by means of the drive unit (3) between an in-position and an out-position along a geometric drive longitudinal axis (13) over an adjustment path (s), and the drive joints (11, 12) being movable relative to each other by means of the drive unit (3) along the geometric drive longitudinal axis (13). The spindle (7) is associated with one of the drive sections (10) and is axially fixed relative to the drive connection (12) of this drive section (10), and wherein the spindle nut (8) is associated with the other drive section (9) and is axially fixed relative to the drive connection (11) of this drive section (9). According to the invention, the spindle drive (1) has a support sleeve (16), which radially surrounds the spindle nut (8) in the extended state and which is supported in such a way that the support sleeve moves axially relative to the two drive connections (11, 12) during a drive movement from the extended state to the extended state.
本发明涉及一种用于机动车辆的封闭元件（2）的主轴驱动器，其中，主轴驱动器具有驱动单元（3）和在驱动技术上接在驱动单元（3）后方的主轴‑主轴螺母传动机构（6），所述主轴‑主轴螺母传动机构带有主轴（7）和主轴螺母（8）以用于产生驱动运动，其中，主轴驱动器（1）具有带有用于输出驱动运动的各一个驱动接头（11、12）的两个驱动区段（9、10），其中，驱动接头（11、12）能够借助驱动单元（3）相对于彼此在移入状态与移出状态之间在调整行程（s）上沿着几何的驱动纵轴线（13）调整，其中，主轴（7）配设给其中一个驱动区段（10）并且相对这个驱动区段（10）的驱动接头（12）轴向固定，其中，主轴螺母（8）配设给另一个驱动区段（9）并且相对这个驱动区段（9）的驱动接头（11）轴向固定。提出了，主轴驱动器（1）具有支撑套筒（16），所述支撑套筒在移出状态下沿径向包围主轴螺母（8）并且所述支撑套筒如此得到支承，使得所述支撑套筒在从移入状态到移出状态的驱动运动中相对于这两个驱动接头（11、12）沿轴向移动。
