Screw drive for closure element of motor vehicle
The invention relates to a spindle drive for a closure element (3) of a motor vehicle, having a spindle-spindle-nut drive (4) for carrying out a linear drive movement, a spindle-side drive section (5) having a spindle (4a) and a spindle-nut-side drive section (8) having a spindle nut (4b), the spindle-side drive section (5) having a spindle (4a) and the spindle-nut-side drive section (8) having a spindle nut (4b), a screw drive housing (13) having an inner tube (14) and an outer tube (15) is provided, the inner tube (14) running telescopically in the outer tube (15), the outer tube (15) or the inner tube (14) having an annular sealing arrangement (20) surrounding about a geometric screw axis (11), which sealing arrangement slides along a respective other tube of the screw drive housing (13) during a drive movement. According to the invention, the sealing arrangement (20) has a first axial annular section (21) and a second axial annular section (22) which adjoins the first axial annular section in the axial direction with respect to the geometric spindle axis (11) and which is movably connected to the first axial annular section (21), the second axial annular section (22) is radially displaceable relative to the first axial annular section (21) during a drive movement between a sealing position, in which the sealing effect of the sealing arrangement (20) is maximized, and a raised position, in which the sealing effect of the sealing arrangement (20) is lower than in the sealing position.
本发明涉及一种用于机动车辆的封闭元件(3)的螺杆驱动装置，该螺杆驱动装置具有用于执行线性驱动运动的螺杆‑螺杆螺母传动机构(4)，其中，螺杆侧的驱动区段(5)具有螺杆(4a)，并且螺杆螺母侧的驱动区段(8)具有螺杆螺母(4b)，其中，设置了具有内管(14)和外管(15)的螺杆驱动装置壳体(13)，其中，内管(14)伸缩式地在外管(15)中运行，其中，外管(15)或内管(14)具有关于几何螺杆轴线(11)环绕的环形的密封布置结构(20)，在驱动运动期间该密封布置结构沿着螺杆驱动装置壳体(13)的相应的其他管滑动。提出了，密封布置结构(20)具有第一轴向环形区段(21)以及关于几何螺杆轴线(11)沿轴向与该第一轴向环形区段邻近的第二轴向环形区段(22)，该第二轴向环形区段能运动地与第一轴向环形区段(21)连接，并且在驱动运动时第二轴向环形区段(22)能够相对于第一轴向环形区段(21)在密封位置与抬起位置之间沿径向移位，在该密封位置中密封布置结构(20)的密封效果最大，在该抬起位置中密封布置结构(20)的密封效果比在密封位置中要低。
