将车窗调节器的滑轮安装至塑性轨道的方法及获得的组件
Abstract:
本发明涉及用于将车窗调节器的滑轮固定至塑性轨道的方法以及用于车窗调节器的组件，该组件包括：滑轮、塑性轨道和螺栓，该螺栓用于将滑轮在轴向方向上固定至塑性轨道，但允许滑轮绕螺栓旋转。螺栓包括螺纹轴、杆部、肩部、环形槽以及头部。组件还包括具有中心孔的金属片，使得当将金属片插入穿过之前引入到塑性轨道的通孔中的螺栓的螺纹轴时，该金属片部分地与肩部的支承基部接触，并且部分地与塑性轨道接触，使得当金属片被轴向地压靠于支承基部时，金属片的孔的直径变得小于螺纹轴的直径，并且进入螺栓的环形槽。该组件还包括凹部，其位于塑性轨道的第二侧部中以用于容置金属片，凹部的内部形状是非圆形形状以阻止金属片绕螺栓旋转。
Abstract(English):

The invention provides a method for mounting a pulley of a window regulator to a plastic rail and an assembly for the window regulator. The assembly comprises a pulley, a plastic rail and a bolt for fixing the pulley to the plastic rail in an axial direction but allowing the rotation of the pulley around the bolt. The bolt comprises a threaded shaft, a shank, a shoulder, an annular groove, and a head. The assembly further comprises a metal sheet with a central hole, such that when inserting the metal sheet through the threaded shaft of the bolt, which has been previously introduced in a through hole of the plastic rail, the metal sheet contacts partially with an support base of the shoulder and partially with the plastic rail such that when the metal sheet is axially compressed against thesupport base, the diameter of the hole of the metal sheet becomes smaller than the diameter of the threaded shaft and gets in the annular groove of the bolt. The assembly further comprising a recessin a second side of the plastic rail for housing the metal sheet, the internal shape of the recess being a non-circular shape to stop the metal sheet from rotating around the bolt.
