Description

刮水片
技术领域
本发明涉及一种刮水片。
背景技术
在DE 10025710A1中公开了一种用于汽车雨刷的刮水片,该刮水片具有一个带顶部嵌条(Kopfleiste)和通过翻转连接片连接在顶部嵌条上的刮水条的雨刷胶条。顶部嵌条具有两个侧面的纵槽,在纵槽中装入弹簧条。这些弹簧条作为有弹性的支承元件使用,这样就不需要其它的夹套系统。更确切地说刮水片通过大致设置在中间的连接元件与刮水臂铰接连接在一起。在端部,部分在侧面从纵槽突出的刮水条通过桥接件保持在一起。该桥接件具有带有平行于弹簧条延伸的向外指向的支架的侧部,该支架被固定在弹簧条上,例如通过焊接。处于侧部之间的中部跨接顶部嵌条的防护板,该防护板向上限制所述纵槽。在中部成型了夹板,该夹板沿刮水片的纵向延伸并以成型在其自由端部上的卡爪在安装时被压进雨刷胶条的防护板内。由此,桥接件固定了弹簧条相互之间的位置以及弹簧条相对于雨刷胶条的位置。桥接件由保护罩盖住。
发明内容
按本发明,在弹簧条中在其端部区域中设置有孔,侧部的一部分穿过这些孔并在弹簧条的背对中部的一侧塑性变形,以便桥接件与弹簧条牢固地连接在一起。塑性变形优选地通过冷变形实现,例如通过顶锻、模压、铆合、开槽、弯曲或者类似的方法。由于不需要使用高温,弹簧条的弹簧钢和雨刷胶条都不会受到负面影响或者损害。此外,制造和安装都不需要复杂的装置和保持装置。
弹簧条中的孔可以具有圆形的周向轮廓或者是具有矩形的或倒圆的周向轮廓的长孔。与圆形孔相比,长孔的优点是防止桥接件相对于弹簧条扭转。桥接件的侧部的通过弹簧条的孔被插入的一部分基本上具有与孔相同的横截面轮廓。它们可以在冲压和弯曲方法中作为凸耳成型在桥接件上,或者通过挤压和深冲作为销子由侧部的材料成形。在弹簧条的背对桥接件的一侧上,使凸耳或者说销子的突出的一部分相应地塑性变形。如果销子具有圆形的或半圆形的周向轮廓,那么除了其它的变形方法外还可以使用摆动(Taumeln)。
桥接件的侧部的通过弹簧条的孔伸出的并用于固定桥接件的一部分也可以在安装时成形,方法是使桥接件的侧部以平行于弹簧条延伸的向外指向的支架在孔的区域内紧贴在弹簧条的表面上并且通过用冲模压制或者深冲由支架的材料中通过孔形成销子并且该销子在另一侧上展宽。
附图说明
由以下附图说明中获得其它的优点。附图中示出了本发明的实施例。附图、说明书和权利要求书包括了大量的特征组合。本领域的技术人员也按照目的单个地考虑这些特征并归纳出其它有意义的组合。
其中:
图1是按本发明的刮水片的一个端部的透视图,
图2是相应于图1中线条II-II的横截面;
图3是图1的变型方案,
图4是相应于图3中线条IV-IV的横截面,
图5是用于按本发明的刮水片的桥接件的透视图,
图6是具有按图3的桥接件的类似于图4的横截面,
图7是图1的变型方案,
图8是相应于图7中线条VIII-VIII的横截面。
具体实施方式
在说明书中,具有相同功能的部件使用相同的附图标记。刮水片10具有带雨刷唇14的雨刷胶条12,该雨刷唇14通过翻转连接片16与顶部嵌条18连接在一起。在顶部嵌条18中设置有侧面的纵槽20,在所述纵槽20中装入弹簧条34。纵槽20向上通过防护板22受到限制。
弹簧条34在侧面从纵槽20中伸出一段距离并在其端部通过桥接件24相互连接。桥接件24具有一个中部26和两个侧部28,所述侧部28被固定在弹簧条34上。此外,弹簧条34具有孔36,侧部28的销子38被插入这些孔中。在按图1和图2的实施例中,销子38在桥接件24安装前或者在桥接件安装时通过挤压和深冲制成。为此所需的材料从侧部28中取得,这样一来在侧部28的与销子对置的一侧上形成了凹穴40。
侧部28具有平行于弹簧条34延伸的支架52,该支架52向外指向并以支承面46紧贴在弹簧条34的上表面上。从支架52出发,销子38通过孔36伸出并在另一侧塑性变形。在按图2的实施例中,销子38的这个端部被展宽并用铆钉钉紧,这样就在弹簧条34的下表面上形成凸缘42。如从图2可以看出,孔36优选地呈圆锥形状朝支架52逐渐变小。作为替代或补充,孔36的边缘也可以优选地进行倒棱。由此避免了缺口应力,并且在变形过程中有利于材料流。通过桥接件24,两个弹簧条34相互之间的位置得到了固定。
桥接件24的中部26可以具有夹板30,该夹板30在刮水片10的纵向上延伸并在其自由端部上具有卡爪32。在安装时,卡爪32被压进雨刷胶条12的防护板22中。由此附加地固定了弹簧条34相对于雨刷胶条12的位置。
按图3和图4的实施例与按图1和图2的实施例的不同之处在于具有长孔形式的孔36,所述孔36可以具有矩形的周向轮廓或者倒圆的周向轮廓。销子38在安装过程中制成,方法是将桥接件24以其向外指向的支架52安置在弹簧条34的上侧。材料通过冲模从孔36中压出,与在深冲时相似。在弹簧条34的下侧,使材料塑性变形,例如通过卷边、模压、铆合等等。在这里孔36也优选地略微呈圆锥形并且/或者在其边缘进行倒棱。通过长孔,桥接件24不会相对于弹簧条34转动。
在按图5和图6的实施例中,桥接件24的侧部28具有成型的凸耳44,该凸耳44用弯曲和冲压方法制成。凸耳44通过孔36被插入并且在其自由端部上相应地塑性变形,例如铆合,这样就在弹簧条34的下侧形成了铆钉头48。在弹簧条34的上侧,桥接件24以它的支承面46紧紧地贴靠在弹簧条34上。
在按图7和图8的变型方案中,桥接件24具有侧部28,该侧部28具有平行于弹簧条34延伸的向外指向的支架52。一个中间的保持部分54通过切口50从支架52中分开并弯曲到垂直于弹簧条34的方向,这样保持部分54就可以通过孔36被插入弹簧条34中。它们在另一侧上向外弯曲。于是弹簧条34就被牢固地保持在弯曲的端部56和支架52的支承面46之间。但是也可以通过铆合、顶锻、开槽或其它类似的方法使保持部分54在其自由端部上塑性变形。
