Description

机动车辆底盘轴的横向板簧组件
技术领域
本发明涉及一种具有横向板簧的机动车辆的底盘轴的横向板簧组件,该横向板簧通过两个外部轴承机构分别支承在车轮架处并且通过两个中央轴承机构支承在机动车辆车身上,其中,这些中央轴承机构分别具有致动器装置,这些致动器装置如以下方式作用在相应的中央轴承机构的轴瓦上:使得支承点在该机动车辆的竖轴和/或横轴方向上是可调整的。
背景技术
横向板簧组件是底盘的一部分。车轮、车轮悬挂系统、避震簧、缓冲器和转向系统都属于底盘。横向板簧组件大体上具有横向板簧,该横向板簧通过两个外部轴承机构分别支承在车轮架处并且通过两个中央轴承机构支承在车身上。通过横向板簧的实施或其影响,能够实现车辆的弹簧刚度、稳定特性和水平调节。在此,该弹簧刚度对机动车辆的弹簧压缩、对车辆的摇摆行为的稳定特性和对地面高度的水平调节具有关键性的作用。
现在,从DE 10 2010 058388 A1中已知,借助于致动器可以在竖轴和横轴的方向上调整中央轴承机构。由此可以调节弹簧刚度和/或对地面高度。
发明内容
但这样的安排具有缺点,即,必须调整整个轴瓦。由此,首先必然存在由构造导致的整个轴承装置的增加的耗费以及与之相关的成本。此外,轴瓦受到磨损,该磨损可能减少使用寿命。
因此,本发明的目的是,提供一种机动车辆的底盘轴的横向板簧组件,该横向板簧组件以简单且成本有效的方式避免上述的这些缺陷。
该目的是通过以下方式来实现,即致动器装置以如下方式形成,在轴瓦位置固定的情况下,支承点在该机动车辆的竖轴和/或横轴方向上能够调整。由此可以通过特别简单的方式实现对底盘特征的适配。
在本发明的一个优选实施方式中,致动器装置形成为在横向方向上在轴瓦上可移动地安排的线性对角调节器。根据调整角度α的设定方式,可以移动在轴瓦中的支承点。
在一个替代性实施方式中,致动器装置形成为在横向方向上在轴瓦上可移动地安排的线性偏心轮调节器。在此,通过对应的偏心轮旋转来调节支承点。在另一个替代性实施方式中,通过安排在轴瓦中的至少两个腔室形成致动器装置,这些腔室通过液压或气动控制来限定期望的支承点。
此外,可以以有利的方式提出,该致动器装置具有扭矩产生装置,其扭矩方向平行于该机动车辆的纵轴走向。同样,也可以设置如下器件,这些器件在机动车辆的竖轴和/或横轴的方向上调整该外部轴承机构。
附图说明
借助于附图更详细地解释本发明,在附图中
图1示出具有示意性展示的横向板簧组件的机动车辆的前视图,以及
图2a、2b、2c示出具有不同致动器装置的本发明横向板簧组件的示意性图示。
具体实施方式
图1在示意性的前视图中示出根据本发明的横向板簧组件2,该横向板簧组件是机动车辆4的(没有进一步展示的)前桥组件的组成部分。两个前轮标有参考符号6、8,这些前轮分别通过已知的方式安排在车轮架10,12处。车轮架10、12尤其通过示意性展示的转向器14、16、18、20与机动车辆4的(未详细展示的)车身相连接。横向板簧组件2的横向板簧22通过中央轴承机构24、26支承在机动车辆4的车身处并且通过外部轴承机构28、30支承在车轮架10、12上。机动车辆4以已知的方式具有竖轴32、横轴34和纵轴36。
图2a、2b和2c现在示出了具有不同致动器装置38、40、42的本发明横向板簧组件2。在此,在图2a和2b中以虚线示出对应的致动器装置38、40的可代替的位置。在此基本示意性地展示横向板簧组件2,其中,仅标记并描述了中央轴承机构24、26。在此,中央轴承机构24、26分别具有轴瓦44、46,横向板簧2被接收在该轴瓦中,并且其中在对应的支承点48、50中进行力导入。
在此,图2a示出了具有致动器装置38的横向板簧组件2,该致动器装置分别形成为横向方向上在轴瓦44、46上可移动地安排的线性对角调节器。由此,支承点48、50能够通过简单的方式支承在对应的中央轴承机构24、26中,而不移动相关联的轴瓦44、46。在此所展示的线性对角调节器38可以具有例如芯轴驱动器,该芯轴驱动器在预设的或可设定的角度α下使对应的支承点48、50偏移。然后可以依据该角度α改变弹簧刚度和对地面高度。
图2b示出了带有附图标记40的致动器装置的第二实施方式,在这种情况下,该致动器装置形成为在横轴34方向上在轴瓦上可移动地安排的偏心轮调节器。支承点48、50借此也能够以简单的方式支承在对应的中央轴承机构24、26中,而不移动相关联的轴瓦44、46。然后可以依据该偏心轮的构造改变弹簧刚度和对地面高度。
最后,图2c示出了带有附图标记42的致动器装置的第三实施方式,其中,在本实施例中在对应的轴瓦44、46中的轴瓦44、46中分别形成四个腔室52、54、56、58,这些腔室通过液压或气动控制来限定期望的支承点48、50。通过适当控制腔室52、54、56、58,支承点48、50可以以简单的方式在竖轴方向32以及横轴方向34上偏移。
应当清楚的是,可以应用多个输入参数,以便在对应的运行情况中设定对应的中央轴承机构24、26的支承点48、50。
此外,这些致动器装置38、40、42具有扭矩产生装置,其扭矩方向平行于该机动车辆的纵轴走向。也可以在机动车辆4的竖轴32和/或横轴34的方向上调整该外部轴承机构。
