Description

用于机动车的车桥导向臂
技术领域
本发明涉及一种用于机动车的车桥导向臂/车轮悬挂臂，该车桥导向臂具有车身侧的连接件和车轮侧的连接件，其中，所述连接件通过一杆件相互连接，该杆件包括金属杆和由塑料制成的增强外套。
背景技术
文献DE 38 27 854 C1公开了一种用于机动车的车轮导向系统，该车轮导向系统具有转向横拉杆和管形式的横向控制臂，还具有插入管中的用于传递拉力的传递杆，该传递杆在一端通过力锁合或形锁合的支架保持在管中和在另一端从管端部突出。在支架与管端部之间的传递杆具有预定破坏位置且在预定破坏位置与管端部之间具有凸肩，其中，管在凸肩与管端部之间配设有管变窄部，该管变窄部构成在预定破坏位置破坏时用于凸肩的挡块，以便阻止结构件完全分离。在车轮导向系统中，转向横拉杆或横向控制臂的拉力通过传递杆传递。在拉力超出特定极限负荷时，预定破坏位置破坏。随后，传递杆在持续的拉力负荷下以其凸肩移动直至管变窄部，由此能够在传递杆与管之间继续传递拉力。然而装置的纵向变化引起车轮导向系统的这样形成的几何形状变化，使得每个驾驶员都通过机动车的行驶行为得到清楚的预先警告。
DE 10 2006 058 377 B4涉及一种用于结构性增强飞机的机身结构的萨梅尔杆(Samerstange)，具有柄部和在两侧布置在柄部上的、用于将萨梅尔杆连接到机身结构上的孔。纯碰撞负荷在碰撞网络中非常重量有利地通过塑料绳拦截。由于孔借助于通过多个增强纤维形成的增强布置结构连接，因此萨梅尔杆在所有飞行状态连同事故情况(碰撞情况)下都具有足够的机械承受力。增强布置结构可以设计为外套，该外套基本上完全包围柄部和具有布置在其上的孔的螺纹杆。
发明内容
本发明的目的是，提出一种车桥导向臂，该车桥导向臂具有能量吸收功能和在拉力与压力下的显示出的损坏机质，其中，利用通过延展性材料连接的车桥导向臂可确保足够的剩余使用寿命，该剩余使用寿命能够使得用户能到达维修车间。
此外，根据本发明的车桥导向臂的特征在于：金属杆由延展性材料制成且在连接件处锚固在外套中，所述增强外套由脆性材料制成且在连接件之间的一纵向位置处具有预定破坏位置。
因此，车桥导向臂由作为芯部的延展性金属杆和由脆性材料制成的增强外套组成，该增强外套用于实现在正常运行中必要的刚性和强度。金属杆这样设计：使得该金属杆在外部的增强外套由于滥用事件而失效时变成塑性的且被缓慢地从导向臂中拉出。因此，车桥导向臂可能折弯/开裂(压力)或改变其长度(拉力)，这例如通过使方向盘歪斜而向用户指示出，不会发生破坏部分的分离。
在根据本发明的车桥导向臂中，使金属杆相对于增强外套彼此拉开的力可以以简单的方式通过金属杆的材料和金属杆的几何尺寸进行调节。此外有利的是，车桥导向臂的塑性变形导致能量降低。
根据本发明的车桥导向臂的一个有利的设计方案的特征在于增强外套由纤维增强的塑料制成，优选由碳纤维增强塑料(CFK)制成。
根据本发明的车桥导向臂的另一个有利的设计方案的特征在于，金属杆的周长或者说周向尺寸从其中一个连接件处的锚固部向预定破坏位置增大并且从该预定破坏位置向另一个连接件减小。因此可以以有利的方式调节用于使得车桥导向臂彼此拉开的力或金属杆的延展性。
根据本发明的车桥导向臂的另一个有利的设计方案的特征在于，使金属杆相对于增强外套彼此拉开的力是通过金属杆和增强外套的材料的摩擦副调节的，其中特别地，所述力能在通过金属杆和/或增强外套上的粗糙表面所引起的较大的力、通过金属杆和/或增强外套上的抛光表面所引起的较小的力和通过在金属杆和/或增强外套上的表面上使用油所引起的最小的力之间进行调节。换句话说，所述力可以根据特定的应用情况在一个大的范围内进行调节。
根据本发明的车桥导向臂的另一个有利的设计方案的特征在于，金属杆的锚固部通过所形成的金属杆增厚部构成，其中，以简单的方式通过形锁合阻止金属杆完全从增强外套中滑出。
根据本发明的车桥导向臂的另一个有利的设计方案的特征在于，金属杆设计为空心体，该空心体的尺寸设计为使该空心体在破坏应力下收缩，从而失去与增强外套的连接，其中，在金属杆与增强外套之间的摩擦消失，从而可以使得两个结构件容易地彼此拉开。
附图说明
本发明的其它优点、特征和应用可能性由下面的说明结合附图中所示的实施例得出。
在说明书、权利要求和附图中使用在下面的附图标记列表中所使用的术语和对应的附图标记。图中示出：
图1示出根据本发明的车桥导向臂的实施方式的剖视图。
具体实施方式
根据图1，根据本发明的车桥导向臂2具有车身侧的连接件4和车轮侧的连接件6，这两个连接件4、6通过一杆件8相互连接，该杆件包括金属杆10和增强外套12。金属杆10由延展性材料制成且在连接件4、6附近通过金属杆10的形成的增厚部被锚固在增强外套12中。
增强外套12用于，在正常运行中确保车桥导向臂2的必要的刚性和强度。为此，增强外套12由脆性材料制成，特别由碳纤维增强塑料(CFK外套)制成。最后，增强外套12具有预定破坏位置20，根据本发明的车桥导向臂2在过载的情况下在该预定破坏位置处破坏。
在车桥导向臂2的所示实施例中，金属杆10的周长(或者说周向尺寸)从连接件4处的锚固部或增厚部14向预定破坏位置20增大，且从预定破坏位置20向车轮侧的连接件6减小。另选地也可能选择金属杆10的周长的反向走向，即例如将金属杆10的周长最小的位置用作金属杆10的预定破坏位置20。
使金属杆10相对于增强外套12彼此拉开的力能够以不同的方式——特别是通过金属杆10和增强外套12的材料的摩擦副——进行调节。为此，该力能够在通过金属杆10和/或增强外套12上的粗糙表面所引起的较大的力、通过金属杆10和/或增强外套12上的抛光表面所引起的较小的力和通过在金属杆10和/或增强外套12上的表面处使用油所引起的最小的力之间进行调节。
同样出于对在使得结构件彼此拉开时力调节的考虑，金属杆10可以设计为空心体(未示出)，该空心体在破坏应力的情况下收缩、因此失去与增强外套12的连接。
