Description

用于机动车的副车架
技术领域
本发明涉及一种用于机动车的前部车体或后部车体的副车架，该副车架具有两个在车辆横向方向上彼此间隔开并通过至少一个横梁相互连接的纵梁，其中，该副车架具有用于提高扭转刚度的加固结构，用于无接触地传递能量的充电模块被集成到该加固结构中。
背景技术
这类副车架在机动车制造中用于固定车轮悬架在车身侧的铰接点。通常在前部车体的副车架上还额外固定着发动机、传动机构和/或转向机构。该副车架本身通常利用橡胶支承件弹性地连接在车身上。加固结构可以选择性地被设计为抗剪刚度的板或者优选十字形状的支柱组合体。通过抗剪刚度的板能够仅提高副车架的刚度，而支柱组合体额外还能够吸收力。
这种类型的文献DE 10 2012 023 363 A1描述了一种用于机动车的前部车体和后部车体的副车架，该副车架具有两个在车辆横向方向上彼此间隔开并通过至少一个横梁相互连接的纵梁，其中，该副车架具有用于提高扭转刚度的加固结构，用于无接触地传递能量的充电模块能够被集成到该加固结构中。该充电模块具有遮盖板和线圈单元，其中，在遮盖板和线圈单元之间布置有脱耦元件(内部脱耦装置)。
不利之处是，该脱耦元件在遮盖板和线圈单元之间必须布置得面积非常大，以便一方面确保线圈单元的有效脱耦，另一方面可靠地保持其重量。这对可制造性提出了相当高的要求。
发明内容
因此本发明的目的是提出一种用于机动车的副车架，其可更简单地制造。
该目的通过权利要求1的特征实现。
机动车的前部车体或后部车体的副车架具有两个纵梁，它们在车辆横向方向上彼此间隔开并通过至少一个横梁相互连接，其中，该副车架具有用于提高扭转刚度的加固结构，用于无接触地传递能量的充电模块被集成到该加固结构中，其中，所述充电模块与加固结构仅通过脱耦支承件相连。
通过将充电模块仅通过脱耦支承件与加固结构相连，充电模块可以较为容易地被安装并且通过脱耦支承件还能够有效地与加固结构的扭转脱耦。充电模块被理解为用于无接触地传递能量的系统的车身侧部件，如在公开文献DE 10 2010 042 395 A1和EP 0 253345 B1所示例性示出的那样。在此，电能(感应)通过优选静止布置的发送器传递到安装在车身侧的充电模块上以供进一步使用。为提高效率，充电模块和发送器需要彼此尽可能靠近地布置。因此，(板状的)充电模块在机动车上的深的定位是力争要实现的。加固结构可以选择性地被设计为抗剪刚度的板或者优选十字式安装的支柱组合体(所谓的十字支柱)。通过抗剪刚度的板可以仅提高副车架的刚度，而支柱组合体额外仍能够吸收力。副车架的纵梁优选镜像对称地布置并且能够直接或间接地——例如通过铸造接头——与至少一个横梁连接成敞开的或封闭的框架结构。
在一种优选的实施方案中，脱耦支承件被设计为橡胶-金属-套支承件。该稳定的金属外套负责在加固结构或充电模块中的可靠放置，而内套则通过弹性的中间层振动脱耦以用于接纳连接元件。
在一种优选的实施方案中，充电模块具有遮盖板和线圈单元，其中，所述线圈单元在装入位置中在测地学方面布置在遮盖板下方。为改善线圈单元的功能，需要针对周边的铁磁的结构件(例如纵梁、横梁和加固结构)加以屏蔽。为此，线圈单元被优选由铝制成的遮盖板部分包围并且其方式是使得遮盖板位于铁磁的结构件与线圈单元之间。线圈单元在运行期间至少部分被(对地静止的)发送器的交变磁场穿过，由此产生感应电压。合适的电力电子设备/功率电子设备将该电压加以转换并且传递至机动车的车载电网。
在一种优选的实施方式中，遮盖板通过脱耦支承件与加固结构连接。该遮盖板较为稳固并因此能够最佳地将充电模块本身保持在加固结构上。
在一种优选的实施方式中，脱耦支承件与加固结构接合在一起并且通过连接元件保持充电模块。连接元件可以例如是螺栓-螺纹-组合体。加固结构优选通过压配合保持脱耦支承件。
在一种优选的实施方式中，脱耦支承件被压入到加固结构的相应的接纳部中。接纳部特别优选被设计为以材料结合的方式固定到加固结构中的金属套，脱耦支承件被压入到该金属套中。
在一种优选的实施方式中，脱耦支承件与充电模块接合在一起并且通过连接元件保持在加固结构上。连接元件例如是螺栓-螺纹-组合体。充电模块优选通过压配合保持脱耦支承件。
在一种具有根据本发明的副车架的机动车中，充电模块与电能存储器连接。在一种优选的实施方式中，该能量存储器被设计为动力电池。如果机动车运动到对地静止的、行车道侧的发送器上方，则在副车架的加固结构中的充电模块的线圈单元接收到由发送器发出的交变磁场，并且产生感应电压。该电压由电力电子设备传递给动力电池，由此该动力电池被充电。为使机动车继续运动，以后可以从该动力电池中再次获取电压来驱动电机(E-Maschine)。
附图说明
本发明的其它细节和优点由下面借助附图对优选实施例的说明得出。
附图示出：
图1示出副车架的第一实施方式的侧面剖视图；
图2示出副车架的第一实施方式的另一侧面剖视图；
图3示出穿过副车架的第一实施方式的脱耦支承件的剖视图；
图4示出穿过副车架的第二实施方式的脱耦支承件的剖视图。
具体实施方式
根据图1和图2，用于机动车的前部车体的副车架1包括两个相对于车辆纵轴线镜像对称布置的、彼此间隔开的纵梁2(在此剖视图中仅示出其中之一)，这两个纵梁通过横梁3相互连接。在如此构成的副车架1上布置有当前被设计为十字支柱的加固结构4，用于提高扭转刚度。加固结构4在其中央具有自由面/裸露面。在该处安放充电模块5，该充电模块由遮盖板5a和线圈单元5b构成。遮盖板5a在安装状态下朝上覆盖线圈单元5b。优选由铝制成的遮盖板5a在其边缘上与脱耦支承件6通过螺纹连接，该脱耦支承件本身被固定保持在加固结构4中。在行驶运行中，脱耦支承件6使充电模块5与加固板4的变形脱耦。脱耦支承件6被设计为橡胶-金属-套支承件并且以形锁合的方式被压入到加固结构4的相应的套形状的接纳部中。插头7从线圈单元5b通至车辆侧的蓄能装置(未示出)。
图3示出根据图1和图2所示的第一实施方式的脱耦支承件6，其被设计为具有外套6a的橡胶-金属-套支承件，所述外套被压入到加固结构4的接纳部10中。利用环绕延伸的弹性体层6b使内套6c被弹性地保持在外套6a上，其中，内套6c还具有螺母9。螺母9具有内螺纹，其能够与被设计为螺栓的连接元件8的外螺纹共同作用。通过连接元件8保持充电模块5的遮盖板5a，其又保持线圈单元5b。
图4示出根据第二实施方式的脱耦支承件6，该脱耦支承件能够类似地应用于图1和图2的副车架中。该脱耦支承件6是橡胶-金属-套支承件，具有外套6a，该外套被压入到充电模块5的遮盖板5a的接纳部10中。利用环绕延伸的弹性体层6b使内套6c被弹性地保持在外套6a上。加固结构4承载具有内螺纹的螺母9。被设计为螺栓的连接元件8具有能够与螺母9的内螺纹共同作用的外螺纹。因而通过脱耦支承件6使遮盖板5a以弹性脱耦的方式固定在加固结构4上，其中，该遮盖板5a又保持线圈单元5b。
