Description
相关申请的交叉参考
本申请对2001年12月7日提交的美国临时专利申请60/337,994的权益提出要求,其全部内容在此引入作为参考。
技术领域
本发明涉及一种适于电力牵引的轻型车辆上所用的车轮马达牵引组件,该车轮马达牵引组件被封装以便配装在轻型车辆的车轮空腔中,并且具有用于车辆底盘部件的安装结构,其集成了车辆的制动、悬架和转向功能。
背景技术
车轮马达在车辆上的应用保证了精确控制单独输入和输出每个车轮的电力,这可以产生增大的牵引控制、改进的可驱动性、操纵性和制动性。可能需要将车轮马达用于适于电力牵引的车辆中,例如带有电池电源、燃料电池、或者燃料电池、电池电源或内燃机的混合式结构的车辆。通过使用车轮马达实现的轮胎滑动损失的降低可以产生改进的燃油经济性。因为可以想到不再需要带有齿轮减速装置、驱动轴、马达安装件和差速器的车载马达,所以使用车轮马达可以产生改进的车辆封装。将车轮马达设计有足够的连续和峰值功率以便驱动轻型车辆,同时将尺寸、重量和总的非悬挂质量(即,从车辆悬架系统轴向向外或者位于轮胎和车轮一侧上的质量)减到最小,这些方案已被证明是目前的挑战。标准轻型车轮的空间限制、承受车辆底盘载荷的必要强度以及与车辆底盘部件的可充分连接性是进一步的设计考虑因素。
发明内容
用于轻型车辆底盘上的车轮马达牵引组件包括车轮和电动马达,该电动马达可操作地连接在车轮空腔中以便驱动地转动车轮并且具有不可转动的马达外壳。该马达外壳构制成基本上封住向内开口的车轮空腔的内端。不可转动的马达外壳还包括电连接器和结构连接器,该电连接器和结构连接器都适于将车轮马达牵引组件连接到底盘上。可操作地连接到马达外壳上的悬架系统结构连接器和转向系统结构连接器构制成将车轮马达牵引组件分别连接到车辆底盘上的悬架系统和车辆底盘上的转向系统上。当马达外壳通过悬架系统结构连接器和转向系统结构连接器将车轮与底盘结构互连时,该马达外壳构制成承受车辆底盘的载荷。
车轮马达牵引组件包括可转动的车轮,该车轮具有径向外侧轮胎支承部分和径向内侧轮毂支承部分,这两个部分配合构制成限定了车轮空腔。该车轮空腔相对于车辆底盘轴向向内开口并且具有车轮内周边和车轮外周边。车轮可拆卸地连接到轮毂上以便使得车轮可与轮毂一起转动。车轮马达牵引组件还包括转子,该转子在车轮内周边和车轮外周边之间位于车轮空腔中。转子可操作地连接到轮毂支承部分上以便驱动地转动车轮。不可转动的定子在车轮内周边和车轮外周边之间位于车轮空腔中以便驱动地转动转子。转子和定子一起组成马达。
可转动的制动盘可操作地连接到车轮和转子上,并且位于车轮空腔中的制动卡钳可松脱地连接到马达外壳上,制动卡钳适于选择性地将力施加在制动盘上。该制动盘机械连接到轮毂上。在一个实施例中,制动卡钳与底盘上的液压制动管线可操作地连接和响应,并且构制成响应于该液压管线上的液压力将力施加在制动盘上。本发明包括马达,其包括转子和定子。在一个实施例中,马达构制成进行再生制动。本发明的一个实施例还包括位于车轮空腔中的机械驻车制动卡钳,该机械驻车制动卡钳可松脱地连接到马达外壳且可操作地连接到底盘上的驻车制动缆索上。

制动控制单元108分析制动控制单元输入信号110和传感器信号118,并且根据预编程的算法选择性地向马达21发送马达控制信号120,或者向制动致动器114发送制动致动器控制信号122,或者进行这两种操作。马达21可操作地连接到能量存储装置124上。马达控制信号120闭合了马达21和能量存储装置124之间的回路126,使马达将其一些电能形式的能含量转向能量存储装置124。电能这样排向能量存储装置124就使得马达21变慢,同时在能量存储装置124中收集电能以便以后使用。制动控制单元108也可以将制动致动器控制信号122发送到制动致动器114,使得制动致动器114向车轮4施加机械力128。本发明还包括再生制动系统的其他构型。

因此,参见图1,车轮4具有可操作地连接在车轮4中的电动马达21,用于驱动地转动车轮4。电动马达21具有马达外壳19。转向系统结构连接器28可操作地连接到马达外壳19上,以便将车轮马达牵引组件2连接到底盘3上的转向系统上。如图8a中所示,上悬架系统结构连接器26和下悬架系统结构连接器27可操作地连接到马达外壳19上,以便将车轮马达牵引组件2连接到底盘3上的转向系统上。马达外壳19构制成这样,当其通过悬架系统结构连接器26、27和转向系统结构连接器28将车轮4与底盘3结构互连时承受车辆载荷。换句话说,马达外壳19是充分结构化的以便至少部分地支承车辆底盘3。
尽管详细描述了用于实现本发明的最佳模式,但是本发明相关领域的普通技术人员将会认识到用于在所附权利要求书的范围内实现本发明的各种替代设计和实施例。
