 有益效果
综上所述，轴带设备的驱动力来自于发动机尾气的余热余压，因此轴带设备不再消耗发动机的主轴动力，因此可以提高发动机的净输出功率，从而提高了发动机的效率。而且，轴带设备模组的模块化设计能够使动力系统的结构更加简洁。
附图说明
图1是动力系统的一个实施例的系统简化示意图。
图2是轴带设备模组的一个实施例的简化示意图。
 本发明的实施方式
在详细描述实施例之前，应该理解的是，本发明不限于本申请中下文或附图中所描述的详细结构或元件排布。本发明可为其它方式实现的实施例。而且，应当理解，本文所使用的措辞及术语仅仅用作描述用途，不应作限定性解释。本文所使用的“包括”、“包含”、“具有”等类似措辞意为包含其后所列出之事项、其等同物及其它附加事项。特别是，当描述“一个某元件”时，本发明并不限定该元件的数量为一个，也可以包括多个。
图1是动力系统的一个实施例的系统简化示意图。如图1，该动力系统包括发动机10、透平12、转轴14、至少一个轴带设备16和至少一个连接结构18。图1例示了具有三个轴带设备16和三个连接结构18的例子，但在其它实施例中，轴带设备和连接结构的数量可以是一个或多个。
发动机10用以提供动力系统的主动力。发动机10例如为活塞式柴油发动机。
透平12与发动机10的排气口连通用以接收发动机10的尾气，这样利用发动机10的尾气驱动透平旋转。在发动机10未装备增压器的情况下，透平12接收的尾气可以是从发动机10的排气门直接获取；在发动机10装备有增压器的情况下，透平12接收的尾气可以是从增压器的排气口获取。
转轴14与透平12连接以被透平12驱动旋转。轴带设备16通过连接结构18与转轴14连接。轴带设备16例如为一个动力系统中的辅助设备。当动力系统为车辆的动力系统时，轴带设备16可以是发电机、水泵、油泵、空调压缩机、制动空气压缩机或助力泵等。
每个连接结构18连接在转轴14与其中一个轴带设备16之间。这些轴带设备16一般是根据需要才运行，因此这些连接结构18要能够独立地在接合状态和分离状态之间切换，使得在接合状态，旋转的转轴14的动能通过一个连接结构18传递至一个对应的轴带设备16以驱动对应的轴带设备16，而在分离状态，转轴14与对应的轴带设备16分离，因此停止驱动对应的轴带设备16。能够实现上述功能的连接结构18的一个具体例子是电磁离合器。
动力系统还包括控制器20，用于控制这些连接结构18的结合和分离状态。控制器20可以根据用户的选择而进行控制，也可以根据动力系统的运行自动控制这些连接结构18的结合和分离状态。
在图1的实施例中，这些轴带设备16的驱动力来自于发动机尾气的余热余压。具体而言，这些轴带设备16的驱动装置包括用以接收发动机10的尾气以被尾气驱动旋转的透平12、与透平12连接以被透平12驱动旋转的转轴14，以及将转轴14的动能传递至轴带设备16的连接结构18。如此，利用上述驱动装置驱动的轴带设备16不再消耗发动机10的主轴动力，因此可以提高发动机10的净输出功率，从而提高了发动机10的效率。
图2是轴带设备模组的一个实施例的简化示意图。如图2，轴带设备模组包括透平22、转轴24、轴带设备26、连接结构28以及模组机壳30。其中，透平22、转轴24、多个轴带设备26、多个连接结构28的构造可以与图1的实施例中的相同。连接结构28沿着转轴24的轴向布置。至少转轴24、轴带设备26和连接结构28固定在模组机壳30内，这样轴带设备模组可以构成一个整体，以便于整个地安装在动力系统（例如图1所示的动力系统）中或从动力系统中拆除。在其它实施例中，透平22也可以固定在模组机壳30中。这种模块化的设计能够使动力系统的结构更加简洁。
综上所述，本文提供了一种轴带设备驱动装置、轴带设备模组及动力系统。轴带设备的驱动力来自于发动机尾气的余热余压，因此轴带设备不再消耗发动机的主轴动力，因此可以提高发动机的净输出功率，从而提高了发动机的效率。而且，轴带设备模组的模块化设计能够使动力系统的结构更加简洁。
本文所描述的概念在不偏离其精神和特性的情况下可以实施成其它形式。所公开的具体实施例应被视为例示性而不是限制性的。因此，本发明的范围是由所附的权利要求，而不是根据之前的这些描述进行确定。在权利要求的字面意义及等同范围内的任何改变都应属于这些权利要求的范围。
