动力系组及其控制方法

本专利申请要求于2019年7月30日提交的第102019000013350号意大利专利申请的优先权，其全部公开内容通过引用并入本文。
技术领域
本发明涉及一种用于机动车辆的动力系组的附件传动装置以及包括这样的传动装置的动力系组。本发明优选但不排他地在混合动力系组中实施，下面将参考混合动力系组而不会因此丧失一般性。
背景技术
众所周知，具有混合动力驱动的车辆包括内燃发动机和至少一个电机，根据车辆的运行条件，电机可以用作发电机或用作与内燃发动机一起(或作为内燃发动机的替代)来提供马达扭矩的马达内燃发动机内燃发动机。
使用连接在车辆的内燃发动机与传动装置之间的电机的配置通常称为“P2”。已知适于放置在车辆的内燃发动机与传动装置之间的模块化单元(并且因此通常称为“P2模块”)，除了电机之外，该模块化单元还包括一个或两个离合器，用于选择性地将内燃发动机和/或电机以及相应的致动器和传动装置元件连接到传动装置。
用于机动车辆的动力系组也是已知的，其设有布置在内燃发动机的与传动装置相对的一端(通常由“前端”或“P0”表示)上的附件传动装置。附件传动装置(通常是皮带传动装置)将一个或多个附件连接到曲轴。这样的附件典型地包括用作交流发电机和/或马达的电机以及用于空调系统的压缩机，而附件传动装置包括连接到曲轴和每个附件的相应的皮带轮、与前述皮带轮配合的皮带以及适于确保皮带的最小张力的张紧器。
在电机被专门用作交流发电机(发电机)的情况下，已知在交流发电机与相应的皮带轮之间放置单向离合器或飞轮，目的是当皮带轮由马达驱动时将扭矩从皮带轮传递到电机，同时允许电机在可能发生这种情况(例如在曲轴突然减速的情况下)的过渡操作条件下比皮带轮转速快。这样，就避免了电机的高惯性使皮带承受不希望的张力峰值。
然而，在频率增加的情况下，其中电机也被用作马达，使用如上所述的飞轮是不可能的，因为电机必须能够根据操作条件接收扭矩或将扭矩传递到相应的皮带轮。
在这种情况下，为了确保皮带在所有操作条件下的最小张力，使用了双张紧器，该双张紧器具有作用在电机上游的皮带的跨度上的第一张紧皮带轮和作用在电机下游的皮带的跨度上的第二张紧皮带轮，因为根据操作条件，两个跨度都可以是松跨度。
上述已知的解决方案可以彼此结合，以形成混合动力系组，其具有处于位置P0的电机(下文中：P0电机)和处于位置P2的电机(下文中：P2电机)；这两台机器可以采用不同的控制策略(例如，一台机器仅作为马达，另一台机器以可逆方式运行)。
此外，内燃发动机的启动可以通过P0电机、P2电机或者甚至通过与发动机飞轮链接的第三电机(传统的起动马达)来实现。
例如，在P0电机仅用作马达并且内燃发动机的启动通过P2电机或起动马达实现的情况下，附件传动装置的皮带张力可能达到不可接受的最小值，如图4所示，这可能导致噪音和皮带过早损坏。
发明内容
本发明的目的是实现解决上述问题的附件传动装置。
前述目的通过根据权利要求1所述的附件传动装置来实现。
本发明还涉及根据权利要求4所述的动力系组。

为了更好地理解本发明，参考附图描述了非限制性的、优选的说明性实施例，其中：
图1是包括根据本发明的附件传动装置的混合动力系组的示意性平面图；
图2是根据本发明的附件传动装置的示意性前视图；
图3是沿着图2所示的线III-III的示意性横截面图；
图4是示出常规类型的附件传动装置中皮带张力变化的曲线图；和
图5是示出根据本发明的附件传动装置中皮带张力变化的曲线图。
具体实施方式
参考图1，用于机动车辆的动力系组整体上由1表示。
动力系组1包括带有曲轴3和混合模块4的内燃发动机2(以下简称为“内燃机2”)。
混合模块4在使用中定位在车辆的内燃机2与传动装置T之间，并且连接到曲轴3的面向传动装置T的端部5
混合模块4包括电机6和解除联接离合器7，解除联接离合器7适于选择性地将电机6连接到曲轴3和传动装置T。
离合器7包括至少一个离合器片8和片10，离合器片8与连接到曲轴3的端部5的飞轮9轴向固定并旋转结合，片10能轴向位移并与模块4的中间轴11旋转结合。离合器7最后包括液压致动器12，其作用在片10上以控制离合器。
中间轴11通过已知类型的扭转振动阻尼器(未示出)连接到皮带轮14，该扭转振动阻尼器容纳在所述皮带轮内。
皮带轮14通过皮带15连接到皮带轮16，皮带轮16连接到电机6。
固定到皮带轮14的是柔性板17或“挠性板”，其构成适于连接到变矩器18的模块4的输出元件，变矩器18构成传动装置T的输入元件。
动力系组1最后包括连接到曲轴的与端部5相对的端部20的附件传动装置19。
附件传动装置19(图2)包括固定到曲轴3的端部20的第一皮带轮21、链接到第二电机23的第二皮带轮22和用于驱动空调系统的压缩机25的第三皮带轮24。三个皮带轮21、22和24通过皮带26相互连接。常规类型的张紧器28作用于在第二皮带轮22与第三皮带轮24之间延伸的皮带26的跨度26a上。皮带轮21、22和24沿图3中箭头所示的相同旋转方向R旋转，并且与曲轴3的旋转方向一致。
根据本发明，单向离合器29(图3)定位在第二电机23的轴33与第二皮带轮22之间，该单向离合器适于将扭矩从电机23传递到第二皮带轮22，但不能将扭矩从第二皮带轮22传递到电机23。换句话说，单向离合器29允许电机23沿传动装置19的旋转方向R驱动第二皮带轮22，但是当第二皮带轮22倾向于在旋转方向R上比电机23转速快时，解除第二皮带轮22与电机23的联接。
动力系组1最后包括用作起动马达的第三电机30，该第三电机30设置有与飞轮的齿接部啮合的输出小齿轮31。有利地，第三电机30是能够执行内燃机2的快速启动的无刷电机。
动力系组1的功能如下。
当接合了离合器7后，中间轴11连接到车辆的内燃机2以及电机6和传动装置T。
在这种状态下，电机6既可以用作发电机(用于在燃烧动力驱动期间对电池进行再充电或者用作再生制动器)，也可以用作电机以与电机23一起提供附加扭矩(增压)。
当离合器7脱离接合时，电机6可以用于电驱动、电制动系统以及用于内燃机关闭时的“滑行”。
内燃机2的启动(冷启动以及从电驱动状态的启动)通过第三电机30来执行。在这个阶段，离合器7脱离接合。
在启动阶段，在附件传动装置19中，皮带26由链接到曲轴3的皮带轮21引导，并将运动传递到皮带轮22、24。当皮带轮22趋向于比电机23转速快时，单向离合器29使电机23与皮带轮22脱离联接。
为了更好地理解根据本发明的单向离合器29的效果，图4和图5示出了在没有单向离合器29的常规附件传动装置(图4)和设置有根据本发明的单向离合器29的附件传动装置中皮带26的张力的进展。特别地，张力分别在布置在皮带轮22与24之间、皮带轮24与21之间以及皮带轮22与21之间的三个区段26a、26b和26c中测量，并随时间变化示出在曲线图中。在0与2之间的时间间隔内，可以观察到发动机关闭(由电机6驱动)时张力的进展；可以观察到内燃机2通过电马达30的启动阶段中的张力过程为2s。
从图4中可以明显看出，在驱动发动机时皮带张力的平均值约为250牛顿的背景下，在启动时，在区段26c中出现幅度很大的张力振荡，约为大概300牛顿，最小峰值约为20牛顿。主要由于在启动时在由燃烧引起的扭转振动存在的情况下电机23的惯性导致的如此低的值会导致打滑以及噪音。
图5示出了在根据本发明的单向离合器29存在的情况下相同张力的进展，通过该进展，电机23在内燃机2启动时与附件传动装置19脱离联接，在该状态下，电机23倾向于由皮带26驱动。传动装置的动态性能的有效改善是显而易见的，其中皮带26的区段26c中张力振荡的幅度降低到大约40牛顿，并且其中最小峰值约为225牛顿(仍然与当驱动内燃机时约为大约250牛顿的皮带张力平均值相比)。
最后，很明显，所描述的传动装置19和动力系组1可以通过不超出权利要求限定的保护范围的修改和变型来补充。
