具体实施方式
下面详细描述本发明的实施例,所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
下面参考附图详细描述根据本发明实施例的动力驱动***100,该动力驱动***100可以应用在车辆1000上,例如,混合动力车辆1000上。
根据本发明实施例的动力驱动***100可以包括:发动机1、多个输入轴、多个输出轴、第一电动发电机4、第二电动发电机6,当然,该动力驱动***100还可以包括其他机械部件,例如,第一离合装置5d、第二离合装置7等。
发动机1设置成可选择性地接合多个输入轴中的至少一个,也就是说,在发动机1输出动力时,发动机1能够与多个输入轴中的一个接合以传输动力,当然,发动机1还能够与多个输入轴中的多个同时接合以传输动力。每个输入轴上设置有挡位主动齿轮,每个输出轴上设置有挡位从动齿轮,挡位从动齿轮与挡位主动齿轮对应地啮合,通过挡位主动齿轮和挡位从动齿轮之间的啮合,可以实现输入轴和输出轴之间的动力传递,通过选取不同传动比的挡位主动齿轮和挡位从动齿轮,可以改变输出轴的输出转速。
发动机1与多个输入轴之间设置有第一离合装置5d,第一离合装置5d可以实现发动机1选择性地接合多个输入轴中的至少一个,如图1-图3所示,第一离合装置5d可以为双离合器,双离合器具有输入端51d、第一输出端52d和第二输出端53d,输入端51d可选择性地接合第一输出端52d和第二输出端53d的至少一个。也就是说,输入端51d可以接合第一输出端52d,或者,输入端51d可以接合第二输出端53d,或者输入端51d可以同时接合第一输出端52d和第二输出端53d。
例如,如图1-图3所示,多个输入轴包括:第一输入轴21和第二输入轴22,第一输出端52d与第一输入轴21相连,第二输出端53d与第二输入轴22相连。输出轴包括:第一输出轴31和第二输出轴32。
其中,挡位的布置数量和形式有多种,下面以两种为例进行详细说明。
第一种挡位布置形式:如图1-图6所示,第一输入轴21上设置有一挡主动齿轮1a、三挡主动齿轮3a和五挡主动齿轮5a,第二输入轴22上设置有二挡主动齿轮2a和四六挡主动齿轮46a。其中,第二输入轴22套设在第一输入轴21上,这样可以有效缩短动力驱动***100的轴向长度,从而可以降低动力驱动***100占用车辆1000的空间。
其中,按照与发动机1距离近远的方式,多个挡位主动齿轮的排布顺序为二挡主动齿轮2a、四六挡主动齿轮46a、三挡主动齿轮3a、一挡主动齿轮1a和五挡主动齿轮5a。通过合理布置多个挡位主动齿轮的位置,可以使得多个挡位从动齿轮和多个输出轴的位置布置合理,从而可以使得动力驱动***100结构简单,体积小。
第一输出轴31上空套设置有一挡从动齿轮1b、二挡从动齿轮2b、三挡从动齿轮3b和四挡从动齿轮4b,第二输出轴32上空套设置有五挡从动齿轮5b。其中一挡主动齿轮1a与一挡从动齿轮1b啮合,二挡主动齿轮2a与二挡从动齿轮2b啮合,三挡主动齿轮3a与三挡从动齿轮3b啮合,四六挡主动齿轮46a与四挡从动齿轮4b啮合,五挡主动齿轮5a与五挡从动齿轮5b啮合,四六挡主动齿轮46a与六挡从动齿轮6b啮合。
一挡从动齿轮1b与三挡从动齿轮3b之间设置有一三挡同步器13c,一三挡同步器13c可以用于同步一挡从动齿轮1b和第一输出轴31,以及可以用于同步三挡从动齿轮3b和第一输出轴31。
二挡从动齿轮2b与四挡从动齿轮4b之间设置有二四挡同步器24c,二四挡同步器24c可以用于同步二挡从动齿轮2b和第一输出轴31,以及可以同于同步四挡从动齿轮4b和第一输出轴31。
五挡从动齿轮5b的一侧设置有五挡同步器5c,五挡同步器5c可以用于同步五挡从动齿轮5b和第二输出轴32。
六挡从动齿轮6b的一侧设置有六挡同步器6c,六挡同步器6c可以用于同步六挡从动齿轮6b和第二输出轴32。
第二种挡位布置形式:如图7和图8所示,第一输入轴21上设置有一挡主动齿轮1a、三挡主动齿轮3a、五挡主动齿轮5a和七挡主动齿轮7a,第二输入轴22上设置有二挡主动齿轮2a和四六挡主动齿轮46a。其中,第二输入轴22套设在第一输入轴21上,这样可以有效缩短动力驱动***100的轴向长度,从而可以降低动力驱动***100占用车辆1000的空间。
其中,按照与发动机1距离近远的方式,多个挡位主动齿轮的排布顺序为二挡主动齿轮2a、四六挡主动齿轮46a、五挡主动齿轮5a、三挡主动齿轮3a、一挡主动齿轮1a和七挡主动齿轮7a。通过合理布置多个挡位主动齿轮的位置,可以使得多个挡位从动齿轮和多个输出轴的位置布置合理,从而可以使得动力驱动***100结构简单,体积小。
第一输出轴31上空套设置有二挡从动齿轮2b、三挡从动齿轮3b、六挡从动齿轮6b和七挡从动齿轮7b,第二输出轴32上空套设置有一挡从动齿轮1b、四挡从动齿轮4b和五挡从动齿轮5b。
其中一挡主动齿轮1a与一挡从动齿轮1b啮合,二挡主动齿轮2a与二挡从动齿轮2b啮合,三挡主动齿轮3a与三挡从动齿轮3b啮合,四六挡主动齿轮46a与四挡从动齿轮4b啮合,五挡主动齿轮5a与五挡从动齿轮5b啮合,四六挡主动齿轮46a与六挡从动齿轮6b啮合,七挡主动齿轮7a与七挡从动齿轮7b啮合。
二挡从动齿轮2b和六挡从动齿轮6b之间设置有二六挡同步器26c,二六挡同步器26c可以用于接合二挡从动齿轮2b和第一输出轴31,以及可以用于接合六挡从动齿轮6b和第一输出轴31。
三挡从动齿轮3b和七挡从动齿轮7b之间设置有三七挡同步器37c,三七挡同步器37c可以用于接合三挡从动齿轮3b和第一输出轴31,以及可以用于接合七挡从动齿轮7b和第一输出轴31。
一挡从动齿轮1b和五挡从动齿轮5b之间设置有一五挡同步器15c,一五挡同步器15c可以用于接合一挡从动齿轮1b和第二输出轴32,以及可以用于接合五挡从动齿轮5b和第二输出轴32。
四挡从动齿轮4b的一侧设置有四挡同步器4c。四挡同步器4c用于接合四挡从动齿轮4b和第二输出轴32。
多个输出轴与车辆1000的差速器联动。
需要说明的是,上述的“联动”可以理解为多个部件(例如,两个)关联运动,以两个部件联动为例,在其中一个部件运动时,另一个部件也随之运动。
例如,在本发明的一些实施例中,齿轮与轴联动可以理解为是在齿轮旋转时、与其联动的轴也将旋转,或者在该轴旋转时、与其联动的齿轮也将旋转。
又如,轴与轴联动可以理解为是在其中一根轴旋转时、与其联动的另一根轴也将旋转。
再如,齿轮与齿轮联动可以理解为是在其中一个齿轮旋转时、与其联动的另一个齿轮也将旋转。
在本发明下面有关“联动”的描述中,如果没有特殊说明,均作此理解。
第一电动发电机4设置成与车辆1000的差速器联动,联动方式有多种,此处结合附图详细描述。差速器处设置有主减速器从动齿轮8。
如图1-图3所示,第一电动发电机4通过齿轮传动组件与差速器的主减速器从动齿轮8联动,齿轮传动组件可以包括:传动齿轮一41、传动齿轮二42和传动齿轮三43,传动齿轮一41固定连接在第一电动发电机4的电机轴上,传动齿轮二42与传动齿轮一41啮合,传动齿轮二42和传动齿轮三43同轴固定,传动齿轮三43与差速器传动。这样第一电动发电机4和差速器之间传动路径短,传动效率高。
第一电动发电机4还可以与其中一个输出轴联动。
如图4所示,第一电动发电机4与第二输出轴32同轴相连,第一电动发电机4的动力可以通过第二输出轴32直接传递给差速器,这样第一电动发电机4和差速器之间传动路径短,传动效率高。
如图5所示,第一电动发电机4与第一输出轴31同轴相连,第一电动发电机4的动力可以通过第一输出轴31直接传递给差速器,这样第一电动发电机4和差速器之间传动路径短,传动效率高。
第二电动发电机6和发动机1位于第一离合装置5d的输入侧,第二电动发电机6可以位于第一离合装置5d与发动机1之间。通过将第二电动发电机6设置在第一离合装置5d的输入侧,可以有效减少动力驱动***100的轴向长度,而且可以使得第二电动发电机6的位置布置合理,可以提高动力驱动***100的结构紧凑性。
第二电动发电机6可以选取容量小体积小的电动发电机,这样可以满足变速器的小型化要求,由于变速器内部结构对空间有严格的要求,这样体积较小的第二电动发电机6占用变速器的体积较小,而且可以避免第二电动发电机6与其他部件例如第一离合装置5d之间发生干涉,从而可以使得变速器构造合理,结构紧凑。
多个输入轴位于第一离合装置5d的输出侧,第二电动发电机6设置成能够利用来自发动机1输出的至少部分动力在车辆1000驻车时进行驻车发电。也就是说,发动机1和第二电动发电机6可以分别与输入端51d相连,在车辆1000处于驻车状态时,发动机1的至少一部分动力可以直接传递给第二电动发电机6以使得第二电动发电机6发电,或者发动机1的一部分动力可以通过输入端51d间接传递给第二电动发电机6以使得第二电动发电机6发电。
下面结合附图描述发动机1和第二电动发电机6之间的连接布置关系。
如图1所示,输入端51d上可以设置有输入端外齿54d,第二电动发电机6与输入端外齿54d联动。这样发动机1的动力可以通过输入端51d和输入端外齿54d传递给第二电动发电机6,这样第二电动发电机6可以作为发电机使用以进行驻车发电。
如图2所示,第二电动发电机6与输入端51d可以同轴相连。第二电动发电机6可以设置在输入端51d和发动机1之间,这样发动机1的动力在向输入端51d传递时必然经过第二电动发电机6,此时第二电动发电机6可以作为发电机使用以进行驻车发电。
如图3所示,第二电动发电机6与发动机1之间可以设置有第二离合装置7。第二离合装置7可以为单离合器,单离合器可以控制发动机1和第二电动发电机6之间的接合断开,以及可以控制发动机1和输入端51d之间的接合断开。通过设置第二离合装置7,可以合理控制第二电动发电机6的驻车发电状态,从而可以使得动力驱动***100结构简单且驱动模式转换可靠。
优选地,第二离合装置7内置在第二电动发电机6的转子内部。这样可以更好地缩短动力驱动***100的轴向长度,从而可以减小动力驱动***100的体积,可以提高动力驱动***100在车辆1000上的布置灵活性。另外,当第二电动发电机6还可以作为启动机使用。
优选地,发动机1、第二离合装置7以及双离合器的输入端51d同轴布置。这样可以使得动力驱动***100结构紧凑,体积小。
需要说明的是,对于上述三个实施例的动力驱动***100,在轴向方向上,第二电动发电机6均位于发动机1和第一离合装置5d之间,这样可以有效减少动力驱动***100的轴向长度,而且可以使得第二电动发电机6的位置布置合理,可以提高动力驱动***100的结构紧凑性。
第一电动发电机4为动力驱动***100的主驱动电机,所以第一电动发电机4的容量和体积较大,第一电动发电机4可以与差速器传动,而且可以最大限度地缩小动力驱动***100的体积,而且可以避免第一电动发电机4和第二电动发电机6之间发生干涉现象。
其中,对于第一电动发电机4和第二电动发电机6来说,第一电动发电机4的额定功率大于第二电动发电机6的额定功率。这样第二电动发电机6可以选取体积小且额定功率小的电动发电机,从而可以使得动力驱动***100结构简单,体积小,而且在驻车发电时,第二电动发电机6和发动机1之间传动路径短,发电效率高,从而可以有效将发动机1的一部分动力转化成电能。其中第一电动发电机4的峰值功率同样大于第二电动发电机6的峰值功率。
优选地,第一电动发电机4的额定功率为第二电动发电机6的额定功率的两倍或两倍以上。第一电动发电机4的峰值功率为第二电动发电机6的峰值功率的两倍或两倍以上。例如,第一电动发电机4的额定功率可以为60kw,第二电动发电机6的额定功率可以为24kw,第一电动发电机4的峰值功率可以为120kw,第二电动发电机6的峰值功率可以为44kw。
其中,动力驱动***100布置倒挡传动路径的方式有多种,下面结合附图一一描述。
如图1-图5所示,动力驱动***100还可以包括:倒挡轴9,倒挡轴9上可以固定设置有倒挡轴第一齿轮91和倒挡轴第二齿轮92,其中,多个输出轴中的一个上空套设置有倒挡输出齿轮93,而且输出轴上还可以设置有用于接合倒挡输出齿轮的倒挡同步器。输出轴可以为第二输出轴32。
倒挡轴第一齿轮91与其中一个挡位主动齿轮啮合,倒挡轴第二齿轮92与倒挡输出齿轮93啮合。其中一个挡位主动齿轮可以是一挡主动齿轮1a,由此,传递到一挡主动齿轮1a处的动力可以依次经过倒挡轴第一齿轮91、倒挡轴9、倒挡轴第二齿轮92和倒挡输出齿轮93传递给第二输出轴32,第二输出轴32传递给差速器和车轮以驱动车辆1000反向运动,从而可以实现车辆1000的倒挡操作。
如图6和图7所示,多个输出轴中的一个上空套设置有倒挡输出齿轮93,而且输出轴上还可以设置有用于接合倒挡输出齿轮的倒挡同步器。输出轴可以为第二输出轴32。
倒挡输出齿轮93和其中一个挡位主动齿轮通过第一中间惰轮94联动。第一中间惰轮94可以保证倒挡输出齿轮93和其中一个挡位主动齿轮的同向转动,进而可以实现车辆1000的倒挡操作。第一中间惰轮94可以为单齿轮,该齿轮直接啮合在其中一个挡位主动齿轮和倒挡输出齿轮93之间。具体地,其中一个挡位主动齿轮可以为二挡主动齿轮2a。
如图8所示,多个输出轴中的一个上空套设置有倒挡输出齿轮93,而且输出轴上还可以设置有用于接合倒挡输出齿轮的倒挡同步器。输出轴可以为第二输出轴32。
倒挡输出齿轮93和其中一个挡位从动齿轮啮合。由此,倒挡输出齿轮93可以与该挡位从动齿轮对应的挡位主动齿轮同向转动,进而可以实现车辆1000的倒挡操作。挡位从动齿轮可以为二挡从动齿轮2b。
优选地,在上述多个实施例中,倒挡输出齿轮93和相邻的一个挡位从动齿轮共用倒挡同步器,这样可以减少布置在第二输出轴32上的同步器的数量,从而可以有效简化动力驱动***100的结构。
在图1-图6所示的动力驱动***100中,上述的挡位从动齿轮可以为六挡从动齿轮6b,也就是说倒挡同步器即六挡同步器6c。在图7和图8所示的动力驱动***100中,上述的挡位从动齿轮可以为四挡从动齿轮4b,也就是说倒挡同步器即四挡同步器4c。
下面结合附图详细描述根据本发明实施例的用于车辆1000的动力驱动***100的工况模式。其中,图2和图3中所示的动力驱动***100与图1所示的动力驱动***100的区别主要体现在第二电动发电机6的布置方式,但是第二电动发电机6的布置方式对工况模式影响较小,图4和图5所示的动力驱动***100余图1所示的动力驱动***100的区别主要体现在第一电动发电机4的布置方式,图6-图8所示的动力驱动***100与图1所示的动力驱动***100的区别主要体现在倒挡的布置形式,所以图2-图8中所示的动力驱动***100的工况模式与图1所示的动力驱动***100的工况模式基本相同,下面以图1所示的动力驱动***100的工况模式为例进行详细说明。
纯发动机模式:发动机1的动力经过第一离合装置5d传递给第一输入轴21和/或第二输入轴22,然后通过对应的挡位齿轮副传递给第一输出轴31或第二输出轴32,最终动力传递给差速器以驱动车轮转动。其中挡位齿轮副为对应的挡位主动齿轮和挡位从动齿轮。其中,第一离合装置5d的输入端51d选择性地接合两个输出端中的至少一个。
纯电动模式:第一电动发电机4作为电动机使用,第一电动发电机4的动力传递给差速器以驱动车轮转动。其中第一电机动力轴41同步器处于接合状态。
混合动力模式:即上述纯发动机模式和纯电动模式之间的结合,发动机1的动力和第一电动发电机4的动力在主减速器从动齿轮8处耦合。
驻车发电模式:发动机1的动力全部通过第一离合装置5d的输入端51d传递给第二电动发电机6,第二电动发电机6作为发电机使用以进行驻车发电。
行车发电模式一:发动机1的一部分动力通过第一离合装置5d、输入轴、输出轴传递给差速器以驱动车轮转动,发动机1的另一部分动力通过可以用于供第二电动发电机6发电。
行车发电模式二:发动机1的动力通过第一离合装置5d、输入轴、输出轴传递给差速器以驱动车轮转动,一部分动力可以传递给第一电动发电机4以供第一电动发电机4发电。
