Description

一种混联单档汽车动力系统
技术领域
本申请涉及汽车动力领域，具体涉及一种混联单档汽车动力系统。
背景技术
当前普遍使用的燃油发动机汽车存在种种弊病，随着世界各国对改善环保的呼声日益高涨，各种各样的电动汽车脱颖而出。虽然人们普遍认为未来是电动汽车的天下，但是电池技术问题阻碍了电动汽车的应用。由于电池的能量密度与汽油相比差上百倍，远未达到人们所要求的数值，电动汽车还无法取代燃油发动机汽车，于是混合动力装置的汽车应运而生。这种混合动力装置既发挥了发动机持续工作时间长的优点，又有利于减少污染排放。
由于汽车动力系统由单动力变为混合动力，因此汽车的变速器结构也发生改变。目前，为了实现混合动力，汽车动力系统为发动机和电动机两级传动设置，但这种设置无法保证汽车足够的动力，或者为两级和三级传动复合设置，并配以一个或多个传统离合器，但是在换挡时存在整车动力系统衰减较大，有明显顿挫感等问题。
发明内容
鉴于上述问题，本申请提出了一种混联单档汽车动力系统，以便解决或者至少部分解决上述存在的问题。
为了达到上述目的，本发明的技术方案是这样实现的：
本发明提供一种混联单档汽车动力系统，所述动力系统包括发动机、ISG 电机、发动机传动机构、电磁离合器、驱动电机、驱动电机传动机构和动力输出轴；其中，所述ISG电机和所述驱动电机设置在不同轴上；所述ISG电机设置在所述发动机传动机构的传动轴上，所述电磁离合器设置在所述发动机传动机构的所述传动轴上或所述动力输出轴上，且所述发动机传动机构的末端齿轮设置在所述动力输出轴的一端；所述驱动电机减速机构的末端齿轮设置在所述动力输出轴的另一端。
进一步的，所述发动机传动机构包括发动机输出轴和第一输出轴，所述发动机的输出轴上设置有所述ISG电机、所述电磁离合器和第一齿轮，所述第一齿轮靠近所述电磁离合器的一侧设置有结合齿，且空套在所述发动机输出轴上；所述第一输出轴与所述动力输出轴为同一轴，所述第一输出轴上设置有第二齿轮。
进一步的，所述发动机传动机构包括发动机输出轴和第一输出轴，所述发动机输出轴上设置有所述ISG电机和第一齿轮，所述第一输出轴与所述动力输出轴同轴间隔设置，且所述第一输出轴上设置有第二齿轮，所述第二齿轮靠近所述电磁离合器的一侧设置有结合齿，且所述电磁离合器设置在所述动力输出轴上。
进一步的，所述电磁离合器包括电磁离合器内套和电磁离合器线圈，所述电磁离合器线圈设置在所述电磁离合器内套中，所述电磁离合器内套的端面上设置有结合齿。

采用上述混联单档汽车动力系统具有以下优点：
本发明通过对TM电机、ISG电机以及电磁离合器的位置设置，可以实现至少五种工作模式；通过ISG电机和TM电机异轴设置，TM电机三级减速，为车辆提供足够的动力；发动机两级传动输出，使车辆在高速行驶时发动机处于高效工作区；ISG电机与发动机直连，有效减少传递损失，发电效率高；本动力系统设置使汽车在换挡时，整车动力衰减较少，无顿挫感；并且本动力系统结构简单，制造陈本低。

本发明提供一种混联单档汽车动力系统，该动力系统包括发动机1、ISG 电机3、发动机传动机构、电磁离合器、驱动电机5、驱动电机传动机构和动力输出轴；其中，ISG电机3和驱动电机5设置在不同轴上；ISG电机3设置在发动机传动机构的传动轴上，ISG电机3与发动机1直接连接，提高了 ISG电机3的发电效率，ISG电机3可用于启动发动机1或为汽车电池充电，电磁离合器设置在发动机传动机构的传动轴上或动力输出轴上，电磁离合器的状态分为在档或者不在档，通过电磁离合器的状态改变来控制发动机1是否处于驱动汽车状态，当电磁离合器在档时，发动机1为车辆提供驱动动力，当电磁离合器不在档时，发动机1不为车辆提供驱动动力，且发动机传动机构的末端齿轮设置在动力输出轴的一端；驱动电机减速机构的末端齿轮设置在动力输出轴的另一端。本发明中的动力系统包括发动机1和驱动电机5两个动力装置，两个动力装置独立工作，分别通过发动机传动机构和驱动电机传动机构来实现对车辆的驱动。
参见下表1，该动力系统可以提供五种驱动模式，即纯电模式、串联模式、并联模式、发动机直驱模式和制动回收模式。当驱动模式为纯电模式时，发动机1和ISG电机3不工作，电磁离合器处于不在档状态，驱动电机5工作，只用驱动电机5提供动力驱动车辆。当驱动模式为串联模式时，ISG电机3工作，同时ISG电机3启动发动机1，使发动机1工作，电磁离合器处于不在档状态，驱动电机5工作，此时，发动机1驱动ISG电机3发电供给汽车电池，驱动电机5为车辆提供动力。当驱动模式为并联时，发动机1工作，ISG电机3工作或不工作，电磁离合器处于在档状态，驱动电机5工作，此时，发动机1和驱动电机5一起提供动力驱动车辆，ISG电机3处于发电或不发电状态。当驱动模式为发动机直驱时，发动机1工作，ISG电机3不工作，电磁离合器处于在档状态，驱动电机5不工作，此时，发动机1提供动力驱动车辆，驱动电机5处于空转状态。当驱动模式为制动回收时，发动机1和ISG电机3不工作，电磁力合器处于不在档状态，驱动电机5工作，此时，驱动电机5反拖制动车辆，对车辆进行制动，驱动电机5把车辆的动能转换成电能，储存回汽车电池。

表1
在一个实施例中，发动机传动机构包括发动机输出轴和第一输出轴，发动机的输出轴上设置有ISG电机3、电磁离合器和第一齿轮4，第一齿轮4 靠近电磁离合器的一侧设置有结合齿，且空套在发动机输出轴上，第一齿轮 4侧边的结合齿可与电磁离合器内套12端面上的结合齿啮合；第一输出轴与动力输出轴为同一轴，第一输出轴上设置有第二齿轮6。发动机1驱动发动机输出轴转动时，电磁离合器内套12跟随转动，由于第一齿轮4空套在发动机输出轴上，当电磁离合器不在档时，第一齿轮4不会随着发动机输出轴的转动而转动，当电磁离合器在档时，第一齿轮4侧边的结合齿就会与电磁离合器内套12端面上的结合齿啮合，进而电磁离合器内套12带动第一齿轮4 转动，然后发动机输出轴通过第一齿轮4和第二齿轮6啮合驱动第一输出轴转动。
在一个实施例中，发动机传动机构包括发动机输出轴和第一输出轴，发动机输出轴上设置有ISG电机3和第一齿轮4，第一输出轴与动力输出轴同轴间隔设置，且第一输出轴上设置有第二齿轮6，第二齿轮6靠近电磁离合器的一侧设置有结合齿，且电磁离合器设置在动力输出轴上，第二齿轮6上的结合齿可与电磁离合器内套12上的结合齿啮合。发动机1工作时，驱动发动机输出轴转动，发动机输出轴通过第一齿轮4和第二齿轮6啮合驱动第一输出轴转动，第一输出轴与动力输出轴间隔设置，动力输出轴不会直接随着第一输出轴转动而转动，只有电磁离合器在档时，第二齿轮6上的结合齿与电磁离合器内套12上的结合齿啮合，第一输出轴实现驱动动力输出轴转动。
在一个优选实施例中，电磁离合器包括电磁离合器内套12和电磁离合器线圈11，电磁离合器线圈11设置在电磁离合器内套12中，电磁离合器线圈 11与电磁离合器内套12四周都有足够的空间，使电磁离合器线圈11与电磁离合器内套12相对移动，电磁离合器线圈14相对于发动机传动机构的传动轴或动力输出轴固定不动，电磁离合器内套12的端面上设置有结合齿。
在一个实施例中，驱动电机传动机构包括驱动电机输出轴、中间轴和第二输出轴；且第二输出轴和动力输出轴为同一轴；驱动电机输出轴上设置有第七齿轮15，中间轴上设置有第八齿14轮和第五齿轮13，第二输出轴上设有第六齿轮10。驱动电机5工作时，驱动驱动电机输出轴转动，驱动电机输出轴通过第七齿轮15与第八齿轮14啮合驱动中间轴转动，中间轴通过第五齿轮13与第六齿轮10啮合驱动第二输出轴转动。驱动电机传动机构为三级减速，此结构可为车辆提供足够大的扭力，保证车辆的强劲动力。
在一个实施例中，发动机输出轴和驱动电机输出轴分别设置在动力输出轴的两侧，且中间轴和发动机输出轴同轴且间隔设置。
在一个实施例中，ISG电机3固定在发动机输出轴上且同轴设置，有利于提高ISG电机3的发电效率。
在一个实施例中，ISG电机3的输出轴与发动机的输出轴通过减振器2 连接，该减振器2为扭转减振器，可以降低发动机曲轴与传动系接合部分的扭转刚度，从而降低传动系扭振固有频率，增加传动系扭转阻尼，抑制扭转共振相应的振幅，并衰减因冲击产生的瞬态扭振，消除变速器怠速噪声和主减速器、变速器的扭振及噪声，改善离合器的接合平顺性。
进一步的，驱动电机5为TM电机，TM电机为大扭矩电机，可以为车辆提供足够动力。
进一步的，动力输出轴中间部位设置有第三齿轮7，第三齿轮7通过第四齿轮8驱动差速器9旋转。
综上所述，本发明公开的一种混联单档汽车动力系统，包括发动机、ISG 电机、发动机传动机构、电磁离合器、驱动电机、驱动电机传动机构和动力输出轴；其中，所述ISG电机和所述驱动电机设置在不同轴上；所述ISG电机设置在所述发动机传动机构的传动轴上，所述电磁离合器设置在所述发动机传动机构的所述传动轴上或所述动力输出轴上，且所述发动机传动机构的末端齿轮设置在所述动力输出轴的一端；所述驱动电机减速机构的末端齿轮设置在所述动力输出轴的另一端。本发明通过对TM电机、ISG电机以及电磁离合器的位置设置，可以实现至少五种工作模式；通过TM电机三级传动和发动机两级传动，提高了汽车的动力输出；并且该动力系统具有结构简单，制造成本低等优点。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化、替换或改进，都应涵盖在本发明的保护范围之内。
在此处所提供的说明书中，说明了大量具体细节。然而，能够理解，本申请的实施例可以在没有这些具体细节的情况下实践。在一些实例中，并未详细示出公知的方法、结构和技术，以便不模糊对本说明书的理解。
