Description

一种混合动力车辆传动系统及汽车
技术领域
本发明属于车辆传动系统领域，具体涉及一种混合动力车辆传动系统及汽车。
背景技术
随着世界各国环境保护的措施越来越严格，新能源汽车的市场份额与日俱增。受制于纯电动汽车无法满足连续长距离续航的原因，混合动力车辆由于其节能、低排放、动力强等特点成为整个汽车行业研究与开发的一个重点。然而，由于混合动力驱动车辆具有两套动力系统，以及两套动力系统的管理控制系统，其结构十分复杂。
目前市面上很多混合动力车辆采用了公开号为CN103298637B的专利文献中公开的一款混合动力车辆的驱动装置。如图1所示，本驱动装置可实现三条动力传递路径：T1、高速行驶时结合离合器80，发动机50通过离合器80、齿轮对30和40，直接驱动车轮47；T2、一方面，发动机50通过齿轮对10拖动发电电动机60发电，齿轮对10增加电机速度，以提高发电效率；另一方面，起动时，利用发电电动机60的驱动力起动发动机50；T3、牵引电动机70经齿轮对20和40减速增扭，驱动车轮47；该驱动装置传动效率高、动力性好，上市后受到市场欢迎。然而，从整体结构上而言，该驱动装置的发动机50、发电电动机60以及牵引电动机70采用偏轴布置，径向体积大，制造难度大，难以控制NVH性能；此外，在高速恒速的工况下，发动机50无需太大扭矩，而牵引电动机70无法断开动力传输，只能介入驱动或反拖充电，造成动能过剩或转化能源损失。

本发明实施例中，所述第一行星太阳轮301、所述第一离合器602的主动端和所述第二离合器603的主动端同轴；所述第二离合器603的被动端固定连接到所述第一电动机2的第一转子201上，所述第一转子201与发动机1同轴，二者之间同轴设置有减振装置7；所述第一转子201的外侧同轴设置有第一定子202，所述第一定子202固定在变速器壳体8上；所述第一行星架302与所述输出总成11的输出齿轮1101同轴，所述第一行星架302的一端通过第一连接部1201与所述第二行星内齿圈403固定连接，所述第一行星架302的另一端通过第二连接部1202与所述第一离合器602的被动端固定连接；所述第一行星内齿圈303通过第三连接部1203与所述第二行星架402固定连接；所述第一行星内齿圈303和所述第二行星架402还与所述制动器601的主动端固定连接；所述第二行星太阳轮401通过第四连接部1204与所述第二电动机5的第二转子501固定连接；所述第二转子501的外侧同轴设置有第二定子502，所述第二定子502固定在变速器壳体8上。
所述发动机1、第一电动机2、第一行星齿轮组3、第二行星齿轮组4和第二电动机5通过制动器601、第一离合器602和第二离合器603的接合或分离实现多种动力输出模式，以下对本发明实施例多种工况下的动力输出模式举例说明：
1、一般城市工况下
车辆由第二电动机5启动，将制动器601结合，此时，第一行星内齿圈303和第二行星架402静止不动，第二电动机5的扭矩由第二转子501依次经第四连接部1204、第二行星太阳轮401、第二行星内齿圈403和第一行星架302传递到输出齿轮1101，再依次经第一中间齿轮1102、第二中间齿轮1103和第三中间齿轮1104传递到差速器1105，最后经差速器1105传递到车轮。第二行星齿轮组4由第二行星太阳轮401到第二行星内齿圈403的速比可为3到3.5，加上输出轴主减速比(从第一行星架301传递到差速器1105的速比)为2.5到3，驱动总速比可为7.5到10.5之间，满足一般混合动力汽车城市路况行驶要求。
2、城市工况下高速运行时
车辆由所述第二电动机5启动，将制动器601脱开、第一离合器602结合，此时，第一行星齿轮组3和第二行星齿轮组4互相锁死，第二电动机5的扭矩1:1输出到第一行星架302，再加上输出轴主减速比2.5到3，电机驱动总速比即为2.5到3，更加节能高效。高速工况下制动时，为避免能源浪费，将第二离合器603结合，扭矩依次经第一行星太阳轮301和内输入轴9传递到第一转子201，第一转子201转动，带动第一电动机2发电，实现能源回收。
3、山区路况或上坡启动时
山区路况或上坡启动时，需要较大扭矩，将所述制动器601和第二离合器603结合时，第一离合器602断开，车辆由所述发动机1、第一电动机2和第二电动机5同时施加扭矩。一方面，发动机1和第一电动机2的动力依次经内输入轴9和第一行星太阳轮301传递到第一行星架302；另一方面，第二电动机5的动力由第二转子501依次经第四连接部1204、第二行星太阳轮401和第二行星内齿圈403传递到第一行星架302，以上两方面动力耦合后传递到输出齿轮1101，再依次经第一中间齿轮1102、第二中间齿轮1103和第三中间齿轮1104传递到差速器1105，最后经差速器1105传递到车轮。
第二行星齿轮组4由第二行星太阳轮401到第二行星内齿圈403的速比可为3到3.5；第一组行星齿轮3由第一行星太阳轮301到第一行星架302的速比可为4到4.5，以上两方面耦合后加上输出轴主减速比(从第一行星架301传递到差速器1105的速比)2.5到3，达到减速减速增扭的效果。
4、行驶超车时
将制动器601脱开、第一离合器602和第二离合器603结合，一方面，第二电动机5的扭矩1:1输出到所述第一行星架302；另一方面，发动机1和第一电动机2的扭矩依次经内输入轴9和第一行星太阳轮301传递到第一行星架302；两方面动力耦合后传递到输出齿轮1101，实现增扭超车，提供更佳的动力性。
5、ECVT模式
将制动器601脱开，第一离合器602脱开，第二离合器603结合，当发动机1和发电机4的转速恒定时，通过调整第二电动机5的转速实现ECVT模式，理论上可提供2到20的速比区间。实际应用时用来填补上述一档和二档间的速比过渡，换档更平滑，提高了驾驶舒适性。
本发明实施例还提供了一种汽车，包括车身、底盘及权利要求1-9任一项以上所述的混合动力车辆传动系统，所述混合动力车辆传动系统设置在底盘上
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
