Description

新型混合动力耦合机构及机动车辆
技术领域
本发明涉及混合动力汽车技术领域，特别涉及一种新型混合动力耦合机构及机动车辆。
背景技术
动力***包括发动机(内燃机)和一个由变速器、差速器和传动轴组成的传动***。它的作用是向车辆提供驱动轮所需的驱动动力。内燃机有一定的速度和扭矩范围，并在其中很小的范围内达到最佳的工作状态，这时或是油耗最小，或是有害排放最低，或是俩者皆然。然而，实际路况***，不但表现在驱动轮的速度上，同时还表现在驱动轮所要求的扭矩。因此，实现内燃机的转速和扭矩最优，即动力最优状态，与驱动轮动力状态之匹配好，是变速器的首要任务。
目前市场上的变速器主要有有级变速器和无级变速器两大类。有级变速器又细分为手动和自动两种，它们大多通过齿轮系或行星轮系不同的啮合排列来提供有限个离散的输出输入速比，两相邻速比之间驱动轮速度的调节则依靠内燃机的速度变化来实现；无级变速器，无论是机械式，液压式，或机一电式的，都能在一定速度范围内提供无限个连续可选用的速比，理论上说，驱动轮的速度变化完全可通过变速器来完成。这样，内燃机可以尽可能的工作在最佳速度范围内。同时无级变速器和有级变速器相比，具有调速平稳，能充分利用内燃机最大功率等诸多优点，因此，无级变速器多年来一直是各国工程师们研究的对象。
近年来，电机混合动力技术的诞生为实现内燃机与动力轮之间动力的完全匹配开拓了新的途径。在众多的动力总成设计案中，最具代表性的有串联混合***和并联混合***两种。电机串联混合***中，内燃机--发电机--电动机--轴系--驱动轮组成一条串联的动力链，动力总成结构极为简单。其中，发电机--电动机组合可视为传统意义下的变速器。而对于电机并联***，其具有两条并行的独立的动力链，一条由传统的机械变速器组成，另一条由电机--电池***组成，机械变速器负责完成对速度的调节，而电机--电池***则完成对功率或扭矩的调节，为充分发挥整个***的潜能，机械变速器还需采用无级变速方式，结构较复杂。在并联混合***中，只有部分动力通过电机***，因此对电机的功率要求相对较低，整体***的效率高。然而，此***需两套独立的子***，造价高，通常只用于弱混合***。而串联混合***的优点在于结构简单，布局灵活。但由于全部动力通过发电机和电动机，因此电机的功率要求高，体积大，重量重。同时，由于能量传输过程经过两次机--电、电--机的转换，整个***的效率较低。

所述新型混合动力耦合机构包含一个发动机、两个电机、一个单行星排齿轮机构、一个复合行星排齿轮机构及轴齿***等。通过两个行星排齿轮机构(即所述单行星排齿轮机构200和复合行星排齿轮机构500)将两个电机(即所述发电机710和驱动电机610)和发动机110进行连接，从而可通过两个电机有效的补充动力轮所需的驱动动力，更合理地调配所述发动机110的动力，保持所述发动机110的工作状态不受或少受路况的影响，使得所述发动机110可始终工作在设定的最佳状态，以提高整个***的效率，大幅度地提高整个***的燃油效率。而且，所述发动机110和发电机710通过两个行星排齿轮机构进行连接，速比可调，速比范围较大，可以减小所述发电机710的体积；而且，在混合动力模式下，可以通过两个行星排齿轮机构调速，优化所述发动机110的工作区间，提高所述发动机710的经济性能；而且，所述驱动电机610通过行星排齿轮机构(即所述复合行星排齿轮机构500)连接输出，可以增加所述驱动电机610的速比，有利于电机的高速化，从而可以减小电机体积，有利于节省空间和轻量化。
此外，如图2至图3所示，所述新型混合动力耦合机构具有纯电动驱动模式，在纯电动驱动模式下，所述第二制动器570锁止所述第二行星架510，这样使得所述第二行星架510无法转动，所述离合器300也与所述第一输入轴130分离，此时所述发动机110的动力无法通过所述中间输入轴400和所述第二行星架510进行传递，只能通过所述驱动电机610和发电机710驱动所述复合行星排齿轮机构500，实现纯电力电动输出。
而且，如图2所示，当只有所述驱动电机610工作时，所述驱动电机610通过所述第三输入轴620驱动所述复合行星排齿轮机构500，所述新型混合动力耦合机构实现单电机电动驱动模式。此时，所述第三输入轴620驱动所述第三太阳轮540转动，从而驱动所述第三行星轮550自转，以此驱动所述第二齿圈560转动，从而通过所述第二齿圈560驱动所述动力输出机构运动，从而实现单电机纯电动驱动模式。此外，如图3所示，当所述驱动电机610和发电机710同时工作时，所述驱动电机610通过所述第三输入轴620驱动所述复合行星排齿轮机构500，同时所述发电机710通过所述第二输入轴720驱动所述复合行星排齿轮机构500，实现双电机纯电动驱动模式。此时，不仅所述第三输入轴620驱动所述第三太阳轮540转动，所述第二输入轴720也会驱动所述第二太阳轮520转动以驱动所述第二行星轮530自转，从而可以使所述第三太阳轮540和第二行星轮530同时驱动所述第三行星轮550自转，以此驱动所述第二齿圈560转动，从而通过所述第二齿圈560驱动所述动力输出机构运动，从而实现双电机纯电动驱动模式。通过单电机纯电动驱动模式和双电机纯电动驱动模式的切换，可以实现纯电动驱动下的速比可调。
此外，如图4至图5所示，所述新型混合动力耦合机构具有混合驱动模式，即所述发动机110和驱动电机610同时进行驱动的模式。在混合驱动模式下，所述发动机110可以对所述复合行星排齿轮机构500进行驱动，同时所述驱动电机610也可以对所述复合行星排齿轮机构500进行驱动。具体地，如图4所示，当所述离合器300与所述第一输入轴130啮合时，所述第一输入轴130通过所述离合器300直接与所述中间输入轴400连接，从而使得所述发动机110能够直接通过所述第一输入轴130驱动所述复合行星排齿轮机构500的第二太阳轮520进行转动，从而带动所述第二行星轮530及第三行星轮550进行转动，以实现对所述第二齿圈560的驱动，从而对所述动力输出机构进行发动机驱动；同时，所述驱动电机610通过所述第三输入轴620对所述第三太阳轮540进行驱动，所述第三太阳轮540也会驱动所述第三行星轮550转动，所述第三行星轮550又驱动所述第二齿圈560转动，又可以实现对所述动力输出机构的电动驱动。这样，就可以同时实现对所述动力输出机构的发动机驱动和电动驱动，即实现了对所述新型混合动力耦合机构的混合驱动。此外，如图5所示，当所述离合器300与所述第一输入轴130分离时，所述第一输入轴130对所述第一行星架230进行转动驱动，所述第一行星架230会带动所述第一行星轮220绕着所述第一太阳轮210转动，从而使得所述第一行星架230对所述第一齿圈240进行驱动，而所述第一齿圈240会带动所述第二行星架510转动，从而使得所述发动机110能够通过所述单行星排齿轮机构200驱动所述复合行星排齿轮机构500的第二行星架510进行转动，从而带动所述第三行星轮550进行转动，以实现对所述第二齿圈560的驱动，从而对所述动力输出机构进行发动机驱动；同时，所述驱动电机610也通过所述第三输入轴620对所述第三太阳轮540进行驱动，所述第三太阳轮540也会驱动所述第三行星轮550转动，所述第三行星轮550又驱动所述第二齿圈560转动，又可以实现对所述动力输出机构的电动驱动。这样，也可以同时实现对所述动力输出机构的发动机驱动和电动驱动，即实现了对所述新型混合动力耦合机构的混合驱动。即，所述发动机110通过所述离合器300使所述第一输入轴130或单行星排齿轮机构200驱动所述复合行星排齿轮机构500，同时所述驱动电机610通过所述第三输入轴620驱动所述复合行星排齿轮机构500，以实现混合驱动，而且还可以通过所述离合器300和制动器对输出速比进行调节。
而且，在混合驱动模式下，所述发电机710可用来启动所述发动机110。此外，在混合驱动模式下，所述第二行星轮530会在所述第二行星架510的带动下转动，从而会带动所述第二太阳轮520转动，这样会反过来带动所述第二输入轴720转动，从而可以使得所述发电机710进行发电。而且，还可以将发电的电能进行储存备用或者传输给所述驱动电机610使用。
此外，如图6至图9所示，所述新型混合动力耦合机构具有发动机直驱模式，即仅仅利用所述发动机对所述动力输出机构进行驱动，而所述发电机710和驱动电机610均不输出动力，但是所述发电机710可用来启动所述发动机110。在发动机直驱模式下，可利用所述第三制动器630锁止所述第三输入轴620，或者利用所述第一制动器410锁止所述第二输入轴720，或者利用所述第二制动器570锁止所述第二行星架510，从而使得所述第三太阳轮540固定不动，或者使所述第二太阳轮520固定不动，或者使所述第二行星架510固定不动。
而且，如图6至图7所示，所述第三制动器630锁止所述第三输入轴620，且当所述第一输入轴130与所述离合器300啮合时，所述第一输入轴130直接通过所述中间输入轴400驱动所述复合行星排齿轮机构500，此时可以实现所述发动机110的一档直驱模式。具体地，所述离合器300与所述第一输入轴130啮合，使得所述第一输入轴130通过所述离合器300直接与所述中间输入轴400连接，从而使得所述发动机110能够直接通过所述第一输入轴130驱动所述复合行星排齿轮机构500的第二太阳轮520进行转动，从而带动所述第二行星轮530及所述第三行星轮550)进行转动，以实现对所述第二齿圈560的驱动，从而对所述动力输出机构进行发动机驱动。而且，当所述第一输入轴130与所述离合器300分离时，所述单行星排齿轮机构200通过所述第一齿圈240驱动所述第二行星架510及所述复合行星排齿轮机构500，此时可以实现所述发动机110的二档直驱模式。具体地，所述离合器300与所述第一输入轴130分离，使得所述第一输入轴130对所述第一行星架230进行转动驱动，所述第一行星架230会带动所述第一行星轮220绕着所述第一太阳轮210转动，从而使得所述第一行星架230对所述第一齿圈240进行驱动，而所述第一齿圈240会带动所述第二行星架510转动，即使得所述发动机110能够通过所述单行星排齿轮机构200驱动所述复合行星排齿轮机构500的第二行星架510进行转动，从而带动所述第三行星轮550(绕着第三太阳轮540)进行转动，以实现对所述第二齿圈560的驱动，从而对所述动力输出机构进行发动机驱动。
此外，如图8至图9所示，当所述第二制动器730锁止所述第二行星架510，且所述第一输入轴130与所述离合器300啮合时，所述第一输入轴130直接通过所述中间输入轴400驱动所述复合行星排齿轮机构500，此时可以实现所述发动机110的三档直驱模式。具体地，所述离合器300与所述第一输入轴130啮合，使得所述第一输入轴130通过所述离合器300直接与所述中间输入轴400连接，从而使得所述发动机110能够直接通过所述第一输入轴130驱动所述复合行星排齿轮机构500的第二太阳轮520进行转动，从而带动所述第二行星轮530进行转动，并带动所述第三行星轮550转动，从而实现对所述第二齿圈560的驱动，以此对所述动力输出机构进行发动机驱动。此外，当所述第一制动器410锁止所述中间输入轴400及第二输入轴720时，且所述第一输入轴130与所述离合器300分离时，所述单行星排齿轮机构200通过所述第一齿圈240驱动所述第二行星架510及所述复合行星排齿轮机构500，此时可以实现所述发动机110的四档直驱模式。具体地，所述离合器300与所述第一输入轴130分离，使得所述第一输入轴130对所述第一行星架230进行转动驱动，所述第一行星架230会带动所述第一行星轮220绕着所述第一太阳轮210转动，从而使得所述第一行星架230对所述第一齿圈240进行驱动，而所述第一齿圈240会带动所述第二行星架510转动，即使得所述发动机110能够通过所述单行星排齿轮机构200驱动所述复合行星排齿轮机构500的第二行星架510进行转动，从而带动所述第二行星轮530进行转动，并带动所述第三行星轮550转动，从而实现对所述第二齿圈560的驱动，从而对所述动力输出机构进行发动机驱动。这样，就可以通过所述单行星排齿轮机构200和复合行星排齿轮机构500实现所述发动机的四挡速比可调，***模式多效率高，经济性好。
