Description

混合动力驱动***
技术领域
本发明涉及新能源技术领域，特别涉及一种混合动力驱动***。
背景技术
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、电式，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方案中，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。当与储能器，如电池，电容等联合使用时，该变速器又可作为能量调节装置，完成对速度和扭矩的独立调节。
电机并联***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。
串联混合***的优点在于结构简单，布局灵活。但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。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***。
