Abstract

一种无级变速器夹紧力控制方法主要是根据传动效率的反馈情况来进行夹紧力的控制，首先使用常用方法以较大的目标夹紧力实现无级变速器的夹紧力控制，然后以一定的偏差减小夹紧力，同时根据主动轮转速、从动轮转速、主动轮转矩、从动轮转矩计算无级变速器的传动效率，如果夹紧力减小后无级变速器传动效率有所增加则继续减小夹紧力；如果夹紧力减小后传动效率反而下降则以刚才较大的传动效率对应的夹紧力为最佳夹紧力，来进行无级变速器的夹紧力控制。无级变速器夹紧力控制方法可以使无级变速器始终保持较高的传动效率；而且与其它控制方法相比，控制方法比较简单。

Description

一种无级变速器夹紧力控制方法
技术领域
本发明涉及一种无级变速器夹紧力控制方法，具体的说是一种金属带式无级变速器的夹紧力控制方法。
背景技术
金属带式无级变速器相对于有级变速器，能在全速比范围内使发动机工作在最佳经济工况点，从而有效降低燃油消耗和排放，且驾驶舒适性好。
但无级变速器传动效率偏低，一个主要原因就是金属带夹紧力的控制问题，夹紧力过大，将增加金属带与带轮径向滑动引起的摩擦损失等，降低传动效率；如果夹紧力过小，金属带则会在带轮上打滑，增加金属带与带轮的摩擦损失，无法保证转矩的可靠传递，同样会降低传动效率。
在夹紧力控制中，一般取安全系数1.3，以保证金属带在任何工况下不打滑，而过大的夹紧力不仅使机械传动效率降低，而且增加了液压控制系统的能耗。
发明内容
本发明的目的在于提出一种无级变速器夹紧力控制方法，通过采集转速和转矩信号，计算无级变速器传动效率，根据传动效率的反馈情况来进行夹紧力的控制，提高无级变速器的传动效率。
本发明的目的可以通过以下技术方案来实现：
无级变速器夹紧力控制方法主要是通过采集转速和转矩信号，计算无级变速器传动效率，根据传动效率的反馈情况来进行夹紧力的控制。
在原有的无级变速器夹紧力控制系统中，已有主动轮转速传感器、从动轮转速传感器、电子控制单元、夹紧力液压调节装置等，再分别在主动轮、从动轮上增加转矩传感器，重新构建夹紧力控制系统。
主动轮转速传感器、从动轮转速传感器分别测量主动轮转速、从动轮转速。
主动轮转矩传感器、从动轮转矩传感器分别测量主动轮转矩、从动轮转矩。
电子控制单元采集主动轮的转速信号、转矩信号，从动轮的转速信号、转矩信号，计算无级变速器传动效率，根据传动效率的反馈情况来进行夹紧力的控制。
夹紧力液压调节装置根据电子控制单元的指示实现对夹紧力的调节。
本发明的优点为：无级变速器夹紧力控制方法主要是根据传动效率的反馈情况来进行夹紧力的控制，既可以防止夹紧力过大，导致消耗过多传动能量传动效率降低，又可以防止夹紧力过小，导致金属带打滑传动效率降低，进而使无级变速器始终保持较高的传动效率；而且与其它控制方法相比，夹紧力控制方法比较简单。
附图说明
图1为无级变速器夹紧力控制方法示意图。
具体实施方式
无级变速器传动效率偏低的一个主要原因就是金属带夹紧力的控制问题，在夹紧力控制中，一般取安全系数1.3，以保证金属带在任何工况下不打滑，但是传动效率降低，无级变速器夹紧力控制方法主要是根据传动效率的反馈情况来进行夹紧力的控制。
无级变速器夹紧力控制方法需要重新构建无级变速器夹紧力控制系统，在已有的主动轮转速传感器、从动轮转速传感器、电子控制单元、夹紧力液压调节装置基础上，分别在主动轮、从动轮上增加转矩传感器，形成新的无级变速器夹紧力控制系统。
主动轮转速传感器、从动轮转速传感器分别测量主动轮转速、从动轮转速，用于无级变速器传动效率的计算使用。
电子控制单元采集主动轮的转速信号、转矩信号，从动轮的转速信号、转矩信号，计算无级变速器传动效率，根据传动效率的反馈情况，向夹紧力液压调节装置发出调节无级变速器夹紧力大小的信号。
夹紧力液压调节装置根据电子控制单元的指示调节压力调节阀控制压力，实现对无级变速器夹紧力大小的调节。
增加的主动轮转矩传感器、从动轮转矩传感器分别安装在主动轮、从动轮转轴上，测量主动轮转矩、从动轮转矩，用于无级变速器传动效率的计算使用。
主动轮转速传感器、从动轮转速传感器、主动轮转矩传感器、从动轮转矩传感器分别测量主动轮转速、从动轮转速、主动轮转矩、从动轮转矩，并将信号传递给电子控制单元；电子控制单元首先使用常用方法以较大的目标夹紧力实现无级变速器的夹紧力控制，然后以一定的偏差减小夹紧力，同时根据采集的上述信号计算无级变速器的传动效率，如果夹紧力减小后无级变速器传动效率有所增加则继续以一定的偏差减小夹紧力，如果夹紧力减小后传动效率反而下降则以刚才较大的传动效率对应的夹紧力为最佳夹紧力，来进行无级变速器的夹紧力控制。
本发明还可以有其它实施方式，凡采用同等替换或等效变换形成的技术方案，均落在本发明要求保护的范围之内。
