Description

一种卡车冷却与噪音平衡控制系统及控制方法 技术领域
本发明属于发动机噪音管理系统技术领域，特别是指一种卡车冷却与噪音平衡控制系统及控制方法。
背景技术
通常为了解决卡车噪音问题，降低噪音，采用在发动机和冷却系统周围布置消音棉的方法降低来自发动机内部的曲柄连杆运动机构的噪音和冷却系统的噪音(冷却系统噪音主要由冷却风扇产生；在散热器大小确定的情况下，通常采用加大风扇转速的方法来提升散热效果，发动机冷却液水温越高，风扇转速越高)
如图1所示为不加消音棉的常规状态示意图；图2为增加消音棉的状态示意图；发动机01及冷却散热器03均固定于车架04上，在发动机与冷却散热器之间设置有冷却风扇02。
采用此技术方式虽然能够对整车噪音进行有效消除，但是在一定程度上对发动机冷却产生了负面影响。由于被大量消音棉05包围，发动机自身和冷却散热器对外的热辐射也相应被阻挡，同时，由冷却风扇转动产生的流动风场受到阻挡，从冷却散热器经过后的热风无法及时从发动机仓吹出，热风聚集在散热器和发动机周围，对冷却系统造成很大压力。

多个调节扇叶片转动设置于长方形外框内；第一电机和第二电机分别固定于长方形外框的两侧，其中第一电机固定于长方形外框的左侧，第二电机固定于长方形外框的右侧。
在长方形外框的上部固定有外护罩，第一电机用于控制部分的调节扇叶片转动，第二电机用于控制另一部分的调节扇叶片的转动。

在上横梁的上表面设置有两条平行的齿条下轨道116；第一齿条与第二齿条相对滑动设置于两条齿条下轨道内，第三齿条与第四齿条滑动设置于两条齿条下轨道内，其中，第一齿条与第三齿条相邻，滑动设置于同一条齿条下轨道内，第二齿条与第四齿条相邻，滑动设置于另一条齿条下轨道内。
两条齿条下轨道均不贯通上横梁的两端。
如图13所示，第一齿条、第二齿条、第三齿条及第四齿条的结构相同，均为长方体的齿条本体161，在齿条本体的一个侧面设置有一排齿形结构162，该齿形结构与第一联动齿轮的齿、第二联动齿轮的齿啮合配合。
如图9和图10所示，调节扇叶片12包括长方形叶片框121、消音棉层122、下转轴123、上转轴124及第一联动齿轮125。长方形叶片框为框架形结构，在框架形结构靠近发动机的一侧设置有消音棉层，这样框架结构同时对消音棉层起到支撑作用。
消音棉层设置于长方形叶片框上；在长方形叶片框的下方设置有下转轴，在长方形叶片框的上方设置有上转轴，第一联动齿轮设置于上转轴的端部。
第一电机与第二电机的结构相同，均包括电机输出轴，在电机输出轴的端部设置有第二联动齿轮141，具体为，第一电机的输出轴穿过第一电机转轴孔 后，第二联动齿轮固定于电机输出轴上端；第二电机的输出轴穿过第二电机转轴孔后，用于第二电机上的第二联动齿轮固定于电机输出轴的上端。
如图8、图15、图16所示为移除外护罩后的左侧调节扇总成，第一联动齿轮、第二联动齿轮、第一齿条、第二齿条、第三齿条及第四齿条均位于上横梁的上表面，且第一联动齿轮与第二联动齿轮分别位于第一齿条与第二齿条之间或第三齿条与第四齿条之间，第一电机转动带动第二联动齿轮转动，第二联动齿轮带动第一齿条及第二齿条作相反方向滑动，即第一齿条向左滑动时，第二齿条向右滑动，第一齿条第二齿条的动作带动第一联动齿轮的转动，进而带动调节扇叶片的转动，实现调节扇叶片转动设定角度的目的。
同样道理，第二电机转动带动第三齿条与第四齿条作相反方向滑动，即第三齿条向左滑动时，第四齿条向右滑动，第三齿条与第四齿条的动作带动其间的第一联动齿轮的转动，进而带动部分的调节扇叶片的转动。
如图14所示，外护罩13包括护罩上顶面131及护罩上顶面两侧的外罩侧面132；在护罩上顶面的下表面设置有两条平行的齿条上轨道133；两条齿条上轨道与两条齿条下轨道一一相对设置。在外罩侧面上设置有与上横梁固定的安装孔。
如图17所示，为两个电机均未工作时，调节扇叶片处于初始设定的角度位置θ处。
如图18所示，两个电机反向同步转动，调节扇叶片随着转动，调节扇叶片开启角度加大，最大时θ＝90°。
如图19所示，两个电机反向同步转动时，调节扇叶片随着转动，调节扇叶片开启角度减小，最小为θ＝0°。
左侧调节扇叶、右侧调节扇叶及后部调节扇叶均预设开启角度θ，θ小于30度，在本申请的其它实施例中，角度θ值可以通过噪音与热平衡通过计算得到。角度θ为上述的左侧调节扇叶与左侧调节风扇组所在平面的夹角，或右侧调节扇叶与右侧调节风扇组所在平面的夹角，或后部调节扇叶与后部调节风扇组所在平面的夹角。
本技术方案还提供上述任一项卡车冷却与噪音平衡控制系统的控制方法，包括以下步骤：
在控制器内预设理想的车辆噪音水平范围值Aa和Ab，其中Ab大于Aa；
同时，在控制器内预设冷却系统处于理想工作状态时的风扇转速范围Na和Nb，其中Nb大于Na。
左侧调节扇叶、右侧调节扇叶及后部调节扇叶均预设开启角度θ，θ的角度小于30度。
第一噪音传感器将实时采集的噪音信号A1传递给控制器，第二噪音传感器将实时采集的噪音信号A2传递给控制器；转速传感器将采集的实时冷却风扇的转速信号N0传递给控制器。
控制计算噪音信号A1和噪音信号A2的平均值A0，并与Aa和Ab进行比较；同时控制器将采集到的冷却风扇转速信号N0与Na和Nb进行比较。
当A0处于Aa和Ab范围之间时，且N0处于Na和Nb范围之间时，此时车辆的噪音和冷却状况均能够满足设定要求，控制器控制左侧调节扇叶、右侧调节扇叶及后部调节扇叶均处于预设开启角度θ状态。
当A0大于Ab时，但是N0处于Na和Nb范围之间，此时车辆的噪音状况不能满足理想状态，但是冷却状况能够符合理想状态，控制器控制左侧调节风扇组中的左侧电机带动左侧调节扇叶开启角度均为θ1，控制器控制右侧调节风扇组中的右侧电机带动右侧调节扇叶的开启角度也为θ1，θ1小于θ；以使得A0处于Aa和Ab范围之间，后部调节扇叶的开启角度保护为θ。
当A0大于Ab时，且N0大于Nb时，此时，车辆的噪音及冷却状况均不符合理想状态，控制器控制左侧调节风扇组中的左侧电机带动左侧调节扇叶开启角度均为θ2，控制器控制右侧调节风扇组中的右侧电机带动右侧调节扇叶的开启角度也为θ2，控制器控制后部调节风扇组的后部电机带动后部调节扇叶的开启角度为θ3；θ2小于θ，θ3大于θ；使得A0处于Aa和Ab范围之间，N0处于Na和Nb范围之间。
当A0处于Aa和Ab范围之间时，但是N0大于Nb时，此时车辆的冷却状况不符合理想状态；控制器控制左侧调节扇叶及右侧调节扇叶的开启角度为θ，控制器控制后部调节扇叶的开启角度为θ4，θ4大于θ。
θ1和θ2可以相等也可以不相等；θ3和θ4可以相等也可以不相等。在本申请中，θ1、θ2、θ3及θ4的夹角均是相应侧调节扇叶与相应侧的调节 风扇组所在平面的夹角。
尽管已经对本发明的技术方案进行了详细的描述，但是本领域的技术人员均清楚，通过对本技术方案进行的修改、替换及修饰等，均应当在本申请的保护范围之内。
