Description

一种新型节气门体
技术领域
本发明涉及汽车零部件领域，尤其是一种新型节气门体。
背景技术
现有技术中，具有圆筒状的节气门体，配置拉线结构驱动单片内置式挡片调节节气门开度，在挡片另一端安装角度传感器来测量节气门的开度作为控制信号。
上述节气门的挡片基本上位于进气道的正中央位置，会使进气气流产生扰动，在稳压腔中产生漩涡，不利于气流的稳定，相应的进气量就会减少，并且相同条件下会有更大的进气阻力，这些都会降低进气效率，对发动机产生不利影响。
发明内容
本发明所要解决的技术问题在于，提供一种结构合理的节气门体，大大减小了节气门的尺寸，稳定进气气流，提高进气量，提高发动机功率和燃油利用效率。
为解决上述技术问题，本发明提供一种新型节气门体，包括电机1、上底板2、叶片3、驱动圈4、下底板5；电机1固定于上底板2上，驱动圈4放置于下底板5的圈槽中，叶片3通过其上的凹台安装于驱动圈4的长槽和上底板2、下底板5的圆孔中，上底板2和下底板5通过螺栓安装，整个装置装为一体。
优选的，驱动圈4上有齿，电机1驱动驱动圈4上的齿。
优选的，节气门体直接采集电机1的位置信号作为节气门的开度信号。
本发明的有益效果为：大大缩小了节气门体的长度与体积，对进气系统的布置要求较低；采用多叶片旋转结构直接控制进气道直径的大小，在进气道中没有阻碍气流的挡片，不会产生气流扰动，稳定了气流，提高了进气压力，提高发动机的输出功率和燃油利用率。
附图说明
图1是本发明的整体结构示意图。
图2是本发明的装配整体示意图。
1、电机；2、上底板；3、叶片；4、驱动圈；5、下底板。
具体实施方式
如图1和2所示，一种新型节气门体，包括电机1、上底板2、叶片3、驱动圈4、下底板5；电机1固定于上底板2上，驱动圈4放置于下底板5的圈槽中，叶片3通过其上的凹台安装于驱动圈4的长槽和上底板2、下底板5的圆孔中，上底板2和下底板5通过螺栓安装，整个装置装为一体。
驱动圈4上有齿，电机1通过驱动驱动圈4上的齿来使驱动圈4进行旋转，从而达到耳片开闭的目的。
本发明的节气门体具有多叶片旋转式的开闭结构，配置的叶片由电机驱动，叶片直接旋转产生开闭效应，直接控制叶片处管道直径的大小，使得进气气流在节气门处能够平稳，并且具有更小的局部阻力。
本发明的节气门中，直接采集电机位置信号作为节气门的开度信号，去除了传统的相位传感器作为输出信号，进一步的减小了节气门的体积。
本发明的上底板和下底板均有叶片旋转时的定位孔，下底板有用于安装驱动圈的槽，用于驱动圈的旋转运动。
驱动圈上有安装叶片的孔，用于驱动叶片做旋转运动从而控制节气门开闭，并且驱动圈上有齿，用于和电机齿轮啮合。
尽管本发明就优选实施方式进行了示意和描述，但本领域的技术人员应当理解，只要不超出本发明的权利要求所限定的范围，可以对本发明进行各种变化和修改。
