Description

一种汽车电动真空泵
技术领域
本发明属于汽车制动系统领域，尤其是指一种新型汽车电动真空泵。
背景技术
现阶段在电动真空泵行业中，泵室密封环与O型密封圈采用分体式设计，密封环装配在下盖板与电机之间，会出现装配不准导致挤压变形，在电动真空泵工作时存在抽入真空通道或真空泄漏的情况，O型密封圈由于直径与其截面直径比率较大，在自由状态下会发生圈曲、变形等现象，O型密封圈装配到消音盖与电机间的异型环槽中，易出现脱出情况。由于现有结构防错设计不足，会出现零件漏装、装配不到位等问题，使车辆制动系统安全性大大降低的风险。
发明内容
本发明提供一种汽车电动真空泵，以解决现有电动真空泵的密封环和O型密封圈易发生变形，导致电动真空泵工作时抽入真空通道或真空泄漏及O型密封圈易出现脱出，零件出现漏装、装配不到位的问题。
本发明采取的技术方案是：消音盖通过颗消音盖螺钉装配在电机上，泵室螺钉将上盖板、定子、下盖板固定在电机上，在定子内部安装转子、叶片和偏心环，其中五片叶片安装在转子的五个槽中，偏心环与电机的电机轴过盈配合，转子安装在偏心环上，异型密封圈安装在电机与消音盖以及电机与下盖板之间，防护罩固定连接在电机侧面，支撑套与减震套孔内部固定连接，减震套固定连接在电机的法兰耳孔处，密封塞安装在电机底部；
所述异型密封圈内部为“8”字型，外部为异型，外部与内部由三根筋连接；
所述电机上有法兰结构，法兰中的密封圈槽为异型，密封圈槽与异型密封圈相匹配，法兰上有圆台，圆台与下盖板相匹配。
本发明的优点在于：结构新颖，在消音盖、与电机之间，下盖板与电机之间，设置明密封圈，将电机与下盖板之间的密封结构，以及电机与消音盖之间的密封结构统一为一个密封结构；在法兰中设置与新结构密封圈配合的密封槽，下盖板与新结构密封圈有更多的橡胶接触部位，能够更多的降低下盖板振动，抑制下盖板产生的噪音；将密封环和O型密封圈通过连接筋结合，由于增加连接筋结构，O型密封圈能够区分装配方向，可以与电机的异型密封圈槽一致，能够大大减低密封圈脱出的风险。采用一体式结构后，零件装配为工艺简化为装配一次，提高了产品的装配效率，用于新能源汽车、带有涡轮增压系统发动机的汽车、柴油发动机的汽车中，起到为汽车真空制动系统提供真空源的作用，属于汽车制动系统中的安全件之一。
附图说明
图1是本发明的爆炸图；
图2是本发明密封圈的结构示意图；
图3是本发明电机的结构示意图；
图中，消音盖1、泵室螺钉2、上盖板3、转子4、叶片5、偏心环6、定子7、消音盖螺钉8、下盖板9、异型密封圈10、电机11、防护罩12、减振套13、支撑套14、密封塞15、法兰1101、异型密封圈槽110101、圆台110102。
具体实施方式
消音盖1通过3颗消音盖螺钉8装配在电机11上，泵室螺钉2将上盖板3、定子7、下盖板9固定在电机11上，在定子7内部安装转子4、叶片5和偏心环6，其中五片叶片5安装在转子4的五个槽中，偏心环6与电机11的电机轴过盈配合，转子4安装在偏心环6上，异型密封圈10安装在电机11与消音盖1以及电机11与下盖板9之间，防护罩12固定连接在电机11侧面，支撑套14与减震套13孔内部固定连接，减震套13固定连接在电机11的法兰耳孔处，密封塞15安装在电机底部；
所述异型密封圈10内部为“8”字型，外部为异型，外部与内部由三根筋连接；
所述电机11上有法兰1101结构，法兰1101中的密封圈槽110101为异型，密封圈槽110101与异型密封圈10相匹配，法兰1101上有圆台110102，圆台110102与下盖板9相匹配。
工作原理：本发明的电动真空泵由上盖板3、定子7和下盖板9形成密闭泵室，在电机11的驱动下，通过偏心环6带动转子4转动，叶片5在离心力作用下将泵室内气体排出产生真空。消音盖1的主要作用是减小噪音，保护内部不受灰尘和水、油等杂质侵扰。异型密封圈10安装在电机11上，起到电机11与消音盖1之间的密封，防止杂质侵扰。同时，在电机11与下盖板9之间有一处进气通道，起到密封作用。
本发明的异型密封圈10，如图2所示。内部由一个“8”字型密封圈组成，外部是一个异型密封圈，外部与内部由3根筋连接。通过上述结构组合后，异型密封圈的装配状态稳定，不易变形。在装配过程中不易松脱。本发明的异型密封圈10因结构上发生的变化，增大了与下盖板9的接触面积，且异型密封圈10与下盖板9的接触部分相对原方案受力更加均布,使得橡胶减振抑制噪音的能力提高，有效降低了产品的整体噪音水平。
