Description

油压减振器
技术领域
本发明涉及一种减振器，尤其是一种油压减振器。
背景技术
随着汽车技术的不断发展进步，人们对汽车驾驶和乘坐的舒适性要求越来越高，而汽车发动机在运行过程中产生的振动和噪声是影响汽车驾驶和乘坐舒适性的一个重要因素。车辆运行速度的不断提高使汽车运行时所产生的振动也相应加剧。这就对车辆的减振性能也提出了更高的要求。油压减振器可以吸收车辆的振动，因此油压减振器的性能直接影响着车辆的舒适性甚至运行的安全性。现有的油压减振器实际运行过程中经常会出现漏油的现象，油液是油压减振器传递阻尼的介质，油液泄漏会直接影响减振器的性能，使油压减振器性能恶化，甚至失效。
发明内容
针对现有技术中存在的不足，本发明提供一种油压减振器，能够有效防止油液外泄。本发明采用的技术方案是：
一种油压减振器，包括安装支架、金属块、橡胶主簧、金属骨架、上惯性通道、下惯性通道、皮碗底座、解耦膜片、皮碗；
皮碗安装在皮碗底座内，所述皮碗底座与皮碗配合，皮碗外圈凸起，形成密封圈与下惯性通道紧密贴合；皮碗上方形成下腔；
橡胶主簧内部镶嵌金属骨架和金属块；金属块位于橡胶主簧上部中间，金属骨架位于橡胶主簧下部一圈；橡胶主簧的下方形成上腔；
安装支架、橡胶主簧和皮碗底座连接成整体；
上惯性通道和下惯性通道设置在橡胶主簧与皮碗之间的腔体内；上惯性通道和下惯性通道上均设有油通孔；解耦膜片位于上惯性通道和下惯性通道中间。
进一步地，安装支架、橡胶主簧和皮碗底座边缘均具有凸缘，且各自凸缘上设有相对应的固定孔，通过螺钉穿过安装支架、橡胶主簧和皮碗底座上的凸缘进行锁紧。
进一步地，金属块中间开有螺纹孔，用于车体连接。
进一步地，金属块的螺纹孔与上腔之间设有注油孔。
本发明的优点：
1）在皮碗边缘形成密封圈，可以有效的防止储油缸内的油液外泄。
2）皮碗底座与橡胶主簧和安装支架采用螺钉、凸缘连接，防止橡胶主簧失效，且可以防止油液泄漏，防止灰尘杂物进入。
3）减振器结构简单可靠，维修方便。
附图说明
图1为本发明的结构组成示意图。
图2为本发明的立体视图。
具体实施方式
下面结合具体附图和实施例对本发明作进一步说明。
一种油压减振器，如图1和图2所示，包括安装支架1、金属块2、橡胶主簧3、金属骨架4、上惯性通道5、下惯性通道6、皮碗底座7、解耦膜片8、皮碗9等零部件；
皮碗9安装在皮碗底座7内，所述皮碗底座7与皮碗9配合，皮碗9外圈凸起，形成密封圈与下惯性通道6紧密贴合，可以有效的防止储油缸内的油液从皮碗9与下惯性通道6间隙中泄露；皮碗9上方形成下腔11；皮碗底座7可采用塑料件；
橡胶主簧3采用镶嵌注塑，内部镶嵌金属骨架4和金属块2；金属块2位于橡胶主簧3上部中间，金属骨架4位于橡胶主簧3下部一圈；金属骨架4可以增强橡胶主簧3刚度；金属块2中间开有螺纹孔201，用于车体连接，同时金属块2在减振中有限位的作用；
橡胶主簧3的下方形成上腔10；安装支架1、橡胶主簧3和皮碗底座7边缘均具有凸缘302，且各自凸缘上设有相对应的固定孔301，通过螺钉穿过安装支架1、橡胶主簧3和皮碗底座7上的凸缘进行锁紧，有效防止油压减振器内部的油液溢出；也防止灰尘、杂物的进入；
上惯性通道5和下惯性通道6设置在橡胶主簧3与皮碗9之间的腔体内；上惯性通道5和下惯性通道6上均设有油通孔；解耦膜片8位于上惯性通道5和下惯性通道6中间。
在金属块2中，螺纹孔201与上腔10之间具有注油孔，用于注入油液；油液注入完毕后可以用密封件堵住注油孔，而金属块2通过螺纹孔201连接于车体后，可以将螺纹孔201内的密封件压住；
工作原理：这是一种油液单向流动的减振器，拉伸和压缩时，压力缸上腔的油液通过上惯性通道5经过下惯性通道6流入皮碗9中。
