阅读说明：本技术 减压式变速箱油滤清器 (Pressure-reducing type gearbox oil filter ) 是由 叶升孟 黄建栋 陈瑞慈 饶春燕 叶南海 刘万斌 于 2021-08-03 设计创作，主要内容包括：本发明公开了一种应用于汽车的减压式变速箱油滤清器,包括壳体、壳盖,在该壳体与壳盖之间装有过滤网,在所述壳体上、并在壳体的进油口处装有粗滤网,在所述壳体上、并在壳体的进油口的侧边处装有磁铁。本发明让变速箱机油循环过滤时,先流经粗滤网以及磁铁侧边处,对变速箱机油进行粗过滤并让机油内的铁性杂质被磁铁所吸附,后再经过滤网进行细过滤。该过滤及吸附工艺简单,安装方便,有效减轻了过滤网部分的过滤压力,使变速箱机油滤清器的过滤效率与使用寿命得到提升,使整个油滤清器具有最佳的过滤效果,从而保证变速箱系统的正常运行。(The invention discloses a decompression type gearbox oil filter applied to an automobile, which comprises a shell and a shell cover, wherein a filter screen is arranged between the shell and the shell cover, a coarse filter screen is arranged on the shell and at an oil inlet of the shell, and a magnet is arranged on the shell and at the side edge of the oil inlet of the shell. When the engine oil of the gearbox is circularly filtered, the engine oil of the gearbox flows through the coarse filter screen and the side edge of the magnet, is coarsely filtered, iron impurities in the engine oil are adsorbed by the magnet, and then is finely filtered through the filter screen. This filtration and adsorption process is simple, and simple to operate has effectively alleviateed the filter pressure of filter screen part, makes the filter efficiency and the life of case speed changing machine oil cleaner obtain promoting, makes whole oil cleaner have the best filter effect to guarantee the normal operating of gearbox system.)

具体实施方式

参照图1至图3可知，本发明应用于汽车的减压式变速箱油滤清器，包括壳体1、壳盖3，在该壳体1与壳盖3之间装有过滤网2(为细滤、精滤)，在所述壳体1上、并在壳体的进油口7处装有粗滤网6(为粗滤)，在所述壳体1上、并在壳体的进油口的侧边处装有磁铁5(为若干件，分布于侧边周围)。

在该壳体1上设有进油口7、在该壳盖3上设有出油口8，在所述壳盖3上、并在壳盖的出油口8处装有密封圈4，用于此油滤清器与变速箱装配的密封性能处理。所述磁铁5通过固定夹9装在壳体1上，以方便拆卸并及时清理磁铁上的铁性杂质。

在变速箱内的机油循环流动过滤时，先进入壳体1的进油口7流经粗滤网6以及磁铁5侧边处，对变速箱内的机油进行粗过滤，并让机油内的铁性杂质被磁铁所吸附，然后再经过滤网2进行细过滤，并从壳盖3的出油口8流出。
