过滤装置、变速器及车辆

Abstract

本实用新型提出了一种过滤装置、变速器及车辆，过滤装置包括壳体，壳体内设置有第一腔体，第一腔体上设置有第一滤泡部，第一滤泡部用于隔挡气泡以阻止气泡进入第一腔体内；第一吸滤器，设置于第一腔体内，第一吸滤器具有进油口和出油口，进油口与第一腔体内的空间连通，出油口用于与执行油路连通，第一吸滤器配置为对第一腔体输送至执行油路的介质进行过滤，其中，第一吸滤器的进油口处设置有第二滤泡部，第二滤泡部用于隔挡气泡以阻止气泡沿进油口进入第一吸滤器内。第一腔体内的油液同时通过第一滤泡部和第二滤泡部双重隔挡气泡后，再进入第一吸滤器内的油液中含气泡的数量大大下降，保证系统的可靠性。
