上述现有技术存在以下缺陷：
(1)制动液通过过滤网组件20和缸体进油接口10内壁间的间隙进入到离合器主缸的壳体内，制动液通过该间隙时流量减小，从而降低了制动液进入离合器主缸的壳体的效率。
(2)过滤网组件20的插入到缸体进油接口10的一端有一个底部柱形件201，其会阻碍制动液通过，而承受高压，这可能导致底部柱形件201和网片202之间的连接被破坏。

所述过滤组件包括彼此形成为一体的筒状的安装部和过滤部，
所述安装部与所述进液管的内周面过盈配合，从而将所述过滤组件定位在所述进液管内，所述安装部比所述过滤部靠所述进液管的所述一端。
在至少一个实施方式中，所述安装部包括直管段和锥形段，所述直管段将所述锥形段和所述过滤部连接在一起，所述锥形段的直径从所述直管段起沿着远离所述过滤部的方向逐渐增大。

本发明的过滤组件能够使液体通过第一滤网和第二滤网进出过滤组件，从而滤除液体中的杂质。第一滤网和第二滤网可以减小液体通过过滤组件的阻力。
在本发明的过滤组件的安装结构中，过滤部位于安装部的上游，特别地过滤部可以位于进液管中，液体经过过滤部流入安装部，然后从安装部流到离合器主缸的壳体中，这减小了液体通过过滤组件的阻力。
在本发明的进液管组件中，过滤组件定位在进液管中，在将进液管组件与离合器主缸的壳体装配时，只需将进液管连接到离合器主缸进液口即可，不必考虑过滤组件与离合器主缸进液口的装配，这简化了进液管组件到离合器主缸的安装。

具体实施方式
下面参照附图描述本发明的示例性实施方式。
在本说明书中，若没有特别说明，轴向A、径向R和周向C分别指根据本发明的过滤组件的轴向A、径向R和周向C。轴向一端是指图2至图8中的左侧 端，轴向另一端是指图2至图8中的右侧端。
第一实施方式
如图2所示，本实施方式的用于离合器主缸的过滤组件的安装结构包括离合器主缸进液口1、过滤组件2、进液管3和密封环4。过滤组件2插入进液管3内，离合器主缸进液口1插入进液管3内。密封环4安装在离合器主缸进液口1和进液管3之间，对离合器主缸进液口1和进液管3之间的连接部位进行密封。
如图2至图4所示，过滤组件2包括安装部和过滤部。安装部包括直管段21和锥形段22。过滤部包括滤网23和加强筋24。滤网23包括第一滤网232和第二滤网233。第一滤网232卷曲形成为筒状，第一滤网232的轴向一端开口，第一滤网232的轴向另一端连接第二滤网233，第二滤网233形成为圆板状，第二滤网233形成筒状的第一滤网232的底部。第一滤网232和第二滤网233设置有过滤孔231，过滤孔231用于过滤液体中的杂质。
锥形段22为圆锥台状，其具有能够使液体流过的第一通道。直管段21为圆筒状的空心管，其能够嵌合到、特别是过盈配合到离合器主缸进液口1内，直管段21具有能够使液体流过的第二通道。通过锥形段22将直管段21和滤网23的轴向一端(开口的一端)连接，使直管段21的第二通道经由第一通道和滤网23的内部连通。优选地，该第二通道与锥形段22的第一通道连续。
加强筋24包括第一加强筋241和第二加强筋242，从而提高滤网23的强度。第一加强筋241沿径向R延伸形成条状，第一加强筋241设置在第二滤网233上。第二加强筋242沿轴向A延伸形成条状，两条第二加强筋242在第一滤网23的周向上隔开大约180度。。通过第一加强筋241使两条第二加强筋242的轴向另一端连接，从而进一步提高滤网23的强度。
直管段21插入离合器主缸进液口1，使锥形段22的轴向一端面与离合器 主缸进液口1的端面相抵。
锥形段22的直径大于直管段21的直径。锥形段22的外周面能够和进液管3的内周面紧密配合，从而提高对过滤组件2的支撑。
锥形段22的轴向一端的直径大于锥形段22的轴向另一端的直径，从而锥形段22容易插入进液管3。在过滤组件2沿轴向A朝进液管3内插入过程中，使锥形段22的外周面与进液管3的内周面过盈配合，从而锥形段22的外周面和进液管3的内周面贴合。
在进液管3和离合器主缸进液口1的接头处，进液管3形成有内周面与锥形段22的外周面配合的锥状段。
非限制性地，进液管3的至少部分区域为波纹管。
在一个实施方式中，直管段21、锥形段22、滤网23和加强筋24由塑料制成，可以使用注塑工艺一体成型。在另一实施方式中，滤网23和过滤组件2的其它部分由不同材料制成。例如，滤网23可以由塑料或金属制成，过滤组件2的其它部分可以由塑料制成。
进液管3可以为低压油管，进液管3连接到储油罐(未示出)，储油罐内的液体通过进液管3经过滤组件2过滤后进入离合器主缸的壳体内。液体由滤网23进入过滤组件2内。液体经第一通道和第二通道通入到离合器主缸进液口1中，从而进入离合器主缸的壳体内。
在本实施方式中，由于过滤部(滤网23)容纳在进液管3中而非离合器主缸进液口1中，进液管的内径通常大于离合器主缸进液口1的内径，因而，液体能够顺畅地通过第一滤网232和第二滤网233进入到过滤组件2内，进而通过第一通道和第二通道流入离合器主缸。
直管段21和锥形段22确保了过滤组件的稳定安装，过滤部确保了液体顺畅进入过滤组件2，因而，本实施方式的过滤组件的安装结构可以减小液体 流过过滤组件的阻力。过滤部的端面包括第二滤网233，在第二滤网233上形成有与第二加强筋242连接的第一加强筋241，这在减小过滤部的端面的阻力的情况下，提高了滤网23的强度，可以避免过滤部因过大的液压力而破损。
第二实施方式
参照图5至图7说明根据本发明的第二实施方式的进液管组件。
如图5所示，根据本实施方式的进液管组件包括过滤组件2A和进液管3。过滤组件2A通过过盈配合安装在进液管3内。进液管3与离合器主缸进液口、密封环的连接方式可以和第一实施方式相同。
如图5至图7所示，本实施方式的过滤组件2A包括直管段21A、锥形段22A、滤网23A和加强筋24A。直管段21A为圆筒状，其具有能够使液体流过的第一通道。滤网23A包括第一滤网232A和第二滤网233A。第一滤网232A形成为筒状，第一滤网233A的轴向一端开口，第一滤网232A的轴向另一端连接第二滤网233A，第二滤网233A形成筒状的第一滤网232A的底部。第一滤网232A和第二滤网233A设置有过滤孔231A，过滤孔231A用于过滤杂质。第一滤网232A的轴向一端(开口的一端)与直管段21A连接。
加强筋24包括第一加强筋241A和第二加强筋242A，从而提高滤网23A的强度。第一加强筋241A沿周向C形成为环状。第二加强筋242A沿轴向A延伸形成条状，四条第二加强筋242A沿周向C分布设置在第一滤网232A的外周面和内周面。与仅在滤网的内侧或外侧设置加强筋相比，这提高了加强筋对滤网的加强作用。第一加强筋241A连接在第二加强筋242A的轴向另一端，使第二滤网233A位于第一加强筋241A限定的区域内，从而进一步提高滤网23A的强度。
如图5所示，进液管3至少部分区域为波纹管，锥形段22A的轴向一端的直径大于锥形段22A的轴向另一端的直径，从而过滤组件2A容易插入波纹 管。直管部21A的外周面通过过盈配合与波纹管的波纹部分装配。锥形段22A卡在波纹管的内周面的凹槽中，使过滤组件2A不会由于液体流过波纹管而移动。过滤部(包括加强筋)优选与进液管3的内周面间隔开，从而便于液体通过第一滤网232A和第二滤网233A进入过滤组件2A中。
在本实施方式中，可以从进液管3的一端开口将过滤组件2A插入到进液管3中。
在本实施方式的进液管组件中，过滤组件2A定位在进液管3中，在将进液管组件与离合器主缸的壳体装配时，只需将进液管3连接到离合器主缸进液口1即可，不必考虑过滤组件2A与离合器主缸进液口1的装配，这简化了进液管组件到离合器主缸的安装。
第三实施方式
如图8所示，根据本实施方式的进液管组件包括过滤组件2A和进液管3A。过滤组件2A通过过盈配合安装在进液管3A内。第三实施方式中的过滤组件2A与第二实施方式中的过滤组件2A相同，仅进液管3A以及进液管3A和过滤组件2A的安装不同。
如图8所示，进液管3A为软管，锥形段22A的轴向一端的直径大于锥形段22A的轴向另一端的直径，从而过滤组件2A容易插入软管。直管部21A的外周面通过过盈配合与进液管3A装配，相比于直管部21A，锥形段22A和进液管3A的过盈量更大，使过滤组件2A牢固地安装在进液管3A中。进液管3A可以具有光滑的内壁面。非限制性的，进液管3A可以采用EPDM材料制成。
当然，本发明不限于上述实施方式，本领域技术人员在本发明的教导下可以对本发明的上述实施方式做出各种变型，而不脱离本发明的范围。
(1)在第一实施方式中加强筋24设置在滤网23的外表面，在第二实施方式中加强筋24A设置在滤网23A的外表面和内表面。应当理解，在本发明中，加强筋还可以仅设置在滤网的内表面。
(2)在第一实施方式中，第一加强筋241呈条状，在第二实施方式中，第一加强筋241A为圆环状。在本发明中，第一加强筋还可以是十字交叉连接四条第二加强筋或以其他形状连接多条第二加强筋。
