下面结合图1至图13对本发明实施例的油罐总成100进行详细描述，该油罐总成100可以为转向油罐，但不限于此。
根据本发明实施例的油罐总成100，可以包括罐体110、气道圆盘120和挡油圆盘130。
其中，如图2和图4所示，罐体110具有腔体101且腔体101顶部敞开以形成开口，油液可以通过开口被注入到腔体101中，罐体110靠近开口的内侧设有第一止挡部111，第一止挡部111可以阻挡油液从腔体101中飞溅出来。
气道圆盘120至少部分地伸入到腔体101内，也就是说，气道圆盘120的一部分伸入到腔体101中，气道圆盘120的另一部分置于腔体101外。具体地，伸入到腔体101内的部分为长条形结构，置于腔体101外的部分为圆盘形结构，所述圆盘形结构可以用于阻止腔体101内的油液飞溅出去。
挡油圆盘130设在气道圆盘120伸入到腔体101内的部分上，且挡油圆盘130的外周缘位于第一止挡部111的内周缘的外侧，挡油圆盘130的外周缘与第一止挡部111间隔开以形成第一通道103，第一通道103与外部空间连通。
也就是说，挡油圆盘130在水平面的投影与第一止挡部111在水平面上的投影具有重合的部分。挡油圆盘130的外周缘与第一止挡部111间隔开以形成第一通道103，腔体101内向上飞溅的油液的大部分可以被挡油圆盘130和第一止挡部111所阻挡，只有一小部分会通过第一通道103，第一通道103主要是为了连通腔体101与外部空间。
根据本发明实施例的油罐总成100，通过在罐体110上设置第一止挡部111和挡油圆盘130，且挡油圆盘130与第一止挡部111配合，可以有效避免油液从罐体110中飞溅出来造成油罐总成100漏油。
在本发明的一些实施例中，如图3和图5所示，罐体110的内侧还设置有第二止挡部112，第二止挡部112置于第一止挡部111的上方且与第二止挡部111在上下方向间隔开。
通过第一通道103的一小部分油液会被第二止挡部112所阻挡，且由于第二通道104的间隙很小，油液不会通过第二通道104，进而有效避免了油液飞溅到室外。
在本发明的一些实施例中，如图3和图5所示，第一止挡部111在从外向内的方向上向下延伸，挡油圆盘130设在第一止挡部111的上方，且挡油圆盘130在从内向外的方向上向下延伸。
也就是说，第一止挡部111的外周缘的位置比其上的其他部分的位置都低，挡油圆盘130的内周缘的位置比其上的其他位置都低；第一止挡部111可以构造成中部开口的圆盘， 第一通道103被限定为一个圆环形的通道。
第一止挡部111可以与罐体110一体形成，也可以通过焊接或粘结的方式固定在罐体110内部。
有利地，如图3和图5所示，第二止挡部112设在开口的周缘处且向下延伸。也就是说，第二止挡部112与罐体110的横截面构造为勾状，通过第一通道103的油液不能继续向上飞溅，而是会被向下延伸的第二止挡部112所阻挡。
第二止挡部112可以与罐体110一体成型，也可以通过焊接或粘结的方式固定在罐体110上。
在本发明的一些实施例中，罐体110还包括压紧垫片140，压紧垫片140的外周缘的一部分止抵在第二止挡部112上，压紧垫片140的外周缘的另外一部分与第二止挡部112间隔开以形成第二通道104，第二通道104分别与第一通道103和外部空间连通。
如图3、图5和图11所示，压紧垫片140的外周缘的所述一部分向上弯曲以形成止抵部141，压紧垫片140的外周缘的所述另外一部分向下弯曲以形成限位部142，止抵部141止抵在第二止挡部112上，限位部142用于对弹性件150进行限位。
止抵部141为多个且沿周向均匀间隔分布，在第二止挡部112上可以设有同等数量且沿周向均匀间隔分布的安装槽，在安装压紧垫片140时，首先将止抵部141对应放置在多个安装槽内，然后旋转压紧垫片140，使得止抵部141压紧在第二止挡部112安装槽外的其他部分上，安装槽的深度很浅且该安装槽可以作为第二通道104。
在本发明的一些实施例中，油罐总成还包括弹性件，弹性件150弹性地抵压在挡油圆盘130和压紧垫片140之间。由此，在压紧垫片140止抵在第二止挡部112上时，弹性件150会向下压紧挡油圆盘130，且由于挡油圆盘130设在气道圆盘120上，进而气道圆盘120也会有向下移动的趋势。
弹性件150可以为弹簧，限位部142可以设置在弹性件150的外周，进而可以有效避免弹性件150发生移动。
在本发明的一些实施例中，如图3和图5并结合图7和图8所示，气道圆盘120包括置于腔体101外的本体部121以及置于腔体101内的安装部122，安装部122上设有台阶部122a，挡油圆盘130卡设在台阶部122a上。
如图5、图8至图9所示，安装部122上设有用于连通第二通道104与外部空间的第三通道105。
进一步地，为了确保罐体110的内部空间与外部空间连通，避免由于第三通道105被堵塞而造成罐体110的内部空间与外部空间不连通，安装部122上还可以设有用于连通第二通道104与外部空间的第四通道106。
在本发明的一些实施例中，如图1、图6和图12所示，油罐总成100还包括罐盖160，罐盖160安装在本体部121上，罐盖160与本体部121限定出连通第三通道105和/或第四通道106与外部空间的第五通道107。罐盖160可以粘结固定在本体部121上，也可以与本体部121为一体成型件。
优选地，如图3、图6和图13所示，油罐总成100还包括密封垫片170，密封垫片170压紧在气道圆盘120与罐体110的顶部之间以密封开口的外周缘，进而可以起到密封油液和阻挡外部的灰尘进入到腔体101中。
密封垫片170可以为橡胶材质的环形结构，该环形结构可以套设在气道圆盘120上，且在罐盖160安装在罐体110上时，密封垫片170过盈配合在气道圆盘120与罐体110的顶部之间，罐盖160可以在弹性件150的作用下被压紧在密封垫片170上。
罐体110和挡油圆盘130的材质可以为钢材，也可以是塑料件，密封垫片170的材质可以为聚四氟乙烯。
如图12所示，罐盖160的内侧面上可以设置有多个沟槽108，如图8和图9所示，本体部121的顶面上可以设有多个密封壁121a，多个密封壁121a可以紧贴在沟槽108的内壁上，由此可以进一步避免油液的外泄。
下面简单描述本发明实施例的车辆。
根据本发明实施例的车辆包括上述实施例的油罐总成100，由于本发明实施例的车辆设置有上述的油罐总成100，因此该车辆的不容易漏油，降低了车辆的使用成本。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
