The utility model provides an integrated structure of a refueling screw plug and an air plug, which is arranged on the bridge housing body of the driving axle and consists of a gasket, a refueling screw plug, an air plug and an oil shield; the oil shield is welded on the bridge housing body by a C-shaped fillet weld; the gasket is sleeved in a guide groove in the middle of the outer side of the refueling screw plug, and the lower part of the refueling screw plug is threaded with the oil shield. The bridge housing body is firmly connected, and the gasket is pressed on the outer surface of the bridge housing body. The refueling plug is provided with a central through hole along the axis and an internal thread in the central through hole. The ventilation plug is connected with the refueling plug through the thread, and is connected with the bridge housing of the driving axle through the central through hole of the refueling plug to realize exhaust gas. The top of the refueling plug adopts a hexagonal bolt head structure. The utility model realizes that the filling screw plug and the ventilation plug are arranged on the upper part of the bridge housing body at the same time, thus saving cost, and eliminating the process of drilling the installation hole of the ventilation plug, so as to avoid misoperation.
【技术实现步骤摘要】
一种加油螺塞与通气塞一体集成结构
本技术属于汽车车桥结构设计
,具体涉及一种加油螺塞与通气塞一体集成结构。
技术介绍
在现有的驱动车桥结构中,加油螺塞布置在桥壳后盖上,而通气塞布置在桥壳本体的上方。此种结构,需在桥壳后盖上焊接螺塞座,以实现加油螺塞的安装,这无疑将增加制造成本;此外,还需要在桥壳本体上开设通气塞安装孔,但在实际操作过程中,由于操作失误,桥壳本体上的通气塞安装孔有时会出现没有钻通的情况,使得无法排气,导致驱动桥内油压过高,破坏油封的密封性能。
技术实现思路
针对上述现有技术中存在的缺陷,本技术提供了一种加油螺塞与通气塞一体集成结构,实现加油螺塞与通气塞同时布置在桥壳本体的上方,节约成本,且省去开钻通气塞安装孔的工序,避免误操作。结合说明书附图,本技术的技术方案如下:一种加油螺塞与通气塞一体集成结构,所述结构布置在驱动桥的桥壳本体上,由垫密片2、加油螺塞3、通气塞4以及挡油罩5组成;所述挡油罩5采用C形角焊缝焊接在桥壳本体1上;所述垫密片2套装在加油螺塞3外侧中部导槽内,所述加油螺塞3下部通过螺纹与桥壳本体1固连,并将垫密片2压紧在桥壳本体1外表面,所述加油螺塞3沿轴线开有中心通孔,中心通孔内开有内螺纹,所述通气塞4通过螺纹连接在加油螺塞3上,并通过加油螺塞3的中心通孔与驱动桥的桥壳内部联通。所述加油螺塞3的顶部采用六角螺栓头结构。与现有技术相比,本技术的有益效果在于:1、本使用新型所述加油螺塞与通气塞一体集成结构将加油螺塞布置在桥壳本体的上方,相对于布置在桥壳后盖上,无需在桥壳后盖上焊接螺塞座,直接降低了成本;2、本使用新型所述加油螺塞与通 ...
