The invention discloses a heavy-duty car axle rear cover assembly, and belongs to the technical field of driving device accessories. The rear cover assembly comprises a body, an annular connector is arranged at the connecting end of the body and the axle housing, a connecting cylinder is arranged on the axle housing, the connector is located outside the connecting cylinder, and the connector is fixedly connected with the axle housing; a first sealing ring is clamped in the connector, a second sealing ring is arranged on the connecting cylinder, the connector is connected with the body through a connecting section, a sealing cavity for containing inert gas is formed among the connecting section, the first sealing ring, the second sealing ring and the connecting cylinder, and a sealing plug for plugging the inflation inlet is arranged on the connecting section. A filtering device for filtering lubricating oil in the axle housing is arranged on the body, an oil filling port is formed in the body, and the oil filling port is sealed through a sealing plug. By the adoption of the axle rear cover assembly of the heavy-duty car, the problems that an existing axle rear cover and an axle housing are poor in sealing performance, low in connection strength and poor in lubricating oil filtering effect can be solved.
本发明公开了一种重型汽车车桥后盖总成,属于驱动装置配件技术领域。后盖总成包括本体,本体与桥壳连接端设置有环形的连接头,桥壳上设置有连接筒,连接头位于连接筒的外部,连接头与桥壳固定连接;连接头的内部卡设有第一密封圈,连接筒上设置有第二密封圈,连接头与本体之间通过连接段连接,连接段、第一密封圈、第二密封圈和连接筒之间形成容纳惰性气体的密封腔,连接段上设置有将充气口进行封堵的封堵塞;本体上设置有对桥壳内的润滑油进行过滤的过滤装置,本体上设置有加油口,加油口通过密封塞密封。本发明采用上述重型汽车车桥后盖总成,能够解决现有的车桥后盖与桥壳之间密封性差、连接强度低,润滑油过滤效果差的问题。
