The invention discloses an integrated transmission shell, a single-motor electric drive axle assembly and a double-motor electric drive axle assembly. The problems that an existing electric drive axle assembly is insufficient in strength, and the sealing performance of motors is difficult to guarantee are solved. The axle housing specifically comprises a housing body, a first ring cover, a second ring cover, a third ring cover, a fourth ring cover and an axle housing connecting plate, an input shaft bearing through hole, an output shaft bearing through hole and an intermediate shaft bearing through hole are formed in the shell body; the first ring cover is arranged on one face of the shell body and surrounds the periphery of the input shaft bearing through hole, the periphery of the output shaft bearing through hole and the periphery of the middle shaft bearing through hole. The side wall of the first ring cover is provided with a gear shifting control window, and the inner wall is correspondingly provided with a gear shifting fork shaft hole; the second ring cover, the third ring cover and the fourth ring cover are arranged on the other surface of the shell body; the second ring cover is arranged around the input shaft bearing through hole; the third ring cover is arranged around the output shaft bearing through hole; the fourth ring cover is arranged close to the second ring cover; an oil outlet hole is formed between the fourth ring cover and the second ring cover; the axle housing connecting plate is fixed to one side of the housing body.
本发明公开了一种集成式变速器壳体及单电机、双电机电驱桥总成,解决了现有的电驱桥总成强度不足、难以保证电机的密封性的问题。具体包括壳本体、第一环罩、第二环罩、第三环罩、第四环罩及桥壳连接板;壳本体上设有输入轴轴承通孔、输出轴轴承通孔及中间轴轴承通孔;第一环罩设于壳本体一面,并环绕在输入轴轴承通孔、输出轴轴承通孔及中间轴轴承通孔外围;第一环罩的侧壁上设换挡操纵窗口,内壁对应设有换挡拨叉轴孔;第二环罩、第三环罩及第四环罩均设于壳本体另一面;第二环罩绕输入轴轴承通孔设置;第三环罩绕输出轴轴承通孔设置;第四环罩靠近第二环罩设置;第四环罩与第二环罩之间设置有出油孔;桥壳连接板固定在壳本体一侧。
