The invention discloses a through-type axle housing integrated with a gear shifting mechanism, which belongs to the technical field of electric drive axle housings and comprises a shifting fork shaft which penetrates through an axle housing body in a sliding manner and is parallel to the central axis of the axle housing body, and a shifting fork connected with the shifting fork shaft is arranged in the axle housing body; a telescopic cylinder connected with one end of the shifting fork shaft and a locking nut for sealing the other end of the shifting fork shaft are mounted on the axle housing body. A shifting fork shaft in the gear shifting mechanism is directly installed on the axle housing body in a sliding and penetrating mode, a telescopic cylinder is controlled to drive the shifting fork shaft and a shifting fork to slide in the axial direction, and therefore the reliable and stable gear shifting function is achieved. The gear shifting mechanism is directly integrated on the axle housing body, the structure is simple and compact, the assembling performance is good, and a gear shifting executing mechanism is high in reliability and good in practicability.

    本发明公开一种集成换挡机构的贯穿式桥壳,属于电驱桥桥壳技术领域,包括滑动贯穿桥壳本体并与桥壳本体中轴线平行设置的拨叉轴,桥壳本体内部设有与拨叉轴连接安装的拨叉;桥壳本体上安装有与拨叉轴一端连接的伸缩缸和对拨叉轴另一端密封的锁紧螺母。换挡机构中的拨叉轴直接滑动贯穿安装于桥壳本体上,通过控制伸缩缸带动拨叉轴和拨叉进行轴向滑动,从而实现可靠稳定的换挡功能;换挡机构直接集成于桥壳本体上,结构简单、紧凑,装配性能好,换挡执行机构可靠性高,实用性好。
