The invention relates to the technical field of engineering mechanical transmission systems, in particular to a wet type electric drive axle of a loading machine. The differential mechanism comprises a differential mechanism shell, a half shaft sleeve, a hub and a brake device. The half shaft penetrates through the half shaft sleeve, is connected to the hub and is used for driving the hub to rotate; lubricant and a brake device are arranged in the hub, the brake device is composed of a stop ring, a stop sleeve and a brake mechanism, and the locking function is achieved through abutting connection of an inner friction plate and an outer friction plate. The brake mechanism controls contact and separation of an inner friction plate and an outer friction plate through changes of a thrust sleeve and an expansion cavity, and efficient and reliable brake performance is ensured. In addition, the reset mechanism ensures the stability and reliability of the system through a reset spring. The technical effect of improving the braking reliability and maintenance convenience of the wet-type electric drive axle of the loading machine is achieved.

    本申请涉及工程机械传动系统技术领域,尤其是涉及一种装载机湿式电驱动桥。其包括差速器壳体、半轴套管、轮毂及刹车装置。半轴贯穿半轴套管并连接在轮毂上,用于驱动轮毂转动;轮毂内部设有润滑剂和刹车装置,其中刹车装置由止动环、止动套及制动机构组成,通过内摩擦片与外摩擦片的抵接实现锁止功能。制动机构利用推力套和膨胀腔体的变化来控制内摩擦片与外摩擦片的接触与分离,确保高效可靠的制动性能。此外,复位机构通过复位弹簧保证了系统的稳定性和可靠性。本申请达到了提高装载机湿式电驱动桥的制动可靠性和维护便利性的技术效果。
