The invention relates to an electric wheel of a multi-axle transport vehicle, and belongs to the technical field of off-highway transport vehicles. A traction motor of the electric wheel is in transmission connection with a hub and a rim through a speed reducing mechanism and is fixedly connected with a rack front seat extending out of a central sleeve, and the central sleeve penetrates through a brake inner gear ring and extends into a central hole of a hub connecting frame; the braking inner gear ring and the hub connecting frame are restrained in the circumferential direction and limited in the axial direction. A wet brake located in the wet brake space is installed outside the brake inner gear ring, a spacer on the innermost side of the brake inner gear ring is connected with the outer end of a brake piston, and the outer circle of the brake piston is in movable fit with a piston end cover. The end part of the central sleeve is butted and fixedly connected with the frame rear seat; and the hub is supported by the outer circle of the frame rear seat. The multi-disc wet brake is ingeniously arranged in a limited space, the problem of assembly interference is well solved through the split rack structure, stable and reliable operation and braking performance of the electric wheel of the multi-shaft transport vehicle is practically guaranteed, and the service life is long.
本发明涉及一种多轴运输车电动轮,属于非公路运输车辆技术领域。该电动轮的牵引电机通过减速机构与轮毂和轮辋传动连接,并与延伸出中央套管的机架前座固连,中央套管穿过制动内齿圈并伸入轮毂连接架的中央孔;制动内齿圈与轮毂连接架周向约束且轴向限位;制动内齿圈外装有位于湿式制动空间的湿式制动器,其最内侧的隔离片与制动活塞的外端衔接,制动活塞的外圆与活塞端盖动配合;中央套管端部与机架后座对接固连,机架后座的外圆支撑轮毂。本发明不仅将多片湿式制动器巧妙安置在有限空间内,而且通过分体机架结构妥善解决了装配干涉难题,切实保证了多轴运输车电动轮的运行及制动性能稳定可靠,并且使用寿命长。
