The invention discloses a broken shaft type single-side drive rear axle, which belongs to the technical field of electric tricycles, and comprises a gear box, two axle tubes and hubs, a power half shaft is arranged in one axle tube, one end of the power half shaft is connected with the gear box, and the other end of the power half shaft is in transmission connection with the hub on the same side to form a driving transmission structure; one end, far away from the gear box, of the other axle tube is connected with a supporting shaft to form a suspension shaft, and the supporting shaft is inserted into and supported in the central shaft hole of the hub on the same side. The power half shaft is fixedly connected with the differential case, the power half shaft drives the hub on the same side to rotate, and the supporting shaft is fixed to the axle tube on the same side and supports the hub on the same side to rotate; the differential case drives the power half shaft to rotate unilaterally to form unilateral driving, so that when the differential case drives the single half shaft to rotate, transmission points are reduced, noise can be reduced to 70-75db, and the performance and riding comfort of a rear axle are improved.

    本发明公开了一种断轴式单边驱动后桥,属于电动三轮车技术领域,包括齿轮箱、两个桥管以及轮毂,其中一个桥管内设置有一动力半轴,动力半轴的一端与齿轮箱连接,另一端与同侧轮毂传动连接,形成主动传动结构;另一个桥管远离齿轮箱的一端连接有支撑轴,形成悬浮轴,支撑轴插入并支撑在同侧轮毂的中心轴孔内,本发明通过动力半轴与差速器壳固定连接,动力半轴对同侧轮毂驱动旋转,支撑轴固定在同侧桥管并支撑同侧轮毂转动,使差速器壳单边驱动动力半轴转动,形成单边驱动,因此差速器壳体带着单个半轴转动时,传动点减少,能够将噪音降低至70‑75db,提高了后桥的性能和乘坐舒适性。
