The steering gear comprises a steering input shaft, a steering output shaft, a power assisting module and a speed reducer module, the speed reducer module comprises a speed reducer shell, an eccentric transmission shaft and an eccentric connecting shaft, the steering input shaft is rotatably connected with the power assisting module, and the power assisting module is in power connection with the eccentric transmission shaft. An inner gear ring is arranged in the speed reducer shell, the eccentric transmission shaft is sleeved with an eccentric transmission gear, the eccentric connecting shaft comprises a first shaft part and a second shaft part, the first shaft part and the second shaft part are connected, the axes of the first shaft part and the second shaft part are distributed in a staggered mode, the first shaft part rotatably penetrates through the transmission gear, and the second shaft part rotatably penetrates through the steering output shaft. The transmission gear is meshed with the inner gear ring, and the tooth number of the transmission gear is smaller than that of the inner gear ring so that small-tooth-difference transmission can be achieved between the transmission gear and the inner gear ring. According to the steering gear, the steering gear can output large torque in a pure electric power assisting mode, and therefore the use requirement of a vehicle is met.

    本发明公开了一种转向器和车辆,所述转向器包括:转向输入轴、转向输出轴、助力模块和减速器模块,减速器模块包括减速器壳体、偏心传动轴、偏心连接轴,转向输入轴可转动地与助力模块相连,且助力模块与偏心传动轴动力连接,其中,减速器壳体内设有内齿圈,偏心传动轴外套设有偏心设置的传动齿轮,偏心连接轴包括第一轴部和第二轴部,第一轴部和第二轴部相连且轴线错开分布,第一轴部可转动地穿设于传动齿轮,第二轴部可转动地穿设于转向输出轴,传动齿轮与内齿圈啮合,且传动齿轮的齿数少于内齿圈的齿数以与内齿圈少齿差传动。本发明的转向器,能够用纯电动助力形式使转向器输出较大扭矩,从而满足车辆的使用需求。
