The invention relates to a parallel eccentric coupling which comprises an input part, an output part and a parallel connecting rod mechanism. The input part can be in transmission connection with a power source. The output part can be in transmission connection with the driven part. The parallel connecting rod mechanism comprises an input parallel connecting rod assembly and an output parallel connecting rod assembly; a near-end connecting rod in the input parallel connecting rod assembly and the input part rotate synchronously; a far-end connecting rod in the output parallel connecting rod assembly and the output part rotate synchronously; and a far-end connecting rod in the input parallel connecting rod assembly is fixedly connected with a near-end connecting rod in the output parallel connecting rod assembly. The invention further relates to an electric wheel comprising the parallel eccentric coupling. The parallel connecting rod mechanism in the parallel eccentric coupling has theadvantages of being stable and compact in structure; only a cake-shaped movement space is needed in the transmission process; the axial size of the parallel eccentric coupling can be effectively reduced; and the parallel eccentric coupling is suitable for being mounted in the electric wheel.
本发明涉及一种平行偏心联轴器,包括输入部、输出部和平行连杆机构。输入部能够与动力源传动连接。输出部能够与从动件传动连接。平行连杆机构包括输入平行连杆组件和输出平行连杆组件,输入平行连杆组件中的近端连杆与输入部同步转动,输出平行连杆组件中的远端连杆与输出部同步转动,输入平行连杆组件中的远端连杆和输出平行连杆组件中的近端连杆固定连接。本发明还涉及一种包括上述平行偏心联轴器的电动轮。上述平行偏心联轴器中的平行连杆机构具有结构稳定、紧凑的优点,在传动过程中也仅仅是需要大致呈圆饼状的运动空间,能够有效减小平行偏心联轴器的轴向尺寸,适用于安装在电动轮内。
