The invention relates to the technical field of differential mechanisms, in particular to a differential device and a dual-drive power device. The differential device comprises a left outer wheel and a right outer wheel, the right outer wheel and the left outer wheel are coaxially arranged on a center line; the outer planet wheel is arranged on a planet carrier and is in meshed connection with the left outer wheel and the right outer wheel respectively; the left inner wheel is arranged between the left outer wheel and the right outer wheel, and the axis of the left inner wheel extends along the center line; the right inner wheel is arranged between the left outer wheel and the right outer wheel, and the center line of the right inner wheel extends along the center line; and the inner planet wheel is arranged on the planet carrier and is respectively meshed and connected with the left inner wheel and the right inner wheel. The differential device is compact in structure, small in occupied space and easy to arrange and install, the rotating speed difference of the two drivers can be automatically balanced, and the requirement for a control algorithm is effectively lowered.
本发明涉及差速器技术领域,特别涉及一种差速装置及双驱动动力装置。其中,差速装置包括:左外轮;右外轮,右外轮与左外轮同轴设置在一中心线上;外行星轮,外行星轮布置在一行星架上并分别与左外轮及右外轮啮合连接;左内轮,左内轮布置在左外轮与右外轮之间并且其轴线沿中心线延伸;右内轮,右内轮布置在左外轮与右外轮之间并且其中线沿中心线延伸;和内行星轮,内行星轮布置在行星架上并分别与左内轮及右内轮啮合连接。该差速装置结构紧凑、占用空间小,易于布置和安装,能够自动平衡两个驱动器的转速差,有效降低对控制算法的要求。
