The invention relates to the technical field of automobile part structures, in particular to a normally open differential and an automobile. Comprising a differential shell, a planet shaft gear structure, a connecting gear ring, a driving structure and a reset structure, the planet shaft gear structure comprises a planet shaft, a planet gear sleeved on the planet shaft, two half shaft gears arranged on two sides of the planet shaft respectively and in meshing transmission connection with the planet gear, and a combined gear ring sleeved at the end part of the planet shaft; a rack structure is arranged between the connecting gear ring and the combined gear ring, and when the connecting gear ring is tightly attached to the axial end face of the combined gear ring, the connecting gear ring and the combined gear ring are fixedly connected in the rotating direction around the first axial line. The driving structure is connected to one end of the connecting gear ring back to the combining gear ring; the reset structure is used for driving the connecting gear ring to move towards the side away from the combined gear ring so that the connecting gear ring can be disengaged from the combined gear ring. The differential mechanism is simple in structure and convenient to operate and use, machining difficulty and machining cost are reduced, and torque transmission is smoother and more stable.
本发明涉及汽车零部件结构技术领域,具体地指一种常开式差速器及汽车。包括差速器壳体、行星轴齿结构、连接齿环、驱动结构和复位结构,行星轴齿结构包括行星轴、行星轴上空套着行星齿轮、分置于行星轴两侧且与行星齿轮啮合传动连接的两个半轴齿轮以及环套在行星轴端部的结合齿环;连接齿环与结合齿环之间设置有在连接齿环紧密贴合到结合齿环轴向端面时使两者在绕第一向轴线转动方向上固定连接的齿条结构;驱动结构连接于连接齿环背向结合齿环的一端;复位结构用于驱动连接齿环向远离结合齿环一侧移动使连接齿环与结合齿环脱离。本申请的差速器结构简单,操作使用方便,降低了加工难度和加工成本,使扭矩传递更为平顺和稳定。
