A differential gear unit for a vehicle includes: an annular ring gear arranged to be rotatable about a rotation axis extending in an axial direction; a first side gear configured to distribute a first output torque to the first drive shaft and a second side gear configured to distribute a second output torque to the second drive shaft; and at least a first differential pinion and a second differential pinion rotatably disposed on the pinion pin and configured to engage the first side gear and the second side gear. The differential gear unit further comprises a decoupling element arranged radially on the inside of the ring gear, the decoupling element being rotatably arranged relative to the ring gear. The pinion pin is connected to the decoupling element and extends in the diametrical direction to the decoupling element. The differential gear unit also includes a clutch sleeve slidably disposed in the axial direction relative to the ring gear and the decoupling element. When displaced in the axial direction, the clutch sleeve is configured to: disconnect the ring gear from the decoupling element in a first axial position to allow a rotational movement of the decoupling element relative to the ring gear; connecting the ring gear to the decoupling element in a second axial position to prevent a rotational movement of the decoupling element relative to the ring gear; and connecting the ring gear with the park-lock structure in a third axial position.

    一种用于车辆的差速器齿轮单元包括:被布置成能够围绕在轴向方向上延伸的旋转轴线旋转的环形齿圈;第一侧齿轮和第二侧齿轮,第一侧齿轮被构造成用于将第一输出扭矩分配到第一驱动轴上,第二侧齿轮被构造成用于将第二输出扭矩分配到第二驱动轴上;能够旋转地布置在小齿轮销上的至少第一差速器小齿轮和第二差速器小齿轮,其被构造成用于接合第一侧齿轮和第二侧齿轮。差速器齿轮单元还包括沿径向布置在齿圈的内侧的去耦元件,其中,去耦元件相对于齿圈能够旋转地布置。小齿轮销与去耦元件相连并且在直径方向上延伸过去耦元件。差速器齿轮单元还包括在轴向方向上相对于齿圈和去耦元件能够滑动地布置的离合器套筒。离合器套筒在沿轴向方向移位时被构造成用于:在第一轴向位置将齿圈与去耦元件断开连接,以允许去耦元件相对于齿圈的旋转运动;在第二轴向位置将齿圈与去耦元件相连,以防止去耦元件相对于齿圈的旋转运动;以及在第三轴向位置将齿圈与停车‑锁定结构相连。
