Abstract: A differential gear arrangement for a vehicle. The differential gear arrangement includes a ring gear, a spindle gear, a spindle gear carrier, a side gear and an output shaft. The spindle gear is carried by the spindle gear carrier and rotatable relative to the spindle gear carrier. The spindle gear and the side gear are engaged with each other. The side gear is rotationally connected to the output shaft. The ring gear is arranged to drive the output shaft by rotating the spindle gear carrier when the ring gear and the spindle gear carrier are rotationally connected to each other. The ring gear and the spindle gear carrier are rotationally disconnectable from each other by axial displacement of the spindle gear carrier relative to the ring gear and the output shaft.
