Differential and vehicle including the same

A vehicle comprising:

• a first differential configured to allow a difference in speed between left and right wheels of a main driveshaft in the vehicle;
• a first limited-slip differential configured to selectively restrict a differential operation of the first differential;
• a second differential configured to allow a difference in speed between left and right wheels of an auxiliary driveshaft in the vehicle;
• a second limited-slip differential configured to selectively restrict a differential operation of the second differential;
• and
• a disconnecting device provided on the auxiliary driveshaft and configured to selectively block power transmitted from a driving source to the auxiliary driveshaft,
• wherein the first differential includes:
• a first ring gear;
• a first differential case connected to the first ring gear and rotating integrally with the first ring gear;
• a first spider gear rotatably mounted on the first differential case and rotating and revolving around the main driveshaft;
• and
• a pair of first side gears rotatably mounted on the main driveshaft and gear-engaged to the first spider gear,
• wherein the second differential includes:
• a second ring gear;
• a second differential case connected to the second ring gear and rotating integrally with the second ring gear;
• an auxiliary differential case configured to be selectively coupled to the second differential case by the disconnecting device;
• a second spider gear rotatably mounted on the auxiliary differential case and rotating and revolving around the auxiliary driveshaft;
• and
• a second side gear rotatably mounted on the auxiliary driveshaft and gear-engaged to the second spider gear,
• wherein the disconnecting device separates or couples the second differential case and the auxiliary differential case, and
• wherein the disconnecting device includes a sleeve slidably coupled to the second differential case and selectively coupled to the auxiliary differential case.
