Limited slip differential with full differential lock drive subassembly

A limited slip differential with full differential lock drive subassembly, the differential comprising:

• a ring gear;
• a ring gear hub coupled to the ring gear, the ring gear hub having a ring gear central passage, the ring gear hub including a plurality of spaced bosses extending from an inside end surface of the ring gear hub that define a plurality of spaced holding slots;
• a carrier coupled to the ring gear hub;
• a first side gear received within the ring gear hub, the first gear including an extending side gear flange having spaced side gear slots, the side gear flange is positioned between the plurality of spaced bosses of the ring gear hub and an inside side surface of the ring gear hub;
• a second side gear received within the carrier;
• a plurality of spider gears configured to convey torque between the first side gear and the second side gear;
• a first clutch pack configured to selectively convey friction torque between the ring gear and the first side gear, the first clutch pack positioned in the ring gear hub with at least a portion of the first clutch pack positioned radially between the plurality of spaced bosses and the ring gear central passage, wherein the first clutch pack includes a plurality of friction plates and a plurality of reaction plates selectively positioned in relation to each other to achieve a desired friction in the first clutch pack, wherein each reaction plate of the plurality of reaction plates includes an extending plate tab that is positioned between an associated holding slot of the plurality of spaced holding slots of the ring gear hub to lock rotation of the plurality of the reaction plates to rotation of the ring gear hub;
• a second clutch pack configured to selectively convey friction torque between the carrier and the second side gear;
• and
• an engagement dog configured to selectively lock rotation of the ring gear hub to the first side gear when a lock configuration is selected, the engagement dog including a plurality of spaced engaging fingers, each engaging finger of the plurality of spaced engaging fingers of the engagement dogs passing through an associated ring gear slot of a plurality of ring gear slots in the ring gear hub to be selectively received in an associated gear slot of a plurality of the spaced gear slots in the gear flange of the first gear to selectively lock rotation of the first gear to rotation of the ring gear hub.

A vehicle that includes a limited slip differential with full differential lock drive subassembly, the vehicle comprising:

• a motor configured to generate motor torque;
• a gear box to communicate the motor torque to a plurality of wheels;
• and
• the limited slip differential with the full differential lock drive subassembly including,
• a ring gear;
• a ring gear hub coupled to the ring gear, the ring gear hub having a ring gear central passage, the ring gear hub including a plurality of spaced bosses extending from an inside end surface of the ring gear hub that define a plurality of spaced holding slots extending from an inside end surface of the ring gear hub;
• a carrier coupled to the ring gear hub;
• a first side gear received within the ring gear hub, the first gear including an extending side gear flange having spaced side gear slots;
• a second side gear received within the carrier;
• a plurality of spider gears configured to convey torque between the first side gear and the second side gear;
• a first clutch pack configured to selectively convey friction torque between the ring gear and the first side gear, the first clutch pack positioned in the ring gear hub with at least a portion of the first clutch pack positioned radially between the plurality of spaced holding slots and the ring gear central passage;
• a second clutch pack configured to selectively convey friction torque between the carrier and the second side gear;
• and
• an engagement dog configured to selectively lock a rotation of the first side gear ring gear to a rotation of the ring gear hub by selectively engaging at least one side gear slot in the side gear flange of the first gear when the differential is in a lock configuration.
