Limited slip differential unit

A driveline, comprising:

• a power source having a power source output shaft;
• a first reduction comprising an input pinion coupled to and driven by the power source output shaft and a first intermediate gear mounted on an intermediate shaft and meshed with the input pinion;
• a second reduction comprising a second intermediate gear driven by the first intermediate gear and an output gear driven by the second intermediate gear;
• and
• a limited slip differential coupled to the output gear, the limited slip differential comprising:
• a two-piece differential case including:
• a first differential case piece with the output gear coupled thereto;
• and
• a second differential case piece removably coupled to the first differential case piece;
• an intermediate floating piece positioned radially inward from the second piece and including a pin and planet gears rotatably coupled to the pin, wherein the intermediate floating piece is coupled to the differential case via splines that enable the intermediate floating piece to slide axially in relation to the differential case;
• a first side gear and a second side gear meshed with each of the planet gears;
• a first disc spring mounted on the first side gear and a second disc spring mounted on the second side gear;
• a first clutch pack mounted on the first side gear and positioned between the first disc spring and a lip of the first side gear;
• a second clutch pack mounted on the second side gear and positioned between the second disc spring and a lip of the second side gear;
• and
• a shim mounted on the second side gear and positioned axially between the second disc spring and the two-piece differential case;
• wherein each of the first side gear and the second side gear are configured to exert axial force in an outward direction and activate a respective clutch pack of the first clutch pack and the second clutch pack in response to a respective wheel of a first drive wheel and a second drive wheel experiencing resistance that is greater than a preload applied to the respective clutch pack of the first clutch pack and the second clutch pack by a respective disc spring of the first disc spring and the second disc spring.

A driveline, comprising:

• a first axle shaft coupled to a first drive wheel;
• a second axle shaft coupled to a second drive wheel;
• a power source configured to distribute torque to the first drive wheel and the second drive wheel via the first axle shaft and the second axle shaft, respectively;
• and
• a limited slip differential configured to control distribution of torque between the first drive wheel and the second drive wheel in response to resistance experienced by each of the first drive wheel and the second drive wheel, the limited slip differential comprising:
• a differential case including:
• a first differential case piece with a gear coupled thereto;
• and
• a second differential case piece removably coupled to the first differential case piece;
• an intermediate floating piece positioned radially inward from the second piece and including a pin and planet gears rotatably coupled to the pin, wherein the intermediate floating piece is coupled to the differential case via splines that enable the intermediate floating piece to slide axially in relation to the differential case;
• a first clutch pack and a first disc spring mounted on a first side gear that is meshed with the intermediate floating piece and coupled to the first axle shaft;
• and
• a second clutch pack and a second disc spring mounted on a second side gear that is meshed with the intermediate floating piece and coupled to the second axle shaft;
• wherein each of the first side gear and the second side gear are configured to exert axial force in an outward direction and activate a respective clutch pack of the first clutch pack and the second clutch pack in response to a respective wheel of the first drive wheel and the second drive wheel experiencing resistance that is greater than a preload applied to the respective clutch pack of the first clutch pack and the second clutch pack by a respective disc spring of the first disc spring and the second disc spring.
