Abstract
A limited slip differential for a vehicle includes a differential gear case, and first and second side gears supported by the differential gear case. The first and second side gears are engaged with each other along an interface, and the interface a non-flat profile, such as a conical or frustoconical profile. Depending on the angle of the conical or frustoconical profile, a torque bias ratio (TBR) of the limited slip differential can be adjusted.

A limited slip differential comprising:
- a differential gear case;
- and
- first and second side gears supported by the differential gear case;
- wherein the first and second side gears are engaged with each other along an interface;
- wherein the interface has a non-flat profile;
- wherein the non-flat profile is a conical or frustoconical profile;
- and
- wherein the interface comprises less than 50% of a diameter of the side gears.

Side gears for a limited slip differential comprising:
- a first side gear having a first cross-sectional profile;
- and
- a second side gear having a second cross-sectional profile;
- wherein the first cross-sectional profile and the second cross-sectional profile are mating cross-sectional profiles;
- wherein the first side gear and the second side gear are configured to be supported in the limited slip differential such that they can engage each other along an interface of the mating cross-sectional profiles;
- and
- the interface has a non-flat profile;
- wherein the non-flat profile is a conical or frustoconical profile;
- and
- wherein the interface comprises less than 50% of a diameter of the side gears.
