Abstract
A differential gearing device includes a base gearing device and an actuator. The base gearing device including a first gear connected to a first output of the differential gearing device, a second gear connected to a second output of the differential gearing device, differential gearing connected to each of the first gear and the second gear, and a clutch connected between the first gear and the second gear. The actuator actuates the clutch to change a torque bias ratio between the first gear and the second gear.
Claims6
A differential gearing device, comprising:
- a base gearing device including
- a first gear connected to a first output of the differential gearing device,
- a second gear connected to a second output of the differential gearing device,
- differential gearing connected to each of the first gear and the second gear, and
- a clutch connected between the first gear and the second gear;
- and
- an actuator that actuates the clutch to change a torque bias ratio between the first gear and the second gear, wherein
- the differential gearing includes a pair of helical gears in mesh with each other, a first helical gear of the pair of helical gears in mesh with the first gear, and a second helical gear of the pair of helical gears in mesh with the second gear,
- the clutch is disposed radially inside of at least one of the first gear and the second gear, and
- the differential gearing is radially outward of the first gear and the second gear.
