Abstract
A differential device is equipped with differential gears 3 and a pair of output gears 5, 7 that mesh with the differential gears 3 in different meshing pitch-circle radii R1, R2. The output gears 5, 7 are formed by contrate gears, while the differential gears 3 are formed by spur gears.
Claims8
A differential device for a vehicle, comprising:
- differential gears to which a driving torque of a motor is inputted;
- and
- a pair of output gears that mesh with the differential gears to distribute the driving torque inputted from the differential gears to vehicle wheels, wherein
- the differential device is constructed so as to allow respective meshing pitch-circle radii of the output gears meshing with the differential gears to be changeable in compliance with a desired distribution ratio of the driving torque to be transmitted to the vehicle wheels.
