TORQUE TRANSMISSION DEVICE
First Claim
1. A torque transmission device comprising:
- a pair of side gears arranged facing each other on the same axis and respectively coupled as a torque output member to a wheel on one side and a wheel on the other side of a vehicle;
a supporting member rotating around the axis of the pair of the side gears as a torque input member; and
a pinion gear rotatably supported by the supporting member and engaged with the pair of the side gears in a straddling manner,the pair of the side gears being configured as cylindrical gears having teeth disposed on either an outer circumferential surface or an inner circumferential surface, the side gears having the numbers of teeth different from each other,the pinion gear being a cylindrical gear having teeth disposed on an outer circumferential surface, the teeth engaging with the pair of the side gears,the pinion gear being disposed with an axial direction of the pinion gear directed in the same direction as the axial direction of the pair of the side gears,the pinion gear being associated with a rotation drive source applying rotation corresponding to a running state of the vehicle.

Abstract
A torque transmission device is provided that is capable of being compactified as much as possible in a direction of parallel arrangement of a pair of side gears while ensuring a differential function and a differential limiting function. The torque transmission device comprises side gears (5L, 5R) coupled to rear wheels (3L, 3R), a case (6) disposed on the outer circumferential side of the side gears (5L, 5R) and rotating around the axis of the side gears (5L, 5R), and a pinion gear (12) rotatably supported by the case (6) and engaged with the side gears (5L, 5R) in a straddling manner. Additionally, the side gears (5L, 5R) are made up of spur gears different in the number of teeth, the pinion gear (12) is a spur gear and is disposed with an axial direction thereof directed in the same direction as the axial direction of the side gears (5L, 5R), and the pinion gear (12) is associated with a motor (15).
