Title:
TORQUE TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/056178
Kind Code:
A1
Abstract:
Provided is a torque transmission device capable of achieving as much compactness as possible in a direction in which a pair of side gears are provided side-by-side while ensuring a differential function and a differential limiting function. The invention is provided with: side gears (5L, 5R) connected to rear wheels (3L, 3R); a case (6) positioned on the outer circumference side of the side gears (5L, 5R), said case (6) rotating around the axis of the side gears (5L, 5R); and a pinion gear (12) rotatably supported by the case (6) and meshing with the side gears (5L, 5R) when straddling both. The side gears (5L, 5R) are configured by spur gears having differing numbers of teeth. The pinion gear (12) is a spur gear and is positioned such that the axial direction of the pinion gear (12) faces in the same direction as the axial direction of the side gears (5L, 5R), and a motor (15) is associated with the pinion gear (12).
