Title:
DRIVING FORCE DISTRIBUTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/024540
Kind Code:
A1
Abstract:
A driving force distribution device: in which distribution of the driving force to the driven wheels is possible by bringing a first roller, which rotates with the main driving wheel transmission system, into contact with a second roller, which rotates with the driven wheel transmission system, at the outer circumferential surfaces of the two so as to allow power transmission; and which controls the distribution of the driving force between the main driving wheels and the driven wheels by supporting the shaft of the second roller so as to rotate freely in an eccentric hole of the crankshaft, which is capable of rotating around an axis for securing the housing, and rotating the second roller by rotation of the crankshaft around the securing axis to adjust the pressing force of the second roller with respect to the first roller in the radial direction. The driving force distribution device is formed so that by using the motor to rotate a pinion that engages with ring gears, which protrude in the radial direction of the crankshaft on both sides of the second roller in the axial direction, the crankshaft is rotated around the securing axis and the axial direction length of the second roller, which applies the pressing force on the first roller, becomes longer than the axial direction length of the first roller.
