Abstract
A driving torque distribution apparatus has a rapid response speed by applying a ball ramp device including a ball which is rolling-supported between a worm wheel rotated by a worm gear and a cam ring fixed in a rotation direction, and configured to generate an axial directional pressurizing force in conjunction with the rotation of the worm wheel, as first and second operation units to control first and second clutch units, and is configured so that an axial directional load due to pressurizing forces of the first and second operation units is canceled within each drum by a snap ring and a spacer fixed to internal and external sides of each drum of the first and second clutch units, preventing an interface between axial directional loads acting on the first and second clutch units.
