Power distribution apparatus for a four-wheel drive vehicle

摘要

A hydraulic multi-plate clutch is disposed between a second gear for changing the transmission direction of drive force to a parallel position and an engine. An oil pressure driving portion for actuating the hydraulic multi-plate clutch comprises integrally an oil pressure control mechanism portion mainly constituted by an oil pressure control valve and oil paths, an oil pump and an electric pump motor which are adapted to generate hydraulic oil pressure and an accumulator for smoothing the hydraulic oil pressure to prevent pulsations, and is disposed at a substantially horizontal side position of the hydraulic multi-plate clutch.
