ABSTRACT:
A subpump assists a main pump for feeding hydraulic oil into a vehicle transmission system so as to control the distribution of the drive force transmitted to front and rear wheels. A motor for driving the subpump is started with a predetermined timing and energized for a predetermined drive time, so that the subpump circulates hydraulic oil with air which is mixed into the hydraulic oil by a chain that is turned in an oil tank, from a strainer chamber for the subpump, to prevent accumulation of air in the oil tank.
