Abstract
An electronic controlled coupling including a wet-type multiple disc clutch, a coupling case, a hydraulic chamber, an oil pump, an electric motor, an electric control unit, and a supply passage for supplying hydraulic pressure. The coupling case accommodates the wet-type multiple disc clutch and contains oil. The oil pump driven by the electric motor is connected to the coupling case. The outlet of the oil pump is connected to the hydraulic chamber of the wet-type multiple disc clutch with the supply passage therebetween. The electric control unit controls the speed of rotation of the electric motor through a motor driver so that the pump discharge pressure is equal to an operating pressure required for the wet-type multiple disc clutch. The electronic controlled coupling performs a complete coupling mechanism increasing the durability as a coupling and a compact and simple structure enhancing the flexibility in designing.
