KR950033070A - Hydraulic pump combined motor - Google Patents

Abstract

Starting motor and hydraulic pump are manufactured integrally, and the engine is operated as a starting motor during initial start-up, and the motor's hydraulic pump combined starting motor can be used as a hydraulic pump after starting. The electronic clutch, which is rotated by the operation of the low-pressure clutch, sucks the oil in the oil storage tank, the accumulator which keeps the oil discharged from the oil pump at a constant pressure and sends it to the hydraulic mechanism, and the engine And a controller for selectively operating an oil pump according to an initial state of the engine and an operating state of the engine based on an input signal of a sensor installed in the sensor, wherein the electromagnetic clutch comprises an electromagnetic coil surrounding the armature shaft and a rotatable armature shaft. And magnetized iron plate having a friction pad attached thereto to be magnetized when the electromagnet coil is energized. The friction pad is attached to the magnetized iron plate, and is composed of a clutch plate which is spline-coupled on the driving shaft of the oil pump to enable longitudinal movement.
