A POWER TRANSMISSION SYSTEM OF THE OIL PRSSURE PUMP FOR THE ELECTRIC CONSTRUCTION WORK VEHICLE

摘要

PURPOSE: A power transmission system of a hydraulic pump for an electric construction work vehicle is provided to maintain environment-friendly and economic work environment by reducing pollution due to the exhaust gas of the fuel consumption. CONSTITUTION: A power transmission system of a hydraulic pump for an electric construction work vehicle comprises followings. A hydraulic pump rotated by a PTO(Power Take Off) axis is installed at one side of a power drawing device drawing the power of an engine from a transmission for an electric construction work vehicle. An electromagnetic clutch(34) is installed at one side of the hydraulic pump(30). An inverter motor(40) in which a drive pulley(42) is formed to be parallel to the hydraulic pump is installed. The electromagnetic clutch and the drive pulley engage with a drive belt(44).
