Title:
ELECTRIC POWER UNIT
Document Type and Number:
Japanese Patent JP2014163503
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem that in a conventional electric power unit for outputting rotational power from an electric motor as driving force of a driven part, speed/direction of the driving force cannot be quickly and smoothly changed.SOLUTION: In an electric power unit 26 for outputting rotational power from an electric motor 68 as driving force of a driven part, a hydraulic infinite variable-speed drive 69 for fluid-connecting a hydraulic motor 73 to a hydraulic pump 72 to be driven by the electric motor 68 by a closed circuit 71 and a rack-and-pinion mechanism 70 to be driven by the hydraulic motor 73 are integrally combined.
