Abstract
The present disclosure relates to an apparatus for controlling the angle of a swash plate of a hydraulic pump, and more particularly, to an apparatus for controlling the angle of a swash plate of a hydraulic pump in order to fix the swash plate at a desired angle by using an electric motor and an electromagnet. The apparatus for controlling the angle of a swash plate of a hydraulic pump includes a swash plate and a swash plate shaft coupled to the swash plate to be rotatable, and the apparatus further includes: an electric motor which directly connects the swash plate shaft or transmits a rotating force through a link connected to the swash plate shaft to pivot the swash plate; and an electromagnet which generates a magnetic force so that the swash plate moving according to the operation of the electric motor is fixed at a target angle.
