Benefits of technology

[0014]The present disclosure is directed to providing an apparatus for controlling the angle of a swash plate of

Problems solved by technology

Therefore, a driver should use a great force to manipulate the pedal 15, which results in inconvenient manipulation.
In addition, an electronic hydraulic valve 25 may be installed to perform automatic transmission suitable for conditions, but this configuration is expensive.
However, this configuration has a problem in that the electric motor 35 may not be easily controlled.
However, in this process, the angle of the swash plate 34 fluctuates within the control region, which causes the operating vehicle to fluctuate, makes the driver feel unpleasant and deteriorates the durability of the electric motor 35.
However, these solutions have problems in that the size of the motor increases or the cost increases.

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.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to Korean Patent Application No. 10-2011-0010608, filed on Feb. 7, 2011, and all the benefits accruing therefrom under 35 U.S.C. §119, the contents of which in its entirety are herein incorporated by reference.BACKGROUND[0002]1. Field[0003]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.[0004]2. Description of the Related Art[0005]A tractor or working vehicle may do plowing or flattening or other agricultural works using the power of an engine, and a loader or mower may be attached to the tractor to perform various kinds of works.
