Document Type and Number:
WIPO Patent Application WO/2018/061578
Kind Code:
A1
Abstract:
This power transmission device for a work vehicle comprises: a generator which generates electric power using the power of an internal combustion engine; an electric motor which generates drive power using the electric power generated by the generator; a travel device which travels using the drive power generated by the electric motor; a phase-modulation circuit which has capacitors that are connected in series between the generator and the electric motor and switching elements that are connected to the positive electrode side and the negative electrode side of the capacitors; and a control device which modulates the phase of the current to be supplied to the electric motor from the generator by switching the switching elements and switching between the charged state and the discharged state of the capacitors.
