POWER TRANSMISSION SYSTEM FOR CONSTRUCTION MACHINERY
A power transmission device of a construction machine, transmitting a driving force of an engine to a wheel, includes: a travel pump driven by the engine to discharge a work hydraulic pressure in one of a first direction and a second direction; an auxiliary pump configured to form a pilot hydraulic pressure; a direction switching valve configured to control a swash plate of the travel pump through the pilot hydraulic pressure; a main pilot flow path configured to supply the pilot hydraulic pressure supplied from the auxiliary pump to the direction switching valve; a travel motor of which a rotation direction is determined according to a discharge direction of the travel pump; and a first pilot flow path branched from one side of the main pilot flow path and supplying the pilot hydraulic pressure to control a capacity of the travel motor.
