WHEEL DRIVING DEVICE AND WHEEL DRIVING METHOD FOR OF HYBRID CONSTRUCTION MACHINE

摘要

The present invention relates to a wheel driving device and a wheel driving method for a hybrid construction machine, and the wheel driving device drives a low-speed motor during low-speed driving and drives a high-speed motor during high-speed driving by turning a clutch on or off during low-speed driving or high-speed driving by means of a control unit and a transmission comprising the low-speed motor having a small capacity, the high-speed motor, and the clutch, which are respectively provided at all wheels in the construction machine having the wheels, particularly, a hybrid wheel loader, thereby reducing manufacturing costs of the wheel driving device, improving the fuel efficiency of the construction machine, reducing the wear of tires mounted on the wheels, improving the durability of the tires, and ensuring traveling stability.
