Title:
ASPHALT FINISHER
Document Type and Number:
WIPO Patent Application WO/2011/135846
Kind Code:
A1
Abstract:
An asphalt finisher is provided with: an engine comprising a travel mechanism, a conveyor, a screw, and various screed mechanisms; a generator; a plurality of motors; an adjustment part; and a plurality of inverters. The generator generates electricity through the driving of the engine. Each motor drives a respective mechanism using power from the generator. The adjustment part adjusts the output voltage of the generator in such a manner that the output voltage of the generator attains a voltage within a prescribed range, even when a first rotational state exists in which the engine is at a relatively low engine speed, or when a second rotational state exists in which the engine speed is at a relatively high engine speed. Each inverter converts the output from the generator, the voltage of which has been adjusted by the adjustment part, to the desired frequency and supplies the output to each motor.
