Document Type and Number:
WIPO Patent Application WO/2021/065193
Kind Code:
A1
Abstract:
The present invention makes it possible to easily control drive sources that impart driving force to a right front wheel and a left front wheel. This work machine is provided with a right rear wheel, a left rear wheel, a right front wheel, and a left front wheel. The work machine is provided with a first sensor for measuring the rotation speed of the right rear wheel, and a second sensor for measuring the rotation speed of the left rear wheel. The work machine is provided with a first drive source for imparting driving force to the right front wheel, and a second drive source for imparting driving force to the left front wheel. The work machine is provided with a control unit (50). The control unit (50) controls the first drive source such that the right front wheel rotates at the same rotation speed as the rotation speed of the right rear wheel, as measured by the first sensor. The control unit (50) controls the second drive source such that the left front wheel rotates at the same rotation speed as the rotation speed of the left rear wheel, as measured by the second sensor.
